A CBEI team of researchers led by Jim Braun of Purdue University has successfully implemented the use of virtual sensors within a low-cost microprocessor.
A virtual sensor system (compatible with the VOLTTRON platform) has been designed and an initial
prototype has been tested.
The session, conducted by Covestro LLC and Oak Ridge National Laboratory, aims at identifying best practice recommendation for energy-efficient, cost-effective retrofit solutions for the interior of existing masonry wall system for commercial buildings. The target market identified is climate zone 4 & 5.
Understand the purpose of Building Re-tuning; Discover the potential energy and cost savings; Understand the leading opportunities for energy savings as a result of building re-tuning; Assess your organization’s readiness to conduct building re-tuning.
As a member of the Subtask 5.4 Indoor Environment Quality (IEQ) assessment team, the Center for Building Performance and Diagnostics (CBPD) at Carnegie Mellon University conducted a Post Occupancy Evaluation (POE) for Building 661 in Navy Yard, Philadelphia, PA, on July 10th, 2015.
The Pattern Matching Principal Component Analysis (PCA)-based fault detection method developed by CBEI consistently detected faults at a detection rate of 94% with no false alarms.
Buildings consume over 40% of the total energy in the U.S. Over 90% of the buildings are less than 50,000 square feet in size. These buildings currently do not use building automation systems to monitor and control their building systems.
RTUs serve 60% of commercial floor space and account for about 150 Terawatt hours of annual electrical usage (~1.56 Quads of primary energy) and about $15B in electric bills in the US.
Energy efficiency in existing buildings is most often addressed by upgrading outdated lighting equipment and adding efficient equipment to the heating and cooling systems because of low risk and short financial payback.
The Asset Score Tool (AST) is a quick and easy way to determine the overall energy efficiency of your building's physical characteristics and corresponding energy consumption independent of occupant behavior.
