Redevelopment of Contaminated Sites: 1 point
Sustainable Sites, Credit 3
- Cement can be used to solidify and stabilize contaminated soil to reduce leaching
- To qualify, proof of contamination must exist
Reduced Site Disturbance (Protect/Restore Open Space): 1 point
Sustainable Sites, Credit 5.1
- Build parking space under the building in lieu of using external space
- Reduce need for clearing vegetation to accommodate parking
- Limit site disturbance to 12m beyond building perimeter
Reduced Site Disturbance (Development Footprint): 1 point
Sustainable Sites, Credit 5.2
- Build parking space under the building in lieu of using external space
- Reduce need for external paving to accommodate parking
- Exceed local zoning open space requirements by 25%
Stormwater Management (Rate & Quantity): 1 point
Sustainable Sites, Credit 6.1
- Limit disruption and pollution of natural water flow
- Can be achieved using highly-permeable pervious concrete
- On sites with >50% imperviousness, reduce quantity of stormwater runoff by 25%
- On sites with <50% imperviousness, building must maintain or lessen stormwater runoff
Heat Island Effect (Non-Roof): 1 point
Sustainable Sites, Credit 7.1
- Use light-coloured or reflective exterior building materials for 30% of structure (not including roof)
- Concrete made with Portland cement, rather than asphalt can help to meet the requirement
- Another option is to place 50% of parking spaces underground
Minimum Energy Performance: Required (no points associated)
Energy & Atmosphere Prerequisite, Credit 2
- Demonstrate energy savings using a whole building energy simulation system
Optimize Energy Performance: Number of points varies
Energy, Credit 1
- Credit is allowed if energy cost savings can be shown compared to a base building
- Base must meet MNECB or ANSI/ASHRAE/IESNNA 90.1-1999 requirements
- Insulated concrete will most likely be eligible for points
Building Reuse: Number of points varies from 1 to 3
Materials, Credit 1
- Credit requires main portion of building to remain in place while renovating
- 75% of building left in place: 1 point
- 95% of building left in place: 2 points
- 50% of non-shell areas maintained: 3 points
Construction Waste Management: Number of points varies from 1 to 2
Materials, Credit 2
- Diverting construction/demolition/land waste from landfills
- Must divert 50% weight by volume
- Concrete is relatively heavy and can be crushed and recycled
- 50% of waste recycled or salvaged: 1 point
- 75% of waste recycled or salvaged: 2 points
- Important note: for concrete, just one of the “building reuse” or “construction waste management” credits can be applied for
Recycled Content: Number of points varies from 1 to 2
Materials, Credit 4
- This credit can be applied for if a certain composition of the building is made using post-consumer goods
- Sum of post-consumer recycled content plus ½ the post-industrial recycled content constitutes >7.5% of the materials’ value: 1 point
- Sum of post-consumer recycled content plus ½ the post-industrial recycled content constitutes >15% of the materials’ value: 2 points
- Using recycled concrete or slag as aggregate instead of extracted aggregates would qualify as post-consumer
Regional Content: Number of points varies from 1 to 2
Materials, Credit 5
- Supports the use of indigenous materials and reduced product transportation
- Credit recognizes the reduced impacts of rail or ship compared to truck
- Sourcing concrete mixes from local suppliers can help achieve this credit as many suppliers also source mix components locally as well
- Meeting all requirements: 1 point
- Surpassing requirements by 100%: 2 points
Durable Building: 1 point
Materials, Credit 8
- Incentive for durable buildings, recognizing resources required to replace materials with a short service life
- Concrete boasts an extreme longevity and can help in achieving this credit
