Solar energy for urbanization. Stage 2
A second stage of the program “Thermal solar energy in social housing” is taking place at the moment. With the objective of supplying with hot water to the neighbors and reduce energy consumption, the project promotes the use of renewable energy, specifically solar thermal, and seeks to install the concept of energy rational use and energy efficiency among the neighbors. It takes place in the low income neighborhood: “Villa 1-11-14”, a well known shanty town of Buenos Aires City, for its size and population number (calculated in 40,000 habitants). In this case, the program has recently installed water heating solar collectors in two Community Center buildings, and has installed solar water heaters in the five selected residential houses. It is important to consider the awareness raising effects this program has; bearing in mind the community center is used by children, who happen to be great communicators for best practice techniques. In the same line, as neighbors do not usually pay for the electricity fee, improving consumption behavior raises as one of the priorities in these kinds of settlements; especially considering that the energy demand in Buenos Aires, in residential and service sector especially, has duplicated in the last 10 years. At the same time, we are currently developing the first program for socio-environmental initiatives in communities, which consists of the granting of nonrefundable contributions (subsidies) aiming at financing eco-friendly projects of production and infrastructure which help improve the standard of living of vulnerable communities. Currently, training courses on these technology and environmental awareness are offered by the Environmental Protection Agency. Start year 2011

Preferential bus lanes
Bus transportation in our City has a long history and was pioneer in Latin America. Around 9,700 buses move around the City and the Metropolitan Area. Around 80% of our city’s air pollution is estimated to come from vehicle gas emissions. That is why the City Government implemented a 10.7km network of exclusive lanes for bus and taxi circulation in order to reap the benefits of these forms of transportation while addressing the issues that have traditionally undercut their effectiveness. This change in circulation implies transforming one-way avenues into two-way ones, in order to increase passenger flow. An immediate result of this program has been journey time reduction. Preferential lanes for public transportation and counter- flow lanes do account for the reduction of 10% to 35% of journey time reduction. In the same line noise has been reduced, improving life quality in many arterial roads in the City. Start year 2009

The trees found at the side of the road are more than a mere example of the City’s natural landscape. They also help improve air quality, reduce noise, moderate high temperatures, capture particulate matter (smoke), reduce flood risks, provide shelter for wild species, and, of course, reduce greenhouse gas emissions. Buenos Aires is a city well known for its beautiful street trees. In order to maintain them, we have performed the first phytosanitary census, one of the most important inputs in order to make street trees maintenance part of a real State Policy. It provided with accurate knowledge regarding the diversity, specimen quantity, general state, distribution, and georeference of the different varieties. It is from this study that the City defined the basis of the Urban Trees Master Plan. This Plan have the objetive to achieve a total of 440,000 trees by engrossing and improving linear woodland.

Bus Rapid Transit - Stage 1
The Bus Rapid Transit system (BRT), or Metrobus as it is called in Buenos Aires, is used in more than 150 cities around the world. Because it uses an exclusive center lane, journey time is reduced around 40%. In avoiding constant moving and stopping, this means of transportation reduces emissions and fuel expenses and helps reach established schedule deadlines. The Metrobus is part of the Sustainable Mobility Plan, and aims to provide the city with a road infrastructure for a large number of passengers, with a high quality bus service according to traditional urban buses. We have chosen Juan B Justo Avenue to launch this system because it connects the City from West to East. Besides, it connects the passengers with one of the railroads and two subway lines. Each one of the 100,000 BRT passengers save 75 hours of journey time during one year. Juan B Justo BRT corridor is 12 km long and 7 bus lines run within it. Start year 2010

Solar Energy for Urbanization
Using solar energy for heating is a tool for social inclusion. During 2010, in the neighborhood “Los Piletones”, located in the southern area of the City, and with the support of the Embassy of the Federal Republic of Germany as well as other organizations, solar collectors have been installed as a first stage of a program aiming for “Thermal solar energy in social housing”. The solar collectors provide with hot water the Community Center and five residential homes. In shanty towns undergoing urbanization, water heating, when existent, is produced by means of electric heaters, which are usually precariously connected, thus, in many cases, entailing high risk. Solar collectors installed in this neighborhood allows for users to have hot water all year long, while at the same time reducing future energy costs. Hot water in the Community Center benefits at least 60 children. The massive incorporation of this technology may also limit construction of higher stories, a major concern given that construction in the area tends to be irregular and its ongoing development could result in higher structural risks.

Buenos Aires City Government inaugurated it´s first Green Roof in 2011 and, because it was constructed on a public school building, a low maintenance design was chosen and a path was built across the green area for student use. Moreover, the plants chosen are resistant to a wide temperature range. The green roof has been constructed over part of the rooftop, so that two sectors of equal size and orientation were left to compare hydraulic balance and thermal benefits to the school. A follow up took place, measuring temperature differences and water capacity. At the moment, more green roofs are being constructed in schools and other public buildings, under the Green Buenos Aires Plan. In the same line, the City has started the installation of green walls in urban highways. Start year 2010
