REYNAERS ALUMINIUM PROVES ENERGY EFFICIENT FOR COUNTY HALL

Bright, airy and a need to reduce energy consumption by 40 per cent were the requirements when Reynaers Aluminium was contracted to provide their quality aluminium window and door solutions for the County Hall in Trowbridge.

Run by Wiltshire County Council, the £22 million refurbishment incorporates a 1930s civic building and a tired 1970s office extension with an underutilised external courtyard. With many stakeholders operating out of the town centre building, flexibility for future developments was key to the design as well as the heavy emphasis on energy efficiency.

The external courtyard is now covered with a new ETFE ‘bubble’ roof, creating a vibrant public space between the existing buildings. The remaining sides of the courtyard are opened up to a new public library, dining area, registry services and meeting rooms, utilising Reynaers glazing systems CW60 SC and capped, CW50 capped, Eco windows and doors and the heavy duty Vision 50 ground entrance.

Offering high performance solutions for a range of specifications, Reynaers CW50 curtain wall systems provided the optimum choice for both thermal insulation and flexibility of design for much of the glazed facades. For the larger, heavier glass surfaces, the thermally improved CW60 curtain wall system – ideal for renovation projects due to its ability to hold a weight of up to 450kg per glass panel within sloping, vertical and curved constructions, was installed.

Reynaers Eco windows and doors were used for their aesthetically pleasing design combined with high energy efficient properties. These offer a significant contribution to overall efforts to reduce energy consumption due to their 2.20 W/m²K Uf-value, meeting the latest thermal insulation requirements.

Providing 200,000sqft of modern open plan working environment for 1,500 Wiltshire Council employees alone, extremely high durability within ground floor windows and doors was vital. Reynaers Vision 50 door solution is designed specifically for heavy traffic areas such as shopping centres so was the natural choice for the County Hall. Available with a variety of mechanisms for both inward and outward openings, these too provided the high performance and durability along with the flexibility required to meet the aims of the project.

Paul Duffy, Sales Director of Reynaers Aluminium said: “There were two key requirements for this project; the need to reduce energy consumption significantly, and the need to incorporate an element of flexibility in the design for future developments within the complex.

“The Reynaers Aluminium solutions identified for installation were all developed with these needs in mind and have been proven many times before to deliver optimum results, so we are confident they will assist considerably to the overall project aims.”

The Main contractor for the project was Kier, working with fabricator System Glaze and Stride Treglown architects. A BREEAM ‘excellent’ rating has been targeted due to the high level of energy savings made via a culmination of energy efficient glazing, thermally upgraded walls and roof and a services overhaul.
