When you’re having a worship service, sometimes you need an Environmental Effect. For example, you plan to use real candles in a Christmas Eve service. If the HVAC system is running at that time, then it can make it challenging to keep the candles lit. One solution is to ask one of the ushers to turn off the HVAC system just before the candle lighting. That way, the fan won’t be blowing and the candles will stay lit. However, if it is cold outside, then you don’t want the heat to stay off too long. You need to time the HVAC’s cycle so it warms up just before the closing song. Then you can turn it off. After the song, you can turn it back on again. After everyone has gone home, then the HVAC can return to standby mode.

Environmental Effects can enhance the worship service. In concerts, they often use a haze effect to enhance the lighting effects. The beams are easier to see if there is some fog in the air. However, you need to be sure that the haze is not going to cause any problems for the congregation. Be sure to use hazing fluids that are non-allergenic.
