ANNOUNCEMENTS
Building sector is one of the most energy-intensive sector and there is a need to reduce the energy consumption in this sector. There are many initiatives taken by the government to reduce the number down to a permissible limit. Out of which, development of Energy Conservation Building Code (ECBC) was one of the major steps taken by Government of India (GOI). To comply with ECBC 2007, three different cases were analysed in this report namely, present case, baseline case, proposed case. Initially, present case is compared with baseline case which shows negative saving in the energy consumption. Now, to get saving or to comply the building with ECBC 2007 certain ECMs are applied over the present case. The impact of each ECM on the present case is analysed. After the application of these ECMs, energy saving is observed.
In this report, work is done on a commercial building in Chennai (consisting of Office space, Retail area, Gymnasium) for compliance with ECBC 2007. Building energy model is prepared and simulation is done in eQUEST. Proposed case (made with help of selected ECMs) is then compared with present case and baseline to analyse the energy saving and to comply the building with ECBC 2007.
From the analysis, it is found that present case is consuming 2,747 MWh/year more than the baseline case. Furthermore, proposed case which is made with the application of ECMs over the present case, energy saving of around 16% is achieved over the baseline case, which is in compliance with ECBC 2007. The proposed case, when compared with the present design, gives energy saving of approximately 20%. The HVAC part of the building contributes 52% of the total saving and lighting part of the building contributes 48% of the saving.
