What is a low-energy house 4 basic criteria differ among themselves houses exactly opbergbak as it is for cars 1. Price 2. Comfort 3. Effectiveness 4. Consumption Since the price of conventional energy is still higher because stocks are reduced, it is important to ensure CONSUMPTION house, you are going to build. Also planned future sale of the house afterwards think that low consumption house will guarantee the recovery of investment and attract the attention of potential buyers. opbergbak Low-energy house house (abbreviation NED) for heating consumes 15-50 kWh / m2 occupied area. For comparison, today's classic house consumes c ca 90-150 kWh / m2 which is up to 90%. Benefits NED NED houses houses are built of different building materials - brick houses of brick and aerated concrete blocks, prefabricated wooden houses from solid wood segments. The division between ordinary house (the current building), opbergbak low-energy and passive house based on the total energy consumption, which means a different amount of financial costs for the use of the house.
Fig. 1 Division of works under heat consumption (in kWh / m2 / year) Source: www.iepd.sk What affects the amount of energy consumed in the house - way of heating a house - a method of heating water - type electrical appliances - type of insulation materials for building - type windows As the door and lose heat in the house - up to 25% of heat escapes through the walls, floor, roof of the house - up to 35% of heat escapes through windows, doors and ventilation caused by leakage nine basic principles opbergbak to achieve low energy house: 1. Creating buildings with sufficient thermal Insulation stripping the house from the ground and from ground moisture 2. The insulation of walls and roofs of buildings 3. Heat-insulating glass 3 with thermal insulating window opbergbak frames *** quality home insulation is defined heat transfer coefficient "U" opbergbak and can be easily compared in this table, which lists the values in various types of buildings. What is the value of "U" lower, opbergbak the better insulated the building:
Source: www.iepd.sk These values can be achieved for all systems opbergbak design (wooden, brick, brick, opbergbak concrete). The differences are only in the very composition of the walls and the required insulation thickness. Given that low-energy houses are also the ecological construction, preferred renewable building materials that are friendly to the environment and create a healthy indoor climate. 4. airtightness of buildings with leaking construction of the outer packaging occurs due to wind flow of air through leaks, build it cools and is the cause of significant heat leaks. It is important to design and ensure all joints opbergbak in the construction of the outer packaging, vapor barrier and method of installation of windows (it must be banded with a special tape joints window frames and walls). 5. The orientation of the house - passive solar heat gains of using solar energy in low energy house is cold and winter essential element for heating the house, which replace conventional heating. The largest heat gains achieve orientation of the house to the south, the optimal ratio of glazing is about 30% of the total area of the south wall. Solar radiation penetrates through glazed openings opbergbak - ultraviolet sun rays are passing through glass window changes to = infrared heat. (Windows, opbergbak doors, conservatories) and energy opbergbak as heat accumulates inside the house. In summer home simply protect against overheating by window louvers, exterior blinds, Sliding walls, sealing layers in the structure window overlays construction (brackets, canopies) or deciduous trees in front of the facade. 6. recuperation opbergbak recovery is heat transfer. Regenerative unit is using equipment in the winter indoor stale warm air to heat the exterior opbergbak clean, but cold air. 70-80% of the energy of useless stale air during the implementation process forward fresh air. The house is vented in this way without opening the window openings and thus escape from it accumulated heat. Controlled ventilation thus saving the cost of home heating. Using the appropriate anti-allergy filter cleans the incoming air, which is a suitable opbergbak solution for allergy sufferers. 7. By burning passive heating = heating natural sunlight sunlight passive heating in the winter months we will reduce energy consumption opbergbak for heating opbergbak by 10-25%. The transitional spring and autumn months of passive solar heating house replaced the consumption of conventional energy. The principle of converting light to heat the glass - ultraviolet sun rays are passing through glass window changes to = infrared heat. The advantages of passive solar heating - natural solar heating is healthy, organic, from the inexhaustible source and free. Primary heating = fundamental source of heat (radiators, floor, wall heater, Infra ...) Floor
