Stricter regulations make house building more expensive in 2016

Every year thousands of people want to fulfill their dream of owning their own home. For some years this venture becomes more expensive. New rules drive up costs - to the annoyance of the builders.

According to the consumer center of North Rhine-Westphalia, since 2016 consumers have to observe "stricter energy-saving guidelines" if they want to build a house. KfW Bank has already responded to the new requirements and granted higher promotional loans - but not every German citizen can use them; a higher credit means greater repayment installments.

The requirements of the EnEV 2016 at a glance

Since 2016, home builders have had to take into account the stricter requirements of the EnEV if they want to build a property. EnEV 2016 is the second phase of the Energy Saving Ordinance of 2014. The energy requirements now presuppose that the primary energy requirement is 25 percent lower. In the same period, the insulation must be about 20 percent better.

A single-family home must meet the following requirements:

  • Primary energy requirement : & le; 51 kWh / (m² · a)
  • Specific transmission heat loss :? 0.368 W / (m² · k)

The new requirements apply to builders who have submitted their building application as of 1 January 2016.

Density and Damming

Germans are becoming professionals in sealing and damaging their construction property. Since 2016, stricter rules apply to new buildings; These must be even more economical. Builders can fulfill the criteria in two ways:

  1. they use more district heating or renewable energies
  2. they increase the insulation layer of the outer wall to

. The second variant is generally cheaper. Nevertheless, the total costs increase to reach the new standard. The president of the industry association ZIA, Andreas Mattner, assumes additional costs of up to eight percent; the federal government, on the other hand, expects an increase of only two percent.

The additional costs are offset by low savings through lower energy consumption: Mattner has calculated an average CO 2 annual savings of 0.02 percent.

Bad Opportunities without Renewable Energies

In addition to the insulating layer, home builders must invest in renewable energy, whether they like it or not. The main focus is on an energy-efficient heating technology. But even with condensing boiler oil or gas heating, it will be difficult to meet the EnEV requirements.

In addition to fossil fuel heaters, home builders need a solar thermal system that supports the heating and processes hot water. Or: You opt for a pellet heating system (with / without solar thermal energy) and a heat pump.

The heat pump can be joined by a photovoltaic system: Consuming the produced solar power itself would reduce the primary energy requirement many times over.

Higher Land prices

In addition to the growing demands on the energy standard of a property, real estate prices are also growing in many conurbations. Data from broker association IVD show that land prices in Munich have risen by 17 percent; One square meter costs 1,350 euros on average - twice as much as in nearby Stuttgart.

Munich is not alone with the price development: The magazine Der Spiegel determined in the summer of 2016, the price increases of other major German cities. In Frankfurt, the cost of housing increased by 27 percent in two years, and by 13 percent in Hamburg in one year.

Use of subsidies more important than ever

So far, many homeowners were expecting no subsidies - from 2016 onwards they will take a closer look. The supply of funding is large. The most important subsidies are and will remain the low-interest loans of KfW Bank, for example KfW-Effizienzhaus 55.

In addition to the KfW subsidies, it pays to look at local or regional subsidies.


The new requirements of the EnEV are driving up the costs of housing construction. Home builders must consider the use of renewable energy to meet the stringent requirements. You should also look at subsidies to reduce costs.
