Indoor and health conditions
If a house is energy efficient, it will also be a healthier place to live. The fact is that the energy in your home is used primarily to maintain a comfortable environment where temperature, humidity and air quality are well regulated. Energy also provides a driving force for a modern and hygienic lifestyle in which every device and appliance used uses energy to achieve the desired result.
If energy is used in almost every aspect of home operation, unless properly managed, your real profits will simply leak out of your home.
Comfort conditions
Regardless of the geographical location of your country, the nationality to which you belong, your race or physical characteristics, all human beings feel comfortable within a narrow range of environmental parameters. Personal factors (for example, health), air temperature, mean temperature in radians, air speed and movement, relative humidity, clothing, and activity level all influence human comfort.
Studies have shown that humans are comfortable only on the inside;
- The temperature range is 23.5 to 25.5 0 C at an air speed of 0.18 m / s in summer and 21% to 23% 0 C at an air speed of 0.15 m / s in winter.
- Humidity range 30% to 60%
In extreme conditions, complications such as hypothermia, frostbite can lead to the loss of a limb or even death. Similarly, extremely high temperatures can lead to dehydration and heart malfunction that can even lead to death. Low humidity can cause dehydration and high humidity will cause a lack of body heat transfer, which can also be fatal in extreme cases. Lack of concentration, drop in efficiency, etc. it is characteristic of high body temperatures.
Indoor comfort environment
Only heating or air conditioning accompanied by humidification or dehumidification can maintain the required indoor comfort conditions. Heating makes up about 60% of your annual energy bill, while the share of air conditioning (which uses only electrical power) is roughly the same as well.
Indoor air quality
In matters of home health, indoor air quality (IAQ) plays a very important role. Today more than ever people are concerned about their health. Home or indoors is where you spend most of your day and what you breathe in, if not clean, will lead to numerous health problems. Unlike in the past, densely populated urban regions with their smog, chemical fumes, smoke, dust, pollen, microbes, toxic gas emissions, etc., make both indoors and outdoors a very unsafe environment. While we can’t do much about outdoor air quality as individuals, indoor quality is completely within our grasp when it comes to pollution control. Ironically, it has been observed that the air inside buildings is many times more polluted than outside.
The way to tackle this problem is better ventilation (or dilution) with less polluted outside air using forced air circulation. Air movement and speed will depend on the design of the ventilation system. Obviously, when you want fresh air in, some of the air inside the house has to be expelled. Along with the expelled air, the thermal energy used to heat the interior (in colder seasons) or cool the interior (in warmer seasons) is lost. Although the use of heat recovery or enthalpy recovery fans solves this problem well, inevitably a small amount of energy is also wasted. To filter polluting particles and odors, the ventilation system must incorporate high-efficiency filters (HEPA) and activated carbon filters (which also increase the energy consumed).
In conclusion, a healthier place to live is energy efficient homes, that is, a home where energy is better managed. Therefore, optimizing energy use and minimizing waste must precede all other actions.
