Many hotels and other high-rise buildings can develop indoor humidity issues causing high moisture levels. As a result, these problems can lead to damage to the building or discomfort to their guests without having the proper DOAS system into place. It is critical for business designers to implement cost-effective strategies to ensure their buildings are operating efficiently.
A proper DOAS system combined with interior conditioning strategies such as chilled beams or VRF systems can help control high humidity levels within a building. Preventing high indoor moisture is extremely important not only for the building but for the health of their occupants. The initial upfront could be a costly endeavor, however, the long term benefits of investing in a DOAS will far outweigh the short term cost.
Moisture Level in Hotels is Key
Moisture removal is the key component to optimal IAQ (indoor air quality) and occupant comfort. This can maximize the life of the facilities equipment and furnishings. The recommended range of human comfort (defined by ASHRAE) and desirable humidity level for interiors is around 65% relative humidity. Anything above 65% will yield the likelihood of microbial growth. One way to minimize the reheat energy associated with dehumidification would be through an energy recovery wheel (ERV). If you had an extremely hot and muggy day at 88°F and 60% RH, an ERV could reduce the outside air temperature down to 77°F and 60% RH.
Dehumidification often tends to be ignored because of the high cost and high energy expenditure of operating today’s buildings. Consequently, the lack of dehumidification in hotels can not only cause occupant discomfort but building damage as well. The best way to address this concern is to properly design a dehumidification system. Using a system with an energy recovery wheel is a great solution.
