1. Passive house Project
Myself and five other peers from different disciplinary backgrounds were selected to
attend a Passive House retrofit project in Denmark. Upon arrival we were briefed with
the task that follows. Working with other nationalities such as: Portuguese, Hungarian,
Estonian, French, Lithuanian and Danish from all specialist backgrounds. Once
divided into 12 groups of 5 we were set to achieve a common goal of retrofitting a
typical traditional Danish residential complex to meet passive house standards.

VENTILLATION SYSTEM
Fresh air without dust, and pollen
Decrease thermal losses
Don’t have to install too high-capacity
heating-cooling system
INTERIOR DESIGN
Make low changes
Some modification in the bathrooms and in
the kitchen.
SERVICE
Each staircase has a riser connected to four
flats.
In the basement we have to move the
bathroom to have easy connection to the
risers.
