Certifications & Acknowledgments

April 16, 2010

Soon after the third-party performance testing was performed, all the required forms were submitted to the various agencies to review and approve our applications for certifications.  

  

Sponsored by the US Department of Energy, Builder’s Challenge recognizes exceptional attention to quality and energy performance. The program uses the EnergySmart Home scale to rate efficiency. To meet the challenge, a home must achieve a rating of 70 or lower, representing an improvement of 30% over a typical home. This home met the challenge on March 1st, 2010 with a rating of 55.  

  

The NAHB Green Building Program was initiated in 2005 by the National Association of Home Builders. The NAHB Green Building program is similar to LEED, but only applicable to residential construction. Green Building Program houses are awarded points within specific categories and can receive a rating of Bronze, Silver, Gold or Emerald. On March 24, 2010 this home was awarded a Gold rating from NAHB.  

  

The LEED for Homes® rating system is the nationally accepted benchmark for the design, construction and operation of high performance green buildings. LEED projects are awarded points within specific categories and can receive a rating of Certified, Silver, Gold or Platinum. We are proud to report that on April 6th, 2010 this home was awarded Gold certification.  It is the first home to achieve LEED certification in Wichita, Kansas.   

  

ENERGY STAR® was developed in 1992 by the U.S. Department of Energy (DOE) and the U.S. Environmental Protection Agency (EPA). Its mission is to promote clean and efficient energy technologies, enabling consumers to save money while protecting the environment. This home received the ENERGY STAR on April 8th, 2010.On Friday, April 9th, Teresa Burk, from the Wichita Committee of the USGBC Central Plains Chapter presented Adam Bauer with the LEED for Homes – Gold certificate.

Parade of Homes

March 25, 2010

While we participated in the Home Show, we decided to also participate in the Wichita Area Home Builders Association Spring Parade of Homes.

 

 

This years Parade of Homes is scheduled for April 10&11, 17&18, 24&25, with hours from Noon to 6:00 p.m. There will be 182 homes in price ranges from $100,000 to over 1.4 million and are located in Wichita and surrounding areas. Our home is listed as entry 41 in the Parade of Homes Magazine that can be viewed and downloaded from the Wichita Area Builders Association web site at www.wabahome.com.

By the opening day of the parade, we expect to have verification that we have in fact received LEED® for Homes – Gold certification, NAHB National Green Building Program – Gold certification, the ENERGY STAR® rating and the U.S. Department Of Energy’s – Builder’s Challenge award. 

No Indoor airPLUS

March 25, 2010

As the end of the construction process approaches, we began to look over each program we are attempting to qualify for. This process involved a detailed review of each program’s checklist and re-reading of the detailed explanations that accompany them. 

Each program has differing requirements for qualifying. LEED® for Homes has pre-requisites for various categories that must be achieved before any points can be attained in that category. The NAHB Green Building Program has a minimum number of points that are required to achieve a rating in each category and all categories must have the same rating to achieve that overall level of rating or certification. The ENERGY STAR® and Indoor airPLUS programs require that each item on their checklist be achieved in order to receive the rating, The Builder’s Challenge program is the least restrictive and has many items that are recommended as best practices but have exceptions based on local practices.  

Prior to starting construction on the house, each program checklist was used to develop specifications for each phase of the process. If an item on a checklist was unclear, we referred to the detailed explanation for clarification. Our initial reading of “Bituminous membrane installed at valleys & penetrations” which is item 1.9 in the Water-Managed Roof Assemblies on the Indoor airPLUS checklist, seemed to be satisfied by our standard practice of totally covering the entire roof of the house with UL 15# asphalt saturated felt and then installing metal flashings in the valleys. While conducting our review of this item, the term “self-sealing” was included in the detailed description. We considered reworking the roofing to comply, but decided not to because of cost and weather conditions. 

While we are still on track to quality for LEED for Homes – Gold certification, NAHB Green Building Program – Gold certification, ENERGY STAR, and the U.S. Department Of Energy’s – Builder’s Challenge programs, we regret the loss of not qualifying for the U.S Environmental Protection Agency’s – Indoor airPLUS rating.

