Abstract
At the Department of Management and Engineering (DTG) of the University of Padova (Italy), the research team led by Prof. Renato Lazzarin, formed by the authors, worked during the first fifteen years of the millennium on different topics focused on sustainable technologies for energy production and utilization in buildings. Both experimental and theoretical/modeling studies were carried out, all sharing the evaluation of energy performance and sustainability: From the life cycle assessment and life cycle cost of building insulation materials in Italy, to the measurement of energy performance of a green roof, to the experimental measurement of different photovoltaic/thermal modules, to the development of a simulation software for direct and indirect evaporative cooling techniques, to the evaluation of different energy savings techniques for refrigeration and air conditioning in supermarkets, to an extensive analysis of the urban heat island effect in the city of Padova. The paper summarizes the main theoretical and experimental approaches, providing the methods adopted in each line of research. The main results of the studies conducted during the fifteen-year period are described and commented on, some of which were a well-established reference for the following literature.

Sustainability is related to natural materials and ecological issues
This paper describes the research studies and results in sustainable energy systems developed by Professor Renato Lazzarin and his research group during the 2000–2015 period, when he was working at the Department of Management and Engineering (DTG) of the University of Padova (Italy)
Such experimental measures were useful to tune the dynamic state, mono-dimensional model developed by the authors in Trnsys® (Section 2.2). Another line of research in sustainable systems was related to solar technologies, in particular thermal collectors and photovoltaic (PV). Literature on such a topic is very wide: Goel et al [16] presented a comprehensive review of solar thermal air heating systems, discussing the various designs and techniques used for performance enhancement; recently, Sarma et al [17] published a review on research work on improving the thermal performance of the solar flat plate collector; Singh and his group reported a review of solar energy and concentrating collectors and their application in power plants [18]; Zluwa and
Summary
Sustainability is related to natural materials and ecological issues. For example, in the past Buchanan and Honey compared energy consumption and carbon dioxide emissions to build different types of typical buildings (commercial, industrial, and residential) in New Zealand [1]. Such experimental measures were useful to tune the dynamic state, mono-dimensional model developed by the authors in Trnsys® (Section 2.2) Another line of research in sustainable systems was related to solar technologies, in particular thermal collectors and photovoltaic (PV). Literature on such a topic is very wide: Goel et al [16] presented a comprehensive review of solar thermal air heating systems, discussing the various designs and techniques used for performance enhancement; recently, Sarma et al [17] published a review on research work on improving the thermal performance of the solar flat plate collector; Singh and his group reported a review of solar energy and concentrating collectors and their application in power plants [18]; Zluwa and.
