Data on external walls from a multi- objective simulation for cold climates. Data are related to the multi- objective optimization process applied to the. EN ISO (E) 3 Foreword This document (EN ISO ) has been prepared by Technical Committee ISO/TC 163 'Thermal performance and energy use in the.
The data given in the following paper are related to input and output information of the paper entitled Design method of high performance precast external walls for warm climate by multi-objective optimization analysis by Baglivo et al.. Previous studies demonstrate that the superficial mass and the internal areal heat capacity are necessary to reach the best performances for the envelope of the Zero Energy Buildings located in a warm climate. The results show that it is possible to achieve high performance precast walls also with light and ultra-thin solutions.
Yodot Rar Repair Full. Atheros Modem. A multi-criteria optimization has been performed in terms of steady and dynamic thermal behavior, eco sustainability score and costs. The modeFRONTIER optimization tool, with the use of computational procedures developed in Matlab, has been used to assess the thermal dynamics of building components.
A large set of the best configurations of precast external walls for warm climate with their physical and thermal properties have been reported in the data article. Analysis of optimal solutions, i.e.
The best compromise among the various objectives and all the constraints imposed on the problem. The selection of building materials is considered as a multi-objective decision; the designer can choose the appropriate solution for his work from a number of possible configurations of the external wall. The modeFRONTIER optimization tool, with the use of computational procedures developed in Matlab, has been used in order to calculate the thermal dynamics performances of building components. The optimization has been carried out in terms of steady thermal transmittance, periodic thermal transmittance, decrement factor, time shift, areal heat capacity, thermal admittance, surface mass, small thickness, eco sustainability score, light-weight and costs. The superficial mass and the internal areal heat capacity are necessary to reach the best performances for the envelope of the Zero Energy Buildings located in a warm climate. The analysis of the results suggests that, to obtain high performance walls for warm climates, it is strongly required mass in the inner side that is able to increase the thermal inertia and gives to the wall the ability to store and discharge with a certain time shift the flow of the heat.
For this reason, concrete is disposed in the first layer (internal side). Several authors show the benefits of thermal inertia and evaluate how the walls thermal properties influence a building׳s energy performance. In particular, by the right choice of isolation and an optimal thickness is possible to reduce the heat flow that crosses the multi-layered wall and the energy consumption of the entire building.
The results show that it is possible to reach highly performing behavior also with limited thicknesses, less than 40 cm, using ecological materials available today on the market, and achieve high thermal dynamic performances for hot climates.

This study, defining a method for the choice of construction materials sequences in the precast external walls, contributes to the reduction of energy consumption in a building and supports the design of Nearly zero-energy buildings.
ISO specifies the characteristics related to the dynamic thermal behaviour of a complete building component and provides methods for their calculation. It also specifies the information on building materials required for the use of the building component. Since the characteristics depend on the way materials are combined to form building components, ISO is not applicable to building materials or to unfinished building components. The definitions given in ISO are applicable to any building component. A simplified calculation method is provided for plane components consisting of plane layers of substantially homogeneous building materials. Annex C provides simpler methods for the estimation of the heat capacities in some limited cases.
