Land Use as a Natural Conditioner of Environments

Abstract

In Argentina about 18% of the energy consumed is used for thermal conditioning of environments. A few meters from the surface, the soil temperature is very stable throughout the year, close to 19 ± 2°C (comfort temperature). With simple systems, it is possible to use this thermal reservoir to build a natural air conditioner, to reduce energy use and emissions of greenhouse gases, generating comfortable environments in both winter (heating) and summer (air conditioning). In this paper, we conducted an analysis of soil temperatures and a study in a real house with buried pipes, with satisfactory results and energy saving. The implementation of energy efficiency measures could reduce or even eliminate the need to import gas, industrial develop the country, create jobs and preserve natural resources.
