  3. 3. <ul><li>1. General Overview and methodology (1/5) </li></ul><ul><li>The POLYCITY project has been developed in Cerdanyola del Vallès during the last 5 </li></ul><ul><li>years. The demonstration activities related to the demand side are the design, </li></ul><ul><li>construction and monitoring of three buildings (one office building and two blocks of </li></ul><ul><li>social housing). </li></ul>POLYCITY FINAL CONFERENCE, VISIONS OF SUSTAINABLE URBAN ENERGY SYSTEMS 16th – 17th SEPTEMBER 2010
  4. 4. <ul><li>1. General Overview and methodology (2/5) </li></ul><ul><li>These buildings are a demonstration focus in the context of Alba Park, a new development </li></ul><ul><li>in the Metropolitan Area of Barcelona of over 300 hectares where more than 3,400 </li></ul><ul><li>households (1,300 public and 2,100 private) will be constructed over the coming years. </li></ul><ul><li>Thus, POLYCITY has, in Cerdanyola, an important replication area for direct transfer the </li></ul><ul><li>results of the experience . </li></ul><ul><li>The Alba Park urban development and planning documents reflect a clear commitment to </li></ul><ul><li>reduce the energy and C02 emissions related to the new buildings and urban areas. In this </li></ul><ul><li>sense the Alba Park area planning regulations and concepts make it obligatory for all the </li></ul><ul><li>new buildings to include passive and active energy efficiency measures in all constructions. </li></ul>POLYCITY FINAL CONFERENCE, VISIONS OF SUSTAINABLE URBAN ENERGY SYSTEMS 16th – 17th SEPTEMBER 2010
  5. 5. <ul><li>Is important to note that the main results of the POLYCITY experience in Cerdanyola del </li></ul><ul><li>Vallès will be completed by the end of April 2011 when the 3 building monitoring data </li></ul><ul><li>and the results of the interaction process with tenants will be available for analysis and </li></ul><ul><li>processing. </li></ul><ul><li>Finally it is important to consider that POLYCITY Cerdanyola is a very interesting pilot </li></ul><ul><li>experience for the new created Catalan Housing Agency (Parliament of Catalonia, </li></ul><ul><li>2009) in relation to developing its energy efficiency and C02 reduction policy. The </li></ul><ul><li>Climate Change Action Plan for Catalonia (Generalitat of Catalonia, 2009) establishes </li></ul><ul><li>an annual target reduction of 0.7 million tonnes of C02 for buildings. </li></ul>1. General Overview and methodology (3/5) POLYCITY FINAL CONFERENCE, VISIONS OF SUSTAINABLE URBAN ENERGY SYSTEMS 16th – 17th SEPTEMBER 2010
  6. 6. <ul><li>The monitoring data provided in 2010 and 2011 for the three POLYCITY demostration </li></ul><ul><li>buildings will be very useful to analyse the effectiveness, in terms of energy efficiency </li></ul><ul><li>and C02 emissions reduction, of the architectural and interaction measures implemented. </li></ul>1.

  7. 7. <ul><li>1.General Overview and methodology (5/5) </li></ul><ul><li>The methodology used can be structured along the two lines of work described initially: </li></ul><ul><li>Energy demand and C02 emissions reduction related to the new passive measures implemented. </li></ul><ul><li>The methods used can be ordered according to three main typologies </li></ul><ul><li>Simulation methods (CALENER, ENERGY PLUS, DESIGN BUILDER) </li></ul><ul><li>Monitoring systems (ADVANCED for 8 dwellings offering the segmented energy consumption; GENERAL for 77 dwellings with total electric and gas consumption for each dwelling). </li></ul><ul><li>Cost benefit analysis (Integrating all the data produced). </li></ul><ul><li>Innovative interaction model in order to increase tenant’s awareness and responsible energy use. In this case PARTICIPATORY methods are being used in order to facilitate the interaction and the transparency in the relations between public administration and new tenants. </li></ul>POLYCITY FINAL CONFERENCE, VISIONS OF SUSTAINABLE URBAN ENERGY SYSTEMS 16th – 17th SEPTEMBER 2010
  8. 8. <ul><li>2. Results related to energy demand and efficiency (1/8) </li></ul><ul><li>Different innovative passive measures have been applied in the three buildings. At the Synchrotron office building the main measures that have been implemented are: </li></ul><ul><li>Glass with low thermal transmittance (south façade). </li></ul><ul><li>Connection to the district heating and cooling high efficiency network. </li></ul><ul><li>Extra insulation. </li></ul>POLYCITY FINAL CONFERENCE, VISIONS OF SUSTAINABLE URBAN ENERGY SYSTEMS 16th – 17th SEPTEMBER 2010
