TASK SPECIFIC SPACES

Post 594 by Gautam Shah (14 of 16 Behaviour in Spaces)

.

Spaces are multitasking facilities. Spaces have varied segments and environmentally transient locations to allow different activities to converge and separate in time and locations. A task is an identifiable work-lot for productive effort, relaxation or passing engagement. It is a work module that requires an area, specific environmental conditions, certain physiological capacities, few postural variations, set of tools and amenities, intra-personal facilitation, psychological makeup, intent and motivation. Other concerns for conducting tasks are safety, health, comfort, stability, mobility, consistency, variety, physical reach, cognition, sense of productivity, energy-conservation, ecological engagements, learning and cultural inhibitions.

Task Recognition makes way for efficiency and productivity. Tasks need to be recognized in terms of the location, schedule and environmental conditions. Tasks are better managed, if perceived as a part of routine and sequence. The routine recognizes common factors between tasks, casual tasks are once in a while endeavour, whereas sequential tasks optimize the postural change, site shifting, usage of amenities and facilities by participating members, and adjust intense work and rest periods.

Routine tasks are associated with the same location, time schedule, fixed structures, amenities, facilities and environmental conditions. Routine tasks are also very dependent on group behaviour dynamics. Routine tasks require very little shifting or rescheduling and so are very productive. The location is maintained because the space segment, with some consistent qualities can expand and contract to meet the occasional needs of the individual or group. Locations for routine tasks being consistent evolve with a lot of personalization such as enrichments. Such locations, because of their consistency and permanency, become the marked spaces or architectural units (bathing area, hay chopping area, etc.). Routine tasks with acute time domination cannot generally afford the luxury of space shifting, because identical environmental conditions are difficult to set elsewhere.

Casual tasks are tactical solutions rather results of any strategic planning. Casual tasks are ‘once in a while process’. The exigency is to accomplish the task in with whatever locational conditions, and as quickly as possible. Casual tasks overcome the shortcomings of the space size, form, environmental conditions, and problems with group behaviour dynamics. Casual tasks are ‘exciting’ as these open-up new possibilities of space and time management. Casual tasks also generate new group behaviour dynamics and intra-personal relationships.

Sequential tasks result from continuous work processes between equipments or participants, or both. Sequencing is required where the work steps are preceding-anteceding or back-feed or forward-feed are required. These can happen with batch or stream-line production processes. For example for cooking an efficient work triangulation is proposed, the nodes consist of basic amenities like cooking, sink and refrigerator (could change with culture and technology) and the connections denote the preparation, defrosting and storing, respectively. Similar task management techniques with robots are used for automobile assembly lines. Streamlined production plants like garments, electronics, consumer white goods recognize working of each task and the interim carryover periods and spaces.

Consistency and Variety are required in task handling. It can be achieved by doing a different task, or the same task differently. For these tasks are set in different spatial and environmental conditions and often with new intra-personal setting.

Task Productivity is greatly affected by the work setting formed by the space and environment. Wherever and whenever there is realization that task productivity is not of the comparative societal standards, the space is reformatted to realign the amenities, facilities and architectonic elements. Here at one end the functional efficiencies are re-validated, and at the other end environmental controls are reset. New group dynamics of intra-personal relationships also upgrade the productivity.

Learning and Improvisations are inevitable part of task handling. Tasks’ spread, effort and time of accomplishment are continuously appraised requiring minor changes in the processes. By rationalizing task spreads one reduces the physical energy of reach. Re-planning of efforts cut the number of processes. Time management achieves faster delivery. Oft repeated tasks is always the most improvised one.

Physical Reach and Physical Capacities define the number of sub-tasks or processes that can be handled without requiring shifting or rescheduling. These two, in a way also determine the dependence on tools, equipments, structures, amenities, facilities for carrying out tasks. Physical reach and capacities are governed by the posture taken for the task.

Housewives have accepted platform type of kitchen over floor level cooking in a crouching position because the later was restrictive. A corner study table allows greater reach then a straight table. An aged person prefers a straight seat with handles as it allows an easy rise up off the chair.

Social Factors operate at two levels: Group behaviour dynamics and the traditions, taboos, etc. Intra-personal interactions, even if nonverbal, act as a relief in task handling. Socially siting and scheduling of tasks affects the group behaviour dynamics. The tasks and group behaviour are inseparable. Customs and taboos result from the local perceptions and experiences, and so same tasks could have different time and space setting (ethnic variations) across societies. These are more apparent in craft related tasks.

