Compact construction: optimise your living space

Compact construction is not just about building on a small area. Nowadays, this principle is also related to the energy efficiency of a home. That means it’s not about the total area of the building project, but about the ratio between the protected volume and the loss area of the house. These two parameters play a key role in EPC legislation and help determine the energy score of a house.

What does compact construction mean?

Compact construction does not only mean surface area, but also energy efficiency. Architects are increasingly looking for the ideal ratio between the protected volume of a house and the loss area. The protected volume is the sum of all areas that are protected against heat loss to the outside environment via thermal insulation. The loss area is the sum of all surfaces that are in contact with the outside environment through interruptions in the building envelope. 

In order to optimise all the available space, the so-called loss areas are increasingly being used. For example, homeowners are choosing to have a ‘man cave’ in the basement or a cosy studio in the garage. These areas also need to have additional insulation

How can you expand the living space the smart way?

It’s not only the basement or garage that offer opportunities to create more living space, the roof also has various options! Have you ever considered a roof terrace or green roof, for example? A green roof offers various other advantages apart from extra space:

  • A green roof acts as a water buffer and provides a solution to overloaded drains.
  • A green roof extends the life of the roof covering thanks to the UV-filtering effect of the vegetation.
  • A green roof provides acoustic insulation.
  • Thanks to a well-fitted green roof, the house’s primary energy consumption will drop significantly.
