Energy efficient houses – ZEB zero energy building
Zero-consumption houses are no longer an unattainable goal, but simply an established construction practice and a goal enshrined by European Community member states in Directive 20 20 20 http://ec.europa.eu/energy/en/topics/energy-efficiency
Until recently it seemed impossible to build truly well-insulated houses. in the 1990s a few centimeters of thermal insulation was enough to be up to code, then it went to 10 cm, then 15 cm, and now we envision 20 / 25 cm of insulation a true super-insulation http://www.exligno.it/isolamento/
The recipe is very simple: we use a lot of insulation and use materials that ensure both summer and winter thermal efficiency.
In this way, the house becomes really easy to heat to the point that household appliances alone together with the thermal emission of the inhabitants’ human body are enough to bring the temperature up to comfort levels.
In this way, we avoid tapping into nonrenewable energy sources such as gas and diesel fuel and use the sun as the primary source for self-generation of electricity and heat through photovoltaics and solar thermal ensuring thermal efficiency and zero consumption.
The materials we use to ensure thermal insulation and thus energy efficiency and ‘zero consumption goal are not derived from petroleum but are from mineral sources such as rock wool or plant sources such as wood fiber. This allows for better summer insulation as well as ensuring that our properties are more environmentally friendly.
