Colour It Green By: Abhinav kumar
Existing buildings can be made green by efficient utilisation of water and light and using other energy-saving methods, says Dr Prem C Jain
With concern for environment degradation and threat of global warming looming large, the common man has become more conscious of his contribution to the issue.
Buildings, one of the major contributors to energy consumption, provide great potential to reduce an individual's carbon footprint.
Existing buildings can be made green by making various renovation/ alterations to the building structure, replacing equipment and changing human behaviour. Installing more efficient lighting and using natural daylight, using water-efficient fixtures like low-flush toilets and by adding environmentally friendly finishes and furnishings also help. It may be possible in some cases to upgrade the building envelope by providing under deck and external wall insulation.
The focus of the green building movement in India is currently on new buildings and various organisations like the Indian Green Building Council (IGBC) and The Energy and Resources Institute are likely to also actively promote green renovation of existing buildings. One has to take the case of UK into account. Huge existing housing stock there is a large consumer of energy. In India, we are witnessing more people going green every year and this trend is likely to escalate in the coming years with a move towards affordable s green buildings.
The green building movement has also been focused on office buildings and we are already seeing the inclusion of a variety of building typologies, including airports, exhibition centres and hospitals.
Green building concepts focus on handling of consumer waste, water efficiency, reduction in fossil fuel use in commuting, energy efficiency and conserving natural resources leading to enhanced occupant health, happiness and well-being. As stated earlier, making various renovation/ alterations to buildings, using natural light, installing water-efficient fixtures and also making behavioral changes to make reuse and recycling of materials and avoiding wastage of energy by being energy conscious, will accomplish the objective.
