The term "building a gree n economy" may come across as the vacuous creation of a political spin doctor somewhere, but for many companies the sound of cash pouring into their coffers as a result of work in this field has anything but a hollow ring.

One of them is Danfoss of Denmark, which makes, among other things, energy control devices. Danfoss, which celebrated its 80th birthday last year, now operates in 18 countries and has 56 factories. It has four major business lines: green building, cold chains, hot chains and district energy. It had revenue of about 33.6 billion Danish krone ($6.2 billion) worldwide last year and employed 23,000 people.

The company set up shop in China in 1996 and has invested 1 billion yuan ($161 million) in the market. It has two industrial campuses, one in Wuqing, Tianjian, and another in Haiyan, Zhejiang province, and a standalone factory in Anshan, Liaoning province.

Danfoss has had a presence in China since the 1950s when it supplied the compressor for the then popular refrigerator brand Snowflake.

As a business-to-business company, Danfoss's brand name is barely seen by the public at large because it is hidden inside the cases of home appliance s or in the plant and machinery of huge factories, in the same way that Intel chips are locked inside computers.

To illustrate one of Danfoss' practical applications, Christian Overgaard, president of Danfoss China, talks of home heating. During winter in one building some radiators may be so hot that windows needed to be open to let in cold air while elsewhere in the building it is so cold that people have to buy electrical heaters to keep warm.

"As a result of this uneven heating, 15 to 30 percent of energy is wasted," Overgaard says. "Actually, this can be easily addressed by adding a thermostat valve on the radiator. By adding such a small component that costs only five to six yuan every square meter, energy consumption can be cut by 15 to 30 percent."

Industrial research shows that in China energy consumption in buildings accounts for 30 percent of the total, of which 60 percent is used in heating.

The thermostat valve was invented by the founder of Danfoss, Mads Clausen, in 1943 and gradually became a must-install component in Europe an countries, Overgaard says. Now it can be seen in the Empire State Building in New York, Red Square in Moscow and the Great Hall of the People in Beijing , he says.

Urbanization in China will bring big opportunities to Danfoss, he says.

"The urbanization rate in China last year was 54 percent. Sociologists predict it will reach 70 percent in a few decades. This means more people will live in a certain space, and we need to help them live comfortably and environmentally."

The Ministry of Housing and Urban-Rural Development says that with rapid urbanization China will add another 30 billion square meters of living and working space over the next three years, which will put a huge strain on energy supply.

Last year China became Danfoss' third-largest market, after the US and Germany, contributing about 10 percent of its global revenue. "The BRICS' contribution has risen from 9 percent in 2003 to 2013's 22 percent and China makes half of it," Overgaard says. "I think China will overtake the US and Germany in the next 10 years."

Cold chains, especially smart refrigerating systems, are another important area of growth for Danfoss China. Its customers are mainly refrigeration companies and supermarkets, including Walmart Stores Inc, Carrefour Group, Air China catering center and the national blood center in Chongqing.

"The systems are designed to keep the products fresh, but usually it is a waste of money and energy because the system is designed for the worst scenario, which doesn't happen frequently in daily operation."

For example, some marine products should be kept at very low temperatures. To keep all products fresh, managers usually set all fridges to the lowest temperature.

"The electricity bill in a supermarket is usually very high," Overgaard says. "A large-scale supermarket can easily get a bill of 2 million yuan at the end of the year, which almost equals the annual profit."

By using a smart refrigerating system to adjust temperature automatically, electricity bills can be cut 10 percent, he says.

Danfoss is also closely working with local governments to optimize energy allocation. During then president Hu Jintao's state visit to Denmark in 2012, the two parties signed a series of agreements to cooperate on energy projects, of which the biggest is a contract between Danfoss and the government of Anshan, Liaoning province.

Under the agreement, Danfoss is to make a 400 million yuan local heating network in Anshan. It replaced old boilers with larger ones and connected them to a local steel plant that has been constantly generating heat. The heat can meet the needs of 1 million people.

Previously the heat had simply been dumped but is now used as an inexpensive, efficient means of warming households, the company says. Because the heat was traditionally generated by burning coal, this initiative can also cut carbon dioxide emissions by 240,000 tons a year.

Xinhua News Agency quoted Karsten Dybvad, CEO of the Confederation of Danish Industry, as saying: "I believe more sustainable growth in China can turn out to be an advantage to Danish companies because of the technologies and solutions we have developed in our effort to create a green economy."
