'Almost zero energy consumption building' means a building with a very high level of energy efficiency, self-supplied by renewable energy. The design strategy of this type of buildings is to limit the energy consumption in heating and cooling and achieve thermal comfort, through a catalog of passive systems with criteria of economic profitability.
Several building standards have been developed such as Minergie, Passive house or ASHRAE that make it possible to certify that a building is almost zero energy consumption when the energy demand, air tightness and the internal surface temperature of the envelopes are within characteristic values. Considering that a key factor, in order to achieve a building almost zero consumption, is to provide it with a wraparound with a high thermal insulation, these standards define the thermal transmittance values of the envelope necessary according to the climatic conditions of the Environment.
The objective of this article is to carry out a comparative analysis of the thermal insulation requirements of the different standards mentioned against the requirements established by the CTE, as well as to assess economically the impact on the costs of construction to get almost zero-consumption buildings in Spain
