The WEO 2009 sets out a timetable of actions needed to limit the long-term concentration of greenhouse gases in the atmosphere to 450 parts per million of carbon-dioxide equivalent and to keep the global temperature rise to around 2 ° Celsius. Alongside its sombre warning that every year of delay in implementing these measures adds $500 billion to the energy sector’s mitigation costs, the IEA highlights there are cost-effective solutions to avoid severe climate change, while also enhancing energy security.

A Bus Rapid Transit (BRT) system in Mexico has shown that green solutions have strong potential to increase comfort and quality in life - important considerations for fast-growing, emerging economies. China's programme of targets for the 1000 most energy intensive enterprises led to permanent improvements in energy management and efficiencies in these companies.
The WWF-World Wide Fund for Nature urges the G20 Finance Ministers to take the steps required now to ensure that the next major wave of infrastructure investment is green.

Existing techniques and technologies in energy efficiency retrofitting can reduce energy use by up to 40 percent per home and lower total associated greenhouse gas emissions by up to 160 million metric tons annually. Retrofitting existing homes also has the potential to cut home energy bills by $21 billion annually. Yet, despite the real energy cost savings and environmental benefits associated with improving home energy efficiency, a series of barriers have prevented a self-sustaining retrofit market from forming.

The German SurPlusHouse includes photovoltaic on all walls (also on the north side as a system was chosen that can produce electricity from diffuse radiation as well) and a heat pump for heating, domestic hot water and cooling. The building is very compact and results therefore and because of the vacuum insulation in very low transmission losses.

The conference was organised by the Air Infiltration and Ventilation Centre of the International Energy Agency together with Energie- und Umweltzentrum am Deister (E-U-Z) and the Fraunhofer Institute for Building Physics. In parallel to the AIVC conference the international symposium on "Airtightness of Buildings and Ductworks" took place accompanied by an exhibition of industry developments in this field. The conference papers will be offered soon for download on the AIVC website (http://www.aivc.org/).
