The working group also highlighted the role of buildings in the TIR as nodes and service
providers in an Internet of Things infrastructure. Buildings will be zero energy or plus energy
buildings within a district/eco-neighborhood through: optimizing the balance of efficiency
(insulation of the building envelope); the passive use of solar energy via south-facing windows;
the generation of electricity and heat on-site on the façades and roofs; solar energy, biomass
driven combined heat and power units (with gas motors or fuel cells); and using heat pumps to
generate heat from renewable electricity.
The overall aim of buildings is to protect the occupants from the weather, noise, and bad air,
and to provide a healthy environment which is well tempered, provides daylight and fresh air,
and enough space for people and goods. Buildings will also provide a perfect connection to the
outside world by ICT for entertainment, information, communication and education. And
buildings provide fresh water and facilities for disposal of waste, sewage water, etc. In addition,
urban farming is of growing interest and could be a service provided in, on, or around buildings.
