AIBD Magazine - Winter 2017

AIBD President’s Message Kevin Holdridge is President of KDH Residential Designs in Charlotte, North Carolina. He is currently the President of the Charlotte Metro Chapter and the National President of the AIBD. He is also a member of the National Home Builders Association where Kevin received his Certified Green Professional as well as his Certified Aging in Place designations.

The

American Institute of Building Design is experiencing fantastic growth in membership and revenue, a testament to our new business model. The grass roots campaign of local chapters offering education and networking events on a monthly basis to our members is a great benefit to designers, architects and associate members alike. We see these chapters as local outreach ambassadors.

We need to continue our efforts for the chapters to create relationships with local building officials, home owners associations and the architectural review boards in their areas.

We are enjoying a new excitement around the only organization dedicated to the Residential Design profession. There are many programs, committees and task forces working in concert with one another on items from copyright infringement, education, certification, ANSI accreditation and public relations. We are continuing to seize opportunities in our ever changing industry by working with other great organizations like the NAHB, CEDIA, CIAT, TIBD and NKBA to only name a few.

We continue to see legislative threats to our industry, but we have strength in numbers. Once a threat is discovered on a local level, we have been able to rally the local chapters and our partner organizations in conjunction with AIBD council in order to present our case. So far we have been very successful, but I encourage everyone to recruit new members to keep our organization growing. We have strength in numbers and we need to bring in youthful members and mentor them into carrying on the profession as we have. I ask you to look back at the people that have influenced or nurtured your career over the years and become that influence for someone else. Mentorship in itself is a staple of our organization, promoting the success of our industry.

It is an honor leading this organization and I look forward to the future potential of the AIBD with the new certification possibilities and continued efforts to better our industry. We are the only national organization dedicated to the education and promotion of the residential design industry. In 2017 we are looking to build on our latest success and turn them into long term sustainable growth. Let’s not forget, this is OUR organization and together we can do great things.

AIBD Executive Director’s Message

Steve Mickley is the Executive Director of AIBD and a Certified Professional Building Designer. Steve holds numerous awards, such as AIBD’s President’s Award and AIBD Designer of the Year.

“Let

us not forget why we are here. It is for the advancement of our industry and those who strive to become our contemporaries.” My favorite quote was first written

by AIBD Past President Don Gore in a 1996 issue of the AIBD magazine. Those who have known me twenty years are also able to recite that quote. Thanks to the many times I’ve used Don’s words to “rally the troops.” In this case, my intent is to use them to express my pride for our organization and its premier awards program, the American Residential Design Awards, or ARDA. As an all-inclusive awards program, it has truly grown into a spectacular national affair.

AIBD’s mission is to enhance, develop, educate and promote the value of the residential design professional. ARDA exemplifies that mission. More so this year than ever before. The number of firms represented grew by nearly twenty-five percent and its reach is extending deeper into the industry. Unlike design competitions you’ll find throughout our industry, ARDA represents excellence in residential design by serving more as a confirmation than a contest. As a result, the quality of the work ARDA recognizes is magnificent.

All the credit is due to a hardworking group of members who have embodied the mission and worked tirelessly for the Institute – our ARDA Committee. Most importantly, I thank Michael Battaglia for his contributions. After twelve years as the ARDA Chairman, Mike has resigned and is taking on new challenges on behalf of our industry as the AIBD Director of Codes. Mike, I deeply appreciate all you’ve done. It has been a pleasure to work with someone with such vision and enthusiasm. I wish you the best and can’t wait to help you get started on your new projects.

Looking forward to next year, I welcome our new ARDA leader, Karen Kassik-Michelsohn.

Karen is an ARDA award winning designer, a recognized builder, and has served as the chairperson of the Best of American Living Awards, referred to as BALA. Through the years she has expertly marketed building design for her own business and for others. ARDA is lucky to have someone with her experience and skills working for to spotlight creative and innovated residential designers, builders, remodelers, architects, and interior designers.

As 2017 begins, AIBD continues to be “fishers of men (and women)” rather than just the “keeper of the aquarium.” It is committed to continuously growing its influence through education, certification and advocacy. I invite residential design and construction professionals to become a part of our mission. Whether it be as a member, a conference attendee, an email list subscriber, or a guest of one of our online educational sessions.

Everyone is eligible to enter the American Residential Design Awards.

WINTER 2016 - 02

Past ARDA Chair’s Message Michael Battaglia is a graduate of ITT Tech of Dayton with an Associate’s degree in Architectural Engineering. In 1990, he opened Michael J. Battaglia Residential Design, providing home design service to private clients and builders. Michael’s passion for residential design has been enhanced with interest in the development of the science of building.

The

American Residential Design Award program referred to as ARDA is an event which recognizes the outstanding efforts of residential design professionals.

The past 11 years as chairman of ARDA I have viewed thousands of design projects.

