During preliminary energy analysis, massing and orientation are energy reduction strategies that can best help in reducing the energy load in the new building construction project. Massing and orientation refer to the shape, size, and direction of the building, which affect the amount of solar heat gain, daylight, and natural ventilation that the building receives. By analyzing the massing and orientation of the building, the project team can optimize the design to minimize the heating, cooling, and lighting energy demand, and enhance the thermal comfort and indoor environmental quality of the building. The LEED v4 Reference Guide for Building Design and Construction states that "the project team should use the results of the analysis to inform the owner’s project requirements, basis of design, and design documents"1. The other options, such as green roof, site conditions, and programmatic and operational parameters, are not energy reduction strategies, but factors that influence the energy performance and demand of the building.
