Environmental Advantages of ICF Vs Wood Construction
The country and the world are going through a reassessment of values, and nowhere does this show up as much in home construction. Big, garish houses with two-story foyers, family rooms with vaulted ceilings, and walk-in closets the size of a room, are starting to be viewed as self-indulgent excesses. The name of the game now is energy efficiency, insulated concrete form (ICF structures), and the conservation of natural resources. Consider that a typical 2 thousand square foot house requires felling over a hundred trees to build; and a 4 thousand square foot house requires felling over two hundred trees. arti mimpi
Moreover, it is estimated that about 1/6 of the wood used in construction is wasted and winds up in landfills. The Environmental Protection Agency estimates that construction of a 2 thousand square foot house generates 1.7 tons of wood waste. Besides the sheer waste, some of the environmental risks from dumping engineered wood products include contamination of surface water, negative effects on plant growth, and changes in the chemistry and biology of underlying soils. The average cost to the builder (which of course is passed along to the homeowner) of disposing of construction waste is over $500 per house.
