Specifying Triggers

A critical step in planning a deep energy retrofit is determining the ideal situations for performing a whole-building analysis. For example, if you already have a major end-of-life replacement planned for your building, you may be able to add in energy improvements or adjust the planned improvement to make the building more efficient and to build value for your organization at minimal added cost. Also, as part of your portfolio planning, if you desire one or more efficiency measures to be rolled out across a buildings portfolio, it may be best to select an archetypical building for a deep energy retrofit.

We list many situations ideal for a deep energy retrofit below.



Adaptive reuse or market repositioning

Redeveloping an existing building will require significant capital expense to which the cost of a deep retrofit would be incremental and likely small in comparison.
End- (or near end) of-life roof, window or siding replacement

Planned roof, window and siding replacements provide opportunities for significant improvements in daylighting and efficiency at small incremental cost, providing the leverage for a deep retrofit that reduces loads and therefore costs of replacing major equipment such as HVAC and lighting.
End- (or near end) of-life HVAC, lighting or other major equipment replacement

Major equipment replacements provide opportunities to also address the envelope and other building systems as part of a deep retrofit. After reducing thermal and electrical loads, the marginal cost of replacing the major equipment with much smaller equipment (or no equipment at all) can be negative.
Upgrades to meet code

Life safety upgrades may require substantial disruption and cost, enough that the incremental investment and effort to radically improve the building efficiency becomes not only feasible but also profitable.
New Acquisition or Refinancing

New acquisition or refinancing at historically low interest rates can put in place attractively financed building upgrades as part of the transaction, upgrades that may not have been possible at other times.
Fixing an "energy hog"

There are buildings, often unnoticed, with such high energy-use or high energy-prices (perhaps after a major rate increase) that deep energy retrofits have good economics without leveraging any of the factors above.
Portfolio planning

As part of an ongoing management plan for a group of buildings, the owner may desire a set of replicable efficiency measures. These measures can be developed from the deep energy retrofit of an archetypical building.
