What is mechanical insulation? Thermal insulation used on piping, equipment, and all types of mechanical systems to:
` Save energy
` Reduce greenhouse gas emissions
` Control temperature
` Control condensation
` Protect personnel
The Forgotten Technology that Saves Money & Energy for Schools
Why is mechanical insulation the “forgotten technology?”
` In a 4-year mechanical engineering program, less than 1 hour is spent on thermal insulation
` Insulation is often “value engineered” as part of a mechanical contract
` Easy to forget about—no knobs, buttons, gauges or computer monitoring
` LEED and other green rating systems don’t allow mechanical insulation to be used on a standalone basis for credit
QUESTIONWhat percent of all mechanical insulation is missing or damaged?
10-30%of all installed mechanical insulation is missing or damaged

The mechanical system at the old high school was deteriorating due to shoddy installation and maintenance
of the mechanical insulation. this was not only causing corrosion, mildew, and mold growth in the mechanical rooms, but also causing mold dispersal throughout the school that was significant enough to cause sickness
to school personnel and students.

CONSEQUENCES OF CONDENSATION CONTROL FAILURE:
` Loss of Insulation Value
` Pipe Corrosions
` Unsafe Conditions
Insulation System Design
The Forgotten Technology that Saves Money & Energy for Schools
Main Considerations for Insulation Design
` Type of piping syst em
` Location of the system (inside, outside, washdown areas, etc.)
` Piping material (copper, steel, plastic)
` Jacketing needs
` Condensation control
` Personnel protection
` Customer’s budget

Types of Mechanical Insulation ` Fiberglass
` High Temp Mineral Wool
` Cellular Glass
` Closed Cell Rubber
` Polyisocyanurate
` Aerogel
Insulation Energy Audits
The Forgotten Technology that Saves Money & Energy for Schools
What is an insulation energy audit?Calculates the energy and dollars a facility or process is losing with its current insulation system and demonstrates how a more efficient system can:
` Save hundreds of thousands of Btus
` Increase building safety
` Improve the process control and efficiency
` Reduce fuel costs
` Contribute to a cleaner environment through the reduction of greenhouse gas emissions
The Forgotten Technology that Saves Money & Energy for Schools
Energy Audit Process?1. Meeting with facility personnel
2. Facility walkthrough
3. Custom calculations
4. Proposed insulation system
The Forgotten Technology that Saves Money & Energy for Schools
Energy Audit Example ` 8" NPS steel horizontal pipe
` 350°F process and 375° avg. ambient temp
` 8 MPH avg. wind speed
` Fuel: natural gas @ $10/mcf
` Insulation: mineral wool system with aluminum jacketing

Insulation Maintenance
The Forgotten Technology that Saves Money & Energy for Schools
Consequences of not maintaining insulation:
` Decrease in personnel safety
` Increased energy costs and emission of greenhouse gasses
` Overall building health declines
` Corrosion Under Insulation
` Condensation, ice, mold or mildew could develop
` Sustainability and/or ROI objectives may not be met
The Forgotten Technology that Saves Money & Energy for Schools
Signs of damaged mechanical insulation:
` Damage to protective jacketing
` Missing sections of insulation
` Failing supports
` Ice, mold, condensation, mildew or discoloration on the system
` “Fish mouthing,” sagging or pulling away of the system
` Joints in the insulation appear to be opening; expansion or contraction joints appear to not be functioning correctly
` “Hot spots” are occurring in the system
