Green Infrastructure (GI) and Low-Impact Development (LID) rainwater management strategies improve upon the conventional approach for rainwater management by

replicating a site's natural hydrology
discharging rainwater at a faster rate
increasing a site's impervious surface
providing a greater volume of rainwater detention

Answer(s): A

Explanation:

Green Infrastructure (GI) and Low-Impact Development (LID) rainwater management strategies improve upon the conventional approach for rainwater management by replicating a site's natural hydrology. GI and LID are design approaches that use various practices to mimic the natural water cycle and reduce the negative impacts of development on the environment. They aim to preserve, restore, or create natural features that can capture, infiltrate, evaporate, or reuse rainwater on site, rather than conveying it to a centralized stormwater system. By doing so, they can reduce runoff volume and peak flow, improve water quality, enhance groundwater recharge, increase biodiversity, and create more attractive and resilient landscapes. Therefore, option A is the correct answer. The other options are not true for GI and LID strategies. Discharging rainwater at a faster rate (option B) would increase the risk of flooding, erosion, and pollution downstream. Increasing a site's impervious surface (option C) would reduce the infiltration and evaporation of rainwater and increase runoff and heat island effects. Providing a greater volume of rainwater detention (option D) would not necessarily improve the site's hydrology, as detention is only a temporary storage of rainwater that does not address the runoff quality or quantity issues. For more information on GI and LID rainwater management strategies, you can refer to the LEED v4 Reference Guide for Building Design and Construction or the Green CE course on Rainwater Management for LEED v4.1 Projects.

QUESTION: 138

During a design charrette, community neighbors raise a concern about potential glare resulting from a project's highly reflective roof.
Which option should the LEED AP recommend to best address these concerns?

Install a vegetative roofing system
Change the design to reduce the amount of roofing area
Change the roofing material to a dark material to eliminate the issue
Increase the parapet height

Answer(s): A

Explanation:

Installing a vegetative roofing system is the best option to address the potential glare resulting from a project's highly reflective roof. A vegetative roofing system, also known as a green roof, is a roof that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. A vegetative roofing system can reduce the reflectivity of the roof surface and mitigate the glare impact on the surrounding environment. It can also provide other benefits, such as reducing heat island effects, improving stormwater management, enhancing biodiversity, and increasing roof insulation. Therefore, option A is the correct answer. The other options are not as effective or desirable as installing a vegetative roofing system. Changing the design to reduce the amount of roofing area (option B) may not be feasible or desirable, as it may compromise the project's program or performance. Changing the roofing material to a dark material to eliminate the issue (option C) may reduce the glare, but it will also increase the heat absorption and emission of the roof, contributing to heat island effects and increasing cooling loads. Increasing the parapet height (option D) may block some of the glare, but it will also increase the material and construction costs, and it may not be sufficient to prevent glare from all angles. For more information on vegetative roofing systems and their benefits, you can refer to the LEED v4 Reference Guide for Building Design and Construction1 or the Green Roofs for Healthy Cities website.

QUESTION: 139

Which of the following products must always be included in Materials and Resources credits?

Faucets
Furniture
Interior Paint
Fire suppression system

Answer(s): C

Explanation:

Interior paint must always be included in Materials and Resources credits. This is because interior paint is considered as a permanently installed product, which is defined by the LEED v4 Reference Guide for Building Design and Construction as "a product that is installed in a project permanently or semi-permanently, such that removal would require demolition or substantial renovation."1 Permanently installed products must be included in the calculations for the following Materials and Resources credits: Building Life-Cycle Impact Reduction, Building Product Disclosure and Optimization - Environmental Product Declarations, Building Product Disclosure and Optimization - Sourcing of Raw Materials, and Building Product Disclosure and Optimization - Material Ingredients.1 The other options are not always included in Materials and Resources credits. Faucets (option A) and fire suppression systems (option D) are considered as mechanical, electrical, and plumbing components, which are excluded from the scope of Materials and Resources credits unless they are specifically addressed by the credit requirements.1 Furniture (option B) is considered as a non- permanently installed product, which is optional to include in Materials and Resources credits, except for the Building Product Disclosure and Optimization - Material Ingredients credit, where furniture must be included if it is within the project scope.1

QUESTION: 140

According to the Integrative Process Credit, Integrative Process, the goal-setting workshop should identify

potential project sites
targeted LEED credits
expected water demand
expected energy demand

Answer(s): B

Explanation:

According to the Integrative Process Credit, Integrative Process, the goal-setting workshop should identify targeted LEED credits. This is because the goal-setting workshop is a meeting that involves the project owner and key project team members to establish the project's sustainability goals, design objectives, and performance targets. One of the outcomes of the workshop is to identify the LEED credits that are relevant and achievable for the project, based on the project scope, budget, schedule, and site conditions. Therefore, option B is the correct answer. The other options are not the objectives of the goal-setting workshop. Potential project sites (option A) are usually determined before the goal-setting workshop, as they affect the project's feasibility and design. Expected water demand (option C) and expected energy demand (option D) are not identified in the goal-setting workshop, but rather in the preliminary water budget and the preliminary energy modeling, which are part of the analysis phase that follows the goal-setting workshop. For more information on the Integrative Process Credit, Integrative Process, you can refer to the LEED v4 Reference Guide for Building Design and Construction or the Projectific blog post on LEED Integrative Process Credit Explained.
