USGBC LEED-AP-BD+C - LEED AP Building Design + Construction (LEED AP BD+C)

Temporary wood products cannot be included in the calculations for the Materials and Resources Credit, Building Disclosure and Optimization - Sourcing of Raw Materials, Option 2. Leadership Extraction Practices. This is because the credit only applies to permanently installed building products, not to products purchased for temporary use on the project1. The other options are false. If any temporary wood materials are included in the calculation, they must be excluded from the total value of permanently installed building products1. Non-certified wood materials do not contribute to other credits, unless they meet other criteria such as recycled content or regional materials2. FSC-certified wood materials purchased for more than one project cannot be applied to other projects seeking LEED certification, unless they are reused or salvaged materials3.

Revise the documentation and resubmit the form

If a project receives a review comment and technical advice on a prerequisite, it means that the documentation submitted was incomplete, inaccurate, or unclear, and that the project team needs to address the issues raised by the reviewer and provide additional information or clarification. The project team should revise the documentation and resubmit the form as part of the final review to demonstrate compliance with the prerequisite requirements. Abandoning meeting this prerequisite is not an option, as prerequisites are mandatory for LEED certification. Submitting an appeal to Green Business Certification Inc. is only applicable if the project team disagrees with the reviewer’s decision or interpretation, and has additional evidence or arguments to support their claim. Asking the General Contractor to be more aggressive with recycling goals is not relevant to this prerequisite, as it does not address the documentation issue.

For the building to receive one point for Location and Transportation Credit, Green Vehicles, the rate for green vehicles must be 80% less than the regular parking rate. Therefore, if the discounted parking rate is $450 per month, the rate for green vehicles must be $90 per month (20% of $450).

Providing an educational program on the environmental and human health benefits of green building practices is a potential innovation strategy that is not addressed by any existing LEED credit. It also meets the criteria of being measurable, replicable, and having a positive impact on the project and the environment.

The document that details ideas, concepts, and criteria that are essential for a building's success is the Owner's Project Requirements (OPR). The OPR outlines the goals, expectations, and criteria from the owner’s perspective, setting a foundational vision for the project. It is used in LEED AP ID+C certification as a guideline for aligning design and construction decisions with the owner's objectives. The Basis of Design (BOD) then takes the OPR’s high-level goals and translates them into technical requirements. Both documents support integrated project delivery by helping ensure design aligns with the owner's goals, but the OPR specifically details what the owner considers essential.

The credit may be achieved by using nonroof measures only, such as shading, paving, and vegetation, to reduce the heat island effect on the site. The credit does not require a highly reflective roof for all projects, but allows for flexibility and trade-offs depending on the climate and design conditions. The project can use the Heat Island Reduction 1 to demonstrate compliance with the credit requirements. The credit is feasible and applicable for this project, and does not need an alternative compliance path.

This option requires the project to classify wood derived fuel as a recycled material that contributes towards the credit, because it is a waste material that is converted into a useful energy source1. Wood derived fuel can be used for heating, electricity generation, or co-firing with other fuels2. According to the LEED v4: Building Design + Construction Guide, recycled materials are those that have been reprocessed or remanufactured from recovered materials3.

Incorporating precipitation sensors with smart irrigation controllers (C) maximizes irrigation efficiency by adjusting water usage according to real-time weather data and soil moisture levels, reducing unnecessary irrigation during rainfall. This LEED strategy helps conserve water and supports the Water Efficiency (WE) Credit: Outdoor Water Use Reduction. Fixed rates (A), timers (B), and overlapping sprinkler heads (D) do not optimize water based on environmental conditions, leading to possible water waste.

The renewable energy option is economically feasible if the present value of the utility cost savings over the lifetime of the system is greater than or equal to the present value of the higher initial cost of the system. This means that the system will pay for itself and generate net savings in the long run. The utility cost savings depend on the amount of energy produced by the solar thermal panel, the price of natural gas, and the inflation rate. The higher initial cost depends on the size, type, and installation of the solar thermal panel.

The LEED Platinum certification requires the project to achieve exemplary performance in at least one credit that allows it, as specified in the LEED Reference Guide1. One of the credits that meets this criterion is the Indoor Environmental Quality Credit, which focuses on providing healthy and comfortable indoor environments for occupants. The credit has two options: Quality Views and Enhanced Commissioning. Quality Views requires the project to have windows that provide views of natural scenery or water bodies, which can enhance the well-being and satisfaction of occupants. Enhanced Commissioning requires the project to have a comprehensive commissioning plan that ensures all systems are properly installed, tested, and operated before occupancy. Both options can help reduce energy consumption, improve indoor air quality, and create a positive sensory experience for occupants.
