This research explores the installation of solar panels directly onto playground equipment as a way to promote the adoption of solar energy through photovoltaics. As children are accustomed to interacting with solar technology from a young age, they will likely come to expect solar and other more sustainable types of energy throughout society, both in public and in private. These expectations will further fuel the solar industry, lower prices, and increase the adoption and use of renewable energy sources in the future. Data is presented of the potential energy production of 11 parks in Provo, Utah, with a cost-benefit analysis of installing panels on those playgrounds. Although the energy produced at each park is relatively small, the benefits suggest it is feasible and becomes more attractive and impactful when considering the increased awareness it provides of energy usage, familiarity with a sustainable technology, and likely future adoption by the next generation.","PeriodicalId":231217,"journal":{"name":"2017 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126334718","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}

In this paper, the probability that SIRES fulfills these needs, or in short, Need Fulfillment Probability (NFP), is estimated for four different weather conditions where insolation and wind resources are varied. NFP of SIRES is highest on a high wind sunny day and is estimated to be 0.9627.

As the Bridge infrastructure has aged towards the requirement for effective monitoring, the Structural Health Monitoring (SHM) of bridges has become increasingly significant. Currently, in the Philippines, the method for structural integrity evaluation of bridges is limited to on-site visual inspection. Moreover, visual inspections have proven to be deficient in assessing the actual condition of a certain bridge. For this study, SmartBridge Sensor Nodes were utilized for SHM to further evaluate the health of a bridge. Acceleration readings gathered by the sensor shall aid indicate the actual health of the bridge in which visual inspections are incapable of. To efficiently utilize the sensors, the methods of proper installation and location for placement of sensors on an existing concrete bridge with American Association of State Highway and Transportation Officials (AASHTO) Type IV Girders was determined.

However, the production of jet biofuels will have impacts on environment, economy and society simultaneously. Despite that a large number of studies have evaluated environmental impacts or techno-economic feasibility of aviation biofuels, very few studies took social aspects into consideration. Thus, this study seeks to provide a social sustainability evaluation for aviation biofuels with a supply chain perspective. Three potential jet biofuel supply chains, based on different feedstocks, i.e. sugarcane, eucalyptus and macauba, were analyzed in the context of Brazil. The assessment is performed mainly with a process-based approach combined with input-output analysis. A set of social sustainability issues, including employment, working condition, labor right, gender equity and social development, were evaluated in a quantitative manner. The results show the three supply chains lead to differentiated levels of social effects. The macauba-based supply chain generates the highest number of jobs and highest GDP value, whereas the eucalyptus-based supply chain offers more employment opportunities for women. In comparison, the sugarcane-based supply chain has relatively moderate social effects. For future work, the assessment of social sustainability needs to cover a wider range of social issues, in order to extend the comprehension of social sustainability regarding biofuels. Additional research is suggested to bridge the methodological gaps in social sustainability assessment.","PeriodicalId":231217,"journal":{"name":"2017 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"2017 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131825747","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}

Bridges are structures built to provide passage over a physical obstruction such as rivers, chasms or roads. The Philippines has a total of 8,166 national bridges as published on the 2015 atlas of the Department of Public Works and Highways (DPWH) and only 2,924 or 35.81% of these bridges are in good condition. As a result, PHP 30.464 billion of the 2016 budget of DPWH is allocated on roads and/or bridges maintenance alone. Intensive spending is owed to the present practice of outdated manual inspection and assessment, and poor structural health monitoring of Philippine infrastructures. As the School of Civil, Environmental, & Geological Engineering of Mapua Institute of Technology (MIT) continuous its well driven passion in research based projects, a partnership with the Department of Science and Technology (DOST) and the DPWH launched the application of Structural Health Monitoring, (SHM) in Padre Jacinto Zamora Flyover. The flyover is located along Nagtahan Boulevard in Sta. Mesa, Manila that connects Brgy. 411 and Brgy. 635. It gives service to vehicles going from Lacson Avenue to Mabini Bridge passing over Legarda Flyover. The flyover is chosen among the many located bridges in Metro Manila as the focus of the pilot testing due to its site accessibility, and complete structural built plans and specifications necessary for SHM as provided by the Bureau of Design, BOD department of DPWH. This paper focuses on providing a method to calibrate theoretical readings from STAAD Vi8 Pro and sync the data to actual MEMS accelerometer readings. It is observed that while the design standards used in constructing the flyover was reflected on the model, actual readings of MEMS accelerometer display a large difference compared to the theoretical data ran and taken from STAAD Vi8 Pro. In achieving true seismic response of the modeled bridge or hence syncing the theoretical data to the actual sensor reading also called as the independent variable of this paper, analysis using single degree of freedom (SDOF) of the flyover under free vibration without damping using STAAD Vi8 Pro is done. The earthquake excitation and bridge responses is subjected to earthquake ground motion in the form of ground acceleration or Peak Ground Acceleration, PGA. Translational acceleration load is used to simulate the ground motion of the time history analysis acceleration record in STAAD Vi8 Pro. Though sensors measure three axes simultatniously, SDAF will be used in the analysis since this paper focuses in the up and down movement of the bridge being inspected. Lastly, environmental factors such as wind and rainfall were all viewed as external elements. With this, upon calibration, these factors were corrected not to affect the readings of the sensors used in the study.","PeriodicalId":231217,"journal":{"name":"2017 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132035587","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}

However, several challenges accompany the deployment of solar PV for residential construction, such as determining an optimum size and layout design for best on-site system utilization in conformity to local roof sloping practices, especially in cold-climate regions. In addition, solar PV applications in high-latitude regions encounter other challenges, such as seasonal variations in daylight hours and in the sun's path, and soiling parameters such as snow coverage. These challenges result in a PV mismatch: (a) in winter, minimal PV-generated energy and high energy demand (due to space heating and hot water heating loads), and (b) in summer, PV over-generation and reduced energy demand. This paper aims to mitigate the impact of solar PV micro-generation and household loads on the utility grid by improving solar PV layout placement in order to maximize the system's load-match and minimize its grid interaction.","PeriodicalId":231217,"journal":{"name":"2017 IEEE Conference on Technologies for Sustainability (SusTech)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116259824","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}
