According to the LEED v4 Reference Guide for Building Design and Construction, the project team must conduct a waste stream audit to identify the top five recyclable waste streams generated by the building and its occupants. The audit must cover a representative time period of a minimum of 24 hours, and must account for variations in the type and quantity of waste generated by different building uses and operations. The project team must then provide dedicated areas for the collection and storage of these materials for recycling.
The project team must also provide dedicated areas for the collection and storage of batteries, mercury- containing lamps, and electronic waste, or demonstrate that a local program is in place to properly dispose of these materials.

During the design phase documentation submission, the Materials and Resources (MR) Credit: Building Product Disclosure and Optimization - Environmental Product Declarations (EPDs) is reviewed. This credit encourages project teams to select products from manufacturers who provide transparency about their products' environmental impacts. EPDs are often part of the design documentation, as they influence material selection and project sustainability goals. Other PBT source reduction credits or raw material sourcing credits are typically more relevant in later phases, as they may involve construction processes and materials procurement rather than initial design specifications.

Explanation
A benefit of earning Regional Priority credits is that the LEED project can achieve more sustainable outcomes by recognizing the issues that are a priority in the project's location. Regional Priority credits are not new LEED credits, but instead are existing credits that USGBC regional councils and chapters have designated as being particularly important for their areas1. The incentive to achieve the credits is in the form of a bonus point. If an RP base credit is earned, then a bonus point is awarded to the project's total points1. This way, the project can address the geographically specific environmental, social equity and public health priorities of its location2. References:

This is because:
A building automation system (BAS) is a system that controls and monitors various aspects of a building's operation, such as lighting, heating, ventilation, air conditioning, security, fire alarm, and energy management1.
A BAS can allow programmable load control (PLC), which is the ability to adjust the power consumption of devices or equipment based on a schedule, a sensor, or an event2. PLC can help reduce the energy demand and cost of a building by optimizing the use of resources and avoiding unnecessary or wasteful consumption3.
The LEED AP BD+C V4 credit for Demand Response requires that buildings have a demand response program that can respond to changes in electricity prices or supply by reducing or shifting the demand for electricity4. A BAS can enable such a program by allowing PLC and other features that can modulate the power usage of devices or equipment in response to market signals or internal conditions.
Therefore, installing a BAS to allow PLC can help achieve the Energy and Atmosphere Credit for Demand Response by reducing the energy demand and cost of a building.

Explanation
The Materials and Resources Credit, Building Life-Cycle Impact Reduction, rewards projects that reuse existing building structures and envelopes, or salvage materials from off-site or on-site sources. According to the LEED v4 Reference Guide for Building Design and Construction, the project team must calculate the percentage of building being reused by dividing the area of the existing building structure and envelope that is reused by the total area of the completed building structure and envelope1. However, the project team must exclude from the calculation any hazardous materials that are remediated as a part of the project, such as asbestos, lead, mold, or PCBs1. Therefore, the asbestos containing materials found on the perimeter walls will be excluded from the calculation, regardless of the volume.
