A significant part of the energy consumption in every public building is generated by indoor and outdoor lighting systems, and above all by heating and/or cooling systems.
In this context, a number of measures of different complexity can be taken in order to improve the building’s energy efficiency:
- Replacing traditional lights with more efficient units like LED technology, for example. This yields savings of 80% regarding the energy used for lighting.
- Replacing heating/cooling equipment with sustainable technology like electric heat pumps or renewable sources (such as geothermal units). These can provide an innovative, sustainable solution that will achieve a significant reduction of energy use, and guarantee greater comfort, improved performance and the simplification of the building’s energy management.
- Installation of heat pump systems coupled with solar panels: these ensure maximum savings by using energy generated by panels during the middle of the day to power the heat pump, which experiences its peak use during that same time.
- Implementation of an integrated energy system in the building (BMS, Building Management System). This is a key instrument for the energy manager of the building (or buildings) and is capable of optimising energy consumption, creating comfort levels in favour of the building’s occupation and use.
