Calculating Heat Loss
How do I verify the calculated heat loss?
There are a few options to do this. You will need the following:
1. Q = UA(dT)2. ACCA Manual J3. Others
5/29/2018 23
Q= UA(dT)
What exactly is this equation?... And why do we need to understand it?
5/29/2018 24
Q= UA(dT)
What exactly is this equation?... And why do we need to understand it?
• Q = what we are trying to define
5/29/2018 25
Q= UA(dT)
What exactly is this equation?... And why do we need to understand it?
• Q = what we are trying to define
• U = the U-factor of the assembly
5/29/2018 26
Q= UA(dT)
• What exactly is this equation?... And why do we need to understand it?
• Q = what we are trying to define
• U = the U-factor of the assembly
• A = the Area of the assembly
5/29/2018 27
Q= UA(dT)
What exactly is this equation?... And why do we need to understand it?
• Q = what we are trying to define
• U = the U-factor of the assembly
• A = the Area of the assembly
• (dT) = Delta T or temperature difference
5/29/2018 28
Practice Example
Let’s calculate a simple heat loss of a wall• Here is a simple example of a heat loss calculation for one wall, and then the
same wall just adding one window.
5/29/2018 29
Practice Example
Let’s calculate a simple heat loss of a wall• Here is a simple example of a heat loss calculation for one wall, and then the
same wall just adding one window.
• Note the changes in heat loss when we add the window
5/29/2018 30
Practice Example
Q = UA(dT) = heat load assessment = defines equipment sizing.
• Ex. Room is 10 x 10 x 10
• Using Assuming a wall U=0.050• (Conversion) R-20 = (1 divided by 20) = U
5/29/2018 31
Lets look at just one wall
5/29/2018 32
Lets look at just one wall
• 1 Wall that is 10’ tall and 10’ wide. Equals an Area (A) of 100 Sq. Ft
5/29/2018 33
Lets look at just one wall
• 1 Wall that is 10’ tall and 10’ wide. Equals an Area (A) of 100 Sq. Ft
• Btu’s per hour (Q) = 0.050 (U) x 100 Sq Ft. (A) x 90 (dT)
5/29/2018 34
Lets look at just one wall
• 1 Wall that is 10’ tall and 10’ wide. Equals an Area (A) of 100 Sq. Ft
• Btu’s per hour (Q) = 0.0526 (U) x 100 Sq Ft. (A) x 90 (dT)
• Btu’s per wall for design loads = 450 Btu’s
5/29/2018 35
What is the total heat loss for all 4 walls of our Building?
Adding in all 4 walls at the exact same Btu’s for each wall (4 x 450) would require a heating appliance capable of supplying a minimum of 1,800 Btu’s
5/29/2018 36
What is the total heat loss for all 4 walls when we add a 4x4 Window meeting todays Energy Code into one wall?
Wall #4 was 100 Sq. Ft. at .0526 U- Factor. Now it is only 84 Sq. Ft. at the .050 U-Factor + 16 Square foot at a 0.32 U-Factor to accommodate the window
5/29/2018 37
Change Wall #4 and add a Window
• Wall 1 = .050 x 100 x 90 = 450 Btu’s
• Wall 2 = .050 x 100 x 90 = 450 Btu’s This can make a big Overall Difference
• Wall 3 = .050 x 100 x 90 = 450 Btu’s
• Wall 4 = .050x 84 x 90 = 378 Btu’s
• Window 1 In wall 4=
.32 x 16 x 90 = 461 Btu’s
Total Btu’s now are 2189 total Btu’s
-1800 Wall w/out Window
Difference of 389 Btu’s (It Adds Up)
5/29/2018 38
Class Practice Exercise #1(Go to the Plan at the end of Tab 6 in your 3 ring binder)
Look at only the Master Bedroom 2 walls and tell me what is the heat loss through them combined.
5/29/2018 39
Class Practice Exercise #1
Look at only the Master Bedroom 2 walls and tell me what is the heat loss through them combined
Remember the equation Q = UA (dT)
Given R value of 21 in the walls with a 8’ ceiling height
Don’t count the window areas in your calculation for walls- do them separately
What is the total heat loss of the two walls only? And windows only?
5/29/2018 40
