Retrofitting – Smart Buildings and Smart Cities

Retrofitting older buildings is a concept that city planners and managers are increasingly embracing as they face shrinking budgets, growing accountability, and aging or outdated infrastructure.


Retrofitting is being implemented worldwide in cities of all sizes to increase energy efficiency, reduce power costs, and lower greenhouse emissions. What most people don't realize is that the Internet of Things (IoT) has made it possible for retrofitting to go so much further than improving energy efficiency.




Building Infrastructure Management (BIM) systems can be retrofitted in many ways:

  • Internal Sensors 

With sensors capable of measuring the environmental features of enclosed spaces such as offices, hospital rooms or basements, buildings can be instrumented to measure and report any number of factors, including: temperature, humidity, movement, light, and noise. This data can be used to more efficiently deliver essential services on demand and track the use of individual areas.



External sensors can also be deployed to enhance the data gathered from internal sensors. To evaluate internal conditions, it is important to understand the external conditions. By correlating external and internal sensor data, a building’s complete environment can be monitored.


  • Protocol Adaptors

Another retrofit option is adding protocol adapters that allow communication with the cloud or fog architecture to Building Management Systems (BMS), like BACnet to HVAC and DALI for lighting. This allows data collection and  building system management to be handled securely from any location. Automated rules can be set up to manage those systems as efficiently as possible.


Smart Cities aren’t limiting retrofitting to building systems. Everything from water management to transportation to benefit from retrofitting.


Efficiencies can be gained in every area:

  • Reduced waste
  • Increased response time for repairs or servicing
  • Fewer wasted employee hours