Stability and Mobility related to transient positions and postures. Architectural features, facilities, tools and equipment and other participants are used for these purposes. Mobility is required to change the orientation, position and work-ability, which in interim processes in oft-repeated tasks.

Task attachment or anchorage results from need for personal support and stability and dependence on entities like: space forms, environmental conditions, structures, amenities, facilities and enrichments.

Bhunga houses have door thresholds as the commandeering location. Huts and one room house use inside front-corner for cooking because from the door an outsider would not see what is being cooked. Kitchens have platforms (or centralized work stations) attached to the wall for accessing services. Some tasks have sanctimonious associations and so are oriented to specific directions (like Mecca, East-Sun). One of the most preferred of orientations, are the openings’ systems like door, window, or a gap, because it extends the vision and allows to command further. Orientation is a biological preference as well as cultural conditioning and accordingly people prefer left or right turning.

Tasks extremely dependent on fixed amenities cannot be shifted, however, sub-tasks dependent on multiple processes needs to shift around wherever these are available. Tasks that require different space spreads for various processes and may need re-siting. Task handling efficiency derives when wait for the right occasion or search for the right location is minimal. Tasks are nominally positioned (and shifted around) within the same space segment and scheduled (and switched around) in the same time section. But some tasks are ‘shifted to other space segments or deferred in time’. Such shifts in space and switches in time occur primarily for functional needs, but often to relieve the tedium and for experimentation. Tasks are also switched to different schedules and locations to develop new intra-personal equations or group behaviour mechanisms. Tasks, which flourish within groups, may ignore time and space convenience.

DESIGN CONSIDERATIONS for DAYLIGHTING

Post 593 by Gautam Shah

.

Daylighting is illuminating the interiors of built spaces with the sunlight, as available during the sun up period. This is controlled entry of natural light and diffuse skylight into a building to reduce electric lighting and saving energy. The ‘direct’ daylight arrives through openings like doors, windows, skylights and other gaps. Indirect daylight is brought in as Diffused sky light from surface reflectors or Transmitted light through tubes and other devices.

Daylighting depends on the external conditions, such as the season of the year, climate, dust, fog or cloud cover, time of the day, terrain or surroundings. Daylight can be designed through buildings, size (spread or massing, depth, floor heights), form or shape, orientation, scheduling and location of tasks, configurations of openings, etc. It is closely linked to saving energy used for lighting during daytime. Daylight is substantially dependent on openings like doors and windows, and this help creates stimulating and natural environment.

Daylighting is dependent on external conditions. The season of the year determines not only the ‘sunshine’ days and brightness, but the direction (solar inclination) of the light. The climatic conditions govern if fenestrations can be kept fully open or closed. Local atmospheric conditions like dust, fog, cloud cover and pollution affect the intensity of daylight. Activities must be scheduled according to the diurnal cycle and positioned as per the available exposure. The surroundings’ factors, such as the terrain slopes, colour (of white sand beach fronts, green lawns or foliage, water bodies), and reflective capacities determine the brightness level of illumination.

640px-libya_4432_ghadames_luca_galuzzi_2007

Sahara Town Ghadames Libya > Wikipedia image by Luca Galuzzi http://www.galuzzi.it

Daylighting and building design, have mutual dependence. The exposure of the face, surface area, perimeter and form of the buildings can be advantageously exploited for better gain of daylight.

Daylighting for energy saving must be conceived with a view to reduce the artificial illumination requirements of deep-set spaces, low height spaces, isolated interior entities like vestibules and corridors. A synergetic system to calibrate the electric illumination can be created for task-need and occupancy of the space, compensative distribution (elimination of glare-contrasts) and low heat output.

Fenestrations and Daylighting are linked. Fenestration location (wall, skylights), height, shape and construction affect the daylighting. Fenestrations also serve the purpose of comfort (ventilation requirements such as heat gain-loss, air-moisture control, interior pollutant dilution, air movements) and view in-out, so must incorporate these requirements.

.

Daylight used for illuminating interior spaces, exploits the ever-changing quality in terms of intensity, colour and direction of the light. The daylight-design, scatters the light over a wider extent, diffuses its intensity and subdues the strong directionality, alters the colour quality, and shifts the location of the source.

