TKI-EnerGO: Energy in the built environment
Energy is a fundamental source for our current
civil society. It provides comfort and facilitates
our day-to-day living and activities.
Sustainability of cities is directly related to the
sustainability of our energy system.
Energie in de Gebouwde Omgeving / Topsector Energie
Our energy dependence
In 100 years we developed an energy system to
secure 24/7 supply of ample fossil resources
Now transformation is required as:
• Geopolitical circumstances endanger supply
• Climate change forces us to limit to 2Ds scenario’s
• Resources are depleting

Changing from a traditional energy system……

Energie in de Gebouwde Omgeving / Topsector Energie
To a fully transformed energy system of the future!

Energie in de Gebouwde Omgeving / Topsector Energie
From a central supply to a decentralized system

The fundamental changes
Energie in de Gebouwde Omgeving / Topsector Energie
Changes on buildings-level
Energy conservation / envelope
-Integrated building elements to conserve
and generate energy
-Energy management
Renewable energy production
-Solar, geothermal, bio, etc
-Both on district and building level
-Storage will be key
Consumer behavior
- More interaction
- Smart Grids
Energie in de Gebouwde Omgeving / Topsector Energie
Changes on district level – changes in grids
Changing the system from one-way
to a two-way system
-Capacities
-Smart Grids
-Governance
-Storage
Energie in de Gebouwde Omgeving / Topsector Energie
Large scale renewable energy production
Dynamic /variable supply sources
-Wind at Land / Wind at sea
-Large solar farms
-Bio-energy
-Deep Geothermal
Storage and conversion
-Pumped hydro
-Power to gas (P2G)
-Power to heat (P2H)
Energie in de Gebouwde Omgeving / Topsector Energie
Shift in heating source
Energie in de Gebouwde Omgeving / Topsector Energie
This will change our homes…..
Energie in de Gebouwde Omgeving / Topsector Energie
And it will change our working environment
Energie in de Gebouwde Omgeving / Topsector Energie
EnerGO scope: focused RDD to support this transition
Energy production, storage and
distribution on district level
Multi-functional
building elements
Compact energy
conversion and storage
Energy Management ,
Energy Performance
and control
