CIVIL-340: Study and analysis of energy systems

L'analyse critique de stratégies énergétiques nécessite de comprendre les différentes filières énergétiques impliquées dans l'approvisionnement en énergie et leurs impacts sur l'économie, l'environnement et la société. Le cours introduit à la formalisation ...

Description

This lecture covers the methodology of Life Cycle Analysis (LCA) applied to buildings in the Swiss context. It includes the different stages of LCA, the definition of objectives and system boundaries, and the inventory of resources and pollutants. The instructor explains the environmental impact assessment throughout the life cycle, the application of LCA to energy strategies, and the use of databases for LCA results. The lecture also discusses the allocation rules, system boundaries, and the environmental effects of emissions. It emphasizes the importance of functional units, energy consumption indicators, and the assessment of impacts on the environment. The presentation concludes with the application of LCA to buildings in Switzerland, considering standards like SNBS and software tools for simplified LCAs.

Energy policy

Energy policy is the manner in which a given entity (often governmental) has decided to address issues of energy development including energy conversion, distribution and use as well as reduction of greenhouse gas emissions in order to contribute to climate change mitigation. The attributes of energy policy may include legislation, international treaties, incentives to investment, guidelines for energy conservation, taxation and other public policy techniques. Energy is a core component of modern economies.

Database

In computing, a database is an organized collection of data (also known as a data store) stored and accessed electronically through the use of a database management system. Small databases can be stored on a , while large databases are hosted on computer clusters or cloud storage. The design of databases spans formal techniques and practical considerations, including data modeling, efficient data representation and storage, query languages, security and privacy of sensitive data, and distributed computing issues, including supporting concurrent access and fault tolerance.

Energy conservation

Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less energy for continuous service) or changing one's behavior to use less service (for example, by driving less). Energy conservation can be achieved through efficient energy use, which has some advantages, including a reduction in greenhouse gas emissions and a smaller carbon footprint, as well as cost, water, and energy savings.

Relational database

A relational database is a (most commonly digital) database based on the relational model of data, as proposed by E. F. Codd in 1970. A system used to maintain relational databases is a relational database management system (RDBMS). Many relational database systems are equipped with the option of using SQL (Structured Query Language) for querying and updating the database. The term "relational database" was first defined by E. F. Codd at IBM in 1970. Codd introduced the term in his research paper "A Relational Model of Data for Large Shared Data Banks".

Object database

An object database or object-oriented database is a database management system in which information is represented in the form of objects as used in object-oriented programming. Object databases are different from relational databases which are table-oriented. A third type, object–relational databases, is a hybrid of both approaches. Object databases have been considered since the early 1980s. Object-oriented database management systems (OODBMSs) also called ODBMS (Object Database Management System) combine database capabilities with object-oriented programming language capabilities.
