Deep Energy Retrofit
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 construction practices.Less, Brennan, et al. "Deep Energy Retrofit x 10." Home Energy, vol. 29, no. 3, 2012, p. 38."The Retrofit Depot", Rocky Mountain Institute, 2018, https://www.rmi.org/our-work/buildings/deep-retrofit-tools-resources/deep-retrofit-case-studies/. Accessed Dec 2018. Reductions are calculated against baseline energy use using data from utility bills. Such a retrofit reaps multifold (energy and non-energy) 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Conservation
Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less and better sources of energy for continuous service) or changing one's behavior to use less and better source of service (for example, by driving vehicles which consume renewable energy or energy with more efficiency). Energy conservation can be achieved through efficient energy use, which has some advantages, including a reduction in greenhouse gas emissions and a smaller carbon footprint, as well as cost, water, and energy savings. Green engineering practices improve the life cycle of the components of machines which convert energy from one form into another. Energy can be conserved by reducing waste and losses, improving efficiency through technological upgrades, improving operations and maintenance, changing users' behaviors through user profiling or user activities, monitoring appliances, shifting load to o ...

Energy Audit
Energy () is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, the internal energy contained within a thermodynamic system, and rest energy associated with an object's rest mass. These are not mutually exclusive. All living organisms constantly take in and release energy. The Earth's climate and ecosystems processes are drive ...

Johnson Controls
Johnson Controls International plc is an American, Irish-domiciled multinational conglomerate headquartered in Cork, Ireland, that produces fire, HVAC, and security equipment for buildings. As of mid-2019, it employed 105,000 people in around 2,000 locations across six continents. In 2017 it was listed as 389th in the ''Fortune'' Global 500. It became ineligible for the ''Fortune'' 500 in subsequent years since it relocated its headquarters outside the U.S. The company was formed via the merger of American company Johnson Controls with Tyco International, announced on 25 January 2016. The merger led to the avoidance of taxation on foreign market operations and a financial windfall for the CEO of Johnson Controls at that time, Alex Molinaroli.Stephen Gandell.You Won't Believe How Much Johnson Controls' CEO Is Making on the Tyco Deal.

Greenhouse Gas
Greenhouse gases (GHGs) are the gases in the atmosphere that raise the surface temperature of planets such as the Earth. Unlike other gases, greenhouse gases absorb the radiations that a planet emits, resulting in the greenhouse effect. The Earth is warmed by sunlight, causing its surface to radiate heat, which is then mostly absorbed by greenhouse gases. Without greenhouse gases in the atmosphere, the average temperature of Earth's surface would be about , rather than the present average of .Le Treut, H., R. Somerville, U. Cubasch, Y. Ding, C.

Carbon Footprint
A carbon footprint (or greenhouse gas footprint) is a calculated value or index that makes it possible to compare the total amount of greenhouse gases that an activity, product, company or country Greenhouse gas emissions, adds to the atmosphere. Carbon footprints are usually reported in tonnes of emissions (CO2 equivalent, CO2-equivalent) per unit of comparison. Such units can be for example ''tonnes CO2-eq per year'', ''per kilogram of protein for consumption'', ''per kilometer travelled'', ''per piece of clothing'' and so forth. A product's carbon footprint includes the emissions for the entire Life-cycle assessment, life cycle. These run from the production along the supply chain to its final consumption and disposal. Similarly, an organization's carbon footprint includes the direct as well as the indirect emissions that it causes. The Greenhouse gas protocol, Greenhouse Gas Protocol (for carbon accounting of organizations) calls these ''Scope 1, 2 and 3 emissions''. There a ...

Effects Of Climate Change
Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an Instrumental temperature record, overall warming trend, Effects of climate change on the water cycle, changes to precipitation patterns, and more extreme weather. As the climate changes it impacts the natural environment with effects such as more intense forest fires, thawing permafrost, and desertification. These changes impact ecosystems and societies, and can become irreversible once Tipping points in the climate system, tipping points are crossed. Climate activists are engaged in a range of activities around the world that seek to ameliorate these issues or prevent them from happening. The effects of climate change vary in timing and location. Up until now the polar amplification, Arctic has warmed faster than most other regions due to climate change feedbacks. Surface air temperatures over land have also increased at ab ...

Climate Change Mitigation
Climate change mitigation (or decarbonisation) is action to limit the greenhouse gases in the atmosphere that cause climate change. Climate change mitigation actions include energy conservation, conserving energy and Fossil fuel phase-out, replacing fossil fuels with sustainable energy, clean energy sources. Secondary mitigation strategies include changes to land use and carbon sequestration, removing carbon dioxide (CO2) from the atmosphere. Current climate change mitigation policies are insufficient as they would still result in global warming of about 2.7 °C by 2100, significantly above the 2015 Paris Agreement's goal of limiting global warming to below 2 °C. Solar energy and wind power can replace fossil fuels at the lowest cost compared to other renewable energy options.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

Carbon Disclosure Project
The CDP (formerly the Carbon Disclosure Project) is an international non-profit organisation based in the United Kingdom, Japan, India, China, Germany, Brazil and the United States that helps companies, cities, states, regions and public authorities disclose their environmental impact. It aims to make environmental reporting and risk management a business norm, driving disclosure, insight, and action towards a sustainable economy. In 2022, nearly 18,700 organizations disclosed their environmental information through CDP. Background CDP piggybacked on GRI's concept of environmental disclosure in 2002, focusing on individual companies rather than on nations. At the time CDP had just 35 investors signing its request for climate information and 245 companies responding. According to the organization, as of 2022, companies worth half of global market capitalization disclose through CDP. Mechanism CDP works with corporations, cities, states, and regions to help develop carbon e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Reporting Initiative
The Global Reporting Initiative (known as GRI) is an international independent standards organization that helps businesses, governments, and other organizations understand and communicate their impacts on issues such as climate change, human rights, and corruption. Since its first draft guidelines were published in March 1999, GRI's voluntary sustainability reporting framework has been adopted by multinational organizations, governments, small and medium-sized enterprises (SMEs), NGOs, and industry groups. Over 10,000 companies from more than 100 countries use GRI. According to the 26 October 2022 KPMG Survey of Sustainability Reporting, 78% of the world’s biggest 250 companies by revenue (the G250) and 68% of the top 100 businesses in 58 countries (5,800 companies known as the N100) have adopted the GRI Standards for reporting. GRI is used as a reporting standard by a majority of the companies surveyed in all regions. GRI thus provides the world's most widely used sustaina ...
