Abstract: This paper assesses the impact of internal loads and operational pattern of a mixed-mode building on its thermal comfort, heating and cooling energy consumptions. The study deals with an office building with a built-up area of 1280 m located in composite climate of India (29.9 N and 77.9E). The building was modelled and simulated using Energy Plus software tool. Significant internal thermal loads and operational strategies were identified based on a sensitivity study. Internal thermal mass contributed by furnishings and upholstery, volume of internal spaces and the type of lighting were found to have a significant impact on heating and cooling energy. With respect to operational patterns variable thermostat settings based on adaptive comfort criteria, dynamic window operations and the use of lighting controls were found to have a significant impact. A prototypical office space in the building was selected for detailed analysis. Parametric simulation studies were carried out and the impact of these factors on comfort and energy consumption was estimated. Based on these findings strategies for reducing the heating and cooling energy consumption were evolved. Findings from the prototype evaluation were applied to the whole building and results pertaining to improvement in comfort and reduction in energy consumption have been presented. © 2016 NCEUB.
