Energy Consumption vs Time graph for typical commercial building behavior

Building Re-Tuning


The Consortium for Building Energy Innovation (CBEI), the Building Owners and Managers Association (BOMA) International, and the U.S. Department of Energy (DOE) and have joined together to develop a deployment model for commercial building re-tuning training. This collaboration will result in increased opportunities for building operators and engineers nationwide to learn the building re-tuning process and methodology and use it to identify and capture energy savings in their buildings.

Building re-tuning is a systematic process to identify and correct building operational problems that lead to energy waste. It is implemented at no or low cost other than the labor required to perform the re-tuning process. Re-tuning may include adjusting thermostats for actual occupancy patterns or small, low-cost repairs such as replacing faulty sensors or caulking openings in the building envelope.  By proactively utilizing the energy savings opportunities taught in the re-tuning training, operations staff can save between 5 and 20 percent of all energy used in the building.

The BOMA/CBEI/DOE partnership is offering re-tuning trainings at two BOMA local associations (BOMA Wisconsin and BOMA San Diego) utilizing a train-the-trainer approach. This initial year, the program curricula is focused on re-tuning buildings without a building automation system (BAS). In following years, the training course will cover BAS with additional material on trend logging and analysis to inform additional efficiency opportunities. Attendees will help bring re-tuning training to scale by using the material to train other end users, such as facilities engineers, either within their own companies’ building portfolios or within their local community. 

Pacific Northwest National Labs initially created the building retuning training and has online interactive training and extensive resources. Building Re-Tuning case studies can be found here.

Retrofit Roadmaps

Integrated Design Advanced Energy Retrofits Overview

As an introduction to the material and concepts of Integrated Design Advanced Energy Retrofits, the Integrated Design Advanced Energy Retrofit Roadmaps Overview for Small to Medium-Sized Commercial Buildings walks the reader through basic ideas that will be repeated throughout the suite of ID AER documents. For those interested in possibly pursuing an Integrated Design Advanced Energy Retrofit, a short quiz assists in identifying the reader with an initial glimpse into what scale of retrofit may be appropriate for their project.

The Saving Energy in Leased Spaces Toolkit

The Saving Energy in Leased Spaces Toolkit is an online toolkit provides resources, training and tools – primarily targeted toward commercial building owners, managers and tenants – organized into three core areas that track the tenant leasing process:


  • Saving Energy in Existing Leases
  • Saving Energy in New Leases
  • Saving Energy during Tenant Improvement

Each of these sections of the toolkit contains the following three elements:

Training Module: Each roughly one hour course focuses on three key areas where tenants, landlords and building owners can save energy: plug and process loads; lighting; and HVAC. The course goes through the value proposition for taking on an energy efficiency upgrade to an existing space; maps out a process for implementing such an upgrade; and provides detailed explanations of key technical activities that tenants can undertake to improve the energy performance of their leased spaces.


Tools and Checklists: Embedded interactive checklists that tenants can use to inventory their key plug and process loads and generate an estimate of the energy that can be saved by eliminating or upgrading them.


Resource Library: Each Resource Library contains a variety of documents specific to the area of energy savings covered in the training module. These documents – derived from a range of public, private and non-profit sources –provide additional information on plug loads and the current state-of-practice in improving the energy efficiency of existing leased space.
