"Thermal Performance of Building Envelopes for Improved Energy Efficiency "

Buildings are energy intensive, and the starting point to achieve energy efficiency is to address the thermal performance of their envelopes. In tropical climates, air-conditioned buildings in cities can account for more than 30% of the total electrical energy consumption. A typical air-conditioned building operates with a moderate temperature difference varying from about 6 to 12oC between outdoor and indoor, and air conditioning can account for more than 50% of the energy consumption of the building. In this presentation, we report on the recent effort to develop an enhanced method to credit the energy performance of buildings by accounting more precisely for the heat gain streams through the building envelope. Our study is motivated by new technology and improved fenestration insulation such as the thermally broken window frame. We developed new correlations to account for the thermal performance of improved window components and systems. The methodology enables investigations of the impact on building cooling energy arising heat flows through window components and frames. The enhanced method is incorporated into the existing Envelope Thermal Transfer Value (ETTV) and the Residential Envelope Transmittance Value (RETV) formulations, which are necessary criteria in the Singapore Green Mark mandatory certification scheme. With the enhanced ETTV and RETV criteria, the refreshed envelope energy standard offers opportunities and better incentives for the adoption of “green” and energy efficient technology towards achieving sustainable building energy performance.

"Several key issues about the Green Building "

Based on the analysis of green buildings with more than 30 years development, discuss several key issues about the Green Building: 1, By reconsidering the substance,redefine the concept and scope of the Green Building.Summarize the main items and coping strategies. 2,In view of the problems in the new period, conclude the core plates of the Green Building. 3, Analyze the misunderstanding and problems of the value oriented practice of the Green Building. 4, Analyze the relationship between the development of green buildings and the overall development direction of architecture. It is hoped that by thinking about the above key issues, we can find new ideas for solving the problems of green building in present-days.

Ms. Jiao received her master’s degree of Architect from Architectural Department of Tianjin University. She is a professorate senior engineer, a national first-class registered architect. She mainly focuses on the directions of sustainable city and buildings, including eco-city, green building, accessibility design etc. She has carried out and completed a number of design and research projects, published a number of articles and papers, won multiple design and research awards at national and provincial level.
