Solar Heating Facades Are Very Commonplace Nowadays

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.

On many roof tops there are large open spaces that are not used these include hotels, hospitals and industrial buildings. On sides of walls as well as the exterior of buildings and garages theses empty spaces can be put to good use. Many of the easier and homemade ones can be erected without the help of a professional.

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.

If more people install the panels more jobs can be created as they will need to be designed, built as well as installed and maintained. For those workers that need to travel distances the companies involved could erect housing with low rates close to the factory also reducing the pollution all vehicles produce daily. Shuttles could also be introduced to ensure that all of the employees make it to work on time so more time is spent at work.

One very good idea that ensured heat was distributed into a building was by the Revered Poole and two of the members of his congregation. They used both beer and soda cans cut in half which reduced their fuel cost by over fifty percent. The plan was drawn up over a weekend and was put into practise on a sunny afternoon. The inside temperature reached ninety five degrees Celsius and the council then decided to fund two more of these units.

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 like all other systems can also be damaged by hail, large stones and by birds. They can be difficult and dangerous when needed to be replaced but many see this as something that may not even be needed to be done for many years. If one panel develops a problem the rest of the system will still run normally. Each system usually has about twenty panels and with one out of commission it will still run at ninety five percent of its accepted performance.
