Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service. This can be achieved either by using energy more efficiently or by reducing the amount of service used. Energy conservation is a part of the concept of Eco-sufficiency. Energy conservation measures (ECMs) in buildings reduce the need for energy services and can result in increased environmental quality, national security, personal financial security and higher savings. It is at the top of the sustainable energy hierarchy. It also lowers energy costs by preventing future resource depletion.
Natural ResourcesCanada, also known as the Department of Natural Resources, is the department of the federal Government of Canada responsible for natural resources, energy, minerals and metals, forests, earth sciences, mapping, and remote sensing. It was created in 1995 by amalgamating the now-defunct Department of Energy, Mines and Resources with the Department of Forestry.
An eco-industrial park (EIP) is an industrial park in which businesses cooperate with each other and with the local community in an attempt to reduce waste and pollution, efficiently share resources, and help achieve sustainable development, with the intention of increasing economic gains and improving environmental quality. An EIP may also be planned, designed, and built in such a way that it makes it easier for businesses to co-operate, and that results in a more financially sound, environmentally friendly project for the developer.
Ecolabels and Green Stickers are labeling systems for food and consumer products. The use of ecolabels is voluntary, whereas green stickers are mandated by law; for example, in North America major appliances and automobiles use Energy Star. They are a form of sustainability measurement directed at consumers, intended to make it easy to take environmental concerns into account when shopping. Some labels quantify pollution or energy consumption by way of index scores or units of measurement, while others assert compliance with a set of practices or minimum requirements for sustainability or reduction of harm to the environment. Many ecolabels are focused on minimising the negative ecological impacts of primary production or resource extraction in a given sector or commodity through a set of good practices that are captured in a sustainability standard. Through a verification process, usually referred to as "certification", a farm, forest, fishery, or mine can show that it complies with a standard and earn the right to sell its products as certified through the supply chain, often resulting in a consumer-facing ecolabel.
A Zero Energy Building (ZEB), also known as a Net Zero Energy (NZE) building, or a Zero Net Energy (ZNE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows and insulation, and solar panels. The goal is that these buildings contribute less overall greenhouse gas to the atmosphere during operations than similar non-ZNE buildings. They do at times consume non-renewable energy and produce greenhouse gases, but at other times reduce energy consumption and greenhouse gas production elsewhere by the same amount. Zero-energy buildings are not only driven by a want to have less of an impact on the environment, but they are also driven by money. Tax breaks as well as savings on energy costs make Zero-energy buildings financially viable. A similar concept approved and implemented by the European Union and other agreeing countries is nearly Zero Energy Building (nZEB), with the goal of having all new buildings in the region under nZEB standards by 2020.
The U.S. Green Building Council (USGBC), co-founded by Mike Italiano, David Gottfried and Rick Fedrizzi in 1993, is a private 501(c)3, membership-based non-profit organization that promotes sustainability in building design, construction, and operation. USGBC is best known for its development of the Leadership in Energy and Environmental Design (LEED) green building rating systems and its annual Greenbuild International Conference and Expo, the world’s largest conference and expo dedicated to green building. USGBC was one of eight national councils that helped found the World Green Building Council (WorldGBC). The current president and CEO is Peter Templeton.
Retrofitting is the addition of new technology or features to older systems. Retrofits can happen for a number of reasons, for example with big capital expenditures like naval vessels, military equipment or manufacturing plants, businesses or governments may retrofit in order to reduce the need to replace a system entirely. Other retrofits may be due to changing codes or requirements, such as seismic retrofit which are designed strengthening older buildings in order to make them earthquake-resistant.
EnerGuide is the official Government of Canada mark associated with the labelling and rating of the energy consumption or energy efficiency of specific products. The EnerGuide's efficiency percent is calculated by dividing the power output by power input. EnerGuide labelling exists for appliances, heating and cooling equipment, houses and vehicles.
Sustainable Development Strategy for organizations in Canada is about the Government of Canada finding ways to develop social, financial, and environmental resources that meet the needs of the present without compromising the ability of future generations to meet their own needs in Canada. A Sustainable Development Strategy for the organization needs to be developed that establishes the Sustainable Development goals and objectives set by the Auditor General Act of Canada and provides the written policies and procedures to achieve them. Sustainable Development is based on responsible decision-making, which considers not only the economic benefits of development, but also the short-term and long-term, Canadian environment and environmental impacts.
An energy audit is an inspection survey and an analysis of energy flows for energy conservation in a building. It may include a process or system to reduce the amount of energy input into the system without negatively affecting the output. In commercial and industrial real estate, an energy audit is the first step in identifying opportunities to reduce energy expense and carbon footprint.
