Better shelter

The house with no heating system

By 2020 all new buildings must be nearly zero-energy buildings

Chlorine chemistry is used in the manufacture of integral parts of high energy performance buildings. These include renewable onsite energy sources such as solar panels, and high insulation performance triple-glazed windows.

These so-called zero-energy buildings require most of the very small amount of energy they use to be provided from renewable sources, produced onsite, for example solar energy. The vast majority of today’s solar panels are made up of a series of high-purity silicon solar cells. High purity silicon is produced by heating hydrochloric acid and a compound called trichlorosilane together to temperatures above 1000⁰C.

Another energy saving measure than can be incorporated into zero-heating-cost houses is triple glazed heat-reflecting windows made with specially coated window panes that are held together with polyvinylchloride (PVC) frames. The triple-glazed windows are filled with an inert gas with better insulating performance than air.

Other features of zero-energy housing include highly-efficient insulation materials and ventilation systems that maximize heat recovery. Even human body heat is efficiently used.

The EU Energy Performance of Buildings Directive (Directive 2010/31/EU) requires that by 2020 all new buildings must be nearly zero-energy buildings.
