CBECC-Com Nonresidential Compliance Software

The Building Energy Efficiency Software (BEES) Consortium

The Building Energy Efficiency Software (BEES) Consortium's mission is to advance open source software tools that may be used by Code Agencies, Rating Authorities, or Utility Programs in the development of energy codes, standards, or efficiency programs. Architects, engineers, and energy consultants may also use these tools to demonstrate compliance with the energy codes or beyond-code programs.

The consortium consists of two projects - one focused on Residential buildings and one focused on Nonresidential buildings. This site is dedicated to the Nonresidential project software, CBECC-Com. Information on the Residential project (CBECC-Res) can be found at: http://www.bwilcox.com/BEES/BEES.html

The CBECC-Com Team

This project is managed by NORESCO, LLC (previously Architectural Energy Corporation). The project team consists of a wide range of subject matter experts in the fields of energy standard development, the design of high performance buildings, and the development of building analysis software tools.


CBECC-Com Gap Analysis

In 2015, NORESCO worked with Southern California Edison to assess the capabilities of CBECC-Com. The project commenced with a rigorous analysis of design strategies used in conventional and low-energy buildings with a primary focus on comparing the full range of modeling capabilities of both EnergyPlus and CBECC-Com with respect to these strategies. The goal of this initial step was to identify gaps between modeling features supported by EnergyPlus that are not currently available in CBECC-Com. This report summarizes the gap analysis process and results, and provides a series of recommended actions to advance the capabilities of CBECC-Com.

CBECC-Com Title-24 Prototype Models

Download CBECC-Com Prototype Models

The prototype models were created using CBECC-Com 2016.3.0 SP1 version. The models use Climate Zone 6 for weather data and this can be modified by users for their specific climate zone. These models are intended for research purposes only and cannot be used for compliance/permitting. The models included in the download file are listed below:

CBECC-Com 2013 Software Development

This web page contains several documents related to the development and planning of the 2013 Nonresidential Compliance Software (CBECC-Com). On this site, you can view and download meeting agendas and minutes, presentations, review drafts of reports, and other project documents.
