Part L2A Building Regulations Compliance Reports

To the latest Building Regulations, we are able to provide Part L2 reports for new buildings. Using software, we are able to create a dynamic thermal simulation model of the building in order to estimate its energy loads and carbon emissions. A BRUKL report (Building Regulations UK Part L Report) is generated by the software which can then be forwarded to Building Control in order to demonstrate the buildings compliance.

Part L2B Building Regulations Compliance Reports

Similar to Part L2A but for existing buildings being modified, we are also able to produce reports to satisfy Part L2B of the building regulations. We can also investigate the project to determine if consequential improvements will be required, if so which would be the most beneficial to the building and what would the estimated payback time would be.

Energy Performance Certificates

We can produce Energy Performance Certificates (EPC’s) for any sized commercial building either newly built or existing.

Display Energy Certificates

We can produce Display Energy Certificates (DEC’s) for any sized commercial building.

Planning Policy Statements

When applying for planning permission local councils will often request that either an amount of the buildings proposed energy use must come from a renewable source or that they must improve upon the building regulations by a further % carbon reduction. Using our computer simulation of the building we can estimate the buildings current usage and investigate the most cost effective way of meeting these requirements.

Overheating Calculations

Unsure if your building will require cooling in order to remain at a reasonable working temperature, let us carry out overheating calculations for you. We are also able to undertake overheating calculations for Schools and Colleges in order to demonstrate compliance with BB 101.

Natural Ventilation Calculations

We are able to carry out natural ventilation calculations in order to show compliance with Part F of the building regulations. Depending on the complexity of the room we may carry these calculations out either by hand or by using the EDSL TAS software. Once the calculations are complete we will compile a report that can be submitted to building control in order to demonstrate compliance.

Daylighting Calculations

Daylighting calculations are typically carried out under BREEAM (Building Research Establishment Environmental Assessment Methodology). We are able to produce daylight analysis grids for the whole building and then calculate the average daylight factor within a room and the uniformity of daylight, as well as other values such as the minimum and maximum areas of daylight. We can then prepare BREEAM compliant reports to submit to your BREEAM Assessor.

Peak Loads Analysis

Using the model of a building we are able to run a number of different simulations, for example we can set the external temperature to a constant value of -4ºC and calculate what the peak heating load would be for the building. We can run similar simulations to determine the peak cooling load, solar gain, ventilation rates etc.

IES VE

Thermal Analysis Software is a piece of 3D dynamic thermal modelling software that we use in order to carry out a range of our energy services.

Starting from architects drawings, we input the building to its exact size and shape within the 3D modelling software. Once input within the software program we can further enhance the model, giving it design features such as brickwork or grass within Google Sketch Up modelling package.

Once the 3D model is complete, we begin the input the specific details of the building and its services. Such as the construction U-values, Boiler efficiencies, cooling COP’s, renewable data etc. The software then simulates this model throughout a year using exact weather data for its proposed location, for example London.

We can then investigate how the building is likely to perform and adjust the details in order to make it as efficient as possible. Once the final design of the building is agreed upon we will produce the BRUKL document to demonstrate compliance with Part L to building control and finally an Energy Performance Certificate.
