Question
Which permanently installed building products are addressed in the Materials and Resources Credit category calculation?
A. Framing
B. Elevators
C. Process equipment
D. Formwork for concrete
Answer
A. Framing
Explanation
The Materials and Resources Credit category calculation addresses the permanently installed building products that are part of the building’s structure, enclosure, and interior elements. These include framing, flooring, insulation, windows, doors, interior walls, ceilings, and finishes. Process equipment, elevators, furniture, and formwork for concrete are not included in the calculation.
The LEED Materials and Resources (MR) credit category addresses the environmental impacts of the materials and products used in a building. The MR credits aim to reduce the quantity of materials used, select more sustainable materials, and minimize construction waste.
When calculating MR credit points, only permanently installed building products are included. Permanent building products are those that become an integral part of the completed structure. Key examples of permanently installed products that would be included in MR credit calculations are:
Structural framing (steel, wood, concrete, etc.)
- Insulation
- Drywall and interior sheathing
- Roofing materials
- Doors and windows
- Flooring (carpet, tile, hardwood, etc.)
- Cabinetry and countertops
- Electrical wiring and lighting fixtures
- HVAC ductwork and equipment
Elevators (B), while permanently installed, are considered transportation equipment rather than building products. Process equipment (C) refers to specialty equipment used for manufacturing or industrial processes housed within a building, not the building itself. Concrete formwork (D) is temporary and removed after the concrete cures, so it is not a permanent part of the finished building.
In summary, structural framing and other integral components that remain as part of the completed building are the permanently installed products included when calculating LEED MR credits. Temporary construction materials and non-building specialty equipment are excluded from these calculations.
