The director of the Research Institute for Sustainable Housing Minnesota is visiting Montevideo and Maldonado. Approached by the founding Partners of the Americas, will exhibit at the National Conference of Architects on new technologies for sustainable architecture, yet accessible to disadvantaged sectors, two concepts which, he says, are complementary. SEBASTIAN

AUYANET - What are the main challenges when developing sustainable architecture projects as needs go home by the absence of any type to be?

"For starters, assume that the context in which such projects are given varies everywhere, of course not the same in Minnesota in Montevideo. However, both variables can and must be supplemented. Housing solutions must accompany the energy savings, which ultimately becomes a savings for the government. When looking for low-impact material, in fact this should be low impact and energy costs. Water conservation or concerns about the health of the people who occupy something that housing plays a key role, are some of these challenges. You can create affordable housing and sustainable.
- What are the main aspects of what is known as affordable housing?
"First, maximizing space, building homes that are as small as possible. Of course this is always taking into account the number of members of each house. There are changes that are actually very simple and easy to implement, for example, provide this type of houses in a thick insulation, which allows less interference from weather. We must also make a special development in the pipes of the houses, to develop to retain water better, that already exist and are widespread. Another aspect that is paying much attention to the efficiency of windows in relation to the entry of light and their ability to tune or cool the house. In fact, they are simple changes in their great majority. "It is clear that this contribution is key. It is currently difficult, but the demand for cheaper materials should lower prices and make positive cycle. Another option is prefabricated more to prevent errors. Sometimes in a plant are monitored and standardized things to build on the same site are not achieved as well. There are multiple strategies that may apply. The role of architects in this is also very important, as they know that sustainable architecture does not require going against the architectural styles, much less against the design.

- And what form should operate the government?

"Of course the most powerful weapon is to change the laws and regulations to encourage these types of buildings. If the government is working to reduce its own energy consumption, say, 30% or 50%, people start to take these things more seriously. That is one of the messages that occur. To impose energies like solar or wind, you have to press with such policies.

- Is the perspective of people who are going to build a house will also change?

-key thing here are the signs. One of the things that the more I wonder since I got here is why in a country with good potential for wood construction, no more houses of this type. Material is more profitable than cement and concrete. In the U.S., this is something assumed and normal, is the material most commonly constructed. Here, we must find arguments to justify that encourage people to build with these materials. Can be more durable, safe, efficient, are built quickly and in turn, can be aesthetically beautiful. I think that has to do with starting to consider it as an alternative.

- Where do you begin to generate this kind of cultural change?

"First of all, training architects in this type of architectures. Of them also depend on the acceptance to rise. They will also have lower costs. I think one of the most influential may be to create a neighborhood of this type with a housing cooperative, and people see how it works. Montevideo primary objective should be to come to a building "zero energy". I think most changes arising out of necessity. We continue to build in this way, waiting for a climate crisis and react, or start with new ideas to prevent interesting.

Climate change is often more accountable to the major producers to small consumers. How significant the contribution from the houses built?

"I have no fees or relationships here, but in the U.S., 40% of energy consumption has to do with buildings that consume the most inefficient way. 30% is used in transportation, and other industries. It is a very large percentage, and closely linked to the materials used there as gases, and the impact they have. And we're not talking about building buildings again, but to implement a number of key improvements that the operation has a more efficient consumption. Finding new ways to build is one of the alternatives. The other is to adapt the old buildings. This is more urgent than we think, it is said that in ten years things can get complicated even more, and what is needed is a dramatic change in how we think this type of construction.
