Prison Climate Control Act

Summary#

This bill would require the Federal Bureau of Prisons (BOP) to prepare for and respond to extreme heat and cold in federal prisons. It orders installation or updating of heating, ventilation, and air conditioning (HVAC) systems and temperature sensors in every human-occupied space. The bill also sets rules on monitoring, staff protections, supplies for inmates, studies and guidance from CDC, reporting to Congress, and annual Inspector General checks.

• Main change: BOP must install or update HVAC and place temperature-reading devices in every human-occupied space in BOP facilities within 5 years.
• BOP must monitor temperatures until the devices are fully installed.
• BOP must write and enforce mandatory standards on heat and cold stress for inmates’ work, recreation, and conditions of confinement.
• CDC must study the health effects of extreme temperatures in BOP facilities and the BOP must finalize rules to protect medically vulnerable people within 1 year.
• BOP must use wet-bulb globe temperature (WBGT) guidelines for staff heat exposure within 1 year.
• BOP must provide cooling items (water bottles, fans, cooling towels) and winter items (clothes, blankets) free, outside the commissary, when temperatures reach levels the Director calls dangerous.
• The bill requires electronic records for seasonal staff training, periodic reports to Congress on costs and illnesses, and annual IG inspections and reports.
• It authorizes “such sums as may be necessary” for fiscal years 2026–2031 for HVAC work.

What it means for you#

• Incarcerated people (in federal prisons):

  • Cells and indoor spaces would get temperature sensors.
  • HVAC systems must be installed or updated over five years. This could change how hot or cold cells feel.
  • If temperatures are judged dangerous, inmates can request free cooling or warming items without buying them from the commissary.

• Prison staff and health staff:

  • BOP must use WBGT-based limits for staff to account for humidity and heat risk.
  • Staff must get seasonal training on preventing and spotting heat-related illness. Completion must be tracked in an electronic system.

• Bureau of Prisons (administration):

  • Must make and enforce written heat and cold stress rules for daily operations and confinement conditions.
  • Must monitor temperatures until sensors are in place.
  • Must report costs and temperature-related illnesses to Congress on a set schedule.
  • Must provide items free outside commissaries when the Director declares temperatures dangerous.

• Centers for Disease Control and Prevention (CDC):

  • Must study the effects of extreme temperatures in BOP facilities and develop safety recommendations for the BOP.

• Inspector General / Congress:

  • The Justice Department IG will inspect HVAC systems, temperature devices, illness counts, and mitigation efforts each year and publish a report.
  • Congress will receive regular cost and illness reports.

• Who is not covered by this bill:

  • The bill applies only to correctional facilities operated by the Director of the Bureau of Prisons (federal prisons). It does not change law for state or local jails, unless those agencies voluntarily follow the same rules.

Expenses#

No publicly available information on a precise cost estimate is provided in the bill text or accompanying material.

• The bill authorizes funding as “such sums as may be necessary” for fiscal years 2026 through 2031 for BOP HVAC installation and updates.
• Expected categories of cost (not numerically estimated in the bill): purchasing and installing or upgrading HVAC systems; buying and installing temperature sensors; supplies for inmates (cooling and warming items) provided free; staff training and electronic record systems; CDC study work; IG inspections and report production; ongoing maintenance and monitoring.
• The bill does not give a dollar estimate, cost breakdown, or a fiscal note.

Proponents' View#

• The bill appears intended to reduce harm from extreme heat and cold in federal prisons. Possible reasons to support it include:
  • It could improve health and safety for incarcerated people, especially those who are medically vulnerable.
  • It would create measurable monitoring (sensors and reporting) so officials can know when temperatures are dangerous.
  • Requiring WBGT-based limits could better protect staff by accounting for humidity as well as temperature.
  • Annual IG oversight and regular reports to Congress aim to create accountability and track progress.

Opponents' View#

• The bill leaves several practical questions unclear or potentially challenging:
  • It does not give a cost estimate or funding amount, so the total federal cost is unknown.
  • The bill lets the BOP Director decide what counts as “dangerously high” or “dangerously low” temperatures. This leaves room for inconsistent thresholds across facilities.
  • The timeline (install or update HVAC within 5 years) may be difficult in some locations, but the bill does not explain prioritization or temporary measures beyond interim monitoring.
  • The bill requires temperature devices in every human-occupied space, including cells, but it does not address who can access the temperature data, how long data are stored, or privacy/security of the data.
  • It does not spell out enforcement steps or penalties if facilities fail to meet the new standards.
  • The requirement to provide items “outside of the commissary, at no cost” shifts the cost of those items to BOP or federal funds, but the bill does not describe how that will be funded.
