Not only did developer Del Ridge Homes build Appleby Woods to be energy efficient, they saved money while doing so. The 101-suite condo uses only 10 equivalent kilowatt hours per square foot per year, which is 50% less energy and greenhouse gas emissions than a typical new building built to code. Units in Appleby Woods cost 25% less per square foot than comparable buildings and have 60% lower condo fees. Del Ridge’s savings came from using pre-fabricated materials as well as an R45 insulated concrete form (ICF) system. They also reduced energy demand by using motion sensors, high-efficiency lighting, and geo-exchange heating and cooling systems. This case study proves that by taking an integrated design approach in new buildings it is possible to deliver exceptional energy performance at no additional cost.
