We leave his office, walk over to one of the tallest buildings at the hospital, and take the stairs past the Cardiac Department on the first floor and the M2 Medical Department on the second. On the third floor Stig gets out a ladder, so that we can climb up the windowsill and out onto the roof. And here is the 280 sq. m. installation. The individual panels, which look like tinted windows, are connected to pipes which bring cold water into the panel system, where it is warmed and passed on to provide hot water for patients and staff. "On an annual basis, the system provides about 15 percent of the hospital's hot household water, but on days when the sun is shining, this rises to almost 100 percent," says Stig Toftebjerg. gReat potential Even though it can be expensive to install a solar thermal plant, it is a good investment. It pays for itself within 10-15 years, and after that the hot water is free. Moreover, the environment benefits from day one. Stig Tofteberg hopes however that in time the installation will contribute even more to both the hospital's finances and the environment. Today, much of the heat goes to waste, especially in summer, when the sun shines most, but there is less need for heating.

It takes time
he cooling equipment howls like an endless siren. Beneath the ceiling of the murky basement room hangs a tangle of cables in all kinds of colours. At one end of the room, grey pipes transport warm water from the solar thermal installation on the roof. "It was exciting at the start when we were working to get the system to run properly, but now I don't spend so much time on it," says Johnny Carlsen of the Technical Department of Silkeborg Regional Hospital. On the other hand, he certainly spent time on the system during its first year of operations. "Don't think that you can just set up some solar thermal collectors and let them look after themselves,"
T
says the hospital's technical manager, Stig Tofteberg. It took a long time to adjust the system so that the amount of water going through matched its pumping speed, because the more the sun shines, the faster the water heats up, and vice versa. Today, however, Johnny Carlsen has complete control of things. On a laptop, he showed me the difference it has made, with the help of some column diagrams. "As you can see, at first we didn't make very efficient use of the sun, but with some technical changes and daily adjustments that has changed, so now we're close to one hundred percent," he says.
