A Healthy Place to Live –Role of EnergyAuthor: John Mahoney
Health and Indoor Conditions
If a home is energy efficient it will be a healthier place to live in too. The fact is your home energy is utilized mainly for maintaining a comfortable environment where the Temperature, Humidity, and Air quality is well regulated. Energy also provides a drive force for a hygienic modern life style where every device and appliance used makes use of energy for achieving the desired out put.
If energy is used almost in every aspect of running the home unless it is managed properly your hard earnings will simply seep out of your house.
Comfort conditions Irrespective of the geographical location of your country, the nationality you belong to, your race or physical features all human beings experience comfort within a narrow band of environmental parameters. Personal factors (e.g. health), Air temperature, Mean Radian Temperature, Air movement and velocity, Relative Humidity, Clothing and activity level all influence human sense of comfort.
Studies have shown humans feel comfortable only within;
- The temperature range of 23.5 to 25.5 0 C at an air velocity of 0.18m/s in the summer and 21% to 23% 0 C at an air velocity of 0.15 m/s in the winter.
- Humidity range of 30% to 60%
In extreme conditions complications such as hypothermia, frost bite may result in lost limb or even death. Similarly extreme high temperature may lead to dehydration and heart malfunction leading even to death. Low humidity may cause dehydration and high humidity will cause lack of body heat transfer which too may be fatal in extreme cases. A lack of concentration, drop in efficiency etc. 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 constitute about 60% of your annual energy bill while Air conditioning (which uses electrical energy only) share too is about the same.
Indoor Air Quality
In home health issues Indoor Air Quality (IAQ) plays a very big part. Today more than ever people are concerned about their health. Home or indoors are where you spend most of the time of the day and what you breathe in if not clean will lead to numerous health problems. Unlike in the past the thickly populated urban regions with its smog, chemical fumes, smoke, dust , pollen, microbes, toxic gas emissions etc makes indoor as well as out door a very unsafe environment. While we cannot do much with regard to Out Door air quality as individuals, indoor quality is entirely within our purview when it comes to pollution control. Ironically it has been observed that indoor air of buildings is many times more polluted than the out doors.
The way to tackle this issue is better ventilation (or dilution) with less polluted out door air using forced air circulation. Air movement and velocity will depend on the design of the ventilation system. Obviously when you want fresh air to come in, part of the air within the house has to be forced out. Along with the air expelled thermal energy used to heat the indoors (in colder seasons) or cool the indoors (in hot seasons) is lost. While the use of heat recovery or enthalpy recovery ventilators addresses this problem well inevitably a minute amount of energy too is wasted. To filter out particulate pollutants and odors the ventilation system need to incorporate High Efficiency ( HEPA ) Filters and activated carbon filters (which too increase the energy consumed).
In conclusion a healthier place to live in is energy efficient homes i.e. a home where energy is managed better. Optimizing energy usage and minimizing wastage therefore must precede all other actions.About the Author:

Community: Energy Efficient Homes
Most people are concerned with making their money last longer and energy conservation can help by reducing our energy costs. Homeowners can do many things to cut down on their energy needs. Perhaps the best thing they can do to is to install better insulation to retain warm and cool air.
Heating and air conditioning are the biggest energy consumers of the average household. Much of the heat and cool air escapes because of poorly insulated roofs, walls, doors, and windows. In fact in a lot of cases heating and cooling is responsible for around 50% of your energy costs. Improving insulation will result in greater conservation of energy and lesser energy costs. Small changes in this area can result in dramatic reduction in your monthly payment to your utility company.
Old cooling and heating appliances should be replaced with newer models which are more energy efficient. Other large appliances like refrigerators can also be replaced with newer models that are designed to conserve energy. Always make sure you read the energy label, if you do, you will often find that a cheap product in fact can be expensive in its every day use because of its energy consumption.
Traditional light bulbs are inefficient because much of the energy they consume is converted to heat. Replacing all your incandescent bulbs with compact florescent bulbs will provide the same level at light with less energy consumption. Even though the cost of these bulbs is greater than traditional bulbs, they last up to 20 times longer, resulting in significant overall savings.
Using alternative energy sources such as solar panels or wind turbines can greatly reduce the amount of energy needed from traditional sources. The electricity produced by these devices can be fed back into the local power grid if it is not immediately used by the household. This reduces the power bill even further (the power meter runs backwards) while supplying clean power to your community.
Conservation of energy is not just for homes, cars and trucks are available with more energy efficient engines and some can run on alternate power sources such as hydrogen or electricity.
Conservation of energy is something that everyone can contribute to. By being careful in how we use our resources we are building a society for our children and grandchildren.