Gutters & Downspouts

March 17, 2010

Controlling the rain water as it runs off the roof is a durability issue, addressed both by the NAHB Green Building Program and the U.S. Department of Energy’s – Builder’s Challenge program. Pre-finished gutters and downspouts are installed to capture and drain all the roof surfaces away from the house.

Raters, Inspections and Checklists

February 9, 2010

Independent third party verification is a key part of LEED® for Homes, ENERGY STAR®, NAHB National Green Building Program, the U.S Environmental Protection Agency’s – Indoor airPLUS, and the U.S. Department Of Energy’s – Builder’s Challenge programs. Inspectors or raters check the home for compliance with each program’s requirements.

ENERGY STAR® Thermal Bypass Inspection Checklist

Qualifying as an ENERGY STAR® home is a mandatory minimum level of energy performance required for LEED® for Homes. Completion of the Thermal Bypass Inspection Checklist is the first step of the qualification process.

At the same time the Thermal Bypass Inspection was being performed, so were the 1st inspections for LEED® for Homes, the NAHB National Green Building Program, and Indoor airPLUS.

Insulation

February 4, 2010

The process of insulating the house begins by sealing all holes and cracks where air leakage might occur. Air leakage can cause indoor air quality problems, condensation, excess energy use, and comfort complaints. Leakage from outdoors to indoors is known as infiltration and leakage from indoors to outdoors is known as exfiltration. 

Dow Great Stuff Pro™ Gaps & Cracks insulating foam sealant is sprayed around wiring from the attic through the top plate of an interior wall.

Holes in top plate that were drilled and then not used are filled the foam. This is done to eliminate air movement inside the wall cavity.

Holes in studs are filled the foam. This same foam is applied to wire openings in all electrical boxes.

The same is applied to the shim space around all windows and exterior doors.

The joint between the bottom plates of all exterior walls and the floor is caulked. This includes the basement walls as well.

The insulation system for the walls is Johns Mansville’s loose-fill fiber glass Spider Custom Blow-In-Blanket with an R value of 23. Since it is fiberglass it will not hold moisture, it will not support mold growth, it will not rot or decompose and is non-combustible. The system is formaldehyde-free, and contains no acidic fire retardant chemicals. 

Part of the insulation system is netting that is stabled to the studs on all the Main Level exterior walls. View of West Kitchen wall.

Netting installed on the South Living Room / Kitchen wall.

The rim joist space is enclosed with the netting in order to be filled the insulation.

Selected interior walls were netted on both sides and filled with insulation to reduce sound transmission from one room to another.

Insulation applied around the skylight tubes.

Air chutes are installed at all soffit vents to keep attic insulation from blocking the air circulation in the attic.

Batt insulation is installed in the vaulted ceiling above the Kitchen.

After the drywall is complete, the Attic is insulated with Johns Mansville Climate Pro/Attic Protector formaldehyde-free loose fill fiberglass insulation for an R value of 38.

In addition to the 1” Styrofoam that was applied to the basement walls prior to starting framing, the exterior basement walls are insulated with paper faced R13 fiberglass batts.

Upon completion of the insulation, another series of inspections are completed to assure compliance with the LEED® for Homes, ENERGY STAR®, NAHB Green Building, Indoor airPlus, and the Builders Challenge programs.

Inspections

December 28, 2009

Inspections are “third party” verifications that various phases of work are being performed in accordance with the required building codes and the requirements of the five programs that this home will be certified for. The first group of inspections was performed by the City of Wichita when the basement was being constructed. Those inspections checked that the house was correctly located on the lot and that the required reinforcing steel was installed in the basement footings and walls. These inspections were preformed on August 26th.

Before the insulation can be installed in the house, a second group of inspections is required by the City of Wichita. This series of inspections are to check the “rough-ins” of the HVAC, plumbing and electrical systems. These inspections were performed on November 13th and 16th. After the trades “rough-ins” are approved and signed off, the next required inspection is the framing. It was performed and approved on November 17th.

Signatures and dates on the City of Wichita inspection card. View of the backside of the card taped to the Kitchen window.

Upon completion of the insulation, another series of inspections will be required to assure compliance with the LEED® for Homes, ENERGY STAR®, NAHB Green Building, Indoor airPLUS, and the Builders Challenge programs.
