A tale of two cinemas: reduced air-conditioning energy use by 65 percent
One cinema installed Climate Wizard. The other didn’t. Same company, same city, very different results…
A major redevelopment of an Adelaide cinema complex included renovating four large cinemas into eight new smaller cinemas. In turn, the refrigerated air conditioning plant servicing the cinemas needed to be reduced in size and Climate Wizard was an integral part in achieving this.
Cost, noise reduction, energy savings and the following criteria were key design drivers for the cinema upgrade:
- Comfortable temperature
- No drafts
- Provide outside air to AS1668.2
- Individual temperature control
- Low capital cost
- Low noise within theatre
- Reduce running costs
- Meet EPA noise requirements
- Impact of services noise level on the adjacent apartment buildings
A second cinema within the same group, similar size and number of patrons per month, without pre-cooling of outside air with Climate Wizard, experienced higher energy costs over the summer period.
(with Climate Wizard Pre-Cooling)
(with Refrigerated Air Conditioning)
|No. of Theatres||11||14|
|Patrons per month||25,470||24,790|
|Floor Area (m2)||1,600||2,000|
At the conclusion of summer, the power bill between the two sites showed there was a significant difference. By installing Climate Wizard as a pre-cooling solution, the Rundle Street cinema is now reaping the rewards of substantial energy savings.
This design delivered energy savings without any additional capital cost to the project. Additional costs incurred from Climate Wizard, rooftop support platform and BMS controls were outweighed by the savings related to a reduction in size of the refrigerated air conditioning plant, acoustic barriers and associated energy savings.
– Reduced maximum demand from 250AMPS to 84AMPS
– Reduced power consumption
– Lower carbon emissions from the reduced air conditioning plant
– A greener footprint
HOW PRE-COOLING WORKS
The key is to hyper-efficiently pre-cool air before it enters the refrigerated air conditioning system. Compressors don’t need to struggle in extreme summer conditions when fed with pre‑cooled 18oC degree air from Climate Wizard. This significantly reduces the load on the system’s energy-hungry compressors.
