I'm bidding a new house in Mass. The builder told me to include the new energy codes that became effective as of July 1st. Anybody aware of what he is talking about?
I recommend Halogen spots 4" recessed and dimmable over any permanent fixtures, offset to TV location, or even have two on another switch to backlight the TV viewing area. 4" can also be used in front of built in structures like book cases, or owner desired accented walls.
Well let's all learn something is it 50% of wattage used or just 50% of the lights are energy effiecient?
This is a good question. I had heard a few things about this but as usual no info form any government agency. One thing I did hear was that you can no longer run romex through insulated stud bays horizontally.
I'll see if I can get more info.
Nothing I have seen in this new code gives any guidance beyond "50% of lamps need to be energy effecient". So it make me wonder... If I install a chandelier with 50 bulbs, and make them cfl type, and all other fixture bulbs total 50 more (for a grand total of 100 lamps) then I have met the 50% effecient lamp requirement?

Looks like the energy codes are based on the IEEC. If anybody has any info on those chime in please!
Also there is a stricter code cities and towns can adopt called the "Stretch energy codes"
It is important to know what towns those are before you bid a project. A quick look shows, big surprise, Cambridge, Lexington, Newton have all adopted said code.

In CA, it has to be 50% of the installed wattage, which is based on the rating of the fixture, so if it can take a 100w bulb it doesn't matter if you install a 60w bulb, 50 watts must be high efficacy and screw in CFL's do not qualify. The high efficacy fixtures may not contain a medium base socket.
At least you know what your states rules are. I can't find anything that spells out the requirements on Mass.
BTW, how the heck to you light a home in your state? I can see flourescents in closets and maybe hallways where you don't normally dim the light. What do you do everywhere else?
The 50% rule in CA is for kitchens. You have to match every watt of low efficiency lighting with 1 watt of high efficiency light.
In other rooms you can have incandescent if it is either on a dimmer or "vacancy" sensor depending on what type of room.
What are you installing in the kitchen to get 50% of lamps to be effecient? Are you having to use LED (very expensive) or flourescent recess or something else?
