The Smart City Wien Framework Strategy (SCWFS) provides an inclusive vision for the long-term sustainable development of the city. Considering the sustainable energy development, SCWFS focuses on energy efficiency improvement, increasing the local generation of renewables and ensuring an ambitious GHG mitigation path.

Using the optimisation framework MESSAGE, an optimal energy supply strategy up to 2050 has been formulated.

The sustainable development scenario (SDS) shows a switch to clean fuel and increased electrification, resulting in a decrease in primary energy (PE) demand at an average annual rate of 0.9% from 41.7 TWh in 2016 to 30.3 TWh in 2050 corresponding to a total PE saving of 40% compared to the BAU scenario.

The SDS results will achieve the set targets of SCWFS reflected in decreasing the final energy (FE) consumption per capita to 48% by 2050 compared to 2005, increasing the share of renewables in FE consumption to 73% by 2050, and doubling the share of renewable energy production within the city boundary by 2030 compare to 2005. The result of 1.86 tCO₂/cap by 2030 is close to the set target of 1.76 tCO₂/cap, whereas the 1.16 tCO₂/cap fails to reach the set target of 0.53 tCO₂/cap by 2050.

智慧城市维恩框架战略 (SCWFS) 为城市的长期可持续发展提供了包容性愿景。考虑到可持续能源发展，SCWFS 专注于提高能源效率、增加当地可再生能源的发电量并确保采取雄心勃勃的温室气体减排路径。

使用优化框架MESSAGE，制定了到2050年的最佳能源供应战略。

可持续发展情景 (SDS) 显示转向清洁燃料和增加电气化，导致一次能源 (PE) 需求年均下降 0.9%，从 2016 年的 41.7 TWh 下降到 2050 年的 30.3 TWh，相当于总与 BAU 方案相比，PE 节省 40%。

SDS 结果将实现 SCWFS 的既定目标，即到 2050 年将人均最终能源 (FE) 消费量比 2005 年降低至 48%，到 2050 年将可再生能源在 FE 消费量中的份额提高至 73%，并使人均最终能源 (FE) 消费量增加一倍。到 2030 年城市边界内的可再生能源产量与 2005 年相比。 到 2030 年 1.86 tCO ₂ /cap的结果接近设定的 1.76 tCO ₂ /cap目标，而 1.16 tCO ₂ /cap 未能达到设定的目标到 2050 年为0.53 吨CO ₂ /上限。
