Use timers to determine when to take something out of the oven, instead of opening the oven door for repeated checks. Every time you open the oven door while something is cooking, the temperature drops up to 100 degrees and oven has to use additional energy to bring the temperature back up.
The voltage at the motor should be as close to the design limits, found on the nameplate, as possible. Changes of more than five% can lead to two to four% drops in efficiency and increase temperatures, which decrease the motor’s life. Voltage at the motor that is not within the design limits leads to a decrease in power factor. Low power factors may be penalized by your power company.
Use daylight to help light your interior spaces. Daylight can supplement artificial light. Smart lighting systems use occupancy, time of day and light sensors to control dimmable fixtures and coordinate with automated shade systems.such practices saves considerable amount of Electrical Energy.
