The World Green Building Council tells us that combined, buildings and construction account for, “39% of energy-related carbon dioxide (CO2) emissions when upstream power generation is included.”1 In a previous post, I discussed how HVAC units2 (heating and cooling) systems are responsible for the lion’s share of this and a proposal to capture that carbon dioxide to generate hydrocarbons. This article discusses using paint to minimize CO2 in the first place.

The Quest: Finding an Effective Paint

Researchers have been attempting to come up with products to raise the efficiency of cooling and heating for years. Many types of reflective paint have been developed for the exteriors of both homes and office buildings that would reflect away sunlight resulting in a reduction the temperatures on the interior.

Up to this point, none of these reflective paint products have been successful in deflecting enough of the Sun’s rays that would result in the building’s temperature lower than the ambient conditions. That may be changing.

Researchers in the US say they have developed a white paint with strong cooling properties. Prof Xiulin Ruan, from Purdue University in Indiana says, “In one experiment where we put a painted surface outside under direct sunlight, the surface cooled 1.7C below the ambient temperature and during night time it even cooled up to 10C below the ambient temperature. This is a significant amount of cooling power that can offset the majority of the air conditioning needs for typical buildings.”

The Tech Behind the Paint

The researchers found that the key is adding calcium carbonate. By utilizing a high concentration of this chalky substance, differing the particle sizes, they developed a paint that reflected an astounding 95.5% of sunlight.

Prof Xiulin Ruan said, “Sunlight is a broad spectrum of light wavelengths. We know that each particle size can only scatter one wavelength effectively so we decided to use different particle sizes to scatter all the wavelengths. This is an important contributor eventually resulting in this very high reflectance.”

The paint may have a broad range of applications, in particular data centers, which require large amounts of cooling power. Because this particular paint doesn’t contain metal, it is not likely to interfere with various electromagnetic signals. This makes it ideal for cooling telecommunications equipment.

Of course, it goes without saying that there will be a number of steps to go complete before this product can be put on the market, because like any other product, it needs to be tested for its reliability and efficiency in the long term. The researchers remain optimistic; they have already filed patents and there is already a strong interest from major manufacturers. Cooling paint that can cut emissions from buildings of all types will lower costs across the board.

Recent estimates report that 33% of Americans are self-employed in some capacity. Now, the report didn’t break it down into full-time or part-time details, but it means one thing for certain — lots of home offices! You might need one for the first time because of being locked down thanks to the COVID-19 pandemic. Whether you’re remodeling a bedroom into your office, or remodeling your current one, you can use these home office refurbishment tips.

Office Interior Lighting

All interior lighting is not the same. In the office, in particular, it falls into three distinct categories: general, task, and accent lighting. How much of each you use depends on your needs. General lighting is often implemented with overhead fluorescent fixtures. Most home offices just use task lighting.

Task lighting is used to focus on your work area to avoid eye strain. Good choices here are undercabinet fixtures, or track, monorail, or Y lighting systems with halogen or LED bulbs. Accent lighting usually illuminates artwork. This is taken care of with ceiling-mounted fixtures.

Buy Ergonomic Furniture

This is important for your comfort and long-term health. The two most critical pieces are an ergonomic office chair and computer desk. Adjustable standing desks are getting to be more popular. Before shopping, know what you need. Draw a detailed plan noting where things should be situated. Size is important; be sure everything will fit into your space.

Although it might be tempting to do so, I wouldn’t recommend placing the fax, copier, and printer where you can just reach over to make a quick paper grab. Why? Because you need to get out of your chair now and then to get the blood flowing! My Garmin 235 GPS watch actually lets me know when I’ve had too much butt-time.

Flooring – Choose Wisely

You’ve got many choices when it comes to flooring. Carpet is the best choice for sound control and it is forgiving; you’ll be spending a lot of time on your feet. The downside is that occasionally you’ll have to hire carpet cleaners or rent a machine at the store. If you’ve got a lot of carpet in your home, go ahead and buy a carpet cleaning machine. It will quickly pay for itself. Who knows how nasty those grocery store ones are.

Are you after a a more contemporary look? You might consider hardwood or laminate flooring. When it comes to sprucing up your home office, consider that you’ll be spending more time in there than you would a conventional office (Netflix). Plan accordingly.

Upgrade Your Office walls

Your office walls are important. You should choose a color that you like, of course, but it should also be a color that is soothing enough to allow you to focus on your work. Small office? Here are some paint illusions to make the space seem larger.

I hope these home office build-out tips have inspired you and given you some food for thought. Always check the latest IRS guidelines to maximize your deductions. It’s like getting a pay raise! Please participate in the poll on the right-hand sidebar of this article. Thanks!

Paint Like a Pro with These 10 Tips

Prepping a home for painting

This article was updated on 09/27/20.

Nothing enhances the exterior of a home like a fresh coat of paint. Although the job seems straightforward enough, there are things you can do to make the job easier, faster, and more efficient. One thing you should know at the outset — older homes might have lead-based paint. Have yours tested before embarking on this job. That being said, read on for 10 tips to paint like a pro.

