My university has green infrastructure to reduce energy consumption. There are two trigeneration plants. They have two gas engines: 1.2 MW and 400 kW, absorption chiller, ... Heating, cooling and electricity generation is provided from these plants.
Also, 1 MW solar power plant is planned and a study on the disposal of solid wastes was started. However, there is no publication about these facilities.
You also might consider expanding your search terminology to include Urban Forestry. The term "Green Infrastructure" was originally coined by the US Environmental Protection Agency back in the day when that was actually their concern. The term was used to describe green infrastructure created to reduce storm water runoff as well as increase infiltration rates such as rain gardens or permeable paving. If you expand the search, you might get better results in how trees, unsealed soil, etc reduce energy consumption since urban forestry addresses the entirety of the ecosystem rather than just what has been constructed.
Be careful not to conflate 'green' energy provision infrastructure with 'green infrastructure' which has developed into a nature-based concept in many parts of the world over the last couple of decades.
