This paper presents the case study of the authors’ design of the earth-sheltered house in Village Dobraca near Kragujevac, Serbia, in the context of development and some thermal properties of the underground housing. The historical insight, in brief, provides a better understanding of the reasons for their modern use as energy efficient and sustainable structures. It shows that underground houses even today are more thermally efficient than above ground houses since, besides earth, there is no need for new additional thermal layers. The article also includes a review of the representative physical forms of the underground housing through different periods, with the result of measurement of their main properties. The study of the underground housing structures provides an insight of the relation between the location and typology of underground homes in a contest of climate zones. These structures have an almost constant temperature, which provides the primary “comfort” condition in which the man is determined to live in. The results on property-based monitoring data showed that the earth-sheltered house could provide the thermal comfort that is close to the ideal human needs temperature. Today, the new materials and especially the solar, geothermal, and wind accessories, enables the maximum sustainability of these specific building structures and provides them with an even better energy efficiency.

The prehistoric settlement of Lepenski Vir, which was discovered during the 1960s in Djerdap Gorge on the Serbian side of the Danube River, is well-known for its unusual architecture and preserved house floors. If we analyze this architecture in view of the set of natural (meteorological, geographical, astronomical and vegetal) environmental properties and consider energy consumption for heating and air-conditioning needs for such dwellings, i.e. achieving thermal comfort in those houses, we can conclude that the builders paid particular attention to energy efficiency in building stock while designing those houses. Remains of the architecture of the prehistoric settlement of Lepenski Vir, where operations for energy efficiency improvements are visible and recognizable, are the remains of an energy effective architecture. Their houses were energy efficient considering their age, technology and given location, contributing to the long life of the settlement.
We may speak about the primal passive solar and bioclimatic architecture. The shape of houses is very compact and contributes to saving of heating or cooling energy. The remains of the architecture of Lepenski Vir are silent witnesses of measures applied to improve energy efficiency. The houses in Lepenski Vir and Padina-Gospodjin Vir are examples of energy efficient construction of the time, location and given the condition of technology and applied materials. The architecture of Lepenski Vir did not emerge haphazardly, as similar house remains were also found at the Padina-Gospodjin Vir site.
