I’ve been remiss on posting tips lately. There has been a lot going on! With the construction underway on the Sand Hill Farm apartments, I thought I would share a few simple sound proofing solutions we are using on this project. Most of these are green solutions as well as sound proofing.
2′ Stud Spacing:
First, we have used 2′ spacing on studs wherever possible. On the green side, every stud removed from the project is a savings of cost and and material. Literally hundreds of studs were removed from the project through this reduction of studs as well as doing things like using California Corners. Sound travels more easily through hard surfaces. By eliminating the number of studs we’ve eliminated the sound transfer points. On the exterior, this has the other benefit of allowing more insulation. Just as the studs transfer sound, they are more efficient at transferring heat. Every stud removed is one less heat transfer point as well. That stud space is filled with insulation. We are using 2×6 exterior wall framing which allows for additional insulation.
On the inside, it is more directly sound transfer. We have continued to use 2′ centers wherever possible. This helps sound transfer throughout the building.
In the walls between the units we are not only using 2′ centers, but we are using a staggered stud wall. This is done by using 2×6 top and bottom plate and then staggering the studs from one side to the other every 12″. In the picture to the left, you can see the green (treated) 2×6 base plate and the staggered 2×4 studs attached to it. This effectively give you 2′ centers on each side and reduces the direct connection for sound transfer to the top and bottom plates. We will then weave sound batt insulation between the studs for additional sound deadening. There are a few exceptions where a 2×6 column is required, but in the majority of these adjoining unit walls, the staggered stud configuration is continuous.
Open Web Floor Trusses
The floor trusses between the first and second floor are open web trusses. Using open web trusses reduce those hard service transfer points that you would have with standard dimension lumber or even with I-joist. The other advantage to the trusses is we can increase the spacing from the standard 16″ spacing used for solid wood to 19.2″ on centers. Sound batt insulation will be placed between the trusses to further reduce sound transfer.
Before the drywall is installed on the ceilings, we are installing sound dampening channels. These are Z shaped channels that run perpendicular to the floor trusses. The changes the hard surface connection to just the 3-4 square inches at each channel to truss connection. The Z shape of the channel allows some minimal flex which again will absorb some sound.
5/8″ Drywall Walls
Normal residential construction would have 1/2″ drywall on the walls and 5/8″ drywall on the ceilings. We are using 5/8″ drywall throughout. The additional mass will not only provide a more durable surface when spanning the 2′ stud spacing, but it will also help reduce sound transfer.
Sound dampening Underlayment
All of the floors on the second floor will be laminate. This was chosen after talking to several realtors. The number of people having allergy issues has increased and this has increased the popularity of hardwoods and laminate floors. Hardwood floors tend to transfer sound though. Laminates reduce that. We have chosen a laminate plank flooring that will simulate a hardwood look, but absorb more sound. In addition to this, using this material allows us to put down a sound dampening underlayment beneath the laminate planks adding one more layer of sound protection. This system has the added benefit of being nearly impermeable to water.
The Benefits of Building a Custom Home
When it comes to choosing your next home, you may be torn between buying an existing home and working with an architect and builder in order to build a custom home. While pre-existing homes offer the ability to move in right away, they may contain hidden costs, like the need to upgrade appliances, renovate or build additions. Custom homes, by contrast, are completely move-in ready with all the features and square footage you need to make your home comfortable and functional.
1. More Home for the Money
Custom homes can offer more home for the money. When home buyers purchase preexisting homes, they often need immediate maintenance and upgrades. At a bare minimum, you’ll probably find yourself gutting the kitchen and the bathrooms and completely replacing them, which adds to the overall cost of the home. Likewise, the existing home may contain features you don’t want and exclude features you do want.
When you build a custom home, you are only paying for the square footage, features and customization you want in order to maximize the home’s flow and function.
2. Built to Your Specifications
Custom homes can be built to your specifications and your family’s needs. Most preexisting homes include one or two bathrooms and two to three bedrooms. If you have a large or growing family, own your own business or work from home, an existing home may not be able to meet your space needs. Custom homes can be built with as many bedrooms as you need, modern kitchens with all the right materials, home gyms, offices and great rooms and/or gathering rooms that are large enough to entertain friends, family members and clients or coworkers.
