Abstract: This document presents a detailed analytical and practical method for the estimation of battery life expectancy of a multi-hop mesh network. This network is composed by a set of MicaZ nodes using the XMesh routing protocol. The energy drawn for each of the tasks performed by the nodes is measured, and network topology and radio propagation are characterized in order to obtain accurate predictions of the lower bound for the battery duration of the nodes. This estimation is of paramount importance for field deployments, where energy is a scarce resource and replacing node batteries is a slow and costly process that can disable the network for relatively long periods of time.

Abstract: Building construction consumes energy and materials. Even if the scientific community has developed two main voluntary protocols of building construction evaluation (BREAM and LEED), the authors argue that one of the main factors that could be incisive for a better environmental sustainability is to stimulate all possible initiatives, including the reuse of recyclable building materials, that currently, is a modest application. Based on this, the paper is organized in two parts. The first is an analysis of the Italian situation with regard to urban redevelopment and energy saving, considering the number of intiatives and costs handed out for each region. The second evaluates and proposes new insights on the basis of the obtained results.
