What an Energy Performance Certificate is (EPC)?
The Energy Performance Certificate (EPC) gives information about the energy efficiency of the building to owners, prospective buyers and tenants. An EPC has two parts a graphic rating and a recommendations report.The rating is calculated based on the performance of the building and its building services such as heating, lighting, air conditioning. It is known as asset rating and begins from ‘A’ to ‘G’, which shows how energy efficient the building has been designed and modified. An ‘A’ rating indicates that a building is very efficient, consequently reduced fuel bills. Α ‘G’ rating shows an inefficient building with higher fuel bills. EPC has to be accompanied with a description of the potential rating of the building if all the proposed cost-effective measures are carried out. The age, location, size and condition of the building are taken into account for the production of an EPC and depending on these characteristics a building’s rating varies.
An Energy Performance Certificate (EPC) is required for every new building is constructed for application building permit or a building over 1000m2 is refurbished. A building is sold or rented requires an EPC for buyers or tenants.
What is the validation period of an EPC?
EPCs are valid for ten years but must be renewed if any modifications to the building are made.
Why air conditioning inspections are required?
The Air Conditioning System inspections are designed to maximize efficiency, reduce energy consumption, operating costs and the carbon emissions of the systems. The energy assessor will highlight improvements to the operation of existing systems or any opportunities to replace older, less energy efficient systems or oversized with new energy efficient systems.
When an Energy Audit should be taken place?
An Energy Audit benefits the energy consumption of your household/building and it is often conducted:
- When you think that your electricity/ fuel bills are high
- Before replacing energy consuming equipment such as windows, heating, air-conditioning and ventilation systems
- Before any changes in a household/building; renovation
- Before the installation of any Renewable Energy Systems
How often an Air Conditioning Inspection should be taken place?
All Air Conditioning systems with an effective output rated more than 12kW and more than 50kW total power in a building must be inspected. Air Conditioning systems with an effective output more than 12kW must be inspected 5 years after the installation and then one time every 5 years. Same with the Air Conditioning systems with total rated power in a building more than 50kW; the first inspection 5 years from the installation and one time in 5 years.
What an Air Conditioning inspection in a building is auditing for?
An Air Conditioning Inspection is undertaken in order to:
- Check the operation and efficiency of the AC system based on building’s needs
- Check the operation condition of refrigerant and cold water
- Check the operation of the system as concerns the air supply in the air conditioned spaces
- Check the operation and accuracy of control systems