Light intensity is a function of season, orientation and fenestration design. These are important considerations for siting an activity. Light intensity is perceived against the brightness level of the background scene or the surfaces. It can also be altered by illumination from other directions or additional artificial sources.

Colour of the daylight as reflected sky component have small colour variations, except the occasional colour scattering at sun rise and set periods. Daylight received from reflected surfaces such as terrain, near by buildings and plants has a colour tinge. The colour of the glazing material, colour of the opening cover systems like Venetian blinds, curtains, overlay films, etc. side-surfaces of fenestration systems.

Direction of the light is an important consideration for ingress or avoidance direct sunlight. North light (South light in S-hemisphere), are designed to access best natural illumination for industrial plants. East side facing openings allow ‘cool’ brightness in comparison to West faces.

Scattering the light over a wider area achieves equal brightness by avoiding high-low contrast or patchy areas. This is done by multiple openings or by masking the opening with diffuser screens. Scattering is avoided where dramatic effects are intentionally created such as vestibules, entrance halls, etc. Equalization of illumination in space is also achieved by electronic sensors that activate electric illumination in required intensity.

640px-taliesen-drafting-studio

Diffusing the intensity of light is resorted to reduce the high level of brightness on summer or clear sky afternoon periods. This is done by automatic masking devices or by baffles or louvers with apertures attuned to non-bright exposure-directions and schedules. Diffusers are also used to reduce the level of brightness in areas that act as transition spaces to darker environments such as auditoriums.

Calibrating a strong sense directionality with illumination is necessary to reduce the dynamism of direct natural illumination. Architectural openings like doors and windows bring in variations of brightness (movement of clouds), shadows of moving objects (trees, vehicles, other traffic), and variations of colours into the interior spaces. This changeability is often an irritant for work areas like laboratories, libraries, bedrooms, etc. By sourcing the daylight from multiple directions, the illumination can be made static and multilateral.

Altering the colour quality where colour perception is important such as in surgical and pathological areas of hospitals, colour and dye manufacturing plants, film and media editing rooms. Here not only the colour must be neutral but consistent. This is achieved by avoiding light reflected from external sources, such as pavings, walls and lawn or green foliage.

Shift the location of the source is important for space planning design at micro level. The available natural source may have strong left or right, up or down delineation and may need the shift of illumination location. This is done by external and internal reflecting surfaces or use of light transmission tubes.

STYLING the STYLE – Part 1

Post 592 by Gautam Shah

.

A style is a distinctive involvement by an individual. This approach is perceived by others to have diverse potential for application, in the same or different practices. The expression, in the physical work or the discourse, results from the local environment, such as the climate, geography, the society and the times. This gets also reflected in many other aspects of innovators’ personal lifestyle, and in some form dissipates in the society. So a personal style becomes universal by emulative confirmation. Some elements of the original style seem to persist in spite of the new environment, such as culture, technology, field of application and mode of expression.

Mannerism spreads in a different locality, time period, different forms and fields. This shifting of emulation by individuals could be for a while, sporadic, but a group coalesces to propound it vigorously as cultural heritage or innovative approach. The select components include colour, pattern, form, emphasis, representation or construction, perceptive likeness and abstract or unknown conveyance of meaning.

600px-cmoc_treasures_of_ancient_china_exhibit_-_pictorial_brick_depicting_a_courtyard_scene

Pictorial brick depicting a Chinese Courtyard Wikipedia image by Editor at Large

The first art-form to be emulated were the uttered sounds. A community impresses other ‘neighbours’ by the arrangement, succinct meaning and the ‘manner’ of conveyance. These were intricately connected to universal conditions like postures, gestures, tools, foods, and rituals like hunting, caring for children, birth, death etc. The local character to the utterances was endowed by the spatial acoustics (of terrain and built spaces) and environmental affectations. The next art forms were the personalization of the body, tools, utilities and habitable environs. These patterns and colours were regional and tribe-based, due to local material resources and used for ‘universal conditions’.

