Webinar - Time-of-Week & Temperature (TWOT) Modeling: Qualifying Impact in your M&V Analysis

April 13, 2026 2:00 PM - 3:00 PM (EDT)

Description

Developed by the Lawrence Berkely National Lab (LBNL), TOWT modeling helps M&V professionals understand complex energy consumption patterns. In an Option C Whole Facility M&V approach, weather, occupancy and operational schedules all influence consumption, but traditional M&V models often oversimplify these relationships. The TOWT separates weather-dependent and time-dependent loads to highlight variable consumption patterns by hour and day of week. For ESCOs, performance contracting depends on accurate, defensible M&V, since verified savings directly determine project payback and financial risk. TOWT models stabilize annual savings results, which protects guaranteed savings and reduces the likelihood of shortfalls or disputes. This has a direct impact on project payback, since savings drive cash flow used to repay capital-more reliable savings mean faster, more predictable payback and lower financial exposure for the ESCO.

Presenters:

Lucas Born, Manager, Program EM&V, Power Takeoff and Rachel Hartley, M&V Account Executive, Power Takeoff

Learning Objectives:

1. When should a TOWT model be used in your MVanalysis?

2. What benefits come from using a TOWT model in a performance contract?

3. What is a TOWT model designed to address?

4. How many hourly patterns can you create with this type of M&V model?

NAESCO has submitted this webinar to the AIA for 1 CEU approval.

NOTE: Beginning in 2023, all NAESCO webinars will be offered to all attendees at no cost. Recordings and slides will be available to members only, after the webinar.
