With the increasing number of nearly zero-energy buildings (NZEB) due to increase of global awareness on climate change, the new concepts of design and control must be developed because of great NZEB dependency on detailing and multidisciplinary approach. This paper proposes a three-level gateway control method for NZEB project delivery by using digital representation of the building in building information modeling (BIM) environment. These controls (C1, C2 and C3) are introduced before three main phases of any project delivery—design phase, construction phase and handover. The proposed project control procedure uses black-box building energy modeling within the BIM environment, so the paper explores the reliability of one tool for direct energy modeling within the BIM-authoring software. The paper shows two types of validation tests with satisfactory results. This leads to conclusion that analyzed tool for energy simulation within BIM environment can be used in a way that is described in a proposed project control procedure. For further research it is proposed to explore reliability of tools for energy simulation connected to other BIM-authoring software, so this project control procedure could be independent of BIM-authoring software used in the paper.

Schedule Performance

In the recent years, owners and construction management companies have shown an increasingly more interest in adopting approaches that result in enhanced quality and less risks, conflicts, and wastes on their projects despite potentially higher initial cost. Implementing advanced technology trends and incorporating more integrated methods of delivering projects have proven to be highly value-adding and forward-thinking approaches. The objective of this research was to evaluate the effectiveness of and the synergy between three of such trending concepts in the construction industry, namely, integrated project delivery (IPD), lean principles, and building information modeling (BIM) in terms of cost and schedule performance measures. Data analysis was conducted on 72 vertical projects through interviews and study of the published articles, reports, and case studies. Qualitative analysis was performed through grounded theory while quantitative analysis was implemented using univariate and multivariate analysis of variance tests on schedule performance and cost performance. Results of the grounded theory analysis summarize six crucial characteristics required for an effective coordination between IPD, lean construction, and BIM. Statistical analysis on different combination of these three components revealed considerable effectiveness in terms of schedule performance while the effect on cost performance was not as much significant. This study contributes to the body of knowledge and practice in the field of construction by demonstrating the cost and schedule benefits realized through the use of IPD, lean construction, and BIM and identifying their collective conceptual advantages.

Integrated Project

A integração de projetos é uma necessidade cada vez mais real no desenvolvimento de projetos de construção. O avanço da tecnologia, especialmente em relação ao BIM (Building Information Modeling), proporcionou maior facilidade para o compartilhamento de informações e integração de projetos. No entanto, ainda há poucos casos de uso dessa abordagem no Brasil, que em sua versão mais madura é denominada IPD (Integrated Project Delivery). Assim, foi realizado um estudo de dois casos que aplicaram princípios de projeto integrado, com diferentes níveis de maturidade, da mesma empresa, localizada em Fortaleza/CE, e buscou-se identificar os pontos que levaram à melhoria do processo. Como resultado, houve um grande ganho de eficiência de um caso para outro, principalmente devido a três fatores: (a) melhor metodologia para realização de reuniões; (b) utilização de contrato integrado; e (c) melhor integração e sincronização de informações através do software utilizado e da evolução dos serviços de rede compartilhados, que permitiram maior interação entre projetistas. Entretanto, foi possível identificar que os casos ainda não atingiram a total integração, principalmente devido a diversas barreiras, como a adoção de Open Book, compartilhamento de riscos e recompensas e participação de todas as equipes desde as fases iniciais dos projetos.

Building Information

There is increasing need to apply building information modeling (BIM) to low energy buildings, this includes building energy modeling (BEM). If a building energy model can be flawlessly generated from a BIM model, the energy simulation process can be better integrated within the design, can be more competent, and timesaving. However, concerns about both the reliability and integrity of the data transfer process and the interoperability between the BIM and BEM prevent any implementation of BIM-based energy modeling on a large scale. This study addresses the accuracy and integrity of BIM-based energy modeling by investigating how well Autodesk's Revit (BIM), in conjunction with two of the most used energy modeling programs (BEM) known as DesignBuilder and Virtual Environment (IES-ve), were integrated in terms of interoperability, including location and weather files, geometry, construction and materials, thermal zones, occupancy operating schedules, and HVAC systems. All misrepresented data during the interoperability process were identified, followed by benchmarking between the BIM-based energy modeling simulation outcomes and the actual energy consumption of the case study, to assess the reliability of the process. The investigation has revealed a number of interoperability issues regarding the BIM data input and BEM data interpretation. Overall, BIM-based energy modeling proved to be a promising tool for sustainable and low energy building design, however, the BIM to BEM process is a non-standardized method of producing building energy models as it varies from one modeler to another, and the BIM to BEM process. All these might slow down any possible application for the process and might cause some uncertainties for the professionals in the field applying it.

Lifecycle Management

Buildings lifecycle management is an area of great interest. Due this, the R&D is being promoting worldwide looking for new effective maintenance tools and methodologies. In this scenario there are two development lines whose convergence can bring great advances in this area: Asset Management (AM) and Building Information Modeling (BIM). BIM models are transforming the way buildings are conceived, designed, constructed and managed. But current use of BIM concentrates on preplanning, design, construction and integrated project delivery of buildings and facilities, rather than maintenance and building operation management. Asset Management tools, including Facilities Management (FM), and application frameworks provide the approach and required elements to get more efficiency and efficacy in the building lifecycle management. This chapter introduces the application of AM for building and how the development of BIM models is the key element to allow its effective implementation.
