Location of the building Delft

Façade Type Predominantly an Active Wall (or Climate Wall).

Ventilation of the cavity Mechanically ventilated cavity. The air flow rate is 75 m³/h per linear meter of façade. An extra skin is applied to the inside of the

build-ing envelope; inside return air is passbuild-ing through the cavity of the façade and returning to the ventilation system. In periods with so-lar radiation the energy, which is absorbed by the blinds, is removed by ventilation. In peri-ods with heating loads, solar energy can be re-covered by means of heat exchangers.

Façade construction – External Double glazing unit with U-value of Pane type 1.5 W/m²K made up of an 8 mm outer sheet and a 6 mm inner sheet with low-E coating – 150 mm depth of the cavity – single pane in-ternal glazing 8 mm thick. It is a tougned glass designed as a sliding door thet gives acces to the cavity for cleaning.

Shading device type Automatically controlled aluminium venetian blinds are placed inside the cavity.

HVAC The active wall is combined with an air-han-dling unit to provide thermal comfort, while the ventilation air is used to control humidity and indoor air quality.

Façade Type Prismatic panel in double envelope system.

Ventilation of the cavity No information given.

Façade construction – The double-skin façade is divided into three Pane type sections. The upper section is made of insu-lating glass with integrated prismatic panels which automatically adjust itself as a function of the altitude of the sun. The vision window is made of clear insulating glass and is manu-ally operated by the occupant during the day-time. The lower level window is automatically controlled to stay closed when solar and ther-mal insulation is required.

Shading device type No information given.

HVAC No information given.

Location of the building Brussels

Façade Type Predominantly an Active Wall (or Climate Wall)

Ventilation of the cavity Mechanical ventilation is required in order to extract the solar heat from the façade cavity.

The air flow rate is 40m³/h per module (width 1.5 m), corresponding to 27 m³/hm. The air velocities are:

Inlet: 0.5 m/s Cavity: 0.05 m/s Outlet: 0.4 m/s

Façade construction – External Double glazing unit with U-Value of Pane type 1.3W/m²K – 143mm depth of the cavity –

clear single internal glazing.

Shading device type Motorized blinds are positioned in the venti-lated cavity.

HVAC Heating: The heating is provided by the sup-ply air, which results in lower installation costs, and means that the glazing can be continued down to the floor level. The ventilation air is re-circulated when the building is not occu-pied.

Cooling: The cooling is provided by mean of chilled ceilings operating with water at tem-peratures between 15°C and 17°C.

Location of the building Luvain (situated in a calm environment) Façade Type There is no horizontal partitioning inside the

façade.

Ventilation of the cavity There is no interaction between the air used to ventilate the building and the ventilation of the façade. The ventilation pattern of the façade is natural and is based on the stack ef-fect. No fan assists the ventilation. When the temperature in the cavity exceeds a given value, motorised windows at the bottom and the top of the façade are opened.

Pane type – Façade Double glazing was placed in both sides of the construction cavity – 70mm depth of the cavity. Solar

con-trols are installed in the cavity.

Shading device type Venetian blinds. In principle the blinds are in all circumstances lowered. They are placed near the interior glazing layer.

HVAC The whole building is equipped with a me-chanical ventilation system. The heating and eventually the cooling of the building are real-ised via the ventilation system. No heat ex-changer is installed in the building.

Façade Type Climate façade (double window system).

Ventilation of the cavity In the offices, the heat produced can be re-moved with the exhaust air. The exhausted air is then brought to the climate façade. Ducts are therefore placed into the false ceiling. The air direction of the façade is from the top to the bottom of the façade.

Façade construction – It consists of a double window and a single Pane type window separated approximately 15 cm from each other. The double window is double glazed at the exterior (U Value ~ 1.8 W/m²K) and single glazed at the interior. The single window is a single pane safety glass.

Shading device type The solar control is situated in the air cavity near the inside glazing layer. It is centrally con-trolled according to the orientation and the storey of the façade. No user control is avail-able.

HVAC The whole building is equipped with a cen-tral mechanical ventilation system. The air is centrally conditioned. The air is distributed in the different offices and is centrally ex-hausted. No heat exchanger on the exhaust air is installed. During the summer, a free cool-ing strategy can be applied if significant tem-perature difference between the inside and the outside is registered.

Comments Measurements and extensive description of the building are given in “Low-energy design and airflow windows, some considerations illus-trated with a case study” of Saelens and Hens.
