EPC companies guide you on how to improve energy efficiency of your home. The EPC focuses on the amount of energy efficiency of any building be it your house or used for commercial purpose. An energy performance certificate is offered by an accredited Energy Assessor of high standards. He or any approved Data Collector will first conduct a site survey before offering you an energy certificate.
They will consider various factors such as ventilation, air conditioning, buildings fabric, heating, lighting efficiencies and how these elements are controlled. They will then rate energy efficiency of your house on a scale of A to G, where in A stands for highest level and G which is poor score. In addition to this, they have to provide a recommendation letter on how to improve energy efficiency. In case of a commercial building these certificates are valid only for 10 years and have to renewed again unlike houses.
There are a volley of factors to be considered while calculating the ratings for an EPC for every home, as each house is unique. However, the basic ones used for energy assessments are:
Age of the building
Building Construction itself
Solar panels, domestic wind turbines and other renewable energy sources
Heating and controls methods used
Type of windows and its number
Volumetric calculation of all floors
Levels of insulation(includes lofts and walls)
Fixed lighting efficiency
Thermal properties of adjacent buildings
Based on these recommendation, a house owner can carry out suitable modifications and improve the value of the house. It is said that such certificates are compulsory when a landlord decides to let out his property or puts it on sale. It is an important document which is compulsorily added in a home information pack(hip). Dependent on these details a tenant or a buyer makes an informed decision and then carries out the transaction with the landlord. Some companies also offer energy advice for home buyers and sellers, private landlord. If you are a home seller and are considering property lettings in future, then you have to have such certificates to determine your houses performance on energy.
An accredited energy assessor will carry out the survey and an overall assessment if your house based on a sliding scale of A to G. As said earlier, A is the highest level (i.e. most efficient) and G (less efficient). Later on, simplified form of rating was used which is on the similar lines of freezers, fridge and other home appliances.
