CLIMATIC VARIABILITY, CLIMATIC CHANGE AND THE THERMAL PERFORMANCE OF BUILDINGS
The building designer has a number of simplified methods at his disposal when investigating the thermal performance of a proposed building. In reality however, the process of interaction between external climate and a building structure is exceedingly complex and only with the advent of powerful computers has the realistic modelling of thermal performance become feasible.
Using measured climatic data and a computer calculation technique, the thermal performance of typical Australian dwellings has been examined for the locations of Melbourne (a temperate climate) and Port Moresby (a tropical humid climate). Six years of data were used for Melbourne, four years for Port Moresby and hourly indoor temperatures or loads were calculated over those periods.
Examination of the results indicates the effects of so-called “typical” climate on building thermal performance and suggests also the possible effects of longer-term climatic change.
Among significant conclusions are that typical thermal performance variability depends largely on time of year for regions with a temperate climate, while in the longer term, a decrease of mean temperatures by 0.5–1°C could lead to increases in heating fuel consumption by up to 20% if present comfort standards are to be maintained.
The effects of long-term climatic changes have perhaps been underrated. An examination of the various forms of indigenous or traditional building highlights the extent to which building design has, in the past, been influenced by prevailing climate.
