Despite previous research efforts, there is still a gap concerning the multidimensional nature of their integration. Hence, this study aims to fill the mentioned knowledge gap through exploring and comparing the challenges, enablers, techniques as well as benefits of integrating LC with BIM and sustainability in building construction projects. Design/methodology/approach A systematic literature review was conducted to fulfill the purpose of this study. Findings The findings reveal and compare the challenges, enablers, techniques and benefits of integrating LC with BIM and sustainability in building construction projects. The results suggest that there are eight common challenges for integrating LC with BIM and sustainability, including high initial cost, lack of collaboration, lack of professiona...

The former one’s considerable advantage was a common understanding and set of practices (e.g., the critical path method for scheduling), which seems to be a goal to achieve in the later one. In this regard, the combination and integration of best practices, tools, and techniques in construction project delivery can be considerably helpful for benefiting from their advantages and covering their limitations. Thus, this study aims to develop a conceptual framework for lean and sustainable project delivery in building construction projects. To do so, a systematic literature review was carried out, through which 230 studies were located and analyzed via thematic analysis to realize the purpose of this study. The findings present a conceptu...

To ensure that the requirements for the indoor conditions and the ice temperature will be fulfilled, the HVAC and the ice rink systems have to be optimised with the interactivity of each other in mind. This challenging optimisation task is solved with advanced and effective multiphysics and CFD simulation tools. The heat and moisture balance of the arena is solved dynamically with multiphysics tool with 3D simulation of ice rink heat balance. CFD (Computational Fluid Dynamics) is used to support the design of air distribution and indoor thermal conditions. These calculations form the bases for the MEP design solutions where integration of heating, cooling, dehumidification, energy conservation and the use of outside energy resources are optimised to achieve the most economical investment.

TERMA project (2004-2006) developed several concepts to integrate thermal mass of hollow-core slabs and air-conditioning systems to meet the requirements of energy efficiency and good indoor conditions. The development was done by using advanced modelling and simulation methods. Thermal behaviour of the hollow-core slab integrated to ventilation was also measured in laboratory. Simulation models were validated against these measurements. The basic strategy for thermal mass utilisation during cooling season is cooling down the slab during unoccupied time by night ventilation to decrease the day time cooling need in the room. By active use of thermal mass of hollow-core slabs the indoor temperature can be reduced at least 2ºC. The active use of thermal mass showed 4..10% savings in heating energy, 46..47% savings in cooling energy and 12..23% savings in fan en...

The promising performance results of construction projects with collaborative delivery models are mostly attributed to their behavioral elements (e.g., mutual trust), which have been frequently mentioned in the literature. However, the interrelationships between these behavioral elements as well as the enablers of these behavioral elements are two knowledge gaps which need to be addressed. Therefore, this study aims to fill the mentioned knowledge gaps by addressing the behavioral elements of collaborative project delivery models from analytical and conceptual perspectives. To do so, a systematic literature review was undertaken by locating 201 relevant studies and reviewing them. This was followed by the thematic analysis of the obtained research data and the development of a model for meeting this study’s objectives. The findings pres...
