Highgate Newtown Estate
client London Borough of Camden
project value £4M
Highgate Newtown is made up of two estates referred to as the Whittington Estate and Dartmouth Park Hill. It comprises 380 dwellings across 19 blocks. Constructed in 1970’s the design of Whittington Estate has become architecturally significant. Architect’s Sidney Cook, Neve Brown and Peter Tabori developed the design and their vision later became known as the ‘Camden Style’ and has since influenced many subsequent developments.
TGA was initially invited to undertake an investigation into the condition of existing distribution installations which formed the communal heating installation. This investigation established that pipework was corroded and that the system lacked control and segregation. Replacement was recommended.
A fifteen month consultation period involving many option appraisals and liaison with residents followed and this resulted in government approval for the replacement scheme.
The new installation involves retention of some major plant components with supplementary plant to increase resilience and efficiency.
A zonal approach is being taken to the distribution installations which will each adopt variable volume control and use heat interface units with plate heat exchangers to decouple the secondary and tertiary installations.
Design features as above will reduce circulation energy and maximise heat transfer to improve the overall efficiency of the installation. Further carbon reduction measures will be incorporated including thermal storage and possibly small scale combined heat and power to generate heat and drive the distribution circuits.
