Importance of EPC Certificate for a Building – London Property Inspections

An energy assessment of the commercial performance of a building is a complex calculation based on a combination of factors. Importance of EPC Certificate for a Building – Try London Property Inspections for all kind of landlord safety and EPC certificate London. The most important factors are:

  • Perform a detailed study of the site, measure and quantify the external details of the building’s fabric and calculate the thermal performance of the materials used, such as the roof, floors, walls and glazing. (Just like Chartered Quantity Surveyors we do this very well)
  • Identify and measure the gross internal floor area (GIFA) and program the relevant activity floor areas (zones) of the building that are used for different purposes, p. Celled offices, open office, meeting rooms, common areas, etc. Each zone has completely different taxes / energy requirements.
  • Perform a detailed investigation and investigate the energy performance of the central heating installation, air conditioning systems (cooling), ventilation (supply and extraction), hot water generation and lighting systems used within each of the activities (zones) throughout the entire building.

The energy performance of a commercial property is represented as an index based on CO2. The qualification of co2 that a building receives depends on the age in the building, the type of activities taking place in the building, the construction of the external structure of the building, the energy fuels used in the building, such as electricity, gas and oil, including renewable energy sources. technologies, the energy performance of space heating (central heating), water heating systems, air conditioning, ventilation and the performance of ballasts and lighting lamps, minus the energy generated by the energy generation technology installed in the building (such as solar water heating), PV) . The lower the number, the lower the typical CO2 emissions (based on a scale from zero to 150+). The classification is adjusted for the gross area of ​​the internal floor of the building, so that it is independent of the size for a certain type of building.

Gather the required information for an EPC

After the energy evaluate has been instructed to produce an EPC, there are three

key steps to perform the evaluation. These are:

  • collect relevant information about the building; this is done by visiting the building and carrying out an inspection of the site. (This is a mandatory requirement)
  • analyze the information and identify different parts of the building
  • Go back to the office and enter the collected information from the site survey into an approved commercial software program.
  • Data entry and modeling of a general commercial building require two or three times the time spent on the site to perform the site inspection, that is, a half-day inspection on the site can take an extra day to complete the Data entry. The software program and modeling of the build in a government-approved 3D software simulation program.

The energy elevator must understand the internal design of the building and for what purposes / activities are performed within each zone or for the new construction for which they are designed to be used.

The information needed to produce an EPC includes:

  • analyze the information and identify different parts of the building and its dimensions (either as verified from the plans or measured). This information can easily be provided from building plans.
  • activities carried out within the zones, p. Commercial space, office space, kitchens, storage, etc., since each zone has completely different loads / energy requirements.
  • Heating and ventilation for each zone, including the type of system, measurements, controls, used fuels, etc.
  • Lighting systems such as ballasts, lamps and controls used for each zone
  • The construction of the structure of the building and the thermal performance of the materials used: roof, floors, walls and glazing. If there are no plans for a building, the energy evaluator must inspect the building and collect the correct information.

    If you have updated information and plans for its construction, this process takes less time. The commercial energy consultant is responsible for the accuracy of the information used in the energy calculations and even when detailed plans are available for existing buildings, you must validate this information by inspecting the site.
