\r\n\r\n\r\nThe sensor would send the current consumption to a server, where further analysis and visualisation can be done. As consumption heavily depends on the weather and temperature it would be wise to also track weather data from the region.\r\n\r\nA funny and playful visualisation would help the residents from the house to save CO2 and money.\r\n\r\nData could also be compared between houses on a larger scale, a very interesting data set for the city, to prioritize and stear the replacement of such heating in the city. If we know the number of appartments or total living space, a map could show which houses are well isolated and which ones would eg need some adjustments, or would be replaced first to have the biggest impact.\r\n\r\n![](\"https://raw.githubusercontent.com/2ni/makezurich-gasconsumption/main//images/zh.png\")
\r\n\r\nThinking further the consumption could also be estimated for the future depending on weather forecast.\r\n\r\n### Some data\r\nI live in an (old) house with 3 residential appartments and 2 offices. Last winter we roughly consumed 13 tons of CO2 or 4000m3 of gas! For a certain period of time 2 parties where well motivated, which showed a reduction of 35% compared to last year. Later on, only one party was palying the game seriously, which still led to a reduction of 10%.\r\n\r\n![](\"https://raw.githubusercontent.com/2ni/makezurich-gasconsumption/main//images/gasconsumption-q4-2022.png\")

We unlock the full potential of solar energy by maximizing efficiency and output, ensuring that your solar panels are always aligned to capture the maximum amount of sunlight.\r\n\r\nOur Solar Potential Analysis & Optimal Placement Algorithm takes into account crucial data such as energy consumption, sunlight availability, building characteristics, and geospatial information. By leveraging this data, our intelligent system optimizes panel positioning, tilt angles, and tracking, resulting in maximum energy generation and savings. We even strategically place panels alongside heat pumps to enhance efficiency and benefits.\r\n\r\nBut our innovation doesn't stop there. SunSync provides an intuitive Visualization and Decision Support Tool that seamlessly integrates analyzed data, offering optimal solar panel placement recommendations. Through interactive maps, graphs, and metrics, stakeholders can visualize solar potential, energy consumption, and potential cost savings.\r\n\r\nPublic engagement and awareness are core to our mission. SunSync's dashboard features customizable parameters and scenario exploration options, allowing users to tailor the analysis to their specific needs. Additionally, our tool showcases the potential impact of solar panels in your area, highlighting reduced carbon emissions and energy cost savings.\r\n\r\nTo address storage challenges, we incorporate IoT technology. Our IoT device combines photovoltaic panels with heat pumps, enabling surplus energy utilization. By redistributing excess energy within the community, we foster a sustainable and collaborative energy ecosystem.\r\n\r\nWith SunSync, you not only optimize your solar panel system, but you also gain valuable insights into your energy consumption patterns. Our user-friendly interface provides seamless monitoring, control, and real-time issue detection and resolution.\r\n\r\nJoin us in the solar revolution and experience the future of clean energy optimization with SunSync. Let's harness the power of data and IoT to unlock the full potential of solar energy, driving down costs, reducing carbon footprint, and making a meaningful impact on the environment.\r\n\r\nTogether, let's shape a greener and more sustainable future.\r\n","maintainer":"selin_arpaci","name":"Sunsync","phase":"Find","progress":5,"score":33,"source_url":"","stats":{"commits":0,"during":17,"people":2,"sizepitch":2623,"sizetotal":2677,"total":17,"updates":14},"summary":"Harnessing the Power of the Sun for Sustainable Future ","team":"selin_arpaci, julia_larikova","team_count":2,"updated_at":"2023-06-12T07:29","url":"https://now.makezurich.ch/project/92","webpage_url":"https://bucketeer-036aa605-c047-4623-8610-f1764b90cf98.s3.amazonaws.com/makezurich/15/0ESHXWH4TKV8FF00O01YXOFE/compressed_PDF_file.pdf"},{"autotext":"","autotext_url":"","category_id":50,"category_name":"2.
