Energy Use Intensity (EUI) is a way of comparing the energy use of different buildings. Essentially, EUI is energy use per square foot of space. This article talks about EUI, how to calculate it, and some ideas on how to reduce it.
There are a number of green building certification programs and rating systems. Some focus on energy reduction, some focus on occupant health, and others try to cover it all. We review the various rating systems for sustainability, resiliency, and health.
Sustainable products are identified by various certifications. The certifications can be first-part or third-party verified. Certifications follow many standards. Learn how to understand the different product certifications.
Environmental Product Declarations (EPDs) are like nutrition labels on a food product, but geared toward environmental and sustainable attributes. EPDs include the product’s life cycle assessment, from the raw material extraction to its disposal, so we can measure a product’s environmental impact.
Health Product Declarations (HPDs) help owners, architects, and contractors understand what ingredients are in the materials and products that make up our buildings. While they don't declare whether a product is healthy, they provide the transparency for people to evaluate the health safety of our built environment.
A review of the three major red lists used to help architects and users identify safe building materials: the Living Building Challenge Red List, The Perkins & Will Precautionary List, and the Cradle to Cradle material certification.
