Summary
Newark's Green Building, Sustainability, and Resiliency Standards ask developers seeking subdivision or site plan approval to specify a high-reflectance 'cool roof' with a minimum Solar Reflectance Index of 82 initial and 64 aged, or a vegetative green roof, to cut rooftop heat absorption citywide.
§ 41:16-13-2. Roof Design. 1. Specify a high-reflectance roof (cool roof). High-reflectance low-sloped roofs should have an initial Solar Reflectance Index (SRI) of at least 82 and an aged SRI of at least 64. Steep sloped roofs with pitches greater than 2:12 should have an initial SRI of 39 and an aged SRI of 32. 2. Specify a vegetative roof (green roof) using native or adaptive plant species.

Full Breakdown
Chapter 41:16-13, adopted by Ordinance No. ' Section 41:16-13-2, Roof Design, gives two paths: a high-reflectance low-sloped roof with an initial Solar Reflectance Index (SRI) of at least 82 and an aged SRI of at least 64, or, for steep-sloped roofs pitched greater than 2:12, an initial SRI of at least 39 and an aged SRI of at least 32; alternatively, a developer may specify a vegetative 'green roof' planted with native or adaptive species. 4, applied by the Central Planning Board during development review rather than enforced as a Construction Code mandate, so existing roofs carry no retrofit obligation.
The same chapter addresses open space, water conservation, energy use, materials/waste management, and indoor environmental quality, all under the same 'to the extent feasible' standard, distinguishing this section from the mandatory 'shall' language used elsewhere in Chapter 41:16, such as the bird-friendly glazing rule at § 41:16-12.
Violations & Fines
Because § 41:16-13-2 uses 'should' rather than 'shall,' the Central Planning Board treats a missing cool-roof or green-roof specification as a design deficiency to address during subdivision or site plan review, not as a code violation subject to a fine. Reviewers can request plan revisions or supporting documentation before granting approval, but the section itself carries no separate monetary penalty.
