Benefiting from passive solar energy
Passive solar energy is about harnessing solar energy that enters your home through glazed areas, reducing your need for traditional heating systems. To benefit from passive solar you need design a building or refurbishment with that in mind.







The cavity wall dates back to 19th Century Britain, a pioneering method in the construction industry that gained widespread use from the 1920s. They were primarily implemented to prevent the passage of moisture into the interior of the building; preventing damp, other benefits include sound and heat insulation. However, do we need this cavity in an age of high tech materials that can insulate and damp proof our home from the elements?
In a previous article I proclaimed insulation as an Eco-superhero, like most superhero’s insulation needs an effective sidekick. Batman needs robin, like insulation needs draught proofing. The more air tight your home, the more effective your insulation. 
Rainwater harvesting systems require pumps to move stored water to the point of use since the tanks are not under mains pressure. As a result the following questions have become very common among those enquiring about the technology: Does the cost of running the pump negate any savings made? By running a pump, are we increasing our carbon emissions, and negating any environmental benefits?
