The Economic Demands on the Method of Founding a Passive Brick House on Foamed Glass Granulate

The cost of acquisition of a passive house is a little higher than that of a conventional house.Proper design of a passive house should include not only thermal protection and stability of the construction,but it must also take into account the price demands on each of the proposed structures and solution of details.The paper deals with the financial comparison of the traditional method of a foundation on the foundation strips of plain concrete and the modern method of founding a passive house as brick construction on the reinforced concrete slab base with a compact subsoil layer of thermal insulation in the form of granules of foamed glass.

A Study of Passive Solar House Design

This paper deals with the investigation of the principles of passive solar house design, passive solar systems, and techniques for solar house design. It is expected that the research is to be of momentous significance to the design and construction of passive solar house, and may make contribution to the massive energy efficient housing construction in our country.

Primary Exploration of the Feasibility of Passive Houses in Korea and China

The transferability of European experiences with design,planning,construction and service of Passive-Houses to the specific conditions in China and Korea is investigated by the adaptation of the PassiveHouse principle to typical Korean and Chinese residential building,by the use of locally available building materials,components and building practices as well as under consideration of specific and typical ways of living in the two countries and cultures. The starting basis for the research is the analysis and evaluation of specific climate conditions,architecture,building practice as well as specific comfort criteria. The additional effort for the construction and service of Passive-Houses in Korea and China compared with typical contemporary residential buildings is investigated on the basis of a comparison of designs for Passive-Houses and for common buildings,including issues like the heating and cooling energy demand,heat and cool load as well as the required materials and components. The research results show that the described modifications of typical contemporary residential building constructions in China and Korea are realizable with locally available materials and feasible effort. They can reduce the energy demand for the service of domestic housing significantly and are in the range of European Passive Houses.

Lecablock, an Alternative Construction Material for the Exterior Walls of Passive House

In this paper it is attempted to investigate the Leca blocks as sustainable construction material for the exterior walls of passive house. The building physical properties of Leca design wall structure are studied along with the environmental impact and load-bearing capacity. To compare the results, a similar analysis is carried out considering the traditional wooden wall construction of passive houses. The results showed that Leca design wall structure can be an alternative sustainable solution to the traditional wooden wall structure of passive house, mainly due to its low U-value, its ability to handle moisture, and comparable structural load-bearing capacity. However, the wooden wall structure is more environmentally friendly than the Leca blocks due to its lower emissions to the environment and reduced energy use, especially during the manufacturing process.
