85 Spring St

Located in the heart of Melbourne’s CBD, 85 Spring St is an existing 10,000sqm commercial office building. Following a prolonged period of vacancy, the asset is being prepared for a return to full operational service.

Challenges

Under the Commercial Building Disclosure (CBD) Programme, the building owner is required to commit to specific NABERS energy efficiency improvements before the premises can be re-let. Because refurbishment works were already well progressed and the delivery programme was exceptionally tight, it was critical to rapidly identify, model, and sequence technical upgrades without disrupting the construction timeline.

Technical Solutions

Co-Perform collaborated closely with the project team to navigate the intersection of regulatory compliance and asset repositioning. Our approach focused on high-impact, data-driven interventions.

Key consultancy phases included:

• Gap Analysis & Modelling: We utilised detailed thermal and systems modelling of the existing building fabric and mechanical services to establish a performance baseline.
• Strategic Upgrade Sequencing: We developed a wide range of upgrade options, categorising them into two distinct phases:
  • Pre-Tenancy Upgrades: Works that could be most efficiently executed while the building remained vacant.
  • Operational Upgrades: Sustainable improvements designed for phased implementation over time during the building’s operational life.
• Owner Evaluation Support: Our analysis provided the building owner with a clear cost-benefit framework, allowing for informed decision-making regarding capital expenditure and long-term energy performance.

This strategic NABERS roadmap ensured that 85 Spring St met its statutory requirements while providing the owner with a commercially viable path to modernising a significant CBD asset.
