LIVING BUILDING CHALLENGE
The LIVING BUILDING CHALLENGE (LBC) is an aspirational sustainable building standard program that was created in 2006 by the INTERNATIONAL LIVIING FUTURE INSTITUE based in Seattle in the US. The standard is appropriately called a ‘Challenge’ as the bar for meeting the standard is high compared with other standards. Typical best practices for green and high performance buildings must be exceeded to deliver positive environmental impacts rather than just limiting negative impacts. To be certified, projects must meet a number of ambitious performance criteria including; net zero energy, waste, and water, and since the standard is based on actual, rather than modelled or anticipated, performance projects must be operational for at least twelve consecutive months prior to audit to verify compliance. There are seven performance areas including: site, water, energy, health, materials, equity, and beauty. Adoption of the standard has been mostly in the US and Canada, but in 2013 a UK LIVING BUILDING CHALLENGE COLLABORATIVE was created to increase awareness of the Challenge in the UK.
