InDeWaG - Industrial Development of Water Flow Glazing Systems
InDeWaG

OBJECTIVES / VISION

The main objective of InDeWaG is to develop an industrial technology for fabrication of cost affordable general-purpose Fluid Flow Glazing façade elements, which give maximum daylight utilization and maximum interior comfort at energy consumption level of nZEB. In addition, also interior radiant elements will be developed. This technical development is accompanied by the development of an open access software tool for design of buildings with this new type of façade and interior radiant cooling and heating elements.

The cost reduction of at least 15% is achieved by following the LowExergy9 principle and adjustment of the temperature difference between the exterior environment and the interior to a minimum value which is relevant for significant reduction of HVAC energy demand and lighting energy consumption.

European Commission - Horizon 2020

The Horizon 2020 Energy Challenge is designed to support the transition to a secure, clean and efficient energy system for Europe. The Work Programme 'Secure, clean and efficient energy' is split into three focus areas: Energy-efficiency; Low carbon technologies; and Smart Cities & Communities.

The total budget for the Energy Efficiency call amounts to approximately €100 million for 2014 and a further €100 million for 2015.

Under the EU framework programme Horizon 2020, a contractual Public Private Partnership on Energy-efficient Buildings sets to develop affordable breakthrough technologies and solutions at building and district scale, facilitating the road towards future smart cities. High-tech building industry will turn energy efficiency into a sustainable business. Research and innovation priorities are disseminated among stakeholders across Europe and aim at deliver technologies for a new sustainable and competitive European construction industry.

DESCRIPTION





InDeWaG is an acronym of the project "Industrial Development of Water Flow Glazing Systems". The Water Flow Glazing (WFG) technology is a transparent façade consisting of glazings with circulating water inside. The system developed within the InDeWaG project uses water-glycol mixture in the chamber between the glass planes to capture the solar radiation and utilize it for different purposes such as heating, preheating and domestic hot water. Another option, which WFG provides is cooling, achieved by dissipation of the absorbed heat.

The InDeWaG project has assembled a multidisciplinary consortium consisting of large industry, SMEs, research organizations and universities. The team is based on 10 full partners from three different European countries - Germany, Bulgaria and Spain. All partners work together to achieve the project objectives. The project work plan is organized in 8 technical Work Packages (WPs) and one administrative WP. Each WP is coordinated by a WP-Leader responsible for effective execution of the tasks and for achieving the main goals.
