Hackney private residence

The owner with his architect wanted to create an environmentally friendly house in London's East End.

Contract Value: Not Disclosed
Date: 2009
Local Authority: Hackney, London


This was an architect-led project on a Grade I listed building situated in a large Edwardian grand terrace in Hackney.


To design an environmentally friendly house, using natural ventilation instead of air conditioning to keep energy consumption low, within a conservation area for the client and his young family.

The building had a low ceiling and limited floor space, which had to accommodate the engineering services. Several designs were explored to find the one most suitable to fit the property.


Consolux M&E Consulting examined renewable resources for building to help identify technology that could be successfully integrated into the property during the early stages of design. We completed this with reference to the Chartered Institution for Building Services Engineers’ (CIBSE) TM38 sustainability guide.

We developed a scheme that included a rain water recovery system for use in flushing toilets. Gas powered combined heat and power (CHP) was used to maximise energy efficiency for space heating and hot water. CHP is the method of capturing waste heat from power generation to create useable energy. Solar panels were also used to generate energy for the hot water.

To resolve the problem of sourcing natural ventilation instead of using air conditioning, the property was extended at the rear to create a double height, large glass wall area.

Consolux provided advice on improving the insulation within the building and, together with the architect, devised a method of internally lining the brick walls with insulation. Low emissivity (low E) glazing was also used on the windows to optimise the reduction in the amount of energy needed to heat the property, saving the owner money on energy bills and reducing the CO2. emmissions.

We also specified absence movement sensors to regulate lighting - lights are activated when the sensors detect a person’s movement and automatically switch off after a pre-determined time once a room becomes empty.

Photo-voltaic panels and wind turbines for electricity generation were rejected on the grounds of cost and economic payback.
