MULTI-UNIT BUILDING ENERGY WASTE (MURBs)


MURBs are the largest contributor to carbon emissions in the United States and Canada.


More than half of all Multi-Unit Residential Buildings were designed before 1980—an era when:

  • Insulation standards were minimal
  • Building envelopes were leaky
  • Air infiltration was extreme
  • Energy was inexpensive
  • Environmental impact was not considered


Competent building engineers and designers of the past always oversized heating equipment: larger baseboards, oversized boilers, and high-capacity heating plants. The path through thermal inefficiency was by way of over consumption of energy.

The Result

  • Buildings heat unevenly
  • Excess capacity wastes energy
  • Residents open windows to cool off overheated units
  • Utility costs rise
  • Carbon emissions increase
  • The challenge of the “stack-effect” inherent in multi-floor apartment buildings was further exasperated


In earlier decades, this was accepted. Tenants paid slightly more in rent for higher utility use, but energy was cheap and environmental concerns were minimal. Efficiency wasn’t the priority—avoiding complaints about cold apartments was the priority.

Today, everything has changed

  • Climate change is real and urgent
  • Governments mandate carbon reductions
  • Governments mandate minimum heating season temperatures
  • Tenants expect sustainable operations and infrastructure installations
  • Building owners face rising energy costs
  • Inefficient heating systems are no longer acceptable


Modern MURB management requires thoughtful, intelligent, data-driven control.
