Since then, IEA EBC's main aim has been to provide an international focus for energy efficiency research in the building sector, with its current mission being to “develop and facilitate the integration of technologies and processes for energy efficiency and conservation into healthy, low emission and sustainable buildings and communities ...
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]
Building Stock Analysis: support development of energy codes and standards and plan large scale energy efficiency programs CFD in buildings: simulation of boundary conditions like surface heat fluxes and surface temperatures for a following CFD study of the situation [ 40 ]
Sustainable refurbishment describes working on existing buildings to improve their environmental performance using sustainable methods and materials. A refurbishment or retrofit is defined as: "any work to a building over and above maintenance to change its capacity, function or performance' in other words, any intervention to adjust, reuse, or upgrade a building to suit new conditions or ...
ANSI/ASHRAE/IES Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings is an American National Standards Institute (ANSI) standard published by ASHRAE and jointly sponsored by the Illuminating Engineering Society (IES) that provides minimum requirements for energy efficient designs for buildings except for low-rise residential buildings (i.e. single-family homes ...
Sustainable rating systems are used to evaluate the environmental performance of buildings. These systems have common criteria and are similar in their evaluation of energy consumption, indoor environmental quality, water efficiency, and material. Three rating systems that can integrate with BIM are LEED, BREEAM, and Green Star. [6] The ...
Those building high-performance buildings, or renovating an existing building for improved energy and climate performance, often seek to reduce greenhouse gas emissions by using a low carbon energy system such an electric heat pump instead of a natural gas furnace or hot water heater. In the United States, a growing movement is seeking to ...
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 ...
