Perception of space – a function (f) of Space

Regional and Locational shift in Perception of space

“understanding
Space function and origin
Perception of space in terms of physical location of observer plays a crucial part in understanding planning of urban built form and is a vital part of Urban Planning, but the roots of such perception emerges from regional level. It is also related to conditioning, space perceived by residents of mountainous, hilly and undulating terrain are totally different from space perceived by person living in  flat terrain. Similarly space recognized by a person who spent most of his life in sprawling rural setting  can be totally different than a person living in an urban setting, It can be either” a not so pleasant shock” or “a surprise” or “an aspiration” for an individual while changing their location from hills to plain or rural to urban or vice versa. Usually what happens is that people constantly living in mountainous and hilly terrain witness only finite view due to restrained field of view by mountains,  hills and valleys, and when they occasionally come to plain and see that there is no limitation on the field of view, when they realize that they can see upto the horizon, it’s a pleasant shock to them.

Similarly when a resident of sprawling plain terrain goes for a vacation to some hill station or otherwise, they find it as a one of the finest moments of their life, primarily because of limited and ever changing field of view provided by hilly city,  they have a totally different experience of space that is finite which they have never experienced in life living in plains. Similarly a person living in a rural setting with sprawling, sparse and low-rise settlement when encounter with a city with medium to high-rise and dense built form and architecture, its not the rush of city that strikes him most, it’s the “Built Form” that strikes him dumb, he curiously looks out of the window of train and bus and cab, to see the buildings touching the sky, public spaces formed and enclosed by surrounding buildings. Suddenly he finds himself enclosed and restrained in the built form of the city which provides finite field of view with claustrophobic environment which is a paradigm shift in perception from the earlier experienced freedom of unlimited perceived space of rural setting. 

Perception of space – a function (f) of day and night

Dramatic shift in Perception of Space during Day and Night.

Day and Night, an ever existent inseparable phenomenon, it’s an external influence on the perception of space, architecture and built form, an environmental influence which alter the experience of space in dramatic way, but we pay very little attention on such a wonderful aspect of such powerful influence while planning an urban setting, or while designing interior of a building. 

In day sun light is ambient and almost omnipresent when it comes to outdoor urban setting with an interplay of light and shadow, but mostly the experience of any specific outdoor space is more or less uniform and little monotonous throughout the day, while night provides infinite possibilities to create, mould, play with space, volume and ambiance outdoor as well as indoors using variety of light sources. Volume of space is directly proportional to intensity of light source, sources of artificial light give a totally different perception on a dark night compared to day time since the space that we perceive and experience in night time. In this case the bright perceived space slowly merges into the  dark sphere of night. Hence night provides ample scope of creating user experience in an urban setting and its responsibility of planners, and architects  and landscape architects to plan and design lighting of public spaces as well interiors of a building with an aim to provide a unique experience of end use in night period. 

Perception of space – a function (f) of season


Seasonal variance in Perception of space

Technically there is unlimited space around us. Space in terms of perception is the space surrounding us in our field of view, what we are concerned here is the finite perceivable space by people which might vary as per surrounding built mass, undulating terrain, presence and intensity of light, environmental conditions, seasonal variation, etc. 

when it comes to seasonal variation it can be divided into primarily two parts winter and seasons other than winter. Winter provides a unique opportunity to experience a different kind of environment in terms of perceiving space around us which is because of presence of Fog and Mist, it is an exhilarating experience to walk in fog, or observing surrounding from window in winter during fog, it is so mysterious in its own sense, since the field of view is limited due to thick fog there is an element of surprise, you are curious to know and see what is beyond the visibility of fog, the same landscape that is dry and monotonous in summer is so attractive, versatile, ever-changing and inspirational  that you want to capture the that moment and view frame into your memory. This is all because winter provides perception of finite space, a limited field of view.

Pedestrian Vehicular conflict : why can’t we seem to find a solution?

By - Anoop Kumar Jha

Missing Human Behavioral Analysis aspect in Transport Simulation Model

No matter how functional and mathematically sound a transportation plan and related infrastructure design for any city or stretch appear before implementation, there is always a conflict between vehicular and pedestrian circulation which appears only once the transport plan is in place and functional, it’s the story of every city and every stretch. Blogs and forums are filled with discussions and captured photographs of such pedestrian vehicular conflicts.

