Refurbishment to Cat A of an existing dual wing three storey office development in Solihull – Phoenix Building.
There are three main air handling units in the roof plant room that incorporate the heating and cooling via VAV ventilation. A gas fired boiler plant feeds primary chilled water coils and secondary LPHW coils. Gas fired cylinders provide hot water to two central toilet cores. The cold water is stored in roof mounted tanks before being boosted to serve all areas.
The original Belimo motors controlling the VAV boxes were obsolete and providing inaccurate control across the system. Therefore, we replaced the entire range (approximately 470) with current up to date models. These were then calibrated to provide the original design duty in association with the BMS system.
The original ground floor canteen and kitchen area was stripped out so that the space returned to a Cat A configuration. This included modifications to the ductwork system and also the introduction of new VAV boxes.
For the new kitchen and canteen area we have provided a dedicated domestic services and extract ventilation.
We have supplied and fitted new sanitaryware appliances to the refurbished toilet cores.
