Demonstration and Deployment Team

The Center for Building Energy Science (formerly Building 661)

The Center for Building Energy Science is an innovative example of the type of advanced energy retrofits that are needed throughout the region and the country. The intent is to demonstrate how integrated design and construction methods can result in the cost-effective reduction of building energy use by at least 30 percent.

Divided into three separate programmatic zones – with appropriate integrated mechanical systems applied in each – the building functions as a living laboratory to showcase multiple energy saving technologies, with built-in monitoring and verification strategies for testing and performing energy efficiency research. Monitoring is critical to demonstrate performance, validate energy models, and provide case studies for industry-wide adoption.

Integrated Energy Efficient Design and Delivery

The integrated design and delivery process serves as an example for industry to follow. This process includes establishing a new and different governance structure to guide the project, and a collaborative team that works together to make decisions for the design of the buildings. The EEB Hub facilitated a meeting of building stakeholders – including owner, occupant, architect, construction management, and contractor representatives – to collectively identify project values in a pre-design workshop. The workshop concluded that the project values should include collaboration, learning, performance, predictability, and certainty, among others. Successive decisions were made using the filter of the accepted project values. This process increases quality and efficiency, decreases waste, and fosters greater collaboration among stakeholders.

Energy Efficiency Measures

The Center for Building Energy Science features exposed mechanical and lighting approaches, real time monitoring, and public education spaces. Energy efficiency measures include:

• Passive and active chilled beams serving large public spaces and workrooms
• Under floor air delivery with displacement diffusers serving the second floor high-occupancy spaces
• Variable refrigerant volume system serving the first floor offices
• Dedicated outdoor air (DOA) unit with exhaust air energy recovery (enthalpy wheels)
• Demand controlled ventilation
• High efficiency condensing hot water boiler
• Heat recovery chiller providing regenerative heating and reheat during cooling season
• Automatic lighting controls in all non-utility spaces, vacancy/occupancy control in enclosed spaces, and time of day controls in common areas
• High efficiency LED lighting
• Optimal levels of spray foam insulation added to walls (R-value 24) and roof (R-value 30) to reduce heat loss
• New double glazed low-emissivity (low-e) argon-filled units with thermally broken frames to replace existing windows, with higher performance glazing on the south facing windows and skylights
• Manual interior shades below skylight
• Trees on east and south side of the building to prevent glare and to act as exterior shade
• Reduced overall lighting power by approximately 8.5% below ASHRAE 90.1-2007 baseline