640px-masques_bakongo

These forms were initially representations of the ‘culture’ but not stylized expressions. But few individuals were proficient in it. These were the mannerist of the society, appreciated for the skill and copied by others. But the mannerisms spread from local to regional segments. The spread was slow in time, and became diffused with distance. The operative distance was what one could travel, and recall the practice. The mannerists were not classicists to be discussed or commented upon by the critics. And wherever these practices, were fortified by terrestrial seclusion or political isolation, became ethnic traditions.

No one had qualms about adapting, converting and mixing influences like Gods, fables, heroes, religious rights, drama characters, dogmas, recipes, motifs, festivals, dresses and adornments. This was part of personal creativity, but was also used for convincing a sponsor or buyer for it. Roman art is influenced by neighbouring cultures but was also used for the rulers. ‘Roman art periods are branded with rulers or dynasties’ and not by the art-creators. Roman arts and crafts in spite of adaptations from others, and after being ‘emulated by other across times and territories, maintains its own essence.

Any art-form, be it a personal statement or representation of ‘manner’ can be analyzed, on hindsight, into various effects. It originates from time and space realities. Its components find justification or raison d’etre when distanced. Most styles are identified by critics or rivals more for deriding it rather than appreciating it. Historic art and architectural styles were identified after the relevant periods were nearly extinct, or its originators not in practice. This was perhaps due to lack of faster communication and wider dissemination. Lack of communication did not allow immediate coalescence of thoughts and dissemination was slow as image transmission was nearly nonexistent. The art-forms, such as art, architecture could only be visited or transmitted over longer duration. The essence of the style, however, spread through many crafts, artefacts, adornments, performing arts, literature, etc.

Monkeys as Judges of Art > Wikipedia image by Gabriel von Max (1840-1915)

This spread became faster and intensive during the Industrial age for several reasons, publication of quality images through print media, faster and easier travel by steam-power over land and sea, weakening of the moneyed sponsorship by likes of church, industrial houses, political powers, etc. and greater distribution of arts and crafts. Creative people began to interact with others more frequently, who unlike the non-practicing critics were less derisive. The creators on their own were more conscious of meaning of expression and were self-critic.

LONELINESS, ALIENATION and SPATIAL BEHAVIOUR

Post 591 by Gautam Shah (13 of 16 Behaviour in Spaces)

.

A space arouses many types of emotions. Some of these caused by physiological and psychological conditions, and may disappear in the next visit or through continuing encounters. Somewhere external interventions are required to reset the sensorial perceptions and associated implications of the space. The other, an internal process redefines the space for spatial accommodation.

640px-rotterdam_cube_house_living_room

The sensorial perceptions relate to how a space ‘feels’ in nominal and extra ordinary environments and usage. The strangeness of the experience arises from associations one establishes and expectations evoked. Both are triggered by the past, and show up as human behaviour. There are many, happy, sad, strange, familiar, predictable, abhorrent and pleasant spatial experiences. Some inspire or force to change the space but other numb you to leave it.

Loneliness is an anxious feeling about a lack connectedness. It is experienced in absence or presence of people, and in known as well as unknown surroundings. The causes of loneliness are many such as social, mental, emotional, physiological and spiritual.

Loneliness > Flickr image by Antoine K

Causes for Loneliness are: Loss of a relationship due to breakup, travel, death of a person, dejection or withdrawal from a social circle, enforced isolation like jail or punishment like over stay at school or workplace, unfamiliar lifestyle, food and community leading to home sickness, a dysfunction of communication channels at places with low population densities, during periods of harsh climates, and fewer people to communicate with due to language, sex, social or other barriers.

Loneliness can be attributed to personal need, period, place and people. A person when isolated may feel lonely, but it is not always due to isolation. Solitude could be by choice, and so loneliness is a subjective experience. People can be lonely in a crowded or public place, because a person may be desiring more intensive social interaction than what is currently available, or the surroundings are not suitable for such opportunities. A person can be in the middle of a party and feel lonely due to inability to participate in it. Contrary to this one can be alone and yet not feel lonely, if there is no need or desire for social interaction.

Loneliness tends to depress some but improves the cognition and improves capacity to concentration. Study rooms, prayer or meditation zones, contemplation areas, private consultation rooms, lovers’ corners in restaurants, back seats in assembly halls are designed to be less participatory. Such places of solitude or temporary loneliness lead to enhanced and creative expression. Solitude is also associated with spiritual and religious quests.

