Room Basics Step 1 of 3

Your preferred units:

Metric

Imperial

Room name:

Type of room:

{{room.name}}

Dimensions Step 2 of 3

Height ({{ctrl.getUnitLabel('length', ctrl.selected_units)}})

Width ({{ctrl.getUnitLabel('length',ctrl.selected_units)}})

Length ({{ctrl.getUnitLabel('length', ctrl.selected_units)}})

Number of external walls

Total area of windows (sq. {{ctrl.getUnitLabel('length', ctrl.selected_units)}}.)

Measure the area of a window by multiplying the width by the height in {{ctrl.getUnitLabel('length', ctrl.selected_units)}}. Use the sum of all windows if there are more than one.

Construction Materials Step 3 of 3

Result: {{ctrl.calc.watts}} Watts ({{ctrl.calc.btus}} BTUs)

{{ctrl.calc.name !='' ? ctrl.calc.name : ctrl.calc.room_type_name}} requires approximately {{ctrl.calc.watts}} Watts ({{ctrl.calc.btus}} BTUs) according to the parameters you’ve entered. This is a MARC-approved calculation and includes a 20 percent safety margin.
