Going Solar in Lafayette Published LAFAYETTE by the City of Lafayette Summer 2015 VVISTASISTAS Vol. 25, No.3 LET THE SUN SHINE IN: Going Solar in Lafayette ake a drive around Lafayette and you’ll see more and more homes with solar panels up on the roof. You might Thave even considered them for yourself but you weren’t sure if solar panels work for you. Fortunately, three new tools can help answer that question. Project Sunroof The first is an impressive new mapping application launched by Google in mid-August called Project Sunroof. Tapping its trove of satellite imagery and the latest in artificial intelligence, the company’s new online service instantly estimates how much you’ll save by installing a roof full of solar panels. After creating a 3-D model of your roof, the application cal- culates how much sun will hit those solar panels during the year and how much money the panels will save you over the Last December, when the Lafayette City Council autho- next two decades.

It is the case also for our university – the Slovak University of Technology in Bratislava and its faculty – the Faculty of Informatics and Information Technologies. Close connection of research and education leads very naturally to an active participation of students in research. This holds not only for students of the doctoral study, where research is a substantial part of their study and one of their principal activities. A participation of students in research is “going down” to students of the master’s and even the bachelor study. Universities of technology have a long tradition of students participating in a research work where they have to apply their theoretical knowledge.

  • Project Sunroof Data Explorer: a Description of Methodology and Inputs
    Project Sunroof data explorer: a description of methodology and inputs Last updated: February 2017 Background Project Sunroof puts Google's expansive data in mapping and computing resources to use for people and organizations interested in solar power, helping illustrate the potential of solar power for a single house, and with the introduction of the data explorer, the potential of solar for zip codes, cities, counties and states. Project Sunroof wants to make it effortless to understand the potential of solar power. The data explorer estimates the technical potential of solar power for a region chosen by the user. Technical potential of a resource is defined as the amount of energy that the resource can generate, irrespective of financial or societal constraints. Various different definitions of solar technical potential appear, resulting in estimates that can differ by 25% or more. This detailed methodology description focuses on the data explorer and the approach to arrive at estimates of technical potential. The description here is generally consistent with the approach taken for single-house savings estimator, but this methodology does not cover all elements of the savings estimation at the single-house level. Methodology Summary Project Sunroof estimates the amount of sun hitting a rooftop using 3D models derived from aerial imagery. The 3D models allow estimation of shading for every point on a roof, for each possible position of the sun in the sky. The 3D models also enable the estimation of the amount of available space for solar panels, including the pitch and azimuth of each roof plane. Including typical weather data enables estimates of energy production from panels placed in the viable roof space.

In this paper, we present an approach to estimate the solar potential of rooftops based on their location and architectural characteristics, as well as the amount of solar radiation they receive annually. Our technique uses computer vision to achieve semantic segmentation of roof sections and roof objects on the one hand, and a machine learning model based on struc- tured building features to predict roof pitch on the other hand. We then com- pute the azimuth and maximum number of solar panels that can be installed on a rooftop with geometric approaches. Finally, we compute precise shading masks and combine them with solar irradiation data that enables us to estimate the yearly solar potential of a rooftop. arXiv:2106.15268v1 [cs.CV] 28 May 2021 1 Introduction The 21st century is characterized by an ever-increasing energy consumption and greenhouse gas emissions that are contributing to climate change in an unprecedented way.

  • Climate Action Plan, Which Includes and Expands on the Measures and Goals Introduced in Our Preceding 2010 Plan
    Adopted March 19, 2018 This page left blank intentionally Mayor’s Statement To all who live, work or sojourn in Piedmont: I am pleased to introduce Piedmont’s second Climate Action Plan, which includes and expands on the measures and goals introduced in our preceding 2010 Plan. With the recognition that some measures may have an up-front fiscal impact on the City and its residents, this revised version of the Climate Action Plan is intended to serve as a means to continue the City’s commitment to keep reducing our carbon footprint as the signs of climate change have grown. Recognizing the global impact of Climate Change, the City of Piedmont joined over 7,000 local governments as part of the Global Covenant of Mayors in 2016. As part of this commitment, cities pledge to consistently measure, create goals for, and reduce greenhouse gas emissions. Since 2005, the Piedmont community has reduced its in-boundary carbon footprint from 48,818 metric tons of carbon dioxide equivalent (CO2e) to 38,498 MT CO2e, a reduction of 21%. This reduction was made possible in part by individual and collective actions taken by our community, but mostly, as a result of lower natural gas use during the very warm winters of 2014 and 2015. Meeting our goals has allowed us to set new targets, more ambitious than the previous ones and in sync with those recently set by the State. Our new goal, a 40% reduction in emissions from the 2005 baseline by 2030, sets Piedmont on a path to successfully reduce its emissions by a substantial amount.
