Building Engineering or Architectural engineering, is a major of science that deals with engineering aspects in buildings, such as structure, construction, site management, mechanical, electric, lighting, acoustic, and energy efficiency. Building engineering is one of unique sciences that is strongly connected with all other types of engineering majors. In addition, it is connected to human basic life directly, and its application is able to noticed easily. However, this research will focus on the field of energy efficiency and opening construction in buildings. The reason why building energy conservation grab more researchers ‘attention is the fact of its relation with all other engineering aspects, and it is a building property that is very important along building life cycle. Currently humanity are living in world that energy market is biggest market in the world after weapons(Levy 2010). Nevertheless, energy in middle east is an important factor, especially when we know that country like Saudi Arabia, 75% of inside energy consumption goes to residential buildings(Of and Audits n.d.). And the reason why these buildings consume that much refers to high usage of energy in building applications, and leak of using eco-friendly building material that able to reduce energy consumption in buildings.

Abstract The situation of high energy consumption in construction industry is becoming increasingly severe, which hinders the sustainable development of world economy, society and environment. Building energy conservation reconstruction is urgent. The long-term and effective promote of buildings energy conservation reconstruction depends on the market development. However, its external characteristics and public goods attributes determine it is necessity of implementing incentives. The incentives of the buildings energy conservation reconstruction market development not limited in policy incentives, involving multiple influencing factors, which are interrelated and complex systems engineering. Therefore, it is necessary to integrate many factors into a coordinated dynamic system. This paper uses literature analysis method and expert interview method to identify the factors that affect incentives of buildings energy conservation reconstruction market development. In this study, the incentive structure frameworks of incentive elements, incentive operation, incentive efficiency and incentive environment were constructed by using the whole and part research idea. Based on principle of dynamic feedback analysis, Vensiem PLE was used to respectively analysis the four subsystem causality diagrams, the dynamic feedback relationship among the influencing factors in each incentive subsystem were clarified. The results demonstrate that incentive goal consistency, inspire all links, incentive system integrity and market maturity are the key factors affecting the incentive effect of the whole system. Finally, some optimization suggestions on incentive mechanism are put forward to promote the buildings energy conservation reconstruction market development.

Nowadays, people’s requirements for comfort are getting higher and higher, and traditional steady-state thermal comfort environment sometimes cannot meet people’s requirements. Dynamic thermal comfort is considered to meet people's requirements for comfort better than traditional thermal comfort, and it is also conducive to the health of occupants and building energy conservation. Therefore, this article reviews the literature on dynamic thermal comfort. First, this article briefly describes the transition from a steady-state thermal environment to a dynamic thermal environment. Next, this article reviews the research related to dynamic thermal comfort, such as the frequency of airflow fluctuations, simulation of natural wind, thermal prediction models, the use of intelligent detection equipment, and personal environmental control. This article summarizes the related research and development of dynamic thermal comfort from the aspects of dynamic airflow parameters, indoor thermal environment regulation, thermal experience, etc. This article aims to illustrate the necessity of the development of dynamic thermal comfort and its current results. The results show that under the trend of the artificial intelligence era, dynamic thermal comfort still has broad development potential. This article It can provide some research ideas for subsequent thermal comfort research. Practical application: This paper summarizes the research and development of dynamic thermal comfort from dynamic airflow, indoor thermal environment control, thermal experience, etc., and makes appropriate extensions and prospects accordingly. At the same time, the necessity of combining thermal comfort with AI trends is emphasized. This paper can provide references and ideas for thermal research on thermal comfort.
