Energy Efficiency

Energy Efficiency is the reason for the existance of Part L of the Building Regulations it is an approved document so must be followed. Both new and existing buildings are covered and it targets 'Heat Loss' - 'Air Leakage ' - 'Solar Gain' - 'Efficiency of Heating & Cooling Systems' which includes central heating boilers and controls, hot water storage & controls. Covers energy efficiency and requires minimum SEDBUK ratings of appliances whether for new or replacement installations. Note, when a replacement boiler is installed it is required that the entire system is brought up to the energy efficiency requirements of a new system. SAP = Standard Assessment Procedure. TER = Target CO2 Emission Rate.

How does energy use impact on the Environment? 
Most of our energy is derived from burning fossil fuels, either directly in the home or indirectly in power stations. About 98% of energy demand is produced by burning coal, oil, peat, or natural gas. Energy use can have many and varied detrimental impacts ... [ read more ]
What are Fossil Fuels? 
Many millions of years ago growing land-plants and algae in the sea took energy from sunlight; the fish & other animals ate the plants; when the plants & animals died they became buried in mud and fossilised. Under intense pressure and heat deep ... [ read more ]
What are Micro CHP Systems? 
CHP (combined heat and power) is a very efficient technology for generating electricity and heat simultaneously, by using conventional generation technologies, fuel cells or ‘stirling’ engines within a CHP ‘plant’. The heat generated in the process is ... [ read more ]
What Is Renewable Energy? 
Renewable energy comes from energy resources that are continuously replenished through the cycles of nature. Unlike fossil fuels, their supply will never become exhausted. The main sources of renewable energy are the sun (solar energy), the ... [ read more ]
What is Micropower or Microgeneration? 
Micropower, or Microgeneration is the production of energy on the smallest of scales, for individual buildings or communities. Micropower technologies emit low amounts of carbon dioxide(CO2), or in some cases, no carbon dioxide at all, whilst ... [ read more ]
Why do we need Microgeneration? 
Microgeneration is cost-effective. Some of Micropower technologies are more accessible than others but all can deliver on at least two of the four energy policy objectives; reductions in C02 emissions, reliability of supply, fuel poverty relief and ... [ read more ]
