Description: Bureau of Energy Efficiency, Government of India, initiated energy conservation building codes (ECBCs) in 2007 to enhance building energy efficiency in the country. ECBC, 2017, for commercial buildings and Eco-Niwas Samhita, 2018, (Part-1) for residential buildings are the latest codes introduced. Anticipating the enormous potential of energy savings in the energy-intensive urban residences, the present study attempts to assess the energy performance of typical high-rise residential apartments in the warm-humid climate of Kolkata following implementation of envelope norms specified in these codes through whole building energy simulation. Energy performance index for total and cooling energy of four code compliant design cases is compared with the actual conventional design showing significant improvement (7.88–25.57% and 11.35–36.34%, respectively). Statistical association of each of the compliance parameters is studied showing a strong correlation of the indices with residential envelope transmittance value, roof thermal transmittance and visible light transmittance. The uncertainty in the variables influencing energy performance is probed into sensitivity analyses. Solar heat gain coefficient of the non-north window glazing is found to influence the residential envelope transmittance value and thus the cooling and overall energy consumption most, demanding special attention during material selection.
