"The CLIMAWIN consortium, a group of European SME manufacturers and suppliers of windows and ventilation systems, aims to address a major market opportunity regarding energy efficient fenestration systems for renovation of residential and commercial buildings. Specifically, the consortium aims at developing a novel high performance window with electronic operation of an auto-regulated natural ventilation system and electronic insulating night blind powered by solar power. Through in-situ smart sensors and Radio Frequency Based Technology (RFBT), the system will optimize, in real time, indoor climate on the basis of parameters such as indoor/outdoor temperature, CO2 and humidity etc., thereby providing both better indoor climate and reducing thermal loss. The envisaged solution is expected to promote a paradigm shift for building renovation in the construction industry from expensive and energy intensive heating/cooling systems to cost, health, and energy efficient intelligent windows. The climawin project is primarily aimed at the renovation sector, especially in old buildings which do not have energy efficient ventilation systems. The climawin windows optimize both, indoor air quality while at the same time maximizing thermal efficiency in buildings. The proposed demonstration activity includes the installation of Climawin windows at 7 locations in 6 countries and monitoring of their performance over 12 to 18 months; identification of the route to market and development of an associated business plan, the creation of a suite of strong marketing tools including a cost-benefit model to demonstrate long term cost savings and documentation of the manufacturing process and associated costs with a view to exploring licensing of the technology to local manufacturers throughout Europe."
