Analysis and selection of indicators for a sustainability assessment method for school buildings based on SBTool ‐ PT

Nowadays, the sustainability of buildings has an extreme importance. This concept goes towards the European aims of the Program Horizon 2020, which concerns about the reduction of the environmental impacts through such aspects as the energy efficiency and renewable technologies, among others. Sustainability is an extremely broad concept but, in this work, it is intended to include the concept of sustainability in buildings. Within the concept that aims the integration of environmental, social and economic levels towards the preservation of the planet and the integrity of the users, there are, currently, several types of tools of environmental certification that are applicable to the construction industry (LEED, BREEAM, DGNB, SBTool, among others). Within this context, it is highlighted the tool SBTool (Sustainable Building Tool) that is employed in several countries and can be subject to review in institutions of basic education, which are the base for the formation of the critical masses and for the development of a country. The main aim of this research is to select indicators that can be used in a methodology for sustainability assessment (SBTool) of school buildings in Portugal and in Brazil. In order to achieve it, it will also be analyzed other methodologies that already incorporate parameters directly related with the schools environment, such as BREEAM or LEED.

Technical requirements for the use of C&DW recycled aggregates in municipal and rural roads and trenches

The use of construction and demolition waste (C&DW) in the construction industry is an important contribution to attain sustainability in the sector. The roads are among the civil engineering works which can use larger quantities of C&DW recycled aggregates. In Portugal, the limit values for the properties of C&DW recycled aggregates that can be used in the roads of Portuguese Road Network are defined by two Laboratório Nacional de Engenharia Civil (LNEC) technical specifications (TS), in accordance to Portuguese Decree-law no. 46/2008 of May 12th. Municipal and rural roads and trenches have specific characteristics that can enable the use of C&DW of lower quality than those required by existing LNEC TS, and even then ensuring an adequate performance. However, given the absence of specific regulation for those applications, the Portuguese Environment Agency requires compliance with the existing LNEC TS, which represents an obstacle to recycling a significant part of the C&DW, in particular at a local government level. This paper presents guidelines for the recycling of C&DW in municipal and rural roads and in trenches, which could be considered in a new forthcoming LNEC TS. In the preparation of the guidelines, the bibliography collected and analysed, the information gathered from the application of C&DW in a municipal and rural roads of a Portuguese municipality and in the roadways of a Portuguese resort, and the results of laboratory tests carried out on samples collected in the Portuguese municipality were taken into consideration.

Implementing a site waste management plan: a case study of a medium sized building contractor in Ireland

Construction and demolition waste management is becoming increasingly important on construction sites as landfill space in Ireland is rapidly depleting and waste management costs are rising. Due to these factors waste management plans are seen as a good response to minimising waste on site and this thesis aims to investigate how to implement such a plan on a practical case study as well as investigating the legislation regarding construction and demolition waste along with market availability for the reuse of the waste. Main contractor surveys were also carried out in order to gain a better understanding of current attitudes within the industry and these surveys are analysed in chapter five. A survey was also carried out among sub-contractors but this survey has not been used for this thesis as the study is on-going. The primary aim of this thesis is to examine the waste hierarchy opportunities that are available for construction and demolition waste in Ireland and to examine the effects of management strategies on construction and demolition waste reduction at the project level. A partnership was developed with Carey Developments Ltd in Co. Galway and an analysis of their waste management practices was undertaken. The primary case study will be the ‘Taylors Hill’ project in Co. Galway where work commenced in March, 2012. The secondary aim of the thesis is to develop specific waste minimisation strategies for the company and to develop a training tool kit for use on site.

Mafia in the ballot box

We study the impact of organized crime on electoral competition. Assuming that the mafia is able to bring votes to the supported party in exchange of money, we show that (i) the strongest party is willing to pay the highest price to secure mafia services; (ii) the volume of electoral trade with the mafia increases with political competition and with the efficiency of the mafia. Studying in detail parliamentary elections in Sicily for the period 1946- 1992, we document the significant support given by the Sicilian Mafia to the Christian Democratic party, starting at least from the 1970s. This is consistent with our theoretical predictions, as political competition became much tighter during the 1970s and the Sicilian mafia experienced an extensive centralization process towards the end of the 1960s, which increased substantially its control of the territory. We also provide evidence that in exchange for its electoral support the mafia got economic advantages for its activities in the construction industry.
