HOUSE ASSEMBLY

Increasing ecological awareness, energy prices and knowledge about limiting fossil fuels and the necessity of reducing emissions of harmful gases into the atmosphere have led to the construction of so-called low-energy buildings. With their excellent insulation properties, they are the optimal solution when it comes to low energy consumption.

The criterion for classifying a building as a low-energy building is limiting its energy consumption to 48 kWh/m2/year. By building low-energy buildings with negligible additional investments (from 5% to 10% of the total investment) and due to the short payback period, we achieve significant energy savings. It should be emphasized that 70% of total energy consumption goes to heating the premises. At the same time, the construction of such buildings achieves an extremely significant reduction in harmful gas emissions (CO2). For example, a low-energy building emits almost twice as many harmful gases annually as a building built on the basis of basic building regulations, while a "passive house" as the "most extreme" example of a low-energy building emits up to 5 times less than a low-energy building.
Na primjer, niskoenergetska zgrada godišnje emituje skoro duplo više štetnih gasova od zgrade izgrađene na osnovu osnovnih građevinskih propisa, dok “pasivna kuća” kao “najekstremniji” primjer niskoenergetske zgrade emituje i do 5 puta manje od niskoenergetske zgrade.

ANNUAL ENERGY CONSUMPTION KWh

Low energy consumption buildings in the west are a concept on which the present in construction is absolutely based.

The chart does not show poorly insulated buildings of classic construction that consume > 250 KWh/m2/year. ie >25 l/m2/year.

Low-energy standard - is an integral part of prefabricated construction and, compared to classic construction, ensures energy savings of 60% to 90%. If the consumption standard of up to 40 kWh/m2 is reached, such low-energy buildings are called "three-liter houses" because they consume 3 liters of oil per m2 and represent an ideal example of a low-energy building.

ZERO HOUSE

A zero-energy house is a house that fully meets all its energy needs. Along with reduced energy consumption, this type of construction reduces environmental pollution and emissions of harmful gases because waste is also managed rationally.

In addition to great energy savings, low-energy buildings stand out with a unique construction technology made of natural and ecological materials that are recycled, which are significant advantages compared to the classic building construction system.

ASSEMBLY CONSTRUCTION

Wie auch die klassische Bauweise beginnt der Fertigbau mit dem Fundament des Hauses, das aus Beton, Betonsteinen oder auf Pfählen errichtet wird. Die Wände bestehen aus tragenden Holzkonstruktionen, verkleidet mit feuerfesten und wasserfesten Gipsfaserplatten mit Mineralwollefüllung, mit eingebauter Dampfsperre an der Innenseite der Außenwände. Die Tragkonstruktion besteht ebenfalls aus imprägnierten Holzbrettern, außen sind die Wände mit Styropor und Holzlatten oder sog. Latten verkleidet. Fertigstellung - Demit-Fassade. Die Zwischenbodenkonstruktion besteht aus Gitterträgern mit Gipskartonverkleidung und der erforderlichen Isolierung, die Dachkonstruktion aus Gitterholzträgern. Auf die Oberseite des Balkens wird eine vollflächige Schalungsplatte aufgelegt, darüber wird eine Pappe gelegt, auf der die Dachstützen und die Dacheindeckung aus Ziegeln, Ziegeln oder Blech befestigt werden. Auf der Unterseite wird eine dünne Schalung aufgelegt, auf der PVC-Folie als Dampfsperre und Mineralwolle als Dämmung angebracht sind.

Heat retention is exceptional, as there are no cold bridges, and the entire amount of energy required can be produced from renewable sources. Another advantage is speed, as a 100 square meter building can be built in 15 days. Such houses also effectively absorb noise coming from the street or from inside, thus creating a pleasant atmosphere. Environmental protection is the primary goal of low-energy buildings and maintains ecological awareness from the origin of raw materials, their production, packaging, transport, to construction and use with the possibility of 100% recycling.
Zaštita životne sredine je primarni cilj niskoenergetskih zgrada i održava ekološku svest od porekla sirovina, njihove proizvodnje, pakovanja, transporta, do izgradnje i upotrebe uz mogućnost 100% reciklaže.

Takođe, prilikom izgradnje na gradilištima ne nastaje otpad, jer se elementi koje gradimo po našim projektima i skicama dovoze iz fabrike, skladište i seku sa milimetarskom preciznošću. Potrošnja energije koja se javlja u ovom procesu je minimalna u poređenju sa klasičnom gradnjom. Kuća se lako može pretvoriti u samoodrživu, uz niske troškove u smislu energetskih potreba. Ovo nam omogućava da zadovoljimo naše potrebe iz prirodnih, obnovljivih izvora energije, istovremeno štiteći životnu sredinu.

LOW ENERGY CONSTRUCTION

Prilikom projektiranja moramo uzeti u obzir sljedeće kriterije:

A building of compact volume
Good thermal insulation of the entire building envelope, insulation of internal rooms from unheated rooms
Avoidance of thermal bridges
Windows must be at least double-insulated glass, with high thermal properties, with a good seal, k<1.50W/m2K
The use of renewable energy sources in passive and active means for obtaining hot water and electricity production (photovoltaic cells, etc.)
Appropriate home technology (solar preparation for obtaining hot water, controlled ventilation with heat recovery, heat pumps, etc.)
Placement of communal areas to the north
The south side is glazed and open, the north side is closed
Analysis and alignment of surface light openings
Additional protection from the summer sun
The possibility of double-sided ventilation through the windows
Provide forced ventilation
The possibility of pre-heating the air before entering the space