Efficient energy use, sometimes simply called energy efficiency, is the goal to reduce the amount of energy required to provide products and services and can also reduce effects of air pollution. For example, insulating a building allows it to use less heating and cooling energy to achieve and maintain a thermal comfort. Installing light-emitting diode bulbs, fluorescent lighting, or natural skylight windows reduces the amount of energy required to attain the same level of illumination compared to using traditional incandescent light bulbs. Improvements in energy efficiency are generally achieved by adopting a more efficient technology or production process or by application of commonly accepted methods to reduce energy losses.
R-2000 is a Natural Resources Canada (NRCan) program that was developed in partnership with the Canadian Home Builders' Association in 1981, and formalized as a standard in 1982. Notably, the R-2000 standard is a voluntary standard to exceed building code requirements for energy efficiency, indoor air quality, and environmental responsibility.
The United States Department of Energy's State Energy Program (SEP) provides grants to states and directs funding to state energy offices from technology programs in Office of Energy Efficiency and Renewable Energy. States use grants to address their energy priorities and program funding to adopt emerging renewable energy and energy efficiency technologies. Started in 2010, the program "is the only program administered by the U.S. Department of Energy (DOE) that provides cost-shared resources directly to the states for allocation by the governor-designated State Energy Office for use in energy efficiency and clean energy innovation, development, and demonstration activities.”
An Energy Rebate Program, or Energy Credit Incentive Program, provides a cash rebate program for customers planning to install new, energy efficient information technology (IT) equipment or cooling systems. These programs push companies to construct more energy efficient data centers, or to consolidate compute, storage and networking resources via virtualization technologies.
Toronto Solar Neighbourhoods Initiative is a joint project of the Atmospheric Fund and Toronto Energy Efficiency Office, with support from the Toronto Environment Office and Toronto Hydro. Its goal is to encourage the installation of solar water heating systems in Toronto homes through financial incentives and other support to both homeowners and the local solar industry. Phase I (2008-2009) of the pilot project is targeting homes in Toronto’s Ward 30. The program was developed based on a directive in Toronto’s “Climate Change, Clean Air and Sustainable Energy Action Plan”, which was approved by Toronto City Council in June 2007.
Canada has implemented the "R-2000" in 1982 to promote better than building code construction to increase energy efficiency and promote sustainability. An optional feature of the R-2000 home program is the EnerGuide rating service. This service is available across Canada, allows home builders and home buyers to measure and rate the performance of their homes, and confirm that those specifications have been met. Some Canadian provinces are considering mandatory use of the service for all new homes.
A green retrofit is any refurbishment of an existing building that aims to reduce the carbon emissions and environmental impact of the building. This includes, but is not limited to, improving the energy efficiency of the heating, air conditioning, ventilation, and other mechanical systems, increasing the quality of insulation in the building envelope, implementing sustainable energy generation, and aiming to improve occupant comfort and health.
A Deep energy retrofit can be broadly categorized as an energy conservation measure in an existing building also leading to an overall improvement in the building performance. While there is no exact definition for a deep energy retrofit, it can be defined as a whole-building analysis and construction process that aims at achieving on-site energy use minimization in a building by 50% or more compared to the baseline energy use making use of existing technologies, materials and construction practices. Such a retrofit reaps multifold benefits beyond energy cost savings, unlike conventional energy retrofit. It may also involve remodeling the building to achieve a harmony in energy, indoor air quality, durability, and thermal comfort. An integrated project delivery method is recommended for a deep energy retrofit project. An over-time approach in a deep energy retrofitting project provides a solution to the large upfront costs problem in all-at-once execution of the project.
DERs are projects that create new, valuable assets from existing residences, by bringing homes into alignment with the expectations of the 21st century
The North Carolina Solar Center is a resource center for sustainable energy programs located at North Carolina State University in Raleigh, North Carolina. When it was created in 1988, the center's focus was solar energy. The N.C. Solar Center now serves as a resource for innovative, clean energy technologies through demonstration, technical assistance, outreach and training. It also administers the Database of Incentives for Renewables & Efficiency (DSIRE), a resource providing financial incentives and policies in the energy industry.
The BC Energy Step Code is a provincial regulation that local governments in British Columbia, Canada, may use, if they wish, to incentivize or require a level of energy efficiency in new construction that goes above and beyond the requirements of the base building code. It is an example of a "stretch code," or "reach code," in that it is an appendix to a mandatory minimum energy code that allows communities to voluntarily adopt a uniform approach to achieving more ambitious levels of energy efficiency in new construction.
