Passive House Project

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.

PROPOSAL

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.

SOLAR

SOLAR HEATING: THE SUN IS TOO LOW IN DENMARK WEATHER OFTEN CLOUDY

PHOTOVOLTAICS PV PANELS TO SUPPORT THE ELECTRICITY SUPPLY SYSTEM: Quick Step Solar PV

SOLAR

SYSTEM: QUICK STEP SOLAR Dimensions: 2000 mm x 365 mm Weight: 19.10 kg Module area: 0.73 m2 Module output: 68 Wp Âą 10 % Operating voltage: VMPP= ca. 14.20V Operating current: IMPP= ca. 4.80 A Open circuit voltage: VOC= 17.10 V Short circuit current: ISC= 5.12 A Connection: MC- box, 600 mm wire included

GROUND SOURCE

HORIZONTAL SURFACE COLLECTOR ENOUGH SPACE TO INSTALL CAN BE USED FOR HEATING AND COOLING TOO DOESN’T DEPEND ON WEATHER COEFFICIENT OF PERFORMANCE IS GOOD

HEATING

CLOSED LOOP VERTICAL GROUND SOURCE HEATING SYSTEM ENERGY INPUT IS REDUCED AND LARGER RADIATORS USED TO INCREASE EFFICENCY WITHOUT REDUCING PERFORMANCE

BIOMASS

HIGH EFFICENCY CARBON NEUTRAL SYSTEM (IN OPERATION)

USED ONLY TO SUPPLEMENT HEAT PUMPS FOR DOMESTIC WATER

MV

kitchen ventilation x bathroom ventilation x W/C+ minimum fresh air = overall air flow rate

Overall air flow for the building

60 x 40 x 20 + 960= 1440 m3/h Minimum fresh air flow rate per person

30 x 4 x 8 = 960 m3/h

BUILDING

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

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.

BY CHANGING THE SHAPE OF THE ROOF WE HAVE ENOUGH SPACE TO CREATE A GREEN TERRACE

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

5. Optigreen protective and water-holding geotextĂ­tia 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.