For solitude, other then isolation from the people, some control over cognition may be necessary. Complete absence of cognition or by totally filtering an aspect of it (such as sound, light, touch, smell, etc.) in a space may create an uncomfortable situation. In jails and study rooms some illumination, background noise, distant odours are desirable to maintain the mental health. Loneliness should be considered as an alert that it is time to seek social connections. Connections of this nature, may not occur with presence of people, but rather by necessary adaptation of the living space.

Astronauts and Cosmonauts are checked for their mutual compatibility for Long stay on International Space Station

Russian space psychologists analyze the body language and tone of voice to ensure compatibility of crew members. Members of a group must have a strategy of a good working relationship. One may not be very friendly with a companion, but a clear understanding as to how much you are ready to share and not share, creates a healthy relationship. The Shuttle-Mir missions of the 1990s Russian and American crew had problems of language and other communications, leading to isolation.

Loneliness is going to be a major issue for long duration space travel with few crew members. For some persons the problem will not be loneliness but too much of the same company. The privacy of space may not be feasible, but of few exclusive moments will be appreciated.

Loneliness is also an issue with elderly people, staying in Old-age homes, hospitals and alone. They need someone to talk and respond, visually see the company, and touch. A robot seal is designed to improve all such sensorial functions. Space travelers will perhaps have such robots..

Alienation reflects the quality of association, one establishes with space and its occupants. It largely manifests from the expectations what a space should be. It includes spatial quality marks such as scale, size, shape, environment and control. One transcends from the familiar capacity to alter to the realization of inability to change a space.

640px-wadala_slums_-_mumbai

Inability to change the spatial character / Wadala slums Mumbai > Wikipedia image by Swaminathan Bangalore India 

The space is expected to offer segments that support the intra-personal encounters, but may fail to provide the required environment, amenities and sequential opportunities. Alienation does not set in as one frame, event or happening, but builds up pace by pace. But it may disappear very fast as soon as one establishes a link to the familiar. A light or trace of fresh air in dark space, a familiar face, or few words of known language change the space perspective.

640px-fredrick_douglass_housing_project_towers_2010

Alienated Housing of Fredrick Douglass Project Detroit > Wikipedia image by Albert duce

Alienation vanishes with slight change in the spatial quality marks but may be prevented by inculcating the individual capacity to alter the space. A highly defined and over detailed space configuration may retard the alterations. Buildings that have high imprint of their creators, (monumental edifices) have such issues. Alienation also arises when space scales and sequential approach system to it are not sufficiently stretched in time and space. Interim spatial occupation can go a long way in reducing the alienation.

SPATIAL DISTANCING and BEHAVIOUR

Post 590 by Gautam Shah (12 of 16 Behaviour in Spaces)

.

Spatial Distance means:

1 Size of intervening space, (between people-people and people-objects),

2 Perceptive extent of space

3 Reach in space.

Distance is also formatted by environmental factors, social requirements, psychological make-up, nature of communication, expression, scale and use of spatial objects, and time duration of the affectation. Spatial distance affecting the behaviour is perceived to be in touching, threatening, disturbing or overwhelming. Such interpretations vary with culture.

640px-state_library_of_victoria_-_left_side

Spatial Distancing > Wikipedia image by Diliff

 Four distinct zones within which interpersonal transactions normally take place:

■ Intimate distance is used in intimate relationships such as for embracing, kissing, touching or whispering, and ranges from 0 to 450mm. This is an Intimate area close to the body, within which it is possible to have physical touch, non verbal communication and emotional interactions. To gain such an intimate position one needs to be familiar with the other person or coerce. One has to ensure that by being in this zone, no harm occurs to the other person. Even in the intimate space close to the body, the nature and level of intimacy is affected by the attitudes of the persons involved. Here due to the intimate closeness one senses the texture, temperature, moisture, vibrations, energy, etc.

A handshake or hug nominally has no sexual meaning in many cultures. In some cultures privacy achieved by a veil is considered retardant of intimacy. Intimacy could be a display or an expression with physical touch but with no apparent mental feelings.

680px-albert_schrc3b6der_musikalische_unterhaltung_1885

Falling in Love by Albert Schroder (1854-1939)

■ Personal distance is useful for interactions between good friends, and family members and ranges 450mm to 1200mm. The area immediate to the body marks the Personal Area. It is a zone of regulated and selective participation. Here one can reach out through projection (expression), channels of communication, physically (through body limbs) or stretch out with gadgets (walking stick, stethoscope, etc.). The intimacy is regulated, but not a private affair. One may create screens to achieve it. One can dwell in a culture or state formed of metaphysical elements (beliefs, customs, etc.), to achieve the same.

