The “Jabłoniowa Aleja” housing estate in Choroszcz is entering the final phase of construction and is nearing completion. The investment of Polskie Domów Drewnianych includes 10 two-family houses and 1 service building – all of them made in energy-saving, prefabricated technology using wood. The estate meets rigorous standards in terms of thermal insulation, acoustics and fire safety. The general contractor of the investment is Unihouse.
Since January 1st this year, Poland has been bound by the new Regulation of the Minister of Infrastructure on technical conditions which should be met by buildings and their location. According to this, designed and constructed buildings must have a much lower energy demand for heating, ventilation and hot water preparation, and thus stricter thermal insulation standards. The buildings in the Jabłoniowa Estate Aleja Polskich Domów Drewnianych will more than meet these requirements. Thanks to the fact that individual elements of the buildings were created at the Unihouse factory in Bielsk Podlaski, all thermal bridges, i.e. unwanted gaps through which a building loses heat and energy, have been eliminated almost 100%. Thus, higher costs incurred at the stage of construction will be quickly recouped during operation, and the constructed houses will be ecological and energy-efficient.
The Blower Door Test carried out in the completed turnkey apartment in Choroszcz confirmed that the finished building has excellent insulation of walls, roofs, floors, doors and windows. Thanks to this, future residents will be able to enjoy lower heating bills than in traditional concrete buildings, more efficient air cycling, and above all, a friendly microclimate of houses in the “Jabłoniowa Aleja”.
– Green and energy-efficient construction has been the rule in the rich, developed countries of North-Western Europe for generations. As Unihouse, we are glad that we are more and more often chosen by domestic investors, and wooden construction gains even more supporters. Wood is an excellent building material, and it’s also a renewable resource, making it possible to produce buildings with a reduced carbon footprint. Our customers are already starting to pay attention to what Unihouse has been talking about for years. The amount of the whole investment is not only the amount of construction, but also the time of execution and the total cost of using the facility,” says Roman Jakubowski, Member of the Management Board of Unihouse SA.
Natural silence within your own four walls
At the estate in Choroszcz, care has been taken to ensure high acoustic comfort and soundproofing of the flats under construction. Acoustic measurements carried out using the Bruel & Kjaer method confirm that the soundproofing of prefabricated houses is higher than the applicable standard.
– It is a point of honour for us that future residents should be able to enjoy natural quiet in their homes. We all know that noise from outside or from a neighbouring property affects the comfort of living. Disturbing noises interfere with daily activities and have a negative impact on sleep, rest and regeneration. The results of the acoustic tests speak for themselves. Future residents will be able to enjoy high comfort of living without any unnecessary disturbances – says Tomasz Szlązak, President of the Management Board of Polskie Domów Drewnianych S.A.
Fire safety is a priority
Modern prefabricated buildings constructed using wood are safe and fire resistant. However, how the structure is constructed is crucial. Only prefabricated construction ensures the right level of safety. Only in a factory can the appropriate level of precision be achieved, which translates into durability and safety of the structure, as confirmed by a fire experiment conducted last year by the Building Research Institute and the National Fire Service.
On the premises of the Training Centre of the State Fire Service in Pionki, fire tests were carried out for a wooden two-storey building with an area of 110.5 square metres (parameters similar to those of buildings constructed in the past). (with parameters similar to those of buildings constructed in Choroszcz). The test was observed by approximately 200 experts specialising in fire safety or wooden construction. The results of the experiment fully confirmed the thesis that multi-level, timber frame buildings are fire safe. Characteristic of a fully developed fire, extremely high temperatures exceeding 1000°C did not affect the structure of the wooden building. Moreover, the fire did not spread to the second floor of the building, where the room temperature of 23°C prevailed throughout.
Ecology of Jabłoniowa Aleja
The estate will have rainwater tanks for watering the greenery. Each flat will be equipped with mechanical ventilation with heat recovery (recuperation), and the roofs of the buildings will be adapted for installation of 5kW photovoltaic panels. This will translate into lower maintenance costs.
Completion of the entire investment is planned for the third quarter of this year.
