Lack of space in cities restricts opportunities for outdoor exercise, resulting in city-dwellers wasting energy on journeying to the outskirts in search of open areas. The energy saving solution to the problem is close by, however. Rooftops are readily available outdoor space that can be used for sporting activities. In central Copenhagen the roof of a multi-storey car park has been transformed into a 2400 square metre adult fitness zone where people can run and work out all day, all year, 24 metres above the ground. The all-weather exercise surface is produced from the granulated remains of old tyres and Nike shoes.

ØsterGro Rooftop Farm in Copenhagen is an example of a growing trend for urban green rooftops. Some cities have even made them part of their sustainability plans
Development of sustainable buildings is moving fast, pushing them to being energy producers rather than energy consumers. One example is UN City in Denmark
A unique engineering project has raised the bar for efficient energy capture from incineration of garbage and provided a sports facility in an urban location
Tough legislation in Denmark has prompted development of highly advanced technology to detect leaks from the water mains
Heavier cloudbursts, rising sea levels, more flooding. This is the outlook for many urban areas. City councils, architects and engineers are responding to the challenges of a wetter future by looking at ways to adapt the urban landscape rather than expanding traditional underground drainage solutions. The approach saves money and creates better urban spaces.
