Assessing Energy Efficiency...
There are different ways to assess the energy efficiency of a building and there are different reasons for assessing it:
NON DOMESTIC ENERGY PERFORMANCE CERTIFICATES (EPC)
Measure the asset rating of the building, they are required by law for all buildings that are For Sale, To Let or newly constructed. The EPC's have to be displayed with the marketing particulars for a building and inevitably will be used more and more by potential occupiers to negotiate the basis of their lease or purchase.
DISPLAY ENERGY CERTIFICATES (DEC)
Measures and displays the actual consumption of energy in the building and how it is used – all buildings in the public sector over 500sqm are required to display the certificate in a public place - it is likely that it will become mandatory for all commercial buildings to have a DEC.
Energy audits are not regulated or mandatory in any way, but they simply report the way energy is used by an organisation and will reflect upon the factors that affect energy consumption highlighting high usage and making cost effective recommendations for reductions.
AIR CONDITIONING INSPECTIONS
Under the Energy Performance of Buildings regulations all air conditioning systems with an effective rated output of more than 12kW must be regularly inspected by an Energy Assessor.
NEW BUILD COMPLIANCE WITH SBEM AND SAP
All new buildings both residential and commercial are required to comply with the building regulations and in particular Part L, they need EPC certificates to demonstrate compliance.
Sets the standard for best practice in sustainable building design, construction and operation. A BREEAM assessment uses recognised measures of performance, which are set against established benchmarks, to evaluate a building's specification, design, construction and use. The measures used represent a broad range of categories and criteria from energy to ecology.
RENEWABLE ENERGY STRATEGIES
Renewable energy systems are varied and can be installed on new and existing buildings. With new building projects there is often a planning condition that needs to be discharged requiring the development to generate a percentage of the energy it consumes. With the introduction of Feed in Tariff's and the Renewable Heat incentive an income return can be generated from the installation of these technologies.
