Opposite the City Hall, 3 new building are under construction: a congress hall, a hotel and an office building. The project, known as Stockholm Water Front commenced in 2005, when the City of Stockholm decided to build a new conference centre with a hotel facility. But an office building was also built. in order to finance its realization. Stockholm Water Front aims to achieve environmental excellence. There are three installations, which make this possible:
<em>Glass Facades are giant solar collectors</em>
The large glass facade of the Congress Hall is perfectly located in the southern direction and acts as a giant solar collector. Already in the beginning of March, it is possible to extract 1 MW of energy. The façade has double layers of glass with air between them, which is heated by the sun. The hot air is converted to hot water and distributed to other buildings, for heating domestic water.
<em>Energy in balance</em>
Stockholm Water Front consists of three buildings with totally different energy profiles. The office building does not use much energy during evenings and nights and the hotel has its highest energy consumption during mornings and evenings. This imbalance is used whereby energy is transferred between the buildings according to the demand. In order to produce cooling, Stockholm Water Front uses a method, called phase transformation, which means that the cooling is stored in ice during the night. Plain water is extremely effective in storing cold. In addition one will also use cold water from the nearby Klara Lake.
Stored heat makes football pitch playable

Hörneborgsverket produce roughly three equal amounts of district heating, steam, and electricity. The steam is distributed to the neighbouring process industries – Domsjö Fabriker, AkzoNobel and SEKAB. Due to the industry’s need for steam, which is in demand throughout the entire year, the cogeneration plant is used to a greater extent, in comparison with power plants that only supply district heating, of which the demand fluctuates. A total of 99% of the fuels used at Höreborgsverket are renewable fuels.
