The Integrative Process credit requires the project teams to perform analyses for both energy- and water-related systems from the predesign phase to the design and construction phase. The project teams should also identify and use opportunities to achieve synergies across disciplines and building systems.

This option allows the project to comply with the minimum energy performance prerequisite by following the prescriptive recommendations of the ASHRAE 50% Advanced Energy Design Guide (AEDG) for the applicable building type and climate zone1. This option simplifies the decision making and analysis process by providing clear and specific guidance on how to achieve 50% energy savings compared to the baseline standard2. This option also reduces the need for energy modeling and documentation, which can save time and money for the project3.

The bonus location valuation factor in several Materials and Resources credits under LEED AP BD+C V4 is intended to incentivize the purchase of products that support the local economy. Products extracted, manufactured, and produced within 100 miles (161 km) of the project are valued at 200% of their cost within the calculations1. This adds value to locally produced products and materials2.

When calculating the reverberation time of a room, the operating sound level of the nearest HVAC equipment is the least relevant piece of information. The reverberation time is the time it takes for the sound to decay by 60 decibels after the source stops emitting sound. The reverberation time depends on the volume and the surface area of the room, as well as the sound absorption coefficients of the materials that cover the surfaces. The height and width of the room are needed to calculate the volume and the surface area. The noise reduction coefficient of the ceiling surface and the sound absorption coefficient of the floor surface are needed to calculate the total sound absorption of the room. The operating sound level of the nearest HVAC equipment is not relevant for calculating the reverberation time, but it may affect the background noise level and the speech intelligibility in the room.
