Building highly comfortable, healthy and energy efficient homes, that use small amount of energy and emit very little operational carbon is critical in addressing the climate crisis we currently face. Passivhaus is a proven standard that leads us into the approaches to achieve these comfortable, healthy and low operational energy buildings. It is available, accessible and feasible to build this way. Individual clients, like us, can do it with help from experienced professionals. Even as a homeowner, you can educate yourself to understand the principles and dive into your own Passivhaus project. Building to a Passivhaus standard is important, but certifying it to the standard is even more important as a quality control process. That ensures that quality and targets are achieved throughout the project and that in the end, you as a customer, get what you paid for.
