The Ranch Renovation EnerPHit Step 1
- EnerPHit • July 9, 2019
Recap of the first step of our step-by-step Passive House renovation project.
Comfort, or rather lack thereof in large parts of the house during wintertime, was the main driver to start with the first renovation measures. Here is a list with more details about the original comfort situation:
Cool and comfortable house in summertime
Cooling is hardly needed anytime, only in the addition, when it is very hot and the sun hits the sliding door glazing in the afternoon. We would manually ventilate the house in the early morning and at night by opening windows and patio doors.
Cold and very uncomfortable house in wintertime
Back of the house is especially cold during winter. This area includes bed- and bathrooms as well as 2 offices;
Bath towels don’t dry in winter;
Warm front house with running heater with cold spots along walls and leaky doors;
Walls and floors very cold in winter;
House does not warm up, even on sunny and warmer winter days it feels like a fridge.
No air flow in master bedroom
Room always felt uncomfortable but CO2 values are ok.
Had to sleep with open windows even during cold winter nights.
Here is a quick rundown of the relevant building assemblies and systems before I go into more detail about the measures of this first Passive House renovation step.
