Energy-efficient Quieter Resistant moisture, mold, and the elements. to fire, What is a Performance Building? A high-performance residential or commercial building is a building with en- ergy, economic, and environmental performance that is substantially better than standard practice. Its energy efficient, so it saves money and natural resources. Its a healthy place to live and work for its occupants and has relatively low impact on the environment. The benefits that these perform- ance structures offer are: • Better Comfort • Healthier Indoor Air • Longer Durability • Lower Energy Bills • Increase in Real-Estate Market Value A Case for Change Soaring utility costs have taken hold across the country generating new consumer demand for energy-saving homes. The primary goal of U.S. Department of Energy (DOE)s “Building America” program is to help develop energy solutions for new and existing homes and encourage builders to incorporate these features as part of their standard construction packages. Building a high-performance, energy-efficient home that is green is the most important and profitable hedge we have against an energy crisis, while meeting concerns for the environment. It is also one of the most substantive ways a builder can differentiate themselves from the competition and a buyer can increase the “affordability” of their home through lower ownership costs. The bottom line is that high-performance green buildings are good for the environment, have better indoor air quality, less mainte- nance, excellent resale value, and theyre built to last.INTEGRATED SYSTEMS BUILDING SOLUTIONS COMMERCIAL INDUSTRIAL RESIDENTIAL Greenpositive ecological impact.

A Better Way to Build SmarterUltra-Efficient, High-Performance Green Demo Home ProposedAs homeowners in Chicago’s Metropolitan area brace for significant energy rate hikes thissummer, the U.S. Department of Energys Building America program has partnered withthe Illinois Dept. of Energy, the NAHB Research Center, and local high-performancegreen builder, Crossbridge Builders, to introduce an energy-saving demonstration home tohelp ease the impact of rising energy costs. The Ultra-Efficient, High-Performance GreenHome is to be located in Chicago’s North Shore community of Chicago.Construction of the 3,966-square-foot home is projected to be completed in Spring of2009. The house will feature products, systems, and design techniques that facilitate dra-matic improvements in energy performance and lower utility bills for homeowners. Theexterior of the two-story house will have a stone, brick and stucco facade and two-car ga-rage and blends with the traditional architecture of this well established community. But atthe building’s shell & core, and interior, the advanced high-performance, energy-savingimprovements abound.Using a systems approach, enhancements will be made throughout the entire home—building envelope, space conditioning systems, solar thermal package, photovoltaics, wa-ter heating, lighting, and appliances. Some of the homes less visible features will help toprovide greater occupant comfort, better indoor air quality, enhanced durability, and lowermaintenance.Insulated Concrete Forms (ICF) provides for an air-tight concrete exterior structure. Struc-tural Insulated Panels (SIP) is used for the roof sheathing. Paired with high-efficiency win-dows, this system provides for a high-performance building that is stronger, quieter, andbetter for our environment. Solar collectors hug two sides of the roof. One set of panelspreheats the homes hot water before the temperature is boosted by a small tank lessheater located in the basement; the other set of panels comprises the photovoltaic (PV)system which generates electricity that can be used in the home or fed back to the utilitywhen excess power is produced.Inside, a structural steel panelized framing system made of recycled steel is utilized forfloor trusses, interior walls, and roof structure. The ICF’s provide an outstanding R-22 rat-ing with its 2¼ inch expanded polystyrene (EPS) insulation material on both sides of theexterior wall assembly. In conjunction with the SIP’s roof panels, recycled paper fiber insu-lation is blown into the attic which significantly reduces heat loss transmission to and fromthe outside; achieving an incredible R-50. These whole-house integrated systems allowfor up to 40% HVAC size reductions.While not rated as a "zero energy home," the Ultra-Efficient Home is expected to use lessthan half the energy of a standard, code-compliant home of similar size in the area. TheNAHB Research Center estimates the homes upgrades should lower utility bills by morethan $160 a month, even without calculating the anticipated savings from the PV system.This demonstration home will be one of the most energy-efficient homes built under theBuilding America program. Not counting the photovoltaic system, the utility savings of thehouse are equal to or greater than the additional costs incurred for the upgrades whenamortized on a monthly basis and financed into the mortgage. These homes raise mort-gage qualifying ratios and provide buyers with greater purchasing power.One of the primary objectives of developing this home was to provide a comprehensiveblueprint for balancing the advanced technologies with reasonable first costs. The increas-ing availability of tax credit incentives for energy-efficient homes also helps to offset costs,and will potentially encourage further implementation of these market-ready technologies.
Energy-efficient Stronger The Thermal Envelope Greener for Future Building. Vision A "thermal envelope" is everything about the house that serves to shield the living space from the outdoors. It includes the wall and roof assemblies, insulation, win- dows, doors, finishes, weather-stripping, and air/vapor retarders. Our structures in- corporate advanced green building technologies such as: • ICF’s for Core and Shell • Recycled Structural Steel Floor Truss & Roof Assemblies • SIP’s Roof Panel Systems • High-Performance Windows & Doors • Controlled Heat Recovery Air Exchangers How much does it cost? There is a growing interest today on the part of commercial building owners, facilities man- agers, architects, engineers, and builders to design and construct the best possible building for the allotted budget. Depending on the aggressiveness of the design, experience has shown that it costs no more than 10% more to build high-performance buildings. Some high-performance buildings cost less to construct. Sometimes additional costs can be pro- cured using cost-benefits ratios and life-cycle costing. The added cost, if any, of system investment each year is compared to the cost of fuel saved each year. Total energy costs are, on average, about 50% less than those for conventionally designed buildings. In many cases, the right-sizing of mechanical systems through passive solar design offsets the costs for additional windows or controls. The bottom line is that although a high-performance home may cost a little more to build, they use less energy. Smaller utility bills offset slightly higher mortgage payments. Buyers receive the benefits while paying no more per month than they would in a conventional home. Rising energy prices boost the financial advantages of high-performance homes. Mortgage lenders recognize the financial benefit of a high-performance home by making “Energy-Efficient Mortgage” loans. How does a high-performance home meet the performance criteria? The underlying thread is called the “whole-house approach”. This means that the house is viewed as a system, in which the interactions between the many parts of the home are carefully considered during design and construction. Proper integration of a building’s envelope (the foundation, walls, windows, and roof) with its me- chanical systems (space and water heating, cooling, and ventilation) results in maximum energy savings. With high-performance building envelopes, builders can install smaller, less expensive heating, ventilating, and air- conditioning systems. These homes qualify for green building programs and are Energy Star™ compliant.INTEGRATED SYSTEMS BUILDING SOLUTIONS COMMERCIAL INDUSTRIAL RESIDENTIAL Greenpositive ecological impact. A
CrossBridge Builders is a Performance Builder.We offer a superior structural building system which delivers a high-performance structure and envelope for commercial and residentialapplications.ICFIt starts with an Insulating Concrete Form (ICF)Foundation. These super insulating forms employEPS (expanded polystyrene) panels that can formwalls of virtually any thickness, from 4” on up in2” increments. The space between the panels isfilled with concrete that cures and hardens into amonolithic, reinforced core of incredible strength.From the footing to the roofline, we can buildwalls with R-Values from R-22 to R-40 and arerated as Energy Star Homes by the Environ-mental Protection Agency. This qualifies some home buyers for theFHA’s Energy-Efficient Mortgage Program.™SteelWith a steel truss decking system which can spanup to 63, our structures can be engineered toeliminate most if not all red iron and columnsnormally required by conventional building meth-ods.
