BIM for Energy Efficiency (EP107)

BIM for Energy Efficiency (EP107)

by Ioan Petri and Yacine Rezgui, University of Cardiff (23-Dec-2019)

Book Description

Global warming is driving the need to reduce energy consumption in buildings. Energy for the construction sector accounts for over 40% of Europe’s energy and CO2 emissions. A game-changing strategy is required to support the transition to cleaner and more cost-efficient practices.
BIM is already demonstrating effective collaborations across disciplines with a focus on total life cycle and supply chain integration. BIM also facilitates the collection and storage of information in an industry-compliant data store to benefit users. Informed implementation of BIM has the potential to pave the way to energy savings through: better supervision of energy flows and use in a building, and a new value proposition across the energy value chain during the operational stage.
This book explores ways in which:
- BIM data can be shared across supply chains and life cycle, taking into account a wide range of organisational, technical and legal aspects, including information sensitivity
- BIM can assist in the operations management of buildings and, in particular, help to address the endemic energy performance gap experienced in existing and new buildings, using artificial intelligence
- BIM can be used to enforce regulatory compliance with a focus on energy-related regulations
- BIM for energy efficiency can be scaled up to district and city level.