It’s a conflict between pedestrians desire to take easiest and shortest route and transport planners age old scientific approach planning with modern simulation tools. Its conflict between “human desire” and “scientific approach”.  

In a country like India, apart from education and enforcement there is one missing crucial aspect which leads to pedestrian vehicular conflict in urban setting, that is understanding of human behavior and learning from past and other projects mistakes. It appears that common man collectively always appear smarter than the panel of planners, designers and implementation and enforcement agencies, because no matter how sound they make any system or transport plan people always find out loopholes in it. People are willing to take the dangerous shortcuts, break the law and even risk their life to reach the destination quickly. There is almost similar pattern and language of such human behavior across the cities and towns of India when it comes to intra city travel, but transport planners do not seem to observe and learn from such cases. Its high time that they should observe, document and incorporate human behavioral analysis in the transport simulation model to arrive at a successful transport plan for a city. 

Transport plan, systems and tools also need to be regionalized or localized, because what works in Bogota  or America or Europe might not work in Delhi or Surat or Jaisalmer  if replicated in-toto.

Containerized office buildings – how we have accepted it as a part of daily life!!

By - Anoop Jha


Actual Mechanical Ambiance Vs Desired Holistic Environment

Majority of contemporary so called modern office buildings and towers where people as employees spend almost half of their life lack a healthy ambiance, environment and micro-climate, though it might have cleared all the statutory requirements, might have followed all the guidelines, might have amazing interior finishes, decorated with beautiful and almost real plastic plants.

Some signs that you are working in a Containerized Office 

Lighting
Shear ignorance to natural light and view,
Sole dependence on Artificial lighting,
Absolute absence of task lighting concept,
Light glare and  shadow,
No correlation with time of the day 
Same ambiance every working-day/hour 

Climate control
No consideration for individual's temperature requirement
extra hot and cold pockets distributed over floor-space,
No correlation with indoor-outdoor weather

Other interesting Traits
Being watched for work-productivity in the name of security
Feeling isolated from outer world

There is urgent need to analyse and assess the existing office complexes across the region on different qualitative and quantitative parameters and come up with an exhaustive list of recommendations  can further be consolidated in a set of mandatory Architectural guidelines.

Some Recommendations to design a holistically habitable office complexes-

Breathing building skin and building envelop (Ideally like Human Skin)
Visually connected to outside world (gives pleasant view, correlate to weather or at least gives sense of time)
Day light linking (Saves energy as well) 
Task lighting as per sitting arrangement / furniture layout (prevents Light Glare and Shadow, and gives a sense of personal space) 
Accessible pleasant weather (let the pleasant light breeze come in, let them touch and hear the falling raindrops) 
Sensible Cooling & Heating with ability to personalize (increased productivity, less medical leaves)

Contemporary Architecture of India in flux


An observation on architectural character, practice, reason of flux, and control instruments     

There used to be a defined boundary of what is called “Contemporary Architecture” in every era since past few centuries, but the boundary of contemporary architecture at present, in the middle of first quarter of 21st century, has become a multi-domain experience with organic boundaries of different school of thoughts melting into each other. Earlier there used to be some set of rules and inspiration, material and climatic constraint, to govern and guide the aesthetic elements of localised architecture which in turn used to give defined architectural and urban design character to neighborhoods and city, but apparently we are losing that cohesiveness in contemporary urban fabric because there is no virtual or enforced control over the aesthetics of architecture at present In the developing countries like India, which is tissue of urban fabric. That does not imply that we want another Chandigarh, its for sure, we don’t want another Chandigarh by Le Cob., that is an old story, needs and lifestyle of people have changed, so the architecture and planning.

There are guidelines for the construction and execution but no rules or guidelines for architectural aesthetics, and its solely on the mercy and idiosyncrasy of either Clients who have their own idea of what contemporary architecture should be (i.e. they want their house to be either like the house of “Mr. X”, or more lavish and grand than “Mr. Y”, or exactly like the house featured in that architectural magazine “Z”) or it depends on majority of young architects for which its more about pressed necessity of earning bread & butter rather than using and  implementing the hard earned architectural knowledge , most of which are either victim of commercialization, crippled and forced to follow the market trends (which in fact doesn’t have any architectural  trend except copying from other contemporary developments or from history or from google image search results).  

