68 Sustainable Public Procurement: Towards a low carbon economy onwards. 43 Such an incentive based mechanism has a great potential for acting as an enabling tool for internalising energy efficiency within the procurement process. Fig. 4.1 Sample Energy Star Labelling Green Building Practices Green building practices refers to the practice of bringing efficiency within the way in which buildings use resources such as energy, water and materials. Such efficient use can be a result of better planning, design, choice of site, construction, operation, maintenance, and removal throughout the complete building life cycle and can be instrumental in reducing building impacts on human health, environment and overall carbon foot print of the organization functioning out of that building. Therefore, green buildings are built with the objective of meeting one or more of the following: Reduced Operating Costs Improved Public and Occupant health 43 Ministry of Power notification.

69 Sustainable Public Procurement: Towards a low carbon economy Reduced Environmental Impact 44 Reduction of operating costs is key as until and unless a practice is sustainable economically, there is no incentive to adopt or switch to such practices. Energy efficiency, therefore, is a rational choice as not only does it make the practitioners more environmentally responsible and at a reduced threat from environmental pollutants but also brings down their energy expenditure by following sustainable consumption. However, there are several impediments to adoption of energy efficiency in building practices such as builders incurring initial cost but not enjoying the benefits, hence the first cost bias exists very strongly. There is also a lack of availability of efficient products, equipment testing and certification and energy expertise. 45 However, in recent times, there has been a realisation of the potential of practising sustainable building practices and its role in reducing the operational costs. Rating systems to facilitate and support an objective evaluation and differentiation of buildings based on their energy efficiency have also come up. The potential of energy savings in residential and commercial buildings is stated below 46 – 30% savings in energy could come through energy efficient residential building o In this 15% savings could come from proper orientation, fenestration, shading, roof and wall insulation o 5% savings could come from energy efficient internal lighting o 10% savings could come from the use of solar eater heating 40% savings in energy could come through energy efficient commercial buildings o In this 10% energy savings could come from proper orientation, fenestration, shading, roof and wall insulation, efficient glazing o 15% energy savings could take place from energy efficient internal lighting 44 Louisiana CleanTech Network (2008) URL http://www.lacleantech.net/green_building.htm 45 Mathur, Ajay (2006) Current Status of Energy Efficiency Building Codes in India.
