Natural ventilation system wins Green Oscar

A University of Cambridge spin-out was named the Most Enterprising New Market Entrant of the Year at the so-called Green Oscars.

E-Stack, which started life in the BP Institute at the university, took the prize at the Global Renewable Energy Awards for its low-energy ventilation for winter.

The company’s system, which is based on principles of natural ventilation, allows for fresh air to be circulated around a home while keeping it thermally comfortable.

Cold fresh air is brought in from outside and is mechanically heated on its way into the home, while warm air is let out and some of its heat is used to warm incoming air.

Dr Shaun Fitzgerald, E-Stack’s managing director said: "Our technology has the ability to reduce energy consumption in buildings by a factor of two, and given that 40 per cent of all energy in the developed world is used by buildings, the potential impact of the E-Stack system on the energy market is enormous."

E-Stack has also won the East of England Energy Group Energy Innovation Award and the Low Carbon Trophy.

Tests revealed the system had positive results at Queen Alexandra College in Birmingham and Unity College in Northampton.
