Our team provided full MEP and Sustainable Design services including CFD modelling. The Classed as the best NZE design of 2013 the ZNE design process begins with the optimization of onsite renewable energy. The building footprint is optimized to maximize roof area for solar thermal and photovoltaic solar panels. In order to match the actual building consumption to the energy budget provided by this system a variety of passive strategies were developed.

 

Analysis of local climate data revealed that a steady ocean breeze could be utilized for ventilation. The front façade is extended above roof level to create a continuous wind chimney. Prevailing breezes create negative pressure behind the façade where louvers draw air through the main spaces from windows at the opposite end of the building. Additionally, skylights automatically open to support airflow. A radiant floor system connected to rooftop solar thermal panels provides heating and cooling.

 

These passive strategies are coordinated by a building management system that is tied to a roof top weather station. The BMS can thereby switch modes from natural ventilation to full cooling for comfort control. There is no additional HVAC system in the facility.
