Fahrenheit and Celcius

Temperature is an important factor in many areas of the Solar House. Air circulating throug a building can help maintain a comfortable temperature. When temperatures are too high or too low then some people can waste energy trying to maintain a comfortable temperature inside a building. It is important to take certain precautions in preventing energy waste in areas of

GRIDc collects temperature data from various areas of the house including upper and lower sunspace in addition to ambient, or outside, air temperature.

Access the data export on the www.gridc.net website. Gather data over an averaging period of a day on the various temperature inside and outside of the Solar House. Take the temperatures that are given in degrees Celcius and convert them to degress Fahrenheit. Use the above information if you have any questions on converting temperatures.

The British thermal Unit (BTU):

The British Thermal Unit (BTU) is a unit for energy. By definition, it is the amount of energy needed to increase the temperature of one pound of water by one degree Fahrenheit. This unit is commonly used heating, cooling, and steam generation.

1 BTU = 1055.05585 Joules

Example:  

How many joules are in 2 BTUs?

2 BTU * 1055.06 = 2110.12 J

How many BTUs are in 3000 J?

3000J / 1055.06 = 2.84 BTU
