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, high standards of construction, advanced technologies and electrical systems, and using renewable energy; passive house itself can produce the required amount of energy. Decades of experience have shown that energy prices are on a constant rise, and often happened that the price rose above the anticipated “worst case scenarios”.

Health

In passive houses, air conditioning uses filters that clean the air of dust, insects, pollen and other undesirable elements. Due to the microclimate of an automated system that consistently works to suck in air from the outside, if necessary, it warms or cools the interior, and it ventilates the room – the passive house will feel comfortable and people with serious problems when it comes to pollen allergies. Given the high efficiency of ventilation systems, occupant of passive object do not have to open windows to ventilate the place if they don’t want to.

On the other hand, there is a system of passive houses that positively affects residents to stay healthy. It is a system of surface heating and cooling of ceilings and wall surfaces, where the effect of “raising the dust” reduced to a minimum, which drastically reduces the discomfort to all those who are allergic to dust. Surface heating system in a passive house is also a great friend of children who often spend their time on the floor playing.

Energy

Passive houses can use solar energy, groundwater, geothermal, and even the accumulated heat in the rooms that tenants and household appliances produce. These same savings are reflected in the entire country, and its influence on the reduction of investment supply. It is extremely important information because there still is a large number of countries that depend on energy imports. The geographical location of Bosnia and Herzegovina gives a lot of sunny days a year, so passive houses have great potential exploitation of gains provided by the sun – solar hot water with collectors, photovoltaic cells produce electricity and heat radiation through the glass surface heats the inside of the building, which are well-insulated buildings that has a free “passive” heat gain.

Ethics

Often, one can hear or read that how important it is to work on reducing the use of conventional energy sources and greenhouse gases, because it is self-evident. However, there is still widespread general lack of information about the said issue that forces us to yet again repeat that the planet Earth is not our property. We just borrowed it from our children and grandchildren. Imagine yourself on the fact that today the heating and cooling of buildings accounts for about 40 percent of total world energy consumption, while passive house reduces energy consumption up to ten times.

European Environmental Goals

The number of passive objects in the world is increasing on a daily basis, mainly thanks to the European Union, which wants all of their new buildings to fully switch to passive standard by 2020.

In 2007, the European Union has adopted the popularly initiative called the 20 / 20 / 20 that legal acts in to reduce the impact on climate change. The goal is to achieve:

· 20% less greenhouse gas emissions in comparison.

· 20% share of renewable energy in total energy consumption.

· 20% energy efficiency.

Given the enormous cost savings and focus on passive houses and renewable energy, and if we take into account the fact that such a saving system drastically reduces the emission of greenhouse gases – it is a completely logical decision on the compulsory introduction of EU standards in the passive construction.

Mandatory energy certification

Passive house in the highest (A +) Energy Class.

Energy certificate gives insight into how much energy actually spend by buildings, houses and public buildings. All the buildings are divided into 8 classes: A +, A, B, C, D, E, F and G. Between class A + (construction whose annual energy consumption for heating and cooling does not exceed 15 kWh/m2) and worst grade G (constructions which consume more than 250 kWh/m2) obvious difference, which certainly affects the level of (non)quality of housing and the amount of monthly utility bills. According to expert estimates, 85 percent of buildings in Bosnia and Herzegovina are categorized into classes D and E, while the new buildings are built under class C. In such poor competition, the passive houses with its A + rating receives additional marketing and market value, which further justifies the economic viability of investing in a passive construction.
