Efficiency Details

Henley Hall is a 50,000 square foot building that contains 17 labs, 20 faculty members and 100+ Graduate students. The energy efficient features of this building include:

Passive

•    Optimized building envelope properties to minimize mechanical cooling and heating
•    Thermal insulation properties significantly superior to the minimum requirements of California Energy Code
•    High performance glazing with low solar heat gain coefficients and good visible light transmittance
•    Solar shading
•    Free cooling will be provided to the building via operable windows, which will naturally ventilate the offices and student workspaces

Active

•    Demand controlled ventilation (DCV) in the Lecture Hall to allow the system to only supply enough minimum fresh air to meet the current demand
•    Aircuity system in the wet labs that allows the system to provide fresh air as it is needed based on sensed room air quality
•    Cooling tower as a water-side economizer, enabling cooling tower condenser water to be dedicated to chilled beam free cooling operation
•     Minimization of reheat within the labs through the application of chilled beams, demand controlled ventilation using air quality sensing, and dynamic reset of the lab ventilation supply temperature
•    Ventilation heat recovery from Dry Labs DOAS exhaust air stream
•    High efficiency condensing boilers
•    Daylighting design and daylight dimming system
•    25% reduction in lighting power density and advanced controls

Renewables

•    Rooftop Solar PV (under consideration)

Sustainability

•    Rapidly renewable and regional materials emphasized in material selection
•    Over 20% recycled material used to construct project
•    At least 75% construction waste diversion specified
•    Reclaimed water for toilet flushing and make-up water for the cooling tower
•    Low flow fixtures including dual flush toilets and 1 pint urinals
•    Storm water design quality and quantity control
•    Monitoring collaboration with IEE researchers to marshal the data of IEE as an exemplar energy use case
•    Planning to make building solar panels ready for a possible lease plan strategy
