In this paper, a novel use of building materials and their impact on the building performance and its climatic adaptability is explored, based on a complex case study of a unique low energy sustainable building project. In particular, an innovative use of sycamore and its suitability as a structural and constructional timber has been investigated and reported, given that the current codes of practice deem that is not appropriate for structural applications due to its durability. A research method of in-situ longitudinal study has been adopted, concentrating on the monitoring and assessment of its structural performance and conditions in which it might deteriorate. On the component level, the research reports on the methods and standards of sycamore grading and classification, service classes, resistance to decay, impact of the moisture movement and results of its laboratory and in situ testing. On the system level, the climatic adaptability of the building as a whole has been analysed via dynamic performance simulation and compared to the in situ measurements. This was important in order to develop a holistic building performance monitoring strategy, but in particular, to understand the impact of building microclimate on the sycamore frame and hempcrete components of the external load-bearing wall. So far research has concluded that sycamore can be used as structural and constructional material in building design, but due attention has to be paid to construction detailing and provision of a breathable, low humidity environment with an effective resistance to decay and insect attack. This includes measures that ensure a low equilibrium moisture content conditions, effective ventilation provision and appropriate service class uses. It is important to state however, given the single site locality of sycamore sourcing, that results can only be interpreted in the context of the given case study, i.e. they cannot be extrapolated to broader geographical extents.

The increasing complexity of urban growth strongly impacts both on the quality of urban environment and on the effectiveness of models for development, requiring innovative approaches to face the related challenges. The proposed position paper reports the methodological approach outlined within a trans-European research project. It aims at defining a systemic urban vision based on resource loops vision in a clustered perspective, overcoming the conventional separation between urban and periurban areas. The main scope is to drive a transition from a linear (“take-make-use-dispose”) to a circular approach, considering the whole city realm and aiming to close resource loops (in line with EU COM 614/2015, Closing the loop, EU COM 33/2017, Implementation of the Circular Economy Action Plan and Urban Agenda Draft Action Plan on Circular Economy 09.02.2018) while generating new market opportunities and jobs, reducing resources import, decreasing impacts on environment and climate change. The methodology includes the following steps: increasing context understanding, identifying resource flows, using economic potential of existing resources, engaging communities in loops of proximity, facilitating entrepreneur and stakeholders in co-creation of circular economy processes. This paper explains the positioning of the research within the state of the art; it describes the applied methodology and related expected outcomes, defines the main related initiatives and implementation models. This study identifies regenerative corridors (RC) as potential effective drivers to overcome the conventional separation between urban, peri-urban and rural areas in the EU context, investigating their relations and identifying driving factors for a circular equalized development among these different urban zones. This paper also reports on the impact indicators and the replication potential of the proposed systemic approach.

This examines The Eddy, a new construction mixed-use, multifamily residential project in Boston, MA USA as a model for sustainable and resilient urban waterfront redevelopment that celebrates place – rather than evoking fear – while building a sense of community and continuity along the waterfront. The Eddy is situated in the neighbourhood of East Boston on low-lying, reclaimed former-industrial land. Because of its place along the waterfront, this building is one of many projects viewed as a linchpin for a unified front against rising sea level, storm surge, and climate change for the entire neighbourhood. This study explores drivers for resiliency on this project, as well as strategies and tools used by the designers, construction team, and municipality leadership in incentivising and directing sustainability and resiliency efforts in a coordinated fashion on this and adjacent properties. Then, the paper explores the project’s siting, landscape, architecture, interior design, and mechanical considerations and how each impact greater sustainability and resiliency outcomes. Finally, the paper will share the results of these implemented strategies, including operational cost savings, project marketability, and reduced insurance premiums as a result of the resilient and sustainable design approach, proving synergy and return on investment for implementation of each in tandem. The goal is to illustrate that through cooperation between public and private partnerships, cities can grow and densify intelligently while promoting increased resiliency, sustainability, density, identity, and waterfront access – applicable to any waterfront city.

