Global warming is causing an increase in the temperature of the atmosphere. (2011) have reviewed of several advanced cool materials systems usable to reduce the UHI. Environ. Over the entire year, on average for the whole city, the thermal solar panels would produce approximately 265 MJ/year/m2 of building and the PV panels 113 MJ/year/m2 of building. A simple parameterization of land surface processes for meteorological models. The aim of this paper is then to evaluate the impact of solar panels, known to be good for global warming mitigation, on the local climate, especially the UHI. Geosci. It is slowly destroying the ozone layer which is a protective layer in the atmosphere and protects us from the harmful rays of the sun. The thermal production is of course limited by the area of panels on the roof but it is also limited by the population in the building: it is not necessary to heat more water than required by the number of people who are going to use it. Environ. doi: 10.5194/gmdd-5-1295-2012, Lund, H. (2007). More theoretical than the others, solar radiation management is an approach that aims to block some of the sun's rays to reduce global warming. For example, although it is not the case in this paper, it is possible to have greenroofs with or without solar panels. 76, 1–14. For the energy balance of the roof, the most important key parameter will, of course, be the proportion of roof area occupied by the solar panels. However, the question of the ability of solar panels to contribute to the same goal is not addressed in these papers, and extremely few studies focus on, or even take into account, the effect of solar panels on the UHI. (2012) and Pigeon et al. The following simplifying assumptions are made: • An average temperature is still calculated for the roof, without distinguishing between the parts of the roof under or beside the panel. Rev. H  is the sensible heat flux from the solar panel to the atmosphere. It is then necessary to define what proportion of the roof area is required for thermal panels, and how much area remains available for PV panels. The production of solar energy in cities is clearly a way to diminish our dependency to fossil fuels, and is a good way to mitigate global warming by lowering the emission of greenhouse gases. However, what are the impacts of solar panels locally? They then perform an analysis of the impact of several types of roofs on sensible heat fluxes toward the atmosphere, but are unable to link these fluxes to the UHI, which needs to take all the buildings of the entire city into account. doi: 10.1016/j.buildenv.2011.06.012, Sims, R. E. H., Rogner, H.-H., and Gregory, K. (2003). Sust. In TEB, two different types of solar panels: thermal and photovoltaic (PV) are considered. 16, 1261–1282. It also has to be considered that, due to climate warming, the UHI impacts will become even larger than they are now (Lemonsu et al., 2013). (2013) have reviewed several research works analyzing strategies to mitigate the UHI, including changes in green spaces, trees, albedo, pavement surfaces, vegetation, and building types and materials. It is classically parameterized using the albedo of the solar panel (αpanel): SW↑panel = αpanelSW↓panel. Evaluation of building energy simulations with the TEB model against energyplus for a set of representative buildings in Paris. Historical Hausmannian buildings in the very center of Paris are roofed with zinc on top of wood, so their albedo is very high, set to 0.6. Received: 04 March 2014; Paper pending published: 31 March 2014; Accepted: 29 April 2014; Published online: 04 June 2014. In daytime, the presence of solar panels would decrease the air temperature by more than 0.2 K, especially in the dense suburbs, where the density of solar panels is the highest, due to both the high density of building and the fact that unlike the Haussmanian buildings of the city center, the suburban apartment and commercial buildings are flat roofed. The authors thank Colette Marchadier for her work in the MUSCADE and ACCLIMAT projects' management. The implementation of solar panels as a separate element of the urban surface energy balance system, as done here, allows a fine description of their impact on the underlying building energetics. Climatol. The TEB model will then be able to estimate the impact of solar panel implementation on the UHI at city scale, as well as the production of energy. (2003). On flat roofs, however, more space is available, and solar panels are taken to be installed on 50% of each roof. Urban Climate. doi: 10.1002/joc.3415, Elliott, D. (2000). We need to be responsible for our environment. Meteorol. A similar effect of dirt had already been found by Garg (1974), with attenuation of 10–20% for tilt angles between 45° and 30°. Increasing the supply of renewable energy would allow us to replace carbon-intensive energy sources and significantly reduce US global warming emissions. In 2005 a whopping 86 percent of energy used worldwide came from fossil fuel combustion, and right now in the United States, the number isnt much lower at about 85 percent. Keywords: urban heat island, solar energy, solar panels, cities, adaptation to climate change, Citation: Masson V, Bonhomme M, Salagnac J-L, Briottet X and Lemonsu A (2014) Solar panels reduce both global warming and urban heat island. 