To what specific LEED credits can parking structures provide value when pursuing certification?*

SUSTAINABLE SITES

• Sustainable Sites c1 (Site Selection) – Avoid constructing the parking facility on prime farmland, habitat for threatened or endangered species, public parkland and other areas deemed an “inappropriate site” by the USGBC.

• Sustainable Sites c2 (Development Density and Community Connectivity) - Construct the facility on a previously developed site AND in a community with a minimum density of 60,000 square feet.

• Sustainable Sites c3 (Brownfield Redevelopment) – Construct on the parking facility on a site documented as contaminated OR on a designated brownfield.

• Sustainable Sites c4.1 (Alternative Transportation – Public Transportation Access) – Locate the parking facility near public transportation, giving patrons the option to park their vehicle once and utilize transit rather than driving to numerous destinations.

• Sustainable Sites c4.2 (Alternative Transportation – Bicycle Storage and Changing Rooms) – Include space for convenient bicycle storage within the facility, as well as conditioned space for showering and changing rooms.

• Sustainable Sites c4.3 (Alternative Transportation – Low-Emitting and Fuel-Efficient Vehicles) – Provide preferred parking spaces for 5% of the total parking capacity in the facility OR provide a 20% or more parking rate discount for patrons driving low-emitting and fuel-efficient vehicles

• Sustainable Sites c5.1 (Site Development: Protect or Restore Habitat) – Precast parking structures allow for the precaster to deliver the structural components as they are needed, helping to minimize site impact/disturbance.
(ONLY Applicable to P/C structure)

• Sustainable Sites c6.1 (Stormwater Design – Quantity Control) – Implement a stormwater management plan to limit disruption of the surrounding site, as well as reduce or eliminate pollution from stormwater and contaminants.

• Sustainable Sites c6.2 (Stormwater Design – Quality Control) – Implement a stormwater management plan to limit disruption and pollution of natural water flows by managing stormwater runoff.

• Sustainable Sites c7.1 – 7.2 (Heat Island Effect, Non Roof and Roof) – Light colored concrete for walls and roofs help to minimize heat island effect. Low emissivity and High Albedo (Solar Reflectance)

• Sustainable Sites c8 (Light Pollution Reduction) – Utilize screening to minimize light trespass from the building, reducing sky-glow as well as impacts on the surrounding development.

WATER EFFICIENCY

• Water Efficiency c1 (Water Efficient Landscaping) – Limit or eliminate the use of potable water or other water on or near the project site for landscape irrigation.

• Water Efficiency c2 (Water Efficient Landscaping) – Employ strategies to limit or eliminate the use of potable water used in mixed-use spaces.

• Water Efficiency c3 (Water Use Reduction) – Employ strategies to further increase water efficiency within the mixed-use spaces to reduce the burden on municipal water supply and wastewater systems.

ENERGY AND ATMOSPHERE
The natural thermal mass properties of concrete make precast structures less reliant on other means of insulation and temperature control:

• Energy and Atmosphere c1 (Optimize Energy Performance) – The thermal mass of precast concrete used to construct parking facilities regulates peak temperatures by helping the space to remain cooler during the summer and warmer during the winter. This also helps to reduce the loading on a heating and cooling system for mixed-use spaces, which in turn lowers total energy consumption.
(ONLY Applicable to P/C structure)

• Energy and Atmosphere c2 (On-Site Renewable Energy) – Parking structures can utilize on-site renewable energy features including but not limited to solar photovoltaic, wind power, bio-fuels, co-generation, and hydrogen fuel cells.

MATERIALS & RESOURCES

• Materials & Resources c2.1 - 2.2 (Construction Waste Management) – The off-site production of precast concrete eliminates on-site construction waste and optimizes in-plant material use.
(ONLY Applicable to P/C structure)

• Materials & Resources c4.1 – 4.2 (Recycled Content) – Parking facilities which utilize precast concrete use a number of recycled products, including recycled steel reinforcement, fly ash, and blast-furnace slag.
(ONLY Applicable to P/C structure)

• Materials & Resources c5.1 – 5.2 (Local/Regional Materials) – Parking structures are constructed primarily of concrete. Most concrete components consist of local materials, and typically travel less than 200 miles to the site.

INDOOR ENVIRONMENTAL QUALITY

• Indoor Environmental Quality c3.1 (Construction Indoor Air Quality Management Plan – During Construction) –Precast concrete utilized in precast parking structures does not off-gas or support mold growth. Its precise manufacturing results in tight joints, virtually eliminating the intrusion of external dust, allergens and pollutants.
(ONLY Applicable to P/C structure)

• Indoor Environmental Quality c4.1 (Low-Emitting Materials – Adhesives and Sealants) – The mixed-use areas of a parking facility can utilize low-emitting adhesives and sealants during the installation of carpets, floors, etc.

• Indoor Environmental Quality c4.2 (Low-Emitting Materials – Paints and Coatings) – The mixed-use areas of a parking facility can utilize low-emitting paints and coatings when painting the interior occupied spaces.

• Indoor Environmental Quality c4.3 (Low-Emitting Materials – Flooring Systems) – The mixed-use areas of a parking facility can utilize low-emitting flooring systems within the interior occupied spaces.

• Indoor Environmental Quality c5 (Indoor Chemical and Pollutant Source Control) – Parking facilities can install systems to minimize the control and entry of pollutants into the occupied spaces within the building.

• Indoor Environmental Quality c6.1 (Controllability of Systems - Lighting) – Utilizing photocell receptors, timers and computerized controllers and/or dimmers will reduce the use of light within the parking facility.
