The use of an integrated design process is encouraged or required by a number of green building certifications, but many design and construction professionals have very limited knowledge about how to practice integrated design. This paper compares the integrated design process as practiced on one design project in mid-sized urban center in the Midwestern United States to the process outlined in...

A simple, green and efficient method for synthesis of 2,4,5-trisubstituted imidazoles is described via three-component cyclocondensation of benzil or benzoin, aldehyde and ammonium acetate by using the nano SiO2-supported ferric hydrogen sulfate (FHS/SiO2), as a catalyst, under solvent-free conditions. The nano SiO2 support and catalyst were characterized by X-ray diffraction (XRD), transmissio...

projects scheduling by the project portfolio selection, something that has its own complexity and its flexibility, can create different composition of the project portfolio. an integer programming model is formulated for the project portfolio selection and scheduling.two heuristic algorithms, genetic algorithm (ga) and simulated annealing (sa), are presented to solve the problem. results of cal...

Previous research on risks in complex green building projects has been mainly focused on what the risks are and how they may impact on project objectives. Such studies have tended toward an inward looking perspective that treats risks in isolation from one another. In reality, most risks are interrelated and associated with internal or external project stakeholders. To address this research gap...
