CBEI performed a major retrofit of their headquarters. This report provides early lessons learned from the integrated design process.
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.
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.
Energy efficiency in existing buildings is most often addressed by upgrading outdated lighting equipment and adding efficient equipment to the heating and cooling systems because of low risk and short financial payback.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 energy use in commercial buildings is not constant. It changes with the seasons, from year to year, as tenants come and go, and with changes to building components. Building science researchers know that the energy performance of commercial buildings declines over time – different parts of the system start to age and building occupants invariably alter the “optimal” settings.
