LEED-AP-BD+C Exam Dumps : LEED AP Building Design + Construction (LEED AP BD+C)

The Integrative Process credit under the LEED BD+C v4 rating system encourages the coordination of all the project team members, starting from the predesign phase, to discover unique opportunities for project design, enhanced building performance, and green features. The three phases within the Integrative Process Credit are:

Discovery phase: This involves investigating at least two energy-related and several water-related sustainable design strategies prior to the end of schematic design 1 .

Design and Construction (implementation) phase: This requires the project teams to turn their findings into reality 2 .

Occupance, Operations, and Performance Feedback phase: This phase involves the evaluation of the implemented strategies and their effectiveness 3 .

The percentage of recycled content contributing to the credit is calculated based on the value of the recycled content relative to the total construction cost. The combined value of recycled content here is $1 million (post-consumer) + $1 million (pre-consumer) = $2 million. The percentage is then calculated as:

2,000,00010,000,000×100=20%\frac{2,000,000}{10,000,000} \times 100 = 20\%10,000,0002,000,000​×100=20%

Therefore, the recycled content accounts for 20% of the total material value for the project, contributing to the Materials and Resources Credit: Building Product Disclosure and Optimization - Sourcing of Raw Materials .

Adding a concrete walkway will increase the site’s impervious cover, which is the percentage of the site area that does not allow water to infiltrate into the ground 1 . Impervious cover can affect the site’s stormwater management, heat island effect, and habitat quality. The project team should consider using permeable paving materials, vegetated roofs, or rain gardens to reduce the impervious cover and mitigate its impacts 2 . The other options are not directly impacted by adding a concrete walkway. Project density calculations are based on the floor area ratio and the number of occupants, not the site features 3 . Erosion and sediment control plan during construction is required for any site disturbance, regardless of the type of material used 4 . Air quality as a result of off gassing that occurs as concrete cures is not a significant issue for outdoor applications, and can be minimized by using low-emitting concrete products 5 .
