Deep Energy Retrofits

What are Deep Energy Retrofits?

A deep energy retrofit expands on the scope of a standard retrofit by taking a whole-building approach to understanding the impacts of energy efficiency improvements. While a standard retrofit addresses energy efficiency by upgrading old or outdated equipment in existing buildings, a deep energy retrofit furthers this process by analyzing all of the interactions between building systems, and aiming for savings upwards of 50%.


Deep Energy Retrofits as a Robust Energy Savings Market Driver

At a time of rising energy prices and supply fluctuations, high-performance building design and holistic energy improvements can achieve deeper energy savings in the new & existing building stock.

According to a study by The Rocky Mountain Institute, “our current building stock is dominated by these older, inefficient buildings—as many as 72% of U.S. buildings are over 20 years old”. Additionally, a 2012 joint report by the Rockefeller Foundation & Deutsche Bank Climate Change Advisors found that “improving energy efficiency by 30% in the nation’s pre-1980 building stock would result in $1 trillion dollars of energy savings over 10 years ….,a simple return on investment of over 358% over a decade”.


Energy Savings Measures – Deep Energy Retrofits

Deep energy retrofits go above and beyond standard retrofits with regards to energy savings achieved from implemented measures. These measures can include:

  • HVAC & Controls:  replacement or upgrades to heating, ventilation and air conditioning equipment including boilers, chillers, domestic hot water heaters, thermostatic radiator valves (TRVs)
  • Lighting:  replacement or alteration of lighting systems, including installing task-appropriate lighting, daylighting controls, sensors etc.
  • Building Envelope:  improvements and upgrades to insulation, including incorporating cool roofs, high-efficiency windows, green roofs, caulking etc.
  • Energy Management Systems (EMS):  installing EMS in buildings after energy improvements are completed ensures energy usage is properly monitored, measured and managed


Benefits of Deep Energy Retrofits to Building Owners & Managers

As a building owner, you will see many financial and non-financial benefits from a deep energy efficiency retrofit. Some of these benefits include:

  • Deep energy savings mined from existing buildings (>40% on average from baseline)
  • Increase in operating efficiency & fewer equipment breakdowns or downtime
  • Higher amount in incentives gained from higher energy performance
  • Potential for LEED certification, providing a boost in rental value
  • Visible improvement in occupant comfort levels & reduced attrition rate
  • Better building aesthetics


Growing Demand for Deep Retrofits from Financial Community

While the biggest challenges to financing energy retrofits have been identified as split incentives problems, insufficient credit and limited data on long-term energy performance, there has been a sizable uptick in funding & financing activity within the retrofit market. For instance, Bank of America launched its $20 billion clean investment strategy and $150 million going towards energy efficiency projects within its own buildings nationally. In 2011, Wells Fargo has provided or raised about $2 billion for energy efficiency retrofits1.
