Most of the residents are looking at energy-efficient construction with only hand opportunity to get lower bills for heating homes. But much more important component of energy-efficient homes is the highest comfort of living and a positive impact on the health of residents.

The first thesis is confirmed by a survey of owners of energy-efficient homes. When evaluating the advantages of this construction:
in the first place they put the question to save the feeling of operation at home. Such responses 47%. — The following places are occupied by the answers that the owners estimate the benefits to the environment (22%), — quality of life and comfort (16%) — and a positive impact on the health & rsquo; I (12%).
Although most residents have left the question of health & rsquo; I was in last place, namely energy-efficient homes allow to maintain health & rsquo; I am in good condition.
Important factors High comfort of life in energy-efficient homes are:
High indoor air quality — Thermal comfort — optimum illumination as natural light and artificial — interior decoration made with low-emission materials — acoustic comfort, — Friendly and comfortable home environment using them.
High indoor air quality is guaranteed by a balance between adequate ventilation, temperature and humidity, and must ensure that the right is designed and made low-energy house. Numerous studies show n & rsquo; the connection between air quality and various diseases, including various allergies. There is a term — «sick building syndrome», which is rooted in the 70s of the last century. Air comfort achieved by the installation and operation of supply and exhaust ventilation with heat recovery.
Thermal comfort is dependent on factors such as temperature and humidity, air speed and the average temperature of obstacles. The energy-efficient homes all elements of obstacles: walls, floors, ceilings, windows — are characterized by low values of heat penetration. This provides a consistent and sufficiently high internal temperature of the wall, which is slightly different from the temperature of other obstacles. This greatly improves the feeling of thermal comfort for residents who are in this room.
Energy-efficient houses (atut.at.ua/proekt_tut.pdf) placed so as to obtain a better coverage of natural south. Longer daylight in the home greatly improves the well-being and health & rsquo; I. An additional advantage is the saving of energy used for lighting.
The better insulated house, the less external noise gets inside, the & nbsp; a great acoustic comfort of tenants. Ventilation systems are designed such as to divide the acoustic environment: internal and external.
Obviously, such a house is made of high-quality low-emission materials. This first attached builders using paints, varnishes and adhesives of those types that do not emit volatile organic compounds (Engl. Volatile Organic Compounds, VOCs). For the matte paint, for example., This figure should not exceed 30 g / l. Organic products are certified Ecolabel, which confirms environmental quality. For fugues and adhesives should look for products with a certificate of GEV EMICODE EC1 with a high level and EC1plyus.
New construction is carried out such that minimal damage to the environment. To do this, choose materials that can be disposed of without harming nature, achieve savings in water consumption, compact inscribe new building into the landscape, minimize the generation of municipal waste, and optimal use of transport. The idea of ecological buildings should be out of respect for nature, and gives residents a sense of closeness to the natural. This contributes to a more environmentally healthy lifestyle.
Consumption of a small amount of energy for heating and hot water allows you to install energy-efficient homes in more expensive, but more environmentally friendly heating system (heat pump, solar collectors, pellet boilers). In this case it requires smaller capacity heat source and means for returning faster installation. In addition residents receive «hands-free» — these systems do not require that residents cut down, and were worn wood — automated systems work with minimum human involvement.
