How to read this. Facts link to their sources; anything marked proposed or inferred is the researchers’ suggestion, not a commitment by anyone named. Gaps are gaps in what we found, not faults.

Heat context

Known: Western/southwestern daytime hotspots coexist with humid urban and night exposure. Inferred: Combine work, housing and overnight recovery with warning-to-action design. Uncertain: Comparable ward-level exposure, health burden and nationally representative indoor monitoring. Are hotspots and frequencies of heat waves changing over time? (opens in a new tab)  · Diurnal asymmetry in heat stress intensification across Bangladesh, 1985–2024 (opens in a new tab)  · Bangladesh faces health and economic risks from rising temperature - report release (opens in a new tab) 

Plans and law

Warnings

Bangladesh Meteorological Department heat-wave warning portal (opens in a new tab)  · Heat Action Plan, Narayanganj City Corporation (opens in a new tab)  · Bangladesh Health National Adaptation Plan 2026 (opens in a new tab)  Proposed last mile channels: NCC plan proposes local media, SMS, loudspeakers, ward offices, religious/educational institutions and visits. Not verified as comprehensive operating coverage. Note: Meteorological warning, health action and financial payout triggers are separately authorised and validated. No universal WBGT/fan threshold supplied.

Rules for heat at work

Bangladesh Labour Act section 52 - ventilation and temperature (opens in a new tab)  · Bangladesh Labour Act section 58 - drinking water (opens in a new tab)  · Ministry of Labour and Employment legislative information (opens in a new tab)  Verified foundation: Ventilation, suitable workplace temperature and drinking-water provisions. Why this is left blank: Not verified after full 2026 amendment/rules review, not a claim no protection exists. Equity: Formal-establishment provisions cannot be assumed to reach all informal, migrant, domestic or self-employed workers.

Cooling and buildings

Bangladesh National Building Code 2020, Part 3 Chapter 4 (opens in a new tab)  · Bangladesh National Cooling Plan for implementation of Montreal Protocol (opens in a new tab)  · UNEP Ozone Secretariat country profile - Bangladesh (opens in a new tab)  · Six Seasons, Four Summers: how to solve fashion’s high heat problem (opens in a new tab)  · Creating cooler buildings in Dhaka - Cool to be Cool (opens in a new tab)  Approach: Proposed passive-first assessment with adequate active cooling where needed; select by humidity, building, task and power. Cooling trap: Loop cooling: poorly specified mechanical cooling can add peak demand and waste heat; refrigerant management and affordability would ideally accompany access. Cost examples:
  • Basic passive home retrofit estimate Location: Dhaka-region worker homes, engineering scenarios Evidence status: reported Upfront: Materials BDT: 7000 Installation BDT: 5000 Total BDT: 12000 USD as published: 100 Running: Additional kwh per month: 0 Additional electricity BDT per month: 0 Currency: BDT Publication year: 2026 Fx note: Source prints rounded USD pairs but does not disclose exchange rate used. No independent historical conversion added; comparison does not meet complete FX documentation standard. Source: Six Seasons, Four Summers: how to solve fashion’s high heat problem (opens in a new tab)  Limitations: Home size/specification, permissions, fire safety, airflow, water ingress, wiring and income would be worth checking locally. Zero added energy for passive scenario does not mean zero maintenance. Modelled cooling magnitude omitted; no safety certification or universal price.
  • Minimum hybrid home retrofit estimate Location: Dhaka-region worker homes, engineering scenarios Evidence status: reported Upfront: Materials BDT: 17500 Installation BDT: 8000 Total BDT: 25500 USD as published: 210 Running: Additional kwh per month: 25.5 Additional electricity BDT per month: 184 Currency: BDT Publication year: 2026 Fx note: Source prints rounded USD pairs but does not disclose exchange rate used.

Zero added energy for passive scenario does not mean zero maintenance. Modelled cooling magnitude omitted; no safety certification or universal price.
  • Higher-specification home retrofit estimate Location: Dhaka-region worker homes, engineering scenarios Evidence status: reported Upfront: Materials BDT: 46100 Installation BDT: 15000 Total BDT: 61100 USD as published: 500 Running: Additional kwh per month: 40.5 Additional electricity BDT per month: 292 Currency: BDT Publication year: 2026 Fx note: Source prints rounded USD pairs but does not disclose exchange rate used.

Programmes

Who is working on it

Listing does not imply partnership, endorsement or ranking.

Overall

Known: Multiple distinct approved frameworks, primary heat research and real anticipatory funding/test mechanisms exist.
