(II) Solar energy house: the Solar Decathlon

16 July, 2010 No Comments

Evaluating the Solar Decathlon project, we see that:

  • It is a renewable energy system, where the consumer becomes its own electricity generator.
  • The sponsor Schneider Electric has created a microgrid or intelligent power system, which converts the 17 homes that were part of this project in a self-sufficient network, which could even sell electricity to utilities. Unlike conventional network, in which there is only one source of energy (electricity company) and all network elements are consumers, in microgrid, the consumer is able to generate electricity and could be connected elements at times acting as consumers or power generators.
  • Therefore, future homes, fed with any type of renewable energy, inject their excess energy network and, in turn, in the event that there is little solar radiation, would feed electricity from the system. It should also be able to store some of the energy in batteries to be used later on.
  • This system is currently used in isolated or not connected to the electrical grid areas, mainly due to the complexity of managing electric power, that’s why it is limited to hotels, public buildings, etc.
  • We have built 17 real houses, sustainable, self-sufficient, comfortable and fed exclusively by solar energy. Of the houses that have intervened, the winner was “Lumenhaus” held by the team of Virginia Tech University

From the above we can deduce that in the future, these systems will lower enough the power consumption of households, this may complicate the lives of the electricity companies, as they not only lose a part of the business, but produced in accordance with demand, because this demand will vary as they generate electricity which, until now they have only been consumers.

All these advantages should help promote the increased use of renewable and clean energy at the expense of current ones, whose use is more polluting and damaging to the ecosystem.

(I) Houses with renewable energy: Solar Decathlon project

15 July, 2010 No Comments

We will see that when houses are able to generate their own renewable or clean energy, do not spend more than necessary and reaching a responsible consumption reaches where each consumer becomes its own electricity generator.

Differentiating energies:

  1. Non-renewable energy. Are exhaustible, due to the reserves of fossil fuels and materials used to produce nuclear energy is limited (coal, oil and natural gas) which also cause large emissions of CO2 to the atmosphere, creating the current situation of climate change as well as her removal and extraction is complicated (causing disasters like the Prestige and the Chernobyl nuclear power plant).
  2. Renewable energy. They are inexhaustible and never ceased to occur. Renewable energies include wind power, solar thermal, solar photovoltaic, biofuels, geothermal, those from the sea, biomass and hydro.

What is the Solar Decathlon?

An International Architecture & Engineering Competition sponsored by U.S. Energy Department, along with the National Renewable Energy Laboratory, where the participating universities should build a house supplied entirely by solar energy.

It is noteworthy that the sun is at the basis of all renewable energies, the heat causes it to produce pressure differences that give rise to winds and organizes water cycles, leading to evaporation and therefore the rains, while promoting the plants perform photosynthesis.

The 17 houses participating in “solar village” has produced nearly three times the energy they have consumed. The excess energy has been poured into the network and used by residents of the area where the houses have been built.

A different architectural project

6 July, 2010 No Comments

This is the world’s largest “playing card development. The creator of this project, Bryan Berg, an American architect Harvard graduate, spent 44 days building it.

As the author, this is a very complex project because it needs to be designed like a real building, room by room, and taking into account what weight should support each point of support.
