On-going Benefits of BAS for Green Buildings
• Building Automation Systems can help maintain LEED intent through a building’s life cycle– Weather-factored energy usage data and graphs
pinpoint building performance difference over time– Recommissioning capabilities– Remote diagnostics, etc.
• BAS will help set the stage for LEED-EB Certification– Trending and reporting capabilities to tie into
maintenance and operation of a building
