Meeting net zero with simulation
In order to reach the net zero energy target set by the living building challenge the Brock Environmental Center at Chesapeake Bay VA required significant energy, daylight and natural ventilation simulation.
The designers had a goal of an EUI of 20 kBtu/ft, the envelope was optimized, natural daylighting utilized and natural ventilation strategies evaluated. Once these initial evaluations were completed, three mechanical systems were modelled and evaluated. The final HVAC system was modelled and the feed back was used to help with the selection of components for the system.
The building used exterior insulation, daylight sensors, an occupant controlled natural ventilation system along with a dedicated outdoor air system with heat exchanger and VRV system. The electricity required was provided through an onsite wind turbine and solar panels. The building achieved 106% energy savings over the ASHRAE 90.1 2007 baseline and has been certified platinum.
