All of you know about the point which is very important in nowadays called as Space heating. Space heating is best of the largest contributors to environmental change created by industrialized countries, creating an faster need for carbon-free heating. Now, the Recent advances adviced or suggest that passive solar energy as a heat source can and should be most important part of a sustainable solution.
Researchers at the University of Oregon, funded by the U.S. National Science Foundation, measured the scale and scope of unused passive solar energy and compared the data to residential space heating needs.
Among the noteworthy findings, the researchers found that cold and cloudy climates are abundant sources of solar energy and estimated that this untapped passive solar energy could provide one-third of residential heating. The group published the research in Renewable and Sustainable Energy Reviews.
The study co-authors Alexandra Rempel said that- "In the course of studying sustainable architecture, it became clear that there were lots of resources we weren't tapping into".
They also said that - "People were dismissing the possibility that there could be enough solar energy available in cold climates." As a result, passive solar heating has been overlooked as a component of sustainable architecture and design.
Passive solar heating process collect pure Or natural light to required heat without converting the light to electricity. In this approach, solar radiation is collected through windows and skylights. Some is used immediately for heat, and some is stored for later use. Capturing, storing and distributing solar energy for heat without converting it to electricity is a feasible option even in cold and cloudy climates, the researchers found.
