Subtropical Region

Because of the relatively small number of the subtropical region building energy research, resulting in the construction of energy-saving measures in the area of building energy method is mainly imitate other regions. The building energy efficiency should be appropriate. And the crucial of the building energy efficiency in subtropical region is heat insulation processing. This paper presents the idea of a subtropical region suitable for natural ventilation insulated exterior wall structure. A new kind of suitable natural ventilation and heat insulation building structure for exterior wall in hot summer and warm winter area is proposed in this paper, which thermal properties is calculated by Maple software. And this paper demonstrates that this kind of structure is the feasibility of the structure. The result of the comparison of thermal properties of different insulating structure by using the finite difference method for unsteady heat conduction calculation presents that the insulation performance of the buildings which have the natural ventilation and heat insulation structure is better than the ones without this ventilation. In the end of paper, the authors descript the hope that this kind of structure will be further research and analysis.

The Government

The constraints of resources and environment in China are more and more intense. The 12th Five-Year Plan requires that energy saving must be considered in the architectural design. Liangshan has special climate and sunshine. Therefore, the Government of Liangshan requires that building energy saving must be started from the stage of architectural design. Building energy efficiency must be considered from several aspects, such as architectural layout, wall structure, windows and doors, roof structure, external sun-shading, and construction materials.

Building Energy Efficiency is one of the most important goals for green architectural design. Natural ventilation is a building energy efficiency technique adapting to the environment. Compared with air conditioning, natural ventilation can reduce the energy consumption and bring new air to indoor space. However, air environment, as an important aspect of building optimal design, can be ignored easily in traditional research, the quantitative analysis aiming at the energy efficiency of natural ventilation is less. In this paper, we use Fluent Air-pak software and Wenyuan Building of TongJi University as an example, to analyze the air flow field of indoor natural ventilation and provide the method and theory of air-environment design.

With the development of social economy, building energy consumption takes great proportion in whole society energy consumption. Building energy efficiency technologies especially passive building energy efficiency technologies should be used imminently. This paper researched on the adaptability of passive building energy efficiency technologies in hot summer and cold winter region with Ecotect software. Taking Chongqing, Wuhan, Changsha, Shanghai as the representative areas, this paper analyzed the adaptability of passive energy efficiency technologies which include passive solar heating, thermal storage wall, induced and night ventilation, natural ventilation, direct evaporative cooling,indirect evaporative cooling. Then, some passive building energy efficiency technologies are summarized that suit for the four representative cities through the year.

We investigate the factors (“drivers”) that motivated investment in energy efficiency in commercial real estate office buildings over the 2006–2011 and 2012–2017 period, and looking forward from 2018 in the context of growing concern over carbon emissions around the world. These insights were collected from large Canadian asset managers through interviews conducted in 2017 and 2018. Key findings were that (1) organizations noted an increasing number of factors driving investment decisions over the three periods; (2) cost drivers (payback period and anticipated financial returns) were the top two drivers in 2006–2017; (3) public relations factors became significantly more important looking forward, with brand (reputational impact) as the top-ranked driver and tenant attraction tied for third place; and (4) mitigation against risks such as resilience and anticipated compliance consistently increased in importance. This study contributes to a comprehensive understanding of past, present, and near-future sustainable real estate investment priorities, changing owner behaviors, and the perceived business case for building energy efficiency investments.
