Energy Performance Certificates (EPCs) are now essential for offices and commercial buildings in London, and those who do not comply will face a fine.
The certificates can lead to cost benefits as they highlight where savings in energy can be made by the owner.
Alex Matthias, energy management leader at RSA said: “The owner of a 7,000 msq building carried out a full energy audit of its air conditioning unit after completion of an energy performance certificate which highlighted the air conditioning unit was inefficient.
“The cost to improve the air conditioning unit was £31,900, which would result in a saving of £27,000 per year and an annual reduction of 126,700 KG CO2.”
EPCs are now needed whenever a building is built, sold, or rented out be it for commercial or residential purposes.
Basic information required by the auditors is building size, total usable floor area, and an up to date operation and maintenance manual.
