Strategy on applying computational fluid dynamic for building performance evaluation

Predicting and evaluating building performance plays an important role in the training of responsible architects. Building performance includes issues such as: structural stability, acoustic quality, natural lighting, thermal comfort, and ventilation and indoor air quality. These types of analyses are often laborious, non-intuitive, and non-graphical. As a result, these important issues do not arouse the enthusiasm of architecture students or building professionals. The Chinese University of Hong Kong (CUHK) research team proposes to explore and develop a long-term strategy to apply scientific visualization on teaching and research in environmental technology and building performance. This paper presents the development process and results of research projects for applying computational fluid dynamics (CFD) on building performance evaluation. CFD On-line Teaching project's aim is to develop a web-based training course for architecture students to apply CFD simulation on design problem solving. Each lesson not only illustrates basic principles regarding airflow in the building design, it also contains CFD sample files with predefined flow cells for students to test different concepts. GiLin Temple project's aim is to apply CFD simulation on investigating the wind resistance of Tong Dynasty heavy timber structure. Airflow information generated in the project includes the visual representation of the pressure distribution and velocity field on all slices through the temple, and the tracking of particles as they flow around or through a building. The China housing residential airduct study focuses on simulating the indoor airflow regarding the airduct design of China Experimental Urban Housing Scheme. The visual representation of the pressure distribution and velocity field in the airducts provides vital information for helping China Housing Research Center improve the current design.     

围护结构热工性能权衡判断方法及简化形式探讨

围护结构热工性能权衡判断就是判定建筑热工设计节能是否达标,因此以负荷代替能耗作为判据则恰好与判定目的相当。建筑负荷主要与围护结构热工性能相关,而建筑能耗除此之外还与空调采暖系统有关。以负荷判定法代替能耗判定法,能够直接判定围护结构的总体热工性能是否符合节能设计要求,而且《公共建筑节能设计标准》附录B也更适用于负荷判定法。负荷判定法在建模、设定参数上均有大幅度的简化形式。     

Optimizing tradeoffs among housing sustainability objectives

The sustainability of housing units can be improved by integrating green building equipment and systems such as energy-efficient HVAC systems, building envelopes, water heaters, appliances, and water-efficient fixtures. The use of these green building measures often improves the environmental and social performances of housing units; however they can increase their initial cost and life cycle cost. This paper presents a multi-objective optimization model that is capable of optimizing housing design and construction decisions in order to generate optimal/near-optimal tradeoffs among the three sustainability objectives of maximizing the operational environmental performance of housing units, maximizing the social quality of life for their residents, and minimizing their life cycle cost. The model is designed as a multi-objective genetic algorithm to provide the capability of optimizing multiple housing objectives and criteria that include minimizing carbon footprint and water usage during housing operational phase, maximizing thermal comfort, enhancing indoor air and lighting quality, improving neighborhood quality, and minimizing life cycle cost. An application example is analyzed to illustrate the use of the developed model and evaluate its performance. The results of this analysis illustrate the novel capabilities of the model in generating 210 near-optimal tradeoff solutions for the analyzed housing example, where each represents an optimal/near-optimal and unique tradeoff among the aforementioned three sustainability optimization objectives of maximizing the operational environmental performance of housing units, maximizing the social quality of life for their residents, and minimizing their life cycle cost. These novel capabilities of the developed model are expected to improve the design and construction of housing units and maximize their overall sustainability.     

Parametric study on the performance of green residential buildings in China

The parametric study of the indoor environment of green buildings focuses on the quantitative and qualitative improvement of residential building construction in China and the achievement of indoor thermal comfort at a low level of energy use. This study examines the effect of the adaptive thermal comfort of indoor environment control in hot summer and cold winter (HSCW) zones. This work is based on a field study of the regional thermal assessment of two typical cases, the results of which are compared with simulated results of various scenarios of “energy efficiency” strategy and “healthy housing” environmental control. First, the simulated results show that the adaptive thermal comfort of indoor environment control is actually balanced in terms of occupancy, comfort, and energy efficiency. Second, adaptive thermal comfort control can save more energy for heating or cooling than other current healthy housing environmental controls in China's HSCW zone. Moreover, a large proportion of energy use is based on the subjective thermal comfort demand of occupants in any building type. Third, the building shape coefficient cannot dominate energy savings. The ratio of the superficial area of a building to the actual indoor floor area has a significant positive correlation with and affects the efficiency of building thermal performance.     

Environmental assessment of rebuilding and possible performance improvements effect on a national scale

This paper deals with improvement on environmental significant activities related to the life supporting function “building and housing”, using life cycle assessment. In the calculation, back-casting technique is utilised and implies to a future scenario, based on known technology. Besides heating, wastewater treatment is a significant issue, according to the definition of building and housing function practised. The main conclusions from the assessment are that rebuilding is an environmentally better choice than the construction of a new building, if the same essential environmentally related functional performance is achieved. Furthermore, the case study and the national estimates performed prove that the potential environmental impact can be reduced by about 70% for the heating service and 75% for the wastewater system, if the suggested measures are performed.     

Emergy analysis of building manufacturing,maintenance and use: Em-building indices to evaluate housing sustainability

In recent years, integrated building design practices based on the definition of “green building” criteria as common standards of measurement have been promoted. For example, Green Building Rating Systems such as LEED (US) and BREEAM (UK) provide national standards for developing high-performance sustainable buildings. However, integrated environmental accounting methods and global sustainability indicators are still required to evaluate the general environmental performances of buildings, because housing is greatly concerned with global environmental problems such as the use of non-renewable energy, the overexploitation of materials, the exhaustion of resources and the wasting of energy.     

Public Housing Redevelopment: Opportunity for Community Regeneration?

This article reviewing Australian and international research on community regeneration within public housing redevelopment, explores implications for Victoria, in building community sustainability within the context of a public-private mix. It shows that the requirements for successful redevelopment are similar to those for sustainable communities, with a need to attend simultaneously to economic, social and environmental development. Public housing redevelopment presents particular challenges requiring careful attention to design, services, management and safety. Equally important are the tasks of confronting social exclusion and poverty. Building community empowerment, cohesiveness and problem-solving capacity require both initial effort and ongoing investment because of the impacts of disadvantage and resident mobility.
