Why now
Heat is now an everyday workplace risk
Europe is the fastest-warming continent, and 2024 was its warmest year on record. Work, plant and stock feel it first, often before a thermostat does.
workers likely exposed to excessive heat during their work: 70.9% of the global workforce.
ILO, 2024occupational injuries a year attributable to excessive heat.
ILO, 2024work-related deaths a year attributable to excessive heat.
ILO, 2024Europe's warmest year on record, on the fastest-warming continent.
C3S & WMO, 2025-
Heat strain on people and work
Radiant heat, dark roofs and physical work push strain up before thermostats trigger.
-
Cooling load and energy pressure
Chillers run flat out fighting avoidable solar gain, driving up peak electricity demand.
-
Asset and stock degradation
Thermal load trips switchgear and threatens temperature-sensitive goods in storage.

Heat twin: your site's own heat-risk model, kept current with the forecast
The same 15 answers and the same scoring as the self-check, plus your site's location. When a heat episode is forecast near your site, the twin flags it, shows how many days you have, and re-dates your 30-day plan.
Finish the self-check above to run the twin on your own answers. They stay in this browser tab.
Demo only: the three forecasts are synthetic examples, not real weather data, and the sites are fictional. Day 1 is shown as 1 July. The scores and dates come from the same fixed rules the heat twin will use. Follow official weather warnings on the day.
- Built from your self-checkThe same 15 answers and the same scoring as the self-check, plus your site's location.
- Watches the 15-day forecastWhen a heat episode is forecast near your site, the twin flags it and shows how many days you have.
- A dated plan that moves with the weatherActions you can still take before the heat move forward. Building measures wait until after it.
- Email digest and a private dashboardOnly when something changes. No account to manage, and never personal health data.
How the twin decides: the published rules
Every forecast day is classed by its maximum and minimum temperature:
- Heat episode: 3 or more warm days in a row including at least one hot day, or a hot day with a tropical night.
- Forecast points: up to 15, larger when the site already has cooling, people or preparedness gaps. They are shown next to the base score, never mixed into it.
min(15, round((2·days + 3·hot days + 2·tropical nights) · (0.5 + 0.5·sensitivity))) - Re-dated plan: quick actions (service, heat plan, shading, work, monitoring) are due the day before the heat starts; heat-day steps are placed on each episode day; building measures (roof, glazing, envelope, location) move to after the episode.
- Confidence: an episode starting 7 or more days ahead is shown as “possible (may change)”; nearer ones as “expected”.
Where the forecast comes from
The heat twin is designed to use ECMWF Open Data: the 15-day forecast of the European Centre for Medium-Range Weather Forecasts, published under a CC BY 4.0 licence. The twin reads the nearest grid point (about 25 km) to your site and reduces it to daily maximum and minimum temperatures. It works for any location in the world, in °C, and is not an official forecast or warning. The demo above uses synthetic forecasts, not ECMWF data.
What “AI” honestly means here
The scores and the plan are calculated by fixed, published rules from your answers and the forecast. No machine-learning model decides anything. An optional AI-written plain-language summary may be offered later: off by default, labelled “AI-written”, and never allowed to change a score or a date.
Scores sites, not people. Not engineering, legal or health advice.
Order of measures · Cooling Trias
The 4-step heat hierarchy
Sizing mechanical cooling before reducing heat gains locks a facility into higher peak electricity loads and faster equipment wear.1 Work through the steps in order.
- 1Block solar gain before it crosses the roof or glass.
- 2Contain internal heat at the source.
- 3Flush and cool efficiently, sized for the reduced load.
- 4Sense, plan and protect people with clear triggers.
Keep solar radiation outside the envelope first
A dark bitumen, EPDM or metal roof gets very hot in summer sun, radiating heat down into top floors and mezzanines while accelerating membrane ageing. Similarly, unshaded south and west glazing admits direct short-wave solar radiation that traps heat indoors.
- Cool-roof coatings and light membranes: high solar reflectance and thermal emittance reduce peak roof surface temperature.
- External solar shading: screens, brise-soleil, louvres and overhangs stop solar gain before it crosses the glazing (Arbobesluit art. 6.4).
- Solar-control glazing and films: lower total solar energy transmittance (g-value) on existing façades and rooflights.
- Site microclimate: unpaving, green or blue-green roofs and tree shade around paved industrial yards (Klimaateffectatlas hotspots).
Contain heat at the source before it enters the work zone
In manufacturing, food processing, laundries, boiler rooms and data halls, bare valves, flanges, steam pipes, ovens and compressors radiate heat directly at workers and into the conditioned volume. Cooling the entire hall with HVAC to offset uninsulated pipes is the most expensive way to manage process heat.
- Removable insulation jackets: custom-fitted thermal jackets on valves, flanges, heat exchangers and actuators that maintenance teams can unfasten and refit.
- Radiant heat barriers and shielding: reflective partitions between furnaces or ovens and operator stations to cut mean radiant temperature.
- Local hood extraction and zoning: capturing convective plumes and moisture right above the machine and isolating hot equipment rooms.
