European Seasonal Energy Efficiency Ratio
In Europe, the seasonal efficiency of refrigeration equipment, chillers and air conditioners is often rated by the European seasonal energy efficiency ratio (ESEER) which is controlled (among others) by the Eurovent Certification Company. A similar standard in the United States is the integrated energy efficiency ratio (IEER). The ESEER is calculated by combining full and part load operating Energy Efficiency Ratios (EER), for different seasonal air or water temperatures, and including for appropriate weighting factors. These values are shown in the following table. The formula for ESEER can then be presented as follows: :ESEER = (EER@100% load × 0.03) + (EER@75% load × 0.33) + (EER@50% load × 0.41) + (EER@25% load × 0.23) Eurovent publishes EER and ESEER values in its ''Directory of Certified Products'' together with cooling capacity and power input for standard conditions at full load for a wide variety of commercially available equipment.

Eurovent
Eurovent is a European organization representing the HVACR, heating, ventilation, air conditioning and refrigeration industry. The majority of the members are small and medium-sized manufacturers. History Eurovent is one of the oldest industry associations of its kind. The association is the result of the merger of the associations CECMA, the European Committee of Constructors of Air Handling Equipment, and CECOMAF, the European Committee of Refrigeration Equipment Manufacturers, in June 1996. The association represents an industry that started to develop in the 1950s, at a time when the market for heating and refrigeration systems started to grow rapidly. Simultaneously, the European Economic Community was founded and marked the start of a unified regulatory system for goods and services. European manufacturers of air handling technologies felt the need for in-depth cross-national coordination and information exchange, leading to the foundation of CECMA (later Eurovent) in 1958 ...

Energy Efficiency Ratio
In the United States, the efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER) which is defined by the Air Conditioning, Heating, and Refrigeration Institute, a trade association, in its 2008 standard AHRI 210/240, ''Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment''. A similar standard is the European seasonal energy efficiency ratio (ESEER). The SEER rating of a unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. The higher the unit's SEER rating the more energy efficient it is. In the U.S., the SEER is the ratio of cooling in British thermal units (BTUs) to the energy consumed in watt-hours. Example For example, consider a 5000 BTU/h (1465-watt cooling capacity) air-conditioning unit, with a SEER of 10 BTU/(W·h), operating for a total of 1000 hours during an annual cooling season (e.g., 8 hours per day for 125 days).

Building Regulations In The United Kingdom
Building regulations in the United Kingdom are statutory instrument (UK), statutory instruments or statutory regulations that seek to ensure that the policies set out in the relevant legislation are carried out. Building regulations approval is required for most building work in the UK. Building regulations that apply across England and Wales are made under powers set out in the Building Act 1984 (c. 55) while those that apply across Scotland are set out in the Building (Scotland) Act 2003. The Building Act 1984, as amended by the (c. 30), permits detailed regulations to be made by the Secretary of State for England and by a Welsh Minister for Wales. As 'Building Regulations' and 'Building Safety' are devolved areas of law, in the four parts of the UK. The building regulations made under the Building Act 1984 have been periodically updated, rewritten or consolidated, with the latest and current version being the Building Regulations 2010. The UK Government (at Westminster) is r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISBEM
iSBEM is a free of cost proprietary software interface to the Simplified Building Energy Model (SBEM) which is designed for the purpose of indicating compliance with UK building regulations part L2a and L2b in England and section 6 in Scotland as regards carbon emission Greenhouse gas (GHG) emissions from human activities intensify the greenhouse effect. This contributes to climate change. Carbon dioxide (), from burning fossil fuels such as coal, oil, and natural gas, is the main cause of climate change. The l ...s from non domestic buildings. The latest version at time of writing is V 5.6.a which is available as a download from the EPBD NCM website. It has recently underwent additional programming to allow it to be used for producing EPCs for Non-Domestic Buildings. Several commercial software tools exist, offering a more 'user-friendly' front-end to the SBEM calculation engine than iSBEM. The SBEM calculation engine has some limitations and is explicitly distributed a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Directive On The Energy Performance Of Buildings
The Energy Performance of Buildings Directive (2024/1275), the "EPBD") is the European Union's main legislative instrument aiming to promote the improvement of the energy performance of buildings within the European Union. It was inspired by the Kyoto Protocol which commits the EU and all its parties by setting binding emission reduction targets. History Directive 2002/91/EC The first version of the EPBD, directive 2002/91/EC, was approved on 16 December 2002 and entered into force on 4 January 2003.European Commission,DIRECTIVE 2002/91/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 16 December 2002 on the energy performance of buildings, Official Journal of the European Communities, 2003 EU Member States (MS) had to comply with the Directive within three years of the inception date (4 January 2006), by bringing into force necessary laws, regulations and administrative provisions. In the case of lack of qualified and/or accredited experts, the directive allowed for a furth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
