Every year humanity faces the problem of saving energy resources and alternative energy more and more seriously. And there are already real steps towards solving this problem. So, in Finland, a house that is completely self-sufficient in terms of energy has recently appeared, the inhabitants of which will be able to do without electricity.
The future, when there will be no need for electricity meters, when electricity will be obtained from wind, sun and heat, is getting closer to reality, thanks to the tireless work of scientists, engineers and architects. So, in the north of Finland there was a "zero energy" house. This name hides a new concept of providing housing with energy resources, which has been gaining popularity in recent years. According to her, each house should fully support itself, and the annual energy consumption of such houses should be close to zero.
Building of this kind is possible today thanks to the use of modern waterproofing materials, thermal insulation equipment and, of course, thanks to a well-planned energy recovery system.
Innovative housing does not (externally) stand out from the surrounding buildings. In appearance, this is the most ordinary house, because all the necessary technologies are integrated into its structure, they are mostly located in the attic, roof and basement. Such a house can receive electricity from wind, sunlight and geothermal heat.
By itself, clean energy production would not make any sense if such a house were not perfected in the field of optimizing electricity consumption. However, "optimization" does not mean that residents will have to give up any amenities. In the summer, the house will provide as much electricity that it can even save or sell the surplus. The most important thing is that houses of this kind already exist today. For example, in Finland, such a house appeared in the city of Kuopio, in the central part of the country, and is a student hostel with 47 apartments. Another such house with 44 apartments was built in Helsinki.
It is worth noting that the ventilation system of these houses uses 80% of the heat that has entered it for secondary heating. Water is heated mainly by solar panels. Even elevators are braked by solar energy. It is no less important that the first of the "zero houses" has been successfully operating for 5 years and all technologies applied in it have proven their worth and efficiency. Back in 2012, a model of an active house for mass construction was proposed in Finland.
This is what one of the energy efficient houses looks like.
However, today tenants of even the most ordinary houses can save money if they purchase stylish gadget that will help you reduce energy costs.
