"CPD 4: Energy Efficient Building Envelopes"co.MassSave – MassSave provides both incentives to commercial/industrial/institutional customers as well as interest-free loans of up to $500,000 for energy efficiency projects.Utility energy efficiency programs – Utilities such as National Grid and Eversource provide incentives and rebates for a wide range of energy efficiency technologies and upgrades for retrofits and new construction.Split incentive between tenant and property owner creates a significant barrier to major energy efficiency investmentįinancing Options, Incentives, and Rebates.It also defines technology attributes, integration considerations, and barriers to achieving the full potential, adoption and deployment of GEB. Highly insulated buildings carry higher risk of moisture-related damage The Roadmap outlines DOE’s national goal to triple the energy efficiency and demand flexibility of the buildings sector by 2030, relative to 2020 levels.Significant upfront costs result in long payback for energy efficient technologies.In the event of blackouts, buildings can remain hospitable for greater periods of time.Significant reductions to building energy use for both heating and cooling.Building owners interested in making energy efficiency improvements to their buildings should conduct energy audits to determine the most cost-effective methods to improve the efficiency of the building envelope. Insulation and air sealing through effective air barrier systems can reduce non-residential building electricity consumption by more than 25%. The amount of energy saved depends on the building and the technologies used, though ENERGY STAR buildings have been shown to reduce operating costs for corporate real estate owners by up to $25,000 per year for every 10,000 square feet of office space. The technologies deployed can address a number of sources of energy loss such as air leakage, wet insulation, and thermal bridging. Heating, cooling, and ventilation are responsible for around a third of primary energy use in the commercial and residential sectors, and energy represents approximately 30% of the typical office building’s costs. The use of a range of building technologies to create an energy efficient building envelope reduces both the thermal energy lost to the building’s surroundings and the amount of energy needed to heat and cool the building. thermal, light, and acoustic comfort, humidity conditions). protection from the elements) and preservation of internal space requirements (e.g. The building envelope, the boundary between the interior and exterior of a building, performs a number of tasks including exterior protection (e.g.
