In order to cope with the energy, financial, political, societal and environmental crises, all healthcare districts in Europe are urgently seeking to substantially reduce their energy consumption and carbon emissions. In this context, they are planning to design new energy-efficient building projects, as well as energy-efficient retrofitting of existing buildings. The processes of design, construction, operation and maintenance are the key activities that underpin the success of the ambitious objective of reducing energy. To support a successful direction of the processes, there should be indicative performance criteria to which management decisions can be weighed against. This deliverable focusses on how this is done for decisions taken during the design process of a hospital building.
Three sets of key performance indicators (KPIs) were defined. The most important KPI set within STREAMER is that of Energy Performance. However, in order to ensure high quality performance of a healthcare estate – and because energy saving and quality always have major impacts on the budget of a hospital – the Financial and Quality performances are also addressed.
These three KPIs were operationalized in seven performance indicators (PI) that are sensitive to building-oriented, as well as process-oriented factors, stressing the fact that for example energy use is not only dependent on building and installation factors (building-oriented) but also on process factors (process-oriented), meaning the utility of the building. Calculation methods (how to calculate the performance of these indicators based on information available during the (early) design), were developed and tested at expert level.
The resulting calculation measurements were validated (through a feasibility test) in two case studies: Rijnstate Hospital in the Netherlands and Careggi Hospital in Italy. The validated set of KPIs and calculation methods will be further used for integration into the decision-support tool developed in D3.6. This tool should be able to calculate and visualize the performance of different design scenario’s supporting management to take a weighted decision based on the energy, financial and quality performance of the design.
