# Life Cycle Assessment - Resources
A quick Google of 'Life Cycle Assessment' renders over 450,000,000 results. To make life easier, here is a list of some of the most transparent methods, standards and research on Life Cycle Assessment for buildings.
* [RICS - Whole life carbon assessment for the built environment 1st edition (2017)](https://www.rics.org/globalassets/rics-website/media/news/whole-life-carbon-assessment-for-the--built-environment-november-2017.pdf) - RICS produces a range of professional standards, guidance and information documents. This guide provides requirements for conducting whole-life carbon assessments for construction projects in line with EN 15978. It also focuses on the interpretation and practical implementation of the EN 15978 methodology.
* [LETI - Embodied Carbon Primer (2020)](https://www.leti.uk/_files/ugd/252d09_8ceffcbcafdb43cf8a19ab9af5073b92.pdf) - This Embodied Carbon Primer offers supplementary guidance to those interested in exploring embodied carbon in more detail to support the need for knowledge in the built environment industry surrounding embodied carbon reduction strategies and calculations.
* [CIBSE TM65 (2021)](https://www.cibse.org/knowledge-research/knowledge-portal/embodied-carbon-in-building-services-a-calculation-methodology-tm65) - Embodied carbon in building services: a calculation methodology. Guides on how to use environmental product declarations (EPDs) for MEP products and methods to estimate the embodied carbon of MEP products.
* [CIBSE TM65 ANZ - Embodied carbon in building services: A methodology for ANZ (2022) ](https://www.cibse.org/knowledge-research/knowledge-portal/tm65anz-a-calculation-methodology-for-australia-and-new-zealand-pdf-2022)- Details alternative assumptions to be made when using CIBSE TM65 in Australia and New Zealand.
* [EN 15978 - Sustainability of construction works. Assessment of environmental performance of buildings. Calculation method (2011)](https://knowledge.bsigroup.com/products/sustainability-of-construction-works-assessment-of-environmental-performance-of-buildings-calculation-method/standard) - Specifies Life Cycle Assessment (LCA) calculation method and other quantified environmental information to assess the environmental performance of a building.
* [PN 326 - BRE Global Methodology For The Environmental Assessment Of Buildings Using EN 15978:2011 (2018)](https://www.greenbooklive.com/filelibrary/EN_15804/PN326-BRE-EN-15978-Methodology.pdf) - Describes BRE Global’s methodology for deriving the environmental performance of buildings using LCA and is complementary to (and complies with) EN 15978:2011.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.betterbuilding.io/user-guide/workflows/carbon/carbon-faqs/life-cycle-assessment-resources.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
