Nanticoke Hall features solar panels using an "evacuated tube" water heating system and a 20,000-gallon cistern to collect rainwater for landscape irrigation.
The renovations at Pocomoke, Manokin Wicomico and Nanticoke halls were designed and constructed in accordance with LEED gold certification requirements.
The renovations were performed to extend the life cycle of existing building stock, conserve resources, retain cultural resources, reduce waste and reduce environmental impacts of new buildings as they relate to materials manufacturing and transport.
A LEED-accredited professional supported and encouraged the design integration required for a green building project, and streamlined the application and certification process.
Pollution from construction activities was reduced by controlling soil erosion, waterway sedimentation and airborne dust generation.
Development of inappropriate sites was avoided and the environmental impact was reduced by enhancing buildings already on a site.
Development to urban areas was channeled with existing infrastructure to protect greenfields and preserve habitat and natural resources.
To reduce pollution and land development impacts from automobile use, the project encourages alternative transportation via public transportation and providing bicycle storage.
Existing natural areas were conserved and damaged areas were restored to provide habitat and promote biodiversity.
The roofs are designed to reduce heat islands (thermal gradient differences between developed and undeveloped areas), minimizing the impact on microclimate and human and wildlife habitat.
Light pollution is reduced by minimizing light trespass from the building and site, reducing sky-glow to increase night sky access, improving nighttime visibility through glare reduction, and reducing development impact on nocturnal environments.
Water efficiency is maximized within buildings to reduce the burden on municipal water supply and wastewater systems.
The building's energy-related systems are verified to be installed, be calibrated and perform according to the owner's project requirements, basis of design and construction documents.
Geothermal heating and cooling was incorporated into the design for Manokin, Wicomico and Nanticoke using a closed loop design and geothermal heat pumps.
Geothermal heat provides domestic hot water for Manokin and Wicomico; Nanticoke uses a roof-mounted solar hot water heater.
The minimum level of energy efficiency performance for the building and systems are established.
Attic mounted energy recovery units provide all fresh make-up air to building.
Fundamental refrigerant management is utilized to reduce ozone depletion.
Increasing levels of energy performance above the baseline in the prerequisite standard are achieved to reduce environmental and economic impacts associated with excessive energy use.
The commissioning process began early during the design process and additional activities were executed after systems' performance verification was completed.
Recyclables are collected to facilitate the reduction of waste generated by building occupants that is hauled to and disposed of in landfills.
Construction waste was managed to divert construction, demolition and land-clearing debris from disposal in landfills and incinerators. Recyclable recovered resources were redirected back to the manufacturing process. Reusable materials were redirected to appropriate sites.
The renovations used materials with 20 percent recycled content (post-consumer and half pre-consumer) to increase demand for building products that incorporate recycled content materials, thereby reducing the impacts resulting from extraction and processing of virgin materials.
The renovations used regional materials to increase demand for building materials and products that are extracted and manufactured within the region, thereby supporting the use of indigenous resources and reducing the environmental impacts resulting from transportation.
Certified wood was used to encourage environmentally responsible forest management.
Minimum indoor air quality (IAQ) performance was established to enhance indoor air quality in buildings, thus contributing to the comfort and well being of the occupants.
Outdoor air delivery monitoring provides capacity for ventilation system monitoring to help sustain occupant comfort and well-being.
Additional outdoor air ventilation improves indoor air quality for improved occupant comfort, wellbeing and productivity.
Both during and after construction, an IAQ management plan reduced indoor air quality problems resulting from the construction/renovation process in order to help sustain the comfort and well-being of construction workers and building occupants.
Contractors used low-emitting materials (e.g., adhesives and sealants, paints and coatings, carpet systems) to reduce the quantity of indoor air contaminants that were odorous, irritating and/or harmful to the comfort and well being of installers and occupants.
A high level of lighting system control by individual occupants or by specific groups in multi-occupant spaces (i.e. classrooms or conference areas) promotes the productivity, comfort and well-being of building occupants.
A comfortable thermal environment supports the productivity and well-being of building occupants.
The assessment of building thermal comfort over time is performed.
Green housekeeping and integrated pest management are performed. An interactive Energy Dashboard display and monitoring system with LCD screen is located in main entrance area to promote education and outreach.
