4. RENOVATION / RENOVACTIVE BACKGROUND
Statistics show that around 80 million Europeans live in
damp and unhealthy buildings. We humans need daylight
and fresh air when we are indoor as these elements have
a positive effect on our health and well-being as well as
our ability to learn.
Living in a good, mould-free indoor climate reduces the
risk of developing asthma by 50%. State-of-the-art
construction technology should focus on reducing heating
demand through highly efficient products and airtight
construction, but without compromising the health of the
people living inside the buildings.
Energy-efficient and healthy buildings should go hand in
hand.
5
In 2050
9 out of 10 of the existing
buildings in Europe
will still be in use
1/2
Cut the risk of
developing asthma in half
by avoiding mould
We spend up to 90% of our
time inside buildings –
living,working, learning
and playing
5. RENOVACTIVE / VISION
VELUX RenovActive provides an affordable and replicable solution to renovate buildings
that live up to the Active House vision of sustainable buildings with a main focus on the
indoor comfort of the people living in it thanks to daylight and ventilation.

6. RENOVACTIVE / MAKING SUSTAINABLE RENOVATION AFFORDABLE
The prototype
A climate renovation of a three façade
house from the 1920s.
The house was uninhabitable due to its
poor condition.
The house belongs to a social housing
company Foyer Anderlechtois which owns
3,600 dwellings, including half of the 330
houses in the garden city where
RenovActive is located.

9. RENOVACTIVE / REPLICATION ELEMENT
Light and air shaft
Central open staircase with VELUX INTEGRA windows
above.
Allows chimney effect for ventilation and brings daylight in
the house.

10. RENOVACTIVE / REPLICATION ELEMENT
Level and quality of daylight
Importance of balanced distribution of daylight throughout
the house.
Renovations made in RenovActive prototype
Enlarged windows, front and back facade
Windows in extension
Windows in side facade
Four roof windows (two in the attic bedroom, two above
the staircase)
Flat roof window in extension
Sun tunnel in bathroom

11. RENOVACTIVE / REPLICATION ELEMENT
Hybrid ventilation system
A demand-controlled (temperature, humidity, CO2, odour)
mechanical extraction ventilation (MEV – System C+) in
combination with demand-controlled natural ventilation
(NV)
When Toutdoor<14°C, air is taken in through window grills and
extracted by the C+ unit (mechanical extract)
When Toutdoor>14°C, air is taken into the house through
automatically opened façade and roof windows and also
extracted through windows

12. RENOVACTIVE / REPLICATION ELEMENT
Sun shading
Control of indoor climate by automated external sun
shading

14. OCCUPATION AND POST-OCCUPANCY EVALUATION
After completion of the renovation works (foreseen in the end of
2015), the house will be open for visits during 1 year, and then
handed over to a Foyer Anderlechtois beneficiary
During the first 2 years of occupation, the performance of the house
will be monitored
Technically by measuring indoor climate parameters and energy performance
The technical monitoring will be made with a room-based system, e.g. NetAtmo
Psycho-social techniques including questionnaires and interviews, based on a method developed by
Humbolds University of Berlin
