Abstract
In this paper a new kind of unit-prefabricated building is shown. The unit-prefabricated buildings are made up living unit, energy unit, water unit. The each unit was adapted new combine structure function as a high flexible design type. Moreover the design trend implemented the energy insulation, Solar PV panels, Energy storage system which are maintained for zero energy buildings. We made a prototype for zero energy flexible residential unit. The first step, we was evaluated physical performance and living environment, insulation, airtightness, thermal environmental, acoustic performance. The second step we was evaluated energy performance building to design heating and cooling system to combined PV, ESS system in the different plan type, and climate. As a results, The insulation performance wall was 0.18 W/(m2•K). The results of air-tightness was 12.13 ACH@50 (1/h). Further research we develop the structure and construction technology for zero energy flexible unit. To designed the high performance energy performance for zero energy building in the natural disaster.
Highlights
In recent years, the frequency of disaster occurrence has increased sharply around the world [1, 2]
When the pressure difference of 50 Pa is applied, the air leakage rate is (426 ± 6) m3/h and the airtightness performance of ACH@50 is 12.13 1/h. This result demonstrates that the airtightness performance of ACH@50, which is proposed in the performance and production standards of industrialized house, does not satisfy 1.5 1/h
For the current level mock-up modular house, the diagnosis was performed with respect to the airtightness, thermal insulation, and thermal bridge part, which are classified as building environmental performance factors of industrial house by the Ministry of Land, Infrastructure and Transport
Summary
The frequency of disaster occurrence has increased sharply around the world [1, 2]. On the other hand, when it is difficult to provide temporary housing, portable facilities like emergency tents and containers are used As another type of temporary housing, there is industrialized housing. It can be mass-produced and because it is easy to transport and simple to assemble owing to light materials, it has an advantage that a building structure can be constructed relatively . It can be utilized as a major solution for post-war urban recovery problem and housing problem. It is necessary to develop an infrastructureresponse type residence model whereby victims can reside and live temporarily when a disaster occurs, even if there is no infrastructure and no temporary house where victims can reside while feeling relieved
