Solar Thermal Market Development in IEA SHC Countries
The solar thermal market in the member countries of the IEA SHC has developed dynamically between 2001 and 2011 (the last year for which IEA SHC has data, as published in Solar Heat Worldwide), from 6.7 GWth to 42.9 GWth or 20% p.a.. The strongest growth was seen in Portugal (36% p.a.) and Canada (31% p.a.), while Sweden was the only country, whose 2011 market was smaller than in 2001 (-1% p.a.).
By far the largest national market in absolute numbers is China, which reached 40.3 million MWth in 2011 and an average annual growth of 21.5% between 2001 and 2011. In the same time its share of the total newly installed solar thermal capacity in IEA SHC countries increased from 85% to 94%.
Solar Buildings Market Development in IEA SHC Countries
Solar buildings are not (yet) a market segment of their own in the IEA SHC member countries. Instead, other low-energy concepts, such as “passive houses”, “energy-neutral” or “net zero energy” buildings are gaining market shares – partly because of environmental concerns, partly because of the cost of conventional energy supply. In most countries, there exist rating or certification schemes, which assess the energy performance of buildings. Some of them are mostly local, such as the Swiss Minergie system, whereas others are internationally used, such as LEED or BREEAM. Within these concepts, active as well as passive solar technologies are usually considered, i.e. the installation of a solar thermal water/space heating system improves the overall energy efficiency of the building and thus helps achieve a better rating.
In commercial buildings, daylighting is more and more used to replace electrical lighting and to contribute to higher comfort.
