Clark County Building Design Sustainability Requirements and Incentives for New Developments

The purpose of Sec. 30.04.05(J) is to support implementation of the Clark County Sustainability and Climate Action Plan by ensuring that developments conserve water and energy resources, improve air quality, reduce urban heat island effect, and help Clark County adapt to future climate challenges. New multi-family residential development must achieve at least 5 points from the sustainability measures. New nonresidential development must achieve at least 7 points from the sustainability measures.

Incentives for sustainability measures are provided beyond 1.5 times the minimum requirement and include:
(a) Required parking reduction of up to 10%, which may be combined with the reduction received under §30.04.04F.1.i, for a possible 20% reduction, with the maximum parking limitation based on the cumulative reduction.
(b) Density increases of up to 10%.
(c) Building height increases of up to 10%.

Sec. 30.04.05(J)(4) Building and Site Design Sustainability Options
Points to meet sustainability measures are awarded when:
1. project installs cool roofs with SRIs equal to or greater than 78 for low-sloped roofs or (<2:12) or 29 for steep-sloped roofs (>2:12).
2. orienting all roof surfaces 30 degrees of true east-west direction and either flat or sloped in southern direction.
3. providing shade structures for at least 50% of all south- and west-facing windows and doors.
4. providing shade structures such as awnings or arcades for sidewalks or buildings adjacent amenity zones.
5. providing shaded walkways along building facades.
6. use of daylighting strategies to minimize use of artificial lighting.
7. multi-family residential developments use floor-to-ceiling height of 9ft to facilitate natural ventilation and 11ft for nonresidential developments.
8. use of low-emissivity glass on all south and west-facing windows.
9. providing shading above all building entrances and ADA ramps.
10. 70% percent of total roof area contains solar panels.
on-site solar panels are installed to generate 100% of project’s estimated annual electricity use.
11. battery backup is proved to run critical loads to offset peak grid demand.