If you inspect deeply you will realize that this apparent chaos of architectural design and aesthetics is actually nobody’s fault , at least not of any individual  because it was bound to happen and its all because of  technological advancement, which makes information and tools abundant. Architects as well as clients are immensely exposed to influences from all across the world due to free and unlimited information, architects  were never so free to  experiment with design and form of buildings due to computer modeling and simulation as well as unlimited possibility that structural design provides at present due to advance technology, equipments, material etc. There is no constraint of material, you have all the construction material at your disposal in any  part of the country, there is no architectural constraint of climate, because architecture has increasingly become active rather than passive,  you have all the equipments to control and maintain the indoor climate. But amidst all this, if the architecture and city planning need design guidelines, development control regulation, urban design guidelines or a separate nodal governing authority to maintain the aesthetic and cohesiveness of city, so be it.

Definition of “Per Capita Consumption” need to be modefied - Water Sector


By- Anoop Jha

Apparently “per capita consumption” figure is used in financials, estimates and projections of every project, and DPRs across the country and across the sectors, but apparently age old definition (Per Capita Demand in litres per day per head) and formula of “per capita consumption” seem to be flawed and vague. Let’s consider Water Sector for example.

There are few reasons for this apparently flawed 

First, this formula invariably assumes that all the water is being consumed at household, institutional or community level for some useful purpose, but that is not the fact. The fact is “the collective water losses at household and institutional level are huge in any given community, settlement, or housing society”, leaking taps, pipes due to “lack of maintenance and willingness to maintain” and water wastage related to casual behavior of users “due to lack of education and sense of responsibility”  are a regular phenomenon of almost every household. Planning bodies and Policy makers have to understand that unless they stop these water losses or unless they change the definition from  “Per capita Consumption” incorporating the water losses, there demand estimates, future projections, projects cost estimates, will inevitably  be vague and skewed,


Some interesting extract from the discussion on “India Water Portal” (indiawaterportal.org) on the similar subject are as follows-


“ When the norm for a large city is 250 lpcd, it doesn’t mean the residents actually get or use 250 lpcd. A large city has many other water needs such as public use in offices, railways stations, commercial places, for fire fighting, public horticulture, etc. All these are distributed over the population and indicated as per capita use” - Chetan Pandit
“The norms do not take in to account the climate. No distinction is made between Delhi that has a huge water requirement for desert coolers in summer and a bath twice a day is not a luxury; Pune that uses some coolers but not as common as Delhi and usually bath once a day is enough; and Copenhagen where the maximum summer temperature in 17 C and most of the time it is below 10 C” -Chetan Pandit

“Water consumption is affected by various factors which are variable and hence it is difficult to precisely assess the demand of public. There are empirical formulas available for estimating a fair value of domestic consumption for design of water supply systems. However, Indian Standard (BIS):1172-1993 is the basis of 135 litres/capita/day. This 135 litres/capita/person includes drinking (5 litres/capita/day), Cooking (5), Bathing (55), Washing of clothes (20), Washing of Utensils (10), Washing & Cleaning of house (10) and flushing of toilets (30 litres/capita/day)” - J.Harsha

Second, basis, thumbrules, lifestyle, requirement and related values for arriving at “standard per capita water consumption” in different urban areas changes in courses of time and cahnge as per seasonal variation which need to be accounted for calculation per standard water consumption” Standards need to be revised after a certain time interval.

“Details of present norms for water consumption are available in CPHEEO Manual on Water Supply and Treatment and Per capita water supply in selected urban centers of India is available at Water Supply, Sanitation and Solid Waste Management in Urban Areas by National Institute of Urban Affairs, 2005”

Third, accuracy of standard per capita water consumption figure is directly proportional to the size of sample (no. of household) surveyed, which may vary from agency to agency which prepares the report. Larger the sample more realistic the results would be. There should be Policy norms for minimum size of sample to be surveyed and heterogeneity of the sample.
