ENERGY MANAGEMENT IN BUILT ENVIRONMENT TOOLS AND EVALUATION PROCEDURES

ISBN: 978-83-7775-660-7   173 stron format: B5 oprawa: miękka Rok wydania: 2022

There are three main pillars of sustainable development:

economic growth,
environmental protection
social equality.

Those pillars refer directly to the definition of sustainable development that was proposed by Gro Harlem Brundlant in the Report: "Our common future" in 1987: "Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs".

The idea of this book is to present tools and procedures that can be useful in the evaluation and optimization of the built environment related energy systems enabling their sustainable development. The built environment is regarded as manmade structures and infrastructures used by people for living, working and recreating on a day-to-day basis.

This book can be a support for second cycle environmental engineering students, consulting and facility management engineers dealing with built environment energy related systems.
