TOPS 2021

Conference TOPS 2021, Zlatibor, Serbia, 18.6.2021.

Poslovno udruženje toplana Srbije TOPS održalo je 19. susrete toplana Srbije u okviru kojih je bila naučno-stručna konferencija TOPS 2021. Mesto održavanja konfrencije je bio hotel “Palisad” na Zlatiboru, Srbija. Konferencija je održana 18.6.2021. Na toj konferenciji, čija je glavna tema bila dekarbonizacija, predstavio je svoju prezentaciju Nenad B. Miloradović kao predstavnik JKP “Beogradske elektrane”. Tema njegove prezentacije je “Solarno daljinsko grejanje i arhitektura neolepenizma – sprega za uspešnu dekarbonizaciju”.

How to easiest construct Neolepenism basis?

You should start with construction of regular pentagon

This link shows how to this!

After this is easy. Than, you just need to add four edges of regular decagon. That’s it!

This construction is very similar with first optimized and calculated Neolepenism basis and it’s with similar performances. Instead of edges of decagon you may apply the arc.

In this way, the Neolepenism basis is strongly connect with Golden ratio or Golden angle (137,51 degree) which is applied in the Nature and the architecture.

This shape can use Sun radiation (light and heat) in the most effective way.




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.

By Nenad B. Miloradović in REHVA Journal Vol. 57, 04/2020

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.

Neolepenism as mathematical architecture

Neolepenism is a distinctly mathematical architecture. It is based on adaptation of the building to the natural environment, which involves fitting into the geographical, climatic and plant environment and taking into account the impact of solar radiation. This kind of architecture, though new, has deep roots – a practice that was implemented over a long period of time, about 8,000 years ago.

For the architecture of Lepenski Vir, which is a model and inspiration for the new architectural forms proposed in this website, the archaeologist D. Srejović claimed that he had something very mathematical in this. He meant primarily the geometric shape of the base, but at the same time noticed the connection of architecture with the natural environment, that is, with the ambient.

Dragoslav Srejovic wrote in his book about Lepenski Vir: “Due to the marked ‘unhistoriness’ of the architecture of Lepenski Vir, we are tempted to explain the exceptional nature of its forms by specific features of the terrain and space, ie. natural environment. The connection between architecture and ambience is really obvious. (…) The architecture of Lepenski Vir has in itself something extremely mathematical, that is, in its entire forms one can feel the presence of concrete longer and certain numbers. (…) The structure of Lepenski Vir I and Lepenski Vir II (…) corresponds only to the morphology of the city of the distant future. (…) The architecture of Lepenski Vir merely ‘reads’ its surroundings, translates its intricate, condensed contents into an easily understood language…”.

The terms Neolepenism (neolepenizam) or Neolepenism house (kuća neolepenizma)

We use a lot of words for energy efficient house: passive house, green house, low energy house, NZEB, Energy plus house…

Neolepenism can be a new kind of energy efficient architecture that can respond the challenges of sustainable development. The name Neolepenism is very appropriate because the prefix neo denotes something new, while Lepenism refers to the architecture of the prehistoric settlement and culture of Lepenski Vir. The Lepenski Vir is located on the right bank of the Danube in the Djerdap Gorge (Republic of Serbia). The architecture of this prehistoric settlement has served as an inspiration and role model for a new, copyrighted form of building that is based on the principles of energy efficiency.

The term Neolepenism for this form of architecture was proposed by Serbian actor and former student of the Faculty of Mechanical Engineering in Belgrade, Predrag Kolarević, when he saw animations of a building with the this form. This term is not in any way related to the terms “Lepenism” and “Lepenization” encountered on the Internet, which are related to the politics of French politician Jean-Marie Le Pen.
