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 below or on our Green Star or UK Rating Schemes pages, please get in touch to discuss how our expert building LCA team can help.
LEED V3 and V4
Within Option 4. Whole-Building Life Cycle Assessment, 3 points are available for completing a life cycle assessment and demonstrating a 10% reduction in in at least three environmental impact categories (listed below) and with no impact category to increase by more than 5%.
The reference and design buildings must be of comparable size, function, orientation, and operating energy performance as defined in EA Prerequisite Minimum Energy Performance. The service life of the reference and design buildings must be the same and at least 60 years to fully account for maintenance and replacement. Use the same life-cycle assessment software tools and data sets to evaluate both the reference case and the design case, and report all listed impact categories. Data sets must be compliant with ISO 14044. Select at least three of the following impact measures for reduction: global warming potential (greenhouse gases), in CO2e; depletion of the stratospheric ozone layer, in kg CFC-11; acidification of land and water sources, in moles H+ or kg SO2; eutrophication, in kg nitrogen or kg phosphate; formation of tropospheric ozone, in kg NOx or kg ethene; and depletion of nonrenewable energy resources, in MJ.
- global warming potential (greenhouse gases), in CO2e;
- depletion of the stratospheric ozone layer, in kg CFC-11;
- acidification of land and water sources, in moles H+ or kg SO2;
- eutrophication, in kg nitrogen or kg phosphate;
- formation of tropospheric ozone, in kg NOx, k O3 eq, or kg ethene; and
- depletion of nonrenewable energy resources, in MJ.
Compliance evidence requirements:
- A short summary report presenting LCA results for reference case and design case for each environmental indicator listed above and each life cycle stage A-C
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.
