تغییر وضعیت انرژی در ساختمان های تجاری در هند تحت سناریو های سیاست های جایگزین

The total electricity consumption from commercial sector was about 9% during 2013–14 in India. Load research survey was carried out to study the usage patterns for all types of electric appliances used in commercial establishments at income, appliance and end-use levels in Gujarat state of India – one of the most progressive states. Penetration level of efficient appliances, electricity load curves and Energy Performance Index (EPI) were estimated. The mean EPI was 98 kWh/m2/year (SD = 105.5) for surveyed small commercial establishments (low income) while mean EPI was 181 kWh/m2/year (SD = 68) for surveyed large commercial establishments (Malls). Electricity saving potentials was estimated if electric appliances at these commercial establishments were replaced with efficient appliances. Four alternate scenarios were analyzed using cost of conserved energy (CCE) curves with various efficiency enhancement options – following at least commercial sub-category level median EPIs, following average EU equivalent EPI levels, following average EPI levels of equivalent US commercial establishments, and following the best available technologies (BAT). The average energy savings ranged between 14% and 25% across buildings and scenarios. Energy efficient air-conditioner and LED lights offer the highest energy savings potential among appliances.
