Ventilation

How do I know if my home is properly ventilated?

The smell of the residence says a lot. Does the air smell stuffy, especially after a longer absence? Is there a feel of draughtiness? Do residents often suffer from the flu? Does the steam after a shower take a long time to evaporate? Issues such as these mentioned, might indicate problems with indoor air.

Cleaning the filters of a heat pump and ventilation system is recommended to be done at least once during both spring and autumn. Regularly cleaning your home also has a great effect on the quality of the air inside!

If problems keep on occurring, contact the deputy landlord. If solutions are not found the city authorities should be contacted.

Can ventilation vents be adjusted yourself?

In apartment buildings multiple apartments are joined to the same ventilation system. A HPAC design engineer calculates the sufficient amount of airflow needed. When adjusting the vent yourself you are affecting the ventilation of other apartments as well. Readjustments require measuring and adjusting each vent separately.

Vents and filters in all ventilation systems must be changed at least twice a year. If the residence has gravitational ventilation or mechanical exhaust air ventilation, ventilation ducts should be cleaned every 10 years. The grease filter of a stove should be washed or replaced every two months. Adjusting the valves of a mechanical ventilation system should be left to professionals.

Supply air vents for gravitational ventilation are adjusted according to the season and outdoor temperature. Vents for gravitational ventilation also come in self-adjusting models. Models where the supply air is heated are also available. Dust filters can be installed to filter the air. When cleaning the vents of a mechanical ventilation system the silencer of the vent should also be cleaned. Changing of the filters is the responsibility of the housing company.

How can I cool my home without consuming energy during the summer?

The most efficient way to keep your home cool during the summer is to use anticipatory methods during the building stage. Passive cooling of the building can be done with the help of various eaves and visors, which keep direct sunlight from entering through the window. External shades can also be used to not only control the heat, but also the amount of light entering the building.

Shielding a building from the sun is most efficient when done from the outside, however blinds installed in between windows is also a good option. Blinds are also protected from weather conditions. When choosing blinds, the colour and materials should be carefully considered. If blinds are not a suitable option, sun shading films or windows made from low energy glazing glass can also be used.

Also, utilising the shrubbery in the garden as shading is handy. Ventilating should be done on the shady side of the building and if possible during the night time when it is cooler.
