Demonstration project for Constructing Excellence in Wales

Welsh Assembly Government Llandudno Junction

Following extensive competition, Pochin Contractors Limited were awarded the highly prestigious contract to build the new Welsh Assembly Governments regional headquarters building at Llandudno Junction in October 2008. S I Sealy, as an integral part of the bidding team, was appointed to undertake the detailed M&E design and complex thermal modeling. The £20M+ development was completed in March 2010, and in order to meet the client’s strong desire to occupy a low carbon footprint / BREEAM Excellent building the development incorporates a number of low and renewable energy technologies (or LZCs).

At the heart of the low carbon footprint technologies is the on-site energy center housing the large scale Biomass boiler plant and Ammonia Chiller plant. In addition to Chilled water, the facility also benefits from a small scale pond water cooling loop, to provide free cooling to the air handling plant.

As would be expected, the building has many state of the art technologies for BMS control, lighting control, alarms, access control, etc all of which are fully integrated to provide a truly intelligent building capable of off-site control & monitoring.
