Energy efficiency tested

One of energoeffektivnyih of the houses were built with the support of the Rockwool is the Green Balance house in the suburbs. In July, the house turned a half years, he worked full heating season — and we can summarize.

Efficiency, comfort, beauty

The Green Balance house that he and experiment (one of the first energy efficient houses in Russia), and part of the life of a very specific young family.

This is Marina and Alexander Owls and their two children, who decided to live in the suburbs they like more than in the city. The village they found a long time ago, there live their friends, their country and so they spent almost every summer weekend.

 

But the house had difficulties: "We went to exhibitions, trying to choose a house on the directories — I can't say that we didn't like, but something was not", — says Marina Owl. Fortunately, with the help of friends, the Owls met with the architects Tatiana and Evgeny Romanov. Them the task to build an inexpensive and economical building seemed interesting — as well as the opportunity to attract consultants Rockwool to work on this project.

And strap from the beginning was set high: to build a house that will be energy efficient — and it will be comfortable and beautiful.

Properly put

The first thing that catches the eye — the angularity of the house, its complex design. But much of it is dictated by the desire to most effectively organize the space and make the building energy efficient by the architecture.

After all, with a total area of 207 sq. m. Green Balance is very compact, because it is stretched up. Compared to building the same area of the house Green Balance is less than the area of the wall means less heat is given to the air. In addition, these walls are oriented correctly. Two solid walls facing West and East: they stand in the way of sunlight to accumulate heat and release it during the day in the room.

But 40% of the walls is glass, which is also located at random. The slopes of the exposed parts of the building are designed so that the summer and winter to capture maximum heat and light. South-East window set at an angle 83 ° to the horizon, and South at an obtuse angle of 100 degrees — in the summer the house is not too hot. As well, some would say: the large Windows is the enemy of efficiency, because through them takes the most heat! In any case, not through the Windows in the house, Green Balance: here double glazing with inert gas filling — it has a thermal conductivity significantly lower than air.

In addition, parts of the walls of the house are made of polycarbonate which also allows light — artificial lighting in the rooms is used only in deep twilight, and even then not everywhere.

Insulation on all fronts

Perhaps most important in ensuring the efficiency of a home is the insulation. It is in the surface of buildings and for each selected his combination of wall material and the type of stone wool Rockwool.
It all starts with the Foundation: here is the prepared ground on first gravel with sand, then hard Rockwool Flor Batts with a thickness of 120 mm. Above it, reinforcing the screed and, actually, Paul.

Brick walls downstairs insulated slabs Venti Batts, and the rest of the wall is a wooden frame with boards light Batts that are suitable for lightweight structures. Outside walls insulated with the system Rockfacade — insulation plus decorative plaster. In total wall received 300 mm of thermal insulation layer. There is insulation in the roof, here its thickness is 450 mm.

And yet, even such a warm house needs heating. On the ground floor Green Balance is a solid fuel boiler, which Filinych family heats with wood.

On the first floor also features a heated floor, which, say the owners, some days is enough for whole house heating: warm air rises from the first floor to the top. On each floor also are the radiators, the heating can be adjusted.

Do not forget the architects and about ventilation. On the one hand, the house is arranged so that it is easy to do and natural ventilation, but there is a Green Balance ventilation system with heat recovery in winter: the warm air leaving the house heats fresh cold, which the house runs.
