Thermal insulation is an important technology to reduce energy consumption in buildings by preventing heat gain/loss through the building envelope. Thermal insulation is a construction material with low thermal conductivity, often less than 0.1W/mK. These materials have no other purpose than to save energy and protect and provide comfort to occupants. Of the many forms, shapes and applications of thermal insulation, this section focuses on those that are commonly used for building envelopes– i.e., floor, walls and roof, and have potential for South-South technology transfer.

WECF is an international network of over 150 women's and civil society organizations implementing projects in 50 countries and advocating globally to shape a just and sustainable world

IIGE is a research institute that promotes development, innovation and transmission of technology focused on energy efficiency and renewable energy. The institute aims to contribute to the sustainable development of the Ecuadorian society, through the implementation of energy efficient and energy renewable policies and projects.

The Global Environment Centre Foundation (GEC) is an entity that supports the UNEP’s International Environmental Technology Centre (IETC), based in Japan. GEC is dedicated to the transfer of environmentally sound technologies, in both developing countries and countries with economies in transition. The foundation aims to contribute to Japan’s international efforts on the environment, sharing project collaborations as well as promoting Japan’s rich conservation knowledge and experience in developing nations.

This invention provides an energy-efficient cost-effective and aesthetically pleasing water storage façade system for buildings with heat penetration reduction and heat storage capability. Firstly it can achieve energy savings for air-conditioning in buildings by using water as thermal insulation medium in building façades and harnessing the thermal energy absorbed and stored by water to reduce heat penetration due to the Sun’s Solar Radiation falling onto building façade walls.

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing methods for producing aerogels that contain nanoscale cellulose fibers and are suitable for an array of applications.

In China, the market for extruded polystyrene (XPS) foam used in building insulation increased the last years at double digit growth rates due to the fast rise of the economy and the associated construction boom. This growth in the market for insulation is brought about by new regulations on building insulation as part of the Chinese energy efficiency programme.

GIZ (former GTZ) Proklima has compiled this publication to provide information on natural foam blowing agents as ozone- and climate-friendly alternatives to HCFCs. The first section of the book covers policy-related aspects of technology transition towards natural foam blowing agents and examines the impact legislative changes have on development and adoption of alternative technologies. The second part deals with the use of natural blowing agents in rigid and XPS foam, the conditions for conversion and special technologies. Part 3 comprises case studies from developing countries.
