1. What is MCS Room by Room Heat Loss Calculator?

Definition: This calculator estimates the total heat loss (Q) for individual rooms according to MCS standards by summing fabric and ventilation heat losses.

Purpose: It helps heating engineers and energy assessors determine the heating requirements for each room in a building.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Total heat loss (Watts)
• Fabric — Heat loss through building fabric (W)
• Ventilation — Heat loss through air changes (W)

Explanation: The fabric and ventilation components are calculated separately according to MCS standards and then summed to give the total heat loss for each room.

3. Importance of Room-by-Room Heat Loss Calculation

Details: Accurate heat loss calculations ensure properly sized heating systems, energy efficiency, and compliance with MCS standards for renewable heating installations.

4. Using the Calculator

Tips: Enter the fabric heat loss and ventilation heat loss values in Watts. Both values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: What is fabric heat loss?
A: Heat lost through walls, floors, roofs, windows and doors, calculated using U-values and temperature differences.

Q2: What is ventilation heat loss?
A: Heat lost through air changes in the room, calculated using air change rates, volume, and temperature differences.

Q3: Why calculate room by room?
A: MCS requires room-by-room calculations to ensure proper heat distribution and system design, especially for heat pumps.

Q4: Where do I get the input values?
A: Use our separate Fabric Heat Loss and Ventilation Heat Loss calculators, or input values from your heat loss software.

Q5: Does this include design margins?
A: No, consider adding appropriate design margins based on system type and building characteristics.
