![]() ![]() A well-designed building envelope will lose (or, in the summer, gain) heat much more slowly, resulting in less need to run the HVAC system. While there are specific considerations for each project, typically the first step is ensuring that the building envelope is well insulated and sealed. ![]() Whole-Building SavingsĪCEEE advocates using a whole-building approach to saving energy in new and existing buildings. A whole-building approach considers the building envelope, HVAC system, water-heating system, appliances, and other equipment in the building and uses energy modeling to identify the most cost-effective opportunities for improving efficiency. Federal, state, local, and utility incentives can reduce the upfront cost of many of these upgrades. ACEEE seeks to advance evidence-based clean energy solutions that not only significantly reduce carbon emissions but also advance social equity, maximize the health and well-being of all people, and help ensure a just and inclusive clean energy transition. Given the scale of energy and carbon resources dedicated to these buildings and homes, there is a significant opportunity to achieve savings. Buildings and homes consume approximately 75% of the electricity used in the United States, and they account for 40% of primary energy use and corresponding greenhouse gas emissions. ![]()
