Glossary of Terms

ASHP (Air source heat pump)

This product uses the ambient air outside, heats it up and draws it into the home to provide an efficient alternative heat source.

 

BIOMASS

The production and use of natural and sustainable fuels such as pellets and wood for domestic heating. Ideal for areas dependant on LPG or oil.

 

Building Regulations Part L

(1a) (The conservation of fuel and power)

Part of the building regulations used to establish the SAP rating (standard assessment procedure) of a dwelling which is now used to determine the minimum energy efficiency of a dwelling for the purposes of allocating a code level rating under the code for sustainable homes.

 

Building Regulations Part E

(Resistance to passage of sound)

This part of the building regulations addresses the need for sound insulation and has three main aspects:

  1. Walls of dwellings should be resistant to the transmission of sound;

  2. Floors and stairs in flats should be resistant to the transmission of sound from below;

  3. Floors in flats should be resistant to the transmission of impact sound from above.

 

CHP (Combined Heat and Power)

is the simultaneous generation of usable heat and power (usually electricity) in a single process. It is a highly efficient way to use both fossil and renewable fuels.

 

COC (Chain of Custody)

The chain of custody refers to the unbroken and documented chain of ownership of timber all the way from the original source in the forest, via the mill, the importer and the supply chain right through to the end customer.

 

CSH (The code for sustainable homes)

Building regulations introduced in 1997 and made mandatory with effect from April 2008. Ensuring that future home building meets the environmental needs for the future.

 

FiT (Feed in Tariff)

is a Government incentive scheme for renewable energy systems that generate electricity.

 

FSC (forestry stewardship council)

is an internationally recognised organisation that has developed a system of forest certification and product labelling that allows consumers to identify wood and wood-based products from well-managed forests.

 

GSHP (Ground Source heat pump)

This product uses the natural heat and energy from the ground to provide whole house heating requirements.

 

HRS (Heat Recovery System)

A heat recovery system is designed to completely change all the air in the property at least once every two hours, continually replacing the stale damp air with fresh, warmed, clean, filtered air. The system can recover up to 60-70% of the heat normally lost through trickle vents and other breakout points in the building structure.

 

MCS (Microgeneration Certification Scheme)

An internationally recognised accreditation mark that provides consumers with the confidence of knowing that the installers and the products installed have been approved under the scheme.

 

PEFC (Programme for the Endorsement of Forest Certification schemes)

is an independent, non-profit organisation which promotes sustainably managed forests through independent third party certification. It provides an assurance mechanism to purchasers of wood and paper products that they are promoting the sustainable management of forests.

 

RHI (Renewable Heat incentive)

A government incentive scheme for specified renewable energy systems that produce heat.

 

SAP ratings (Standard assessment procedures)

These are based on the energy costs for space and water heating. They establish a means for both the home owner and purchaser to understand the running costs and environmental impact of the property. In our current climate these constitute strong selling and marketing points for all homes. The SAP rating is a legal requirement enforced by the government through building control to be applied to all new dwellings.

 

SEDBUK (Seasonal efficiency of domestic boilers)

SEDBUK stands for "Seasonal Efficiency of Domestic Boilers in the UK", and is an industry standard for measuring and publishing the thermal efficiency of a boiler. This is so the public can compare the economy of various makes and models of boiler on the same fair basis.

 

SUDS (Sustainable drainage systems)

This considers the long term environmental and social factors in decisions about drainage. It looks at the quantity and quality of runoff, and the reuse of surface water in the urban environment. Many existing urban drainage systems can cause problems of flooding, pollution or damage to the environment and are not viewed as sustainable.

 

Solar Thermal

This refers to the harnessing of the suns power through the use of solar collectors for the purpose of providing hot water to the home. A very efficient and cost effective solution for the home.

 

Solar Photovoltaic (PV)

This relates to the suns power being harnessed through the use of solar collectors for the purpose of providing and alternative domestic electricity supply.

 

VOC (Volatile organic compounds)

VOC's are the solvents used to carry the colouring (pigment) in the paint. As the paint dries the VOC's evaporate producing that 'newly painted' smell.

 

WRAS (Water regulations advisory scheme)

WRAS promotes knowledge and assessment of the Water Regulations throughout the UK. It encourages consistent interpretation and enforcement, for the prevention of waste, excessive consumption, misuse, erroneous measurement or contamination of water.
