Refurbishment to Cat A of an existing dual wing three storey office development in Solihull – Phoenix Building.
The existing building was constructed in approximately 2001. It is heated and cooled via a VAV ventilation system incorporating three main air handling units in the roof plant room. Primary chilled water coils and secondary LPHW coils are fed via gas fired boiler plant. Hot water is provided to two central toilet cores via gas fired cylinders. 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, the entire range (approximately 470) were replaced with the current 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 the space returned to a Cat A configuration. This included modifications to the ductwork system and the introduction of new VAV boxes.
Dedicated extract ventilation and domestic services have been provided to the new kitchen and canteen area.
The toilet cores have been refurbished in which we have fitted new sanitary appliances.
