Beauty is com­pat­i­ble with en­ergy ef­fi­ciency

The Covington News - - Showcase Of Homes -

Eye- pop­ping beauty for your home does not have to be sac­ri­ficed in honor of the en­vi­ron­ment.

Take a look at the award win­ning res­i­dence, Ea­gle Ris­ing, a project on 20 wilder­ness acres near Fort Collins, Colorado. Project man­agers re­port that the key chal­lenges on those windy, moun­tain­ous foothills were to limit the use of re­sources while achiev­ing de­sign grandeur, en­ergy ef­fi­ciency, sound re­sis­tance and com­fort.

“ The ap­pli­ca­tion of con­crete, not wood, is the an­swer to each one of those struc­tural re­quests,” said Todd Blyth of Nudura Cor­po­ra­tion. “ Home builders and com­mer­cial builders are on the lead­ing edge of this tech­nol­ogy.”

The Nudura form sys­tem con­sists of stay- in- place con­crete units, which de­liver su­pe­rior in­su­la­tion, Blyth ex­plained. “ The sys­tem is vastly su­pe­rior to the tra­di­tional stick fram­ing method. The in­ter­lock­ing units ( of re­in­forced con­crete sand­wiched be­tween two lay­ers of ex­panded polystyrene foam in­su­la­tion) pro­duce a home that is en­vi­ron­men­tally- friendly, but also with a foun­da­tion that is up to nine times stronger, with far more fire pro­tec­tion, far more sound in­su­la­tion and with the po­ten­tial to re­duce en­ergy costs up to 70 per­cent.”

Take a look at Ea­gle Ris­ing as an il­lus­tra­tion:

Ea­gle ris­ing res­i­dence

Win­ner: Best Cus­tom Home and Best Over­all Project in 2006, awarded by ICF Builder Mag­a­zine.

Project De­scrip­tion: To build a 4,400 square- foot home with a com­bi­na­tion stone stucco fin­ish. The owner wanted an en­ergy ef­fi­cient house, with high ceil­ings and curv­ing walls. Sound re­sis­tance was also top pri­or­ity in this very windy lo­ca­tion.

En­ergy ef­fi­ciency: Su­pe­rior in­su­la­tion and sus­tain­able ma­te­ri­als were first pri­or­ity. Con­crete, which fills the core of the in­ter­lock­ing units, is ideal on the ex­posed site where winds can ex­ceed 161 km/ hr ( 100 mi/ hr). The Nudura sys­tem pro­vides the ideal com­bi­na­tion of Rvalue, mass, and zero air in­fil­tra­tion to max­i­mize the en­ergy ef­fi­ciency.

Sound Con­trol: Struc­turally, the house is far more stable than tra­di­tional wood fram­ing meth­ods and the con­crete foun­da­tion pro­vides an ex­cel­lent ther­mal sound bar­rier.

Beauty: The Ea­gle Ris­ing ar­chi­tect was able to in­cor­po­rate a house with high ceil­ings and many curv­ing walls.

Un­like con­ven­tional build­ing meth­ods of the past, the Nudura forms of­fer ver­sa­til­ity — and, there­fore, walls and ceil­ings can be made to curve.

Com­fort: The in­ter­lock­ing forms are also re­sis­tant to ther­mal bridg­ing, where out­side cold trav­els eas­ily through walls to cre­ate un­com­fort­able cold spots, drafts, and musti­ness. The form sys­tem is also re­sis­tant to mold.
