Mandatory photovoltaics can make apartments and houses more expensive by up to fifteen percent, developers say – Novinky

“I assume that this will lead to another increase in the price of new houses between ten and fifteen percent,” said the CEO of Ekospol, Evžen Korec, to Novinkám.

Martin Bursík, lead analyst of the Chamber of Renewable Energy and former Minister of the Environment, said in support of the ruling that buildings in the Union are responsible for more than a third of greenhouse gas emissions, mainly from heating and water heating.

“In zero-emissions buildings that will become the standard from 2030, no fossil fuels will be burned and energy needs will be met from renewable sources produced on-site or shared, where can the energy community be a supplier. Remote heat supply will also be possible, but not from fossil sources,” explained Bursík about the desired state.

According to him, heat pumps will play a key role in the heating of buildings, which will gain ground due to their high efficiency. They get three to five units of energy from the unit of energy spent to work. They will gradually replace gas boilers, which will be uneconomical compared to clean sources.

“The apartment buildings will use solar energy and in most cases will be equipped with a heat pump. At least half of the parking spaces should have electric car chargers, and the rest will be ready for installation,” said Bursík.

According to him, it is important for households that the measures are based on a reduction in energy consumption and that the investment has a good return. “The most important thing, from the perspective of the house, is that the energy operating costs of the building will be reduced. The so-called Social Fund, in which the European Union pours large resources, will help the state to take austerity measures,” he believes.

According to him, it will give people a healthier life, it will affect air quality and operating costs will be significantly lower.

Evžen Korec does not agree with this. “Brussels’ current regulation to build zero-energy buildings is an economic embarrassment. The changes, which have already achieved almost zero energy consumption, were the best. A further reduction to zero consumption is not effective, as it will only provide a small improvement in energy consumption at the cost of very high costs. Higher costs will not lead to higher savings,” he says.

Even according to data analysis of the company Datarun Petr Barton, mandatory photovoltaics will make buildings, especially apartments, even more expensive.

“The measure will have the biggest impact on the Czech Republic, because due to unimpressive construction regulation, we have been the furthest behind in house building for years. In addition, the regulation will come into force shortly after the European Union may make apartments more expensive from 2027 by bringing them under the carbon tax,” he told Novinkám.

According to him, the argument that the regulation will make the operation of apartments with photovoltaics cheaper makes no sense. “The potential is already there, and those who see it as valuable are already doing it. There is no obligation to apply. Only those who don’t pay for the panels can profit from it, and they still have to build them,” he said.

According to Karel Kabele, vice-chairman of the Czech Chamber of Authorized Engineers and Technicians active in construction, new buildings in the Czech Republic must meet the requirements for buildings with almost zero energy consumption. According to Korka, this will lead to price increases from 2020.

“Complying with these energy limits required the installation of additional insulation and a recovery system, which made new apartments ten percent more expensive on average,” he said. “The European guidelines are also addresses the effort to increase the use of solar energy in buildings, where it is necessary to include it in all new public and non-residential buildings with a floor area of ​​more than 250 square meters by the end of 2026. said e.

According to him, the important condition “if it is technically appropriate and economically and operationally feasible” is defined in all requirements. Therefore, it will be possible to professionally evaluate each such installation and consider whether it is suitable for the given object.

“But who determines the limit of economic justification? The details will be specified by the order, but the problem is that it is not even possible to determine how much production the solar panel will be profitable,” said Bartoň.

From 2027, all new public buildings must have photovoltaics on the roof. Reworked items will also be added gradually. In 2050, with one exception, all buildings in the Union must be equipped with them.
