S E L E C T E D D E S I G N T E C H N I Q U E S :1. passive solar heating 2. thermal mass e�ects 3. natural ventilation

Barcelona have a very stable Weather, however to control and maintain the Comfort zone, it is important to control 2 things:

Solar HeatingNatural Ventilation

Generally, in Barcelona has North wind, with an average speed of 18 km / h both in winter and summer.The biggest change occurs Direction in the months of May, June, July and August (coinciding with the summer season, hot season), taking a direction you want West - South, with speeds that reach even the 25 km / h with a frequency of about 45 hrs usually produced monthly in the evenings.

The main objective is to work with the Wind as a Natural Ventilation system, so that the block / building can be protected from the northen cold wind in Winter and can be ventilated in Summer, to avoid the usage of mecanical ventilation system as Air Conditioners.

3_ energetic resources strategy

a_ from designThermal mass increase.Increase the surfacevexposed to the optimal orientation (ECOTECT).Natural ventilation system.Constant interior/ exterior relationship.

b_ from technologyELECTRICITY.Helix wind: in the north facade. x10 x 3.632 kW/y 72.640 kW/yGeothermal.Solar panels: in the roofs exposed to radiation.Piezo electricity: in access and dense circulation areas.Solar trees: for public/ outdor ilumination.

COOLING & HEATING.Geothermal calefaction with heating bomb in vertical con�guration.

PROCESS.Grey water recycling.
