为了支持应对气候变化的国家和国际政策，欧洲和亚洲各地的地方政府都致力于减少温室气体排放。许多人认识到，分散的可再生电力生产可以在减少排放的同时产生收入。然而，这些参与者经常受到巨大的财务压力，这意味着需要一个可靠和引人注目的商业案例来证明前期投资的合理性。本文利用风能和太阳能资源预测技术的数据，开发了一种快速比较多个城市地点和安装方案的初始项目可行性的方法。在这样做的过程中，以学术研究为基础的详细资源评估可以为城市实践者提供和使用。利用对数垂直风廓线预测长期平均风速。该方法采用详细的三维建筑数据来估计复杂城市地表的空气动力学参数。利用基于地理信息系统的方法对太阳能资源进行建模。这建立了屋顶结构的位置和几何形状，以估计日照，同时考虑其他建筑物和地形特征的遮阳效果。潜在装置的项目可行性是根据技术生命周期内的净现值和相关的上网电价激励来评估的。还计算了所有站点的贴现投资回报率。该方法在英国利兹市议会拥有的6794个地点的案例研究中得到了验证。研究结果表明，跨议会资产的小规模风能和太阳能发电潜力巨大。许多站点提供了有说服力的商业投资案例，并且在所有情况下，使用现场产生的电力可以提高财务可行性。这表明初始装置应设在电力需求高的资产上。总的来说，这项工作建立了一种方法，使大型城市级资产持有人能够在整个投资组合中做出战略投资决策，这些决策基于对风能和太阳能发电潜力的财务评估，准确到单个资产规模。这些工具可以促进城市内部的战略规划，并有助于确保对可再生能源的投资集中在最可行的地点。此外，该方法可以协助城市规模的资产管理，因为它可以确定市场价值较高的场址，因为这些场址具有可再生能源发电的潜力，而不是以其他方式估计的。(C) 2015年作者。Elsevier Ltd.出版。这是一篇基于CC BY许可（http://creativecommons.org/licenses/by/4.0/）的开放获取文章。
In support of national and international policies to address climate change, local government actors across Europe and Asia are committed to reducing greenhouse gas emissions. Many recognise the contribution that decentralised renewable electricity production can bring towards reducing emissions whilst also generating revenue. However, these actors are often subject to significant financial pressures, meaning a reliable and compelling business case is needed to justify upfront investment. This article develops a method for rapid comparison of initial project viability for multiple city sites and installation options using data from wind and solar resource prediction techniques. In doing so, detailed resource assessments grounded in academic research are made accessible and useful for city practitioners.Long term average wind speeds are predicted using a logarithmic vertical wind profile. This employs detailed three-dimensional building data to estimate aerodynamic parameters for the complex urban surface. Solar resource is modelled using a Geographical Information System-based methodology. This establishes the location and geometry of roof structures to estimate insolation, whilst accounting for shading effects from other buildings and terrain features. Project viability for potential installations is assessed in terms of the net present value over the lifespan of the technology and associated Feed-in Tariff incentive. Discounted return on investment is also calculated for all sites. The methodology is demonstrated for a case study of 6794 sites owned by Leeds City Council, UK Results suggest significant potential for small-scale wind and solar power generation across council assets. A number of sites present a persuasive business case for investment, and in all cases, using the generated electricity on site improves financial viability. This indicates that initial installations should be sited at assets with high electricity demands. Overall, the work establishes a methodology that enables large city-level asset holders to make strategic investment decisions across their entire portfolio, which are based on financial assessment of wind and solar generation potential accurate to the individual asset scale. Such tools could facilitate strategic planning within cities and help to ensure that investment in renewable energy is focused at the most viable sites. In addition, the methodology can assist with asset management at the city scale by identifying sites with a higher market value as a result of their potential for renewable energy generation than otherwise might be estimated.