The housing sector is responsible for more than 50% of global resource extraction, about 50% of world energy consumption, 1/3 of water consumption and furthermore generates about 1/3 of all produced waste. A new, circular approach is needed to enable better decision-making on the selection of innovative architectural solutions for all phases of a building’s life cycle. The current building sector’s business model must be redesigned to include the application of new and improved methods, solutions and innovative services, and advance a positive transition from a linear economy to a circular economy. We will present the circular interventions carried out on a centenary building located in Vienna in the framework of the HOUSEFUL project. HOUSEFUL is an EU-funded initiative with the objective to develop and demonstrate integrated circular services, focusing on the optimal management of resources throughout the life cycle of new or existing buildings. The demonstration will include technologies to circulate all process flows while reducing the overall energy demand. These technologies will be offered as integrated services to produce treated rain and wastewater for internal reuse, the generation of renewable energy from biogas, compost production combined with urban gardening and for the use of nutrients in a greenhouse. The design of more efficient processes, such as green walls, innovative conservatories, building-integrated solar thermal and photovoltaic panels will improve building energy efficiency. All process flows will be intensely monitored to ensure safety and collect data for further replication cases. The solutions will also include the use of sustainable and upcycled materials and the implementation will be based on the principles of reversibility and de-constructability. The final services of the building will be elaborated in co-creation workshops with a multitude of stakeholders. Additional service-oriented modelling facilitates replication for the transition to the circular housing sector.

Research has proved that urban green space can be utilized to promote public health. While exploring the underlying mechanism, the main focus is always on the meso-scale characteristics of urban green space such as accessibility, availability, proximity, and its micro-scale attributes like area, quantity, constituent elements and environmental perception. Yet, its spatial distribution, as the macro-scale characteristics of urban green space, is also closely related to residents’ health but has not well been explored. Regarding this, this paper takes the inner-city area of Wuhan as an example to evaluate the spatial distribution of the green space with Jiedao as the basic analysis unit. By buffer analysis and zonal analysis, the evaluation is conducted from five dimensions which are balance, equality, availability, accessibility and quality. The results show that, except in balance, the distribution of health-promotion green space is not satisfactory in the other four dimensions, especially in accessibility, quality and equality. The underlying causes could be attributed to three aspects of the current urban green space planning: (1) emphasis on ecology-oriented value and the application of “top-down” planning approach; (2) adoption of a single-dimension index system; (3) application of a static but not an adaptive framework. Therefore, from planning perspective, to shift the value-orientation and readjust the framework of urban green space planning will be one key solution to the identified problems.

This paper discusses information from a research project investigating a new approach to designing energy positive buildings that integrate renewable energy generation into the building fabric. Such buildings can help reduce energy consumption and associated carbon emissions, alleviating fuel poverty and lessening the need for costly grid upgrades. The main purpose of this study is to highlight the current status of the UK construction industry and the need for improvements, which have been documented over the years. Several enablers for the construction industry to change are identified, including collaborative procurement methods, building information modelling (BIM), innovation and energy positive buildings. The key findings from the review provide evidence that the energy positive solutions put forward in this research project, linking collaboration, innovation and buildings with reduced energy use and carbon emissions, could be used to improve the overall performance of the construction industry. This provides a good knowledge base for the next phase of the research, which includes interviews and workshops with construction industry stakeholders to further identify the challenges, benefits and drawbacks of the potential building integrated energy positive solutions. The combined body of information gleaned from this literature review, the feedback from construction industry stakeholders, and case studies of energy positive buildings designed by the first author, will be used to aid the development of the proposed outcomes of the research project, which will include a continuous improvement tool, the case studies themselves and the development of an innovation portal.

A courtyard is an architectural design element traditionally and commonly integrated in UAE vernacular architecture for its environmental and social potential that reflects the sustainable design bases in traditional architecture. This research provides a qualitative study on the usefulness of courtyards as passive energy saving systems in the UAE. This includes my investigation into traditional old houses in Sharjah, to compare their courtyards’ traditional use with the recent use of these courtyards after renovations and the changes in functions of some houses that currently are used as art exhibitions or museums. The research purpose is to focus on the application of courtyards in the context of the Heart of Sharjah public buildings, that reused the internal courtyards spaces for various community activities to create a socially active hub, to represent the cultural and traditional aspects for the Emirates community and its recognizable character, that express the community’s cultural needs and extend the communication roots by introducing some historical background to new generations. The aim is also to raise awareness of the potential environmental aspects of courtyards in the hot dry climate of the UAE, with respect to the vision of sustainable architecture that reflects the natural context, including the climate conditions, the human context, and traditional cultural values. In addition, the research investigates the strength of the relation between the well-designed courtyard and its occupants’ social behavior: the social aspects of sustainability traditionally and recently as well. The research study is qualitative and based on interviews, surveys and technical measurements that targeted public visitors to the selected buildings as a case study. The results from the analytical part of the research, including a list of recommendations to be applied to the traditional houses in Sharjah for their renovation and preparation for public use in terms of the cultural building principles that match the traditional and environmental aspects of sustainability.

