Weather and solar data: A review of information in the CIBS Guide Section A2 (1982)

Abstract

A review is made of the weather and solar data in Section A2 (1982) of the CIBS Guide, resulting from the greater availability of information since the 1970 (IHVE) Guide was written and of the development of computer-based analytical techniques whereby coincident weather parameters can be conveniently studied. UK cold and warm weather data, wind and precipitation are summarised. Daylight availability is much better understood as the result of a new analysis applied to more recent measurements of diffuse (sky) illuminances. The principles adopted to analyse ‘coincident weather’ are discussed. These have led to new “design maxima” of solar irradiances for SE England together with their coincident dry-bulb temperatures. Monthly weather data for Kew have been divided into ten bands' for use where a thermal computer program cannot handle weather tapes. The simulation of hourly solar irradiances using newly-introduced direct and diffuse radiation factors is described. Revised sol-air temperatures reflect a slightly different treatment of long-wave loss' and radiation maps give the availability of solar energy over the UK.
