LEED Silver Certificate & Plaque Presented to USPS
On Thursday, June 30th, Gray Construction presented the LEED® Silver certificate and plaque to USPS for the St. Paul Processing & Distribution Center (P&DC) in Eagan, Minn. The 611,538 s.f. facility was an expansion to the existing Bulk Mail Center and was designed and constructed in two consecutive phases over a 770 day schedule. Although not part of the original project requirements, the customer requested that Gray pursue LEED certification when the overall project was approximately 50% complete. Following that request, Gray adjusted the design and construction plans to accommodate the requirements associated with LEED certification. The USPS St. Paul P&DC is a continuation of the 16+ years between Gray and USPS.
Elements of sustainable construction incorporated into the facility include:
- Brownfield redevelopment.
- Native landscaping that does not require irrigation.
- Preferred parking for fuel efficient vehicles, low-emitting vehicles, and carpools; proximity to public transportation and community services.
- Over 40,000 tons of existing pavements were crushed and processed on-site to provide aggregate base for use under new pavements.
- Light pollution reduction & heat island reduction.
- Energy efficient building system that exceeds ASHRAE 90.1 requirements by 30%.
- No CFC based refrigerants.
- Enhanced commissioning of building systems.
- Over 70% of on-site generated construction waste was diverted from landfills through the use of recycling.
- Over 20% of the total building materials content, by value, was manufactured using recycled materials.
- Over 40% of the total building materials content, by value, was comprised of materials and products extracted, harvested or recovered, as well as manufactured within 500 miles of the project site.
- Outdoor air delivery monitoring.
- Low-emitting adhesives, sealants, paints, coatings, carpets, and composite wood products were utilized to reduce the quantity of indoor air contaminants.
- Indoor Chemical & Pollutant Source Control.
- Individual and networked lighting controls.
- Energy Control & Management System for HVAC systems.
- The electrical switchgear rooms are ventilated using excess air from the workroom allowing for increased ventilation in the workroom and eliminating overheating in the penthouse without adding mechanical cooling.
- Vertical storing dock levelers are utilized allowing full sealing at enclosed platform doors reducing air infiltration when the dock doors are closed.
