The Impact

Improving the energy performance of existing buildings is one of the main strategies defined by the European Union to reduce global energy costs. Amongst the actions to be carried out in buildings to achieve this objective is working with passive measures adapted to each type of climate. To assist designers in the process of finding appropriate solutions for each building and location, different tools have been developed and since the implementation of building information modeling (BIM), it has been possible to perform an analysis of a building’s life cycle from an energy perspective and other types of analysis such as a comfort analysis. In the case of Spain, the first BIM environment tool has been implemented that deals with the global analysis of a building’s behavior and serves as an alternative to previous methods characterized by their lack of both flexibility and information offered to designers. This paper evaluates and compares the official Spanish energy performance evaluation tool (Cypetherm) released in 2018 using a case study involving the installation of sunlight control devices as part of a building refurbishment. It is intended to determine how databases and simplifications affect the designer’s decision-making. Additionally, the yielded energy results are complemented by a comfort analysis to explore the impact of these improvements from a users’ wellbeing viewpoint. At the end of the process the yielded results still confirm that the simulation remains far from reality and that simulation tools can indeed influence the decision-making process.

Performance Results

This study demonstrates the research and development of a visualization method called thermal performance simulation. The objective of this study is providing the results of thermal performance simulation results into building information modeling (BIM) models, displaying a series of thermal performance results, and enabling stakeholders to use the BIM tool as a common user interface in the early design stage. This method utilizes a combination of object-oriented physical modeling (OOPM) and BIM. To implement the suggested method, a specific BIM authoring tool called the application programming interface (API) was adopted, as well as an external database to maintain the thermal energy performance results from the OOPM tool. Based on this method, this study created a prototype called the thermal energy performance visualization (TEPV). The TEPV translates the information from the external database to the thermal energy performance indicator (TEPI) parameter in the BIM tool. In the TEPI, whenever BIM models are generated for building design, the thermal energy performance results are visualized by color-coding the building components in the BIM models. Visualization of thermal energy performance results enables non-engineers such as architects to explicitly inspect the simulation results. Moreover, the TEPV facilitates architects using BIM as an interface in building design to visualize building thermal energy performance, enhancing their design production at the early design stages.

Wall Materials

During the previous two decades, the energy saving potential using systematic building management is considered to be important which should be considered through the building lifecycle. Among the wide range types of different buildings, Public buildings are considered as one of the biggest energy-consuming sector in the world and major part of this amount is used by the air conditioning system especially in tropical climates. The most effective decisions related to sustainable design of a building facility are made in the feasibility and early design stages. Building Information Modeling (BIM) can expedite this process and provide the opportunity of testing and assessing different design alternatives and materials selection that may impact on energy performance of buildings. This paper aims at evaluating the efficiency of various types of wall materials with regard to theirs properties on energy saving. The case study in this paper is modeled by means of BIM application and then simulated by software, which is appropriate for energy analysis. The current energy consumption patterns of this case identified and shifted to the optimized level of energy usages by changing the walls materials to find most optimized of walls materials. Modification most optimized wall materials and energy analysis indicated 9347 Wh in Per meter square of electrical energy saving.

Building Information

Building information modeling (BIM) has been advocated as a potential solution to many challenges of asset management, such as missing data, incompatible software, and unclear business process. However, its current implementation in infrastructure projects has only accounted for technology application and digital information delivery without considering system compatibility or information need. More significantly, BIM implementation requires compatible development of various aspects of a business, a gap in which can lead to different implementation levels or even project failure. Limited research is available on the key factors and challenges of BIM implementation in infrastructure projects. Therefore, this study aims to present a case study with particular emphasis on interviews with key stakeholders to explore the main challenges and solutions of BIM implementation. It starts with the development of interview questionnaires based on literature review and feedback from a research team composed of key stakeholders. Interviews were conducted with 37 professionals from stakeholders of the owner, designers, contractors, and software vendors. Four main factors and challenges, along with potential solutions, were identified from content analysis of the interviews: (i) isolation of project phases (process factor), (ii) incompatibility of project technologies and interfaces (technology factor), (iii) unclear definition of requirements and responsibilities of project stakeholders (people factor), and (iv) imperfect information collection and sharing (information factor). The four factors dictate “when,”“how,” and “what” information should be collected and communicated by “whom,” which are mutually interdependent, and focusing on limited factors instead of all four can compromise the successful implementation of BIM.

