How can a public building be made more energy efficient (air conditioning, heat pumps, LEDs?)
A significant proportion of the energy consumption in every public building is generated by the interior and exterior lighting systems, and above all by heating and/or cooling systems.
In this context a number of measures of varying complexity can be taken in order to improve the building’s energy efficiency:
- Replacing traditional lights with more efficient units that use 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 heat sources such as geothermal units. These can provide an innovative, sustainable solution that will achieve a significant reduction in electricity use, as well as providing greater comfort and improved performance. They also simplify the energy management of a building.
- Installation of heat pump systems coupled with solar panels: these ensure maximum savings by using energy generated by the panels during the middle of the day to power the heat pump, which experiences its peak use during that same period.
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 that will facilitate the building’s occupation and use.
