As you heat your home during the winter season, you will find the cost to do so is quite high. When you have to constantly provide warm comfort in the home, your heating system must use energy. A heating and cooling system both require energy to operate effectively and this unfortunately can cost you more money. Air conditioning heating and cooling systems such as central units can have a high operation cost if you do not know how to maintain your usage. Below are a few tips on how you can lower the cost of heating in your home but maintain the comfort you need during the winter season. (more…)

Cooking exhaust hoods designed for home kitchens vary widely in their ability to capture and vent away the air pollutants generated by the gas burners on cook stoves, according to a study by two Lawrence Berkeley National Laboratory (Berkeley Lab) scientists. Of seven representative devices they tested, the capture efficiency varied from less than 15 percent to more than 98 percent.

The study, by Woody Delp and Brett Singer of Berkeley Lab’s Environmental Energy Technologies Division, measured their pollutant capture efficiency, sound level generated by their fans, and airflow. Cooking exhaust hoods vent such pollutants as carbon monoxide, nitrogen oxides, formaldehyde, and fine particulates such as soot generated during cooking. (more…)