65, 229–244. Cities are warmer than the surrounding countryside, and this can lead to a health crisis during heat waves, as was the case in Paris in 2003 with 15,000 premature deaths (Fouillet et al., 2006) or in Moscow with 11,000 premature deaths in 2010 (Porfiriev, 2014). Most of our energy comes from burning fossil fuels, a process that emits carbon dioxide, a greenhouse gas (GHG). doi: 10.1016/S0160-4120(02)00130-7, Hernandez, R. R., Easter, S. B., Murphy-Mariscal, M. L., Maestre, F. T., Tavassoli, M., Allen, E. B., et al. 47, 3192–3203. 2. Materials needed solar panel installation. So, the power averaged over the year would be: Here, in order to better take the variability in production due to solar irradiation into account, instead of an annual mean computation, instantaneous production is considered in connection with the daily need for warm water. The products implicated were withdrawn from the market but this situation calls for a rigorous selection of products and contractors as well as for a maintenance plan of the installations. In this regard, the solar panels, even maybe thermal ones, would decrease the albedo of the city there, and might tend to increase the UHI. Here, it will thus be supposed that both types of panels are possible. Renew. Leloux, J., Narvarte, L., and Trebosc, D. (2012). 43, 2173–2178. The reference measurement is repeated at the end of the process. The above mentioned issues require further investigation in the perspective of an economic evaluation taking both positive and negative externalities into account. This means that it is not influenced by sea breezes, and hence that its UHI is stronger than for a coastal city of the same size. We can estimate the reductions in carbon emissions by using solar panels thanks to the IRENA calculator. It is also assumed to go back to the sky (we neglect the effect of the inclination of the solar panel on the direction of the reflected light). 33, 210–227. In order to study the impact of solar panels implementations on the urban atmosphere and on the population and buildings, we need an approach that looks at both spatial scales: buildings and city. Solar Thermal Technology Another way to tap solar energy is by collecting the sun's heat. Int. So if Nfloor is the number of floors of the building (variable calculated in TEB), the proportions of thermal panels (fther panel) and PV panels (fphot panel) are calculated as: The total production of the solar panels on the roofs can then be written: This is this quantity that is involved in the energy balance of the panel (section 2.2). doi: 10.5194/gmd-6-1941-2013, DeMunck, C. S., Pigeon, G., Masson, V., Meunier, F., Bousquet, P., Tréméac, B., et al. Fossil fuels coal, petroleum, and natural gas are our main sources of energy, producing the vast majority of fuel, electricity, and heat used by people across the globe. doi: 10.1016/j.rser.2013.05.057, Garg, H. P. (1974). Therefore, in the present study Effther was set to 0.60. Global average diurnal temperature range has decreased. Traisnel, J. P., Maizia, M., and Roditi, D. (2004). As mentioned above, we only consider the projection of the panels onto the horizontal surface (it would be absurd to make accurate calculations taking the inclination of the panels into account—except as noted above for production—when it is already assumed in TEB that all roofs are flat). It displays the number of hours per day that a person spends in this or any stronger level of stress. Sust. Photovoltaics and renewable energies in Europe. Right: without solar panels. doi: 10.1016/S0301-4215(02)00192-1, Sovacool, B. K., and Ratan, P. L. (2012). Energy. Futures 32, 261–2747. Sust. In summer, however, the solar panels reduce the energy needed for air-conditioning (by 12%), thanks to the shading of the roof. From our measurements, the value of 0.11 is used for αpanel in the present paper. “Eau chaude solaire - manuel pour la conception, le dimensionnement et la réalisation des installations collectives,” in Technical Report, Agence de l'Environnement et de la Maîtrise de l'Energie in French, 110. The instantaneous production is defined as Ether prod = Effther × Irr (W/m2 of solar panel) where Effther is the efficiency coefficient of the thermal panel and Irr the irradiance received by the panel. Rev. Global warming is characterized by cataclysmic potential, thus portending its harmful impact on the climate, environment (including animals and