Oregon-based Ideabox, the company behind Aktiv with IKEA Portland, recently shared news of an expanded endeavor called Minibox. Minibox is actually a series of “minihomes” built to RV and park model codes. The tiny-house series has designs ranging from a 200 square-foot studio to a 320 square-foot one-bedroom/one-bath cottage. And you can bet Ideabox will continue to plug all the green stuff inside. Pricing for the non-wheel version starts at $42,500.
Looks like wood-fiber insulation board is coming to the USA, according to a Greenbuild update on Green Building Advisor. Agepan THD is the name of the product and it’s used as exterior sheathing for walls and roofs. Agepan boards connect in tongue and groove fashion and insulate to R-5.74 per panel (2″ x 74.5″ x 23-5/8″). The material has a high permeability (18 U.S. perms) and can be used in a wall assembly to dry to the exterior. It’s offered through Washington-based The Small Planet Workshop Store.

Concrete is everywhere in construction, so I like to note what’s happening to make concrete “greener.” CarbonCure Technologies, Inc. licenses technology in North America to make, for example, carbon-absorbed concrete blocks and other precast products. Basically, CO2 is injected during curing — making limestone — with the end result being a stronger, greener masonry and other precast products.
I noticed in Dwell‘s Prefab edition that one prefab was partially built with an innovative concrete masonry unit (CMU) by Nevada-based Omni Block. Omni Block is a structural CMU filled with Expanded Polystyrene inserts. Walls with Omni Block can be finished or, in the case of the Simpatico project (see below), left exposed for a modern interior or exterior. The manufacturer says the material is fire resistant, durable, and thermally efficient, and the blocks come in colors or with special aggregates.
