Cost-effective energy savings in healthcare
HosPilot is a project focused on Information and Communication Technologies (ICT) for energy efficiency in hospitals. It is co-funded by the European Commission under the ICT Policy Support Programme and involves 11 partners in five European countries. It includes a decision support software tool for hospital managers which has been designed to provide the best ICT advice for new-builds and when refurbishing hospitals.
In the complex environment of a hospital, heating, ventilation, air-conditioning (HVAC) and lighting account for nearly 80% of all energy use. The potential savings achievable with investments that have a payback time of less than seven years can reach up 40%, depending on the current condition of the hospital, where HVAC and lighting are the major contributors. More than half of these savings can be attributed to the impact of ICT, through the use of presence detection equipment, for example. The HosPilot project aims to support
decision makers by offering an integrated approach designed to help drastically reduce the energy consumption of newly built hospitals and existing hospitals being refurbished, while at the same time increasing well being and comfort for the people in the building. The HosPilot service can provide valuable
help for hospital managers – combining expertise on HVAC, lighting, and ICT. The HosPilot software tool makes it possible for

Henk Schepers holds a PhD in Computer Science from the Eindhoven University of Technology and an MBA from Tias Business School. He has held various positions in product and technology development, project management and business development. Currently he is heading the systems & solutions predevelopment activities at Philips Lighting, where he and his team are maximising the energy efficiency for the different indoor and outdoor use cases. Using the potential of new lighting, sensor and ICT technology, and through integration with existing and emerging systems and infrastructure, they optimise the balance between safety, comfort, well-being, productivity and the energy consumption.
technical staff in the hospital to simulate different refurbishment scenarios, instantly visualise their estimated impact, and therefore decide the best way and place to invest money. To obtain the same result without using
the HosPilot service, a decision maker would need to separately consult an expert for lighting, an expert for HVAC, and then to analyse and compare the offers. This often reveals itself to be a difficult and time- consuming exercise. Three main phases can be identified in
the HosPilot methodology: Phase 1: Collecting and processing
useful information about the hospital – The more details that are provided to the tool, the better the estimation will be. Parameters that can influence the climate and brightness of a room, for example, include: • Hospital building location (longitude, country, city, etc).
• Building data (orientation, outer envelope, structure, etc).
• Room level data (room geometry, windows, walls, room size, etc).
• Existing systems concerning HVAC and lighting.
The decision makers firstly have to fill in general hospital data. Then they choose the
rooms that they want to refurbish. The next questions will be based on local regulations and local default values, helping the decision makers to fill in room
data and room requirements easily. Phase 2: Proposing possible solutions
to exploit the opportunity – According to the hospital needs, the HosPilot engine will propose appropriate solutions by analysing existing systems. It also takes into account default room requirements, based on European and National norms and standards applicable for lighting and HVAC. The decision maker is able to change these parameters, but if the user chooses a parameter that is outside the norms, they will be given a suitable warning. The HosPilot engine will give applicable solutions for the selected rooms, and the energy demand for them is
calculated. Phase 3: Calculate estimations of
energy savings, total costs and give feasibility indications according to the solutions chosen – To make these appraisals, the hospital’s baseline energy demand is calculated. These calculations are based on: • Reference energy demand calculation (without any energy conservation
