Many Places Are Starting To Sport Solar Heating Facades

By Beryl Dalton


Reducing your carbon footprint has become vital as of late. Many buildings are now in the process of trying to change to solar heating facades. The main goal is to reduce the energy demand. In Europe the New Zero Energy buildings objective is for the future of the planet. Many building that are to be built after 2018 will be of net zero energy.

Some are even going as far as designing coverings for car parks to prevent sun damage. All existing car parks that have side walling and open roof space could also be put to good use. Using this method will increase the lifespan of the vehicle as it will help with the battery life lasting much longer.

All solar powered systems are in demand and can be sold in varying sizes. The bigger systems do need to be installed by professionals and must be serviced regularly but normally they do not give any problems. The upkeep costs of the larger systems per year are about one and a half percent of the invested cost.

The heat grabber is another method that stands just under the window and is quick to assemble and does not cost an arm and a leg. It has a stiff foam insulation board and is impregnated with glass fibres for extra strength. On both sides is heavy aluminium foil ranging from different thicknesses. They are marketed by Celotex. The only disadvantage about this is that the foil can be damaged easily if someone is really out to destroy it.

Each panel has no moving parts and are resistance to many weather conditions. They do not require much cleaning and only sporadic maintenance is needed. They are built to last for up to twenty years and many say that they can be put up and then forgotten about. Sometimes things do go wrong and when this happens they will need to be attended too.

The disadvantages are that they can only be harnessed during daylight and when the sun is shining. Some solar power stations that are built do not match the power output with a similar sized traditional power station. In many countries that have unpredictable climates this could also be a flimsy method of energy and a back up will need to be implemented as well.

The solar water heating system is used by converting the sun's rays into energy. A solar storage tank is mounted above the collector in the roof. There is no pumping required as all hot water rises into the tank by means of thermo siphon flow. During the extreme winter months this might not be sufficient so an electric or gas booster can also be used.

Solar facades will soon be a familiar sight as one walks around town. It will enhance the beauty of the sky reflecting on the panels and will also help to keep the environment free from chemicals. The atmosphere will be much clearer and healthier which in turn will reduce many diseases people suffer from.
