Determination of potential for architectural integration of active sun collection in constructive typology of low height in the heritage center of Andean cities. Case of Study Cuenca, Ecuador.

The Andean cities in height near the equatorial line, have particular characteristics and opportunities to implement energy self-supply with renewable energy. Solar collection under constant non -seasonal irradiation implies generation capacity stability, unusual positive situation in the world. The potential implementation of an urban intelligent energy supply network (Smart-Grid) implies a very valid option due to the stability of irradiation in the aforementioned context, seasonal variability implies the largest barrier to achieve neutral cities in energy balance (Mikkola & Lund, 2014). The minimal demands for thermal environmental conditioning implies a relevant opportunity to achieve Net Zero and Plus-Zero buildings (buildings that produce so much or more energy than they consume). For this, it is necessary to decipher the technological abilities that can be incorporated into buildings with aptitude to resolve characteristic energy demands. This study raises an analysis of the most common typology in the city of Cuenca, Ecuador, in its historic center, buildings of between one and three plants of residential-mixtos use, with patrimonial connotation. The capacity for energy self -supply and a possible delivery of surpluses as a contribution to the public network is measured. An information lifting of energy demands is executed in a sample representative specifically of its roofing bays, determining the available space. The collection is considered in the totality of available surface as well as only in the less visible externally (internal bay) sectors. Thermal solar collectors (ST) and photovoltaic (PV) are integrated architectally. A dimensioning in daily and monthly periods of production-demand in temporary balance is executed. The renewable energy integration capacity in Smart Grid is pre-dimensioned. Finally, the consequent effects of the typical collectors deployed in heritage buildings are analyzed. However, there are collectors for architectural integration with tile configuration as an alternative (IEA & SHC, 2014).
