BRT is a systematic process to identify and correct building operational problems that lead to energy waste. It is implemented at no- or low-cost other than the labor required to perform the Re-Tuning process.
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.
FREE online training program on U.S. EPA’s ENERGY STAR Portfolio Manager tool and building information collection. 4 interactive training modules (free to public).
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.
Designed for energy optimization of building retrofit projects. Applicable to new buildings and other projects. Empire State Building Example: Display the relevant metrics (here it’s NPV and CO2 savings). Include uncertainty and sensitivity about future projections.
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Energy efficiency in existing buildings is most often addressed by upgrading outdated lighting equipment and adding efficient equipment to the heating and cooling systems because of low risk and short financial payback.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.
Performance-based (also known as outcome-based) codes set standards based upon buildings’ actual energy use, rather than on compliance with stipulated technology or design features. For example, a performance-based code would require meeting specified energy use intensity, while a standard, prescriptive code would stipulate a minimum wall insulation level among other specific measures.
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.
