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.
