At AME, strong projects begin with strong collaboration. A big part of that is answering the smart, strategic questions we get from architects, clients, and owners throughout the design process.
Whether it’s about choosing the right HVAC system, planning around limited space, or meeting energy goals, our answers help build trust and support better project outcomes. Below, we’re sharing some of the top design questions we hear most often — and how we approach them with real-world solutions.
What are our options for mechanical systems?
This is the most common starting point. The right mechanical system depends on several priorities — including cost, sustainability, performance, and maintenance.
To support early decision-making, we provide a Mechanical Systems Presentation that outlines system types, their pros and cons, and how each aligns with your project goals. There’s no universal solution — we tailor recommendations based on what matters most to your team.
How much space will the mechanical system require?
Space is valuable. More room for HVAC means less for tenants or revenue.
We collaborate early to design space-saving mechanical systems. That could mean integrating equipment into the building envelope, locating it externally, or using pre-packaged solutions. We also engage user groups and building operators to understand project-specific challenges, concerns, or opportunities — so that the systems fit and function efficiently long-term.
Can we hide the mechanical equipment?
Aesthetics are always part of the conversation. In some cases, this means showcasing select mechanical elements — but more often, systems need to be integrated seamlessly into the architecture. We work closely with design teams, so mechanical systems support the building’s form, not distract from it.
That could mean:
- Integrating ductwork into trusses or architectural features
- Using architectural screens, louvres, or cabinets as part of HVAC design — as seen in the Pender Harbour Ocean Discovery Station (PODS) where passive design and curved architecture drove a custom mechanical layout
- Concealing equipment behind façade elements or within thickened floors — as demonstrated at the Esquimalt Gorge Park Pavilion
Ultimately, we balance performance and visual impact, so the mechanical systems do their job and look right doing it.
How will we maintain the system and what will it cost to operate?
Typically, owners want low-maintenance, energy-efficient systems — and we design accordingly. Our approach emphasizes:
- Simplified design that avoids unnecessary complexity
- Locally supported equipment for ease of service and parts availability
- Accessible layouts for controls and key components
- Proven control sequences that support reliable day-to-day operations
We engage operations staff early and work with equipment suppliers to select energy-conscious systems that align with long-term goals.
During retrofit analysis, we assess both capital and ongoing costs (including energy use and GHG emissions) to support more informed decisions.
At handover, we help streamline operations by coordinating:
- Comprehensive O+M manuals
- Training sessions for building operators
- Follow-up check-ins to verify system performance
We remain involved post-occupancy to support reliable, cost-effective operations and respond to emerging needs over time.
How does mechanical design align with new codes and sustainability targets?
With evolving energy codes like BC Step Code or NECB, it’s critical that projects respond to both regulatory requirements and sustainability goals.
Our Energy + Sustainability team is involved early, helping to incorporate these factors into the design without compromising performance, flexibility, or budget. During the schematic design of a new building, using tools like energy modelling and our AME Compass, support decision-making around system types, energy strategies, and overall building efficiency onwards.
This integrated approach helps projects meet code while delivering lasting value.
What are you doing to make sure the system performs as intended?
Smooth operation goes beyond handover. Even great systems need coordination and fine-tuning.
True performance comes from understanding how design elements interact — and from close collaboration across disciplines. Integration matters more than specs alone.
Key performance questions we often explore include:
- How do systems behave during shoulder seasons?
- Are sequences tuned for part-load conditions?
- Do emergency protocols reflect the client’s operational priorities?
- Is pressurization aligned with envelope performance and energy use?
- How do solar loads affect comfort in open spaces?
These factors, if overlooked, can lead to costly operational challenges. Instead of quick fixes, long-term performance depends on blending engineering insight with hands-on field experience to create systems that truly work together.
Which sustainable strategies actually stay in the project?
Not every sustainable feature survives value engineering — but many do, especially when they offer both performance and cost benefits.
We frequently see these strategies remain in place due to their long-term value:
- Heat recovery from ventilation and chilled water systems
- Air-source heat pumps
- Preheating domestic hot water using recovered energy
- Free cooling using outdoor air
- Water-to-water heat recovery in large or mixed-use buildings
These approaches often deliver measurable energy savings and operational efficiency, making them difficult to justify cutting. At the Acme Replacement School, for example, we worked closely with the design and construction team to strike the right balance between capital cost and sustainability. The final approach included air-source heat pumps and high-efficiency core energy recovery in the ventilation system — solutions that supported energy goals while keeping the budget on track.
We also help owners understand the lifecycle cost impact of removing energy strategies — allowing for more informed decisions about trade-offs between initial savings and long-term performance.
