Individual students in two different sections of an undergraduate civil engineering laboratory were tasked with preparing three professional-quality laboratory reports. The teaching assistant and/or instructor used established criteria to grade the first two reports prepared by students in one section. The first two reports prepared by students in the other section were peer evaluated by assigned fellow students within the same laboratory section using identical grading criteria. The peer evaluated section had a higher class average than the teaching assistant/instructor graded section on the fist two reports. The third report prepared by students from both sections was graded by a professional educator/architect without knowledge of a student's class section. The peer evaluation students also had a higher class average on the third report, suggesting that the peer evaluation process may have positively contributed to those students' writing skills.

Abstract:The cross-disciplinary nature of energy-efficient building design has created many challenges for architecture, engineering and construction instructors. One of the technical challenges in teaching sustainable building design is enabling students to quantitatively understand how different building designs affect a building's energy performance. Concept based instructional methods fall short in evaluating the impact of different design choices on a buildings' energy consumption. Building Information Modeling (BIM) with energy performance software provides a feasible tool to evaluate building design parameters. One notable advantage of this tool is its ability to couple 3D visualization of the structure with energy performance analysis without requiring detailed mathematical and thermodynamic calculations. Project-based Learning (PBL) utilizing BIM tools coupled with energy analysis software was incorporated into a senior level undergraduate class. Student perceptions and feedback were analyzed to gauge the effectiveness of these techniques as instructional tools. The findings indicated that BIM-PBL can be used to effectively teach energy-efficient building design and construction.