plants), and human health . You can either construct your own solar panels or call expert people to install the same at the roof of your house. Rev. 16, 1369–1376. Copyright © 2014 Masson, Bonhomme, Salagnac, Briottet and Lemonsu. The amount of solar energy that Earth receives has followed the Sun’s natural 11-year cycle of small ups and downs with no net increase since the 1950s. But global warming, caused by human activities like burning fossil fuels, farming and deforestation, is causing immediate and direct changes to the Earth's climate. This is reasonable, in particular for flat roofs with inclined panels, because the shadows cast by the panels can modify the radiative contribution to the roof beside as well as below the panels. Int. doi: 10.1016/j.enbuild.2013.10.038, Porfiriev, B. The present paper presents a way to implement solar panels in the Town Energy Balance scheme, taking account of the energy production (for thermal and photovoltaic panels), the impact on the building below and feedback toward the urban micro-climate through radiative and convective fluxes. Renew. Energ. Generally speaking, here are some examples of mitigation strategies we can use to slow or stop the human-caused global warming : Where possible, we can switch to renewable sources of energy (such as solar and wind energy) to power our homes and buildings, thus … Furthermore, solar power is also one of the few renewable energy sources that can be implemented on a large scale within cities themselves. Furthermore, it is considered that this per capita energy requirement can be satisfied by 1 m2 of thermal panel. When the SARS coronavirus was threatening back in 2010, researchers in North Carolina investigated temperature and coronavirus survival. 3. To evaluate their influence on urban weather, it is necessary to parameterize their effects within the surface schemes that are coupled to atmospheric models. Such a counter-intuitive phenomenon was found by DeMunck et al. Energ. For single story accommodation, 1/30 of the roof is then equipped with thermal panels, and (fpanel − 1/30) by PV panels. 2:14. doi: 10.3389/fenvs.2014.00014. Therefore, the impact of solar panels on historical or industrial buildings is probably counterbalanced by the other parts of the urban area, where solar panels will probably reduce the amount of solar radiation absorbed by the buildings (due to the reflection and conversion into energy by the solar panels). It typically varies from 11 to 16% depending on the position of the sun and the sensor inclination. The French Center for Aerospace Research (ONERA) laboratory maintains a current database of optical properties of urban materials. Effect of dirt on transparent covers in flat-plate solar energy collectors. It is diffuse and is also used as forcing data for TEB. 6, 929–960. This means that it is not influenced by sea breezes, and hence that its UHI is stronger than for a coastal city of the same size. This second, simpler approach is chosen here, and the coefficient of the French thermal Regulations of 2005 is used: The correction factor FT is typically 1.11 on annual average for a South facing panel in Paris. Net radiative forcing from widespread deployment of photovoltaics. Renewable energy strategies for sustainable development. Reuters. A recent working paper from a group of German researchers at the thinktank Institute for Economic Research (ifo) found that “electric vehicles will barely help cut CO2 emissions in Germany over the coming years”. During the month of August, in the first half of which the famous 2003 heat wave occurred, the impacts of solar panels on air temperature would be larger. There is no path to protecting the climate without dramatically changing how we produce and use electricity: nearly 40% of US CO 2 pollution comes from power plants burning fossil fuels. The … To establish the energy balance of the equivalent urban canyon, the TEB model needs the albedo (integrated between 0.4 and 2.5 μm) and the emissivity in the thermal infrared (integrated between 5 and 12 μm) for the following main areas: road, roofs, facades, glazing. Daytime temperatures have not risen as fast as nighttime temperatures. On the other hand, if the average number of spots rises, the Sun could serve to warm our planet even more. In any discussion about climate change, renewable energy usually tops the list of changes the world can implement to stave off the worst effects of rising temperatures. Everything you want to know about batteries, and more! Renew. It can reduce the usage of electricity and can reduce global warming from increasing Installing PV panels or thermal solar collectors on roofs of existing buildings will change the visual appearance of the urban areas concerned. Eight of the top 10 warmest years on record have occurred since 1998. The comparison between the two simulations indicates that the air-conditioning