HyWin
HyWin – the clima tech facade – is a compact double skin glass facade, with integrated sunshield, cooling and heating functions. It allows for sustainable, resilient and smart room conditioning for highly comfortable and flexible room use.

CLIMA TECH FACADE
HYWIN IS THE SOLUTION FOR YOUR SUSTAINABLE AND COMFORTABLE GLASS FACADE.
High rise glass buildings, symbol of progress and elegance, are dominant elements of modern commercial and institutional buildings as well as urban residential concepts worldwide.
We developed a clima tech facade that solves the technical problems of today’s glass buildings, improves their insufficient comfort and at the same time provides a sustainable solution. HyWin is particularly effective in combination with renewable energy solutions, such as geothermal probes and heat pumps. The energy gained from cooling in summer could be used for heating in winter.
With financial support from the Swiss Climate Foundation we have designed and operated a HyWin test unit since August 2020. Based on the data gathered from this test unit we have substantially developed the HyWin facade. Currently, we are realizing a reference building using the HyWin facade for GT Hub in southern Germany.

PHYSICS, COMFORT & ENERGY SAVING
PRINCIPLE
The principle of HyWin is based on controlling the room temperature by means of the temperature in the cavity of the double skin facade. The cavity box consists of a triple insulating glazing on the outside and a simple safety glazing on the room side of the facade. A third glass panel inside the cavity separates the upstream from downstream air flow.
A compact air-to-water heat exchanger in the bottom of the HyWin module and the vertical air flow induzed by a tangential fan adjusts the temperature inside the cavity according to actual sun radiation, internal heat sources and outside temperature. The components are thereby controlled by a decentralized smart control unit depending on the situation.
The closed cavity isolates the room from the outside climate and allows for slow, dustfree air exchange between the room and HyWin module. At the same time, there is a controlled heating or cooling of the room by the HyWin module. The solar energy gathered from the HyWin facade could be stored in seasonal storage, for example in geothermal probes, and be used to heat in cold periods.
In warm periods
The fan moves the air through the heat exchanger, where it cools down. The cooled air flows upwards on the room side of the HyWin cavity extraxting heat from the room in a controlled manner in order to cool the room. This operating mode is used in summer and on sunny days in spring and autumn.
In cold periods
Same principle as the operation in warm periods, except that the heat exchanger heats the air flowing upwards on the room side of the HyWin cavity. The room is heated via a controlled heat transfer to the room. This operating mode is used in winter and on cold days in spring and autumn.
SYSTEM BENEFITS
- HyWin solves the actual problem of cold radiation from the window in winter and warm radiation in summer. The room climate remains comfortable right up to the vicinity of the window in hot and cold periods.
- Reducing the temperature in the cavity below room level results in soft room cooling. Increasing the temperature in the cavity above room level provides for mild room heating. Both operating modes are controlled by a decentralized control unit with maximum comfort and energy efficiency.
- Volatile conditions require flexible room utilization concepts – HyWin adapts efficiently to changing types of use as well as changing room layouts.
- HyWin is sustainable. It offers an outstanding energy balance of a building or an area superstructure. Low flow temperatures using renewable energies are possible by design. The considerable energy collected from the HyWin facade could be utilized to regenerate geothermal probes and consumed it for heating in cold periods.
- There is no deterioration or damage to the sun blinds, thanks to the moderate and rather constant temperatures in the cavity and the absence of the aggressive dried air.
- Realizing buildings with HyWin allows for a reduction in investment and operating costs. The HyWin system is cost efficient by using components proven for years, requires low maintenance and is long lasting.
- Due to the modular prefabrication, HyWin reduces construction times and increases the quality of the construction work.
- The intelligent integration of the façade and technical building equipment increases the net floor area and the enclosed space.
We have developed, tested and patented the HyWin system. Currently, we are realizing a reference building in southern Germany.
HyWin is ready to revolutionize glass facades.
