Lessons learnt on modular renovation

Modular facade elements

Modular facade elements should combine all facade functions:

-thermal insulation, acoustical insulation, moisture safety, water and air tightness
-daylight and solar shading
-ventilation with heat recovery
-heating and cooling emission
-fire safety
-burglary protection
-architectural quality and visual upgrading of the neighbourhood
-extra features as heat storage (PCM’s)
-renewable energy production on facades (BIPV)

Modular facade elements for Demo buildings in Netherlands (top line), Latvia (middle line) and Estonia (bottom line)

Realization of 5 pilot sites

Prefabricated wall prototype developed by TUT

Prefabricated wall prototype developed by ZTC and RTU


Modular roof elements

Modular roof elements include productive outfitting for  renewable energy production (PV as well as solar collectors), and optional rainwater collection.

 PV-roof developed by Innogie  for Korsløkkeparken Demo building in Denmark

Modular HVAC units “house engines”

Modular ‘house engines’ The modular ‘engine’ combines all necessary installations and building services in one prefab platform unit, with easy plug and play connections for installing.

Smart Plug and Play Connectors

Smart Plug and Play Connectors for the modular components make it possible to reduce the renovation time.  Smart combinations of components and executions ensure extra performances for nZEB concepts, healthy indoor climate, safety, accessibility. The various components communicate by integrated wireless sensors and control components for performance diagnostics and control.
