This is a commercial place and the nite time employee's are opening the doors/windows but keeping the air conditioners on. Does this increase our costs or does it just allow fresh air to circulate with the air that is being cooled inside by the conditioners. The doors and windows are only on 1 side of the building..The air conditioners are up too high for the staff to deal with. Any suggestions?

It depends on how the units are set up to operate. Opening the doors and windows will allow fresh air in but if the humidity is high outside it can cost more for the ac to remove that moisture. For most commercial rooftop units there are accessories called economizers to bring in fresh air. They check the humidity before they allow air in.

If the thermostat is not satisfied, i.e. outside air that is coming in is hotter than the thermostat setting then the compressors will run continually. If this is a commercial establishment then the fans probably run all the time. The control or thermostat circuit could be set up with a switch that when you turn on switch only the fans run and not the compressors and then have the doors open.
One concern that I see that in alot of commercial / industrial settings one of the major duties that is performed by the air conditioning is the removal of the humidity. This is an important part of "Feeling" comfortable and as important the removal of humidity and keeping the air cool greatly increases the life of electronics. In control rooms the main purpose is keeping the air dry and cool to help dissipate the heat from the electronics. Heat is the leading factor in the life span of electrical equipment.
Hope this helps

They are just defeating the whole point of air conditioning. It's sort of like trying to run up a down escalator - you're wasting a lot of energy for no purpose.
Some people just don't like air conditioning or don't understand it. My wife is that way. She always turns off the A/C and throws open the windows and acts like a dog riding in a car; she almost needs her face hanging out a window.
The night employees should be told that if they open the windows the air conditioning has to be turned off. Your electric bill is going to be nuts.

Of course it will increase the cost. That chilled air is going outside after you paid for it.
The A/C already mixes fresh air into the air it chills so it doesn't need new hot and muggy air from those windows.
You will save money if you have an electrician come in and add an on-off switch at easy-to-reach height that the staff could use to shut off the A/Cs if they want to open the windows.

The cold air falls out of the doors and is replaced by hot air from outside. This in turn is cooled and falls out of the doors. In effect you are trying to cool the neighbourhood and your electricity bills will reflect this. Can't you put the A/C on a timer so that it switches off in the period employees are leaving?

well i guess it depends wats going on what the weather is like outside but yea it would increse cost because a airconditior it just like a dehumidifier it takes the moisture out of the building to make it cooler and blowes cold air back in so if the humidity level outside is more than in the building than it would be pointless to run the air conditioner then.

Yes it will increase your bill. Mainly because you are letting in a lot of humidity. Humidity is a huge load on your air conditioner. It's called a latent heat load. I don't recommend opening the doors and windows.

are they swamp coolers and do they have return air or fresh air?
if they draw air from outside then a vent near where you want cool does not hurt you need to find the out put of the coolers and not have a hole bigger than about 75% of the out put or the air will come back in not out you should consult hvac contractor and have them check it out out side vent is ok if that is the way the system is designed but wont work good if you system has return air that may be able to be switched

That is a big no no. It can cause ice to form on your units. The units probably never turn off the whole time they are there.
Find out why they are doing this. If it is a good reason, find a way for the day crew to turn off the units before they leave for the night.
By the way, what will they do for the winter months.

Tha t would mean the air con units are trying to cool the whole of the area you're located in. Your power bill is going to be enormous.
