LEED v4.1 for Building Design and Construction (BD+C) and Interior Design and Construction (ID+C) opened for beta registration on January 22, 2019. Here’s a rundown of the biggest changes compared with v4.
Integrative Design Process
The IDP credit is unchanged in that teams still need to do a simple-box energy model and early-phase water calculations. However, there are changes under the implementation phase that now require a letter to be drafted by the IDP leader mapping out the IDP process, rather than a prescriptive checklist to fill out for documentation. Also, the credit now has an option for exemplary performance, not available in v4, that includes the evaluation of Site Selection, Social Equity, and Health & Wellbeing to be included in the process.
