Building Re-Tuning Updated Case Studies

Four BRT case studies have been updated: Parmenter’s Las Colinas, GSA’s Courthouse Annex and LBJ Education building (two in one combined document) and Georgia Tech’s TSRB. The case studies are also posted in the BRT training materials fileshare for use by BOMA and APPA. Additional content for the training from the case studies and material from CBEI’s building 661 have been added to the training modules.

Whole Building Diagnostic and Decision Support

CBEI conducted research to develop and demonstrate a library of diagnostics decision support tools that can enable cost effective diagnostics solutions for existing buildings. This report describes early results in successfully developing and demonstrating the effectiveness of diagnostics and decision support tools for subsystem diagnostics (RTU, DX, AHU-VAV and building envelope subsystems) and fault prioritization.

Two Case Studies Getting Value from Retrofit Demonstrations

Two case studies were prepared and submitted that incorporate CBEI experience with demonstration testbed sites: 1) Designing and Installing Measurement & Verification Systems: The CBEI Experience ; 2) CBEI Retrofit Demonstration Testbed: Novel CAV to VAV AHU Retrofit.

Three Case Studies

Building 661 (B661) was intended is to be the CBEI Headquarters and was designed to encourage collaboration, and to serve as a catalyst to demonstrate energy efficient retrofit innovations, advocacy, practice and commercialization strategies to radically reduce energy use in the existing commercial/institutional building stock. These case studies review the design, construction and initial operation of the building.

EDA Stakeholder Engagement Continued Effort

During BP5, CBEI worked with NREL and ICF to support the DOE Energy Data Accelerator (EDA). CBEI focused on the stakeholder engagement and communication strategy. The responsibilities involved collecting feedback from municipalities and utilities regarding their success and experience with data aggregation and access strategies. CBEI also assisted the EDA program with the regional aspect of the exit strategy at the end of the Accelerator.

Demonstration of a rapid and reliable

CBEI developed a web-based integrated design decision support tool which utilizes energy performance data generated through coupling of whole building energy simulation models with systematic search procedures and advanced data analysis techniques. This coupling process was extended with the introduction of a simulation-based numerical optimization framework for the minimization of life cycle costs for building enclosure materials and operational energy consumption for office retrofit cases. This integrated optimization program is highly automated (thereby saving user effort) and utilizes non-commercial, open-source and readily extensible existing toolkits.

Cost Effective Building Retrofit

CBEI developed and demonstrated a set of tools and approaches for generating and implementing building-specific control algorithms that minimize energy consumption and energy costs while maintaining occupant comfort. The general approach involves the use of model-based predictive control (MPC) with reduced-order models and inverse (data-driven) models for the building envelope, indoor environment, and plant.
