This is again, the same principle as MRc1.1 and MRc1.2, however instead of reusing structural elements, the requirement is geared towards reusing interior walls, doors, floor coverings and ceiling systems.
Same as MRc1.1, except increase the amount required from 75% to 95%.
Intent: Reduce the amount of building materials necessary for a building by reusing the existing materials.
Requirement: Reuse at least 75% of existing building structures by surface area.
Approach: Create a design that incorporates much of the existing building to achieve this credit.
There are no Exemplary Performance points available for this credit. This is part of the Construction Submittal.
The intent of this credit is to reduce the waste generated by building users.
Requirements: In order to achieve this credit, there needs to be an area for collection and storage of recyclable materials for building occupants to use.
Approach: Incorporate an area early into the design that will meet the requirements of the credit.
There are a few Calculations needed in order to calculate the required area size. There are no exemplary performance points available for this credit. This is part of the Design Submittal.
Building materials have a considerable amount of embodied energy. Embodied energy involves the energy that was expended to create the material. It takes a ton of resources to create the products that we use in construction today. It is important to be recycling materials, reusing existing materials, diverting construction waste, using regional materials to reduce resources expended for shipping, using rapidly renewable materials and certified wood so that our forests are regrown properly.
Intent: Save the environment by utilizing renewable or “Green” power.
The Requirements for this credit involve providing at least 35% of the electricity for the building from renewable sources for 2 years.
Approach: Engage in purchasing a renewable energy contract or renewable energy certificates or credits.
Exemplary Performance is available if you increase the percent from 35% to 70% or if you increase the length from 2 years to 4 years.
This is part of the Construction Submittal.
The Intent of this credit is very important. It is necessary to be able to measure the building’s performance and have accountability for it’s consumption.
Requirements: Create a Measurement and Verification plan that covers at least one year of post-construction occupancy.
Approach: Install necessary features that will allow for the requirements to be achieved.
There are a few Calculations required for the IPMVP Volume III. There are no Exemplary Performance points available for this credit. This is part of the Design Submittal.
The Intent of this credit is to reduce the amount of harmful refrigerants used in cooling systems.
Requirements: You can either not use any refrigerants, or use refrigerants that meet certian specifications pertaining to their LCGWP, LCODP, ODP, GWPr, etc values.
Approach: Select equipment that does not need harmful refrigerants. If doing a building remodel and using existing mechanical equipment, create a comprehensive phase-out plan to eliminate harmful refrigerants.
There are several calculations involved in this credit, and it is part of the design submittal.
Intent: Properly commission the building to ensure proper function of equipment.
Requirements: There are several more requirements for this credit than for the corresponding prerequisite. Take a look at your LEED manual for all the details.
Approach: Follow the directions in the LEED manual.
The Intent of this credit is to increase the use of ons-ite renewable energy.
Requirements: Utilize solar, thermal, wind, etc. renewable energy sources in order to offset the building’s energy costs. 2.5% savings results in 1 point; 7.5% savings results in 2 points, and 12.5% savings results in 3 points.

Approach: Obviously, incorporate renewable energy sources in the design of the building.
There are several Calculations involved with this credit, no Exemplary Performance points available, and it is part of the Design Submittal.
