The paper describes the testing of a portable scanning system (RAPMOD), which is worn like a backpack and allows the user to walk through a building to collect essential energy-related data. From this walkthrough, the system collects data required for an energy model of the building using laser scanners, infrared scanners and cameras and converts these data into .idf format for use in EnergyPlus. The energy model includes the geometry of interior and exterior surfaces, window U-values, lighting levels, equipment levels and occupancy for each room. RAPMOD will be extended to include HVAC recognition in a subsequent phase of development. The main goal is to reduce the cost and skill level required to create energy simulation models for deep retrofit assessments, energy audits and retro commissioning for existing buildings through rapid and accurate energy model creation.
