• Masterplan Refresh• Projects completed • On site projects• Future works
• Lancaster University BREEAM experience• Case Study – Lancaster Institute of
Contemporary Arts (LICA) Outstanding• BREEAM assessment
Lancaster Institute of Contemporary Arts (LICA)
• 4900m2 gross floor area over three floors
• top floor (1900m2) is currently shell space
• basic building cost : £1,178/m2
Tendered in June 2009
Under budget therefore ....
The University had a couple of aspirations: BREEAM Bespoke Excellent -> BREEAM HE
Outstanding 2 storey to 3 storey MS appointed in August 2009
Lessons Learnt

Timber Cross Laminated Construction
• All floors, walls, roof, stairs, columns and beams made from cross-lam or glu-lam timber
• Raw material – from sustainably managed forests• Factory based component pre-fabrication
Ventilation Strategy – Double height space
Extract picking up heat from lighting rigs for heat recovery (75% efficient)up heat from lighting rigs for heat recovery (75% efficient
Underfloor heating in sprung floor
from lighting rigs for heat recovery (75% efficient
Displacement ventilation, variable flow linked to occupancy
Electrical Design
Constraints on distribution and servicing (no GF floor void, partial ceiling void)
Minimising the ‘clutter’
Significant interfacing with specialists
BREEAM compliant lighting and controls
Energy Use
Drive towards aiming for Outstanding came from the advantages of timber construction
Some of the principle points:
• Air tightness 3.02 m3/(h.m2)
• EPC of 21
• Heat recovery
• Enhanced U-Values
• Renewable technology
• Water management
• District heating with CHP
• Photovoltaic cells (150m2)
Predicted electricity consumption
– 73.4kWh/m2
Predicted fossil fuel consumption
- 148kWh/m2
Predicated renewable energy
generation
– 3.46kWh/m2
TOTAL CONSUMPTION
– 217.97 kWh/m2 per annum
Energy Use
Water Use
Predicted Water Use – 2m3 / person / annum
50% Water use to be provided by rainwater using the rainwater harvested from the roof
Remaining rainwater is discharged into the pond which provides attenuation
• Design for BREEAM compliance• - Building Form• - Timber Frame• Interaction between credits• - Materials & Waste• - Energy & Pollution• - Free cooling & mechanical cooling
• Time-limited credits during:• - design stage• - construction stage• Inconsistencies of BREEAM criteria
BREEAM Assessment
• Management of BREEAM process
• Design and construction teams interaction
• In depth knowledge of BREEAM manual & assessment calculations
• Potential credits evaluation at all stages of assessment
• Safety margin
• Assessment involvement to achieve target
• Progression between Design Stage & Post Construction
BREEAM Assessment
