BREEAM HIGHER EDUCATION AND LABORATORIES Peter James Higher Education Environmental Performance Improvement (HEEPI)
BREEAM CHANGES BREEAM 2008 general changes - Credit updating, e.g. Energy & EPCs - Revised weightings - Minimum requirements - Innovation and exemplary credits - Post Construction Review BREEAM HE campus changes BREEAM HE lab related changes
NEW/MODIFIED CREDITS HEALTH17 - Use of BS CEN on fume cupboard safety - Explicit H&S sign off MANAGEMENT1 – Commissioning MANAGEMENT4 – Building User Guide + 2cnd credit for Laboratory User MANAGEMENT – Early stage design process
Choice from a ‘menu’ - up to 5 for larger labs, 3 for medium Based on expert consultation process Fume cupboard credits (1.5) - First credit mandatory for labs with fume cupboards 10 additional half credits LAB ENERGY CREDITS
General laboratory supply air AHUs with heating and cooling General laboratory extract systems Laboratory local extract (ducted) – 1.0 Containment area (no HEPA) Containment area (HEPA) – 2.5 Fume cupboard extract – 1.5 FAN POWER (Watts/Litre/Second )
BREEAM HIGHER EDUCATION SHARING EXPERIENCE -User group -User evaluation EFFECTIVE IMPLEMENTATION -Post occupancy evaluation -BREEAM in Use BUILDING CAPACITY -HE specific training -Sector assessors -Referral service? DRIVING IMPROVEMENT -Innovation credits -Benchmarking -Linking with DECS CONTINUOUS IMPROVEMENT
Grouping/isolation of high filtration/ventilation activities Low pressure drop design - optimised duct runs; use of 3D modelling Specification and achievement of best practice fan power VENTILATION CREDITS
Heat recovery - e.g. exhaust air (where no risk of cross- contamination) Cooling recovery Grouping of cooling loads Specification of free cooling coils HEAT AND COOLING CREDITS
Design integration - a documented process of dialogue and challenge between key suppliers (especially architects and engineers) and users to achieve right sizing; eliminate unecessary contingencies etc. Load responsiveness - modularity; variable speed drives and pumps etc. SYSTEM INTEGRATION CREDITS
Credit 1 – Exhaust volume air flow of below 0.16m 3 /second Credit 2 – Below 0.12m 3 /s Achieved – GSK; Newcastle Comparison – Traditional CAV 0.25m 3 /s Comparison – Cambridge 0.175m 3 /s Prerequisite – HEALTH17 (BS 14175) + design team assurance on safety FUME CUPBOARD CREDITS
Defining laboratories Avoiding perverse incentives - fume cupboards and air change rates Precise credit definitions - design integration - laboratory user guide - low pressure drop design KEY QUESTIONS
