Seeking guidance for including demolition of a building in A5 for the new building. Supposedly ASHRAE 240p has guidance on this, but I missed the review and it is not posted yet. Thank you! ---

Hey Lindsey! Below are the snippets here from ASHRAE 240P (draft!) and RICSv2. If you want a copy of the 240P draft, happy to send it along. You can email me at [j.rusk@ehdd.com](mailto:j.rusk@ehdd.com). **RICS** > Pre-construction demolition (A5.1) Deconstruction/demolition of the existing built asset is essentially the same as the module C end-oflife impact of the existing built asset. However, to inform decision-making when comparing designs for retrofit or new-build options during the concept design phase, the deconstruction/demolition impact should be reported under A5.1 as part of the upfront carbon impact. > > For retrofit schemes, any deconstruction/demolition as part of the main works should be accounted for in A5.1. > > To calculate the carbon emissions associated with pre-construction demolition, actual figures should be used where possible, including transport to waste processing, and waste processing and disposal impacts themselves. If actual figures are not available, a standard assumption of 50kgCO2e/m2 should be adopted, applied to the GIA of the existing areas being demolished that fall within the boundary line. The kgCO2e/m2 value suggested should be superseded with site-specific data when available. The loads and benefits of recovery of any pre-demolition waste should be considered in module D1. **ASHRAE 240P** > 6.5.3.1 Pre-construction Demolition (A5-1) > This stage shall include GHG emissions due to any demolition or deconstruction of existing structures required for the project prior to starting construction, including GHG emissions from disposal of materials. > > 6.5.3.1.1. As-Designed Compliance Path. > GHG emissions shall be estimated based on 35 kg CO2e/m2 of the gross floor area of the building being demolished. > > 6.5.3.1.2 As-Built Compliance Path > Follow procedure according to Section 6.5.3.2.2 (As-Built Compliance Path for A5-2) for GHG emissions arising from demolition activities on site and Section 6.5.3.3.2 (As-Built Compliance Path for A5-3) for GHG emissions arising from demolition waste.
