Thermal bypasses are the reason many deep retrofits fail to deliver predicted energy savings. A building can have R-40 walls, triple-glazed windows, a...
When you seal up a building envelope with high-R insulation, thermal bridges become the dominant path for heat loss. Adding a blackwater heat exchange...
Why This Topic Matters Now Deep-retrofit projects that aim for net-zero energy often stop at the building envelope. The logic is straightforward: tigh...
For retrofit engineers working on cold-climate blackwater digesters, the question is not whether to phase-separate, but how far to push hydraulic rete...
Introduction: The R-Value Mismatch in Dynamic SystemsFor decades, the building science community has relied on the R-value as the primary metric for i...
A deep-envelope retrofit tightens the building shell, adds continuous insulation, and manages vapour diffusion. A greywater heat recovery (GWHR) syste...