energy demand decreases by 12%. Solar energy is a non-renewable source of energy. Rev. Integrating rooftop solar into a multi-source energy planning optimization model. The focus is to keep the maximum of key processes, while making some approximations in the geometry that are pertinent at block scale (building shapes are averaged into road canyons, only one thermal zone is kept in the buildings, individual windows are averaged into a glazing fraction, etc.). Environ. Occup. An article published this month by our parent publication, Knowledge@Wharton, explores today’s market for … Modeling impacts of roof reflectivity, integrated photovoltaic panels and green roof systems on sensible heat flux into the urban environment. The SURFEXv7.2 land and ocean surface platform for coupled or offline simulation of earth surface variables and fluxes. In addition to these theoretical results, some practical issues have to be taken into consideration in order to better inform decision makers. Climate change is happening, despite the verbiage and rhetoric of the deniers. As the study reveals, probably not. Note that we take the inclination of the panel into account to calculate the irradiance for power production. The emissivity was measured using a SOC 400T apparatus (Figure 2, right). Development and evaluation of a building energy model integrated in the TEB scheme. Therefore, once the necessary area of thermal solar panels is reached, the remaining space allocated for solar panels on the roof will be devoted to PV panels. J. Appl. Furthermore, as mentioned above, 1 m2 of thermal panel is needed per capita. Health 80, 16–24. (2014). Sci., 04 June 2014 doi: 10.1016/j.energy.2006.10.017, Masson, V. (2000). While energy production and consumption patterns are changing fast, the shift to renewable sources needs to happen faster to reduce emissions and mitigate the effects of climate change. Some parameters needed by TEB, such as albedos, thermal characteristics or equipment within buildings, are deduced for each 1-km-by-1-km grid mesh from urban block types and from the use and age of the majority of buildings. Manag. Evolution of the Parisian urban climate under a global changing climate. 25, 749–758. Solar energy is a non-renewable source of energy. A recent New York Times column seems to imply that renewable energy investments set back efforts to address climate changenothing could be further from the truth. Hypotheses similar to those presented as “reasonably high deployment” in Taha (2013) are taken. Solar Energ. In summer, however, the solar panels reduce the energy needed for air-conditioning (by 12%) and also the Urban Heat Island (UHI): 0.2 K by day and up to 0.3 K at night. On the other hand, Taha (2013) studies the impact of solar panels on the whole urban area of Los Angeles. © 2018 UPS Battery Center Ltd. All Rights Reserved. Energ. ^http://www.insee.fr/fr/themes/document.asp?ref_id=ip1396. This approach estimates the impact on the UHI, but does not take account of the interactions with the urban canopy below (solar panel shadowing may lead to less cooling energy being used in buildings for example, leading to less waste heat outside). The snow mantel, if any, accumulates uniformly on the roof. Unfortunately fossil fuels are also the primary culprit behind climate change. The chosen year of study is 2003, because it demonstrates the impact the solar panels would have during a heat wave. The efficiency of these panels was assumed to be relatively high (20%), larger than the value used in the present study, but much smaller than the efficiency of thermal solar panels (60%). Le Bras, J. This mimics the fact that the water is heated during the day and stored until it is used during the next 24 h. So, using the regulation information above, the target energy production for 1 day can be defined as: The 12 factor has disappeared here because we consider ideal heating (i.e., sunny) conditions for the definition of the target. Global warming is caused by too many ‘greenhouse gases’ in our atmosphere – aka, gases that trap heat and warm our planet. However, Hernandez et al. Awareness to the people should be provided so that they can think of using solar panels to conserve energy. (2006). Thereafter, the reflectance of the solar panel placed in the center of the goniometer is acquired for all recorded positions of the detector and the light source. Calculation of air temperatures above the urban canopy layer from measurements at a rural operational weather station. You can use solar energy or solar panels to derive energy from the sun which is easily available and does not produce any harmful effects to the environment. Review of the performance of residential PV systems in France. The main hypotheses are: • On residential buildings and houses, the priority is given to thermal solar panels, which are more efficient. Then, massive installation