ChromoGenics solves the dilemma of air conditioning

The climate on earth is getting warmer, which increases the need for air conditioning in buildings. However, the cold that the world’s energy-intensive air-conditioning systems produce lead to further warming of our planet. Thus, global warming is leading to people’s increased need for products that aggravate the original problem, writes Stephen Buranyi in a report in The Guardian. ChromoGenic’s technology solves the dilemma.

With an increasingly warmer climate, the number of air-conditioning systems will increase from just over one billion to as much as 4.5 billion by 2050, according to several reports. During a heat wave in Beijing 2018, as much as 50 percent of all electricity went to air conditioning, says John Dulac of the International Energy Council, IEA.

By 2025, according to IEA calculations, as much as 13 percent of the world’s annual electricity production could go to air conditioning, which would simultaneously produce two billion tonnes of carbon dioxide per year. This corresponds to the emission level in India, which currently has the third highest emission levels in the world.

An increased use of air conditioning equipment would thus lead to a huge increase in energy consumption and carbon dioxide emissions in the world. How can we get out of the air conditioning trap? asks Stephen Buranyi in The Guardian.

ChromoGenics has the solution and it drastically reduces the need for air conditioning, in some cases even completely. The technology in our smart glasses stops solar heat before it even enters the building. Our combination of dynamic and static glass technology offers windows with sunblock up to 90% with free access to daylight and views.

Our dynamic solution adjusts the solar transmittance depending on conditions such as time of day, outdoor temperature and window position. The effect is that the window block the solar heat when it is warm and let the solar heat in when it is cold, in order to regulate the indoor comfort.

We have developed an electrochromic foil that has revolutionized the dynamic glass market. The foil is supplied as laminated glass or insulating glass with two, three or four glasses. An electronic control unit automatically regulates the tone of the film and the solar transmission, for example by connecting to a sensor network. By applying a low electrical voltage to the electrochromic foil, the solar transmittance and tone are controlled discretely.

Since the foil only uses electricity during the time when the tone changes, it is very energy efficient. We also offer fully self-sustaining dynamic glass, powered by integrated solar cells. We have the environment in mind during the entire life cycle of the product and an environmental product declaration published, where the environmental impact of the product is declared.

We are not the only ones with strong faith in the potential of electrochromic materials. Stephen Selkowitz, a well-known scientist in building science at Lawrence Berkeley National Laboratory in the United States, sees electrochromic film and glass as the most promising technology for variable energy control in buildings.

The sun is the creator of our climate. ChromoGenics is the creator of high-performance facade glass in collaboration with the climate. Welcome to more light, smarter sunblock and lower energy costs. Welcome to a more sustainable future.
