Greenleaf House, Evanston, Illinois, uses SIPS panels, which made construction quicker and ended in a project with a higher R-value and lower air infiltration. The use of SIPS also made it possible to downsize the mechanical systems and made it so that there was less construction waste. The panels have foam splines, instead of timber splines, ending up in less bridging through the wall. The windows and eaves incorporate passive solar heating and shading.
The mechanical systems for the house include high efficiency boiler for the heating. Heating is done through in-slab hydronic radiant heat with R-64 insulation. Cooling is through a mini-split system allowing rooms to receive cooling independently. Air ventilation is through a heat recovery ventilator.
Concrete utilizes 30% fly ash. The siding is shou suji-ban which was salvaged from one of the clients large scale sculptures. Other siding is galvalume (recyclable with a high recycled post-consumer content)
This home is a new construction single family residence on a rare, unbuilt lot in Evanston, IL. The lot was a mushroom farm 100 years ago, and the house is viewed as a modern-day farmhouse. The rear structure is a sculpture studio for the owner who is a working sculptor and professor.
The exterior of the house incorporates shou sugi-ban charred cedar siding that was salvaged from the client's large scale sculpture in Saint Louis. The balance of the the exterior skin is combinations of industrial metal panels with the emphasis being on an honest expression of the materiality of the components.
The structure of the house is SIPS panels providing a fast, tight envelope with a high R-value. The house is on a burnished concrete slab with in-floor radiant heat.
