For over 80 years the Grand Pavilion in Porthcawl, Wales has dominated the town’s waterfront with its octagonal dome and eye-catching facades. Always intended as a multi-purpose venue the pavilion was a renowned dance hall of its day, but now hosts a range of functions including conferences, weddings, plays, musicals, comedy and variety shows.
The shell of the 1932 built Grand Pavilion has stood the test of time remarkably well, however other later additions such as the installation of modern stage lighting have had more adverse effects on the interior of the pavilion. In particular Bridgend Borough Council found the upstairs area of the main auditorium which seats 643 people had begun overheating, resulting in the audience having to watch shows in a stuffy and uncomfortable atmosphere. Concerned that this could potentially dissuade some patrons from rebooking at the Grand Pavilion again the Council decided to upgrade the heating system. They wanted something that was quiet and unobtrusive which could ventilate the area improving the indoor air quality while still maintaining the temperature.
As Bridgend Borough Council had worked with Jaga before on previous projects and have a well-established relationship it was aware of Jaga’s Oxygen system and identified it as the ideal all-round solution. Decision made the council specified four Jaga Strada radiators all equipped with Oxygen refresh units to be installed in the upstairs auditorium.
Jaga’s Oxygen technology is a low-energy combined heating and ventilation system equipped with discreet fan units that enable cool filtered air to enter from outside and refresh any interior. In the Grand Pavilion the Oxygen supply units, which are built into the Strada radiators, ventilate the auditorium while highly responsive Low-H2O heat exchangers provide almost instant warming when required.
A further important consideration was the external aesthetics of the louvres which allow the fresh air to enter from outside. Due to the Grand Pavilion being a listed building the vents on the outside of the pavilion extracting the fresh air had to pass an inspection from Cadw, who oversee the protection of historic buildings in Wales. Jaga responded by providing small and unobtrusive vents that were painted in a shade of lacquer similar to the exterior of the Grand Pavilion thereby providing a sympathetic finish.
