Idea of the subcredit:

Conduct as high-quality LCA as possible. The quality of your LCA is evaluated based on the LCA tool quality as well as materials assessment scope. The quality is assured with the Mat 01 calculator: 70% of the quality is defined by the tool used and 30% based on how many material classes are included in the assessment. 75% performance is required for 2 credits and 85% for achieving the additional exemplary credit on top.

One Click LCA is the highest rated LCA software for Mat 01 verified by BRE and will deliver 70 / 70 % of tool quality. This means you already have 80 % achieved just by choosing the tool and filling in mandatory material categories. The maximum potential with One Click LCA is 100% which enables you to get the 2 credits right away and go for the exemplary credit more easily than ever.

 

Idea of the subcredit:

The parts of this credit involving a life-cycle perspective both apply the ISO 15686:5 standard and require demonstrating by examples that LCC plans have been used to influence building and systems design and specification to optimize life cycle costs. Tools for these analyses are included in One Click LCA.

• Two credits are awarded for performing an entire asset elemental LCC plan at the Concept Design Stage with design option appraisals in line with for the service life set by the client brief.
• One credit is awarded for component level LCC options appraisal developed by the end of Technical Design Stage that consider envelope, services, finishes and external spaces, where present.

Subject to achievement of the first credit, the project team may use LCA to demonstrate the carbon impact of it’s chosen LZC system(s), accounting for its embodied carbon emissions and operational carbon savings and emissions. The LCA study must be completed in accordance with ISO 14044:2006 standard and consider a 60 year period with any necessary replacements and maintenance occurring during that period. This delivers one additional credit. Although the feasibility study does not require it, the software may also be used for life-cycle cost analyses between the different LZC options available. Tool for performing this analysis is included in One Click LCA platform.

While these are not life-cycle metrics, One Click LCA platform can also support the data collection requirement of the Man 03, section Monitoring of construction site impacts (2 credits) as well as the Man 05 Afercare exemplary credit by collecting data from the construction site or enabling following the in-life performance of a building for three years after its completion. The software also allows specifying and tracking the use of EPDs in projects, which can support two more credits.
