Abstract
One of the new approaches in civil engineering is geodetic domed houses. These are quite economical buildings that most fully reflect the idea of energy saving and the concept of environmentally friendly housing.
 The symmetry of the sphere allows the most efficient placement of solar panels and solar collectors. The structures of the house are assembled quickly and do not require heavy construction equipment. By reducing the volume of the heating room, we save on heat resources, so the heating of the domed house in the winter requires 20 – 30% less energy in comparison to the rectangular buildings.
 The purpose of the article is to offer solutions for the development of projects of energy-efficient geo-houses in Ukraine. To search for the most rational design and technological solutions; to analyze the characteristics, advantages and disadvantages of energy efficient geo-house buildings in order to build them in Ukraine.
 The geodesic dome is made of polyurethane foam, reinforced concrete, wood, fiberglass concrete. Frame structures of the geo-house are made of metal or timber, the "skeleton" is lined with plywood or special OSB-boards. This method provides lightness and strength of the building. The dome must have the optimal size of the ribs, not more than 2.5 m in length, which allows you to erect a frame without the use of technology, with a force of 2 ÷ 3 people. Two installation methods of the frame are considered: connector and non-connector.
 The proposed solutions for the development of energy-efficient geo-houses' projects in Ukraine will allow in the near future to solve the problems of ecology, energy saving, natural resources saving in the country. Energy-efficient geo-house is the best option for any region of Ukraine, thanks to the undeniable advantages: rigidity and stability of the frame, geometric symmetry of shapes and strength, energy efficiency, high seismic stability, erection speed and originality.

Висновки (Conclusions) Запропоновані рішення із розроблення проєктів енергоефективних геобудинків в Україні, дозволять в найближчому майбутньому вирішити проблеми екології, енергозбереження, економії природних ресурсів в країні
Summary
Які найбільш повно відображають ідею енергозбереження та концепцію екологічно чистого житла. Провести пошук найбільш раціональних конструктивно-технологічних рішень; проаналізувати характеристики, переваги та недоліки енергоефективних геобудинків з метою зведення їх в Україні. Купол повинен мати оптимальний розмір ребер, не більше 2,5 м в довжину, що дозволяє змонтувати каркас без застосування техніки, силами 2 ÷ 3 чоловік.
