Abstract

There is a growing awareness towards the use in architecture of construction materials produced in the area in which the buildings are to be implemented. The reduction of environmental impacts derived from the lower consumption of energy in transportation is significant. In addition, the materials used in the façades have special relevance in the value of the annual energy demand. This fact becomes more important in the case of emblematic buildings with social media impact, both for the quality of their design and for the functional contributions they can make. Sometimes, even for purely aesthetic reasons, the paradox of opting for constructive solutions with worse performance, worse aging, a higher cost of maintenance operations or a higher value of annual energy demand is established. In this research the Museum of Fine Arts of Castellón is analyzed, made with cast aluminum recycled panels as a finishing material on the façade. A comparison is made with the alternative scenario, ventilated ceramic façade, of having used large format ceramic panels, produced in the region, where the ceramic sector is a very important cluster. The reduction of the value of the annual energy demand by 12% is evaluated by the improvements established in the ventilated ceramic façade.

Highlights

The envelopes of the buildings are determinant in their annual demand, in their useful life, durability, thermal and acoustic performance, etc
The possibility of incorporating reflective enamels, which increase the reflectance of solar radiation by more than 250 %, prevents a greater thermal transmission in summer towards the inner layers of the enclosure, reducing the internal thermal admittance Y11 by 35%
If an occupation of 200 people is adopted, and a renewal air rate of 1 ren / h, for the calculation of the annual energy demand, this value is close to the actual energy consumption

Summary

Introduction

The envelopes of the buildings are determinant in their annual demand, in their useful life, durability, thermal and acoustic performance, etc. Some of them have shown very interesting results on the performance of ventilated façades, finished in various materials, such as stone, aluminum, bakelized wood [7] or porcelain stoneware [8]. In climates such as the Mediterranean coast, these systems are in summer much of the solar gain due to the heating of the soil layer thanks to the upward convection currents of the ventilated chamber. The application of a layer of continuous insulation on the outside of the enclosure at the height of the enclosures of a greater internal thermal capacity, controlling and storing the internal thermal loads, while avoiding thermal bridges
