Dave Ramslie and Gerry Faubert, Principals, Integral Group Reenergizing our Cities! – Integrated District Scale Energy Planning Investment in our buildings and infrastructure has never been more timely. Energy solutions that work for both new development and for the retention and re-imagining of our existing buildings are possible today. The scale and application of these solutions from grass roots community engagement programs, to retro-commissioning, big data and the development of large sale renewable energy solutions can work together to lower emissions and improve our collective quality of life. Using case studies such as the development of new district ambient loop in downtown Vancouver using existing fire protection infrastructure and the promotion of deep green retrofits in multi-unit residential buildings through the Condo Retrofit Assistance Financing Trial (CRAFT) Dave Ramslie and Gerry Faubert will examine how a variety of solutions deployed at the neighborhood level can be aligned to achieve significant community wide energy savings and economic revitalization.
