BREEAM

We provide the evidence and assessment services for HEA and ENE BREEAM credits.

 

Assessments can be undertaken using either SBEM or DSM methodology.

What information do we require?

As with any calculation based upon a Part L2A assessment – the calculated data is only as good as the data input into it. As a compliance assessment, a number of factors are prescribed, resulting in outcomes which may deviate significantly from those achieved in practice. If a more concise understanding of CO2 emission reductions or energy demand is required, it is recommended to carry out a design evaluation via a bespoke thermal simulation.

Note, for shell and core / design stage buildings, as a minimum we require only floor plans and elevations to produce either an EPC or an SBEM report. However, any M&E specifications or U values that have been recommended (in the absence of any information provided) within the calculations should be implemented as a minimum during fit out.

We determine what information you need to provide on a case by case basis, usually this is established with a short telephone conversation and email exchange either prior or after appointment.

 
 

BREAM ENE 01 "Energy - Reduction of Energy Use and Carbon Emissions"

The aim of ENE01 is to recognise and encourage buildings designed to minimise operational energy demand, consumption and CO2 emissions.

The assessment is based upon the ‘Brukl.inp’ file that we will produced within a Part L2A compliance assessment and will consider the following criteria:

  • The building’s operational energy demand

  • The energy delivered (consumption)

  • The total resulting CO2 emissions

The calculation is determined by modelling the building’s specified/designed regulated fixed building services. 

  • Building floor area (m2)

  • Notional building energy demand (MJ/m2)

  • Actual building energy demand (MJ/m2)

  • Notional building energy consumption (kWh/m2)

  • Actual building energy consumption (kWh/m2)

  • Target Emission Rate (kgCO2/m2)

  • Building Emission Rate (kgCO2/m2)

 

BREAM ENE 04 "Energy - Low and Zero Carbon Technologies"

 

The aim of BREEAM Ene 04; ‘Energy - Low and Zero Carbon Technologies’ is to reduce carbon emissions and atmospheric pollution by encouraging local energy generation from renewable sources to supply a significant proportion of the energy demand.

This issue is split into two parts:

  • Passive Design (2 credits).

  • Low or zero carbon technologies (1 credit).

 

BREAM HEA 01 "Health & Wellbeing - Visual Comfort"

 

The aim of BREEAM Hea 01; ‘Health and Wellbeing - Visual Comfort’ is 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.

Greenlite offer daylight assessment services suitable for assessing compliance with the ‘daylighting’ elements of this BREEAM credit.

For this, we use the Energyplus module of DesignBuilder to simulate radiance daylight factors, diversity ratios and sky view metrics.

BREAM HEA 04 "Health & Wellbeing - Thermal Comfort"

 

The aim of BREEAM 2014 Hea 04; ‘Health and Wellbeing – Thermal Comfort’ (formally Hea 03 under BREEAM 2011) is to ensure that appropriate thermal comfort levels are achieved through the design of the building. This includes elements subject to a thermal simulation and the specification of suitable controls, in order to ensure the thermal comfort of building occupants.

Thermal comfort for naturally ventilated and air-conditioned buildings is modelled using the EnergyPlus (Designbuilder) software and includes including thermal modelling and design for future thermal comfort.

Under BREEAM 2014, for all buildings, Hea 04 is now subject to CIBSE Guide A or a relevant industry standard, and predictive mean vote (PMV) and percentage of people dissatisfied (PPD) metrics against ISO 7730:2005. For non-mechanically cooled buildings, CIBSE TM52 is also a requirement

 
 

Pricing and Lead-Time

 

We will provide a fixed price quote depending upon the only credits required. 

 

In good faith we include in our pricing unlimited telephone/video/email consultancy and iterations of each simulation until the desired result is achieved.

As soon as we have been provided with the data we will begin work, typically either the same or the next working day. Allow two working days for the issue of the first reports.

Example, .inp file and BER<TER BRUKL Output Document (SBEM) for 2000m2 Office, £350 (includes Design Stage Building Control sign off SBEM calcs).
