Context

This low-energy renovation project will be realized in stages. The programme and building arrangement will not be modified.

Interventions

  • Insulation of roofs
  • Insulation of rear and side exterior facade with plaster finishing
  • Replacement of single glazing by double glazing
  • Energy efficient appliances and lighting
  • Wall injections against rising humidity
  • Planned works: insulation front facade, solar panels

Insulation

In the first stage the roof was insulated and altered in view of the insulation of the front facade in a later stage. The rear and side facade were insulated and plastered.

Ventilation

Because of the favourable interior climate, the installation of balance ventilation was not taken into consideration.

Heating

No changes were made during the renovation.

Sanitary hot water

A geyser (gas water heater) was installed. The ‘wet’ rooms were positioned on top of each other to reduce water piping length.

Electricity

The owners intend to provide a 22m² solar panel installation.
