This is a 7-storey high-rise new construction office building.
A Water Source Heat Pump (WSHP) system was chosen and designed for this multi-tenant office building to provide a high comfort level, flexibility and high thermal efficiency.
To increase the thermal efficiency even further and to minimize the utility cost (gas and electric bills), the following design ideas were implemented:
• Condensing boilers for WSHP loop heat injection;
• A multi-stage fluid cooler for WSHP loop heat rejection;
• A heat recovery unit for the building ventilation system that exchanges the energy between the outdoor air and the exhaust air of the building.
Project completed in 2011.
