More and more, we’re hearing about sustainable, energy efficient practices, commonly known as green building. Successful building design and operational success is measured mostly by energy efficiency. One the key benchmarks that defines optimal performance is control of thermal energy flow and moisture. Adding EIFS wall assemblies with drainage to your home or building will do just that. And save you money in the meantime.
In a study conducted by the Oak Ridge National Laboratory (ORNL), it has come to be known that EIFS outperforms other typical exterior finishes like brick (which had the lowest thermal and moisture performance) or stone during the year. This means that no matter the weather, if it’s hot and humid or -40 degrees celcius, EIFS is an excellent solution to achieving ideal building performance. In order to achieve ideal building performance, movement of energy across a wall system should remain at around a value of zero. The same applies for the relative humidity within the wall system.
What does this mean?!
If both of these numbers are close to zero, the less your HVAC system needs to work, the more money you save.
Essentially, was EIFS does is create a perfect balance between indoor and outdoor conditions.
When there’s an imbalance, for example, in the summer, too much heat entering your home or building will require a higher cooling load. In the winter, too much heat leaving will increase the heating load. All this is saying is, at the end of the month, an imbalance will only have you paying more to your energy provider.
A balanced system will save you money on your energy bills.
Take this into consideration; The chart below demonstrates how much you can SAVE EACH YEAR if you reduce your heating costs by 35% which can definitely be achieved by using EIFS on your exterior walls.
With today’s energy costs rising, imagine what these numbers will be in 5 years from now. Using exterior foam insulation can offer a significant energy cost savings.
The ORNL study concluded that insulation is more beneficial when placed toward the exterior. This can be especially useful when thinking of re-modeling the exterior of an older building or home.
Think of how expensive it would be to tear down all your interior walls and re-insulate each room. And again, think of how expensive it is to keep warm in the winter and cool in the summer if you kept it as is.
Of course, all this only applies when properly applied by a qualified and reputable contractor. An improperly installed wall or use of sub-standard materials can contribute to negative effects.
