As part of a series of IEA Roadmaps on energy technologies, this report specifically maps the potential development of heating and cooling equipment for energy-efficient buildings between 2011 and 2050. In line with other roadmaps, two scenarios are plotted: a baseline scenario representing minimal policy change and a BLUE map scenario with aggressive policy action.
Advanced solar thermal technology will major role to play in reducing CO2 emissions under the report’s BLUE map scenario. It plots that solar thermal technology will account for 11% of total energy consumption in the building sector by 2050, and account for 29% of total CO2 savings. In total, 1.2 gigatonnes (Gt) could be saved in 2050. This progress will be possible because of market transformations taking technology from small-scale employment to large-scale technologies.
The report makes clear that broad and deep policies combined with strong R+D support are necessary to stimulate such development. Standardised information packs should be developed and education of key professionals improved; along with the introduction of mandatory quality assurance and certification schemes for equipment and institutions. With such changes in effect, installed cost levels could decrease by between 50 and 75% by 2030.
