How can a public building be made more energy efficient?

A significant portion of the energy every public building consumes is generated by its interior and exterior lighting systems, and above all by its heating and cooling systems.  

 

A number of measures of varying complexity can be taken in order to improve a building’s energy efficiency:

 

  • Replacing traditional lights with more efficient units that use LED technology, saving up to 80% on energy;

 

  • Replacing heating and cooling equipment with electric heat pumps, or with renewable heat sources such as geothermal units. These innovative and sustainable systems significantly reduce the amount of electricity needed, provide greater comfort, improve performance, and simplify building energy management;

 

  • Installing heat pump systems coupled with solar panels: these systems ensure maximum savings by using energy generated by the panels during the day to power the heat pump, which experiences its peak use during that same period.

 

Another option is to implement an integrated energy system or Building Management System (BMS), which has both hardware and software components. These systems monitor and control energy consumption, generate data for analysis, and allow for automated control and management of energy generating plants.

 

A BMS can be a key tool for energy managers because it can optimize consumption while ensuring comfort levels that will facilitate the building’s occupation and use.
