energy use and user satisfaction
« on: October 31, 2004, 11:53:36 PM »
With low energy design gaining prominence in the Indian context what are the issues concerning a greater acceptability of energy efficient design practice in the country?  Besides developing awareness and expertise in the field is there need for a change in attitude on part of end user as well? One of the primary purposes of energy use in buildings is to meet requirements of ‘comfort’ for occupants that occupy them. ‘Comfort’, which is essentially a state of mind. A matter of perception and expectation. With the corporate air-conditioned office mushrooming all over metropolitan India, is the end user of these spaces satisfied with his environment? What constitutes satisfaction? Do people inherently prefer air-conditioned or naturally ventilated environments? Or  have they come have a certain level of expectation from their work environment and the ventilation system thereof? What sort of expectations would the end-user have from a mixed mode system that switched between air conditioning and natural ventilation as he pleased?

Any thoughts on these issues?

Almost 50 % of the total operational energy consumption of a building goes into cooling. With the availability of refrigeration, air conditioning and an economical energy supply, we seem to have forgotten passive cooling techniques and designs that have been used sice ages, be it the subterranean or rock cut architecture, dence low rise form with white lime plaster in Rajasthan, Fountains and channels in Moorish architecture or wind towers in Iran. Although we seem to have abandoned this integrative art of building and living it is not too late to revert back to such techniques. That is before we deplete all energy reserves and degrade our environment to the extreme.

The question is how satisfied would people be in such environments. A lot of research is now going into adapting some of these passive strategies for modern day use and meeting the requirements set by standards. But it still remains, that unless people are more acceptable to adopting these technologies, high energy systems will always be more prevelant. The idea is not to force a substandard system on the occupants, but to identify what constitutes comfort and aim to satisfy this requirement rather than any established standard. It has been observed by some reaearch done in the west that people inherently prefer a natural environment and the associated fresh air, views to the outside, personal controllability etc.. Do you think this would apply to the indian case as well, say for example if we have environments that are passively conditioned and moderate any extreme environmental conditions?
