RE-COMMISSIONING OR RETRO-COMMISSIONING

Restoring your building to its original performance level and sustaining your building at that high level.

RESTORINGIntelligence - Ongoing analysis and improvement

Intelligence is the ongoing analysis and improvement that makes the difference

SUSTAINING

Building performance deteriorates over time without service

Building performance starts out how you design itYou can improve it to bring it back to original lifeIt further degrades over time without measures to sustain performanceAspire to sustain but look for opportunities to make it even better than it was originally designed

Sheet Wraps

• Thin, non-perforated sheet fastened to substrate

• Requires sheathing back-up (exterior drywall)

• Insulation is exposed to the exterior conditions

Peel and Stick

• Self Adhered sheet membrane adhered to substrate

• Need Exterior Drywall

• May need a primer

• Insulation is exposed to the exterior conditions

Fluid Applied Full Coverage

• Site applied liquid (typically sprayed or troweled)

• Requires supporting surface

• Insulation is exposed to the exterior conditions

Sheet and Fluid Applied Flashing

• Combines rigid, sheet installation with fluid applied seams

BASIS OF DESIGN

+Climate Zone 4 | R13 + R7.5ci+5/8” Exterior Gypsum Sheathing+Separate Air & Weather Barrier

THERMAX WALL SYSTEM RE-DESIGN

+New Configuration | R13 + R10ci- Eliminate Exterior Gypsum Sheathing- Eliminate Separate Applied Air &

Weather Barrier

SYSTEM COMPARISON

The original design had condensation potential.

The Thermax Re-design eliminated that potential while increasing thermal performance

VFD RETROFIT STRATEGY

55

• Average store has (6) Sales Floor ventilation RTU’s with supply fans (usually 3 or 5 hp) running 24 hours a day at full speed.

• Typical ventilation RTU runs over 4,000 hours a year outside heating cooling demand times.

• Opportunity for significant saving installing for VFD’s on Sales Floor, 24 hour, ventilation strategy.

VFD RETROFIT STRATEGY

56

• Slowing a ventilation RTU supply fan from full speed to 33% speed in ventilating mode results in a 96% reduction in motor kW.

• Outdoor air damper required to be proportionately opened beyond minimum setting when fan speed slows.

VFD RETROFIT STRATEGY

57

On larger RTU’s, VFD’s were mounted in an external cabinet

On smaller RTU’s, VFD’s were mounted in the existing control cabinet.

Control modules were added to allow our EMS to communicate with the VFD’s to write commands and read operational data.

VFD RETROFIT RESULTS

58

2017 • VFDs installed in 125 stores with 761 RTUs• Estimated annual savings: 13,500 kWh ($1,620) per

unit and 10M kWh ($1,200,000) overall.• Average Simple Payback of 2.2 years.

Total Program (2014-2017): • Whole program VFDs installed in 2,360 RTU’s • Estimated annual savings of 48M kWh ($5,700,000).
