INSIGHTS INTO HEALTHIER INDOOR ENVIRONMENTS: HOSPITALITY

The hospitality industry has been one of the hardest hit by the COVID-19 pandemic. As hotel owners and operators look to rebound from historically low occupancy rates, they must address safety concerns to restore guest confidence – and healthy building strategies are a key. A healthier indoor environment can help promote guest and employee safety in the short term, while enhancing the guest experience well into the future.

THE NEED

The ability to safely welcome back guests is critical to the very survival of many hotels and the financial well-being of the millions of people they employ. Current evidence has not identified hotel buildings among the highest- risk environments for COVID-19 transmission or superspreading events. 1 Still, hotels must improve perceptions of real and perceived safety concerns through risk reduction strategies and education in order to attract customers to visit. 2

environments is essential to combating the spread of COVID-19 and continuing to reopen the industry. But research has shown the benefits go beyond infection control. Factors including humidity, lighting, noise and even a sense of security can impact guest sleep, concentration and overall health. With this in mind, addressing the challenges of the COVID-19 pandemic also presents opportunities to improve the guest experience and deliver on shifting expectations moving forward.

ACTIONABLE STRATEGIES AND SOLUTIONS

**There is no single strategy for creating and sustaining healthier

hotel environments.
Carrier can help inspire confidence in returning to normal with a layered defense approach, implementing all levels of control strategies , which can help reduce risk and maximize benefits.
For engineering controls, Carrier can provide expert guidance to help support hospitality customers with solutions and services for the entire lifecycle.
We’ve outlined a few specific areas here.**

VENTILATION

Strategies

Buildings should eliminate or reduce air recirculation – improving the intake of fresh outdoor air – to the greatest extent
The use of active chilled beams for building air conditioning can provide the opportunity to achieve low sound levels since fans

or compressors are not located in or near occupied spaces. 11

Solutions

Our rooftops unit (RTU) can improve the intake of fresh outdoor air, providing a reliable, flexible and energy-efficient
solution for healthier indoor environments.
Our air handling units (AHU) provide

a cost-effective improvement by inhibiting bacterial and microbial growth on the interior of the unit.

Strategies

In buildings with mechanical ventilation systems, existing filters can be upgraded to filters with efficiency ratings of at least F7 (ePM2.5 >65%), and up to the highest fine particle classification or even HEPA filters, **if the available pressure drop of the system**
Portable air cleaners with high-efficiency particulate air (HEPA) filters may be useful to

supplement fresh and clean air and reduce exposures to airborne particles.
And because potential viral sources could be in various locations within a room, it may be beneficial to have
several units that meet the target clean air delivery rate (CADR) values rather than a single larger unit. Portable units are also recommended when budget constraints prevent other recommended capital improvements.

Solutions

Carrier filtration technologies include various ePM filters and HEPA filters for particulate
Carrier also offers devices using UVC light, which are intended to target pathogens, and UV photocatalytic oxidation to help remove volatile organic compounds and improve indoor air quality (IAQ).
Carrier’s OptiClean™ air scrubber uses HEPA filtration to provide cleaner indoor *** An easy way to supplement an HVAC system without replacing**

or modifying existing equipment, the OptiClean plugs into a standard outlet and can be easily rolled into guest rooms or other areas of a hotel.

Strategies

Ensure that there is adequate ventilation and filtration through a process of commissioning and Commissioning and testing should be performed by trained individuals and should be performed at regular intervals.
concentrations are measured at levels below 1,000 ppm while facilities are purification in the building. occupied, then the outdoor air ventilation is likely performing according to
acceptable minimum standards. Higher CO 2 concentrations may indicate that other strategies for increasing outdoor air ventilation are necessary.
To promote healthy indoor environments, real-time monitoring for a variety of pollutants and IAQ parameters including (but not limited to) carbon monoxide, ozone, volatile organic compounds, formaldehyde and other aldehydes, temperature, humidity, noise and light are

Solutions

Remote Airside Management provides continuous validation of IAQ parameters, periodic checks of equipment health and continuous airside commissioning, enabled by a command
Hotels should implement multi-parameter IAQ monitoring to baseline performance, identify deficiencies and enable demand control ventilation for specific contaminants of
