The building balance point temperature is the outdoor air temperature when the heat gains of the building are equal to the heat losses. [1] Internal heat sources due to electric lighting, mechanical equipment, body heat, and solar radiation may offset the need for additional heating although the outdoor temperature may be below the thermostat set-point temperature.
Extreme heat can be dangerous for runners, cyclists and outdoor enthusiasts: 6 tips for staying safe Susan Yeargin for The Conversation August 2, 2024 at 10:30 AM
Thermal fuses are usually found in heat-producing electrical appliances such as coffeemakers and hair dryers. They function as safety devices to disconnect the current to the heating element in case of a malfunction (such as a defective thermostat) that would otherwise allow the temperature to rise to dangerous levels, possibly starting a fire.
The SET index is defined as the equivalent dry bulb temperature of an isothermal environment at 50% relative humidity in which a subject, while wearing clothing standardized for activity concerned, would have the same heat stress (skin temperature) and thermoregulatory strain (skin wettedness) as in the actual test environment. [48]
Those include the heat index, which factors in humidity; wet bulb globe temperature, which is aimed at outdoors heat stress in the sun; and universal thermal climate index, which brings in ...
Forecasters are warning that there is a more dangerous aspect to heat waves these days: overnight temperatures are not cooling down enough Why nighttime heat can be so dangerous – and why it’s ...
Electric heating or resistance heating converts electricity directly to heat. Electric heat is often more expensive than heat produced by combustion appliances like natural gas, propane, and oil. Electric resistance heat can be provided by baseboard heaters, space heaters, radiant heaters, furnaces, wall heaters, or thermal storage systems.
Heating degree day (HDD) is a measurement designed to quantify the demand for energy needed to heat a building. HDD is derived from measurements of outside air temperature. The estimated average heating energy requirements for a given building at a specific location are considered to be directly proportional to the number of HDD at that location.
