Refurb transforms energy and comfort

One Creative Environments, displacement ventilation, natural ventilation, solar gain
A new lease of life for the Peirson Building at the University of Worcester sees energy and comfort issues addressed by One Creative Environment.

The £1.5 million transformation of the Peirson Building at the University of Worcester into a multi-functional learning and support space has overcome previous environmental problems, which included ineffective ventilation and temperatures in excess of 30°C because of the south-facing facade and wide use of PCs.

Consultant One Creative Environments use thermal modelling to demonstrate existing energy inefficiencies in the building and how they could be addressed. The number of students using the building ranges from 50 to 400 at any one time.

One’s solution was threefold.

The first was a low-velocity air displacement system to introduce air at low level throughout the building, depending on occupancy levels. The regular circulation of fresh air helps regulate temperature.

Next was an automated natural-ventilation system to reduce internal temperatures.

Thirdly, the windows of the facade overlooking the main study area were treated to reduce solar gain.

To further improve user comfort and energy efficiency, the lighting system was completely overhauled to include LED lighting with automated controls.

Under the soft-landings approach, regular feedback is being obtains from users to gauge how they perceive internal environmental conditions, which has enabled facilities managers to make appropriate changes.
