Lancaster Institute of Contemporary Arts (LICA) • 4900 m 2 gross floor area over three floors • top floor (1900 m 2) is currently shell space • basic building cost : £ 1, 178/m 2

Lessons Learnt § Tendered in June 2009 Under budget therefore. . Example image The University had a couple of aspirations: § BREEAM Bespoke Excellent -> BREEAM HE Outstanding § 2 storey to 3 storey § MS appointed in August 2009 Example image

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 Displacement ventilation, recovery (75% efficient 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 m 3/(h. m 2) • EPC of 21 • Heat recovery • Enhanced U-Values • Renewable technology • Water management • District heating with CHP • Photovoltaic cells (150 m 2)

Energy Use Predicted electricity consumption – 73. 4 k. Wh/m 2 Predicted fossil fuel consumption - 148 k. Wh/m 2 Predicated renewable energy generation – 3. 46 k. Wh/m 2 TOTAL CONSUMPTION – 217. 97 k. Wh/m 2 per annum

Water Use Predicted Water Use – 2 m 3 / 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

BREEAM Assessment • • 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 &
