Spirotech vacuum degassers and dirt separators have been specified for 100 Bishopsgate, a 37-floor office block in the City of London. This mixed-use building, with major pre-lets to major world banks, is being developed by global real estate investor Brookfield. The Spirotech equipment will have a key role to play in maintaining the condition of the water in the building’s heating and cooling systems, helping them to operate to optimum levels.

The thermal mass of new teaching buildings at the University of Northampton’s new £330 million Waterside Campus will play a key role in achieve comfort conditions through the incorporation of Rehau’s TABS (thermally activated building structure) system into the concrete floor slabs. The TABS cooling and heating system uses the large thermal mass of concrete in a building’s structure to adjust the environment inside the building during the day.
