project description

How can we give new life to over 800,000 buildings in Hungary? Koeb has developed a new solution for the modernization and renovation of the Hungarian building stock, primarily in suburban areas and rural settlements. Energy efficiency, environmentally friendly construction and residential use also play an important role in the project. The koeb modules can be added to already existing houses, they are an effective solution to increase the lifespan of homes, reach lower energy consumption, and contribute to improving the comfort and conscious energy use of population. The build-in home refurbishment system consists of fully functional housing elements, such as Mechanical, Bathroom Module and the Sunspace. Prefabricated modules can be easily connected to existing one-storey residential buildings. For this reason, the tent-roofed cubic ó houses were given a prominent place in the project, also known as Kádár-cube in Hungary, of which over 800,000 are today. Koeb can respond to a real ó problem with technology and creativity. The prototypes can be viewed at this year’s exhibition in the koeb house.

key features

The koeb project examines modernization from the aspects of environment and society. From an environmental point of view, connecting a koeb mechanical module to an existing property results in an annual positive energy balance, optimal for real estate and residents, with the contribution of solar panels, a high share of green energy and battery power storage. The energy features are improved by additional passive and active solutions, such as a mass wall or an efficient heat pump system that meets the residents’ temperature and water ó needs. The aim of the life cycle analysis of every built-in material and system is to monitor how the smallest possible ecological footprint can be reached. Koeb can be a system that contributes to several technological and sustainability benefits for creating forward-thinking areas.

applied innovative technologies

Some of the engineering solutions to mention: energy consumption and storage coordinated by building automation, supplemented with production forecasting, gabion wall with active ventilation in the interior of the module, solar system integrated in green roof, deciduous green facade for improvement of winter and summer energetics. The main objectives of the project are to improve the conditions of the Hungarian housing stock in economic, environmental and social terms. In addition to architectural innovations, the Team pays special attention to harmonizing the three pillars of sustainability with energy efficiency. The project focuses on building a sustainable energy community, whether it is a street or a network of settlements.
