The LEED v4 for Building Design and Construction (LEED BD+C) was finalized in 2013. Rather than product focused, LEED v4 places more emphasis on building system performance in an effort to produce buildings with a lower environmental impact, compared to previous LEED versions, by promoting more sustainable materials and environmentally friendly design, construction and manufacturing methods.
Rather than adopting a stand-alone rating system, as was done in previous versions, the Canada Green Building Council (CaGBC) will be adopting LEED v4. However, because LEED v4 was developed in the United States, which mainly references US standards, the CaGBC will be providing Canadian options to show compliance – termed Alternative Compliance Path (ACP). For example, where an equivalent Canadian standard exists, the ACP can allow the use of that standard, in lieu of the standard required in the LEED requirements.
While some of the building types may seem familiar from previous LEED versions, LEED v4 BD+C now include 8 building types:
1. New Construction
2. Core and Shell
5. Data Centers
6. Warehouses and Distribution Centers
A minimum of 40 points are required to achieve LEED v4 certification. The point system for LEED v4 certification is listed below:
• Certified LEED – 40 to 49
• Silver – 50 to 59
• Gold – 60 to 79
• Platinum – 80 to 110
LEED v4 BD+C include 8 categories. Each category may vary in points based on the building types. The categories total 109 possible LEED points plus and additional point under “Integrative Process.
The categories include:
1. Location and Transportation (16 points)
2. Sustainable Sites (10 points)15
3. Water Efficiency (11 points)12
4. Energy and Atmosphere (33 points)35
5. Material and Resources (13 points)
6. Indoor Environmental Quality (16 points)
7. Innovation (6 points)
8. Regional Priority (4 points)
The categories where ICFs can potentially contribute to gaining LEED points are items 2, 4, 5, and 6, as listed above. The potential LEED point contribution when using ICFs is listed below, with details shown on the next page.
