C02 footprint of construction
Buildings generate 39% of
annual global CO2 emissions.
Building operations are
responsible for 28% annually.
Building materials and
construction (typically referred
to as embodied carbon) are
responsible for an additional
11% annually.

4. 4 www.seai.ie
Construction costs!
CO2 emissions from the building sector are the highest ever
recorded at almost 10 GtCO2
38%of global energy-related CO2 emissions including buildings
construction industry
35% of global energy use
Nearly 55% of total global electricity
Annual decarbonization progress almost halved from 2016 to 2019

Embedded energy, also known
as embodied energy, is defined
as the Energy that was used in
the work of making a product.

Circular economy entails
gradually decoupling economic
activity from the consumption
of finite resources and
designing waste second life.

Virtual Design & Construction/Material passport

17. 17 www.seai.ie
An RFiD-chip cast in a
concrete element for the Circle
House Demonstrator. The chip
links to a material passport
containing information about
the element, e.g.: the recipe for
concrete, the structural
integrity
of the element.

Build - Operational energy
Homes & Buildings
• Drive demand with new National Retrofit Plan
• Blend low-cost loans with SEAI grants to make retrofit affordable
• Open three more training centres for retrofit upskilling
• Introduce programme to decarbonise the heating and cooling sectors by 2050
• Phase out use of fossil fuels for space and water heating in all new buildings
• Roll out up to 2.7 TWh of district heating
• Promote use of electric heat pump or other low carbon technology in new and
existing residential and commercial buildings

BIM is information management for
buildings and construction
• What does your organization want to
achieve?
• How will you measure, monitor, and
continuously improve performance of
your asset?
• Who needs to engage? When? How?
The role of BIM in respect of
Operational Energy?

26. 26 www.seai.ie
What does your organization want
to achieve?
BIM enables simulation and
integrated analysis:
• Full lifecycle costing
• Systems and components
• Future policy requirements
• Carbon Budgets
• Waste Management
• Air and Water quality

27. 27 www.seai.ie
How will your organisation measure, monitor, and
continuously improve performance of your asset?
• Policy-based targets not tools
• 50-80 year lifespan
• Information flow
• S/w and sensors as enablers, not as
constraints
• Learn from user behaviour
• Machine Learning / Artificial
Intelligence
• Often not as predicted

28. 28 www.seai.ie
Who needs to engage? When?
• BIM enables early and ongoing
stakeholder engagement and
communication
• Clients
• Full supply chain
• As intelligent and informed
process participants
• At commencement
• & throughout the project via data
drops

29. 29 www.seai.ie
How to involve all stakeholders in BIM?
• ARISE / BIMCert
• BIMzeED
• Construction Blueprint
• DASBE – HCI-funded
• IGBC Learning Hub
• Digitization for a Circular
Economy (DiCE) Toolkits

There are a few areas where BIM helps in achieving
operational efficiency:
1. Asset Management.
2. Preventive Maintenance Scheduling
3. Efficient use of energy
4. Retrofits, Reconstruction & Renovation
5. Enhance Lifecycle Management
