Block Size and Estimating

Tammy,
please see this technical sheet;
RHINO BLOCK DATA SHEET

Hi Geoffrey,
 
How are you? I hope all is well there.
 
I have a couple of questions for you.
 
1. If I have a 500 sq ft house that has 2 rooms that are 10'x15' and one common area that people sit in. How many bricks
would I need for that, if the ceilings are 8' ceilings?
 
Can you give me a simply formula to figure out how many sq.ft a block will cover. or better yet, how many blocks do you need for 100 square feet, it will be easy for me to figure from there I think
 
Thanks,
Tammy

There are many ways to count blocks needed for a building. The wall area cannot be calculated from the floor area of a building. We need to know the total perimeter of the walls and the openings [doors and windows]. The place to start is a drawing or set of drawings. Rhino blocks [a more colorful name for ICEBs] are designed in metric, it’s easiest to do the drawings in meters or centimeters.
A 10’ x 15’ room might end up 3 meters [10 blocks] by 4.5 meters [15 blocks].
This is 150 sq ft, or 13.5 sq m
Having 2 rooms of 150 sqft leaves a 200 sqft area for a 500 sq ft house.
From the plan view [the view from the top] you can measure the length of the walls in meters and in blocks.
An 8’ foot high wall is about 2.4 meters.
Take the total perimeter of the walls [in blocks] and multiply it by the height [in blocks] then subtract out the openings [doors and windows].
