BREEAM (Building Research Establishment’s Environmental Assessment Method) is a sustainable rating scheme for buildings. The BREEAM assessments aim is to minimise the environmental impact of any new buildings or refurbishments by using a scoring system based on 9 criteria.
A certain number of credits are available under each of the criteria, which are then multiplied by a weighting factor to get an overall score and BREEAM rating. The BREEAM ratings available include: Unclassified, Pass, Good, Very Good, Excellent and Outstanding.
Local Authorities may ask for new buildings to meet a specific BREEAM rating such as Very Good or Excellent within their planning requirements. At Ecodraw we can produce a number of reports, calculations and statements to help your BREEAM Assessor produce their overall BREEAM Report and achieve your target rating.
Here are some of the BREEAM credits we are able to help you achieve:
Aim: To ensure daylighting, artificial lighting and occupant controls are considered at the design stage to ensure best practice visual performance and comfort for building occupants.
At Ecodraw we can carry out daylight calculations of your proposed building to determine each rooms average daylight factor, uniformity ratio and room depth criterion to determine if you will receive the BREEAM credits.
Aim: To recognise and encourage a healthy internal environment through the specification and installation of appropriate ventilation, equipment and finishes.
If your building is to be natural ventilated we can produce a natural ventilation simulation of your building based upon the opening windows or vents that you specify. This allows you to see exactly where the fresh air will enter your building and where the stale air will exit.
We will compare the natural ventilation rate of your building against the criteria of relevant standards such as BB101, CIBSE Guide A or Part F to determine if you will receive the BREEAM credit.
Aim: To ensure that appropriate thermal comfort levels are achieved through design, and controls are selected to maintain a thermally comfortable environment for occupants within the building.
At Ecodraw we will produce a Dynamic Thermal Model of your proposed building in order to accurately simulate the internal temperatures of the building and assess the amount of overheating.
We can then compare the results against industry standards such as BB 101, TM 52 or CIBSE Guide A to determine if your building will meet these standards and therefore receive the credits available through BREEAM.
Aim: To recognise and encourage buildings designed to minimise operational energy demand, primary energy consumption and CO2 emissions.
Using your plans and design specifications we will produce a Dynamic Simulation Model of your proposed building to generate the buildings typical carbon emissions. We can then determine if your building would satisfy the Part L Building Regulations and based upon its amount of carbon reduction, how many BREEAM credits it will receive.
Aim: To encourage the adoption of design measures, which reduce building energy consumption and associated carbon emissions and minimise reliance on active building services systems.
Buildings can receive a BREEAM credit if they can show that the building uses passive design measures to reduce its energy demand, such as using natural ventilation and free cooling methods to satisfy the thermal comfort of the occupants in Hea 04. A BREEAM credit is also available if a Low and Zero Carbon Technology feasibility study has been carried out by the Concept Design Stage.
At Ecodraw we can produce reports to show the ways in which your building will utilise passive design and how much energy will be saved by doing so. We can also assess your building and the site for the feasibility of any low or zero carbon technologies. We will determine what LZC technologies would be the most economical and practical to install, and carry out life cycle assessments for each.
Aim: To contribute to a reduction in national NOx emissions levels through the use of low emission heat sources in the building.
Any plant installed within a building for the generation of either heating or hot water must have a low NOx emission rating in order to receive a BREEAM credit. More credits are available depending on how low the NOx emissions are. If there are multiple sources of heating or hot water plant then an average NOx emission rating for the building should be determined.
At Ecodraw we can look at the proposed specification for your buildings heating and hot water generation plant and determine the amount of NOx emissons. If we find that the NOx emissions are too high to receive the BREEAM credit we can recommend alternative plant equipment with lower emissions to help receive the credit.
Although we are not fully qualified BREEAM assessors at Ecodraw, we only produce calculations, simulations and reports to achieve specific credits, we have worked with a number of experienced BREEAM assessors in the past and therefore if you would like us to find a BREEAM assessor for you we would be more than happy to do so.
