What's a common HVAC design mistake you see in commercial buildings, and what's a practical solution to address it? What impact does this solution have on energy efficiency?

One common HVAC design mistake I often see in commercial buildings is poor zoning especially trying to control large, varied spaces with a single thermostat. Offices, retail areas, and storage spaces all have different heating and cooling needs, but too often, they're lumped together under one system. At Georgio's, we've addressed this many times by recommending zoned HVAC systems or multiple smart thermostats, which allow different areas to be controlled independently. This means staff aren't too hot while the storeroom is freezing and energy isn't being wasted heating or cooling unused spaces. The result? Clients usually see a noticeable drop in energy use and better comfort for their teams and customers. It's a simple change that can have a big long term impact on both performance and bills.

A common HVAC design mistake I often see in commercial buildings is undersizing or oversizing the system. When the system is undersized, it struggles to maintain the desired temperature, leading to constant overworking and higher energy bills. On the other hand, an oversized system short cycles, which reduces its efficiency and increases wear and tear. A practical solution is performing a detailed load calculation based on the building's size, insulation, and usage patterns. This helps ensure the system is appropriately sized. By doing this, the system operates more efficiently, reducing energy consumption and improving comfort. In my experience, implementing this solution can lower energy costs significantly while also extending the lifespan of the HVAC system.
