Not being able to heat a room above 16°C is a better problem to have than not being able to cool below 30°C but cold takes it's tool too. At night you can use a thick comforter or a couple and the problem is solved, but working behind a desk in a cold room is trying. Many layers of closing helps but it is not an ultimate answer - while being in a cold room in warm clothing I become tired more quickly than in a room at 20°C—25°C.
