Finding #1Energy Strategy and BREEAM Assessment Difficult to Understand BWH Design Plan

Recommendation:Locate or obtain a post-construction BREEAM AccreditationDiscrepancies in energy and carbon emission values from Energy Strategy **BWHs post-construction BREEAMImprovements to obtain higher ratingHealth and wellbeing, energy, transport, water, land use and ecology, pollution5Trend Sensors are Improperly CalibratedFinding #2Building Energy AnalyticsTrend Control Points are Unintuitively NamedData TypeAccuracyLighting76.1%Small Power67.5%Pumps & Cooling81.4%

Finding #3Energy Building PerformanceElectricity Use is 42.3 % Higher than Predicted

Recommendations:Regulate Small Power Devices at BWH

Restrict After-Hours Work to One FloorSmall Power is 29% Higher than PredictedLighting Usage is 4.2 % Less than PredictedPV Panels are withing 15% of Predicted ValuesBilled electricity dataElectricity use is 42.3% higher than predictedSmall Power 31% higher than predictedLighting and PV solar panels performance7

Finding #4Energy Management Companies8 Companies Available for Energy Management

Options:Scenario 1: Keep TEAM Sigma

Scenario 2: TEAM Bureau Services

Scenario 3: Switch Providers Entirely
