APLICACIÓN DE UNA METODOLOGÍA DE DISEÑO ANALÍTICA, SINÉRGICA Y ADAPTATIVA PARA EL DISEÑO DE NZEB (EECN): MEDIDAS ACTIVAS

Abstract

The compulsory design of new buildings of nearly zero consumption, emanating from European directives, is increasingly close and requires the development of design methodologies adapted to the mainland climate. We firmly believe that a successful design of a nZEB can only be undertaken from a detailed analysis of the building and a holistic approach to the design of the building. Therefore, a methodology that has been developed is based on a passive model that limits the demand for thermal energy (obtained in previous steps of the methodology), studying the behavior of ACS installations individually, lighting (depending on the case) and air conditioning, with the aim of reducing the energy expenditure of non-renewable energy in operation of the building to a value close to zero and even null. An application of a methodology for a single family home is developed where the installed systems are evaluated by means of multiple annual simulations within the time intervals of a zonal model of the building using Cypecad MEP. The model take in to account the generation of solar thermal energy an photovoltaic, the use of geothermal, airthermal and biomass to design VRV installations of hyper-inverter, as well as other conventional solutions.
