"The additional cost of the specific green features (e.g. solutions to reduce the energy consumption and the installations utilising energy from renewable sources) is comparable to the accumulated cost of a conventional building over a certain period of time, considering the foreseeable energy cost increase. This period of time can vary a lot depending on factors such as the availability and amount of subsidies," the authors note.
Recomendations are, for example:
- Use heat recovery systems
- Use efficient installations according to the energy demand
- Reduce the heat loss by minimising length of piping
- Use efficient installations according to the hot water demand
- er c.
"The way the building operates plays an important role in keeping cost down. The awareness and cooperation of staff and even patients in saving energy, water and reducing waste can have an important impact. For example, energy can be wasted by simply forgetting to switch lights off despite an efficient and energy saving lighting system with plenty of windows to guarantee daylight ..."