3. Better Energy Efficiency
Older homes are not as well insulated and do not typically contain as many green features, unless the previous homeowners have performed extensive upgrades. By contrast, custom homes can be built to your energy-efficient standards. Instead of fiberglass insulation, you can request spray foam insulation. You can request energy efficient windows, doors and roofing, and you’ll be able to choose between standard hot water heaters and tankless hot water heaters. In some instances, you may even be able to install solar panels on your new energy-efficient roof in order to further reduce your new custom home’s ecological footprint and save money on your energy bills.
4. Appliances Included
Custom homes include the appliances, and you can negotiate with the builder to include upscale or luxury appliances instead of the standard builder-grade appliances. When you purchase an existing home, if the appliances are included, they are often several years old, outdated and may not include the features you desire.
5. Better Privacy
When you decide to build a custom home, you can choose your lot and the style and orientation of your house. This gives you more privacy options than purchasing an existing home. With a custom home, you have the option of setting the home further back on the lot, orienting the home’s design and layout and customizing your landscaping in order to maximize privacy.
6. Move-in Ready
Custom-built homes are ready for you and your family. Once they are finished, you do not have to worry about making upgrades or repairs for several years, and many new, custom homes come with home warranties so that you can have increased peace of mind.
As the hype grows, I’ve been thinking about the solar eclipse on August 21st. Thanks to Waffle House, I found this handy map (see right) in case you want your eclipse viewing “Smothered & Covered”. I heard on the radio that Krispy Kreme was planning competing events. Chocolate Glaze! Unfortunately, Indiana will be mostly bypassed for the total eclipse. We’ll only get a side view. That should still be cool and weather permitting, I’m sure I’ll step out side to check it out.
My friends around Atlanta are planning parties and events. Any excuse for a party and a day off work, right? The University of Georgia is planning a party in Sanford Stadium. (Article here) Do you tailgate for an eclipse? Knowing the Bulldogs, the answer to that will be a resounding YES! Ha!
One of the other interesting tie-ins I saw was with the Nest thermostats. I’ve talked about them before here. They’ve been through a few updates since then and I chose to install one in my home. So far I’ve been pleased. More than similar devices, I have observed Nest really trying to make the green connection and not just personal energy cost savings. They send out a report on how many “leafs” you earn each month for energy savings along with a comparison to other Nest owners. There is a running total on their website showing their estimate of how many Kwh of energy that has been saved by their devices.
The tie-in to the eclipse is that in their blog, Nest repeats a report that suggests the solar eclipse, as it blocks out solar panels, will reduce green energy production by as much as 9,000 MW resulting in traditional systems coming back on line to pick up the slack. “At Nest, we think of these high-demand times on the energy grid as rush hours.” They suggest that if you opt in, their thermostats will automatically cool your home a little extra before the event so that it can reduce the load during the event. Personally I think that’s as much marketing as an actual need, but it’s still an interesting concept and it’s another reminder of how the Internet of Things continues to find new ways to work for us.
For those of you in Culver, there is going to be presentations this Saturday at the Culver Union Township Public Library at 10:30 and noon talking about the eclipse. (The noon event was added after the flyer came out.) Dr. Angela Meyer from Culver Academies will give the presentation. Those that attend will receive NASA approved viewing glasses for Monday’s eclipse. This should be an informative event!
Maybe I’ll see you out in the semi-darkness on the 21st. That is if I don’t accept an invitation to go to Atlanta and get the full effect! While I doubt this will be any kind of life changing event, it is one of those cool and rare physical phenomenons of which we should all take advantage. Hopefully for most of us it’s not literally a once-in-a-lifetime event, but it is pretty rare… And unlike most astronomical events, you don’t have to get up in the middle of the night to see it! Bonus!
Portuguese Architects have designed rotating homes that follow the sun in much the way Sunflowers do. Not only do they rotate to maximize the time their solar panels are 90 degrees to the sun, but they also can reconfigure themselves internally to optimize the space for maximum solar gain. The Architects claim the homes can produce five times as much energy as they consume. Read the entire article here on the Hexapolis site.
Canopy Stairs are a cool idea I ran across in a tweet from the Hager Group. Designed by a pair of graduates of the Royal College of Art, the stairs create a spiral stair case around the trunk of a living tree without harming the tree.
While the whole system was worked out with consultation with arboriculturists to assure there would be no detrimental effects on the trees, there sure is a lot of backlash from the tree huggers in the comment section at the bottom of the article. What they seem to be missing is that this is designed to be a temporary, reusable system. The system is designed to distribute the loading around the trunk and would appear to minimize any damage to the tree. As a Landscape Architect, I would suggest this is good stewardship. It enhances the highest, best use of a natural resource with minimal or no damage.
