The Council House

The Council House

Application: Offices & Public Buildings

The historic Derby Council House has recently undergone a £32 million redevelopment to create an energy-efficient, city centre headquarters for Derby City Council that is fully accessible to the public.

Designed by architects Corstophine and Wright, the redeveloped building still retains its original façade designed by Charles Aslin in 1939, and sets an example as to how historic buildings can be redeveloped to fit with today’s modern requirements. Taking two years to complete, the project included extending the premises to 18,500m² thereby allowing the staff head count to be increased to over 1,900.

With environmental considerations at the forefront of the refurbishment, the Council House is designed to BREEAM ‘Excellent’ standards and has achieved an ‘A +’ rated Energy Performance Certificate. The sustainable strategy deployed includes a hydro-electrical power plant, solar panelling, rainwater harvesting and an adiabatic cooling system.

As part of the development’s energy-efficiency strategy, Jaga supplied and installed a portfolio of energy-efficient heating solutions.

For discreet heating throughout public access areas, EMCOR chose Jaga’s Mini Canal natural trench heating which is available in a range of lengths and depths to suit the internal layout and different depth of floor voids found at The Council House. The Mini Canal, fitted with Jaga’s DNA Designo rigid aluminium grille, also allowed for heating to be installed directly underneath public seating areas – ensuring the comfort of visitors.

In other areas, EMCOR opted for wall-mounted, slim-line Strada radiators, featuring Jaga’s patent Low-H20 technology that has a low-mass, low-water content system. This technology means the Strada responds faster to fluctuations in temperatures, reduces energy costs and consequently supports the overall sustainable strategy of the Council House.

In line with BREEAM’s ‘Excellent’ standards, it was imperative the Council House offices received an upgrade from the previous inefficient, cast-iron radiators. With glass facades used extensively in the development, the building required a solution that could efficiently heat the office spaces whilst still allowing great views through the glazed façade. Jaga’s Mini Freestanding – equipped with special “rosettes” to cover the feet – was chosen for its discreet and attractive appearance and powerful heat output that defies its small dimensions.

With a redesigned, fully accessible Council Chamber visible throughout the building, it was important to install a heating system that not only provides well-distributed heat in a large space, but is a strong, aesthetic statement piece. With slim triangular radiant pipes placed alongside each other in a flat plane, the design team found the ideal solution in Jaga’s award-winning Alpano Plus radiator – which offers high heat output yet is sophisticated in design.
