Lessons learned |
|
|
Initiative |
We have considered in the past few years mainly the issue of energy efficiency. The direct use of solar energy for our high heat demand was the logical next step
|
|
Integration methodology |
|
|
Crucial Interfaces |
The payback period is relatively long. As a family we are used to think in long terms. In this case, the "green arguments" were simply convincing.
