A house  is made up of many different parts or components like windows, the roof or the heater. Collectively, these parts begin to define a house "system" and this system can perform efficiently or inefficiently. We are most concerned about how the house system performs thermally - how hot or cold will the house become as the outdoor temperature changes ?

A  House  "System"

There are  a number of parameters or variables that can be investigated to simulate how a house will perform thermally:

Our Thermal Simulations compare different designs known as "runs" and then quantitatively and graphically tracks the change in performance.

Design Analysis 

A summary sheet or "Run Comparison" is prepared that graphically represents the relative change in performance of the differnt design decisions. A number of performance metrics are used.

A "Detail Sheet" with all the specific run data is created for each design. The Details Sheet records all the relevant design decisions; graphs the 24-hour termperature and heat flow (Q) data, and tracks the changes in a critical set of  metrics.
