Energy efficiency

The overall goal of energy efficiency in buildings is to use energy more efficiently and reduce the actual energy consumption.

Energy efficiency targets for buildings are set by European Union directives.
According to the goals of the new directives, the energy efficiency class of residential buildings should be at least E by 2030 and at least D by 2033 (on the A-G scale, the last category of the scale includes the 15% of the least energy efficient buildings in member-states). Non-residential and public buildings should reach this level by 2027 and 2030 respectively.

Improving the energy efficiency of buildings also includes reducing greenhouse gas emissions, energy and building maintenance costs, making buildings compliant with internal climate requirements, and introducing renewable energy sources.

Our experts take an integrated approach, so energy efficiency ensures not only energy savings, but also the durability of buildings and a good indoor microclimate.


  • Lower energy costs: an energy-efficient building requires less heating, cooling, lighting, and electricity, so you can expect lower costs.
  • Improved indoor climate: an energy-efficient building provides the optimal temperature, humidity, ventilation, and lighting, which promotes occupant well-being, health, and productivity.
  • Reduced environmental impact: an energy-efficient building helps mitigate climate change and ensures a more sustainable society.
  • Increased value of buildings: energy efficiency increases the value of buildings, making them more attractive to investors and tenants.
