A screening life cycle analysis of a hospital building in Flanders Milena Stevanovic Doctoral researcher @KU Leuven Project architect @VK STUDIO Architects, Planners & Designers 1

Summary Introduction Objective Methods Results Conclusions

Objectives gain better insights into the environmental impacts and financial costs of hospital buildings reveal the major obstacles for a quantitative approach when assessing the hospital building sustainability identify the hotspots from both an environmental and economic point of view

State-of-the-art – Building sustainability assessment tools Certification schemes – qualitative tools Life cycle assessment tools – quantitative tools qualitative tools quantitative tools (MMG)

The strength of the research project Integrated life cycle assessment (LCA) and life cycle costing (LCC) approach Based on an existing LCA and LCC-based method of the KU Leuven LCA LCC Economic sustainability = LCC Environmental sustainability = LCA Social sustainability = sLCA

Methodology Life cycle assessment (LCA) - MMG method + KU Leuven - Excel-based tool Life cycle costing (LCC) - Excel-based tool developed at the Architectural Engineering division (KUL)

Methodology Life cycle assessment (LCA) - MMG method + KU Leuven - Excel-based tool Life cycle costing (LCC) - Excel-based tool developed at the Architectural Engineering division (KUL)

AZ Sint-Maarten (Mechelen) - case study data availability one of the most recent company’s projects in Flanders (still under construction)

Results Environmental costs of the general hospital Sint-Maarten - life cycle phases

Results Financial costs of the general hospital Sint-Maarten – life cycle phases

Results Total cost – life cycle phases (environmental + financial costs)

Results Impact indicators - CEN

Results Impact indicators – CEN+

Conclusions and further research methodology of the research division ‘Architectural Engineering’ needs adaptations to ensure applicability on hospital buildings Identification of the three major hotspots: a) electricity use for hospital appliances (HVAC and medical apparatus) and lighting b) spatial heating and c) material production processes

Conclusions and further research elaborate an extensive database with predefined technical solutions for each of the building elements include the HVAC installations transport from and to the hospital (patients, staff, logistics)
