The choice of the type of your future home should not be arbitrary.
There are many reasons for selecting a log house - healthy living environment, proximity to nature or a wish to have a stylish home.
However, a hope to build a cheap house is not among the reasons as the price of a decent log house will not be lower than the price of any other type of house.

An unquestionable advantage of a log house is its healthier environment as compared to other types of houses.
Regardless of the type of a house (wooden frame, log or stone) the main function of the outer wall is to keep temperature and protect from wind. In case of a log wall these requirements are fulfilled by exactness - each log has to copy the pervious one as exactly as possible. However, in stone and wooden frame walls several hermetic materials and windproof and humidproof layers are used besides isolation material. The result is usually an almost totally hermetic wall.

According to the building requirements, for normal living environment the air in the rooms should be changed 1.5 - 2 times an hour. In other words, per every person inside 6 - 10 litres of fresh air per second should flow in the building. It means that in a dwelling house with a surface of 150 m² the hourly circulation of air should be 400 - 600 cbm or 100 - 150 litres a second. If such a quantity of air had to enter the house through a 20x20 cm opening, the air flow in the opening would be 4 - 6 m/s.
To guarantee such a circulation, contemporary dwelling houses are equipped with a sophisticated ventilation system that has to guarantee sufficient inflow of air, its warming to room temperature, equal distribution in different rooms of the building, and also elimination of used air. However, such ventilation systems are very expensive and it is very difficult to keep them functioning properly. Unfortunately, in practical life one can quite often feel airflow (draught) - sometimes cold, sometimes warm - in the vicinity of ventilation openings. In the worst case, these openings that supply the house with fresh air will simply be sealed one day...
In older houses and apartment buildings ventilation openings can only be found in kitchens and bathrooms and only windows and doors let in fresh air. Unfortunately, the "living environment" in such rooms is characterised by lack of fresh air, draught, overheated dry air, and dust particles that fly in the air because of static electricity.

The temperature keeping properties of log walls and the inner climate of a log house have probably most thourougly been studied in North-America and Finland. The reasons for such studies have primarily included a more economical use of energy resources and the sale of electricity meant for heating houses at a more favourable price.
Such studies and experiments have shown that the flow of heat in a massive log wall is "an enormously complicated issue" that would not follow the equations of physics and cannot therefore be exactly calculated. It appeared that in case of massive outer walls the loss of heat energy cannot be calculated solely on the basis of the heat conduction index of the wall material. The actual heat loss of a log house is much smaller than the calculated loss.
Therefore, the American National Bureau of Standards ordered an experiment that lasted from 1981 to 1982. During 28 weeks different types of outer walls of houses were compared. In total, six 6x6 m identical houses with different types of outer walls were tested. Also, a 7-inch (17 cm) log wall was compared with a wooden frame wall. The latter was designed to keep warmth 17 per cent better than the log wall. The temperature was kept at 20°C in all the houses all through the experiment. The heat energy needed to keep this constant temperature in the houses was measured. The test gave the following results:

• in spring period the energy consumption of a log house was 46 per cent smaller than the consumption of a timber frame house;
• in summer, the log house needed 24 per cent less energy for cooling the air;
• in winter time with constant frosty weather the energy consumption of the log house was comparable to that of the timber frame house.

In total, the log house consumed about 30 per cent less energy during the experiment than the timber frame house. Similar experiments have also been conducted in Nordic countries.

Advantages of a log house

In a log home there´s always enough fresh air. The air needed for normal life enters the log house through outer walls; there´s no need to build expensive ventilation systems or open any windows. There´s no draught in a log home.

The air that slowly enters the building through the walls has gained room temperature by the time it enters the house as the wall of a log house acts as a heat exchanger.

Thanks to a great heat storage capacity of the walls the temperature never abruptly changes in a log house. Because of that log house is comfortably cool in summer and warm in winter. The temperature in an unheated log house equals the average outer temperature of twenty-four hours. In a log house the heating period starts later and ends earlier.

Massive wooden walls keep also the air humidity in normal range.

Thanks to natural materials log houses are free of static electricity and flying dust.
