Mahoney tables

The Mahoney tables are a set of reference tables used in architecture, used as a guide to climate-appropriate design. They are named after architect Carl Mahoney, who worked on them together with John Martin Evans, and Otto Königsberger. They were first published in 1971 by the United Nations Department of Economic and Social Affairs.

The concept developed by Mahoney (1968) in Nigeria provided the basis of the

Mahoney Tables, later developed by Koenigsberger, Mahoney and Evans (1970), published by the United Nations in English, French and Spanish, with large sections included in the widely distributed publication by Koenigsberger et al. (1978). The Mahoney Tables (Evans, 1999; Evans, 2001) proposed a climate analysis sequence that starts with the basic and widely available monthly climatic data of temperature, humidity and rainfall, such as that found in HMSO (1958) and Pearce and Smith (1990), or data published by national meteorological services, for example SMN (1995). Today, the data for most major cities can be downloaded directly from the Internet

The tables use readily available climate data and simple calculations to give design guidelines, in a manner similar to a spreadsheet, as opposed to detailed thermal analysis or simulation. There are six tables; four are used for entering climatic data, for comparison with the requirements for thermal comfort; and two for reading off appropriate design criteria. A rough outline of the table usage is:
