NHER

The NHER (National Home Energy Rating) is a method of assessing the energy performance and fuel cost of a dwelling. It uses a similar data set to SAP but includes more detail on occupancy, location and appliance use to give a more accurate calculation of CO2 emissions and running costs for a specific dwelling. The NHER rating is not a statutory requirement. It is often used by affordable housing providers to give a good indication of potential running costs of new properties - view »

EPC

The Energy Performance Certificate is produced upon completion of the dwelling after an air leakage test has been performed. It is required to be included in the Home Information pack (HIP). It will account for any changes made to the original construction specification which can occur during construction or after the PEA was produced. The rating is a measure of the building's overall energy efficiency and its environmental impact, calculated in accordance with a national methodology. It takes into account factors such as insulation, heating and hot water systems, ventilation and fuels used. The average Energy Efficiency Rating for a dwelling in England and Wales is band E (rating 46).

Buildings that are more energy efficient use less energy, save money and help protect the environment - view »

Air Leakage Testing

The air-tightness of a building is known as its 'air permeability' or leakage rate. Air leakage can occur through gaps, holes or cracks in the fabric of the building envelope which are not necessarily visible to the naked eye. Air leakage will affect a buildings Co2 emission rate and forms an integral part of the calculation procedure contained within Part L of The Building Regulations - view

Code for Sustainable Homes

Besblock now has 4 licensed Code for Sustainable Homes Assessors. The Code is a development of the Eco Homes scheme and is administered by the BRE. It measures the ecological, environmental sustainability and energy efficiency credentials of individual properties within a housing development. A Code assessment looks in detail at various aspects of the development encompassing;  Energy use, Transport, Materials in use, Pollution, Water use, Health and Well being, Ecology, Construction Management. Code assessments are required for all Housing Corporation funded schemes and such schemes are required to meet the level 3 category - view »
