BREEAM Refurbishment & Fit Out
• Launched 2014
• First BREEAM scheme specifically for refurb / fit out
• Other schemes – New Construction, Domestic refurbishment, Home Quality Mark
• Simple buildings & shell only / shell and core can be assessed

Scope of BREEAM & Ska
• BREEAM is assessed in 4 ‘Parts’:
• Fabric & Structure • Core Services • Local Services • Interior Design
• Ska includes all measures relevant to a project – i.e. what is in scope

Assessment
§ Pre-assessment - Enables development of a strategy"- Required for planning"
§ Design Stage: Proof of intent - Drawings"- Specifications"- Reports"- Documentation"
§ Post Construction Stage: Proof of implementation - Purchase Orders etc"- Certificates"- Site Visit"

• 131 GPMs in Ska
• 51 Credit areas in BREEAM
• BREEAM tends to have more overarching criteria
