Marshall Space Flight Center Building 4487

Energy, LEED, and Retrocommissioning Analysis

Location: Hunstville, AL
Owner: Marshall Space Flight Center

As a part of the comprehensive consulting services provided to Marshall Space Flight Center (MSFC), we provided Energy Audits/Assessments, Retro- Commissioning (RCx), as well as and LEED EB evaluations. The Scope of Work for RCx was described as a two-phase process. Phase I of the RCx was a preliminary study of a 323,262 GSF administration and laboratory building on the installation of the MSFC in Huntsville, AL. The findings of the Phase I investigations were the foundation for the development of a comprehensive RCx Plan. This RCx Plan was the major deliverable of the Phase I study and investigative phase.

The scope of work for this project included a bundle of services requested by NASA that the would bring this specific NASA facility in compliance with all applicable Federal legislation, Presidential Executive Orders, and NASA Guidelines (such as NPG: 8570.1, “Energy Efficiency and Water Conservation Technologies and Practices”) for the purpose of retro-commissioning (RCx) various energy systems within existing NASA facilities.

Phase I, (i.e., RCx study) consisted of the following elements:

Planning and existing documentation review;
On-site investigations of all HVAC,
Domestic Water Heating and Lighting systems and components;
Facility Performance Analysis and Performance Baseline Establishment;
Systems Diagnostic Monitoring;
Development of Functional Performance Testing procedures to be utilized in the Phase II RCx project, once funded; and
Scoping meeting with key NASA personnel to present the RCx Plan for Phase II.

On-site evaluations of the HVAC equipment throughout this building included a total of 45 AHUs, 474 VAV terminal units, associated BAS, water distribution pumps and several steam-to-water heat exchangers. Documentation of each piece of equipment’s condition and operability was made. As there were no documents available that specified the current facility requirements of the space, preliminary CFR documentation was generated that would be used as the foundation for the Phase II RCx evaluations. There were also no Sequences of Operation formally written for each piece of HVAC equipment and system in the building by the Utility Management Control System department; therefore, detailed Sequences of Operation for these systems were written by the SEA RCx team as a part of this Phase I project.
