| Abstract: | Due to the increasing rate of urbanization, in many towns of Himachal Pradesh in India, the building energy-footprint is increasing day by day. Hence, in this present study Energy Performance Index (EPI) of the traditional rural and modern urban houses located in and around Mandi – Sundernagar towns at Himachal Pradesh, India, having composite climate, are assessed based on the household energy consumption data for the year 2021 and 2022. The EPI plays a pivotal role as an indicator to assess the energy efficiency of different kind of buildings by setting up a practical holistic benchmark for building designers and other professionals to reduce and optimize the operating energy footprint of the buildings. Further, the effects and correlations of various influencing factors on the annual household energy consumption and EPI are also analyzed through regression analysis to develop empirical models for the prediction of future trend of household energy consumption pattern and EPI of the houses. The calculated average EPI value of modern houses is found as 39.24 kWh/m²/year (range: 29.43–50.53 kWh/m²/year). In contrast, average EPI value of traditional houses is calculated as 7.89 kWh/m²/year (range: 6.34–10.36 kWh/m²/year). The study shows that the mean total annual energy consumption of modern houses is 5.4 times higher than that of the traditional houses; the mean EPI of modern houses is 5 times higher than that of the traditional houses; and the mean EPI/person of modern houses is 5 times higher than that of the traditional houses in the study area. It is also observed from the comparative analysis that in the modern houses, monthly energy consumptions, EPI and EPI/person are higher than the traditional houses especially during winter and summer months due to the different construction practices. Linear multiple regression analysis has shown that total annual household energy consumption and EPI can be well predicted by the factors – floor area, annual average household income, and total number of different appliances.
