{"title":"Improving the Predeveloped Local Ecology: Maximizing Condensate Collection through Strategic Building Operation","authors":"Joshua D. Brooks, Jung‐Ho Lewe, S. Duncan, Dimitri Mavris","doi":"10.1061/jswbay.sweng-476","DOIUrl":"https://doi.org/10.1061/jswbay.sweng-476","url":null,"abstract":": This work demonstrates how a water and energy sustainable building ’ s heating, ventilation, and air conditioning (HVAC) system may be operated to maximize condensate production while upholding user thermal comfort and energy consumption requirements. A physics-based HVAC condensate model was presented and validated against operating data from the Kendeda Building for Innovative Sustainable Design (KBISD), a 3,437 . 4 -m 2 ( 37,000 -ft 2 ) academic building on the Georgia Institute of Technology ’ s Atlanta campus. A sensitivity study of the HVAC condensate production and power consumption was performed. Metamodels were developed to concisely yet accurately represent the physics-based model, and these were used as the basis of an optimization exercise to identify competitive operating conditions for maximizing condensate production. The case studies included here found optimized HVAC system operation strategies to produce up to 708% more condensate. The demonstrated approach may be reproduced by system operators or building automation systems to increase condensate production without sacrificing building system-level energy and thermal comfort requirements. DOI: 10.1061/ JSWBAY.SWENG-476. © 2023 American Society of Civil Engineers. Practical Applications: This work demonstrates how a building ’ s heating, ventilation, and air conditioning (HVAC) system may be operated to increase the amount of water, or condensate, which may be pulled out of the air and collected. A simple engineering model is presented and verified against real-world data. This is used as the basis for an optimization approach that allows operators to make strategic, mathematically substantiated decisions to impact the amount of condensate collected and the power required to do so. In addition, the use of so-called metamodels for reducing complex engineering models or systems into simple mathematical representations is exemplified for increasing the speed of the analyses performed in this work. These metamodels may be used to represent HVAC or other building systems and allow for optimization efforts similar to those presented herein or potentially model predictive control. The case studies discussed in this work bring the optimization approach and metamodels together to demonstrate how a building may theoretically be operated to increase its condensate production by 708% within reasonable power requirements and without sacrificing the comfort of the building ’ s occupants.","PeriodicalId":44425,"journal":{"name":"Journal of Sustainable Water in the Built Environment","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42812145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three sizes of hydraulically isolated bioretention units were tested in duplicate with changes in aspect ratio of length from inlet wall by doubling successive length from smallest (3.7 m) to largest (14.9 m) while width remained the same (7.1 m). The watershed areas were nominally the same, resulting in watershed-to-surface area ratios of 5.5:1 for largest duplicate units, 11:1 for the middle units, and 22:1 for the smallest. Each unit was instrumented for continuous monitoring with water content reflectometers (WCRs) and thermistors with data collected since November 2009. The bioretention units were filled with planting media initially comprising 90% sand and 10% sphagnum peat moss by volume and approximately 99% and 1%, respectively, by weight. These units were then planted between May and November of 2010 with a variety of native grasses, perennials, shrubs, and trees that were tolerant to inundation, drought and salt. In late 2012, a survey of the shrubs planted in these bioretention units was performed. The published results of the combined analyses of moisture content, rainfall, and size of shrubs indicated that the smaller units had superior shrub growth due to the more frequent saturation of the root zone as measured by WCR, while the plants in the largest units, particularly away from front wall where runoff entered, potentially relied on direct rainfall only. Starting in 2017, additional monitoring was performed in these units, including chemistry analysis by loss on ignition and total phosphorus of the engineered planting media and an additional survey of the plants. As in the previous study, plants did better in the medium (11:1) and small (22:1) bioretention units than in the largest units (5.5:1), and there was greater buildup of organic matter and phosphorus in the smaller units. One species of grass that dominated the two largest bioretention units away from the inlet was drought tolerant, which indicated that plants in these units relied on rainfall rather than stormwater runoff. Oversized units did not completely use the stromwater control volume, and many of the other original plantings grew slower or were less widespread in comparison to plantings in that smaller units that flooded more frequently and achieved greater growth.</p><p><strong>Practical applications: </strong>Defining the size of stormwater controls can be difficult because there are often multiple objectives imposed on the final design of these structures, including safety and flooding. Results presented here would indicate that if the objective is to create a bioretention area with healthy vegetation, undersized controls may be acceptable because undersized infiltrating controls will have healthier plantings and infiltrate throughout the storm.

This study aimed to evaluate the effectiveness of different SCM design scenarios and implementation alternatives on exceedance levels and volumes of streamflow at the watershed scale. For this purpose, a process-based block-connector model of Sligo Creek, an urban watershed (29 km²) in the suburbs of Washington, DC, was used to study the effects of SCM system design on the stream hydrograph. The watershed has 34% impervious area (IA), which was discretized into 14 similar-sized subwatersheds, each consisting of pervious and impervious surface areas. Each subwatershed was compartmentalized with the representative overland flow, unsaturated flow, groundwater blocks, and links to main channel segments. The model was calibrated and validated to existing conditions using a 3-year time series of observed flow data. Afterward, a predevelopment simulation was configured. Three SCM unit designs and IA diversions through the SCM retrofit system were simulated. The three unit design scenarios represented a simple pond with surface storage and overflow or SCMs that infiltrate with an engineered soil layer and with or without an underdrain pipe. Differences among the model simulations were evaluated using flow exceedance probability curves. The area of the SCM system was modeled as 5% of the IA retrofit. Three implementation levels, including 10%, 50%, and 90% of the IA diverted through SCMs, were considered for each SCM unit design. The results showed that at least a 50% retrofit of runoff from IA watershedwide would be needed to achieve similar predevelopment base flows and peak flows. Intermediate flows could not be matched but were closest for the infiltration with the underdrain pipe design scenario. It was also found that concentrating the SCMs in the lower portion of the watershed resulted in more effectively achieving the predeveloped exceedance curves than uniform SCM implementation. The results are relevant to planning-level decisions that depend on effectiveness predictions of different SCM unit designs and implementation alternatives in developed watersheds.</p>","PeriodicalId":44425,"journal":{"name":"Journal of Sustainable Water in the Built Environment","volume":"9 1","pages":"1-15"},"PeriodicalIF":1.9,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10494882/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10608368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
