Solar Decathlon 2014 has reached the final stage and the Italian project RhOME for denCity gets off to a great start, earning 5 bonus points for completing the construction of the house within the 10-day time limit set by the competition!

I already told you a few months ago about the RhOME for denCity project created by the team ofUniversity of RomaTre, with the support of Daikin and the challenge Solar Decathlon 2014, an international competition dedicated to architecture schools from around the world and aimed at collecting eco-sustainable housing projects that use solar energy to meet most of their energy needs.

Over the past weekend I had the opportunity to go in person to the "Cité du Soleil" in Versailles, where the finalist teams built the houses of the individual projects in the area specifically used for Solar Decathlon 2014.

In the opening image above you can see how the house of the Italian team of the University of RomaTre looked like coordinated by architect Chiara Tonelli: our tricolor flag positioned on the entrance ramp is a must!

The house designed by the RhOME for DenCity team is designed for the ecological and social "redensification" of the Roman suburbs, powered 100% by solar energy and with low construction costs, especially in relation to the high quality standards in terms of quality of materials , available technology, size of living spaces and cost-effectiveness of energy consumption.

The prototype of the RhOME house was engineered and built in Chienes, in the province of Bolzano, from Rubner Group, a partner company of the project, specialized in the construction of wooden houses. It was then disassembled, transported by train and reassembled on the ground of the Solar Decathlon in Versailles.

But let's get to the details of the project that I was able to appreciate inside the house and that were presented to me by the team members:

1) Theheat pump provided by Daikin uses a refrigerant gas with a global warming potential that is 67% lower than traditional ones and 2.5% of the global turnover invested in research. At the heart of this commitment is the “3R + R” principle (Reduce, Reuse, Recycle + Repair) with the recent introduction of a single-component refrigerant that can be easily disposed of after having reached the end of its life cycle.

2) The energy and comfort parameters monitoring system by RhOME was made byAlmaviva, A leading Italian group in ICT, with a strong focus on eco-sustainability policies.

3) The RhOME kitchen, Mechanics of Demode engineered by Valcucine, is designed to be 80% reusable and 100% recyclable. The multilayer panels are made of natural fir, while the eco-sustainable Re-y-Stone laminate is made of natural resin acquired from sugar production waste, a resistant surface that combines functionality and design. The water-repellent chipboard cat. P3 has a low formaldehyde emission.

4) I. flexible photovoltaic solar panels, integrated in the shading screens of the loggias, are produced by Solbian and guarantee the energy production of the house.

5) The bathroom, prepared by IdealStandard, presents a series of ecofriendly mixers which thanks to their technological features reduce the water in the tap by 80%, while retaining the jet power. Furthermore, the water never comes into contact with heavy metals, passing only in high-performance technopolymer ducts and therefore being completely nickel and lead free.

6) The water, sanitary, electrical and air treatment systems are contained in the element 3D CORE connected to a server that receives and records data from all over the house.

7) the lodges positioned to the north and south have a dual function: to favorlighting with natural light for as many hours as possible during the day and optimize the natural ventilation creating a current that goes from the coolest (north) to the warmest (south) area.

8) Theartificial lighting is made withModular LED / OLED and after a lighting study to optimize visual well-being.

9) The windows are provided by Velux have the purpose ofminimize thermal dispersion increasing the energy efficiency of buildings and passive defense against heat and cold.

10) RhOME includes a centralized system for the disposal, reuse and recycling of rainwater and gray water.

RhOME it was designed and built respecting all anti-seismic criteria and produces more than it consumes: the house has energy performance almost 8 times higher than those of an energy class C and one and a half times higher than those of an energy class A +.

To say that we can be proud, as Italians, of this beautiful project and that the least we can do is rate it to try to get him to win the public jury prize, hoping that he can also win that of the expert jury of the Solar Decathlon 2014.

To appreciate all the photos of the RhOME project taken in Versailles, I highly recommend that you look at the dedicated photogallery.

I conclude this article with due tribute to RhOME team you see gathered in this photo!

    As a specialist, I can help. Together we can come to the right answer.

    Sorry, but this doesn't suit me. There are other options?

    I apologize, I wanted to express my opinion too.
