Using Bioretention Retrofits to Achieve the Goals of Virginia's New Stormwater Management Regulations
Virginia's new stormwater regulations involve the use of the Runoff Reduction Method (RRM), which requires the product of the peak flow rate and runoff volume (Q*RV) from the one-year storm event in the post-development condition to be reduced to eighty percent of the pre-development Q*RV to …

Deep Energy Retrofits Using the Integrative Design Process: Are they Worth the Cost
… Global Initiative identified existing building retrofits as an integral component to achieve a 75% reduction in greenhouse gas emissions in the United Sates by 2050 (Fluhrer, Maurer, & Deshmukh 2010). However, this will require energy efficiency retrofits for existing buildings to be deployed …

Optimizing resilience : performance based assessment of retrofits for wood-frame housing in San Francisco
… the considered wood-frame building with applied retrofits, and that minimization of lifetime losses corresponds to augmented retrofit costs. The research concludes with a discussion on prescribing retrofits for a building's longevity versus recommendations for short-term solutions that only call …

Simulation and Assessment of Long-Term Stormwater Basin Performance under Real-Time Control Retrofits
The use of real-time control (RTC) as an adaptation technique for improving existing stormwater systems has been gaining attention in recent years for its ability to enhance water quality and quantity treatment. A case study RTC retrofit of seven existing detention basins was simulated for a small …

Assessment of Predictive Real-Time Control Retrofits on Stormwater Basin Performance in an Urban Watershed
The potential real-time control (RTC) has to improve the performance of existing stormwater management systems is a topic of increasing interest as hydraulic and hydrologic modeling capabilities proliferate. The benefits of incorporating precipitation forecast data into a RTC algorithm to allow for …
