It will operate with a coefficient of performance (COP) >1:1 down to -25C (~-15F) and at -10C (~15F) it has a COPS >2:1; at freezing the COPs is around 3:1.  

What is the correlation coefficient?

Solar Heat Gain Coefficient (SHGC) measures solar energy absorbed into the building.

Lastly the Shading Coefficient, target around 0.30, again lower the better.  

Once you figure out the cap rate, if you price your purchase on that coefficient then all you are doing is trending with the market.

But before you can do that you have to accurately calculate the beta coefficient as well as a risk free return.

To reduce reverberation, which we measure with NRC (Noise Reduction Coefficient), you want to baffle and absorb sound that's bouncing around in a hollow cavity, like between the floor and ceiling.

Then you pay the costs of running this asset and you're left with $5,000 out of which you pay debt service (if there is debt) and put the rest in your pocket as cash flow.The reason Cap Rate is important is because if we invert the formula we are able to place a value on the asset using the estimated NOI and the known cap rate coefficient, just I did in the example above:If you are willing to buy a building which generates $5000 of NOI so lang as you can project 10% return (which in this case is the cap rate), then you'd value this acquisition at $50,000.

-Coefficient of Expansion and heat transfer, shade exterior concrete so it doesn’t transfer the heat or cold into the building pad.Road surface/footing requirements- rock or concrete/asphalt.

He will need to know insulation levels (walls, floor, ceiling/roof), square footages of exterior surfaces, number and orientation of windows (and their U-value and shading coefficients), what type of sealing is being done (to determine an approximate infiltration rate), overhangs etc.
