Engineering Innovation Hub - LEED TBD

The Engineering Innovation Hub is anticipated to be a LEED building at the Silver or Gold level and includes the following sustainable dimensions:

Mechanical Systems

The HVAC system is set-up to operate and react to the building occupants by reading CO2 levels in the highly occupied spaces.  The supply air volume to each space is to reduced when spaces are partially occupied or unoccupied.  This is controlled through a building Direct Digital Control (DDC) system. In addition, energy recovery is provided on the exhaust air stream; sensible and latent energy is recaptured from the conditioned exhaust air stream and is used to preconditioned the incoming outdoor air.  High-efficiency motors are used for HVAC equipment along with variable frequency drives. This all reduces the energy demands on the building. 

Electrical and Lighting Systems

Energy savings over standard building construction are obtained through the use of efficient LED lighting fixtures, automated lighting controls including occupancy sensing to turn off light fixtures when the spaces are not used and daylight sensor to dim the light fixtures when the sun is enough to brighten each space. Individual lighting controls for shared multi-occupant spaces have also been provided. Although a centralized power monitoring system is incorporated into the design, the circuit breakers in the main switchboard have internal metering components, and real-time metering data can be accessed through an electronic metering system on the main switchboard.

Envelope Design

Beyond mechanical and electrical systems, the building envelope was intended to be highly insulated and airtight, as part of a passive design strategy.  The envelope characteristics exceed the code minimum requirements for energy efficiency and help to lower seasonal heating and cooling requirements.

In keeping with thermal efficiency goals, the window to wall ratio was kept low at 21% of the envelope.  Windows and curtain walls have a U value of 0.28 (compared to code U-0.35), and have low e coated Solarban 70XL insulated glass with SHGC of 0.27 (compared to code SHGB-0.40).  The low U-factor and SHGC translate into less heat transfer into and out of the building along with less solar gain allowed into the building, each of which reduces seasonal heating and cooling requirements.

The exterior wall assembly has an R-value of 28.2 and is a thermally broken rain screen system comprised of interior gypsum board, 6” studs filled with 6” batt insulation, Densglass sheathing, Blueskin air and moisture barrier, and an exterior steel Z-girt system holding Rockwool semi-rigid insulation and Ultra High-Performance Concrete Panels.  A layer of 2” thick rigid insulation board continues behind the perimeter case stone base, extending down to the foundation footing to provide an R-10 barrier. These values exceed the wall insulation R-value = 12.5 CI minimum.

The roof assembly for occupied portions of the building has an average R-value of 31.71, and consists of concrete slab on metal deck with rigid insulation tapered from 2” to 8”, and cover board.  Over this, a TPO White membrane roofing is used to minimize solar heat gain and reduce heat island effect. 

Heat Island Effect

The building has a high reflective roof, reducing the heat island effect.

Rainwater Management

The site that the Engineering Innovation Hub now sits used to be a parking lot with a 90% impervious rate.  The site is now 45% impervious by adding a rain garden.  and The new bio-retention area / rain garden collects rainwater that falls on the roof and portions of the site.  Rainwater that flows into the bio-retention area seeps over time into the ground reducing the impact of the development on surrounding systems during peak rain events.

Water Management

The bathrooms include water-efficient toilets, urinals, and faucets.  The project does not include permanent irrigation for plantings.


Only native plants were selected for the site.

Construction Waste Management

Approximately 75% of construction materials were recycled from this project.

Sustainable Building Materials & Low-Emitting Materials

Over 10% of building materials include recycled content.  14% of building materials were procured regionally, supporting regional economic development.  All adhesives, sealants, paints, coatings, flooring systems, and wood and agrifiber products are made from low-emitting materials.

Indoor Air Quality & Ventilation

The mechanical systems provide increased ventilation of fresh air to indoor spaces, at least 30% above ASHRAE Standard 62.1-2007.
