MRc7: Certified Wood

The intent of this credit is to encourage the use of wood that is harvested in a renewable manner.  The US Green Building Council wants to reward those projects which use wood that promotes environmentally responsible forest management.
You can achieve this credit if 50% of your wood based products are FSC certified (Forest Stewardship Council).  […]

MRc6: Rapidly Renewable Materials

This credit helps encourage people to use rapidly renewable materials in their project.  These rapidly renewable materials include things such as bamboo, wool, cotton insulation, agrifiber, linoleum, wheatboard, strawboard and cork.  The reason that using rapidly renewable materials is considered “Green” is because they are very abundant and easy to renew.  Wood is considered a […]

MR 5.1 & 5.2: Regional Materials

The intent of this credit is to have construction sites use materials that are considered “local”.  The thing which defines “local” is being harvested and manufactured within 500 miles of the jobsite.  The reason this is a sustainable practice is because it helps cut down on the emissions and fuel consumption used in transporting materials […]

MR 4.1 & 4.2: Recycled Content

There are a total of three points available for this topic.  You have the 4.1 which is your basic 10%, you have the 4.2 which is your more advanced 20%, but then if you hit a whopping 30%, you can apply for an additional ID credit for exemplary performance.
This whole intent of this credit is […]

MR3.1: Materials Reuse

Intent: Implement the use of used materials into the design to reduce the demand for new materials.
In order to achieve this credit, you are required to use salvaged, refurbished or reused materials for 5% of the total cost of all materials for the job.
Approach: Incorporate the use of used materials into the design.
The calculations  involve […]

MRc2.2: Construction Waste Management

This is the same credit as MRc2.1, however the level of recycling is increased to 75% from 50%.  Keep in mind that if you hit 95% recycling on the jobsite, you will be eligible for 3 points: MRc2.1, MRc2.2 and the exemplary performance ID credit.

MRc2.1: Construction Waste Management

The intent of this credit is to recycle more construction material and divert construction waste from the landfill.
Requirements: Divert at least 50% of the construction waste from the landfill.  This 50% is to be either weight or volume, but the calculations must be consistant throughout.
Approach: Recycle as much of the construction waste as possible.  Designate […]

MRc1.3: Building Reuse (Interior Non-Structural Elements)

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.

MRc1.2: Building Reuse

Same as MRc1.1, except increase the amount required from 75% to 95%.

MRc1.1: Building Reuse

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 […]
