Air Conditioning Beyond the Basics
Great AC design is not just about cooling. It is about planning, comfort, efficiency, and long-term performance. These are the key points every architect should guide the client on.
1. Right system for the right project
Not every space needs the same AC system. Choosing the right type, such as split, cassette, or ducted/VRF, ensures better comfort, better use of space, and smarter budgeting.
2. Consider part-load performance
Air conditioners often run below full load, so part-load efficiency matters. A system that performs well at partial load can reduce energy use and improve long-term value.
3. Plan for maintenance access
Good design always includes enough access for servicing. Proper clearance around the unit makes maintenance easier and helps avoid future problems.
4. Dew, condensation, and drainage
Poor drainage can lead to water damage, stains, and unhappy clients. Proper slope, traps, and drainage testing are essential before handover.
5. Outdoor unit location is crucial
The outdoor unit should be placed in a well-ventilated, shaded, and easy-to-service location. Wrong placement can cause noise, hot air recirculation, and poor performance.
6. Control strategy matters
Smart control systems improve comfort and reduce energy use. Features like zoning, scheduling, occupancy sensing, and BMS integration can make a big difference.
7. Electrical and load planning
AC planning goes beyond the unit itself. The complete electrical system must be considered. Dedicated circuits, proper sizing, and future DB space help prevent issues later.
8. AC and architecture work together
AC should be integrated into the design, not added as an afterthought. Concealed ducts, linear grilles, and return-air planning create a better and cleaner result.
9. Future-proof your design
Good design today should still work tomorrow. Planning for extra capacity, spare conduits, and future controls keeps the system adaptable as needs evolve.
Design for today. Be ready for tomorrow.
How many of you are aware that AC planning involves much more than just choosing a unit?
