In May 2007, the Ministry of Power launched Energy Conservation Building Code(ECBC) for its adoption on a voluntary basis in building with a connected load of 500KW or greater or a contract demand of 600KVA or greater. In this context, it is important for the building designers to understand and utilize energy simulation programs to satisfy ECBC compliance requirements. Technological advancements in computer software have provided several tools that can help the designers to predict and analyze the energy performance of a building with good accuracy and with substantial reduction in effort. Such programs allow for sensitivity analysis of various design options and decisions—from the conceptual and schematic phases to the detailed specification of building components and systems.
Energy Simulation is a computer-based analytical process that helps building owners and designer to evaluate the energy performance of a building and make it more energy efficient by making necessary modification in the design before the building is constructed.
The computer based energy simulation programs model the thermal, visual, ventilation and other energy-consuming process taking place with in the building to predict its energy performance.
The simulation program takes into account the building geometry and orientation, building material being used, building facade design and characteristics weather parameters indoor environmental conditions, occupant activities and schedules, HVAC and lighting system.
Energy simulation is a computer-based analytical process that helps building owners and designers to evaluate the energy performance of a building and make it more energy efficient by making necessary modifications in the design before the building is constructed. Use of energy simulation software is necessary to show compliance with Indian Energy Conservation Building Code (ECBC) via “Whole Building Performance Method.”
