MVHR and building physics knowledge for a healthy, comfortable and energy efficient home
As much as 25% of the heat loss of a building is via air leakages in the building fabric (ie, draughts). The airtightness of the building fabric is therefore an important metric to measure and improve as much as possible when building or renovating a home. Equally, a more airtight building also improves comfort, acoustics … Read more
If you’re researching installing a Mechanical Ventilation with Heat Recovery (MVHR) system for your project, you may have heard of an Enthalpy heat exchanger or ERV (Energy Recovery Ventilation). But what is an “Enthalpy” heat exchanger? How does it change humidity in the home? And is it expensive to install? The basics of enthalpy heat … Read more
If you’ve ever seen black mould in your home, you’re not alone. The problem with black mould is that unless it’s dealt with correctly (as I’ll explain below), it’s hazardous to health, not nice to look at – and will keep coming back.
