How this relates to strategies for greening buildings…

LEED Categories

RNV-12

Sustainable Sites - Stormwater Management

RNV-13

Where buildings are located near water sources it is important to mitigate the effects of stormwater runoff and parking lot pollution.

Stormwater Runoff and Parking Lot Pollution

Pervious pavers. Pervious pavers installed in the parking lot to allow stormwater to percolate into the ground and insure that stormwater runoff volumes are/were the same as “predevelopment levels.”

RNV-14

RNV-15

You can create detention ponds to capture runoff.

Detention Ponds and Underground Separation Tanks

Underground separation tanks can be installed to filter sand and oil from stormwater prior to its release into the city’s stormwater system.

RNV-16

Energy and Atmosphere

RNV-17

Goal: Minimize energy used for heating, cooling and lighting.

Summer. In the summer a night flush vent system replaces the hot air of the day with cool night time air.

RNV-18

Radiant heat system. A radiant heat system using the highest efficiency commercial boilers and ceiling mounted radiant panels is used to warm buildings on cold days.

RNV-19

Ceiling mounted radiant panels is used to warm buildings on cold days.

R30 insulation in the roof.

RNV-20

R12 insulation in the walls retain heat in the winter and keep buildings cool in the summer

Roof mounted sky lights and smoke vents provide natural light to the interior and workspace.

RNV-21

Photo sensors and motion detectors are used to shut off lights when area lighting is not necessary.

RNV-22

What percent of the building materials used will be made of recycled sources?

Materials and Resources

RNV-23

Recycled materials in walls and floors. Concrete with recycled content flyash for walls and floors.

See www.greenbuilder.com/sourcebook/Flyash.html

Interior columns and roof structures. Recycled steel for interior columns and roof structures.

RNV-24

Use local materials. Distance from building site. How far were materials shipped from? X% of the building materials and products used were manufactured within 500 miles of the construction site.

X% of the construction materials derived from within 500 miles of the construction.

RNV-25

FSC certified wood. Nearly 100% of the wood used in construction was FSC certified — meaning that it was certified as sustainable by the Forest Stewardship Council.

Low or No VOC finishes and carpets. The finishes and carpets contained low or no VOCs with no urea formaldehyde resins.

RNV-26

Construction waste. 75% of the construction waste was recycled or salvaged.

RNV-28

Buyer’s Decision-Making Cycle

!  The factor driving the transition from one phase to the next is “performance oversupply”.
