→ Expected savings of 527 tCO2 a year from deep retrofit

→ Use of smart technologies such as the Greenwich Energy Hero app

→ Saving of 80% in energy consumption

Two social housing estates built in the interwar period underwent a deep energy retrofit. The installation of a Sustainable Energy Management System (SEMS) optimises the estates’ heating and energy system by taking in real time data and
using dynamic energy management to achieve additional cost and carbon savings. At Ernest Dence, the communal gas boilers replaced by a heat pump drawing water from the Thames basin deliver locally generated energy with lower emissions. Smart thermostats, electricity consumption, temperature, humidity and boiler sensors, enable residents to manage their energy usage more responsibly and improve grid flexibility through demand side response solutions.
