While forming the basis of the European standard for calculating environmental impacts of buildings (EN 15978:2011), LCA is now rapidly propagating into the industry, as can be seen with its incorporation into BREEAM, BREEAM International, and LEED. eTool is able to provide software and training within your organisation, enabling you to either conduct your own LCAs or our engineers can consult with your team to complete LCAs for your project. The points awarded are cost competitive with other categories, particularly when aiming for higher rating levels.

BREEAM 2011/2014

2 Exemplary MAT01 materials credits (13.5% weighting) awarded for using IMPACT compliant eToolLCD. These credits can be awarded alongside the traditional credits for using the Green Guide to Specification.

Compliance evidence requirements

  • a copy of the LCA model cloned into BRE eTool account (eTool will complete this on certification of the model and email confirmation will be sought)
  • Results table summary (automated from the tool)
  • A short qualatitive statement highlighting what stage the LCA was completed in and how it did or did not improve environmental performance
  • A completed BREEAM LCA scope document

1 MAT06 materials credits (13.5% weighting) awarded for completing a materials efficiency analysis at concept design (RIBA stage 2).

Compliance evidence requirements

  • Report highlighting opportunities and measures implemented to reduce volume of materials used in construction.

3 Management credits (Man 05 2011, Man 02 2014) available (12% weighting) for undertaking an ISO 15686 compliant life cycle costing analysis. 1 credit is awarded if completed at feasibility stage, a further credit is awarded if the analysis demonstrates improvements in life cycle costs and the final credit is awarded if the analysis is updated throughout RIBA stage D/E the design.

Breeam 2011 – 4 Energy (Ene 04) credits available (19% weighting) for undertaking a life cycle assessment of the chosen low/zero carbon technology in accordance with ISO 14044. The first 2 credits are awarded for completing the study. If the study indicates a performance improvement of 10-20% 3 credits are awarded or if the improvement is over 20%, 4 credits are awarded.

BREEAM International 2013

6 Materials (Mat 01) credits available (12.5% weighting) for completing a life cycle assessment. eToolLCD complies with all assessment and data requirements (as detailed in the Mat01 V3.0 calculator spreadsheet) and can be used to award the full 6 credits.

3 Management credits (Man 05) available (12% weighting) for undertaking an ISO 15686 compliant life cycle costing analysis. 1 credit is awarded if completed at feasibility stage, a further credit is awarded if the analysis demonstrates improvements in life cycle costs and the final credit is awarded if the analysis is updated throughout RIBA stage D/E the design.

2 Energy (Ene 04) credits available (19% weighting) for undertaking a life cycle assessment of the chosen low/zero carbon technology in accordance with ISO 14044.

BREEAM UK Refurbishment and Fit-out 2014

6 Materials credits (12.5% weighting) can be awarded where the project uses an IMPACT compliant life cycle assessment (LCA) tool to measure the life cycle environmental impact of the refurbishment or fit-out works.
2 Management credits (12% weighting) can be awarded when an elemental life cycle cost (LCC) analysis has been carried out at Process Stage 2 together with any design option appraisals in line with ‘Standardised method of life cycle costing for construction procurement’ PD 156865:2008

Home Quality Mark

There are two ways of assessing element 19 – Environmental Impact from Construction Products.  The foundation method which uses a Bre spreadsheet to award up to 8 credits or the comprehensive IMPACT compliance route which awards up to 23 Credits for completing an LCA.

18 Life Cycle Costing credits are also available for undertaking LCC analysis from RIBA stage 2 and providing an simple LCC report for the homeowners.

CEEQUAL 2014 V4.1

4 Client points and 10 design points can be awarded for adopting a whole-life approach to environmental aspects of the project. An eTool assessment is able to competently demonstrate this.
