Abstract: Achieving Energy Efficiency in Office Buildings plays a key role in reducing the Environmental Impact of Buildings to a larger extent. The Users in the workplace are often affected by the improper design of HVAC systems. In most of the office buildings the Indoor Environmental conditions were not designed, controlled and maintained which in turn increases the Energy cost of the buildings. Sustainable Design of HVAC Systems includes all the mechanical equipments that efficiently controls, monitors and supplies the Indoor Air. The objective of this paper is to (i) Do a comparative study and analyses the various building Envelope in office buildings for reducing the Energy Cost in designing HVAC systems in Office buildings using Ecotect Modelling.(ii) To compare the Energy cost of Water Cooled Screw Chillers and VRF Systems. The above experimentation was held in ELCOT S office building in salem. The findings of this paper revealed that usage of Porotherm wall construction along with VRF SYSTEMS in office buildings found to be effective in achieving sustainable HVAC design.

Keywords: Energy Efficient Building Envelope, HVAC, Water Chiller, VRF(Variable Refrigerant Flow).
Scope of the Article: Control and Automation
