jailcd2019-004: Dynamic Simulation Verification of Low Carbon Energy-Efficient Building Based on DeST - Taking the Eco-house Kitakyushu as an Example

Abstract

Under the Kyoto Protocol, Japan is committed to the international task of energy conservation and emission reduction. In the process of exploration, the perspective gradually turned to the energy-saving and emission- reduction design of residential buildings, and the Kitakyushu Ecological House came into being. Eco-houses are designed to take advantage of new energy and new technologies to achieve the goal of more efficient use of energy and energy conservation, and to reduce greenhouse gas emissions. However, whether the actual operation conditions are expected to be designed as expected is still to be verified. Computer simulation is an effective tool for predicting building performance under various conditions and for providing a theoretical basis for retrofits that provide cost-effective energy savings. Eco-house Kitakyushu was investigated using the Designer's  Simulation Toolkit  (DeST).This paper  focuses  on the measurement  of the thermal  insulation properties of the Eco-house  enveloping materials and uses the DeST to conduct a hour-by-hour dynamic simulation comparison to verify the rationality of the ecological housing design and provide reference for the future development of ecological housing.
