In the United Kingdom, a Seasonal Energy Efficiency ratio (SEER) for refrigeration and air conditioning products, similar to the ESEER but with different load profile weighting factors, is used for part of the Building Regulations Part L calculations within the Simplified Building Energy Model (SBEM) software, and are used in the production of Energy Performance Certificates (EPC) for new ...
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.
As a rating system, EPCs are known to have reliability issues. Non-domestic EPCs are found to have a regression effect where low-rated properties are more likely to obtain higher ratings in the renewal, while high-rated ones tend to get lower ratings. This directly casts doubts on EPC-based policies like Minimum Energy Efficiency Standards. [14]
Example EU energy label for a refrigerator. EU Directive 92/75/EC (1992) [1] established an energy consumption labelling scheme. The directive was implemented by several other directives [2] thus most white goods, light bulb packaging and cars must have an EU Energy Label clearly displayed when offered for sale or rent.
The term can also refer to a rating given to household goods sold in the EU. The rating shown on a label displayed at the point of sale. It is also a term relating to EU directive 2002/91/EC by which the energy efficiency of all buildings in England and Wales have to be stated when the building is sold as part of the Energy Performance ...
The House Energy Rating (HER) or House Energy Rating Scheme (HERS) are worldwide standard measures of comparison by which one can evaluate the energy efficiency of a new or an existing building. The comparison is generally done for energy requirements for heating and cooling of indoor space. The energy is the main criterion considered by any ...
The NHER rating takes into account the local environment and the effect it has on the building's energy rating. The NHER calculates the costs of space and water heating, but adds cooking, lights and appliances to give a comprehensive picture of energy usage in the home.
Although carbon emissions from housing have remained fairly stable since 1990 (due to the increase in household energy use having been compensated for by the 'dash for gas'), housing accounted for around 30% of all the UK's carbon dioxide emissions in 2004 (40 million tonnes of carbon) [1] up from 26.42% in 1990 as a proportion of the UK's total emissions.