of solar panels may even be beneficial for energy consumption. This gives: Eprod  is the energy produced by the panel. Sci. This can explain why a large portion of the metropolitan area of Los Angeles is impacted by the solar panels in these simulations. Environmental impacts of utility-scale solar energy. Average global temperatures show a similar trend, and all of the to… (2014), based on a simplified Urban Boundary Layer generator (Bueno et al., 2013; Le Bras, 2014) is chosen, in order to be able to perform a simulation over an entire year. At such a resolution, only the main characteristics of the buildings within the blocks in the grid mesh are kept. This captures at least the first order of an effect of the solar panel on the roof. This allowed realistic scenarios to be simulated, where thermal panels are introduced first. Rev. Solar radiation management is an idea that can reduce some of the risks of global warming by blocking out a small amount of sunlight. With future improvements in insulation, this impact will probably be less significant. Image Source http://www.ourhomemadelife.com. Geosci. Solar panels, probably by their effect of temperature, decrease the level on thermal stress of the population. Unlike work previously reported in the literature, the present study implemented both thermal and PV solar panels in the model. This increased cooling at night is due to a combination of several urban micro-climate processes. However, in doing so, they modify the energy balance of the urban surface in contact with the atmosphere, and so possibly influence the urban micro-climate. Impact of Solar Panels on Paris Urban Heat Island, http://www.insee.fr/fr/themes/document.asp?ref_id=ip1396, http://www.iea.org/publications/freepublications/publication/Solar_Thermal.pdf, Creative Commons Attribution License (CC BY). Sust. Solar geoengineering should not replace reducing emissions (mitigation), coping with a changing climate (adaptation), or carbon dioxide removal and sequestration. How to stop global warming? … But we can turn things around. Sci. Global warming has become a threat for living beings. Because the energy consumption for air-conditioning is low compared to that for domestic heating, the balance between the loss in energy in winter and the gain in summer induces an increase of total energy consumption by buildings of 1%. It depends of the nature (thermal or photovoltaic) and characteristics of the panel, the irradiance on the panel, the inclination of the panel (not taken into account in the other terms), and the air temperature. GHGs trap and add extra heat to the global system in ways that is changing the climate. Left: with solar panels. As of 2011, the technology produced less than one tenth of one percent of global energy demand. Figure 4. As a responsible citizen it is the duty of every human being to contribute for the prevention of global warming. Clim. But it also means that local adaptation strategies aiming at decreasing the UHI will have more potent effects. Here, we aim to evaluate the environmental impacts on the local climate, of implementing such a strategy at city scale. The methodology presented in Masson et al. This is an open-access article distributed under the terms of the Creative Commons Attribution License (CC BY). doi: 10.1016/j.solener.2010.12.023, Scherba, A., Sailor, D. J., Rosenstiel, T. N., and Wamser, C. C. (2011). Global warming is likely to be the greatest threat of the 21st century. Conceptualizing the acceptance of wind and solar electricity. doi: 10.1016/j.enpol.2013.10.048, Philibert, C. (2006). Future work will focus on studying urban adaptation strategies in the long term (as far as the end of the twenty-first century) taking a large panel of possible planning options into consideration, such as city greening, improved insulation, changes in occupants' behavior, different forms of urban expansion and the deployment of renewable energy systems. This is, of course, a scenario-dependent element, in the sense that it can be modified for each study. Difference of minimum or maximum air temperature between simulations with and without solar panels. LW↑panel is the long-wave radiation emitted (and reflected) by the solar panel to the sky. The greenroof module (v7.3) for modelling green roof hydrological and energetic performances within TEB. It is very easy to install solar panels. In the United States, theyre to blame for more than 80 percent of greenhouse gas emissions an… “Fast urban heat island model for thermal comfort studies,” in 11th Symposium on the Urban Environment (Atlanta, CA: American Meteorological Society). It is shown that solar panels, by shading of the roof, slightly increase the need for domestic heating (3%). It would be an improvement to be considered in the future. LW↓sky  is the incoming Long-Wave radiation from the atmosphere. Energy 32, 912–919. The