Question

Using the degree day method calculate the annual kwh use in springfiled il with a heat loss of 12kwh an inddor twmperature of 7

Answer 1

The correct solution is "21024 KWh/degree day".

Step-by-step explanation:

The given query is incomplete. Below is the attachment of complete query is provided.

The given values are:

Indoor design temperature:

= 70°F

Now,

According to the question,

The heat loss annually will be:

=
`12* 24* 365`

=
`105120 \ KW`

Degree days will be:

=
`75-65`

=
`5`

Hence,

Annual KWh use will be:

=
`(Heat \ loss \ annually)/(degree \ days)`

On substituting the values, we get

=
`(105120)/(5)`

=
`21024 \ KWh/degree \ day`
