Barriers to ConservationBarriers to Conservation

Facility culture Past cheap energy Production mindset for creating revenue Maintenance budget constraints Resistance to change In the box thinking “We have always done it this

way”


Low Hanging Fruit OpportunitiesLow Hanging Fruit Opportunities

Systems operating when not adding value Lighting use (CFL’s, time clocks, occupancy sensors) Temperature set points and set backs not to

recommended standards Programmable thermostats or energy management

systems Replace aerators (faucet spray adapters) Compressed air pressure reduction Commission or tune systems Vending machine controls


Typical Justifiable OpportunitiesTypical Justifiable Opportunities

AdsilTM coating on condensers Light fixture retrofit (T12-T8-T5, CFL, LED) Variable speed drives Replace old motors with premium efficiency motors Replace old air conditioning equipment, boilers, or

chillers with new premium efficiency equipment Process part present switches Modular system sequencing Replace plumbing fixtures and flush valves Temperature reset based on outdoor air


Renewable Energy RoleRenewable Energy Role

Example of Innovative Solutions for Example of Innovative Solutions for Condenser CoilsCondenser CoilsExample of Innovative Solutions for Example of Innovative Solutions for Condenser CoilsCondenser Coils

ADSIL (www.adsil.com) Patented cleaning/coating process improves efficiency

of system by 12% in inland applications

Chemically bonds with aluminum fins and prevents oxidation, preventing efficiency losses

Does not support mold growth (when sprayed on evaporator coils, fan, and housing)

Improves flow over condenser, evaporator, and improves heat transfer efficiency

MACTEC developed EER grading tool for USEPA

MACTEC was chosen by USEPA to study and verify effects in hot/humid climate

MACTEC has identified more than $77 million in energy savings


Lowers emissions, water use, and discharge

Low hanging fruit opportunities with little or no capital outlay

Saves valuable resources for future generations

Saves capital costs

Reduces operating costs

Global warming or not, it is the right thing to do!
