Assessment of green roof performance for sustainable buildings under winter weather conditions

A green roof is a specialized roof system that supports vegetation growth on rooftops.This technology is rapidly gaining popularity as a sustainable design option for buildings.In order to contribute to an understanding of green roof in regions with cold winters and snow,an on-site experimental investigation was present with a focus on the assessment of green roof performance during the winter.This field experiment took place on a six small buildings during the winter of 2010-2011.The work monitored three buildings with green roofs,two buildings with reference roofs and one building with a bare soil coverage for the roof.These six buildings were identically constructed and instrumented with sensor networks to provide heat flux data through the roofs.The 15 min averaged data were statistically analyzed for a week under the two separate periods,first without a snow cover and second with a snow cover.The results show that the roof type is a significant factor in affecting the thermal performance of these buildings.Most importantly,green roofs reduce heat flow through the roof and thus reduce the heating energy demand during the winter.However,the energy savings for buildings with the green roofs are reduced under snow conditions because the snow diminishes thermal resistance of the roof and increases the heat transfer process through the roofs.

Research on Evaluation System of Green Residential Buildings in Cold Areas of Sichuan

With regard to the rapid growth of China’s building area and the increasing energy consumption of buildings, green buildings have become an important issue for balancing economic development and environmental impact. However, the current evaluation systems for various types of green buildings are often unable to achieve a set of standards in practice due to the distinct regional characteristics of each region. Therefore, in view of the regional characteristics of the climate, terrain, ecology, and economic development in the cold regions of Sichuan, it is important to study the evaluation system of green residential buildings suitable for the cold regions of Sichuan. This article focuses on the regional characteristics of climate, topography, ecology, and economic development in the cold regions of Sichuan, and discusses the limitations of the current standards on the practice of green building in cold regions of Sichuan through a sociological questionnaire survey on the comfort of living in the local population. Then from the two dimensions of the advantages of traditional houses and the particularity of national culture, the strategies for the optimization and improvement of the evaluation index system for green residential buildings in the cold regions of Sichuan were proposed. After comprehensively considering the factors that affect the green residential buildings, including the regional characteristics of the cold regions of Sichuan, and the green performance of buildings, local characteristics and ethnic features were included in the evaluation system. The evaluation index system of green residential buildings in the cold regions of Sichuan, consists of 92 three-level indicators. A professional hierarchical analysis software yaahp was used to establish a multi-level hierarchical model between the indicators, and the indicators were compared with each other layer by layer to clarify the importance of the indicators. Based on this, a judgment matrix for each layer was constructed and obtained. The weight of each indicator is accurate, and the scoring mechanism and grading standards are constructed according to it. Through the calculation, the consistency test of the entire model was passed, thereby confirming the scientificity and rationality of the entire evaluation system.

Shifting Ground - Changing Attitudes to the Green Revitalization of New Zealand＇s Existing Office Buildings

This paper explores the shift in the attitudes of building developer/owners to the incorporation of sustainability measures into office building renovations in New Zealand over the last 7 years, through a series of interviews with a wide range of key industry players and the study of three seminal case study examples. The interviewees uniformly considered that there had been a rapid increase in interest in the green renovation of existing buildings during the period under consideration, due mainly to strong leadership by central government. Significant differences in attitudes to green renovation emerged between the various groups as to whether, and on what terms such developments were likely to occur. The move to green building solutions seems to have continued in New Zealand, despite the world financial crisis and central government＇s abrogation of its leadership role being replaced by rising tenant expectations and the need for building owners to let their premises in a more competitive leasing environment. The change in attitudes demonstrated is profound. In the earliest of the case study buildings, started on site in 2004, no consideration is given by the developer, owner or design team to sustainability issues and there is no obvious user demand. In the second case, which started on site only one year later, sustainable design is very prominent, but is largely tenant driven, albeit with the active and enthusiastic support of the developer and design team. The final case study building started on site in 2007 is entirely developer/building owner driven and stems from a perception that ＂green＂ buildings represent value for money, that there is a real and persistent user demand and that sustainable design makes strong commercial sense.
