Delivering budget-driven, high-performing, low-energy buildings requires deliberate practiced attention to critical aspects of design and construction throughout the developmental process. At every stage, from initial programming to design to construction phase review, opportunities exist to simultaneously improve design aesthetics, reduce cost, improve performance and mitigate risk. The Chesapeake Bay Foundation’s Brock Environmental Center embraces the International Living Future Institute’s Living Building Challenge standard by aiming to be a net-zero water, net-zero waste, and net-zero energy building.
Energy modeling performed by Baumann Consulting provided critical feedback to the project team at every stage of design development. Precise evaluation of the interaction between the building enclosure and natural lighting strategies, quantification of natural ventilation benefits, and feedback on the specification and selection of mechanical equipment contributed to a 37% energy use decrease from 100% DDs to CDs with a 106% overall reduction in site energy consumption compared to the ASHRAE 90.1 baseline. Baumann’s services contributed to the overall goal of achieving an annual energy use of no more than 190,000 kBtu and an energy use intensity (EUI) of around 20 kBtu/ft² even prior to the inclusion of renewable energy through wind turbines and photovoltaic panels.
