The Sydney Opera House is one of the first UNESCO World Heritage-listed buildings to receive a 6 Star Green Star rating, which represents ‘World Leadership’ in environmental and social sustainability operations.

This achievement is the result of continually improving the building’s performance, reducing its carbon emissions and maintaining its carbon neutral certification.

Honeywell has contributed to retrofitting the Sydney Opera House with Honeywell’s innovative, ready now technology to help support more sustainable operations and to reduce the building’s environmental impact.

As a globally recognized performing arts venue and World Heritage-listed icon, the Sydney Opera House operates 24/7 requiring close collaboration between Honeywell and the Sydney Opera House’s safety, projects, and service teams.

Together, they work to identify and implement solutions tailored to the unique needs of the building. This includes creating a technology system that monitors indoor air quality (IAQ), and relative humidity (rH).

Honeywell also worked with the Sydney Opera House in integrating more than 20 disparate subsystems in the building to help improve safety, energy and water usage in addition to implementing several innovations including electricity spot-price monitoring, extraction fan control in non-air conditioned (AC) areas and monitoring of cold room doors that remain open for too long.

They also worked on automating outside air control through real-time air quality data from the Bureau of Meteorology (BoM) as well as identifying potential energy saving opportunities in the building, including the installation of more than 60 water meters and more than 800 electrical meters.

These strategies help enable automated responses and alerts to changing conditions, which supports operational efficiency and provides a safer and more comfortable environment for staff, audiences and visitors.

“Sustainability is in the Sydney Opera House’s DNA. Architect Jørn Utzon incorporated sustainable design into the fabric of the building in the 1960s. Now, as we approach our 50th birthday later this year, we continue to look for ways to build on this legacy by embedding sustainable thinking into everything we do,” said Louise Herron AM, CEO, Sydney Opera House.

“Thanks to the long-term support from our Global Goals Partner Honeywell, the Opera House is working harder and smarter than ever before and I’m thrilled to see this recognised in such a significant way. It’s a testament to the power of meaningful partnerships in driving positive change.”

“The Sydney Opera House takes a thoughtful and deliberate approach to minimise its impact on the environment while providing a world-class experience for its occupants – all while carefully protecting its UNESCO World Heritage-listed status,” said Billal Hammoud, president and CEO of Honeywell Building Technologies. “This requires a careful balance and technologies, but most importantly, teamwork. The Honeywell team who service and support the Sydney Opera House every day closely collaborate with its engineering and sustainability teams to make sure the building systems are performing efficiently and we work to find innovative solutions to meet well-defined goals.”
