Overview
As buildings are being built with higher quality construction methods, balanced ventilation is more important than ever. An unbalanced structure results in low indoor air quality (IAQ), causing poor conditions for hotels. All buildings are susceptible to poor indoor air quality, not just homes. You'll be learning more about the problems unique to a hotel and the solutions S&P USA Ventilation Products Export Department can provide to increase indoor air quality.
Understanding Indoor Air Quality in Hotels
IAQ refers to the air quality within and around buildings and structures. The air indoors is often 2-5 times more polluted than the air outside due to buildings' tighter installation. The Environmental Protection Agency (EPA) now ranks indoor air quality as one of the TOP FIVE environmental health risks.
Poor IAQ can result in allergies, headache, cough, asthma, and other breathing difficulties. Long time exposure can lead to cancer, liver disease, and kidney damage. A buildup of Carbon Dioxide (CO2) can negatively impact thinking and decision making. Hotels have many unique problems when dealing with indoor air quality, from location to higher cleaning standards. These problems can be solved with the right ventilation solution.
Hotel-Specific Indoor Air Quality Challenges
Exterior Pollution
The location of the hotel plays a vital role in the quality of the air. Often located in city centers and near airports, outside air pollutants are more common than those found in a suburban setting. Exterior pollution includes:
- Smog from urban environments
- Traffic emissions from vehicles
- Emissions from aircraft at nearby airports
- Pesticides from landscaping and maintenance
Indoor Pollution
The way the hotel is built and cleaned is negatively impacting the indoor air quality. For example, glue from carpets and Volatile Organic Compounds (VOCs) from cleaning supplies are build-up creating lower quality of air. The occupants contribute to the increase in VOCs with the use of perfumes and aerosol hairsprays. Other indoor pollutants include:
- Paint and construction materials
- Indoor smoking (where permitted)
- Steam from showers and hot water systems
- Emissions from dishwashers and cooking equipment
- Cleaning chemicals and disinfectants
- Guest personal care products
Humidity in the Indoor Environment
As humidity increases considerably in hot and humid climates such as kitchen areas, the growth of mold and mildew arises within the building. This is true as well when a hotel has a gym, spa, or indoor pool. High humidity environments create ideal conditions for:
- Mold and mildew growth
- Dust mite proliferation
- Bacterial contamination
- Structural damage to building materials
The Exchange Rate Between Indoor and Outdoor Air
Unbalanced air exchange can cause the room to feel stuffy. This feeling is due to the lack of exhausting dirty air and bringing in fresh outside air. Poor air exchange results in:
- Accumulation of CO2 and other contaminants
- Stagnant air conditions
- Odor retention throughout the building
- Reduced guest comfort and satisfaction
S&P USA Ventilation Products Ventilation Solutions
The solution to all of these problems is balanced air exchange. S&P USA Ventilation Products recommends a good, better, best approach in meeting this goal.
Good: Supply Only or Exhaust Only
This solution provides new air to dilute the air or exhausts the dirty air. This solution allows the introduction of fresh air or the removal of old air but does not provide a balanced solution.
Better: Supply Fan + Exhaust Fan OR Filtered Supply Unit
Pairing an inline fan, such as a TD-Mixvent or motorized damper with an inline Exhaust fan such as a Premium Choice fan, will provide a balanced air solution.
Another option is to use a filtered supply fan, such as reFresh. This provides new air that has been filtered to remove outside particulates that would further contaminate the air.
Best: Filtered Supply Fan + Exhaust Fan or Energy Recovery Ventilator
There are two options for the best Outside Air Solution. It is pairing a Filtered Supply Fan (reFresh) with an exhaust fan, such as Premium Choice or TD-Mixvent. This provides a clean air supply while exhausting contaminated air.
The best option is an Energy Recovery Ventilator (ERV). This fan transfers humidity and temperature through a filter and core that does not allow contaminated air to touch clean air. In the long run, this saves energy.
Our focus is to provide Indoor Air Quality (IAQ) and energy-saving solutions for the hotel property to focus on their most valuable asset - Their guests.
