The Skinny On Energy Efficiency

Google's PowerMeter

When faced with building a new home, you may be surprised at the number of options available for lowering your energy consumption, and thus, your utility bills. However, some ideas are better than others, and a good rule of thumb, according to Bethany Jenkins, Vice-President of Jenkins Custom Homes, is to evaluate the product and choose those with a 2-4 year payback. One of the benefits of building a new home – as opposed to purchasing an existing – is the flexibility you have in design. Here are some of our favorite ways to control energy costs:

1. Start with a great design. Your home’s orientation on the lot, as well as the location of windows and doors, can take into consideration cross-ventilation and the direction of the sun in both winter and summer months.
   
2. Have a carefully planned “thermal envelope”. The thermal envelope is a technical term for the insulation in your home. Think of it like a thermos – the quality of the insulation is what determines how hot or cold your liquid inside remains. The same is true of your home. Putting your money into a high-density foam insulation and highly efficient windows will keep your home warmer or cooler, therefore reducing the number of times the A/C or heater has to cycle on and off.
   
3. Require high-performance mechanical systems (heating and cooling systems, hot water heaters), as well as appliances.
   
4. Employee technology when cost-effective (occupancy sensors for lights, A/C & heater, for instance).
5. Carefully placed trees can shade your house from cold winds or the summer heat, and drought resistant landscaping will lower your water usage.  A good landscape architect can design your green space with eye toward lowering your energy costs.
   

Construction Proceeds on Applehead Island

Construction is moving along well on the home currently being built by Custom Home Builder, Jenkins Custom Homes, on Applehead Island in Horseshoe Bay.  The home is framed and in the beginning stages of interior plumbing and electrical work.  This home is being built for out-of-town clients who enjoy the beautiful lake setting as well as the many activities Lake LBJ has to offer. Working with the Jenkins team from out of town has been drama-free, as the clients have taken advantage of the Jenkins web-based “Guide to Picture Perfect Projects” Personal Home page to view progress, project documents, and process change orders.  With these conveniences, the clients have only had to travel into town for a few critical-stage meetings.

Construction on this custom home began in the Fall of 2009 with the bulk head and boat house.  Those are continuing, as construction on the home continues as well.

Top 5 Home Technology Trends

We recently attended the International Builder’s Show in Las Vegas, where we attended lots of seminars.  One of the big topics this year, as in years past, is home technology; however, the twist on this year’s seminars was “affordable technology”.  So many of today’s technologies are affordable and finding them in the plethora of choices is sometimes daunting.  Here are my “Top 5″.

  Convenience. These are the basics, like, when I get up at 3 am to go to the bathroom, the bathroom light comes on so I don’t trip on my shoes.  Convenience may or may not be expensive but can really change your life.

Accessibility. The smart phone has really changed everything in relation to accessibility.  Now, there’s an app for just about everything you can imagine on your home.  Want to watch streaming video of your kids getting home?  There’s an app for that.  Want to turn off the sprinklers because it’s supposed to freeze tonight?  There’s an app for that…  You get the picture.

  Green Technology.  This can mean a lot of things but the most popular ones usually involves some cost savings to the consumer or an ecologically-friendly impact on the environment.  These areas have really evolved recently to include things like tankless hot water heaters, geothermal heating, and solar panels.  These technologies for our homes are very site-specific; some of them are cost-prohibitive in certain areas while other alternatives have a 2- or 3-year cost benefit payout (which is fantastic!).  So, make sure you ask for a comprehensive cost analysis before you begin.

  Anticipation. Much of our new technology is created in anticipation of things to come.  Lately, we have installed a number of whole-house backup generators for our high end clients, for example.  They are anticipating power shortages at some point in the future.  Another example is the 3D technology that is coming, thanks in part to the movie “Avatar”.  At the International Builder’s Show, the speakers informed us that the new 3D technology that we saw on the big screen will some day be in our televisions in our homes.

Convergence.  Convergence in the technology realm refers to multiple technologies coming together to form a single, better solution.  In the home technology world, a great example of this is our ability to tie in the heating and cooling system into the home’s smart panel to allow for sensors in a room that control the room’s temperature when someone walks in the room.  You can imagine the many benefits for this type of feature, especially when you have two people living in a 6,000 square foot home or a couple who only comes to their lake home on the weekend.

There are so many more great new technologies which can be incorporated into a home.  The key is to really analyze how you live in your home and then talk to the experts about what’s out there.  If you are building a new home, do your research and be sure to discuss with your Builder the convenience, accessibility, green technology, anticipation, and convergence technologies which best fit your lifestyle.
