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.

BUILDING

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.

GREY WATER RECYCLING

Collect rain for watering our green roof

Enough space for the water tank under

the roof.

WATER STORAGE GREY

WATER

Collect water from the

sink, and from the

shower for the toillet.

ROOF

BY CHANGING THE SHAPE OF THE ROOF

WE HAVE ENOUGH SPACE TO CREATE A

GREEN TERRACE

1. Optigreen seed mixture type E Good seed mix composition and various coordinated breeds of plantation.

2. Extensive substrate type E * (5-20 cm)

Multi-layer extensive green roof design coordinated substrate

with high water storage capacity.

3. Filter mat type 105 Water flow near a high ability

to prevent the leaching of

fine soil particles.

4. Optigreen drainage system FKD 40 (4 cm) Quickly drain excess water preventing water swelling Balancing filter diffusier

5. Optigreen protective and water-holding geotextítia It protects the root or a film. the roof membrane from damage and keeps the water. A filter

removes soil from the water to prevent gutter blockage.
