Proximity to surface: the overlooked half of heating efficiency
Boilers and heat pumps make heat a long way from where it is used, and every metre of that journey costs energy. Why generating heat millimetres from the surface changes the arithmetic.

How clothing plays a role in the thermostat wars
A suit and a summer dress can differ by six degrees of comfort. What clo values are, why desert and arctic clothing look the way they do, and what it means for setting an office temperature.

Why do some people run hot and others cold?
Metabolism explains most of the office thermostat war. How basal metabolic rate, activity and body composition change the heat a person produces, and why one set temperature can never suit everyone.

Is far infrared heating safe?
Far infrared is non-ionising radiation at the long, low-energy end of the spectrum. Where it sits relative to UV and x-rays, what our films actually emit, and why surface temperature is the real safety question.

Air speed in the built environment
Too little air movement and you get mould and stale air; too much and you feel cold. Where the comfortable range sits, why draughts cost so much energy, and how heating choice changes both.

Why use carbon fibre to heat buildings?
Carbon fibre lets a heating element be a fraction of a millimetre thick, full-surface, perforable, non-combustible and unaffected by twenty years of heating cycles. Why the material decides the product.

Wind chill, a pleasant breeze, and severe dehydration
Air speed is a multiplier on heat exchange, and the same breeze can be a comfort or a danger depending on the temperature. Why wind chill does not actually make the air colder.

Understanding comfort: thermal neutrality explained
Comfort is not a temperature, it is a balance. The four routes your body loses heat by, the six variables that govern them, and why radiation is the one heating systems usually ignore.

Why 55 °C ceiling surface temperature?
Why a heated ceiling should run at about 55 °C. Emissivity, surface area and surface temperature under the Stefan–Boltzmann law, and where comfort sets the ceiling on temperature.
