MR Credit 1.1: Building Reuse: Maintain 75% of Existing Walls,
Floors & Roof
1 Point
Intent
Extend the life cycle of existing building stock, conserve
resources, retain cultural resources, reduce waste and
reduce environmental impacts of new buildings as they relate to
materials manufacturing and transport.
Requirements
Maintain at least 75% (based on surface area) of existing building
structure (including structural floor and roof
decking) and envelope (exterior skin and framing, excluding window
assemblies and non-structural roofing material).
Hazardous materials that are remediated as a part of the project
scope shall be excluded from the calculation
of the percentage maintained. If the project includes an addition to
an existing building, this credit is not applicable
if the square footage of the addition is more than 2 times the
square footage of the existing building.
Potential Technologies & Strategies
Consider reuse of existing, previously occupied buildings, including
structure, envelope and elements. Remove
elements that pose contamination risk to building occupants and
upgrade components that would improve
energy and water efficiency such as windows, mechanical systems and
plumbing fixtures. |
