En el barrio de Valdespartera, en Zaragoza, todos los edificios se construyeron y se dispusieron teniendo en cuenta criterios medioambientales. Son viviendas tan bien preparadas, que según el arquitecto técnico Luis Miguel Soler, tendrían una "B" en la escala de calificación energética.

"con el cambio del gasoil a biomasa los vecinos de las 237 viviendas del edificio Grial, ubicado en el barrio de Las Batallas, ahorrarán más de 41.000 euros al año."

Desde junio de 2013, la empresa de gestión de residuos lanzó la campaña Limpinho 3R. El programa ofrece una tarjeta a los ciudadanos que les permite la acumulación de puntos y el intercambio de bienes y serviciosEl programa también hace un esfuerzo por involucrar a los catadores locales, los recolectores de residuos tradicionales que acumulan los residuos reciclables en la ciudad. Limpinho 3R fomenta exclusivamente las cadenas de valor locales, las cuales a la vez, generan un círculo virtuoso en el barrio. también desarrolló la aplicación "Olha Isso, Limpinho!" (Mira eso, Limpinho!) que permite a los ciudadanos denunciar directamente a la municipalidad los residuos no recogidos en la ciudad.

En Montevideo abren inscripciones para la refacción y mejora de las viviendas que se encuentran en la zona delimitada por: Ciudadela, Barrios Amorín y las paralelas entre Maldonado y Paysandú. Hasta el 26 de lulio de 2013

The project uses the frame of a 1950s building as a shell in which to build its experimental space. Over the past five years, this formerly vacant building has been repurposed and extended with minimal costs for materials. Professor Bernd Kniess, dean of Hafencity University's urban design department, is primarily concerned with questions of sustainability, renewal and repurposing in urban space. How to transform the existing? How can the new emerge from the old? Both the building itself and the city around it are employed as resources. Every piece of the building that is removed in the remodeling is then redeployed with a new function elsewhere. Discarded materials from surrounding construction sites are harvested and upcycled at the UdN. This patchwork process requires those engaged in the reconstruction to deal with building's structure as it was found, to develop new courses of action and productively channel uncertainty and risk. In this situation, sustainability does not rest solely on the objects used. Most importantly, it is fostered by relationships-by the neighborhood.

BeyWatch is a 30-month research project supported by the European Commission (DG Information Society and Media) aiming at ICT tools for environmental management and energy efficiency. BeyWatch will develop an energy-aware and user-centric solution, able to provide intelligent energy monitoring/control and power demand balancing at home/building & neighbourhood level.

Eco Village residents will have community produce gardens and common green spaces and walking trails. There are even plans for a small fleet of communal electric cars. Houses are designed to qualify for LEED-Platinum certification. Houses have their own photovoltaic arrays, between 5 kW and 6 kW in capacity, plus solar thermal systems designed to provide about half of the domestic hot water demand. A separate 75 kW PV installation at one end of the property will provide power for community purposes, such as lighting, and will also produce revenue that can go toward additional construction. The many energy enhancements should save a family between $200 and $300 per month in utility bills when compared to a conventional home of the same size and $100,000 over the course of the 30-year mortgage. Since the project was launched, there has been a 69% increase in the number of volunteer hours donated to the local Habitat chapter, and a 59% jump in the number of volunteers. In all, hundreds of volunteers donated 16,000 hours of time to get the first part of the project complete.
