Abstract
The analysis and modeling of unconventional thermal zones is a first step for the inclusion of low-cost spaces and for the assessment of the environmental impact among areas of human use in warm climates. In this paper, the heat transfer in a geodesic dome located at the University of Magdalena (Colombia) is modeled and simulated. The simulator is calibrated against experimental measurements and used to study the effect of different loads which are regulated by a controller in sliding modes explicitly designed for this case. The closed-loop system is used together with ASHRAE Standard 55 to characterize comfort conditions within the dome and the effect on the overall thermal sensation with increasing the number of occupants.

Summary
In the last few decades, the world population has continued growing exponentially. In only 15 years, it increased from 5300 to 7300 million inhabitants, according to the reports of the United Nations. A new strategy to reduce the energy consumption for refrigeration is the reuse of ancient techniques, such as green walls and roof domes among others Using these structures, the internal temperature of buildings decreases substantially without using heating, ventilation, and air conditioning (HVAC) systems. Domed roofs are widely used in Middle Eastern countries such as Iran and Turkey [1,2] These kinds of buildings use the air flux and stratification phenomena to reduce the internal temperature. This paper presents a mathematical model for a geodesic dome built with the lumped parameter technique. This method introduces new circuit schemes to model non-conventional thermal zones [13].
