Energy-saving house - a life without unnecessary expenses

energy house at the stage of design and preparation for construction

choose the right place for your future energy house - this is the basis, this is where you start counting the savings in future funds.Place it in a valley where the ground temperature is always low enough, and your foundation will be constantly exposed to incessant assault from the chilly dampness, using defense all the thermal resources at home.Build houses on the hill, and the house will literally be throwing the heat to the wind, because of which the energy consumption for heating will rise sharply. ideal place for the house - on the slope, more precisely, on its southern side , where it will be, and protection from north winds, and moisture that accumulates at the foot of the nameless heights.No matter how prepared is the foundation for the house, it can be dug in the hillside area or artificially created terrace, pour in a pre-arranged on the side of the fence.

If you decide to build energy-efficient housing on the basis of common today in Germany, passive houses, it is advisable to rent a mobile drilling rig and drill wells for groundwater heat pump circuit.However, this process is quite expensive, so you can get a cheaper option of ground collector, which is laid under the ground in a specially dug trench (which requires some free space).If such a system does not suit you, you can do just one thermal insulation of the building.And to begin, of course, should be a basement or ground floor.Roy pit and a half height of a man, that is, about 3.5 meters, so that the basement was spacious.The easiest way to dig on the slopes of a pre-prepared site, which was mentioned above.

to build a house on the ground terrace, it should be prepared at least one year, lest the land managed packed.

primarily provide home insulation from the ground, which should be laid on the bottom of the pit so wonderful insulation as foam glass, without joints and gluing the side surfaces each other.On top of polyethylene film is laid on top of which you are linking reinforcement for reinforced concrete foundation pads.Along the perimeter of the vertical rods are welded fittings, wall basement and set on top of the horizontal lattice formwork.Fill the resulting concrete mix design, eventually getting monolith insulated foundation and walls.If the underground floor includes interior walls for them is also preparing in advance reinforced crate, but poured it later, after curing the outer "box.All air channels, including the basement and ventilation, electrical cables and other home networks are located in this same crate where and filled with concrete.

Energy-saving technologies for the house with minimal cost

So, we have in stock the box with heat-insulated basement foundation, which is located in the pit, the walls of which depart from our construction of approximately half a meter.This gives us the freedom of action on the outside of the buildings, where it is necessary to paste over the same cellular glass every wall.It is important to follow the technology - it is necessary to smear glue the entire plane of the plate heater, using a notched trowel, only then it will be possible to ensure the strength of fasteners.Warm walls 2 meters from the bottom of the pit, you can use some more energy-efficient technology for the home, namely - to pave the ground heat exchanger pipe.However, he made only in Germany, but the transportation costs of the pipes will be fully justified: passing through a heat exchanger, outdoor air is heated in the winter cold at least until the zero temperature.By connecting to the heat exchanger ventilation system with heat recovery (that is, its own heat transfer), we can expect that ventilation will not freeze.In this heat exchanger will be run more efficiently.

to lay ground heat exchangers, it is enough to fill the gap between the walls of the pit box and basement ground half a meter thick (periodic with tamper), leaving on the surface a series of panels of insulation.On the ground stacked heat exchanger tube, and then backfilled with coarse sand, and on top of all of the same ground previously taken out of the pit.We continue to insulate the walls of cellular glass, reaching the cap of the building, the pit fell asleep almost to the edge, between the ground connecting parties close to the surface of the heat pump pipe system to the outer contour of the soil.Fully pit fall asleep, and then the insulation of the blind area, followed by its laying.Now the lower part of the house is completely isolated from the cold, go to its walls and roof.

energy house with his own hands, the final stage

house without walls and roof - not home, so start to lift a brick wall from the concrete plinth, which is already glued insulation boards.The wall thickness in a brick, that is, 25 centimeters, given pasting them on the outside of the foam glass will be enough.Pasting continue from the slabs, which is the basement, with no gaps, promazyvaya joints between the individual elements.Since the material has excellent hydraulic and vapor permeability, and other insulating materials will not be necessary.Insulation boards made of foam silicate glass are displayed to the roof, connection with insulation roof.Ceilings are insulated by the same cellular glass, which are applied on top of floor fillers or penopolistirolbetonnaya screed.Immediately prior to laying the flooring, you can make the system "warm floor".

The roof is covered with two layers of insulation: the underside of the crate under the slabs between rafters stacked end to end, with no gaps.Above the rafters and battens laid a second layer of insulation.As such, you can use high quality basalt fiber ( low as mineral wool can be dangerous to health ).However, since we are insulated with foam glass wall, it is best to perform and thermal insulation of the roof, and so that the lower layer has been laid with dvadtsatisantimetrovym release the edge of the wall.This will connect the roof and wall insulation in a closed envelope around the home, eliminating the occurrence of bridges for the leak of heat premises.

Check for leaks, provided high-quality insulated glass units, is carried out the only possible way: the room is installed measuring equipment, then pumped under high air pressure.If an artificial high-pressure zone of the readings are changing very slowly or not at all changed, so the tightness is fully observed and accommodation really get energy efficient.