There has never been a year the quality, variety of design style, size or values which surprise me more than the previous year. This year has been no different.

The projects submitted for the 2016 event have been nothing less than Residential Art. Each of the design professionals who participated in this merit award program are to be commended for their attention to detail and sharing their design talents with the entire residential design community and the world. The entire world has had the opportunity to experience the residential art through the Global Choice category of ARDA. The Global Choice category is promoted through social media and the designers themselves. This year there were 2,400 votes cast by the people of the world. This is a new record and one I believe will grow in the following years of ARDA. Participation in ARDA is a program where the design professionals can participate with the apprehension of high honors and recognition to their peers. To those who have participated but not received the results wished for are still winners. You have developed your own marketing materials you will be able to utilize for years. You have ventured into the unknown with bold designs and artwork that will never be diminished by the years of change. You should all be proud of the work presented. I have been honored to be part of the ARDA program over the years and appreciate the assistance of the AIBD staff especially our Executive Director Steve Mickley.

Without the assistance and professionalism the ARDA program would not have grown into what it is today.

I would be remiss in not mentioning Mr. Jim Vann. Jim has been the emcee for the recognition program for as many years I have been involved. His professionalism and sense of humor has always made the event enjoyable. Ted Hake CPBD also needs to be recognized for his assistance and continual support over the past years.

Stepping down as Chairman of ARDA is bittersweet. I will miss viewing all the wonderful residential art the design professionals are sharing.

Karen Kassik Michelsohn FAIBD will be taking the reigns of ARDA and I believe will bring the program to the next level. Karen has vision and passion for design excellence that will flow into the success of the ARDA program in the upcoming years.

WINTER 2016 - 03

Incoming ARDA Chair’s Message Karen R. Kassik-Michelsohn is an expert in residential design. She has been designing custom homes and remodeling existing homes for over 20 years. Karen is a Certified Professional Building Designer, a Certified Green Professional as well as a Certified Aging in Place Specialist. In addition, Karen was AIBD’s 2014 Designer of the Year.

I

am very excited to become the new Chair for the American Residential Design Awards program. I have admired the program for years and have watched with great interest the growth and prestige that ARDA has garnered.

Following Mike Battaglia and his committee will be a daunting task, but we are motivated and ready to take ARDA to new heights. We are hard at work to expand our contact list as well as our marketing efforts to raise awareness and participation in the program. We are open to the entire Residential Design world, not just members of AIBD. We welcome any and all entries of outstanding design.

To my knowledge, ARDA is the only pure Residential Design recognition award. Therefore, entries are not grouped in square footage or project value classifications. If you are not familiar with our program, please log onto AIBD.org/arda for more information.

If you would like to serve on our committee or if you know someone who would be a good lead to add to our mailing, please contact myself or Steve Mickley. Help us help the Residential Design industry make our world a more beautiful place to live.

Working Drawings

2016 GRAND ARDA: Michael Roth Design Group

The municipality has height restrictions for this particular zoning, but the designer rose to the challenge and overcame it. The rear of the property has a water view, and the beach look and feel of the home fits right in. All of the public spaces of the home are on a separate floor from the private spaces, which prevents guests from accidentally entering private spaces during gatherings.

Renovations

2016 GRAND ARDA: Mountainworks Custom Home Design This decrepit shack became a beautiful cottage in the woods. Working within the existing footprint, the new home has an almost story book feel. This quaint feel and attention to detail makes this home stand out. Because the original home was built in 1920, before government setbacks and restrictions, it was “grandfathered in� so the new home design had to stay within the exact footprint of the existing structure.

2016 GRAND ARDA: Robert Klob Design, Inc. This designer brought a 1950’s home into the modern day. This remodeled home underwent a huge transformation that required an extensive remodel and addition. The design style is “Desert Contemporary” with a mid-century modern influence.

2016 GRAND ARDA (Also Best In Show) : Ashton Woods The goal of this home was to invoke the feeling of “Southern Hospitality.”

The designer improved accessibility tremendously in this family kitchen.

Outdoor Living Design 2016 GRAND ARDA: Phil Kean Design Group

This designer blurred the lines between indoor living and outdoor living by expanding the living space outdoors.

Multi-Family Designs

2016 GRAND ARDA: Miller Architecture This designer created loft duplex and stacked loft duplex housing for off-campus students. The strongly sloping and lived-in roofs offer a dramatic departure from any of the student housing found on campus.

Custom Home Design

2016 GRAND ARDA: Retro+Fit Design, LLC This designer designed this home to maximize views while also implementing sliding wall systems to bring the outdoors inside.

The judges referred to this as a great contemporary design, and were impressed with how the cantilevers add visual interest. The house appears to change on approach, like a kaleidoscope.

The designer faced challenges involving the slope of the lot, protected ridge ordinances, and guidelines involving tree removal.

