Building Technology Showcase: Systems and Features
Fraunhofer Center for Sustainable Energy Systems
The Building Blocks of Energy Efficiency
The Building Technology Showcase is a deep energy retrofit of a historic building, incorporating a variety of energy-efficient systems, materials and measures to create significant reductions in whole-building energy consumption.
A building management system (BMS) provided by Siemens can monitor and control all functional components of the Showcase to optimize economy, efficiency, and comfort. Additional support is provided by a continuous commissioning system from Cimetrics that monitors performance and energy consumption, then uses this information to identify potential issues or create recommendations for efficiency improvements.
Heating, Cooling, and Ventilation (HVAC)
The Showcase saves energy by reducing heating and cooling loads and using more energy-efficient HVAC systems. Installed features include:
- Chilled beams and radiant chilled panels (Price HVAC)
- Displacement ventilation (Price HVAC)
- Coof roof membrane (Cooley Group)
- Variable frequency drives (Taco, Yaskawa)
- Energy-efficient chiller systems (Multistack)
- Radiant baseboards (Smiths)
The Showcase uses a combination of energy-saving LEDs and natural daylighting. The majority of the building uses LED products donated by Philips, including a Color Kinetic system installed in the building's exhibit space. Additional LED products have been provided by TerraLUX and Digital Lumens.
The efficiency of the building's lighting systems is further enhanced by use of dedicated lighting controllers donated by OSRAM.
The building features a ThyssenKrupp synergy elevator driven by a gearless motor. In addition to being more efficient than a conventional model, regenerative braking technology allows the elevator to generate electricity while in use.
Other features in the building include:
- Solar control glass (Guardian)
- Automated shading control (Hunter Douglas)
- Phase change material insulation (DuPont)
- Vacuum insulation panels (VIPs) (Dow Corning)
- Formaldehyde-absorbing drywall (CertainTeed)
- Sustainable rubber flooring (nora)
- Countertops made from recycled glass (Merrimack Stone)
