HVAC Case Study
Aveley Secondary College

Project Requirements

The construction of Aveley Secondary College in Perth’s north-eastern suburbs was completed in 2017. The college intake covers years 7 to 12. The college required a total climate control solution to provide comfortable temperatures throughout general learning areas, open learning areas, and the information resource centre. The air conditioning plant specification required energy efficiency, a proprietary switch plate (reducing supply and install costs), and variable speed control.

Challenge

Considering the type of application, it was important to find a control solution that could be used across different product technologies. Avoiding the use of different control panels for each unit. The school also required the delivery of an energy-efficient solution with less humidity to preserve the life of books in the library application. Reverse cycle systems were too costly to run as a stand-alone solution.

Solution

Stand-alone Braemar RPC (51) and RPA (8) evaporative units were installed to provide a comfortable, consistent temperature and fresh air to the many general learning and open areas throughout the site. Smart drain kits measure total dissolved solids (TDS) to maximise water quality and minimise waste.

The information resource centre and staff common rooms are cooled by seven Climate Wizard CW-P15 units, which improved the absolute humidity of the space in comparison with a standard evaporative cooling solution. Natural Gas heating and ventilation were provided using an AIRA HCV unit.

“Seeley International were able to provide a total solution
using different technologies with only a common proprietary control panel.”

Benefits

The decision to go with a combined HVAC solution servicing general learning areas, the information resource centre, and common areas has provided:

• Reduced electrical demand and energy consumption
• A cooling solution that integrates with the school’s solar power performance objectives
• Improved Indoor Air Quality, particularly where needed in learning environments
• A flexible system allowing Free Cooling in mild conditions
• Specified climate conditions supporting individual building requirements
• A common control platform for ease of operation by school personnel
• Exceeds the minimum O/A requirements from Australian Standard AS1668.2.