WINTER 2016 - 24

AMERICAN RESIDENTIAL DESIGN AWARDS (ARDA)

2016 GRAND ARDA: Sater Design Group, Inc. This design has great curb appeal.

Though it is an all new design, it looks like it grew naturally over time with additions. The massing are well blended, and the roof lines bring the composition together. The client spent most of their childhood in Spain and desired Andalusian influence. The designer also achieved major goals in energy efficiency and sustainability. The energy costs are only a fraction of what most other homes of this size would have, and every single room of the home has natural lighting.

WINTER 2016 - 25

Custom Home Design

2016 GRAND ARDA: Mountainworks Custom Home Design This home was designed to fit within stringent setbacks imposed by their development due to its proximity to the golf course. There are several pocketing disappearing doors and windows that seamlessly open the interior and exterior space to one another. The judges said: Check out that turret. This home is large in size but still manages to feel intimate. The old world detailing invokes the feeling of another time.

AMERICAN RESIDENTIAL DESIGN AWARDS (ARDA)

2016 GRAND ARDA: Barron Custom Design, LLC

The clients of this design wanted to take advantage of the sprawling views around them, but avoid direct sunlight coming from the west in the afternoons. A major aspect of the design was that the clients were fond of entertaining and wanted their space to reflect that. The center of the home has a large fireplace that connects the living and dining areas. The stained concrete floors in some rooms flow seamlessly into warm wood floors in other rooms. Outside is a large veranda with an outdoor kitchen and a firepit.

WINTER 2016 - 27

Custom Home Design

2016 GRAND ARDA: James S. Collins Architect The client of this designer requested that the home fit in well among much older homes in a historic neighborhood known for high quality designs and craftsmanship of the first quarter of the twentieth century. This home features many designs characteristic of Colonial Revival dwellings, such as white lime washed brick exterior, chimneys and dormers. Aside from the normal rooms found in a home, this home has separate bedrooms for the teenage sons, who each have their own bathrooms and closets as well.

This home is built on lands previously utilized for coal mining, and the design pays homage to its site and rich history. The small cozy footprint of the house is offset by the high ceilings on the main level allowing the house to feel larger than it appears on plans. The rich colors of this home give the property a warm and cozy feel while still maintaining a contemporary style overall.

This article is one of many to follow regarding Technology, BIM and the Building Designers new foothold in today’s world. Check in regularly for news, information and advice. AIBD

We now have National BIM Standards in the United States (NBIM-us) and across the world and there are goals being met by multiple countries to standardize the practice of BIM for any type of building, residential and commercial. Again, the residential industry in the United States is being left behind because the BIM focus has been on the commercial industry and the fast-pace production builders focus for fast delivery and monetary gains. They could gain so much more ground with a BIM-based procedure within their office and design teams. Their design teams and sales staff could gain a great amount of traction as well.

I have joined forces with multiple groups as an AIBD Representative to change that. As Building Designers we need to band together for many reasons, this being just one of them.

Another reason for my involvement is to bring more awareness of AIBD Designers in general. If you have interest in aiding any of the efforts feel free to contact me anytime.

The AIBD is currently working on getting a BIM-r Certificate Program up and running.

Keep your eyes peeled for announcements in the AIBD Monday Minute and this magazine for updates and call to action announcements.

PUTTING TIGHTNESS TO THE TEST

Have

you ever said or heard others say that “we build houses too tight”?

I have been addressing this concern for the last 30 years and I hope this article helps you understand the metrics of air tightness and how improving air tightness can help you meet the ever-increasing expectations of homeowners. First know that constructing tight buildings is a requirement in an everincreasing number of communities, building codes and energy efficiency programs.

For example, at the time of writing this article, 16 states in the US have adopted either the 2012 or 2015 International Energy Conservation Code (IECC) that require mandatory air tightness levels. Similarly, every energy efficiency program such as ENERGY STAR, NAHB Green and the various LEED programs all require some form of air tightness testing. Even where not required, air tightness testing is a very cost effective way to know where you stand and to improve the training of building crews and subcontractors to optimize air leakage control in the homes you design and build.

Just before we get to the technical aspects of the metrics or air tightness ask yourself this: how many holes do you think your typical new home buyer wants you to leave in their walls or attic? The answer is of course none. Homeowners understand that with unwanted air leakage comes noise, dust, pollen and other allergens with a negative impact on heating and cooling bills. If you recall your building science training you will also recognize that unwanted air leaks in walls and attics introduces water vapor into

those cavities. Imagine a cold day in winter, with warm moist air rising into an attic space that has gotten colder and colder over the years as we added more and more insulation as part of the ever-advancing code requirements. That warm vapor condenses in the attic, compromising the roof deck with potential mold or rot.

Conversely, imagine that hot, sticky summer day with the air conditioner cranked down. Any air leakage from outside into the wall or attic assembly could result in condensation inside those cavities that are now filled with insulation.