deployment of solar panels in the Paris metropolitan area would not be neutral in terms of urban climate. (2013b) for air-conditioning, which was shown to have more impact at night than in the day (although the heat release itself was, of course, larger in daytime). These urban data are provided by a database at 250 m resolution (Figure 3 of Masson et al., 2014), which contains block types as well as 60 urban indicators. Inclusion of vegetation in the town energy balance model for modeling urban green areas. The present paper presents a way to include solar panels in the TEB scheme. How much air conditioning can increase air temperatures for a city like Paris (France)? The main impact of cities on the local weather is the Urban Heat Island (UHI). 1. Solar panels modify the nature of the rooftop and may thus influence the energy transfers to the atmosphere and the resulting UHI. 16, 5268–5279. This slight improvement in exposure to heat stress, although unplanned (solar panels are primarily implemented for energy production), can add to larger ones, specifically aimed at urban climate cooling, such as greening of the city. • On other types of buildings (offices, commercial, industrial, etc…) only PV panels will be installed. If the building has two stories, thermal panels will occupy 2/30 of the roof area, and so on. They found…. Clim. The city and urban heat islands: a review of strategies to mitigate adverse effects. doi: 10.1023/A:1002463829265, Masson, V., Champeaux, J.-L., Chauvin, F., Meriguet, C., and Lacaze, R. (2003). If long-term cycles in solar radiation reverse course and the Sun’s spots and faculae begin to disappear over the next century, then the Sun could partially counter global warming. On average, approximately 15 min of comfort is gained for outdoor conditions. They also “uncover best practices in wind and solar design and deployment that can better inform climate change mitigation efforts in the electricity sector.” Elliott (2000) underlines that renewable energy deployment requires a new paradigm, of decentralized energy production and small production systems. Except for the most recent industrial buildings (built after 1975), for which roof albedo is 0.5 and which, again do not cover a significant part of the metropolitan area, roof albedo for most buildings is estimated as 0.2 (e.g., tiles for houses and old industrial buildings or gray concrete roofs for collective buildings). 29, 105–122. Energ. This comes both from the fact that their deployment is favored for domestic buildings and from their much higher efficiency (the former being linked to the latter). Adapting cities to climate change: a systemic modelling approach. Figure 1. This means 1 m2 of panel per 30 m2 of floor area. Everyone is aware about the damage produced by global warming. Note that snow might change the energy produced by the solar panel (but this is not taken into account yet). The measurements for large samples of materials, e.g., for solar panels, were made using a goniometer (Figure 2, left). The production of the thermal panel is then computed in three steps: 1. The TEB scheme is able to simulate the energy, water and momentum exchanges between cities and the atmosphere at a resolution as high as the urban block (say down to 100 m by 100 m). Solar geoengineering does … The temperature dependent coefficient can be written as: Finally, the production of the PV panels is parameterized, also using the relationship between panel temperature and irradiance, as: The amount of energy produced by solar thermal panels is usually defined on an annual basis (Philibert, 2006). Very few parameterizations taking these exchanges into account exist in the literature. Large solar installations affect global and regional climate by taking solar radiation and distributing it in a different manner than natural processes. Renewable energy is one of the most effective tools we have in the fight against climate change, and there is every reason to believe it will succeed. Bound. Over the same period, global temperature has risen markedly. When the efficiency of PV panels is improved (up to 30%), Taha (2013) predicts that the cooling will reach 0.15 K. There are two possible explanations for the fact that more intense cooling is simulated for Paris. For example, while 17% of the total population is affected by heat stress for more than half a day (12 h) in the present city, the implementation of solar panels would reduce this number to 13%. (2011), who modified the Energy+ software (software dedicated to building energetics) to improve its previous solar panel model (which only computed the energy production). This work has received support from the French National Research Agency for the MUSCADE project (reference ANR-09-VILL-0003) and from the thematic advanced research network on Aeronautics and Space for the ACCLIMAT project (RTRA STAE—ACCLIMAT).
