Case Studies
Retrofitting Large Buildings
Every building is unique and the process of renovating each building presents its own challenges. Here are some case studies of successful projects to improve energy efficiency or water efficiency performance, reduce greenhouse gas emissions, or improve indoor air quality.
If you have a case study you’d like to showcase here, please contact the Hub.
