Abstract

Energy is an important issue in the entire world and in under-development countries especially in these regions is where the main growth of energy requirements is expected. For more than fifty years ago Ecuador has been subsidizing fuels, considering that energy prices do have a huge impact on lowincome families. Cities and buildings do play a relevant role in reducing energy requirements to import energy to urban areas in order to achieve the maximum energy self-supply capability in buildings and cities. This study describes shortly recent works performed in Cuenca to decipher the energy resources available and the capability to self-supply in Cuenca, Ecuador. The main results obtained show that photovoltaics (PV) in buildings is the best option, it could supply the entire power requirements in the city, and around 22 % of the electrical requirements of industrial high-consumption buildings, also for a single-family home it is only required around 7 m2 of roof that corresponds around 10 % of a typical roof availability of a typical 2-floor house, and for higher education building it is possible to achieve the total power requirement with PV technology, but grid limitations imply limitations also to PV capability.
光伏评估,以实现能源中性的建筑和城市在赤道安第斯气候
能源是整个世界的一个重要问题,在不发达国家,特别是在这些区域,能源需求预计将主要增长。考虑到能源价格确实对低收入家庭有巨大影响,厄瓜多尔50多年前一直在补贴燃料。城市和建筑物在减少能源需求方面发挥着相关作用,向城市地区进口能源,以实现建筑物和城市的最大能源自给能力。本研究简要描述了最近在昆卡进行的工作,以破译厄瓜多尔昆卡的可用能源和自我供应能力。获得的主要结果表明,光伏(PV)在建筑物中是最好的选择,它可以满足城市的全部电力需求,大约22%的工业高消费建筑的电力需求,对于一个单户家庭来说,它只需要大约7平方米的屋顶,相当于典型2层房屋典型屋顶可用性的10%左右。对于高等教育建筑来说,光伏技术可以满足总电力需求,但电网的限制也意味着光伏发电能力的限制。
