The Wadhwa Residence
The primary aim of the project was to reduce the dependence on artificial lighting and mechanical systems to achieve human visual and thermal comfort respectively without compromising the basic requirements and necessities of the occupants in all the habitable space. The analysis included daylight and energy simulations with and without blinds to optimize the glazing unit to fulfill the client’s requirement. The analysis helped to freeze the envelope design so that heat load calculation can be done to specify the type of HVAC system required in the building. The next step includes study at the building level, understanding the daylighting performance of the building through manual calculation using daylight thumb rules and impact of daylight as heat gain. Further, expanding the analysis using daylighting simulations. The next step includes optimizing the HVAC system identified by the MEP Consultants and enhancing the system specification, features & efficiency considering the thermal analysis of the building based on the materials selected for construction. The consumption of different end uses applicable for the residence such as HVAC, Lighting and Equipment were estimated.
Ecofirst Services Limited desired to support the client, architects and MEP consultants in integrating sustainability concepts in Samarpan, The Wadhwa Residence. The type of analysis undertaken by Ecofirst helped to identify the site potential, carry daylight analysis to freeze the envelope, select appropriate HVAC system and carry out thermal analysis to analyze the performance of the building with the goal of further optimizing it.
