Communities are facing the impacts of climate change, including severe health consequences from
heat waves and wildfires. EPA launched a pilot project in 2021 called Schools as Community Cleaner
Air and Cooling Centers to address the combined hazards of extreme heat and wildfire smoke with
a focus on spaces that serve children. The goals of this project are to support practical strategies for
safeguarding children in schools during heat and smoke events.

Principals and school administrators can be champions for upgrades to filtration and cooling systems
that can keep kids and staff safe during the school day. Important first steps include engaging
partners, especially public health agencies, to understand the risks from extreme heat and wildfire
smoke and the role that schools can play in keeping community members safe. School leaders can
work with facilities managers to evaluate HVAC capacity needs, and gaps for school buildings. Outside
of building infrastructure, it is important to support training for staff and faculty, develop heat and
smoke plans, and provide parent and caregiver education and support. This fact sheet can help you
take the first steps towards upgrading school facilities for extreme heat and wildfire smoke mitigation.

HEALTHY LEARNING ENVIRONMENTS
BENEFIT SCHOOL SYSTEMS

Schools are central to the well-being of some of the most
vulnerable members of our community. In addition to
schools confronting challenges posed by the COVID-19
pandemic, the number of extreme heat and wildfire
smoke events is on the rise. Keeping children safe and in
school during dangerous heat and smoke days—in addition
to improving facilities to meet post-pandemic air quality
standards—is a strong investment for a school system.

Healthy learning environments equal higher test scores
and lower absenteeism. Asthma is a leading cause of
school absenteeism and poor outdoor and indoor air
quality are the leading causes. Students with uncontrolled
asthma score lower on standardized tests than other
students.1 Higher temperatures in the classroom can
not only be hazardous to children's health, but can also
adversely impact student performance on academic
work.2 Even modest improvements in room temperatures
have been shown to positively affect a student's ability to
perform tasks successfully especially those that require
concentration.

Schools and their partners can make investments that
alleviate these barriers to learning, help keep schools open
as a critical resource during heat and smoke events, while
also improving the performance and outcomes
for students.

WHO IS THE MOST AT RISK?

At the start of the pilot projects, EPA worked with counties
and school districts to conduct risk assessments to identify
which neighborhoods and schools were most in need
of air quality and cooling improvements. This process
involved mapping and screening using categories of data
that identify and evaluate the geographic areas that are
more at risk to heat and smoke and groups of people that
are most vulnerable. Some schools may be located in
neighborhoods serving people who are more vulnerable
than others to health impacts of climate change due to
social and economic factors. Figure 1 provides an example
of the categories of data that can be used to prioritize
facility upgrades. Schools may need to work with local
or county GIS staff, if available, to do this mapping and
assessment. And this process will be more relevant
for larger school districts with many facilities serving
different populations.

WHAT SPACES WILL YOU USE?

WHO WILL USE THIS CENTER?

Investments can be made for a specific space within your
school building that Could be used as a designated area
during extreme, heat and smoke event days. The best
spaces include those with the following features:

1.. High occupancy densities

2.	High cooling capacities

3.	Have permanent or temporary standby power
capability

4,	Won't impact normal school operations or function by
their use'

5,	Example spaces include: Gymnasiums, Auditorium,
Performing Arts Centers, Cafeteria

School administrators and decision makers will need
to discuss if it is appropriate to open to the school as a
cleaner air or cooling centers to members of the public
outside of school hours. Ear instance, the facility could
be open to families of students or specified at-risk
members of the nearby neighborhood. Rural schools may
already be used for broader community events and have
plans in place to make facilities open to the public. Based
On these conversations and policies., different groups
should be included in the decision-making team for the
school. The chart below outlines typical community
partners to engage:
