Since water reuse consumes energy, water management requires careful analysis of energy implications. To this end, we study the energy-water nexus in a multi-building campus with a water delivery network that spans multiple grades (such as potable, reclaimed sewage, etc). Using data collected over several months, we answer these questions: (i) What are the trade-offs between the external water footprint of a campus and its internal energy footprint of water? (ii) Are improvements in either footprint realizable in practice? (iii) Does reducing the consumption of one water grade have more impact on the energy consumption than other water grades? (iv) Does rainwater harvesting help reduce a facility's energy footprint? We construct a multi-grade logical flow network with a per-link cost model for energy derived from the measured data. Under the constraint that demands are always met using the existing supplies, we optimize this flow-network for individually minimizing internal energy consumption of water and external water intake. Our study reveals the following: (i) minimizing external water footprint does not correspond to minimizing the internal energy footprint of water; (ii) demand reduction of different water grades impact the energy and water footprints differently; Contrary to intuition, reduction in second grade water demand yields highest reduction in water footprint while reduction in first grade water demand yields higher reduction in energy; (iii) Rainwater harvesting (RWH) can significantly reduce the energy footprint of a campus water network with sewage re-use. Our results show a potential for improving the operating condition of the campus's water network that can reduce the energy consumption by nearly 56 MWh (10.5%) and 99.6 MWh (18%) annually without and with RWH respectively.","PeriodicalId":184274,"journal":{"name":"Proceedings of the 5th ACM Workshop on Embedded Systems For Energy-Efficient Buildings","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124552950","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}

While heating, ventilating and air-conditioning (HVAC) system accounts for 40% of the total energy consumption in a commercial building, the concern of occupants comfort is always prior to energy consumption. However, the operation of building management system (BMS) does not consider occupants' actual perception, and lacks channels for occupants' feedback. Indoor air quality (IAQ) has been vigorous studied in the past decades due to its importance to worker's health and productivity, however, sick building syndrome (SBS) is still commonly found in occupants, where they experience acute health and discomfort after working in buildings for a period of time. Yet, there is currently no conclusive explanation to account for the SBS, thus it is hard to carry out effective measures without tracing the root cause. In this demo, we show our innovative design of IAQSense system. The system aims to enhance the air quality of buildings using participatory sensing approach. By exploiting the sensors data of BMS with occupants feedback, IAQSense helps identify the environmental factors that causing SBS and enhance the air quality of buildings.","PeriodicalId":184274,"journal":{"name":"Proceedings of the 5th ACM Workshop on Embedded Systems For Energy-Efficient Buildings","volume":"265 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116185190","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}

Thus detecting and diagnosing anomalies in the building's energy use is an important problem. The existing approaches either retrieve limited information about the anomaly causes, or are difficult to adapt to different buildings. This paper presents an easily adaptable diagnosis approach that exploits the building's hierarchy of submeters, i. e. information on how much energy is used by the different building equipments. It computes novel diagnosis results consisting of two parts: (i) the extent to which building equipments cause abnormal energy use, and (ii) the extent to which internal and external factors determine the energy use of building equipments. Computing such diagnosis results requires an approach that can predict the energy use for the different submeters and that can also determine the factors that influence the energy use. However, existing building approaches do not meet these requirements. As a remedy, we propose a novel approach using the generalized additive model (GAM), which incorporates various exogenous variables affecting building energy use, such as weather conditions and time of the day. Our experiments demonstrate that the proposed method can efficiently model the impact of different factors and diagnose the causes of anomalies.","PeriodicalId":184274,"journal":{"name":"Proceedings of the 5th ACM Workshop on Embedded Systems For Energy-Efficient Buildings","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122005149","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}

Emonix is designed with our custom energy sensing hardware and integrated communication units to be efficiently mounted in breaker panels of buildings. In contrast to plug-based monitoring systems, this approach is less intrusive to users because it does not intrude on their physical space, yet it still provides fine-grained real-time energy data in both space and time. The Emonix hardware platform is open, modular, and extensible. It provides an accessible data and configuration API for users, and we believe it is useful to the broad community. To demonstrate the usefulness of this platform, we have deployed this infrastructure on two campus dormitories covering 60 rooms and 120 residents. We have been operating this infrastructure as an energy monitoring service for the residents for more than four months to help them understand their consumption patterns at different timescales. Our results indicate significant temporal variations in energy consumption patterns at different time scales, and that a small fraction of occupants can consume a disproportionately large amount of energy in such buildings.","PeriodicalId":184274,"journal":{"name":"Proceedings of the 5th ACM Workshop on Embedded Systems For Energy-Efficient Buildings","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133005965","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}

A key inhibitor to the widespread adoption of such demand response policies at the consumer grade appliances level for intelligent building energy management, is the inability of smart plugs/sensors to efficiently communicate and control the power consumption. However since they already connected with the power grid, a natural question arises, whether the power consumption telemetry can be communicated over existing mains wiring. The use of existing wiring produces a simple and cost-effective attractive solution, and avoids many issues observed with wireless mesh networks, such as islands and bottlenecks and helps vacate the increasing congested spectrum. In this paper we explore the feasibility and efficacy of Powerline Communications (PLC) as a backbone of wireless communications in a home environment, both for high-bandwidth and low-bandwidth intensive applications. In this demo we show several state-of-the-art PLC modems' behavior using end-to-end measurements and their performance, throughput and noise characteristics.","PeriodicalId":184274,"journal":{"name":"Proceedings of the 5th ACM Workshop on Embedded Systems For Energy-Efficient Buildings","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127679980","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}

For a retail business spread across several stores, it is important to identify the correlations between cost, energy, operations, and location. To this end, we present a measurement-based analysis of energy and operations data gathered from 201 stores of a leading retail chain over a two year period. We employ statistical techniques and unsupervised learning to understand the inter-relationships across the various dimensions. Specifically, we find that: (i) The well-known Pareto cost-benefit principle (or the eighty-twenty effect) does not hold when considering the energy consumption as cost with customers served and store area covered as the benefits; (ii) After accounting for the time-of-day effects, sales counts do not affect energy consumption statistically, while ambient temperatures do so; (iii) Stores that exhibit a greater degree of energy proportionality have larger areas; and (iv) Opportunities for improvements exist in reducing the energy cost of operations. Many stores switch their operations on well ahead of their opening times. The average annual energy savings that could potentially be achieved across 201 stores if their operations are in tune with their opening time is roughly 8.2 GWh (2.5%). These savings can be achieved with just changes in operational procedures with zero capital investment.","PeriodicalId":184274,"journal":{"name":"Proceedings of the 5th ACM Workshop on Embedded Systems For Energy-Efficient Buildings","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124622276","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}
