Building and fuel poverty, an index to measure fuel poverty: An Italian case study
No full textFuel Poverty is a big challenge for everybody: politicians, decision-makers, technicians, researchers, etc. In Italy, a strategy to solve fuel poverty involves action in order to reduce energy prices, the AEEG (Italian regulatory authority for electricity gas and water) has defined an Assist Tariff for poor people. Fuel poverty depends on family income and energy prices. Building energy performance also influences required energy consumption, and is a contributing cause of fuel poverty. Subsequently, it is possible to introduce a new Fuel Poverty risk Index, correlated to Building Energy Performance: the Building Fuel Poverty index. The Building Fuel Poverty Index (BFP) allows us to quantify how many buildings need direct action and/or just economic incentives.The index should be adopted in order to identify subjects that can afford to pay building energy refurbishment. The paper proposes an index in order to evaluate fuel poverty condition correlated to building energy performance
Historic Climate in Heritage Building and Standard 15757: Proposal for a Common Nomenclature
No full textResearch on the relationship between microclimate and heritage buildings or historic buildings has increased dramatically in the last few decades. Research has focused on indoor climate or indoor microclimate or the environment or micro-environment, and the field of these studies regards several variables, physical—air temperature, air speed, relative humidity—or chemical, dust, CO2, pollution, etc., all of which can have an effect or damage buildings or artifacts inside buildings. Moreover, all these variables should be monitored in a monitoring campaign following the standard EN 15757; in spite of this, scientific literature contains mistakes with regard to the words and objects of study. In this short contribution, the author proposes a common nomenclature in the research field of climate and microclimate in heritage buildings and heritage artifacts. A new nomenclature should be useful for the community of heritage scientists working on preventive measures to distinguish between climate and environment, or the object of study, e.g., the room (wall, wood structure, fresco, etc.) where the artifacts are or the air around them (painting, canvas, statue, piece of furniture, documents, books, etc.)

Building Physics and Thermophysical Performance
No full textThe evaluation of the performance of the building is part of the various phases of the design and construction processes. The verification of the compliance with the regulatory parameters or with the certification protocols, such as the Passive House certification—an activity that is present in every design phase—is one that, by means of the continuous interaction between form-technology-calculations-choice and so forth, leads to the achievement of the objectives. The architecture of the twenty-first century requires that, in the design of buildings, and as seen in the previous chapters, it is necessary to take into account several thermophysical parameters, Building Physics and Building Energy Performance. This chapter contains a description of the main thermophysical characteristics of the building envelope, with the aim of clarifying for the designer the physics meaning of the terms used in order to understand their relationship with architectural and technological choices
Indoor thermal comfort perception: A questionnaire approach focusing on children
No full textProviding a methodology for evaluating indoor thermal comfort with a focus on children, this book presents an in-depth examination of children's perceptions of comfort. Divided into two sections, it first presents a history of thermal comfort, the human body and environmental parameters, common thermal comfort indexes, and guidelines for creating questionnaires to assess children's perceptions of indoor thermal comfort. It then describes their understanding of the concepts of comfort and energy, and the factors that influence that perception. In this context, it takes into account the psychological and pedagogical aspects of thermal comfort judgment, as well as architectural and environmental characteristics and equips readers with the knowledge needed to effectively investigate children's perspectives on environmental ergonomics. The research field of indoor thermal comfort adopts, on the one hand, physical parameter measurements and comfort indexes (e.g. Predicted Mean Vote (PMV) or adaptive comfort), and on the other, an ergonomic assessment in the form of questionnaires. However the latter can offer only limited insights into the issue of comfort, as children often use different terms than adults to convey their experience of thermal comfort. The books aims to address this lack of understanding with regard to children's perceptions of indoor thermal comfort. The book is intended for HVAC engineers and researchers, architects and researchers interested in thermal comfort and the built environment. It also provides a useful resource for environmental psychologists, medical and cognitive researchers
Monitoring Campaign
No full textThe design and construction of the building are the most interesting aspects of the design project. Once the building is finished, the designer delivers it to the end users, the inhabitants, who are the ones able to verify whether or not the intentions of the design—low energy consumption and comfort—have been fulfilled. Following the approach of Lord Kelvin “if you cannot measure it, you cannot improve it”, with the aim of improving the skills of the designer and of the construction companies, together with the owner, it was decided to install a system of monitoring during the construction, to assess and measure the performance of what had been built. The monitoring campaign concerns the building envelope (roof slab and vertical wall) and the indoor microclimate of a room. In this chapter, we present the content and results of the monitoring campaign
Planning a Regional Energy System in Association with the Creation of Energy Performance Certificates (EPCs), Statistical Analysis and Energy Efficiency Measures: An Italian Case Study
No full textDirective 2002/91/EC EPBD introduced the Energy Performance Certificate (EPC) as a tool to guide the real estate market in the creation of products (buildings) with improved energy performances. The EPC’s information could be useful in the determination of relevant policies and also in studying the characteristics of the building resources of the territory. This paper presents a case study related to the EPC Database of the Emilia-Romagna Region in mid-northern Italy. The case study shows a way of elaborating the EPC information in statistical analysis evaluations with aggregate data, in order to measure a territory and then direct energy policies toward energy efficiency. A statistical approach was used to define a characteristic statistical indicator index of the EPC database, and compare the energy index with the bottom-up and top-down methods, in order to identify some energy policy scenarios