Simulation Results

PurposeThe operational phase of a building's lifecycle is receiving increasing attention, as it consumes an enormous amount of energy and results in tremendous detrimental impacts on the environment. While energy simulation can be applied as a tool to evaluate the energy performance of a building in operation, the emergence of Building Information Modeling (BIM) technology is expected to facilitate the evaluation process with predefined and enriched building information. However, such an approach has been confronted by the challenge of interoperability issues among the related application software, including the BIM tools and energy simulation tools, and the results of simulation have been seldom verified due to the unavailability of corresponding experimental data. This study aims to explore the interoperability between the commonly used energy simulation and BIM tools and verifies the simulation approach by undertaking a case study.Design/methodology/approachWith Autodesk Revit and EnergyPlus selected as the commonly used BIM and energy simulation tools, respectively, a valid technical framework of transferring building information between two tools is proposed, and the interoperability issues that occur during the data transfer are studied. The proposed framework is then employed to simulate the energy consumption of a single-family house, and sensitivity analysis and analysis on such parameters as schedule are conducted for building operations to showcase its applicability.FindingsThe simulation results are compared with monitored data and the results from another simulation tool, HOT2000; the comparison reveals that EnergyPlus and HOT2000 predict the total energy consumption with a difference from the monitoring data of 8.0 and 7.1%, respectively.Practical implicationsThis research shows how to efficiently use BIM to support building energy simulation. Relevant stakeholders can learn from this research to avoid data loss during BIM model transformation.Originality/valueThis research explores the application of BIM for building energy simulation, compares the simulation results among different tools and validates simulation results using monitored data.

The Impact

Building Information Modeling (BIM) for optimizing the total lifecycle cost of buildings is a challenge even today. Inadequate software interoperability, high costs as a result of the fragmented nature of the building industry, lack of standardization, inconsistent technology adoption among stakeholders are just some of the obstacles that architects and engineers face. However, optimization requires a structured procedure that enables continuous changes in design variables and assessment on energy consumption. A holistic building design and construction are already introduced in Europe through the energy performance of buildings directive (EPBD). The requirements have been strengthened by the EPBD recast for achieving cost optimal building designs for the life cycle of the building, moving towards nearly zero energy buildings by the end of the decade. BIM and intelligent services could play a crucial role in these efforts with improved visualization and productivity due to easy retrieval of information, increased coordination of data and exchange of information, all leading to a reduced cost for the design of energy efficient buildings. An ongoing European research project aims to contribute to these needs by developing a Virtual Energy Laboratory that will support building energy performance simulations taking into account the stochastic nature of input parameters and processes. This will be supported by information communication technology features utilizing the necessary computational power through cloud computing. This paper presents an overview of the ongoing efforts and focuses on results for assessing the impact of different input weather and climate data that are pertinent in building load and energy performance calculations.

The Singaporean government has made building information modeling (BIM) implementation mandatory in new building projects with gross floor areas over 5000 m2, but the implementation is still plagued with hindrances such as lacking project-wide collaboration. The purposes of this study are to identify critical factors hindering BIM implementation in Singapore’s construction industry, analyze their interrelationships, and identify strategies for reducing these hindrances. The results from a survey of 87 experts and five post-survey interviews in the Singaporean construction industry identified 21 critical hindrances, among which “need for all key stakeholders to be on board to exchange information” was ranked top. These hindrances were categorized into lack of collaboration and model integration (LCMI), lack of continuous involvement and capabilities (LCIC), and lack of executive vision and training (LEVT). LEVT and LCIC contributed to LCMI; LEVT caused LCIC. The proposed framework implying the key hindrances and their corresponding managerial strategies can help practitioners identify specific adjustments to their BIM implementation activities, which enables to efficiently achieve enhanced BIM implementation. The hindrances identified in this study facilitate overseas BIM implementers to customize their own lists of hindrances.

In the contemporary milieu of today, sustainability and environmental concerns have become a great subject of debate. Matters related to sustainability are often linked to other crucial concerns like energy consumption. Energy is a key factor in ensuring continuous economic growth and development. One of the highest energy consuming systems in buildings – specifically residential homes in tropical regions – is the air conditioning system. Windows have been identified as the weakest link in the fabric of a building as they serve as thermal holes. Thus, the selection of proper window materials is crucial to reduce energy usage by minimizing the cooling and heating requirements of the building. The aims of this paper are analysis of energy performance for diverse types of window’s glazing with different frames in order to find the most optimized window materials for the tropical residential buildings. The selected case study in this paper is modeled and then simulated by Building Information Modeling (BIM) application, which is appropriate for energy analysis. For simulation, some factors of the window materials were taken into consideration including, four physical properties of the U-factor, solar heat gain coefficient, visible transmittance, and emissivity. The result was shown windows types 02 and 03 were the most optimized of window materials and led to 10% energy saving into the base model and the windows type 05 was high U-factor, results in a greater transfer in internal zones and led to high energy consumption.
