The biggest hurdle for energy efficiency in the built environment today is how to improve the energy efficiency of our existing housing stock in an affordable manner. These three practitioners bring several years of experience to the fore. They have seen what works, what doesn't, and why. The session will review the best building practices of how to view, evaluate and perform an energy upgrade to a property. Average square foot costs on energy efficiency return will be discussed and what can be the expected energy reductions from certain projects. This session will focus on some of the easier energy-efficiency upgrades to be taken now and what to put off to employ our next generation. Evaluation of the existing available financial resources to be used for offsetting the owner costs and how they might be improved. Lastly, they will address when a project is beyond the scope of affordability and what telltale signs to look for.