In case of relationship with objects, declaration of ownership creates such personal space. The strong association to a person is imprinted on the object’s form or position. Chief guests chair, head chair at the end of a dining table are such personal entities.

Flight Delay

■ Social distance is for interactions between social acquaintances, and its range is from 1200mm to 3.5mt. This defines a zone of Nearness, where position and duration of the eye contact, sound pitch and olfactory sensation become important. This can be a non-committal area where personal involvement can be avoided.

As per the protocol, leaders of the two nations never share a seat, but rather occupy separate seats distanced with a small table or flower vase. Similarly deputies accompanying their leaders, are made to sit at some distance, from where they get a sense of participation but have no chance of intervention. On public platforms one intentionally uses lower sound pitch to draw attention. On very large dining table one can effectively hold conversation with members sitting on the two sides, but not across the table. In gatherings one uses differing sound pitch to reach desired distance.

■ Public distance is mainly for public spaces or non-personal interactions, and is above 3.5mt. These are Reach Zones beyond the anthropometric ambit. One may reach-out with additional reach tools, such as PA system, projection TV, surveillance camera, high pitch sound, extra ordinary (attention catching) movement, gaudy or unusual gesture, posture or dressing. Such zones constitute very specific spaces.

Temples have marked sanctimonious areas. Performance stages have podiums. In such zones intimacy or privacy of personal nature, are not available, yet one can announce it through metaphoric presentations.

Two persons or members of a group can talk in whispers and give out an impression of intimacy in spite of the apparent distance between them. Conversely talk-discussions in high pitch could be used to present bonhomie and thereby a close-knit entity. Politicians and celebrities talk in whispers to state things that need to be made public and talk loudly things that need not be public, both ways they draw the attention. A public orator changes the pitch from normal to very low or high to draw the attention of the audience and thereby register a point.

SPATIAL SEPARATION AND RELATIONS

Hall (1959) has stipulated that spatial separation also serves expansive function. He made a study of the spatial relations that seem appropriate to various kinds of interactions. They vary with intimacy, culture, and depend on the possibility of eye contact.

‘One can easily distinguish strangers from friends in an airport lounge. Strangers will keep a distance, taking alternate seats wherever possible. Friends tend to form clots, and families even pile one on the top of another. Total strangers will comfortably seat themselves only inches apart if the seats are back to back, but friends and the members of the family never arrange themselves in this way. Eye contact invites interaction and so is sought to the degree that intimacy already exists.’ (Hall E. T. 1959 The silent language).

 There are spatial zones appropriate to various types of interactions. Distances in virtual communication technology mediated interactions are likely to be different. Hall has also shown the cultural variations that South American needs much closer distance for impersonal information than a North American desire or is accustomed to.

Impersonal discussion, takes place at 1200 to 1500 mm, encroach the inner distance of this zone, and you or interlocutor will retreat. Move back from the outer distance and you can state what you wish to say by reducing the power of the interlocutor. One can move from impersonal discussion to a focussed or personal matter by reducing the distance. Alternatively change to a non committal mode by increasing the distance. TV anchors do these distance tricks on their show. For an intimate question the anchor pushes forward own body (Larry King of CNN ), but as soon as the question sinks in with the guest, the anchor withdraws not just to the nominal position, but little further backward. These distancing movements allow the guest to deliver the answer more objectively and the camera frames the guest alone for such a ‘heroic effort’. A host may intimidate the guest by doing exactly opposite of this. Smart elders and senior executives are (subconsciously) adapt to this.

PERSONAL SPACE for BEHAVIOUR

Post 589 by Gautam Shah (11 of 16 Behaviour in Spaces)

.

Behaviour in space is conditioned by two personal notions: Privacy and Intimacy. Privacy is personal as well as group-based requirement, whereas Intimacy is mostly an intra-personal or object affair. Behaviour first develops from the primary concern for survival, a defensive action where one tries to create a personal protective layer. It is also an offensive activity where people form groups to create a common protective mechanism, and thereby be more accessible to others. Here the privacy and intimacy become expressions of intra-personal relationships.

