No

Aim

To recognise and encourage construction sites managed in an environmentally sound manner in terms of resource use, energy consumption and pollution.

Assessment Criteria

The following demonstrates compliance:

  1. Responsibility has been assigned to an individual(s) for monitoring, recording and reporting energy, water and transport consumption data resulting from all construction processes. To ensure the robust collection of information, this individual(s) has the appropriate authority, responsibility and access to the data required.

Energy consumption

One credit

  1. Monitor and record data on energy consumption (kWh) from the use of construction plant, equipment (mobile and fixed) and site accommodation necessary for completion of all construction processes.
  2. Using the collated data report the energy consumption (total kWh and kWh/£100k of project value) and carbon dioxide emissions (total kgCO2eq and kgCO2eq/£100k of project value) from the construction process via the BREEAM scoring and reporting tool.

Water consumption

One credit

  1. Monitor and record data on potable water consumption (m3) from the use of construction plant, equipment (mobile and fixed) and site accommodation necessary for completion of all construction processes.
  2. Using the collated data report the total net water consumption (m3), i.e. consumption minus any recycled water use, from the construction process via the BREEAM scoring and reporting tool.

Transport of construction materials and waste

One credit

  1. Monitor and record data on transport resulting from delivery of the majority of construction materials to site and construction waste from site. As a minimum this must cover:
    1. Transport of materials from the factory gate to the building site, including any transport, intermediate storage and distribution. Scope of this monitoring must cover the following as a minimum:
      1. Materials used in major building elements (i.e. those defined in BREEAM issue Mat 01), including insulation materials,
      2. Ground works and landscaping materials
    2. Transport of construction waste from the construction gate to waste disposal processing/recovery centre gate. Scope of this monitoring must cover the construction waste groups outlined in the project's site waste management plan (SWMP)
  2. Using the collated data, report separately for materials and waste, the total fuel consumption (litres) and total carbon dioxide emissions (kgCO2 eq), plus total distance travelled (km) via the BREEAM scoring and reporting tool.

Timber procurement

One credit

  1. Confirmation that all site timber used on the project is sourced in accordance with the UK Government’s Timber Procurement Policy.

Construction site management

One credit

  1. The principal contractor for the project operates an Environmental Management System covering their main operations. The EMS must be either:
    1. Third party certified, to ISO14001/EMAS or equivalent standard. OR
    2. The structure of the EMS is in compliance with BS8555 20031The British Standard BS8555; Guide to the phased implementation of an environmental management system including the use of environmental performance evaluation, April 2003 and has reached phase four of the implementation stage, ‘implementation and operation of the environmental management system’, and completed phase audits one to four, as defined in BS8555.
  2. Implement best practice pollution prevention policies and procedures on site, demonstrated through compliance with the items in the Environmental Checklist section 2.2.5 Preventing Pollution in the England and Wales Environment Agency’s ‘Building a Better Environment2Building a better environment, A guide for developers, Environment Agency, 2006, a guide for developers’

Description

CN1 

Factory gate. See criterion 6a See Relevant definitions

CN2 

Site timber. See criterion 8 For the purpose of assessing this issue, site timber is considered to be timber used to facilitate the construction process, this includes (but is not limited to) formwork, site hoardings and other temporary site timber. It does not cover timber materials installed within the building elements (this is addressed in BREEAM issue Mat 03 Responsible sourcing of materials).

CN3 

Site timber and re-usable formwork.

See criterion 8

Re-usable timber formwork itself does not automatically comply unless the timber was initially reclaimed, or it is sourced in accordance with the UK Government's Timber Procurement Policy.

CN4 

EA’s Environmental checklist. See criterion 10 The Environmental Checklist has been produced by the England and Wales Environment Agency as part of their publication ‘Building a Better Environment, a guide for developers’. The pollution prevention guidance contained therein is of relevance to sites in Scotland and Northern Ireland. In lieu of specific guidance from the Scottish Environmental Protection Agency and Northern Ireland Environment Agency, sites assessed in these countries must follow and demonstrate compliance with the E&W Environment Agency checklist.

CN5 

Reporting protocols (energy). See criteria 2 & 3

At present BREEAM sets no requirement on the use of a particular method or protocol for reporting energy/carbon from construction sites as there are currently no uniformly accepted protocols for the collection of data and assessment of emissions from construction sites (source: ‘Carbon: Reducing the footprint of the construction process, An Action Plan to reduce carbon’ (Strategic Forum and Carbon Trust, 2010).

A number of organisational carbon reporting protocols do exist and there are a number of initiatives underway to define construction-specific measurement and reporting protocols. Until such time as there is a consistent measurement protocol for reporting CO2/Energy from construction sites, BREEAM requires, as part of the reporting and certification process, confirmation of the methodology and/or protocol used for monitoring, collating and reporting data on construction site energy consumption.

