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
Lessons Learnt 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 Example image Example image
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 Timber Cross Laminated Construction
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)
Energy Use 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
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
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 & Post Construction
