Question
Has a Deep Energy and Carbon Retrofit Study been performed on targeted building systems in the past 10 years?
Applicability
All asset classes
Owner/landlord occupied building
Tenant occupied building – all systems managed by the owner/landlord
Answer & Scoring
Select one of the following:
- Yes – Deep Retrofit Study = 6 points
- Yes – Major heating or cooling system retrofit completed in the last five years = 6 points
- No = 0 points
- Not Applicable – Tenant occupied building: Some or no systems managed by the owner/landlord = 0/0
Max of 6 points
Requirements
In addition to items covered under Question E1.3 Detailed Energy and Carbon Assessment, the Deep Retrofit Study must cover:
- Assessment of potential capital projects to reduce energy and carbon with multiple options, such as:
- Like-for-like replacement as a baseline
- A deep carbon reduction retrofit as the ‘highest savings’ case
- An optimized approach that meets multiple prioritized criteria
- Assessment of building electrical capacity and required service upgrades for each option
- Cost of carbon abatement ($/tCO2e lifetime) of proposed retrofit solution
- Detailed life-cycle cost analysis (LCCA) and risk assessment
- Identification of potential incentive opportunities
The assessment methodology should at least align with an ASHRAE Level III Audit.
A Deep Retrofit Study often includes the development of an energy model, which is a simulation of the retrofit scenarios proposed, to better facilitate effective decision-making.
Refer to ENERGY STAR for carbon emission factors. If other carbon emission factors are used, explain the reasoning and factors applied
OR
Provide evidence that the building completed a major heating or cooling system retrofit completed in the last five years.

Third-party
Value
- For some buildings, especially older buildings, larger interventions may be required to meet defined energy goals
- Building off E1.3a – Detailed Energy and Carbon Assessment, engage a qualified professional to perform a deep energy and carbon retrofit study
- This study includes all components of an ASHRAE Level II study as well as includes the creation of a whole-building energy model to analyze all building systems and how they interact
- This study will identify multiple options to upgrade a building to have energy and carbon savings beyond the operational level
- This is a good fit for teams that are looking to greatly improve their building performance through major building upgrades, are looking to pursue net-zero, or are considering building electrification
*Note that by completing the requirements of this question, a building will also meet all requirements of Baseline Practice E1.0a.

Description
A Deep Retrofit Study is typically focused on a specific system and provides in-depth analysis of carbon reduction options with schematics and specifications for the recommended solution. Align methodology with ASHRAE Level III Audit or equivalent.
Deep carbon retrofits go a step further than a typical detailed energy assessment, providing more in-depth analysis that focuses on a specific system or measure rather than taking a whole-building approach. In deep carbon retrofit studies, detailed assessments are performed on the available electrical capacity for all electrification measures. The study provides detailed cost estimates and a roadmap for implementation. It is the final step required to inform implementation decisions.