Flush heat at night and size active cooling for the reduced load
Multi-day heatwaves build thermal mass temperature day after day if heat cannot escape overnight. Once solar and process gains are reduced, ventilation and mechanical cooling can work reliably without tripping on peak afternoons.
- Night purge and free cooling: automated night or early-morning ventilation to flush accumulated heat from the building structure when outdoor air is cool.
- Targeted zone cooling and air movement: spot cooling or elevated air velocity at occupied workstations rather than conditioning empty high-bay roof voids.
- Pre-summer commissioning: scheduled spring checks of refrigerant charge, condenser coils, filters, dampers and control setpoints.
Measure where heat actually bites and act on clear triggers
Standard room thermostats are mounted on shaded interior walls at 1.5 m height, not on top-floor picking mezzanines, near glazing, or beside hot plant. Without zone logging and a written heat plan, teams improvise under pressure on the hottest day of the year.
- Continuous zone logging and WBGT: simple open-export loggers in the 3–5 hottest zones, plus Wet-Bulb Globe Temperature (ISO 7243) where radiant heat or humidity is high.
- Written heat plan with triggers: pre-agreed actions tied to indoor temperature thresholds and KNMI / RIVM Nationaal Hitteplan warnings.
- Arbowet and RI&E integration: documented work/rest schedules, shaded rest areas, chilled water, and early protection for heat-sensitive staff or visitors.

Independence
How we earn, and our independence pledge
You pay Humanity Solutions for the Heat-Risk Readiness Report (€147.93 excl. VAT), or for site-specific advisory work we agree and quote in writing before starting. We do not sell or install products.
- No rankings for saleNo product rankings, paid placements or sponsored answers in the self-check, report or twin.
- Fees disclosed firstIf a vendor may pay us a referral fee, we tell you in writing before you decide.
- At least two optionsWhere more than one suitable option exists, we show you at least two.
- Never added to your quoteVendors warrant that a referral fee is never added to your price (most-favoured pricing).
Supplier introductions
If you later ask us to introduce you to a supplier and you choose to buy from that supplier, the vendor may pay us a referral fee. Under our standard vendor referral terms (PDF), vendors warrant that the referral fee is never added to your quote (most-favoured pricing). We always disclose any referral fee to you before you decide, we show at least two options where they exist, and our advice never depends on who pays us.
Six technical areas we examine across sites
- Thermal coatings. Cool-roof and reflective barrier coatings timed with roof maintenance.
- Insulation. Roof and wall envelope upgrades and EN ISO 12241 removable jackets on hot pipes, valves and plant.
- Architectural measures. External solar shading, brise-soleil, louvres, rooflight shading and solar-control glazing film.
- HVAC, night purge and active cooling. Free night cooling, zoning, spring commissioning and right-sized cooling plant.
- Monitoring and sensing. Open-export temperature loggers, WBGT work-zone sensing (ISO 7243) and thermal imaging surveys.
- People and planning. Written heat plans with KNMI or temperature triggers, work-rest schedules and Arbowet / RI&E input.
Do you sell or install cooling or coating products?
No. We help you diagnose your heat exposure, prioritise passive and operational measures first, and know what to ask suppliers. Independent vendors supply and install.
How do you earn money?
You pay for the Heat-Risk Readiness Report (€147.93 excl. VAT) or for advisory work we quote in writing. If you choose a vendor through our introduction, that vendor may pay us a referral fee. We tell you in writing before you decide, and our contract with vendors prohibits them from marking up your price.
What is a heat twin, and when is it available?
A heat twin is a small model of one site's heat risk that stays current: your 15 self-check answers, your site's location, and the 15-day weather forecast for that spot. When a heat episode is forecast, it flags it and re-dates your 30-day plan, with an email only when something changes. It is in development and will start with a small pilot. Try the demo or ask to be notified.
Is the heat twin “AI”?
The scores, dates and plan come from fixed, published rules, not from machine learning, and the base score never changes with the weather. An optional AI-written plain-language summary may be offered later; it will be off by default, clearly labelled, and never changes a score or a date.
Does it work outside the Netherlands?
The heat twin is designed to be country-neutral: any location, temperatures in °C, and no country-specific legal text in its output. The self-check and the paid report also list Dutch employer duties (Arbowet), because that is where we started.
Why are there no cost savings or ROI percentages in the self-check or report?
Because generic payback percentages from a 15-question questionnaire would be guesswork. Energy savings and temperature drops depend on your exact roof build-up, internal loads, local weather, ventilation rates and tariff structure. Instead of invented numbers, we give you a transparent score, a 30-day action plan, and the exact technical questions to ask installers and engineers.
Is the self-check or report engineering, legal or health advice?
No. Both are structured diagnostic tools based on public guidance (RIVM, KNMI, Klimaateffectatlas, EU-OSHA, ISO 7243, Arbowet). They score sites, not individuals, and do not replace a site inspection by a structural or HVAC engineer, occupational hygienist (arbodienst) or legal counsel.
