Rosenfeld Affect


Art Rosenfled

I was impressed by this little tidbit in a recent Title 24 Seminar I attended.  Sometimes the California energy codes seem behind the technology and sometimes overly technical and expensive, requiring expensive gadgets and fixtures, but look at the energy savings!!!

Here is the whole story from the California Energy Commission.

Aalto’s summer house, Muuratsalo, 1953 – brick experiments

I love bricks. The scale of a brick to fit in a human hand allows you to imagine the wall being built one brick at a time. I probably read that somewhere rather than invented it myself, but it’s right. Bricks can also create nice patterns. This photo is of a wall of Alvar Aalto’s summer house on Muuratsalo and maybe was a test palate for different brick options.

I looked up this project up in my one Aalto book, Alvar Aalto by Richard Weston, 1995.  Weston has several pages on these “brick experiments”

“The brickwork is also painted white externally, while inside the courtyard the brick and tile experiments create a rich patchwork-quilt on the walls and floor, which suggest by turn De Stijl-like reliefs, or old walls with redundant door and window openings bricked up and patched over time. The experiments were as much aesthetic as technical: we are in the world of metaphor again , for what are these walls if not imitations of ‘ruins’ – past, or perhaps to come? Is this tiny piazzetta, the atrium of a Pompeian patrician’s dwelling, or the (de)relict room of a large, old house, which has lost its roof and been recolonized as a picturesque courtyard? All these possibilities come to mind: the image is too general to be pinned down to a specific interpretation – it would lapse into kitsch otherwise – and can still be contemplated simply as an abstract collage. Memories of Pompeiana probably played their part. As did those of Italian piazzas. I like to think Aalto intended the walls to be seen as the arch-empiricist’s ironic commentary on the fate of the strict geometric compositions then coming into favor in Finland under the influence of the arch -theorist Aulis Blomstedt, with his pythagorean fascination for number and proportion on the basis of beauty. ” Pg 119-121

There are several more paragraphs of discussion of the meaning of this brickwork in Weston’s book. I think I will let you read the book rather than transcribe it here.

thermal image of tight house

I stole this photo from the website of Fabrica718. It is an image taken with an infrared camera of a block of Brooklyn brownstones. The blue one is the one they remodelled….blue because its envelope is so well insulated that very little heat is escaping. Pretty cool. I’m not sure why most of the other houses have blue second and third story windows. I can’t imagine that the whole block has been upgraded to triple pane. Any ideas?

Well's underground office entry

Appraisals make me grumpy. It seems brutal to reduce the value of a house to square footage, numbers of bedrooms, and whether the bathroom floor has tile. There are so many intangibles that contribute to the value of a house. For example the two large trees in front of my house that shade my bedroom in the summer with their dense greenery then turn bright orange yellow and red in the fall.  Of course there has to be some way to quantify a house’s worth for banks.

One guideline that seems pretty silly is the rule that square footage that is even slightly below grade is not counted as square footage.  This realestate agent’s article has some funny comments.  One guy actually seems to have hired a bulldozer to unearth his house so that he could qualify for a loan. Another homeowner determined that he has no square footage because his entire house is dug into the earth.

I thought of one of the inspirations of my youth, Malcolm Wells. He was an architect in Massachusetts who built most of his buildings underground.   Here are some of his words about this way of building (from his website):

“…By letting our structure hog all the sunlight wherever we go, we stamp out much of the natural riches of our land. Weather is not kind to building materials. They need to be protected by a blanket of earth. Otherwise, ice cracks the freeways, water rusts bridge structures, floods rage because water cannot soak into impervious ground….”

“…We live in an era of glitzy buildings and trophy houses: big, ugly, show-off monsters that stand—or I should say stomp—on land stripped bare by the construction work and replanted with toxic green lawns. If the buildings could talk they would be speechless with embarrassment, but most of us see nothing wrong with them, and would, given the opportunity, build others like them, for few of us realize that  there’s a gentler way to buildIt’s called underground.”

Here are some nice pictures of one of his houses

My client would like a surface mounted track light over her bathroom vanity.  I wanted certainty that code would allow a fixture rated only for dry locations in a bathroom.  I found this article written by Mark Ode, a staff engineering associate at Underwriters Laboratory Inc on the website for the UL Company.

According to Mark, a dry location luminaire must be installed in a location that is not normally subjected to dampness but may be subjected to temporary dampness. With the proper ventilation, above a bathroom vanity fits this qualification.  Inside the shower of course, where water can easily splash on a fixture, a fixture must be wet rated.

His article also explains the difference between wet, damp, and dry UL ratings, as well as a few less common ratings for light fixtures.

Yesterday I attended this lighting showcase at the Pacific Energy Center. Most of the lights on display were LED technology. Here are a few highlights:

The building energy code for California is getting stricter in January 2014 and the new rules have been published.

The real goal is for all new homes to be net zero energy by 2020.

One of the biggest hopes for energy savings is LED lights, and the CEC is cracking down on the industry demanding tighter tolerances and standards so that consumers can trust that they are getting the amount and color of light and the longevity that they are paying for.

I just got home from a presentation of some of the latest in LED lighting technology by Param Electric at Laner Electric Supply. I learned a few new tricks and I have some of their product recommendations to share.

1) You can add a current limiter to a track lighting system so that it can pass inspection in a kitchen where lights are required to be high efficacy

2) This one isn’t strictly for LED lights: MR16 fixtures need filters to diffuse the light and eliminate spotty wallwashing

3) The amazing new Cree “A Lamp” only dims to 40%. The new Title 24 for 2014 will require it to dim to 15%, so hopefully Cree will be able to make that happen. These sorts of LED bulbs that can screw into traditional sockets are a great and simple solution for energy savings without throwing out the whole fixture. Beware that overheating is a problem for these bulbs. Many cannot be installed in enclosed fixtures and some cannot be installed facing up. Most are directional, which can be a good thing, but doesn’t work so well in situations where you want light to shine up and down and all around.

3.5) I have used Cree recessed LED lights myself for at least the last 5 years with success, but learned from these specialists that Cree has good quality control and makes the lamps for many of the more high end LED fixture manufacturers. Cree itself keeps it simple and is able to produce basic recessed lights for a very affordable price. If you want something with more bells and whistles you will need to go to their competitors, Juno, Halo, Tech lighting and more. Many of their more expensive competitors are using Cree lamps in their own products.

4) Creative Lighting Systems makes a 2″ diameter recessed light that puts out 800 lumens for 11 watts. (Laner sells the whole package for about $220, the 4″ version is about $160) You can get lenses to change the lighting effect/ beam spread. According to Param, the color of CSL LED lights is not well controlled. You might get one where the color is off, otherwise they make great lights.

5) The color in Kelvins of LED light varies a lot. There has been poor regulation of this standard, but this is one of the things that the regulators are cracking down on. Soon the LED manufacturers will be held to a higher standard of accuracy. Read this for more info on color temperature in lighting.

6) Tech Lighting makes very high quality recessed lights and they are the only option if you need something that puts out a lot of lumens.

7) Diode LED makes very user-friendly strip lighting. A remote driver is required, but it can be far away and it isn’t very big. I have one of these strip lights over the door to my office. I love it so far…been about 3 years.

8) Max Light and Phillips Color Kinetics both make some good self-contained LED fixtures for undercabinet, closet, cove etc that do not need remote drivers.

9) RAB makes some great exterior LED fixtures. I can vouch for these myself.
