Post & Echo Building
The Post & Echo Building is located at 95 Old Hall Street in Liverpool city centre, England, and houses the headquarters of the Liverpool Echo and Daily Post newspapers. It is also known as Metropolitan House and as City Tower. The building was completed in 1974, and used as the headquarters of Merseyside County Council. It is a brutalist-style building that stands 73 metres (240 ft) tall with 18 storeys, making it the joint-tenth-tallest building in the city. The upper half of the building is primarily occupied by office space, whilst the lower parts house the newspapers' printing rooms and distribution centre.
Using river water to heat and cool the building
The building was constructed simultaneously with New Hall Place. Both buildings used river water that was at a year round constant temperature of 13C that seeped into the Mersey railway tunnel to heat and cool the buildings, greatly reducing fossil consumption.
