What’s so special about Clubhouses?

The Complexities of Designing HVAC Systems for Clubhouses  

Clubhouses are unique among buildings. They house restaurants, community centers, banquet halls, entertainment complexes, retail spaces, fitness and spa centers and even offices all wrapped up into one facility! 

Dripping Diffusers
The clubhouses' unique nature is one of the major reasons why faulty HVAC systems are common; especially in humid climates such as Florida.

Perhaps, one of the most frequent issues that engineers uncover during a due diligence survey is a facility operating under a severely negative air pressure condition.

Common Symptoms of Negative Air Pressurization  
  •  A lack of fresh or clean air, instead a musty smell or other bad odors lingering in the air
  • Condensation on the Diffusers
  • Visible Mold or Mildew Growth along with Moisture on the Walls 
  • Sticky or Damp Furnishings
  • Varying Temperatures Throughout the Facility 
  • Stagnant, Stale or Heavy Air that causes Humidity or Condensation 
  • A Rush of Air or Draft when Opening an Exterior Door 
According to Bob Davenport, RGD Consulting Engineers' Principal Engineer, who has over 35 years of experience designing HVAC systems, "Operating a clubhouse with severely negative pressure can result in serious indoor air quality problems over time." 

Solutions

 If not caught before the start of microbial growth, negatively pressurized facility can be a costly issue to rectify. This is why having the proper HVAC equipment and a good maintenance program is important to preventing issues such as negative air pressure from occurring. 

Ensuring that the clubhouse building is equipped with 100% outside air pre-conditioner, runs continuously and supplies a constant and equal volume of dehumidified outside air to the building is key to maintaining the air pressure. 

There are a variety of methods for achieving this goal, and the most effective HVAC design system can be determined by a professional engineer after completing a thorough survey of the facility's systems. However, even the best designed HVAC systems can fail when they are not maintained. 

Just as important as working closely with an engineer for the design of your facility's HVAC system, is the creation of an aggressive maintenance program.   With these two factors planned well, your facility's HVAC system will stay balanced and healthy for years to come.
