Residential nZEB complex

Inca, Mallorca

An nZEB residential complex: in the heart of the Mediterranean

Comfort and sustainability are the two keywords of the project signed by architects Joan Fortuny and Alventosa Morell Arquitectes to build a new residential complex in the city of Inca, Mallorca, in the heart of the Mediterranean with high energy efficiency (Nearly Zero Energy Building, NZEB).

The photos were taken by artist and photographer Jose Hevia.

 

The technical pillars of intervention

The aim of the project was to ensure that the 54 apartments could have almost zero energy consumption, thus classifying themselves as an nZEB, with a consumption of only 0.64 kW/m2: this was possible thanks also to the use of the Mediterranean thermal mortar Diathonite Thermactive.037, applied with a average thickness of 40 mm throughout the vertical external envelope and in the horizontal faces of the balconies, to eliminate any risk of thermal bridges and to optimize consumption especially in summer, thanks to the high thermal capacity of the material in the warmer period of the year.
IBAVI, the public body that manages public facilities in the Balearic archipelago, has therefore delivered the 54 apartments to as many families who will be able to live in much more comfortable environments and with excellent indoor air quality.

Thermal Conductivity

λ = 0,037 W/mK

Thanks to the right mix of carefully selected natural raw materials, the product achieves very high thermal insulation performance

Breathability

μ = 3

Walls free to breathe. Thanks to the high permeability, indoor humidity is perfectly balanced, preventing the formation of mould and condensation.

Reaction to Fire

Class A1

Class A1 according to UNI EN ISO 13501-1. Zero flame generation and smoke emission.
