2. Project Overview
Project founded under the work programme:
HORIZON 2020-WORK PROGRAMME 2014-2015
Leadership in enabling and industrial technologies
H2020-EeB-2014-2015 / H2020-EeB-2015
Topic: Innovative design tools for refurbishment at building and district level
(EeB-05-2015)
Participants: 13 Partners
4 RTO, 2 Universities, 2 IND, 3 SME and 2 Cities
Contact: contact@opteemal.eu
Optimised Energy Efficient Design
Platform for Refurbishment at
District Level
3. Research topic
• How to provide optimized building-district retrofitting designs
through a consistent integration of semantic representation of
the data from multiples sources: IFC models, CityGML models,
and contextual data (project, weather, occupancy, etc.).
Application of the research: the OptEEmAL platform
• Optimised Energy Efficient Design Platform for Refurbishment
at District Level
Three main components of the platform:
• District Data Model (DDM)
• Energy Conservation Measures Catalogue (ECMs)
• Automated generation of input data for simulation tools.
Project Overview: Context
5. Project Overview: What is a district?
1. Target buildings that will be refurbished
2. Surrounding buildings that interact with target buildings (shadows)
6. Project Overview: What is a district?
1. Target buildings that will be refurbished
2. Surrounding buildings that interact with target buildings (shadows)
3. District active systems connected to the buildings (district heating)
7. Project Overview: What is a district?
• Weather data
• Energy prices
• Socio-economic data
1. Target buildings that will be refurbished
