Integrating Virtual Reality and Energy Analysis with BIM to Optimize Window-to-Wall Ratio and Building’s Orientation for Age-in-Place Design at the Conceptual Stage

This study unfolds an innovative approach aiming to address the critical role of building design in global energy consumption, focusing on optimizing the Window-to-Wall Ratio (WWR), since buildings account for approximately 30% of total energy consumed worldwide. The greatest contributors to energy expenditure in buildings are internal artificial lighting and heating and cooling systems. The WWR, determined by the proportion of the building’s glazed area to its wall area, is a significant factor influencing energy efficiency and minimizing energy load. This study introduces the development of a semi-automated computer model designed to offer a real-time, interactive simulation environment, fostering improving communication and engagement between designers and owners. The said model serves to optimize both the WWR and building orientation to align with occupants’ needs and expectations, subsequently reducing annual energy consumption and enhancing the overall building energy performance. The integrated model incorporates Building Information Modeling (BIM), Virtual Reality (VR), and Energy Analysis tools deployed at the conceptual design stage, allowing for the amalgamation of owners’ inputs in the design process and facilitating the creation of more realistic and effective design strategies.

Analysis of BIM application relationship with integration degree of construction environment

As the world pays more attention to low-earbon and sustainable development,there's a growing trend in architecture,engineering and construction fields to construct greener,more energy efficient and more sustainable buildings with the help of building information modeling(BIM).As BIM application becomes popular in industry,more and more scholars and engineers point out that an integrated construction environment is better for BIM's fully functional capability.This paper illustrates the relationship between BIM application and an integrated construction environment based on case survey data.It is found that even though an integration construction environment is not necessary in BIM application,the statistical results showed that DBB(design-bid-build)and CM(construction management)modes have great differences in BIM's application implementation scope and implementation deepness,while DB and CM modes do not.

Integrated landscape approaches to building resilience and multifunctionality in the Kailash Sacred Landscape,China

Climate warming-induced rangeland degradation in arid and semiarid steppe imposes substantial threats to the livelihoods of people.But this dilemma can be solved by combining all sectors of agriculture,animal husbandry and tourism through their complementarity,i.e.by adopting integrated landscape ecosystem-based approaches.A number of experiences and lessons have been achieved in a specific sector for its successful development,but not in the multiple social,economic,and ecological systems.In this study,we use the perspective of integrated ecosystem management to strengthen crop-livestock integration and innovative livelihoods,and propose a multifunctional Kailash Landscape to activate the inter-linkage among agriculture,animal husbandry,and heritage pilgrimage/tourism in order to achieve multiple functions of the socio-ecological system.A case study of Kailash Sacred Landscape Conservation and Development Initiative in China was quantitatively and qualitatively analyzed by land use and land cover change and their consequences on multiple ecosystem services.Integrated landscape management was found to be effective in building resilience of socio-ecosystems by reducing the vulnerability of traditional agriculture in terms of improving crop production and animal husbandry.A multifunctional landscape is expected to be integrated and build a resilient sector complementarity including farming,pastorism,environmental and socioeconomic function.The analyses show that integrated landscape approaches provide an effective perspective for sustainable socio-economic development in this sacred landscape.The findings highlight the importance of landscape-scale ecosystem-based adaptation to environment change.

Integrating Universal Design Standards and Building Information Modeling at the Conceptual Design Stage of Buildings

A projection of the Canadian population shows that in 2024 one in five Canadians will be over 65 years old. This shift forces designers to consider the entire lifetime of occupants during the design of new buildings. Universal Design (UD), which is a design that accommodates all people to the greatest extent possible and aging in place design that is deeply rooted in the principles of UD, aim to house people irrespective of their age, ability, and chronic health conditions. Building Information Modeling (BIM) significantly helps advance the development of the Architecture, Engineering, and Construction (AEC) industry in a more collaborative and automated way. Integrating BIM and UD allows designers to incorporate UD standards easily and efficiently at the conceptual design stage of buildings by using the functionalities and capabilities of BIM tools. Therefore, this study presents the development of an automated computer model to facilitate the adoption of UD standards and processes. The novelty highlighted in this model resides in the creation of an automated method that employs a newly created plug-in and databases to assist designers to incorporate UD standards at the conceptual stage in a timely and cost-effective manner. Furthermore, the study introduces the methodology consisting of collecting, categorizing, and storing data from various universal design and accessible design guidelines in the developed databases and developing new plug-ins in BIM tool to link the developed databases in order to automate the process of retrieving necessary information and components to help designers and owners select optimal design alternatives based on their predefined criteria.

The Contributions of Building Information Modelling to Sustainable Construction

Global concerns toward environmental issues have induced growing demand for new approaches in the construction because of its considerable impact on the environment and use of natural resources. Through using construction sustainability tools, methods and techniques, a greener design can be applied during various building phases. In this connection, it is argued that the analytical and integrated models applied by Building Information Modelling (BIM) may also facilitate this process to be performed more efficiently. BIM and construction sustainability are quite different initiatives, but both have received much attention in recent years in the architecture, engineering and construction (AEC) industry. A rigorous analysis of the interactions between them implies that a synergy exists which, if properly it is understood that can be helpful to reduce the environmental impacts of the AEC industry. A BIM-based design model can contribute to sustainability through its three main dimensions which are environmental, economic and social. In this paper, by reviewing the existing literature on BIM and construction sustainability and using a matrix to analyze construction sustainability dimensions and BIM functionalities a number of interactions have been discussed. It can be concluded that despite there are many improvements in implementation of BIM in environmental and economic aspects of sustainability, its potential impact on social dimension has not been explicitly explored hence further studies need to be undertaken in this area.
