Qualitative Impacts
Physical Properties
- Responsible sourcing
- Thermal properties
- Social impacts
- Acoustic properties
Economic Impacts
- Life cycle costing
Emissions In-situ
- IAQ and VOCs
Benefits of an Environmental Profile
• Green Guide Rating can be used to
compare:
– Materials with similar functions
– Specifications with similar functions
– Building designs over their expected
lifetimes
• Credits in BREEAM
• Product differentiation
• Competitive advantage
• Open new markets
Cross-listing against Existing Certificates
Criteria for cross-listing:
– The product to be cross-listed against must
have an existing Environmental Profile
Certification.
– The product to be cross-listed must have no
additional manufacturing by the owner or by the
company buying in the product. (It is the same
product that has been certified e.g. re-branded
with a different name)
– Cross listing is dependent upon valid
certification of original product.
