"Net positive buildings are also coming on like gangbusters and there is a German village that produces five times the energy it needs through renewables. Please note that this article about it is from 2013 and the state of the art has moved on since then. http://www.yaleclimateconnections.org/2013/07/with-citizen-buy-in-german-village-generates-5x-renewable-energy-it-needs/

Another example are these net positive townhouses in the Roxbury neighborhood of Boston http://www.is-architects.com/roxbury-e

Net zero energy is not just for new buildings as well. A retrofit home in Whatcom County, Washington produces twice the energy it now consumes. In this area, the solar insolation is 3.5 - 3.0 kWh/square meter/day. Germany, with that 500% net positive village, has an average solar insolation (or irradiance) of 2.9 kWh/square meter/day. http://inhabitat.com/retrofitted-net-zero-home-in-washington-produces-double-the-energy-it-needs/

It’s not just one-at-a-time as construction companies like Sekisui Heim of Japan builds "zero-utility cost" houses and has constructed over 160,000 units with "solar generation systems" http://www.sekisuichemical.com/about/division/housing/

Buildings can achieve net zero almost anywhere in the world. Here’s information on the Northernmost net positive energy office building (so far): http://snohetta.com/projects/283-powerhouse-telemark http://inhabitat.com/worlds-northernmost-plus-energy-office-could-spark-an-energy-revolution/

The Southernmost is the Princess Elisabeth Station in Antarctica http://www.antarcticstation.org

From pole to pole, in most building types, as eco-districts and net zero cities, Net Zero Energy Vermont focuses on making Vermont the first zero energy state http://www.netzeroenergyvt.net/ Net zero energy feasibility study for Vermont buildings (and beyond) https://www.efficiencyvermont.com/news-blog/whitepapers/net-zero-energy-feasibility-study

I also collect links on City Agriculture (archived at http://cityag.blogspot.com) and have found that urban agriculture and net zero energy buildings are merging. Daniel Libeskind, the “starchitect,” has designed both net zero energy buildings http://libeskind.com/search/Ogden+Center http://inhabitat.com/daniel-libeskind-unveils-spectacularly-green-physics-center-at-durham-university/ and vertical gardens http://libeskind.com/search/Toulouse https://www.dezeen.com/2017/03/27/studio-libeskind-150-metre-high-occitanie-garden-tower-toulouse-business-district-architecture/

This synergetic trend is only going to continue and speed up, expanding to include buildings that not only produce as much energy as they consume or more while feeding the local population and even improving the air.
