Periodic Report Summary 2 - MEM4WIN (Ultra thin glass membranes for advanced, adjustable and affordable quadruple glazing windows for zero-energy buildings)

Project Context and Objectives:
Buildings are responsible for 40% of energy consumption and 36% of EU CO2 emissions. According to the Energy Efficiency Plan of the European Commission, the largest cost-effective energy saving potential lies in buildings. Directive 2010/31/EU on the Energy Performance of Buildings (EPBD) foresees that Member States should draw up national plans for increasing the number of nearly zero-energy buildings and the Commissions’ Lead Market Initiative “Sustainable Construction” aims at the development and growth of the sustainable construction market.

Windows are critical elements to control the energy performance of buildings especially for zero-energy buildings. It is of paramount importance to develop windows which show reduced U-value, weight and costs and certain features to control and harvest energy. Such a window will have a high impact in the window industry and will reduce greenhouse gas emissions as long as the window is affordable, can be used for residential and office buildings in every climate zone, for new constructions or in retrofitting of older buildings.

Therefore,

(1) MEM4WIN will introduce a novel IG-Unit for quadruple glazing containing ultra thin glass membranes dedicated as frameless openable windows for direct application in facades. Due to this approach U-values of 0.3 W/m²K can be achieved reducing weight by more than 50% and costs by 20%.

(2) MEM4WIN will implement ink-jet printed organic photovoltaics (OPVs) and fully integrated solar thermal collectors for energy harvesting and micro mirrors for energy control and advances day lighting.

(3) Fabrication costs will further be reduced by replacing conventional and cost intensive materials used for contacts like ITO and silver by graphene. MEM4WIN will introduce production methods like roll-to-plate and ink-jet printing to fabricate contacts for OPVs.

Project Results:
Following work has been performed since the beginning of the project:

Development of a process and optimization of required equipment for the manufacturing of:

(1) tempered ultra-thin glass membranes (reached thickness so far: 1.3 mm)

(2) anti-reflective (AR) coating (reached transmission so far: plus 3%)

(3) quadruple insulated glass unit (reached Ug value so far: 0.3 W/m²K)

(4) frame-less, openable window for application in facades

(5) CVD Graphene for direct transferred transparent contacts

(6) LPE Graphene ink for direct printed transparent contacts

(7) OPV ink for direct printed organic photovoltaic cells

(8) novel lamination techniques for fabrication of OPV glass-glass modules lamination of OLED glass-glass modules

(9) micro mirror arrays for control of solar radiation and light guidance

(10) solar-thermal collector (fully integrated in IG-unit)

Potential Impact:
Expected final results and their impacts:

At the end of the project the aforementioned modular components like micro mirror arrays, OPV, solar thermal collector as well as organic light emitting diodes (OLEDs) will be integrated into a fully functional demonstrator showing the suitability of the used equipment, processes and new materials developed which have following potential impacts:

(1) 50% weight reduction by using ultra thin glass membranes

(2) 50% heat loss reduction by introduction of quadruple IG-unit (envisaged Ug-value: 0.3 W/m²K)

(3) 20% cost reduction (compared to a conventional window with the same functionalities) by advanced fabrication technologies and replacement of cost intensive materials

(4) modular solutions for energy harvesting with smart window: (a) in-line printed Organic Photovoltaic (OPV) for power generation; (b) fully integrated solar-thermal collector for warm water supply

(5) modular solution for control of solar radiation and light guidance with switchable micro-mirrors (envisaged range of transmission between 75% and 2%)
