The change in climate and the rise in energy rates have become a necessary consideration in the construction industry which has made architects and engineers to arise with improved building design concepts. A focus on creating a comfortable indoor climate in office buildings ensures productive working conditions for the users and reduces global warming. Specific climatic design principles are often disregarded when designing to create a comfortable indoor climate. Sustainable design methods in buildings has been replicated from one zone to another zone without adjustments which results to buildings that do not provide adequate comfort. Capillary tube system is used to provide a comfortable indoor climate for office buildings making an interesting use of geothermal energy. This paper aims to explain its principle using geothermal energy and the effect of climate on the use of this system in office buildings in Africa. A case study of Lagos state lying on the coast of the Atlantic Ocean which is challenged with high rise in sea level as a result of global warming in Nigeria and Windhoek in Namibia is to be taken into consideration as the business hub of its country. These regions comprises of many office buildings to facilitate the countries trade internationally and locally.
