Re: TAC Input: ASHRAE 90.1 – 2010 8.4.2 – Research Topic

Mo-

ASHRAE 90.1 – 2010 8.4.2 requires automatic receptacle control in certain areas. This is very costly to implement. If nothing is plugged into the controlled receptacles, there are no energy savings or if minimal loads are left plugged in, there may be insignificant energy reductions. Since this is now being enforced in Florida, and may be expanded during the next code cycle, I would like to know:

Ø What are the installation costs of implementing the automatic control as outlined in a. b. and c. in 8.4.2

Ø What are the engineering costs

Ø What method is most frequently employed to comply

Ø What are the loads that are actually being controlled in office areas

Ø How much energy is being saved

Ø How much money is being saved considering time of day and utility rate schedules

Ø What are the unintended consequences of controlled receptacles

o Extension cords

o Circuit overload/imbalance

o Unnecessary outlets being added to spaces

o Damage to equipment plugged in

o Loss of food

o Loss of data

o Loss of productivity

Since this is not a life safety issue, only an energy saving measure, what is the:

Ø Net energy savings when considering materials, labor, etc.

Ø Return on investment based on any savings including utility costs

Ø Any other net benefits of controlling these receptacles

Soon there will be many actual installations that can be studied.

I would request TAC input to refine this proposal for a research project
