3 0/6/ MRp Storage and ollection of Recyclables Prerequisite (points NA), design submival Facilitate the reduchon of waste generated by building occupants that is hauled to and disposed of in landfills and SubmiVal Provide an easily accessible area that serves the enhre building and is dedicated to the collechon and storage of materials for recycling, including (at a minimum paper, corrugated card board, glass, plashcs and metals) MRc. Building Reuse Maintain Existing Walls - 3 points (0 EP points), construchon submival Extend the life cycle of exishng building stock, conserve resources, retain cultural resources, reduce waste and reduce environmental impacts of new buildings as they relate to materials manufacturing and transport Maintain at least the following percentages of exishng building structure and envelope. 55% ( point) 75% ( points) 95% (3 points) 3

4 0/6/ MRc. Building Reuse Maintain Existing Walls alculahons and Submissions alculahons based on surface area Structure includes structural floor and roof decking Envelope include exterior skin and framing, but excludes window assemblies and non- structural roofing material Remediated hazardous materials not included If project is a building addihon, sq a cannot be more than x exishng building MRc. Building Reuse Maintain Interior Non-Structural Elements point(0 EP points), construchon submival same as WRc. Use exishng interior non- structural elements in at least 50% (by area) of the completed building (including addihons). alculahons/submissions Non- structural elements include interior walls, doors, floor coverings and ceiling systems NA if sq a of addihon is more than x exishng 4

5 0/6/ MRc onstruction Waste Management - points ( EP point), construchon submival Divert construchon and demolihon (&D) debris from disposal in landfills and incinerators. Redirect recyclable recovered resources back to the manufacturing process. Redirect reusable materials to appropriate sites. Recycle/salvage the following percentages of non- hazardous &D debris. Develop and implement a construchon waste management plan that, at a minimum, idenhfies the amterials to be diverted from disposal and whether the materials will be sorted on- site or commingled. 50% ( point) 75% ( points) EP = point for 95% MRc onstruction Waste Management alculahons and SubmiVals Excavated soil and land- clearing debris do not contribute alculahons done by weight or volume, but must be consistent throughout WMP should have contract and oversight in place to track materials and pickup when full 5

6 0/6/ MRc3 Materials Reuse - points ( EP point), construchon submival Reuse building materials and products in order to reduce demand for virgin materials and to reduce waste, thereby reducing impacts associated with the extrachon and processing of virgin resources. Use salvaged, refurbished or reused materials in the percentages listed (based on cost) of the total value of materials on the project. 5% ( point) 0% ( points) EP= for 5% Big dig house MRc3 Materials Reuse alculahons and SubmiVals Mechanical, electrical, plumbing, elevators, special equipment, etc, do not count Include only permanently installed materials Furniture may be included if it is consistently included with MRc3-7. Salvaged furniture from the occupant s previous facility should be at least years old at start of new project Materials included for diversion or building reuse cannot be counted Materials counted for MRc3 cannot be used for MRc,, 4, 6, or 7, but if MRc3 is not avempted, applicable materials can be applied to other credits ost values of salvaged items for calculahons represent either the cost of salvaging (refurbishing, purchase) or the market value of the equivalent new item (whichever is greater) Materials can be salvaged from on- site (previous building) or off- site 6

7 0/6/ MRc4 Recycled ontent - points (0 EP points), construchon submival Increase demand for building products that incorporate recycled content materials, thereby reducing impacts resulhng from extrachon and processing of virgin materials. Use materials with recycled content such that the sum of post- consumer recycled content plus ½ of the pre- consumer content conshtutes at least the following % of the total cost of the materials in the project. 0% ( point) 0% ( points) alculahons and SubmiVals No mechanical, etc Only permanently installed materials onsistent use of furniture in MR calculahons Recycled content value of an assembly by weight (some alternahves, such as in cement replacement for concrete accepted) MRc5 Regional Materials - points ( EP point), construchon submival Increase the demand for building materials and products that are extracted and manufactured within the region, thereby supporhng the use of indigenous resources and reducing the environmental impacts resulhng from transportahon. Use building materials or products that have been extracted, harvested or recovered, as well as manufactured, within 500 miles of the project site for the percentages of total cost as given below. 0% ( point) 0% ( points) EP = for 40% alculahons and SubmiVals For frachons of local material used, then only count the % by weight Same restrichons on mechanical, permanently installed, furniture, etc. Materials under MRc5 can be used for MRc3, 4, 6, and 7 7

8 0/6/ MRc6 Rapidly Renewable Materials point ( EP point), construchon submival Reduce the use and deplehon of finite raw materials and long- cycle renewable materials by replacing them with rapidly renewable materials Use rapidly renewable building materials and products (made from plants typically harvested within a ten- year cycle or less) for the percentages of total cost as given below..5% ( point) EP = for 5% alculahons and SubmiVals Animal based products can be used (wool) Some examples: bio- based paints, jute geotexhles, soy- based insulahon, straw bales, linoleum (linseed oil, cork dust, pine rosin, wood flour), bamboo, cork MRc7 ertified Wood point ( EP point), construchon submival Encourage environmentally responsible forest management Use a minimum % of total wood- based products that are FS (Forest Stewardship ouncil) cerhfied 50% ( point) EP = for 95% alculahons and SubmiVals Furniture if consistent Temporary products (shoring, forming, etc) can be included if all are included (and can only be included for one project if used mulhple Hmes) New wood only (salvaged elsewhere) 8
