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 14175 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
LAB ENERGY CREDITS • 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
FAN POWER (Watts/Litre/Second) • General laboratory supply air AHUs with heating and cooling - 1.5 • General laboratory extract systems - 1.2 • Laboratory local extract (ducted) – 1.0 • Containment area (no HEPA) - 1.5 • Containment area (HEPA) – 2.5 • Fume cupboard extract – 1.5
CONTINUOUS IMPROVEMENT SHARING EXPERIENCE -User group -User evaluation BUILDING CAPACITY -HE specific training -Sector assessors -Referral service? DRIVING IMPROVEMENT -Innovation credits -Benchmarking-Linking with DECS BREEAM HIGHER EDUCATION EFFECTIVE IMPLEMENTATION -Post occupancy evaluation -BREEAM in Use
VENTILATION CREDITS • 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
HEAT AND COOLING CREDITS • Heat recovery- e.g. exhaust air (where no risk of cross-contamination) • Cooling recovery • Grouping of cooling loads • Specification of free cooling coils
SYSTEM INTEGRATION 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.
FUME CUPBOARD CREDITS • Credit 1 – Exhaust volume air flow of below 0.16m3/second • Credit 2 – Below 0.12m3/s • Achieved – GSK; Newcastle • Comparison – Traditional CAV 0.25m3/s • Comparison – Cambridge 0.175m3/s • Prerequisite – HEALTH17 (BS 14175) + design team assurance on safety
KEY QUESTIONS • Defining laboratories • Avoiding perverse incentives- fume cupboards and air change rates • Precise credit definitions- design integration- laboratory user guide- low pressure drop design
