How Local Governments Convert Unexpected Places into Field Hospitals
May 3, 2020
As hospitals worldwide are faced with influxes of patients due to COVID-19 coronavirus pandemic, local governments are converting unexpected places into field hospitals and treatment wards.
Cities across the world are converting major event spaces typically used for major tradeshows and conventions into alternative care facilities. Elsewhere, hotels and university dormitories are also being repurposed to house non-COVID-19 patients and to help relieve the burden on local hospitals. While using an exposition center or a dormitory as an alternate care facility may have seemed like something out of a science fiction story several months ago, today it is, unfortunately, a global reality.
One important factor to consider when repurposing spaces for healthcare facilities is air flow. The CDC and ASHRAE have rigorous guidelines for air exchanges per hour for airborne contaminant removal and ventilation specifications for healthcare facilities. So how do facility managers achieve the most optimal air flow for buildings not originally intended for healthcare use? Below are tips for consideration:
- Audit the space and develop a plan: conduct an audit of the building to understand the challenges – looking at airflow, humidity as well as other building management areas like access control, fire and life safety to energy savings – and use that information to develop a plan. It’s important to know what options exist to convert the space, identify what needs immediate action and what items can occur over a longer time frame.
- Adjust the airflow: look at the overall design of the airflow to ensure that the circulation of fresh air occurs multiple times a day to help remove undesirable compounds for a building. While it may be difficult to achieve the type of air pressurization required for isolation in a large, open space, there are ways for smaller spaces like dorm rooms to change the HVAC settings per room and add overlay capabilities to create an isolation ability for a room or wing of the building.
- Employ remote monitoring: use remote monitoring tools to improve building performance and help reduce downtime through proactive and predictive maintenance.
- Evaluate fire and security systems: determine if the fire and life safety systems and security system, in particular access control and video cameras, require updating to better suit needs of the alternative care facility. From a fire and life safety system, using advanced fire detection system, low frequency sounders and strobes and mass notification systems can help ensure patient and medical team safety. From an access control perspective, the space may require restricted access for specific areas to help eliminate cross contamination.
Honeywell recently helped with the conversion of the Miami Beach Convention Center into an alternative care facility in just two and a half weeks. “Our focus at the site was on the building management system including airflow and chiller management,” said Jose Simon, vice president and general manager of projects, Honeywell Building Solutions. “There are dramatically different airflow needs when you look at a large, open space like the MBCC than you would have in a traditional hospital setting. We adjusted the BMS for more fresh air exchanges and added overlays to improve overall airflow.”
Facilities that have a good base infrastructure and that can maintain directional airflow and containment are valuable potential assets as alternative care facilities.
