Thermal energy (Termoenergi) refers to the amount of power that is needed to raise the temperature of a material, and/or to reduce it. By adding up the specific temperatures required to do the work and subtracting the amount of heat already available, you can determine the thermal energy of a particular material. Thermal energy is used in power systems as well as in many other applications to help with reducing costs and reducing waste.

Thermal energy is one of the main requirements for building construction in all kinds of climates. The basic requirements for building physics are to take into account the rate of absorption and the rate of evaporation. The thermal conductivity and thermal resistance of the different materials have to be taken into account. These two quantities are used to calculate the amount of thermal energy. They are the basis of many decisions that need to be made when choosing materials for a particular application. The relationship between the thermal energy requirements and the climate is very important because the decision to use thermal or photovoltaic energy in an environment may have an impact on the life expectancy of the structure.

The amount of thermal energy in a system is called the thermal resistance of the system. One can calculate the thermal energy requirements of a building by considering the thermal resistance of the roof, the floor, the walls, the windows and skylights. The amount of thermal energy absorbed by the material is called the insulative factor. If the insulation factor is high, then the system will absorb thermal energy easily and will have to have cooling fans to reduce the amount of absorbed thermal energy.

Thermal energy is often used in refrigeration systems where liquid water is involved. Cooling towers are the most common example of a cooling tower. The heated air in the tower is compressed by a cooling fluid. The mechanical properties of the cooled air help to lower the enthalpy of the cooled liquid water.

Another type of energy used to cool the surface of the water is through convective heat transfer. Convection is a process by which heated air is moved from a warmer region to a cooler area. One example of this process is the evaporating of water drops. Thermal energy is used in the manufacturing of heat exchangers and underfloor heating systems. The heat pump is a form of thermal energy where a heat pump boiler heats a fluid (usually water) and moves it through a medium in order to remove heat energy. Air conditioners are also a source of thermal energy where air passes over a heated coil (coil wire) and gets cooled by the passage of an electric current (temperature controller).

The heat in the air is absorbed by objects and moved to cooler places. This transfer of heat takes place when a substance is warm because of its density and because of the energy required to make it that way. One example is the heat energy transferred by the sun from the hot surface of the sun to objects on earth. The energy required is actually thermal or electrical. Cooling can be done in several ways including evaporation, convection, absorption etc.

Thermal energy efficiency is measured in watts per square foot, which is a form of measurement that combines efficiency and cost. Calculating this is usually done by multiplying the annual consumption of heat with the annual production of heat. Once the two values are added, the final value gives the best possible result for a particular product. In order to get a good idea of the level of thermal energy efficiency, many manufacturers take into account several factors when calculating the ratings of their products. Some of these include the design, size, insulation, construction and many other elements.

There are a number of benefits associated with using thermal energy. It is clean, harmless and renewable. In the long run, it costs less and acts as a climate control. It can reduce air conditioning costs, reduce electricity bills, improve home building and increase the value of a property. In short, thermal energy efficiency is gaining a lot of importance these days.
