Ensuring Success StLouis Small Biz Energy Efficiency Design Build Project

In todays day and age of small business enterprises I rarely find that a local St Louis area small business is actually thriving.  And when I learned that this successful small business needs to expand to meet the needs of her growing business I was more than happy to assist her in making her business a continued success by utilizing proven advanced energy efficient construction techniques for this Attic Conversion.

"Proper Design Build Energy Conservation Techniques used in this project will ensure that this business owner will keep the energy costs low and comfort levels high-Scotty,Scotts Contracting"

Here is behind the scene work on the Design Build Energy Efficiency-Attic Conversion and the Small Business Customer Must Haves for the project and how I am going to convert the unused attic space into a functional and energy efficient design build project that meets and exceeds the clients requests


Here are the clients Must Haves:
  • Energy Efficient Design (part1)
  • Open Floor Plan (part 2)
  • Kid Sized Plumbing Fixtures located in the Bathroom (part 3)
  • 1 Sink located outside the Bathroom with Extra Counter-space (part 3)
  • Flooring options require materials that do not transfer sound and are easy clean up (part 4)
  • No Harmful VOC Building Products (part 4)
  • Cost Effective (part 4)
  • Financing this Small Business Success Story Design Build Project (part 5)

Designing for Energy Efficiency
Since this project will be in the top floor of a two story building special attention was given to ensure that proper levels of insulation are utilized as well as eliminating air leakage.  


Here is a CAD drawing of the planned Ceiling and modifying the existing Roof Construction that addresses building code requirements for energy efficient design and construction.

In the above photos you see that Natural Air Flow is mentioned numerous times.  The importance of natural air flow-is not only suggested it is required by the new building codes that are slowly being adopted and utilized in today's energy efficient building designs.

What gets me is that why some builders leave out this crucial step.  Its not a new concept and one that I learned in my first year of Drafting classes in 1989 while designing my final year Residential Home Drafting Project.  

What this natural air flow does is keep the upstairs cooler in the summer and is needed to assist in eliminating ice dams during the winter.

Rule of Thumb for determining this natural air flow from eve to roof peak is: 1 square inch for every square foot of space.  

This 1 square inch is then divided equally in half between the top and bottom of the building.  In the case of this building we will be using: Soffit Vent as well as Roof Peak Vent and to ensure there is unobstructed air travel Air Baffles will be utilized in the areas where the insulation contacts the underside of the roof.

Never let a Building Contractor neglect this important step in any of your building projects.

Stay Tuned for Part 2 of the Design process where I address the open floor plan.

#DesignBuild Energy Efficiency-Attic Conversion

My next Design Build Project will be converting this unused attic into Energy Efficient and usable 2nd Floor Space.   

We will be performing major Energy Conservation Build Techniques as well as using Advanced FramingMethods on this Green Build Project 

Upon completing we will have the following RValues: R19+ in the wall, R49 Attic, R13+ in the Floor. 

My plans also call for Air Tight Electrical Junction Box Covers in the Attic as well as 6mil Poly Air Barrier for the Interior Walls. 

Stay Tuned for more project photos as well as otherCAD Drafting details by Scotty-Scotts Contracting . 

Build Green Scotty!

ICE Dam Prevention

Ice Dam Prevention for Homes and Business is a simple process to correct and prevent.  Scotts Contracting recommends installing a Ridge Vent and Soffit Vents to prevent Ice Dams.
"I feel that Ridge Vents-when coupled with Soffit Vents are one of the Greatest Energy Efficient Building Materials on the Market today to prevent Ice Dams". Scotty-Scotts Contracting, St Louis Renewable Energy

In a cold climate, the primary purpose of ventilation is to maintain a cold roof temperature to avoid ice dams created by melting snow and to vent any moisture that moves from the conditioned living space to the attic.

"So much information has been devoted to the subject of roof venting that it's easy to become confused and to lose focus. So I'll start by saying something that might sound controversial, but really isn't: A vented attic, where insulation is placed on an air-sealed attic floor, is one of the most underappreciated building assemblies that we have in the history of building science. It's hard to screw up this approach. A vented attic works in hot climates, mixed climates, and cold climates. It works in the Arctic and in the Amazon. It works absolutely everywhere—when executed properly.[ http://stlouisrenewableenergy.blogspot.com/2011/08/roof-venting-and-its-importance-for.html ]"


In the Proceeding Post Green Builder-Scotts Contracting,St Louis Renewable Energy posted: Why is there ICE in my Attic and where did it come from?  The following CAD Drawing by Scotts Contracting shows how ice dams are prevented.

Why is there ICE in my Attic and where did it come from?


  • Ice Dams are created when the Hot Moist Air Rises from the Interior of the Building.  
  • Any snow built up on the roof will now also thaw and refreeze at the gutter area and build up eventually working its way under the shingles and into the home.

  • As the Hot Moist Air Rises into the Attic and meets the Roof Framing System.  Condensation Occurs on the Cold Framing Members consisting of: Rafters, Roof Trusses, Roof Decking

  • As the Condensation Cools the Moisture in the Air Freezes on the Roof System and is why venting the attic is suggested.
