North Las Vegas Green Building Sustainability Options

The purpose of the North Las Vegas Code of Ordinances § 17.24.140 is to promote sustainable development. Developments are recommended to follow certain sustainable site and building design options to promote the design and construction of energy efficient buildings; encourage on-site renewable energy production; reduce air, water, and land pollution from energy consumption; and reduce the urban heat island effect.

Design features related to energy and green building designs include:
1. installing a “cool roof” or green vegetated roof on all buildings.
a. Cool roofs shall have a Solar Reflectance Index of 50 or greater, with points awarded. Base solar reflectance code requirements are in Section 17.24.140.D Alternative Energy System Standards.
b. Green or vegetated roofs shall include vegetation on at least 50 percent of the roof area of all buildings in the project (25 percent for renovated buildings), and shall use only drought-tolerant landscaping, with points awarded. Regulations for calculating open space credit for green roofs are in Section 17.24.020 Open Space and Parks.
Incentive: Any building that installs a roof meeting the requirements of this option shall be eligible for a floor-area bonus of 1.5 times the allowable gross floor area of the roof or an increase in height of one story over the maximum allowable height. If the roof open space is open to the public, the density/height bonus shall be doubled.
2. installing a radiant technology barrier in roof.
