2. Some data about the project
H2020 RIA Project under Industrial Sustainability call, Energy Efficient Buildings (topic LC-EEB-
02-2018 Building information modelling adapted to efficient renovation).
Starts: January 1st, 2019
Duration: 38 months
Budget: 5.56M€
Coordination: ATB Bremen

4. To provide effective and affordable
BIM tools that accelerate the
whole renovation life-cycle (from
data collection to project execution
and commissioning/delivery),
taking into consideration energy
efficiency and comfort parameters,
and involving all the actors in the
process (architecture studios,
designers, constructors, tenants or
public administration).
Main objective

5. To design a
Building Energy
Efficiency (EE)
model that
observes the
climatological
diversity of
European
countries and
their regulations
Intermediate objectives

6. ● Comfort is “that condition of mind that expresses satisfaction with the
environment and is assessed by subjective evaluation”.
● Subjective evaluation = Involvement of real dwellers.
● The Adaptive Comfort Models applied to climate data representing various
climatic zones, selected according to updated Köppen-Geiger classification.
● Adaptive comfort models like:
1. ISO 16813:2006, EN 15251 and prEN 16798-1: EUROPE
2. ISSO 74: Netherlands
3. GB/T 50785: China
4. ASHRAE 55-2017: global scope of applicability
5. …
Intermediate objectives
To design a Comfort model that observes the climatological diversity of European
countries and their regulations (indoor air quality, thermal comfort, acoustical
comfort, visual comfort, energy efficiency and HVAC system control)

7. To design an Ontology in the domain of Residential Renovation leading to EE &
Comfort gains
Intermediate objectives
• IFC and ifcOWL 4. BOT for espacial representation.

8. Intermediate objectives
To enhance interoperability proposing an adaptation of IFC’s standard creating a
specific Model View Definition (MVD) for the Life-cycle of Renovation Projects. To
feed standardisation bodies with the results.

9. To design a BIM Cloud-based
solution with features/services for all
the stakeholders in the renovation
life cycle of small or large projects:
Intermediate objectives
• Data acquisition/surveying with LiDAR,
photogrammetry (interior/exterior).
• Automatic semantic segmentation and
classification.
• Automated/assisted generation of models.
• Enhancement of models with BIM
resources.
• EE & Comfort simulations.
• End-users’ feed-back with AR/MR.
• Automated generation of tasks for
construction crews.
• Continuous monitoring of facilities.

10. To validate the
new renovation
life-cycle and the
platform in
experimental
pilots.
To assess them in
real life conditions
in social dwellings
of Extremadura
(Spain), obtaining
feedback from
real dwellers.
Intermediate objectives
Renovation
Simulations
Renovation tasks.
Management &
follow-up
Int/
ext

11. • Improve energy efficiency and comfort
of EU residential buildings (where 40%
of the stock was built before 1960 and
90% of it before 1990), leading to an
efficient use of resources and the
reduction of emissions (40% of the EU's
energy consumption, 36% of its CO2
emissions and 55% of its electricity
consumption belongs to EU’s stock of
residential buildings).
• Novel agile and transparent renovation
process centred on dwellers or tenants.
• Reduction of the costs of the
renovation process.
• Enormous market opportunity:
renovation projects account for 57% of
all construction activity [DG Internal
Policies, 2016].
