На позив мог професора са Машинског факултета Универзитета у Београду и дугогодишњег председника Друштва КГХ (климатизација, грејање и хлађење) Србије проф. др Бранислава Тодоровића, дао сам интервју на српском језику за последњи број стручног часописа КГХ (2-2023). Разговор је био првенствено о мом професионалном раду, о учешћима на конгресима о КГХ и понешто о мом личном животу.
Електронска верзија овог интервјуа доступна је линку архиве часописа КГХ на веб-сајту СМЕИТС-а.
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 selection for the presentations of the “architecture of the future” on the Future Architecture platform is underway. I applied for this competition with my idea of a type of house that represents a new green technology with roots in prehistory (so-called neolepenism). Applications have been sent from all over the world and 25 ideas will be selected to be presented, including one by the audience. You can vote on the link bellow, if you like this idea, by clicking the “I like it” button at the end of page. The post can be shared on some social networks, and below the voting button there is a link where you can see other submitted ideas, for those who are interested. Voting lasts until noon UTC on January 14th.

This paper was published 31.08.2020. in REHVA Journal. REHVA is a HVAC association that develops and promotes energy efficient, safe and healthy technology for mechanical services of building. REHVA is the Federation of European Heating, Ventilation and Air Conditioning Associations, representing a network of more than 100.000 engineers from over 25 countries. Since 1963, the association is dedicated to the improvement of health, comfort and energy efficiency in all buildings and communities by facilitating knowledge exchange, supporting the development of related EU policies, and their national level implementation.
Space design can be one of the strategies for designing low-energy and passive houses and buildings. Neolepenism is a new, internationally copyrighted type of energy efficient architecture with roots in the prehistoric culture of Lepenski Vir (Serbia). The author has previously presented the model of a small family house of neolepenism with a flat roof at 50th Congress and Exhibition of KGH in Belgrade in 2019 and wrote about the energy efficiency of the prehistoric architecture of Lepenski Vir, whose positive experiences he improved and optimized. This new industrial design could significantly contribute to the reduction of heat losses (in winter) or gains (during the summer season), reducing greenhouse gas emissions and saving building materials and thermal insulation, primarily by its compact shape, and to a lesser extent by utilization favorable orientation, by digging in earth, application of green roofs and aerodynamic shape. In this way, neolepenism could have a positive impact on global warming and climate change as a passive means of protection.
The author of Neolepenism house visited the Museum Lepenski Vir on the Friday, 28th of August 2020. Here is a short presentation of the model of Neolepenism house at the archeological site, which was the model for this new energy efficient architecture. Neolepenism house architecture can respond to challenges of Climate changes and Global warming.
Nenad Miloradovic has entered in the online Ancient history encyclopedia which was rewarded by EU in 2016. His paper from REHVA Journal “Lepenski Vir – the prehistoric energy efficient architecture” is in bibliography and some terms are quoted in the article about Lepenski Vir by Andela Sormaz. This post was published on 5. May 2020.
As a member of ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) Nenad B. Miloradovic had presentations within the Danube Chapter in Timisoara, Romania, from 2016 to 2018. All of these presentations were directly or indirectly related to Neolepenism. The outline from the first presentation was published in the REHVA Journal in October 2016. That year was the first international presentation of this topic. Because of that, the author of Neolepenism is very grateful to Professors Branislav and Marija Todorovic from KGH Society, Mr. Ioan Silviu Dobosi of the ASHRAE Danube Chapter and Mr. Jaap Hogeling, the editor of the REHVA Journal, who were also attended the presentation.

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.
