What Are The Types Of Energy Performance Certificates?
There are various parameters available to classify the Energy Performance Certificates into different categories. Broadly speaking, there are two types of Energy Performance Certificates available – domestic and non-domestic. There are some who classify it into consumption certification and requirement certificate. It is important to understand the differences so that you can understand the type of EPC you need to possess. Accordingly, you can contact professional service providers like EPCChoice to get what you need.
Consumption Vs Requirement –
The consumption certificate is required when you have already consumed energy for the last few years. The consumption of energy will depend on the habits of the occupants. On the other hand, the requirement certificate is based on the energy requirement of a building. It is more of an estimation and it is not dependent on the energy consumption of the occupants. In fact, it is done by an experienced energy consultant on site before producing an EPC.
Such an expert takes into consideration the condition of the building structure, heating system, and various such factors before making an estimation. It is somewhat dependent on the owner as to which certificate they will opt for. But there are certain cases where the requirement or the consumption certificate is mandatory. For example, the requirement certificate is necessary for those buildings which are no renovated and have up to four residential units. Moreover, if the consumption data is not available, the requirement certificate is the only option to opt for. But the owner needs to have at least one of them as per the law of the land.
Domestic Vs Non-Domestic –
Home inspectors or Domestic energy assessors apply different standards to estimate or calculate the energy rating of a residential domestic building. The certificate will contain the property address, property type, certificate date and serial as well as total floor area. The rating is given in the scale of A and G. Different countries have different requirements like the domestic buildings need to have D or E rating for residing legally. If not, modifications have to be made and the recommendations on the EPCs have to be followed thoroughly to re-inspect and get an upgrade in rating for safe residing.
It is needless to say that commercial property needs EPCs even before owners can rent it out to the potential buyers. The rating scale varies from A to G and sometimes it is also given in number where the number represents the percentage of CO2 emission.