In a space, primarily, one tries to acquire a spot where privacy and intimacy are controllable. People discern their relationship with others in terms of distances or spaces between them. A personal space allows privacy and intimacy by controlling the distance from objects and people. Distance in space is simply a notion, a negotiable reach, one creates and perceives from other beings and objects. A personal space is an assurance for conducting certain tasks and expositions. The reach in space is negotiated by suitable space planning, physical and metaphorical declarations of the territorial ownership, style of space occupation and managing the extent and duration of exposure.

Perceived privacy in a public space > Wikipedia image

Privacy is a personal belief and is achieved by obscuring own self, or by isolating from people. One can obscure own self by merging with background or by becoming less perceptible. Isolation is achieved by barricading and distancing. A person or group achieves insulation through body posturing and adjust the exposure, control the communication, command the expression and re-calibrate the reach of the body and the sensorial perception. Privacy can help overcome many inhibitions through mental isolation. Psychological motivation helps one to ignore some of the side effects of lack of privacy.

Privacy provides the isolation whereas degree of interference by others determines the nature of intimacy. Both are important means for individualization or branding of unique personality. And whenever these are compromised one may try to adjust the posture, reorient the self and distance from others. In appropriate conditions it is easy to control ingress, distraction and unwanted participation by others.

One requires many different types of privacy:

● Physical and Social privacy: Ii is a function of distance and shielding. It is required against someone making a close approach (touch or near approximations). Social privacy is often equated to physical ‘crowding’ in a space. It is reflected in degrees of accessibility a person or group offers to others. The perceived territorial space gets crowded due to excessive or undesired social contact. Crowding means heightened accessibility or reduced interaction depending on the need for expression, communication, physiological requirements. Crowding affects the sense of belonging for group behaviour mechanisms (common purposes, beliefs). In ‘neighbourhood spaces’ one wants to be away from the closed interior space and so here crowding of any type takes away the social privacy.

Crowding may be tolerated if it is temporary (elevators, stairs, public transport) and for a definite purpose like for fun. The scale of a room it’s size relative to the occupants also influences conversational distance. As room scale reduces, people tend to sit closer together. Likewise, increased noise levels and distractions drive people to sit closer together.

 ● Visual privacy: Inherent in human behaviour is a tendency to avoid situations in which one can be watched without being aware of who is watching. Visual privacy addresses the ability to limit view of oneself by others. It can be achieved through the use of furnishings, furniture, amenities, partitions or walls.

In a private space or an office, people will often orient their desk in order to visually control the doorway and achieve a visually private space on one side of the desk. Similarly, people prefer to sit with a protected back, controlling the area they cannot see directly. In restaurants, the first seats to be filled are usually those along the walls. In outdoor spaces, people tend to sit against or beside objects such as trees and bushes rather than in the open. In open office plans’ a person is made to sit facing a wall or partition for lesser distraction from the back side passage, however, it is the unseen and unpredictable traffic on the backside that challenges the privacy. Contrary to this in garment stitching room workers are one behind the others and passage is on the side.

● Audio privacy: It is an insulation against being overheard, interference from background noise, and lack audio of clarity of listened sounds. A high quality of audio privacy significantly defines the level of communication, social interaction, and productivity. An appropriate relationship between the background noise and one that is produced within the activity space is conducive to speech privacy.

Complete insulation of a space, such as a study room, cuts-off the background noise, leading to loneliness or alienation. Hospital wards are hard finished due to issues of bacterial infections. The wards during daytime have high presence background noise that subdues or balances the noise from within the space. However, past midnight, in absence of background noise, the noise from inside the room becomes unbearable.

● Olfactory privacy This limits to reveal own physiological state or experiencing someone else such a state through hormones-odours. Other privacy parameters include the body temperature, breathing rate, heart beats, pulse rate, vibrations of the body, sweating and perspiration.

INTIMACY

Intimacy is a feeling of closeness or affinity between a person and another, or an object. Intimacy is also a biological need. Intimacy is considered a product of distance, and it relies on compatibility, sexual needs, glandular secretions, social acceptability, etc. It is an attitude, mental conditioning or mental posture. A person or group seeks privacy for security, to flourish in an environment. Intimacy could be one-way feeling that is without reciprocal feeling. One can be intimate with another person or group of persons without the apparent need for privacy. One can feel close to a person who is long dead –an illusory presence or through notional links (clothes, odours, recorded sounds, etc.). Distancing is also a matter of time, like remembrances. An intimate relationship is with a person, but an intimate space is one where an occupant and objects have intense relevance to each other.

