Karon EnerPHitEnerPHit: achieving the Passive House building standard with existing buildings. This is a current project which is a deep energy efficiency retrofit. What really makes this project stand above the rest is while during the project the structure needs to maintain its purpose as inhabitable. Some quick details: natural gas boiler/domestic hot water amended to electric heat pump, significant upgrade to triple pane tilt/turn windows, moving the stair well location across the house, structural changes to enhance the home to an open floor plan.
The best way to describe the project is by comparing it to open heart surgery where little anesthetic is used and the patient is awake during the procedure.
