Nip those electricals in the bud.

About 11% of electricity used at home supports our light hungry habits, not to mention our commercial addiction to kicking footcandles into the stratosphere.  Consider the alternatives.

Conservation - reduce the use, now there’s a concept.  Aside from sitting fireside while reading or doing the mending, the ‘energy efficient’ market is coming up with some great ideas for saving energy. 

  • Use LED lights now available in white light and a wide range of styles.  They are very energy efficient and improving all the time.
  • Use low mercury CFLs (compact flourescent lights) or low mercury T8 lamps such as Philips ALTO II for the office or shop instead of incandescent bulbs.
  • Light switch motion sensors can effectively be used in low traffic areas to automatically turn lights off when not needed.
  • Meet IESNA (Illuminating Engineering Society of North America) standards, but don’t exceed them.

Task Lighting – There are some very hip and/or sleek focus lights out there to put the lumens right where you need them. Even some LED tasks lights are available now, which only use 9 watts of power and last for 60,000 hours. (See Herman Miller – Leaf Light)

 

Use the power of the SUN, turn the main lights down (or off) and cool down the watts.  Harvest free light when it’s available. 

  • If you’re building, place windows to strategically take advantage of indirect light when possible. 
  • Use solar shelves or louvers at window interiors to bounce light deep into long spaces.

       

  • Protect against glare with exterior sunshades, interior rollershades (check out Lutron), or with strategically planted trees (and some time).  
  • Light baffles under skylights diffuse light and provide for good acoustics as well.  Certainteed Ecophon is one example.
  • Let there be light! Install a sun tunnel, it’s like a giant task light using the sun.  A reasonable budget for the unit + install is $1,000 on the high side, it depends on the model of course, but also the length of rooftop to ceiling. See Solatube for one of the leaders. 
  •  Be proactive about lighting at home or work, or in your next project, and reap the benefits of lower electrical bills and better quality light.

    One last Kick:  Better daylighting makes us feel… well, better.

    Cool mojo from Molo Lighting

    I just thought this was kind of funky – obviously the the guy behind the camera agrees.
