Title Solar electricity production and taxi electrical vehicle conversion in Chile Type
Year 2019 Publication Journal Of Cleaner Production Abbreviated Journal J. Clean Prod.
Volume 210 Issue Pages 1261-1269
Keywords Electric vehicle; Public transport; CO2 emissions; Solar charging station; Chile
Abstract Carbon emissions from the Chilean public transport sector have doubled between 2000 and 2013. Thus, the need to find alternative clean-air solutions is becoming increasingly critical. With this in mind, this paper addresses a solution to the aforementioned problem by studying the conversion of both taxis and “colectivos” (public taxis with defined routes) into electric vehicles (EV) to be used in the Chilean public transport sector. In Chile, 80% of taxis are Nissan V16s, meaning that all of these vehicles will be replaced and end up in landfills within the next 5-8 years. This study presents an option to give a second life to these vehicles, addressing environmental and financial issues. It compares emissions from the Nissan V16's conventional internal combustion engine (ICE) with an equivalent electric conversion prototype. Furthermore, it analyses the CO2 emissions from the EV that has been fully charged by the Chilean grid as well as one that has been charged by a solar photovoltaic system. A solar recharging station for EV taxis is designed, taking advantage of the high levels of solar radiation in Chile. The results show that EV conversion does not lead to real environmental benefits, in comparison to its ICE equivalent, when it is charged with the grid. However, the results also show a considerable decrease in cost and CO2 emissions per km travelled when using solar energy to charge the batteries. Future challenges include identifying solutions to cope with solar intermittence and minimizing CO2 emissions during periods of low radiation. (C) 2018 Elsevier Ltd. All rights reserved.

Title Renewable energy expansion in the Chilean power market: A dynamic general equilibrium modeling approach to determine CO2 emission baselines Type
Year 2020 Publication Journal Of Cleaner Production Abbreviated Journal J. Clean Prod.
Volume 247 Issue Pages 11 pp
Keywords CGE model; Renewable energy; CO2 emissions; Chile
Abstract Over the last decade, a high dependency on carbon-intensive fuels in the Chilean power sector has led to environmental concerns, particularly regarding rapid growth in CO2 emissions. More recently, the power sector has experienced significant structural changes with a rapid expansion of renewables in the energy matrix, and this trend is expected to cause significant variations in future CO2-emission baseline scenarios. To investigate the economy-wide impact of renewable energy expansions in Chile's energy mix, this research, based on a Computable General Equilibrium (CGE) model, examines different CO2 emission baseline scenarios. However, because traditional CGE modeling approaches cannot capture the impact of a sector's recent structural changes, we present a step-by-step approach to incorporate different energy matrices from an external engineering bottom-up model into the CGE model. The results indicate that the Business as Usual (BAU) scenario, in which structural changes are not considered, significantly overstates expected emissions. Conversely, considering structural changes in our CGE model shows Chile advancing towards its declared Nationally Determined Contribution (NDC) to reduce greenhouse gas emissions. Furthermore, the methodology implemented in the study has the advantage of being a simple integrated approach that is coherent with current modeling capacities in many developing contexts.

Title Modelling energy use in residential buildings: How design decisions influence final energy performance in various Chilean climates Type
Year 2019 Publication Indoor And Built Environment Abbreviated Journal Indoor Built Environ.
Volume 28 Issue 4 Pages 533-551
Keywords Energy modelling; Building thermal performance; Parametric sensitivity analysis; Energy efficiency; CO2 emissions; Chile
Abstract To reduce the energy consumption in buildings, there is a demand for tools that identify significant parameters of energy performance. The work presents the development and validation of a simulation model, called MEEDI, and graphical figures for the parametric sensitivity investigation of energy performance in different climates in Chile. The MEEDI is based on the ISO 13790 monthly calculation method of building energy use with two improved procedures for the calculation of the heat transfer through the floor and the solar heat gains. The graphical figures illustrate the effects of climate conditions, envelope components and window size and orientation on the energy consumption. The MEEDI program can contribute to find the best solution to increase energy efficiency in residential buildings. It can be adapted for various parameters, making it useful for future projects. The economic viability of specific measures for building envelope materials was analysed. Payback periods range from 5 to 27 years depending on the location and energy scenario. The study illustrates how building design decisions can have a significant impact on final energy performance. With simple envelope components modification, valuable energy gains and carbon emission reductions can be achieved in a cost-effective manner in Chile.
