The microclimate in the apartment and in the office

The spaces should protect the human being against rigors of the weather, and an environment gives, that promotes well-being and functional capacity largely. Without air-movement belong to it, easily moved, oxygen-rich air, agreeable Heat, Humidity and a corresponding brightness.
The space-climate becomes air-temperature, temperature, from the components the enclosing-area, humidity, Air-current, Heat-radiation respectively Temperature-radiation and decides the atmospheric pressure. All single-components can be grasped measuring-technically.

The human being is relatively temperature-sensitive, he/it is a thermo-philic nature. Its life-conditions are in a relatively small temperature-area and he/it is biologically seen heat-needy. Its kernel-temperature is enclosed with 37 °C and this of the body-peel < 37°C. His/its heat-balance sheet sits down from the heat-production (metabolisms, convection, direction, radiation) and the regulators, like convection, direction, radiation and evaporation, together. The heat-requirement must be met by corresponding food-supply. By the blood, this is transported at the skin-surface. Through radiation, convection, direction and low evaporation, the body-temperature attaches importance to a certain value. With normal temperatures, a moderate-sized slim human being gives about in silence on the day. 1 liters of water from. The evaporation is dependent on the humidity, the evaporation-plain and air-speed. From an air-temperature of 35°C, the refrigeration of the human being takes place almost exclusively through evaporation, what 2450 kJ /l fluid corresponds.
According to use of the spaces, whether to living, working or for sport, different temperature-requests are put.

Labor performance Comfort-

Mental work 20-23 35-70 20-40 0,1

Heavy work 14-17 35-70 60-90 0,5

Here a suggestion of the Berlin finance-senator Thilo Sarrazin (SPD) of too high energy costs, however, the people should save and one could live sensibly also with 15 or 16 degrees of room-temperature with a thick sweater.[2] this remark needs no commentary.

According to the Swiss Norm ISO, the optimal space-temperature should 7730 with easy and sedentary indoor service as well as wintry office-clothing (Wärmedurchlasswiderstand 0,15 m2K/W) with 21,5ºC +/- 2,5 K lies. The thermal comfort is felt individually and is recorded statistically. In the norm, the comfort-conditions are regarded as appropriate if the preconditions find 80 per cent of the people with normal activity and season-usual clothing cozy.

The temperature of the environment-plain should not amount bigger than 2 to 3 K opposite the space-air-temperature. As well, this applies also to the height (ankle until head). At badly isolated wall-plains, partially bigger differences occur in the winter, sees table of the cases in point), what leads to a negative heat-radiation and is found unpleasant. If the relative humidity is high to it, so mold can refine very fast at the wall-surface.
With climatic changes, like for example with the heat-climate, the body requires an adaptation of 1 to 2 weeks. The body gets ready for a lower salt-delivery with the perspiration-formation. In bigger heights from about. 2500 m, the body must adapt itself to the changed atmospheric conditions before heavy physical working should be performed. After the adaptation, working are possible as far as to a height of 5000 to 6000 m (> 0,48 devoid of).

Supplement: The weather or the inaccurate name "the global climate", where prognoziert (climate-models) future weather-events on the basis of passed weather-data1, and measures for the Klimaschutz2, should be derived, "Environmentalismus is, an ideology, that talks about the nature conservation, this however this topic liked for the people as a detour for the radical transformation of the human company uses." [1] in the center was allowed to political power - and economic claims of influential interest groups stand. It can therefore not be offered to an evaluation and composition at the moment. You/they find amounts technology and science in the data bank to this topic or in the contribution Weathers.

1, Prof. Dr.. Andreas Troge: "The model-bills clarify what was allowed to come with the climate-change on us. This helps us to adjust us to these inevitable consequences in time.".. "However, climate-models don't deliver any predictions to the future over the climate. Climate-models represent only possible climate-developments and give information about risks of the regional climate-development so." [2] the two statements in an acticle needs no further commentary.
2, one can protect from weathers, but not before the climate
