Energy Exchange: Federal Sustainability for the Next Decade2

• Focusing on two hands-on training programs for building operators with documented energy and cost savings:– Building Operator Certification (BOC)– Building Re-Tuning Training

• Federal Buildings Personnel Training Act and its relevance to you

Session Overview


1. Decide whether you, a co-worker or subordinate is a good candidate to attend BOC and/or BRT

2. List 3-5 common energy-saving opportunities that are discovered during building re-tuning

3. Make a persuasive case to your management or decision-makers about the value of investing in building operator training

Review Session Objectives


• Other than this conference, when was the last time you participated in training?

• How many of you think the building(s) you work in are energy efficient? Very? Somewhat? Not so much?

• Do you think the savings from training facilities staff generally result in energy savings of?– 0-5% – 5-25% or – 25-50% – 50% or greater

Questions


• Nationally recognized certification• Project-based• Short quiz assessments• Apply class learning to the building you are in• Main focus is energy efficiency• 72 hours, typically over 7 months

BOC – The Basics


Building Re-Tuning is identifying and implementing no- and low-cost improvements to increase building energy efficiency. The training is targeted at people working in buildings who can learn to re-tune their buildings• Training formats:

– Online on-demand (2-6 hours)– In-person (1-2 days)

• Training options:– Small building without BAS– Large building with BAS

BRT – The Basics

Energy Exchange: Federal Sustainability for the Next Decade

FBPTA - Requirements of the Act

• Core Competencies for Federal buildings Personnel

• Recommended Curriculum and Continuing Education

• Annual updates to Competencies and Curriculum

• Compliance by all Federal buildings personnel

• Method for contractor compliance

“…core competencies …relating to building operations and maintenance, energy

management, sustainability, water efficiency, safety (including electrical safety) and

building performance measures.”

Meta-Analysis of ~100 Buildings

• What are the common re-tuning measures?• What are the expected savings, if a building is

re-tuned?• Analyzed over 100 buildings, documented the

common re-tuning measures– Documented whole building energy savings for a

subset of the buildings (~25)

~25 buildings

~50 buildings

~30 buildings

Classification of Re-tuning Measures

15

Level of Effort

Potential Savings

For example, most desirable measures to implement are those that yield high savings but require low effort

Scheduling measures fall in this category

Meta-Analysis: Common Measures

– Lack of proper schedules for HVAC and lighting systems

– Lack of schedules for exhaust fans or fans running during warm-up mode

– Lack of night set backs– Lack of occupancy-based

controls for common areas (conference rooms, kitchen, etc.)

– Lack of photo sensors or sensors in the wrong locations for exterior lighting controls

– Lack of automatic lighting controls

– One or more faulty sensors

16

Improper air flow sensors or stuck zone dampersImproper minimum outdoor-air setting during morning warm-upLack of static pressure or discharge temperature reset on AHUsLack of chilled/hot water temperature resetLack of differential pressure reset on chilled/hot water distribution loopImproper heating/cooling set points or dead bands

Almost every building had some re-tuning measures to consider

Meta-Analysis: Distribution of Re-tuning Measures

• Although the sample is biased towards office buildings, there appears to be no difference in the distribution of re-tuning measures by building type, vintage, and size

Meta-Analysis: Summary

Meta-Analysis: Summary (cont.)

• Annual energy savings ranged between 2% to 26%, with a median savings of 15%

• Annual normalized cost savings ranged between 0.0$/sf to 0.6$/sf, with a median savings of 0.12$/sf

• If all re-tuning measures identified were implemented, the savings could have been even larger

GSA Retuning Case Studies


LBJ Department of Education Headquarters• Built in 1961• 550,800 rsf• Full modernization in 1996• HVAC commissioned in 2010

GSA Retuning Case Studies

William Bryant Courthouse Annex• Built in 2005• 264,842 rsf• 9 courtrooms, 19 chambers and office space for court functions


Retuning with BAS vs Without BAS


In the first four months since re-tuning:• LBJ saved 21.7% on electricity usage• Annex 8.2% on electricity usage

Electricity Savings – LBJ & Bryant


Best aspect of course was “seeing actual equipment and hearing/seeing ‘real life’ issues/problems and how they were solved.”
