Descrizione
This book is addressed to a rather wide range of potential readers. Designers will find useful information for accurate and economic sizing of equipment such as boilers, both for heating and for Domestic Hot Water production. Energy Managers will be able to perform “ex ante” efficiency assessments of technical solutions as proposed by architects and builders. Regulation and standardization bodies will have the opportunity to consider simplifications to energy efficiency regulation, which might make them simpler (and less costly) to apply, with no significant loss of accuracy. Academia will be proposed a detailed heat transfer physical model that can lead to substantial saving of calculation time. Individual parts of the book are independent of one another, so that readers can focus on the topics in which they are mainly interested.
Autore
Giuseppe Dell’Olio has been working in the energy sector since 1993, initially with ENEL (the Italian electricity authority at that time) and later as an expert in energy efficiency projects developed by GSE in collaboration with Italian Ministries and Agencies. He joined GSE (Italian agengy for subsidizing energy efficiency and renewable energy production) in 2005. Since then, his interests include: Energy efficiency in industry and buildings; smart metering applied to natural gas, electricity, heat; smart grids and microgrids; combined heat and power production (CHP or cogeneration plants); district heating and district cooling; renewable energy sources, both for electricity and for heat; distributed Energy Resources (DER). On these topics he has published a number of scientific papers accepted in international meetings or in technical journals, as well as five books. He cooperates with CEI (Italian electrotechnical commitee), CENELEC (European Electrotechnical Committee for Standardization) and IEC (International Electrotechnical Commission).
