Sharing Future-Focused HVAC Insights With WA’s Property Industry

At a Property Council of WA Industry Insights event, Froster Engineering was invited to present on how mechanical services, often overlooked during early-stage planning, can play a critical role in both the short- and long-term performance of commercial buildings.

Our presentation, “Stay Ahead of the HVAC Curve”, focused on how base-build HVAC design can directly impact leasing success, energy compliance, operational cost, and long-term tenant satisfaction.

The problem we’re solving

Too often, we see base-building HVAC systems designed for today’s tenant or a single fitout, without considering how the space will evolve. This leads to:

• Costly rework during tenancy changes
• Inefficient systems that struggle to meet updated code
• Higher long-term running costs
• Missed opportunities to improve energy ratings and sustainability

Our goal was to help developers, asset managers, and consultants understand how early HVAC decisions can unlock performance benefits over the life of the asset.

Key strategies shared in the presentation

1. Design for flexibility, not just the first tenant
   We showed examples of how to zone spaces and design air systems that support multiple tenancy types, ensuring adaptability without requiring expensive redesigns. By decoupling services, and using scalable ductwork and plant access points, you can accommodate everything from office space to light industrial.
2. Optimise for energy performance from day one
   Base-building HVAC plays a major role in meeting and exceeding Section J requirements of the National Construction Code. We explained how systems like Indirect Evaporative Cooling and Maisotsenko Cycle technology can deliver ultra-low energy performance while still meeting ventilation and comfort standards, achieving COPs of up to 12:1, compared to just 3–4.5:1 in traditional systems.
3. Leverage psychrometric energy for smarter cooling
   We introduced the concept of psychrometric energy, clean, natural energy found in our atmosphere, and how it can be harnessed through indirect evaporative systems for high-efficiency cooling. These systems offer low running costs and 100% fresh air, making them a great option for commercial and warehouse hybrid spaces.
4. Think long-term cost, not just CAPEX
   Many developers prioritise upfront cost, but mechanical systems contribute heavily to operational budgets. We explored how smarter plant selection, access design, and service coordination can reduce long-term spend and improve building value.
5. Engineer-led coordination leads to better outcomes
   We advocated for early and ongoing collaboration between engineers, architects, and builders. When mechanical design is considered from the start, we can avoid costly clashes, preserve ceiling heights, and improve constructability, all while protecting the design intent.

The message to industry

Don’t treat HVAC like an afterthought. By engaging mechanical engineers early and thinking beyond compliance, property teams can design more valuable, efficient, and adaptable buildings.

Whether you’re building speculative developments or custom fitouts, the right HVAC approach is key to staying ahead of the curve, both in performance and profitability.
