A vegetated roof primarily contributes to the Sustainable Sites (SS) Credit: Heat Island Reduction. Green roofs reduce the heat island effect by minimizing roof surface temperatures through vegetation, which absorbs less heat than conventional roofing materials. This helps lower building cooling costs and mitigates urban heat effects. Sensitive Land Protection (B) and Site Assessment (C) are unrelated to roof treatments, while Light Pollution Reduction (D) deals with exterior lighting strategies.

This option allows the project team to evaluate the impact of different window-to-wall ratios on the energy performance of the building, and to optimize the design accordingly. A simple box energy model is a preliminary analysis tool that can be used to compare different design alternatives and inform decision making in the early stages of the project12.

This factor is included in the lamp lumen uplight calculation, because it represents the amount of light that is emitted downward by the fixture, which does not contribute to light pollution1. The lamp lumen uplight calculation is used to determine the percentage of total luminaire lumens emitted above horizontal, which must not exceed the maximum allowed values for each lighting zone2.

According to the LEED v4: Building Design + Construction Guide, lead, mercury, copper and cadmium are examples of persistent bioaccumulative toxins (PBTs) that should be limited in building products. PBTs are substances that remain in the environment for long periods of time, accumulate in living organisms, and pose health risks to humans and wildlife. One of the prerequisites for the Materials and Resources Credit, Building Product Disclosure and Optimization - Material Ingredients, is to reduce the use of products that contain PBTs above certain thresholds1. References: LEED v4: Building Design + Construction Guide, Materials and Resources Credit, Building Product Disclosure and Optimization - Material Ingredients, Option 3: Product Manufacturer Supply Chain Optimization1
