The next step in our green mission

IT IS known across the city for its environmentally- friendly ethos and boasting one of the city's greenest buildings.

Now, Hull's InterTech is taking another step in the world of eco-friendly technology.

The commercial design company in Priory Park will add to its "egg whisk" turbines on the roof of the building, with the addition of a further 20 "miniature" wind turbines.

Phase two of InterTech's wind power plans will be carried out later this year and will see the 20 small turbines fitted along the fascia of the building.

Director Andrew Fenton said: "We produce more energy than we need but at the moment, we can't capture that energy. The new wind turbines will combat this problem and allow us to store it for future use."

The smaller turbines, which Mr Fenton said are mainly used in the marine industry on boats and are only 1m in diameter, are designed to turn at all times of the day, meaning they will provide a viable addition to the two already on the roof.

Mr Fenton said: "The new turbines will give the power we need and will fill the gap for us.

"Our main goal is to get the building off the grid and we think we can achieve that.

"The new turbines will help us with this goal as, at the moment, everything we produce goes straight back to the grid."

The unused electricity generated by the wind power can be stored in a battery for use when there is no wind.

Mr Fenton said: "We can draw back on this energy when we don't have prevailing wind or daylight and with the added 20 turbines, it will get us almost three kilowatts more of energy, allowing us to top up the batteries all the time."

It is not just wind power that helps the company conquer the green market.

It also has rooftop solar panels, LED lighting throughout and a rainwater recycling system – all of which help the company benefit from an 83 per cent reduction in energy consumption.

Mr Fenton said the building costs about £1,200 per year to run. Without the energy conscious factors, it would cost about £23,000.
