The BREEAM Design can be Improved Finding #1 Energy Strategy and BREEAM Assessment Difficult to Understand BWH Design Plan Recommendation:  Locate or obtain a post-construction BREEAM Accreditation

Trend Sensors are Improperly Calibrated Finding #2 Building Energy Analytics Trend Control Points are Unintuitively Named Data TypeAccuracy Lighting76.1% Small Power67.5% Pumps & Cooling 81.4% “Town Hall 16A” “Chiller Shunt 05A” Recommendations:  Rename Trend sensors and aggregate them appropriately  Recalibrate Trend sensors

Finding #3 Energy Building Performance Electricity Use is 42.3 % Higher than Predicted Recommendations:  Regulate Small Power Devices at BWH  Restrict After-Hours Work to One Floor Small Power is 29% Higher than Predicted Lighting Usage is 4.2 % Less than PredictedPV Panels are withing 15% of Predicted Values

Finding #4 Energy Management Companies 8 Companies Available for Energy Management Options:  Scenario 1: Keep TEAM Sigma  Scenario 2: TEAM Bureau Services  Scenario 3: Switch Providers Entirely 8 Boroughs Use Similar Energy Management

34% Know of BWH BREEAM Accreditation Finding #5 Occupant Satisfaction/Awareness 79% Believe BWH is a Better Environment Recommendations:  Increase recycling participation in BWH  Increase occupant awareness of BWH features with visual tools

Finding #6 Visual Tools Energy Management Offers Energy DashboardsSankey Diagrams are Effective Visual Tools Data for Complete Sankey Data is not Available Recommendations:  Online dashboards of utility information should be published  Continuous production of Sankey Diagrams  Display visuals in elevator floor lobbies
