ESEER
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.

Seasonal 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. The coefficient of performance ( COP), a more universal unit-less measure of efficiency, is discussed in the following section. Example For example, consider a 5000 BTU/h (1465-watt cooling capacity) air-conditioning unit, with a SEER of 10&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eurovent
Eurovent is Europe's Industry Association for Indoor Climate (HVAC), Process Cooling, and Food Cold Chain Technologies. Its members from throughout Europe represent more than 1.000 companies, the majority small and medium-sized manufacturers. The organisation's activities are based on highly valued democratic decision-making principles, ensuring a level playing field for the entire industry independent from organisation sizes or membership fees. History Eurovent is one of the oldest industry associations of its kind. The association as we know it today 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. 1951-1960: European Union and association development 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. ...

Building Regulations In The United Kingdom
Building regulations in the United Kingdom are 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 set out in the Building Act 1984 while those that apply across Scotland are set out in the Building (Scotland) Act 2003. The Act in England and Wales permits detailed regulations to be made by the Secretary of State. The regulations made under the Act have been periodically updated, rewritten or consolidated, with the latest and current version being the Building Regulations 2010. The UK Government (at Westminster) is responsible for the relevant legislation and administration in England, the Welsh Government (at Cardiff) is the responsible body in Wales, the Scottish Government (at Edinburgh) is responsible for the issue in Scotland, and the Northern Ireland Execu ...

ISBEM
iSBEM is a free-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 emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and larg ...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 undergone additional programming to allow it to be used to produce 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 'Not a D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Performance Certificate
Energy performance certificates (EPCs) are a rating scheme to summarise the energy efficiency of buildings. In the European Union, EPCs are regulated by the European Directive on the energy performance of buildings. Turkey EPCs are mandatory when buying or selling property.

Directive On The Energy Performance Of Buildings
The Energy Performance of Buildings Directive (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. In 2021, the European Commission proposed to review the directive, with a view of introducing more exigent energy efficiency minimum standards for new and existing buildings, improved availability of energy performance certificates by means of public online databases, and to introduce financial mechanisms to incentivize banks to provide loans for energy efficient renovations. 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 p ...
