Purpose Buildings and their use is a complex process from design to occupation. Buildings produce huge volumes of data such as building information modelling (BIM), sensor (e.g. from building management systems), occupant and building maintenance data. These data can be spread across multiple disconnected systems in numerous formats, making their combined analysis difficult. The purpose of this paper is to bring these sources of data together, to provide a more complete account of a building and, consequently, a more comprehensive basis for understanding and managing its performance. Design/methodology/approach Building data from a sample of newly constructed housing units were analysed, several properties were identified for the study and sensors deployed. A sensor agnostic platform for visualising real-time building performance data was developed. Findings Data sources from both sensor data and qualitative questionnaire were analysed and a matrix of elements affecting building performance in areas such as energy use, comfort use, integration with technology was presented. In addition, a prototype sensor visualisation platform was designed to connect in-use performance data to BIM. Originality/value This work presents initial findings from a post occupancy evaluation utilising sensor data. The work attempts to address the issues of BIM in-use scenarios for housing sector. A prototype was developed which can be fully developed and replicated to wider housing projects. The findings can better address how indoor thermal comfort parameters can be used to improve housing stock and even address elements such as machine learning for better buildings.
Purpose – The purpose of this study is to examine the feasibility of using 3D simulation transfer processes to streamline the environmental assessment of buildings that have been designed digitally using building information modelling (BIM). The case study presented relates to a competition (“Build Qatar Live”) in which one of the winning team’s objectives was to create a smart process for assessing the design against the Leadership in Energy and Environmental Design (LEED) criteria. The experience indicated that a rapid, concurrent and efficient LEED evaluation was possible within the BIM process. The study presents technological approaches that can be adopted within the BIM environment to simplify the environmental assessments and embrace practices that reduce environmental and ecological impacts. Design/methodology/approach – The methodology encompassed an overview of how rapid high-value data exchange occurs within BIM to achieve a sustainable building design as part of an international design competition. Achieving a LEED rating through sustainable design was a key requirement of the competition. Findings – The findings of this case study has revealed that key credits in LEED can be integrated within the BIM design process. Therefore, tackling such important environmental design issues in parallel to building design and providing key information on building elements needed to meet the sustainability criteria. Originality/value – This research highlights the benefits of streamlined, architectural and data software exchange through applying data interoperability of a building design; thus, skipping conventional 2D building and conventional documentation for environmental and energy designs simulations needed for LEED certifications and general low carbon design.
Purpose-This paper provides a conceptual framework for an integrated asset management strategy making use of available facility environmental assessment methods and tools and proposes areas of commonality between these and the matured as-built Building Information Model (BIM), that becomes the Asset Information Model (AIM). This framework considers emerging requirements for the capture of Building Performance Attribute Data (BPAD), and describes how these can be managed in order to assist with effective post-construction building performance evaluation. Design/methodology/approach-A review of the current process relevant to the development of as-built BIMs and AIMs was undertaken which included a discussion of BIM standards and of the COBie process. This review combined with data provided by industry practitioners, led to the identification of the requirement of BPADs which can be used within existing green building tools, such as BREEAM In-Use, LEED and integrated with COBIE and FM /Asset management methods. In turn these methodologies were used to identify possible synergies and areas of integration in AIM-enabled environments. Findings-Recognising the cyclical nature of asset management and BIM, a conceptual model was generated. It was found that BPADs could be aggregated within an AIM model which could influence the delivery of effective facilities and asset management. The model considers the use of existing Building Management Systems (BMS) and Computer Aided Facility Management Systems (CAFMs) and identifies issues associated with the overall sustainability strategy. Originality value-A conceptual framework is generated that proposes the use of effective information management and aggregation of building performance attribute data within an Asset Information Model.

AbstractPurpose -The construction industry has focused on operational and embodied energy of buildings as a way of becoming more sustainable, however, with more emphasis on the former. The purpose of this paper is to highlight the impact that embodied energy of construction materials can have on the decision making when designing buildings, and ultimately on the environment. This is an important aspect that has often been overlooked when calculating a building's carbon footprint; and its inclusion this approach presents a more holistic life cycle assessment. Design/methodology/approach -A building project was chosen that is currently being designed; the design team for the project have been tasked by the client to make the facility exemplary in terms of its sustainability. This building has a limited construction palette; therefore the embodied energy component can be accurately calculated. The authors of this paper are also part of the design team for the building so they have full access to Building Information Modelling (BIM) models and production information. An inventory of materials was obtained for the building and embodied energy coefficients applied to assess the key building components. The total operational energy was identified using benchmarking to produce a carbon footprint for the facility. Findings -The results indicate that while operational energy is more significant over the long term, the embodied energy of key materials should not be ignored, and is likely to be a bigger proportion of the total carbon in a low carbon building. The components with high embodied energy have also been identified. The design team have responded to this by altering the design to significantly reduce the embodied energy within these key components -and thus make the building far more sustainable in this regard. Research limitations/implications -It may be is a challenge to create components inventories for whole buildings or for refurbishments. However, a potential future approach for is application may be to use a BIM model to simplify this process by imbedding embodied energy inventories within the software, as part of the BIM menus. Originality/value -This case study identifies the im...
