Certainly! Let's customize the example to a scenario where we're sizing an HVAC system for a cozy cabin in a mountainous region, taking into account the unique factors of this environment. Scenario: Sizing HVAC for a Mountain Cabin Factors to consider: Area: The cabin measures 800 square feet. Occupancy: The cabin typically accommodates four people. Heat gain from other sources: There's a wood stove that generates around 3000 watts of heat during operation. Insulation: The cabin has good insulation due to its construction with thick logs, reducing heat transfer. Climate: The cabin is located in a mountainous area with cold winters and mild summers. Desired temperature difference: The owner prefers a cozy 10°F temperature difference between indoor and outdoor temperatures. Calculation method: Example 1 1. Estimate heat gain: People: 4 people * 150 watts/person = 600 watts Other sources: Heat from the wood stove = 3000 watts 2. Total heat gain:
