keidas Porvoo, Finland / 2023 / In collaboration with Cindy He
rhino, enscape, photoshop, illustrator

Located in Porvoo, Finland, Keidas is an entirely self-sufficient residence contributing low embodied carbon levels and redefining building systems. Direct sunlight from the summer and winter solstice contributes additional passive heating into the most used programs, such as the living room. Because of Porvoo’s geothermally-potent geography, heating is primarily drawn from underground using copper pipes before distributing through the HVAC systems and radiant heat pipes underneath the floorboards. Electricity is harvested using the photovoltaic panels on the south-sloped roof facade, stored in a portable battery and distributed along the inner walls of the service voids. Rainwater collected using the sloped rain gutter into the outdoor insulated cistern passes through the greywater system before accumulating in the potable water tank while disturbing excess water into the rain garden. Any accumulated blackwater is disposed of using the composting toilets or passed through the Waterloo biofilters and returned to the environment. A double-stud structure system, cellulose insulation, and extruded polystyrene insulation ensures maximum insulation.
