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% efficientDisplacement 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

BREEAM Assessment

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