  • Scrape and sand all surfaces prior to washing. Although some painters like to wash first and then sand and scrape, this can leave behind dust that prevents the new paint from sticking as well as it should.
  • When power washing, keep the setting on low. High pressure from a power washer will force water into the wood. Even when the outer surface seems dry, it may have moisture trapped inside. What should you wash with? I like to use a tablespoon of dish soap with a mixture of TSP (trisodium phosphate) and bleach. The dish soap helps the solution to cling to the siding and trim rather than running off the house. This is the same principle as using a bit of soap as a surfactant when spraying garden plants.
  • Cover plants, cars, exterior lighting, and anything else that might be affected. Like most situations, an ounce of prevention is worth a pound of cure. Use breathable drop cloths for plants so they can breath. Protect lights, doors, and windows, with Cling Cover plastic.
  • Use a high-quality primer. Always prime bare spots before painting. If the home has oil-based paint that is peeling and cracking and complete removal is not a good option, use a product such as XIM Peel Bond primer.
  • Use the right tools. This should be obvious but many beginning painters and weekend warriors just try to “get by” with what they have on hand. You get what you pay for. Go for the pricier brushes, rollers, and sprayers. They might set you back a bit in the beginning but the finished job will be more professional.
  • Wear knee pads when working on a ladder. There’s always a rung where your knees are, right? Without knee pads to cushion your kneecaps, they will be squealing at you by the end of the day and tomorrow won’t be any better.
  • Plan to spend more time to paint window trim. Painting in the field might be a breeze, but window trim is confoundingly time-confusing. The devil is in the details and the time to apply painter’s tape and sanding really adds up.
  • Don’t paint into the evening. The main issue in the evening is that condensation forms on the surface of the paint when the sun goes down, particularly during the spring and summer. On wet paint, this causes the water-soluble components to break down and rise to the surface. This is called surfactant leaching. After the water evaporates, you’re left with a waxy-looking area. It may go away but there’s no need to take a chance to begin with. In the late afternoon, stop painting and do prep work for the next day.
  • Prevent sticky windows and doors. Where two dry surfaces painted with latex meet, they want to stick to each other. You have most likely noticed it yourself, even on drawers and garage doors. It is completely normal and is called blocking. You can prevent it with a thin coat of furniture wax.
  • Finally, don’t forget on-going maintenance. You might think you’re done, but that is just an illusion. Things like repairing caulking and touching-up paint should be done on a regular basis. Always write down all the details of the kind of paint, sheen, and color of paint that you used.

I hope these 10 tips to paint like a pro will make your painting adventure the best it can be. Doing it yourself can save you a lot of money if you have the time and inclination. Any specialized equipment like a spray rig might be available for renting.

5 Ways to Refresh Your Walls on a Budget

This article was updated on 09/27/20.

Face it; contractor-built walls are just plain boring. There’s a reason for that. Actually, there are a couple of reasons. First, it is frugal to blast cheap texture through a spray gun texture hopper for a conventional orange peel texture. Secondly, that blah flat white paint? It is uninspiring but also frugal and allows for new homeowners to upgrade easily to a more attractive color and sheen.

Let’s take a look at some of the options we have for refreshing those tired, boring walls.

  1. Upgrade Your Texture

Contractor-applied texture is great for hiding drywall joints that were not properly finished but it is just a bit boring. Upgrading your wall texture is easy. I like to use a specialty roller like the one pictured below with watered down drywall compound (mud).

Use a drill and a ribbon mixer to thin the mud. It should easily drip off the mixer when the proper consistency is reached.

You can also used a regular paint roller with the nap of your choice for a less pronounced effect.

2  Paint Your Walls to Make Your Room Appear Larger

Not all homes are as large as we want them to be. Older homes can be notoriously small, especially stairways and halls; not a good thing for the claustrophobic among us. But rest assured that there are ways to open up that space.

Lighter color paint, especially in brighter sheens like eggshell and gloss create the illusion of more space. Wallpaper with vertical patterns give the illusion of more height.

3  Paint Over Old Paneling

Dark paneling may have been quite the thing in the 50s and 60s but today it looks old and dated. Removing it can be messy especially if adhesive was used. Luckily, it is easy enough to paint over wood paneling.

If it has vertical grooves, you will need to skim those with drywall compound and lightly sand the surface before texturing and painting.

4  Install Crown Molding

Installing crown molding will give even the drabbest rooms a touch of class. You’re not limited to wood either. Today you can find it in polyurethane and PVC which makes it easy to work with.

5  Install New Door and Window Trim

Contractor-grade door and window trim is just boring. In just a few hours you can remove it and replace it with trim that will give your walls a shot of style and class.

Kits are available at stores like Home Depot. All you will need is:

  • Tape measure
  • Miter saw or radial arm saw
  • Stool or ladder
  • Finish nail gun or hammer and nails
  • Nailset
  • Spackling
  • Paint and brush
  • Painter’s tape


I hope the above tips on refreshing your walls on a budget proved inspirational and informative. Got any tips of your own? Share them with our readers in the comment box below.
