Final Project Report for DPD, Inc. Office Building in Lansing, Michigan

Research output: NRELTechnical Report


The National Renewable Energy Laboratory participated with DPD, Inc., in the thermal analysis of buildings constructed using concrete with recycled materials in the aggregate. This project was part of a Phase II Small Business Innovative Research grant to determine how the thermal properties of concrete can be 'tuned' for use in passive solar buildings. DPD Inc. and Michigan State Universitydeveloped techniques to alter the thermal properties of concrete by introducing recycled materials into the aggregate. Two office/retail buildings were built in Lansing, Michigan for this research. The objective of NREL's involvement was to evaluate the effects of concrete thermal properties on the building performance through energy simulations and monitoring. This report presents a summary ofwork accomplished on this project, including a predesign analysis of the concrete properties and building designs as well as energy performance analysis after construction. The test results were used to calibrate computer models that were later used to predict long-term performance of the buildings.