CN6 

Target setting

At present data from construction sites do not generally exist in enough detail to set benchmarks and targets, BREEAM therefore does not set any requirements in terms of specific targets for reducing energy, water and transport consumption resulting from the construction process. Whilst BREEAM does not require them, it is strongly recommended that site specific targets are set and reported against.

Following adoption of widespread and consistent measurement and reporting protocols for construction site impacts and collation of construction site data, BREEAM is likely in future to establish consistent and complimentary targets as part of demonstrating compliance with this BREEAM issue (See also Additional Information section).

CN7 

Healthcare buildings (NHS sites) See criterion 9 As a prerequisite of awarding any of the available credits for this issue, the principal contractor must achieve the measure requiring operation of ‘an Environmental Management System’ (as defined above).

CN8 

Multi-residential developments with CSH assessed dwellings

For buildings with self-contained dwellings also being assessed under the Code for Sustainable Homes (CSH), the following applies:

Credits achieved under issue Man 3 of the CSH cannot be applied directly to issue Man 03 for assessments of multi-residential buildings. This is due to the different number of credits and additional issues assessed in BREEAM. Where specific criteria in this BREEAM issue, identical to that of the CSH, have been demonstrably achieved under a CSH assessment, then the CSH assessment and evidence of compliance can be used to assess and demonstrate compliance with the relevant corresponding criteria in this BREEAM issue.

Schedule of Evidence

Additional Information

Relevant definitions

Construction processes
  • The construction process includes the enabling works, assembly, installation and disassembly activities necessary for servicing the construction and completion of a new building3Carbon: Reducing the footprint of the construction process, An Action Plan to reduce carbon emissions, Joan Ko on behalf of the Strategic Forum and the Carbon Trust, July 2010.
  • Factory gate
    For the purposes of this issue, the factory gate is defined as being the product manufacturer gate (i.e. where manufacture and pre-assembly finishes and the material is in its final product form). Examples might include
    1. Steel/concrete/glass manufacturers for cladding, windows and beams etc,
    2. Quarry gate for aggregate and sand,
    3. Concrete plant for concrete and
    4. Saw mill and timber processing plant for timber

    Construction Excellence and reporting of construction site impacts

    Constructing Excellence publish the construction industry KPIs based on data collected by the Department for Business, Innovation and Skills via a voluntary quarterly survey returns by contractors throughout the UK. The Office of National Statistics also reports the annual results in the Construction Statistics Annual. One of the key performance indicators is the ‘amount of CO2 emissions caused by the energy used during the construction process per £100,000 of project value (kg CO2/£100k).

    Information collated by contractors as part of their voluntary submissions to Constructing Excellence may also serve to help demonstrate compliance with this BREEAM issue.

    The Strategic Forum for Construction 2012 Sustainability commitments

    The Strategic Forum for Construction has set up a task group to establish 2012 construction commitments aimed at achieving the following sustainability targets:

    1. Carbon: By 2012, a 15% reduction in carbon emissions from construction processes and associated transport compared to 2008 levels.
    2. Water: Water usage in the manufacturing and construction phase reduced by 20% compared to 2008 usage
    3. Responsible Sourcing: 25% of products used in construction projects to be from schemes recognised for responsible sourcing.
    4. Waste: By 2012, a 50% reduction of construction, demolition and excavation waste to landfill compared to 2008.
    5. Biodiversity: All construction projects over £1m to have biodiversity surveys carried out and necessary actions instigated

    In July 2010 the Strategic Forum and the Carbon Trust published an action plan to reduce Carbon Emissions resulting form the construction process4Carbon: Reducing the footprint of the construction process, An Action Plan to reduce carbon emissions, Joan Ko on behalf of the Strategic Forum and the Carbon Trust, July 2010. Specifically the plan identified the following actions/next steps:

    1. Work with stakeholders to produce a protocol for assessing greenhouse gas emissions from construction processes and associated transport.
    2. Develop good and best practice benchmarks for construction site energy consumption (e.g. thresholds for tonnes CO2 per m2 gross floor area or £100,000 project value).
    3. Provide BREEAM and CEEQUAL credits for demonstrated good and best practice based on the defined benchmarks.

    Once established, BREEAM is likely to require monitoring and reporting of energy consumption in accordance to the proposed new protocol and set targets for meeting or exceeding good and/or best practice benchmarks for energy and transport use.

    Tools for monitoring and targeting construction site impacts

    ‘smartER’ is a new add-on to BRE’s online site waste management planning tool SMARTWaste Plan. ‘smartER’ enables existing and new SMARTWaste users to capture, monitor and target a project's onsite energy consumption, and therefore CO2 footprint, water consumption and responsible sourcing of timber. The system can be used as a tool to help meet the criteria of this issue and as a source of evidence for demonstrating compliance. www.smartwaste.co.uk/
