Architectural scientists and technologists are seriously engaged in the study of an effective solar heat collector for zero-carbon and zero-energy buildings.

The high-efficiency trial solar heat collector is capable of simultaneously producing electricity and heat. The researchers now focus on boosting its function.

Some units work hard to study and develop not only green building-materials but also insulating material, block and board, etc. from waste and by-products, making a series of achievements.

Progress is being made in the research into the recycling of urban and industrial waste.

Building-material additives and building parts necessary for rooftop gardening have been introduced to various projects.

For trees transplanted all seasons for the protection of the forest ecological environment, chemicals for increasing their rooting rate has been successfully developed and applied, paying off in practice.
