Worked cases
Eighteen buildings, each modelled from a published prototype or a real product, each run against its own typical meteorological year, each one open to inspection — the machines are published systems you can load, the building runs on every plan including Free. The numbers are readings of the model, not brochure figures; where a case leaves something open, the page says so.
The badge says fifteen kilowatts. In January it is nine
Berlin
Four flats on radiators and one air-to-water heat pump: sized on the rating it leaves the corner flats cold, and the flow temperature it runs at is a fifth of its running cost.
One machine, four rooms, and the hour it can only do one thing
Tokyo
A 20 HP outdoor unit and four 14 kW indoor units on one pair of refrigerant lines: about 26 kWh/m² a year for cooling and heating both, and a two-pipe limitation that shows on winter mornings once the glazing knows which way it faces.
A cleanroom that dries by its damper, not its heater
Taipei
An ISO 7 room at twenty air changes on a recirculating handler: 494 MWh of electricity a year with electric reheat, 150 with face-and-bypass — and the makeup-air unit that was supposed to fix it, built, measured and declined.
A supermarket floor dried at the door, and a freezer held at −20 °C
Houston
Display cases as a negative gain, three gas rooftops, a dedicated outside-air unit that takes the sales floor's hours over its humidity ceiling from 1 391 to 0 for less energy than the rooftops spend missing it, and a frozen store on a remote low-temperature condensing unit.
A district plant serving three buildings through a manifold
New York
Four Copeland scroll maps on R513A as a 600 kW-class centrifugal stand-in, unloading on a real centrifugal's curve, a rated cooling tower, a 6.5 °C loop to a library, a lecture hall and a laboratory — and 132 MWh of boiler-fired reheat holding three humidity ceilings on the bound.
Two operating theatres held between 30 and 60 % RH in Helsinki
Helsinki
A steam humidifier steered to a room humidity floor, 40 % outside air with no economiser, a 120 kW preheat, and a recovery ward on a fan coil with heat of its own.
An office floor on one packaged VAV rooftop
Chicago
The DOE Medium Office plan — four perimeter zones and a core — on a 90.1 System 5 rooftop with boxes, an economiser, demand-controlled ventilation and a supply fan holding duct static.
A mall where two machines feed each other, one hour behind
London
Five rooms, a chilled-water VAV air handler fed by an air-cooled modular chiller drawn as its own block, a DX split, and a dedicated outside-air unit leading the screening room.
An edge data centre on a warm loop
Singapore
Two data halls on a chilled-water CRAH fed by a chiller holding 13 °C, a UPS room on a remote condensing unit and an indoor DX unit, and a staffed NOC on a split — held on Singapore's year.
Three fan-coil wings and a lobby on one chiller, through a manifold
Miami
Guest rooms on the DOE Small Hotel rhythm — full at night, out by day — on two-pipe fan coils, a lobby on an outside-air unit that carries the latent plus a fan coil of its own, five receivers on one chiller.
A primary school that burns gas and pumps heat
Toronto
Classroom wings on reversible DX splits — frost derate and all — and a gym on a packaged rooftop with a gas furnace: the first example that burns gas, and what a heat pump does at −20 °C.
A logistics hall cooled by water in a dry climate
Phoenix
Three two-stage evaporative units — an indirect stage ahead of a direct pad — leading a 2 000 m² hall, with a gas rooftop behind them for winter nights and the hottest afternoons' trim.
A telecom shelter where the economiser is the machine
Denver
A 20 m² equipment room with 3 kW of radios around the clock on one split; the winter week's coil duty is under 5 % of the summer's, on less electricity.
The waiting room is cold because the consulting room is hot
Denver
Four rooms on one three-pipe VRF: on 546 hours a year the glazed south suites shed sun while the north waiting rooms ask for heat, and moving that heat sideways is 1 900 kWh and 372 hours of waiting.
The hall is heated by the water it evaporates
London
A public pool hall on a heat-pump dehumidifier with a reclaim condenser: 550 tonnes of water leave the pool as vapour a year, and nineteen-twentieths of the heat that took goes back into the water before the rest reheats the hall.
The server hall is the boiler
Seattle
An edge data centre's 18 °C cooling return, lifted to 54 °C for the offices next door by a water-source heat pump: seasonal COP 7.3 against 3.1 on outside air, the chiller makes 13 % less, and the site runs on 13 % less electricity.
The dryer that keeps its heat
Buôn Ma Thuột
A closed-loop heat-pump coffee dryer on a digital scroll rated to 85 °C condensing, run on the chamber's humidity alone: 0.62 kWh per kilogram of water against 2.04 for the hot-air dryer venting the same chamber, on under a third of the batch's electricity.
Forty-five kilowatts of servers, a tank of oil, and a small cooling tower
Frankfurt
An immersion cooling hall with nothing but water between the servers and the weather: a 45 kW tank coupled to a small evaporative cooler holding 32 °C, and the year's cooling electricity read against the IT load.
Every figure comes from measure_examples_on_their_years on the day the case was written and moves when the model does; the history of every reading is kept with the code. Results are engineering estimates from catalog data and published correlations.
