The passive house is an ideal housing solution for incredible energy savings while ensuring good health and pleasant residence. It respects the principles of sustainability and reason to be the concept and for the present and the future. Passive house meets all the requirements posed by ethics, ecology, economy and energy. It is energy efficient, cost effective, convenient, economical and environmentally sustainable.
Wisely thought out architecture, highÂ standards of construction, advanced technologies and electrical systems, andÂ using renewable energy; passive house itself can produce the required amount ofÂ energy. Decades of experience have shown that energy prices are on a constantÂ rise, and often happened that the price rose above the anticipated “worstÂ case scenarios”.
In passive houses, air conditioning usesÂ filters that clean the air of dust, insects, pollen and other undesirable elements.Â Due to the microclimate of an automated system that consistently works to suckÂ in air from the outside, if necessary, it warms or cools the interior, and itÂ ventilates the room – the passive house will feel comfortable and people withÂ serious problems when it comes to pollen allergies. Given the high efficiencyÂ of ventilation systems, occupant of passive object do not have to open windowsÂ to ventilate the place if they donâ€™t want to.
On the other hand, there is a system ofÂ passive houses that positively affects residents to stay healthy. It is aÂ system of surface heating and cooling of ceilings and wall surfaces, where theÂ effect of “raising the dust” reduced to a minimum, which drasticallyÂ reduces the discomfort to all those who are allergic to dust. Surface heatingÂ system in a passive house is also a great friend of children who often spendÂ their time on the floor playing.
Passive houses can use solar energy,Â groundwater, geothermal, and even the accumulated heat in the rooms thatÂ tenants and household appliances produce. These same savings are reflected inÂ the entire country, and its influence on the reduction of investment supply. ItÂ is extremely important information because there still is a large number ofÂ countries that depend on energy imports. The geographical location of BosniaÂ and Herzegovina gives a lot of sunny days a year, so passive houses have greatÂ potential exploitation of gains provided by the sun – solar hot water withÂ collectors, photovoltaic cells produce electricity and heat radiation throughÂ the glass surface heats the inside of the building, which are well-insulatedÂ buildings that has a free “passive” heat gain.
Often, one can hear or read that howÂ important it is to work on reducing the use of conventional energy sources andÂ greenhouse gases, because it is self-evident. However, there is stillÂ widespread general lack of information about the said issue that forces us toÂ yet again repeat that the planet Earth is not our property. We just borrowed itÂ from our children and grandchildren. Imagine yourself on the fact that todayÂ the heating and cooling of buildings accounts for about 40 percent of totalÂ world energy consumption, while passive house reduces energy consumption up toÂ ten times.
EuropeanÂ Environmental Goals
The number of passive objects in the world isÂ increasing on a daily basis, mainly thanks to the European Union, which wants allÂ of their new buildings to fully switch to passive standard by 2020.
In 2007, the European Union has adopted theÂ popularly initiative called the 20 / 20 / 20 that legal acts in to reduce the impactÂ on climate change. The goal is to achieve:
Â·Â 20% lessÂ greenhouse gas emissions in comparison.
Â·Â 20% shareÂ of renewable energy in total energy consumption.
Â·Â 20% energyÂ efficiency.
Given the enormous cost savings and focus on passiveÂ houses and renewable energy, and if we take into account the fact that such a savingÂ system drastically reduces the emission of greenhouse gases – it is a completelyÂ logical decision on the compulsory introduction of EU standards in the passiveÂ construction.
MandatoryÂ energy certification
Passive house in the highest (A +) EnergyÂ Class.
Energy certificate gives insight into howÂ much energy actually spend by buildings, houses and public buildings. All theÂ buildings are divided into 8 classes: A +, A, B, C, D, E, F and G. BetweenÂ class A + (construction whose annual energy consumption for heating and coolingÂ does not exceed 15 kWh/m2) and worst grade G (constructions which consume moreÂ than 250 kWh/m2) obvious difference, which certainly affects the level of (non)qualityÂ of housing and the amount of monthly utility bills. According to expertÂ estimates, 85 percent of buildings in Bosnia and Herzegovina are categorizedÂ into classes D and E, while the new buildings are built under class C. In suchÂ poor competition, the passive houses with its A + rating receives additionalÂ marketing and market value, which further justifies the economic viability ofÂ investing in a passive construction.
