An eco-friendly building is helping to put Carillion firmly on the national sustainability map for both Design and Construction after winning praise from government ministers.

Carillion's eco depot puts the ability into sustainability An eco-friendly building - which is the centre piece of a brand new GBP8m development - is helping to put Carillion firmly on the national sustainability map for both Design and Construction after winning praise from government ministers

York's first eco-friendly council building - which is thought to be the largest timber-framed straw-clad structure in Europe - has been heralded by North Yorkshire MPs as a ground-breaking eco project.

York MP Hugh Bayley praised the building's design and called on other local authorities to visit the city to learn from the development and use the same technology.

Mr Bayley added: "It is a really good project demonstrating environmentally sustainable construction.

This is an excellent project and we are calling on other local authorities to visit the ecoDepot to learn lessons from it".

The impressive building, which is the centre piece of a brand new GBP8m works depot is home to the City of York Council's Commercial Services department.

The whole depot is a national exemplar of sustainable construction with real time monitoring of its performance and will be used to manage the City of York council's housing, waste and roads needs.

Locally grown bales were used to provide the wall insulation which is seven times more efficient than building regulations advise.

The straw bale is encased in a timber surround and reinforced with steel mesh prior to three coats of lime render being applied to each face, producing a standard panel of 2.9m high , 2.1 wide and 0.5m thick weighing in at 1.5 tonnes each.

The design maximises the use of natural daylight and ventilation through window sensors which can detect high temperature, rain or high wind and open and close accordingly.

The full height window sections were selected to compliment the straw clad panels and maximise on natural light and ventilation.

A wind turbine due to be installed in 2007 and solar panels to generate energy for the site - including a rainwater collection system so rain water can be recycled and used to wash depot vehicles rather than using clean tap water - is also an eco feature.

The substantial array of workshop buildings have been designed to shed water to a central rainwater harvesting underground tank and which is being utilised by the industrial vehicle wash facility provided.

Previously, council vehicles were washed at the depot using tap water costing the council a total of GBP25,000 a year.

With the new system, vehicles will be washed with recycled 'grey' water, reducing water consumption by 50%.

The south facing roof of the eco building has a photo voltaic system installed, helping to generate electricity for the buildings lighting system.

And, solar thermal panels are planned to be installed on the ancillary buildings sufficient to suit the site needs for hot water.

The eco building also includes an Interpretation Room, this will provide an area for training on sustainable building design and will be used as a national resource for learning and education on sustainable construction.

Carillion, senior contracts manager Brian Dunn said: "It has been great for Carillion to have been part of such a ground-breaking project which has gained national recognition.

"Helping businesses to embrace sustainable solutions is one of our key strengths." "The project has been a real success given the close co operation and support offered by not only the Carillion design team, the Carillion regional civil engineering and building staff but also the City of York management team and their consultants".

Eco facts:.

- The Eco Depot office will give a 76 per cent reduction in energy use compared to a traditionally built, air conditioned office of the same.

size.

- The energy efficiency of the EcoDepot office will give savings of 155 tonnes of carbon dioxide per year.

- Water consumption will be reduced by 50 per cent when recycled rainwater is used for washing vehicles.

- Electricity generated on site, from renewable sources will provide 12 per cent of the amount currently used.

- Environmentally-friendly materials will save 1,746 tonnes of carbon dioxide.

- Under floor heating will save an additional 40 per cent on heating bills and the building's design will maximise the use of natural daylight and ventilation.