Intimacy can have two main forms: emotional intimacy and physical intimacy. There could be other forms of empathy like cultural, intellectual, spiritual, social that are akin to intimacy in some conditions. Strategic relationship developed to take advantage of anyone could be very close but it is a make-believe intimacy.

A private abode is an own world. An intimate situation is safe, predictable and reassuring. Intimacy is like a domain where everything is under an exclusive command.

MICRO VENTILATION in Buildings

Post 588 by Gautam Shah

.

Micro ventilation is a very important passive method of adjusting heat and moisture for Hot-arid and Hot-humid climates. It is based on three factors: Air movements due to the differing pressures outside the building, like windward and wind-off sides. Buoyancy forces that results from temperature across the buildings interior and exteriors, and Pattern of circumstantial and designed apertures in the building shell. Micro ventilation relies more on external or macro conditions of the locality, but needs appropriate interior design.

Micro ventilation ensures that AIR enters or leaves a space through cracks, crevices, gaps or apertures, diluting the interior contaminants and adjusting the temperature and moisture. It is one of the easiest and consistent ways of managing comfort in enclosed and semi-open spaces. Micro ventilation systems are of vernacular design and time-tested solutions that have come down from one generation to another.

Entry and exit of air occur due to Differential Pressures along a point to point paths of air movement. The operative pressure is governed by both, the size and shape of the buildings layout scheme and individual characteristics of the building such as shape, size, height etc. Air movement occurs as a Buoyant Force due to the temperature difference across buildings’ interior and exteriors in general, and across the openings in particular. The air pressure is also affected by temperature of surfaces and surroundings, near the windward and wind-off sides. In a building micro openings are, circumstantial and designed. The micro openings are very much smaller in size in comparison to buildings’ formal openings like doors, windows, gaps etc. Micro openings yet have a characteristic size, shape, passage section, adjunct elements on internal and external faces, and their closeness to the location of need (for ventilation). The circulation or movement of air is affected, by the space profile (section), the task intensive volume and its datum, levels of ventilation (import-export) nodes, the hindrance by elements such as size and shape of external overhangs, the sill depth and its profile shape.

Micro ventilation operates as outside air has lesser moisture (except during actual raining conditions) then indoor air, so any level of ventilation, dilutes the interior humidity level and adds to the comfort.

Micro openings are circumstantial and designed, as casual parts of the buildings’ structure, components and systems (including openings), or formal or passive elements. But broadly these can be classified by their locations. Movement of air also encourages evaporation and increases cooling in the interior space. In dry arid climates smaller and deep-set openings create a strongly directional air movement allowing dwellers to locate their activities suitably. Deep-set openings also increase absorption of heat in the mass of the built-form or add simple cooling devices such as water wetted grass mats or fountains.

ROOF RELATED GAPS are such as in the thatched and country tile roofs, loosely laid roofs of slates, stone sheets. Formal devices include vents such as lattices, chutes, hoppers, etc.

GAPS IN UPPER SECTION OF WALLS are such as the unpacked ends of corrugated roofing sheets or terracotta tiles, ends of purlins and trusses when not sealed, and eyelets or oculi like holes in gables.

OTHER GAPS are circumstantial that exist in and around openings such as doors and windows, as loose joinery, leaky fitments, ajar shutters, door bottom space, peepholes, openings without shutters (gaps), latticed constructions such as of woven mats, fabrics, or louvered openings, crack or fissures in building elements, expansion joints, unsealed joints, etc.

Micro ventilation requirements inside a building vary depending on the climate, season of the year, use of the space, tasks, work-schedules, crowding in the space and presence of heat evolving means (hearths, machines, etc.) The ventilation requirements also depend on the amenities used for conducting the tasks.

In many old buildings the micro ventilation system is almost sufficient for dilution of fouled air. Micro ventilation of the building is further exploited by life style settings attuned to the air flow movement paths, pressure gradients and qualitative variations at different locations and time schedules. Task activities are continually shifted around to match the seasonal and diurnal variations.
