Seminar 37 - Use of Energy Modeling Tools to Support Building Asset Ratings: Screening Analysis, Simplified Modeling and Retrofit Analysis ✓ Most Recent

Track: Modeling Throughout the Building Life Cycle
Sponsor: 4.7 Energy Calculations
Chair: Chris Balbach, P.E., Associate Member, Performance Systems Development, Ithaca, NY

With more cities employing energy-related mandates as a vehicle to improve energy utilization in commercial and residential buildings, publicly available tools utilizing energy simulations, in the form of Asset Rating Systems, are being creatively used to triage and prioritize investment in infrastructure. A streamlined process that integrates benchmarking, energy audit, retro-commissioning and deep retrofits is critical to minimize implementation costs, facilitate adoption and move the market to scale.

1. Integration of Screening, Modeling, and Energy Audit
Nora Wang, Dr.Eng, PNNL, Richland, WA
This presentation demonstrates how the Asset Score provides a streamlined process for quick analyses of building portfolios, easy-to-use simplified energy modeling and in-depth energy audit through a single, integrated platform. The Asset Score allows users to quickly run batch analyses of a large number of buildings with seven easy-to-collect data points (aka Preview) or perform a full scale ASHRAE standard level 2 audit (aka Audit Template). Both Preview and Audit Template can be converted to simplified Energy Plus models for evaluation of the as-built physical characteristics of a building, independent of its occupancy and operational choices.

2. Driving Efficiency through Home Energy Ratings
Madeline Salzman, USDOE, Washington, DC
Commercial buildings are a likely first target of cities, but many jurisdictions have come to realize that single family homes offer substantial, and in some cases even greater, potential for energy and cost savings. That said, the single family market has its own set of challenges. Most homes are owned by single families, not corporations. Little data is available on existing homes. Housing stock varies considerably.

3. Energy Services Triage for Buildings
Greg Thomas, Performance Systems Development, Ithaca, NY
This seminar demonstrates how information extracted from Commercial Asset Ratings can be visually presented to help building owners set performance targets and engage service providers for further developing targeted workscopes aimed at likely areas of energy utilization improvement. When combined with Operational information such as that available from a Portfolio Manager score, the potential for a) retuning/retro commissioning services, b) capital equipment replacement and c) occupant/behavioral interventions can also be qualitatively assessed. A case study is used to demonstrate the principles in action.
