DWELLING ATTRIBUTES
- Floor Area less than 500sqm
- Standard concrete strip foundation
- No in-floor heating
FLOORS:
- Insulation to be installed around vertical edge of perimeter
- 300mm under finished ground level
- R-value to be 1,0 or more
- as per SANS 204-4.3.2
-by specialist
- No insulation installed under slab
ESTIMATED ENERGY CONSUMPTION
ELECTRICAL INSTALLATION ENDORSED BY SPECIALIST
EXISTING Low Voltage internal/external Light fitting - 14 Watt
NEW Low Voltage internal internal/external Light fitting - 14 Watt
Fluorescent light fitting (2 globes) - 36 Watt
SUBTOTAL: 534 Watt
Estimate Maximum Energy Demand as per SANS10420.
5 W/m² x 424m² = 2120W
Estimate Maximum Annual Energy Demand as per
SANS 10420.
5 W/m².a x 424m² = 2120W (a = 1 year)
Estimate Maximum Annual Energy Consumption:
Assume lights are on from 18:00 - 22:00 each day per year
(4h/day)
52 weeks x 7 days x 4 hours = 1456 hours/year
Lights = 534W or 0,534kW
0,534kW x 1456h.a = 777,5kWh.a
(less than 2120kWh.a)

NOTE: The use of other light fittings permitted as per owner's approval on condition
that the Watt usage per light fitting does not change.
CONCLUSION: THE DESIGN COMPLIES WITH THE REQUIREMENT OF SANS
10400-XA:2011 FOR ENERGY CONSUMPTION.
ROOF ASSEMBLY THERMAL RESISTIVILY:
METAL ROOF SHEETING
ROOF TO BE ENDORSED BY ENGINEER
According to SANS10400-XA and SANS204 to min. thermal resistivity value is as follows:
To achieve the resistivity of 3,7one of the following is recommended.
Think Pink Aerolite thermal and acoustic ceiling insulation with a min. thickness of 135mm which has an R-value of 3,38.
CONCLUSION:
THE DESIGN COMPLIES WITH SANS 10400-ZA:20011 IF THE ABOVE CONDITION IS MET.
