Inexpensive Solar Energy Solution
When I feel the need for some inspiration I always head over to Ted and watch one of the presentations. I came across the one below where Bill Gross talks about using inexpensive materials and a Sterling engine to generate energy instead of costly solar cells.
Water Smart Landscape Conversion Started
We decided to convert our grass filled front yard to xeriscape. The great thing about doing this is if you live in Las Vegas call the Southern Nevada Water Authority before starting the conversion you will potentially get up to $1.50 sq/ft back. If you do this it is important to have them come out first before ripping out turf.
There is one thing I know about something as labor intensive as landscaping, that in order to get it done in a timely fashion we are going to have to pay to have someone do at least part of the project. To save some money we’ll do most of the demolition work ourselves.
The Plan
After sketching out the dimensions of the front yard, we came up with an overall plan for the front yard. We can’t afford to do everything we want all at once so we’re going to break it up into 3 stages. Here are some of the things we would like to incorporate into the new front yard.
- 2 different sizes and types of rock
- Additional parking
- A small wall in front to keep debris and the random dog out of the yard
- Minimal plant maintenance
Stage 1 – Remove all the existing decorative walls, the planter box attached to the front of the house, sandstone gravel and turf. Once that’s finished we’ll work with a landscaper to put in the new gravel and irrigation in.
Stage 2 – Figure out a paver solution for the additional parking section. I want to use pavers so water can go into the ground and not the street.
Stage 3 – Put in the stacked stone wall in front of the house.

Water-Efficient Lawn Sprinklers Study Started
The Southern Nevada Water Authority started a study to test water-efficient sprinkler heads. The new technology is supposed to reduce water use up to 30 percent.
These high-tech water smart sprinklers typically apply water more evenly, reducing dry spots without overwatering. They also apply water at a rate that allows it to be more readily absorbed into the soil instead of running off.
Applying Thermal Barrier Paint On An Attic Roofline
A little while back I wrote a post about Sherwin Williams having a thermal barrier paint called E-Barrier. I decided to start my attic upgrade with this product. There are plans to seal up and increase the insulation up there, but to do this project without knowing where to step would probably double the time it took.
Cost Breakdown
| 5 gal. Sherwin Williams E-Barrier Paint | $176.00 |
| Painters suit | 10.00 |
| Paint sprayer rental | 56.00 |
| Total: | $242.00 |
The person at Sherwin Williams didn’t want to shake the paint at the store because he didn’t want the aluminum in the paint to create a static charge. Instead I flipped the paint the day before to get all the particulates to the top of the bucket. The day we painted I used a drill and paint mixer for 5 minutes to incorporate the particulates and latex.
- Pressure: 2000-2500 psi
- Tip: .017″-.021″
The one I rented from Home Depot had an Airlessco 517 tip on the sprayer. According to Airlessco’s site this is a .017″ tip.
Preparation for the area included laying down some plastic I already had to protect the carpet, emptying the closet, donning a paint ventilation mask and putting on the painters suit.
Suiting Up For Painting
Our house has two joined attic areas. The first one has all the duct work from the two A/C units on the roof.

I did a horizontal application pattern with some overspray.
It took about an hour to apply the paint to about 500 sqft. of attic space. One thing to remember is to stay hydrated when working in the attic. It was at least 10-15 degrees warmer than it was outside.

The second attic space over the master bedroom has more room to maneuver but there is more electrical work to watch out for.

The second attic area took another hour to spray. I learned a couple of tips from the first attic area:
- Switch to spraying vertically near the bottom truss
- Keep the spray gun 8″-12″ away from the target area
- Use the camera to help identify where some areas were missed

Insulating Outlet Boxes With Spray Foam
One of the most effective things I’ve done in the name of trying to conserve energy and make my older home more efficient is seal the outlets on the outside walls with spray foam insulation.
These are the reasons a latex foam was chosen over the polyurethane type.
- There were too many warnings on the polyurethane spray foams about their flash point being 250° F when cured.
- The latex one didn’t mention any such thing when it was cured.
Latex Spray Foam Insulation
WARNING: When insulating an electrical outlet box make sure the power is off to that outlet until the foam insulation has cured. Follow all manufacturer’s instructions.
Doing the outlets that are on an exterior wall will provide the most impact. The outlet shown had some gaps as large as 1/4″ around it. I felt the cold air freely flowing through the outlet box by just putting my hand in front of it.
Gaps Around An Electrical Outlet Box
With the electricity off, the expanding foam was applied.
Spraying Expanding Foam
This is how I applied the foam:
- from the bottom to the top
- for each side done foam was applied from the back to the front
- foam was purposefully allowed to expand over-filling the cracks in the front
Electrical Outlet Box With Foam
A finger was used to smooth the foam around the outlet box.
Once the foam has cured, the power was turned back on.
