Sustainable Technology Institute specializes in home performance measures aimed at improving energy efficiency through green principles and sustainability. Of vast importance is viewing your home as a system, meaning that we focus on all of your home’s innerworkings and interdependent systems that influence your home’s energy efficiency. Viewing your home from the whole-house approach will have a greater impact on your energy bills. Instead of focusing on one major system, like your HVAC system, for example, Sustainable Technology Institute will address all of the smaller systems in your home (windows, residents’ patterns of behavior, etc.), along with the larger systems, to give you a full comprehensive view of your home’s energy consumption. With appropriate insulation, air/duct sealing, installation of other measures, and thermostat settings, you can cut your energy use for heating and cooling, and reduce environmental emissions from 20% to 50% (source: U.S. Department of Energy).