The critical connection we all need to remind ourselves of is that as we added insulation to buildings, we created temperature differentials across the building enclosure elements and any air leakage across that temperature differential can result in condensation in those cavities.

In short, the more you insulate, the tighter you need buildings to be.

Understanding the metrics

The method of choice for measuring a home’s tightness is a blower-door test. The most common techniques follow the ANSI/ASTM-779-99, “Standard Test Method for Determining Air Leakage Rate by Fan Pressurization” or the CAN/ CGSB 149.1 “Determination of the Airtightness of Building Envelopes by the Fan Depressurization Method.” These standards follow similar test protocols and give very similar results or modified versions of this protocol to suit specific energy program parameters.

Metric 1: ACH@50Pa

(Air changes per hour at a pressure difference of 50 Pascal.)

This metric takes the CFM@50Pa number, multiplies it by 60 (minutes in an hour), and divides that result by the volume of the heated area of the house. This metric makes comparing houses of different sizes possible and has become the most common metric referenced in codes and energy efficiency programs. A good goal for most builders in any climate zone is anything under 2.5 ACH@50Pa.

Metric 2: ELA@10Pa

A large fan is installed in one exterior door of the house. It creates a pressure difference of 50 Pascal across all sides of the house or building at once. This is roughly equal to the pressure of a 25 mph wind. While a house would never experience this naturally, it does enable simple and accurate leak detection. The fan is calibrated and the operator records the cubic feet per minute (CFM) that the fan is delivering at 50 Pascals of pressure (CFM@50Pa). Often a range of pressures and airflows is recorded so that the results can be reported in a variety of ways, including the three preferred metrics discussed later.

(Equivalent leakage area) Technically this is a calculated, extrapolated number used for energy modeling but for your purposes you can think of it as the size of a theoretical hole in a wall if you combined all the air leakage points in a house into one round smooth hole and measured the amount of air flow at a pressure of 10 Pascal. This metric allows for simple communication as crews, subcontractors, and homeowners can often relate to the size of a hole in square inches better than trying to imagine CFMs of air flowing through multiple small leaks. Using a 2,000-square-foot house as a reference, a good tight house would be less than 100 square inches of leakage – think the size of a piece of paper.

Metric 3: CFM/ft2@50Pa

(Normalized leakage rate) This is another way of comparing houses of different sizes. The CFM at 50 Pa is divided by the building enclosure area to get CFM/square feet of enclosure. Many building science folks think

Tight is good, but ventilation is critical

We used to rely on windows and natural infiltration of air into a home to maintain air quality. This wasn’t particularly effective and certainly wasn’t energy efficient. Moreover, because of noise, dust, security and energy concerns many homeowners are now reluctant to leave windows open for a sufficient length of time to ensure adequate fresh air ventilation. Fortunately, mechanical ventilation is now a requirement in the International Residential Code for houses that have an air tightness of 5 ACH@50 Pa or less. Better yet, there is the very helpful ASHRAE Standard 62.2, Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings. This standard lays out essential requirements for proper ventilation.

There is a helpful table that makes it very easy to determine the capacity for continuous ventilation requirements in most

homes. Below are excerpts from the sizing table in ASHRAE 62.2 – 2013 to demonstrate the order of magnitude of continuous ventilation required.

For example, from this table you can see that a common 4 bedroom, 2500 sq.ft. home needs just a capacity of 120 CFM of ventilation air to maintain acceptable air quality. This capacity can be accomplished with a simple selection of quiet bathroom fans, designed to be able to operate continuously. Of course, a more energy efficient way would be design for an energy recovery ventilator (ERV) with a capacity of up to 120 CFM to provide the continuous ventilation capacity. Experience has shown in jurisdictions that have a history with ERVs, they are typically installed for well under $2000.

about a continuous line around the cross sections of the building – we refer to it as the red dotted line. A line that indicates the placement of the air barrier and the connections to make sure it is continuous. Materials such as drywall, wood, wood sheathings, many housewraps, foam insulation, windows and poured concrete are all excellent air barriers. We just need to help builders and their trade contractors with strategies that ensure they are continuously sealed. Remember the sum total of all the holes should be no more than the size of a piece of paper. There are many resources for detailing air barriers such as the materials provided by the ENERGY STAR for New Homes program. You will also fine excellent details and animations on our free APP. Go to www.constructioninstruction. com or download the App from the iTunes store.

Therefore, you can go ahead and get rid of all the unwanted holes in walls and attics with the confidence that there will be two ventilation systems in the homes you design and build; the traditional window approach and the controlled, continuous mechanical ventilation system described in ASHRAE 62.2. The result is a quiet, efficient home with controlled, continuous fresh air that can be filtered, heated and cooled to provide the Tight is good, tighter is better.
