The CISOL- Solar Research Centre ETSAV promotes the sustainable solar projects at the Vallès School of Architecture of the (ETSAV).

•CISOL serves as a centre for information, exposition and documentation about solar technologies and renewable energies in buildings for students as well as architects. It offers information, consultancy and contacts to specialized companies.

Within regular and elective classes at the Vallès School of Architecture (ETSAV), CISOL introduces students into solar design, solar technologies, and energy efficiency in buildings, from bioclimatic concepts up to high tech architecture.

The CISOL Solar Workshops about integration of solar technologies and energy efficiency in buildings foster the development of high quality projects based on integrated energy design.

The LOW3 project (www.low3.upc.edu) for the SOLAR DECATHLON EUROPE 2010 competition introduced new concepts of participatory teaching and an experimental building site for the evaluation of prototypes into the Campus Sant Cugat.

• The Solar Cube - Solar Laboratory ETSAV has been developed by the CISOL (Solar Research Centre ETSAV) of the Universitat Politècnica of Catalonia under the direction of the architect Torsten Masseck, in collaboration with Engineering at La Salle (Universitat Ramon Llull) and a total of 14 entities between universities and private companies.SOLAR CUBE is an educative and experimental module on solar energy that aspires to create knowledge amongst students about the potential of solar photovoltaic energy in the field of architecture, helping to develop, in collaboration with companies, innovative solutions for the architectural integration of these technologies.

SOLAR CUBE

• CISOL developed in collaboration with Petritxol 6 Architects, authors of the project, an innovative photovoltaic sun screen for the municipal kinder garden “El Blauet” in Sant Celoni (Barcelona).

The project wants to make visible for the users of all ages the generation of photovoltaic solar energy through an attractive integration in the south façade of the building. A semitransparent, colored sun screen projects a vivid composition of light and shadow over the interior surfaces.

The project received the 2009 SOLAR AWARD by EUROSOLAR Spain.

Living Lab LOW3. Laboratory for energy efficiency, sustainable construction and renewable energies

ETSAV.

• LOW3 is a energetically self-sufficient solar house which, once converted into LIVING LAB at the Sant Cugat Campus allows the experimentation and evaluation of bioclimatic systems, renewable energy systems and low impact construction systems.

The laboratory counts with a 4,0 kWp photovoltaic installation, thermal collectors integrated in the south façade, a innovative low energy HVAC system and a domotic control system with sensors for temperature, relative humidity, CO2 concentration and contact sensors for openings.

LIVING LAB LOW3 fosters teaching and research activities in the field of solar architecture, building simulation and scientific performance evaluation of buildings.LOW3 has represented the UPC – Barcelona Tech in the international completion SOLAR DECATHLON EUROPE 2010.

Media-tic building

• Architect Enric Ruiz-Geli has designed an inflatable membrane façade from the Media-TIC building that will help it save energy and reduce carbon emissions by as much as 37 percent. The building will provide office space for several companies and organizations related to information technology.

• The cubical building provides a space of over 24,000 square meters. Designed by Cloud 9, the building features four façades to provide different levels of insulation. The inflatable façades use solar energy for inflation and deflation. The southwestern front of the Media-TIC uses a system that injects nitrogen to the longitudinal ETFE bags that are arranged along the building to generate a fog effect that reduces solar gain.

Information of the project_________________________Designer: Italian Architect Mario Cucinella;

Area: 20,000 sq. meter;Function: education, training, and research with a focus on energy

conservation and emissions reduction;Others: 40 meters tall, cost $32,000,000 , completed in 2006.

Plan:_________________________________________________________________Symmetrical in plan;

Central courtyard;Daylighting ;

Terraced south façade.

Goals of the building___________________

energy efficiency; low CO2 production;

healthy indoor air; water recycling and reuse;

resource savings in construction materials; minimization of environmental impact;

intelligent control systems for occupants and maintenance; durable materials.

__________________________________The green shape

The shape of the building evolves from a series of tests and simulations on solar radiation. The main starting points for the design team were a symmetrical U-shaped courtyard building stepping downwards towards the south. _________________________________________________

Envelope:________________________________________Different orientations,

different external facades,And different systems of ventilated facades.

Internal courtyard envelope_______________________double skin,glass louvers, intermediation

Materials:PVB, LOW-E glass

The east and west facades________________________double skin;

exteral silk-screen façade;light-shelves.

________________________________The north facades:cold winter winds;laster perforated aluminum panels;insulation panels

The stepping south-oriented facades______________terrace;

________________________The recycle system of rains

System of energy supplying________________________BIPV system;

electrical generators drived by gas generators;heat recovery system.

_____________THE INTELLIGENT MANAGEMENT SYSTEM

The SIEEB is dynamic. Layered onto the passive aspects of the building are a set of very innovative, intelligent, controllable systems that help the building reach its high sustainability mandate .Dynamic also means that the SIEEB can respond to occupancy, use and

time of day through the extensive use of sensors and override switches. Room temperature, lighting, and ventilation air are directly controlled by

occupancy, temperature, light, and CO2 sensors. These sensors direct building systems to turn on and off on a‘need’ basis which saves considerable energy. Controllability also means that occupants can tailor their space to suit their

comfort range which means that maintenance staff gets fewer complaint calls. ______________________________________________