Answers to Practice Exercise #1Wall #1 Window #1
14.5 x 5.25 x
8 4.5
116 Sq. Ft. (-) 23.625 (24) = 92 Sq. Ft.
Wall #2 Window #2 197 Sq. Ft. (Wall area only)
14.25 x 6 x
8___ 1.5___
114 Sq. Ft. (-) 9 Sq. Ft. = 105 Sq. Ft.
Walls only: Q = (U) .0476 x (A) 197 x (dT) 90 = 843.94 or 844 Btu’s of heat loss through these two walls only.
5/29/2018 41
Answers to Practice Exercise #1
Window #1 Window #2
5.25 x 6.00 x
4.5 1.5
23.625 (24) + 9.00 = 33.0 Total Sq. Ft Window Area
Assuming a 0.32 Window U Factor
Windows Only: Q = (U) 0.32 x (A) 33 x (dT) 90 = 950.04 or 951 Btu’s of heat loss through these two windows.
5/29/2018 42
Final Answers to Practice Exercise #1
Walls only: Q = (U) .0476 x (A) 197 x (dT) 90 = 843.94 or 844 Btu’s of heat loss through these two walls only.
+
Windows Only: Q = (U) 0.32 x (A) 33 x (dT) 90 = 950.04 or 951 Btu’s of heat loss through these two windows.
Equals a total Heat loss for only the two walls in the master bedroom of 1795 Btu’s
5/29/2018 43
Number 2
5/29/2018 44
Classroom Practice Exercise
Class Practice Exercise #2
This time Look at the Basement Floor, (Remember the equation Q = UA (dT))
The Following are the given.
-R value of 2 for the basement floor
-A under slab ground temperature of 55 degrees
- an interior design temperature of 70 degrees
What is the total heat loss of the floor only?
5/29/2018 45
Answer to Practice Exercise #2
Floor area #1 Floor Area #2
66 x 14 x
30 8
1980 Sq. Ft. + 112 Sq. Ft. = Total of 2092 Sq. Ft.
Q = (u) .50 x (A) 2092 x (dT) 15 = 15,690 Btu’s of heat loss through the Basement floor area.
5/29/2018 46
So… How do I verify the equipment is sized correctly?
5/29/2018 47
Equipment Sizing--There are a few Options
R 403.6 - Equipment SizingACCA Manual ‘J’, Manual ‘S’
Residential heating and cooling equipment will be sized in accordance with ACCA Manual S based on building loads calculated in accordance with ACCA Manual J…
5/29/2018 48
R 403.6 - Equipment SizingACCA Manual ‘J’, Manual ‘S’
Manual J guides HVAC designers to use ACCA Manual S to select equipment that is the right size.
Manual S sets equipment sizing limits, as summarized in Table 1.
5/29/2018 49
ACCA Manual S= Sizing of Equipment
5/29/2018 50
How do I verify the mechanical ventilation requirements of the code?
5/29/2018 51
Ventilation
See Energy code Section R403.5 (Pg. 50-53)
5/29/2018 52
Balanced Mechanical Ventilation
1322.202 (Pg. Definition of Mechanical Ventilation
5/29/2018 53
Mechanical Ventilation is the mechanical process of supplying conditioned or unconditioned air to, or
removing it from, any space.
How much and what type of ventilation is required?

• Total ventilation rate:
• Shall provide sufficient outdoor air = total ventilation rate average, for each one hour period in accordance with Table R403.5.2 .
• Continuous Ventilation:• A minimum of 50% of the total ventilation rate, but not less than 40 CFM, on a
continuous rate average for each one hour period in accordance with Table R403.5.2 or Equation 403.5.2

What do I look for when doing inspections?

Inspection Time
Foundations
• Foundation waterproofing is required from finished grade to top of footing.
IECC Section 402.1.1
Waterproofing and insulation systems may include a requirements for a Slip Sheet.IECC Section R402.1.1.3

Foundations
Waterproofing and insulation systems may include a requirements for a Slip Sheet.
Draining Insulation: Thermal insulation that, when installed, allows bulk water to drain by gravity from every point across its width.
Non-Draining Insulation: Thermal insulation that, when installed, allows bulk water to drain by gravity only on its vertical exterior surfaces.
