As LCA of the built form rapidly propagates as a standard component of sustainable design ,most of the “Green Building” rating schemes around the world have have begun to are have already integrated LCA into their credits and systems. eToolLCD meets the requirements of many schemes globally and has been successfully utilised to improve the rating performance for multiple large projects.

If your project is seeking to achieve a certification not listed, please get in touch to discuss how our expert building LCA team can help.


Level(s) is a sustainability reporting framework with 3 broad categories

  • Level 1 Common performance assessment – simple and accessible
  • Level 2 Comparative performance assessment – making comparisons against functionally equivalent buildings (such as eTool Benchmarks)
  • Level 3 Performance optimisation assessment – Completing detailed assessment and analysis of design options to improve performance

Against each category, the following “macro-objective” indicators are measured

  1. Greenhouse gas emissions along a buildings life cycle
  2. Resource efficient and circular material life cycles
  3. Efficient use of water resources
  4. Healthy and comfortable spaces
  5. Adaptation and resilience to climate change
  6. Optimised life cycle cost and value

eTool is perfectly set-up to report against those shown in bold

  1. We have long had fully automated reporting to EN15978 (required for our Green Star work). Our peer-reviewed reports cover everything required for an EN15978 compliant LCA from goal and scope to cut-off rules, performance against benchmark and design improvement recommendations. An example EN15978 report can be found here.
  2. Our design life cycle inventory and materials summary reports provide detailed breakdowns of materials used in the LCA/LCC, their quantities and categorisation.
  3. The unique template system used in eToolLCD means that ISO15686 compliant life-cycle cost analysis can be undertaken by switching on our recently established cost datasets.

eTool applaud the framework defined in Level(s) following the now long established methodology of EN15978 – Sustainability of construction works.

BREEAM International

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.

Living Building Challenge

The US-based Living Building Challenge (LBC) is a building certification program, advocacy tool and philosophy that aims to rapidly diminish the gap between current limits and the end-game positive solutions we seek.

The Challenge is comprised of seven performance categories called Petals: Place, Water, Energy, Health & Happiness, Materials, Equity and Beauty. Petals are subdivided into a total of twenty Imperatives, each of which focuses on a specific sphere of influence.

Under the “Materials” petal, proponents are required to conduct an “Embodied Carbon Footprint” and eToolLCD is currently listed as one of three recommended tools to meet these strict requirements.

BioRegional – One Planet Living

The One Planet Living approach and ten principles framework is a simple way to plan, deliver, communicate and mainstream sustainable development and the green economy.

eToolLCD is able to assist you in quantifying and improving your project in regards to the the principles required to achieve a “One Planet” outcome.

UDIA – EnviroDevelopment

EnviroDevelopment is a scientifically-based branding system designed to make it easier for purchasers to recognise and, thereby, select more environmentally sustainable developments and lifestyles. Facilitated by the Urban Development Institute of Australia, EnviroDeveloment has embraced LCA as  way of genuinely quantifying the impacts of a property development to obtain the “Materials” credit within the scheme.

German Sustainable Building Council – DGNB

The German Sustainable Building Council (DGNB – Deutsche Gesellschaft für Nachhaltiges Bauen e.V.) was founded in 2007 by 16 initiators from various subject areas within the construction and real-estate sectors. The aim was to promote sustainable and economically efficient building even more strongly in future.

Life Cycle Assessment forms a core component of the “Environmental Quality” Catalogue and eToolLCD is in the process of gaining compliance with the DGNB LCA requirements.
