Low-energy homes are energy-efficient and cost-effective homes that satisfy high environmental standards and offer a high level of comfort to the user due to their innovative approach to living, in a pleasant climate throughout the year. They are also called cost-effective homes. The name comes from their extremely low consumption of energy. The costs of heating and cooling in such homes are 60-90% lower than in standard buildings: due to thermal insulation, the house does not use up more than 40 kWh, i.e. 2.7 litres of light distillate oil, per m2 per year. The cost-effective house does not use standard systems of heating and cooling – the priority in its design is the maximum use of solar energy, which is achieved by its south-southwest positioning. In addition to its energy efficiency, another reason why a low-energy home is an example of sustainable construction is its environmentally acceptable construction material and the rational use of the energy sources. A shorter construction time and lower costs of maintenance of such home should also be noted. A low-energy home can be turned into a so-called passive house that uses only 15 kWh for heating, i.e. a litre of light distillate oil, per m2 a year. Such house is based on the concept of sealing and controlled ventilation: by installation of a ventilation system for recirculation of air and additional thermal insulation, a low-energy home simultaneously becomes an accumulation house, which means that it has the ability to retain thermal energy. In terms of sustainability and cost-effectiveness, so-called zero energy homes go beyond the passive house – such homes produce all the energy needed for living independently, which makes them self-sufficient and independent in terms of energy. In some cases, they can even produce surplus energy. In Croatia, which has not yet developed the system of inciting the construction of cost-effective homes, this trend is still young, but due to fast construction, comfort and minimum energy costs, the low-energy home is, in the long run, a lucrative investment, increasingly recognized by investors. Low consumption of energy can be attained in the reconstruction of the existing buildings, which opens up the possibility of turning your home into a cost-effective home.

Niskoenergetske kuće su energetski učinkovite i financijski isplative kuće koje zadovoljavaju visoke ekološke standarde i svojim inovativnim pristupom stanovanju korisniku pružaju visoku udobnost stanovanja u klimi ugodnoj tijekom cijele godine. Nazivaju se još i štedljive kuće, a to su ime dobile zbog izrazito niske potrošnje energije. Troškovi grijanja i hlađenja u takvoj će kući biti 60 do 90% manji nego u klasično građenim objektima: zahvaljujući termoizolaciji kuća ne troši više od 40 kWh odnosno 2,7 litre lož ulja po m2 godišnje. U štedljivu kuću nisu ugrađeni standardni sustavi grijanja i hlađenja već se pri njihovoj izgradnji vodi računa o maksimalnom iskorištavanju sunčeve energije, što se postiže orijentacijom na jug i jugozapad. Pored svoje energetske učinkovitosti, niskoenergetska kuća primjer je održive gradnje i zbog građevinskog materijala koji nije štetan po okoliš te racionalnog trošenja izvora energije, a valja istaknuti i bržu izgradnju te jeftinije održavanje takve kuće. Niskoenergetska kuća se uz dodatne investicije može pretvoriti u tzv. pasivnu kuću koja za grijanje i hlađenje troši svega 15 kWh odnosno 1 litru lož ulja po m2 godišnje. Takva kuća zasniva se na konceptu zabrtvljenosti i kontrolirane ventilacije: ugradnjom ventilacionog sustava za recirkulaciju zraka i dodatne toplinske izolacije niskoenergetska kuća postaje ujedno i akumulacijska, što znači da ima sposobnost zadržavanja toplinske energije. U održivosti i ekonomskoj isplativosti još dalje od pasivne kuće ide tzv. nulta kuća koja samostalno proizvodi cjelokupnu energiju potrebnu za stanovanje u njoj što je čini samodostatnim i energetski neovisnim objektom koji u nekim slučajevima može proizvoditi i viškove energije. U Hrvatskoj, koja još nije razvila sustav poticanja gradnje štednih kuća, ovaj trend je tek u začetku no svojom brzom izgradnjom, udobnošću i minimalnim energetskim troškovima niskoenergetska kuća je dugoročno isplativa investicija koju prepoznaje sve više investitora. Niskoenergetska potrošnja energije može se postići i u obnovi već postojeće gradnje, što otvara mogućnost da i Vašu kuću pretvorite u štednu kuću.
