By adopting sustainable construction, contractors would make the construction plan or sustainable site plan to minimize the environmental impact of the project. According to a study took place in Sri Lanka, [ 20 ] considerations of sustainability may influence the contractor to choose more sustainable, locally sourced products and materials ...
A deep energy retrofit (DER) is an energy conservation project in an existing building that leads to an overall improvement in building performance.While there is no exact definition for a deep energy retrofit, it can be characterized as a whole-building analysis and construction process that aims to reduce on-site energy use by 50% or more using existing technologies, materials and ...
As of March 2010 more than 550 ESPC projects worth $3.6 billion were awarded to 25 Federal Agencies and organizations in 49 states and the District of Columbia (D.C.). .). These projects saved an estimated 30.2 trillion BTU annually, equivalent to the energy consumed by 318,300, and $11 billion in energy costs, $9.6 billion goes to fund energy efficiency projects and $1.4 billion is reduced ...
The main goal of SEM is to help a company achieve continuous improvement in its energy performance over a longer-term period. Some energy benefits of SEM include reduced energy consumption through improved energy efficiency and energy conservation, improved peak demand management and reduced demand charges, decreased overall energy cost, reduced energy costs, greenhouse gas (GHG) emissions and ...
Note: Energy Consumption for combined commercial and residential sectors is 39% of Total Energy Consumption when electrical system energy losses are included. [1] United States building energy codes are a subset of building codes that set minimum requirements for energy-efficient design and construction for new and renovated buildings. [2]
There are several different building performance standards widely used for designing building codes and energy-efficiency certifications. For instance, the standards produced by ASHRAE (American Society of Heating, Refrigeration, and Air Conditioning Engineers) and the IECC (International Energy Conservation Code) have been widely used to inform local building codes and energy-efficiency ...
The lower the rating, the greater the energy efficiency. For example, a “KfW Efficiency House 70” consumes 70% of this requirement. As such, the best standard (55) receives the greatest support. To meet the energy standard for an efficient home, heating systems, thermal wall insulation, roof and floor insulation and windows are required. [11]
A 2012 study by the American Council for an Energy-Efficient Economy found that multifamily buildings present a tremendous opportunity for energy savings. Comprehensive, cost-effective upgrades in multifamily buildings could improve efficiency by 15-30%, the Council found, representing an annual sector-wide savings of almost US$3.4 billion. [2]