The façade cladding of a building is a system responsible for providing and maintaining the comfort of the indoor environment as both thermal and acoustic insulation, as well as protecting the building envelope from weathering agents. Moreover, these systems have visual, aesthetic and cultural purposes. One of the most used façade coatings is ceramic tile, which is able to provide appropriate resistance to weather, but with an elevated rate of degradation. Such downside results are the loss of performance, quality and that the building may not reach its estimated service life. For this reason, the adaptation of architectural design to the natural environment is important. The present paper aims at measuring the action of weather agents on a sample of three buildings under construction in Brasília, Brazil. We used hygrothermal simulation software, WUFI Pro 6.0, to quantify the results for wind-driven rain, radiation and temperature on the north, south, east and west orientation of these buildings. The results of global radiation and wind-driven rain presented the same order of incidence, and the most critical values occurred during the dry period, for the north and west orientations. The variations of surface temperature in general reached maximum values on the north and west façades. A temperature gradient was also quantified, revealing a similar trend to the previous results. Furthermore, results were useful in identifying maintenance strategies and for service life prediction for the three buildings’ casings, and show advances in the design phase, by learning from nature and traditional construction techniques.
建筑的正面覆层是一个系统，负责提供和保持室内环境的舒适性，作为隔热和隔音，以及保护建筑围护结构免受风化剂的影响。此外，这些系统具有视觉、美学和文化目的。最常用的表面涂层之一是瓷砖，它能够提供适当的耐候性，但降解率较高。这样的负面结果是性能和质量的损失，建筑物可能无法达到其预计的使用寿命。因此，建筑设计对自然环境的适应性就显得尤为重要。本文旨在测量气象因子对巴西Brasília三个在建建筑样本的作用。我们使用WUFI Pro 6.0温湿度模拟软件，对这些建筑的北、南、东、西4个朝向的风雨、辐射和温度进行量化。全球辐射和风驱动降雨的结果呈现相同的发生顺序，在干旱期，北和西两个方向出现了最大的临界值。地表温度变化总体上在北部和西部高原达到最大值。温度梯度也被量化，揭示了与之前结果相似的趋势。此外，通过学习自然和传统建筑技术，研究结果在确定维护策略和预测三栋建筑外壳的使用寿命方面很有用，并显示了设计阶段的进步。

Feng Shui, literarily translated as wind and water, forms part of the Chinese traditional architecture theory. The philosophy aims to achieve harmonious equilibrium among nature, buildings and people. It continues to be used in dwelling site selections and layout of buildings as well as in the environmental planning, especially in the Form School Feng Shui school of thought. It focuses on site analysis, landscapes and building placements with emphasis on designing with nature and the environment. This Feng Shui approach can be traced in the building design of the Peranakan style architecture of Cheong Fatt Tze Mansion, a unique architecture in George Town, Penang. It is a mix of Chinese, Malay and colonial building styles. Unfortunately, this mansion has not been verified with the Feng Shui approach in relating the architecture with nature, despite a claim that was made of its application and for other buildings of the same style. This study addresses the cultural sensitivity of this architecture as a case study in embracing nature for its Feng Shui application. Qualitative analysis was employed to determine whether the design of this mansion corresponded well with favourable architectural conditions placed in the environment as stated in the Form School approach. The method applied included measured drawings, ethnography study of the Peranakan culture, interviews with identified Feng Shui masters and the mansion’s owners. The mansion’s architectural design conformed to the philosophy adapted from the Form School approach, especially in the architectural language. The conformity further addresses challenges and opportunities in pursuing the sustainable design approach based on the significance of Feng Shui, pertaining to the minimum use of energy and exploitation of natural ventilation and natural lighting. The Feng Shui Form School approach has significantly demonstrated the interrelationships between the architecture and the environment, specifically in this Peranakan architecture of Penang.
{"title":"THE ENVIRONMENT AND FENG SHUI APPLICATION IN CHEONG FATT TZE MANSION, PENANG, MALAYSIA","authors":"A. Bahauddin, Teh Boon Soon","doi":"10.2495/arc180011","DOIUrl":"https://doi.org/10.2495/arc180011","url":null,"abstract":"Feng Shui, literarily translated as wind and water, forms part of the Chinese traditional architecture theory. The philosophy aims to achieve harmonious equilibrium among nature, buildings and people. It continues to be used in dwelling site selections and layout of buildings as well as in the environmental planning, especially in the Form School Feng Shui school of thought. It focuses on site analysis, landscapes and building placements with emphasis on designing with nature and the environment. This Feng Shui approach can be traced in the building design of the Peranakan style architecture of Cheong Fatt Tze Mansion, a unique architecture in George Town, Penang. It is a mix of Chinese, Malay and colonial building styles. Unfortunately, this mansion has not been verified with the Feng Shui approach in relating the architecture with nature, despite a claim that was made of its application and for other buildings of the same style.
