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.

Three Main Aspects: Natural Air Flow, R49 Ceiling Insulation, and Air Tight Electrical Junction Box Covers

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.

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.

Sealing Air Leaks

Warm air leaking into your home during the summer and out of your home during the winter and can waste a lot of your energy dollars. One of the quickest dollar-saving tasks you can do is caulk, seal, and weatherstrip all seams, cracks, and openings to the outside.

You can save on your heating and cooling bill by reducing the air leaks in your home.

Create the Air Tight Seal

Tips for Sealing Air Leaks

re-posted from:
Pie chart shows how air escapes from a typical home: 31% floors, ceiling, walls; 15% ducts; 14% fireplace; 13% plumbing penetrations, 11% doors; 10% windows; 4% fans and vents; 2% electric outlets.How Does the Air Escape?
Air infiltrates into and out of your home through every hole and crack. About one-third of this air infiltrates through openings in your ceilings, walls, and floors.
  • First, test your home for air tightness. On a windy day, carefully hold a lit incense stick or a smoke pen next to your windows, doors, electrical boxes, plumbing fixtures, electrical outlets, ceiling fixtures, attic hatches, and other locations where there is a possible air path to the outside. If the smoke stream travels horizontally, you have located an air leak that may need caulking, sealing, or weatherstripping.
  • Caulk and weatherstrip doors and windows that leak air.
  • Caulk and seal air leaks where plumbing, ducting, or electrical wiring penetrates through walls, floors, ceilings, and soffits over cabinets.
  • Install foam gaskets behind outlet and switch plates on walls.
  • Look for dirty spots in your insulation, which often indicate holes where air leaks into and out of your house. You can seal the holes with low-expansion spray foam made for this purpose.
  • Look for dirty spots on your ceiling paint and carpet, which may indicate air leaks at interior wall/ceiling joints and wall/floor joists. These joints can be caulked.
  • Install storm windows over single-pane windows or replace them with more efficient windows, such as double-pane. See Windows on page 18 for more information.
  • When the fireplace is not in use, keep the flue damper tightly closed. A chimney is designed specifically for smoke to escape, so until you close it, warm air escapes—24 hours a day!
  • For new construction, reduce exterior wall leaks by installing house wrap, taping the joints of exterior sheathing, and comprehensively caulking and sealing the exterior walls.
  • Use foam sealant around larger gaps around windows, baseboards, and other places where warm air may be leaking out.
  • Kitchen exhaust fan covers can keep air from leaking in when the exhaust fan is not in use. The covers typically attach via magnets for ease of replacement.
  • Replacing existing door bottoms and thresholds with ones that have pliable sealing gaskets is a great way to eliminate conditioned air leaking out from underneath the doors.
  • Fireplace flues are made from metal, and over time repeated heating and cooling can cause the metal to warp or break, creating a channel for hot or cold air loss. Inflatable chimney balloons are designed to fit beneath your fireplace flue during periods of non-use. They are made from several layers of durable plastic and can be removed easily and reused hundreds of times. Should you forget to remove the balloon before making a fire, the balloon will automatically deflate within seconds of coming into contact with heat.

Why Insulate Your House?

Heating and cooling account for 50 to 70% of the energy used in the average American home. Inadequate insulation and air leakage are leading causes of energy waste in most homes. Insulation:
  • saves money and our nation's limited energy resources
  • makes your house more comfortable by helping to maintain a uniform temperature throughout the house, and
  • makes walls, ceilings, and floors warmer in the winter and cooler in the summer.
The amount of energy you conserve will depend on several factors: your local climate; the size, shape, and construction of your house; the living habits of your family; the type and efficiency of the heating and cooling systems; and the fuel you use.

Once the energy savings have paid for the installation cost, energy conserved is money saved -saving energy will be even more important as utility rates go up.

This fact sheet will help you to understand how insulation works, what different types of insulation are available, and how much insulation makes sense for your climate. There are many other things you can do to conserve energy in your home as well. The Department of Energy offers many web sites( to help you save energy by sealing air leaks, selecting more energy-efficient appliances, etc.

How Insulation Works

How Insulation Works

  • Heat flows naturally from a warmer to a cooler space. In winter, the heat moves directly from all heated living spaces to the outdoors and to adjacent unheated attics, garages, and basements - wherever there is a difference in temperature. 
  • During the summer, heat moves from outdoors to the house interior. 
  • To maintain comfort, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner. Insulating ceilings, walls, and floors decreases the heating or cooling needed by providing an effective resistance to the flow of heat.

  • Reflective insulation or Radiant Barriers works by reducing the amount of energy that travels in the form of radiation. Some forms of reflective insulation also divide a space up into small regions to reduce air movement, or convection, but not to the same extent as batts, blankets, loose-fill, and foam.
