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.

A friend recently recommended this book:

Good House Cheap House - An Adventure in Creating and Extraordinary Home at an Everyday Price by Kira Obolensky.

The main premise of the book is that you can build your dream house for below market rate prices through creativity, salvaged materials, and hard work.  I will start by saying that I like the idea and I really like a most of the houses that she features. I also agree with Kira that the architect should not be eliminated as a cost saving measure. But now I will pick apart the strategies that she puts forward.

1) Salvaged materials – Generally this is not a viable or significant cost saving measure for most people. It is hard to find and store quantities of building materials. Using used windows doesn’t make sense in most climates because used windows are mostly not up to current energy efficiency standards. Using used framing materials often requires that they be re-certified to prove they can still perform.  Additionally, Labor costs in the United States are usually a bigger share of the budget than the materials….so it doesn’t make sense from a financial standpoint to have paid labor removing nails and cleaning up salvaged materials.  That said, if you do have a place to store materials out of the weather and access to good salvage yards, craigslist, and other places to buy used materials, money can be saved. There is often also character and charm in using salvaged materials..and of course it can be more environmentally sound. The same is true of saving parts of an old building rather than tearing it down and starting from scratch. Unfortunately, it is often cheaper to start from scratch.

2) Creativity – Kira shows many examples of ingenuity and unconventional uses of materials. Honestly, for most people with a hired contractor, I can’t imagine that this saves any money. The idea would have to be communicated from architect to client to builder, or from client to architect to builder or maybe just from client to builder and this often is a challenge.  Frequently new creative ideas scare builders who have to put a price tag on things ahead of time.  Many of the houses in Kira’s book are architects’ own houses. Its much easier to be creative on your own house. You can experiment and don’t have to spend time creating drawings, models, or other tools to convince the client of the idea.  These architects probably did some of the building themselves, eliminating communication altogether.  That said, much of the construction budget goes to finish materials. If you like the aesthetic of plywood as a finish floor or various sheet goods rather than tile for your shower and bathroom floor, curtains instead of doors for the shower and some closets, then you can save money.

It is wonderful to create something beautiful through creative use of basic materials. In my mind this is way cooler than making something beautiful by spending money on expensive tiles, carpets, and other architectural elements.

3) Hard work –  In my opinion, this is the only sure winner, but it also has to be smart work.  Experienced builders and architects and engineers are often more efficient and have tricks of the trade. Doing your own work, design or construction, can sometimes lead to disappointing results.  The hardwork that makes the most sense in my opinion is spending the time to carefully select your architect and builder, spending the time to have your needs and desires and budget thought through, assisting the architect where possible and being available and giving schematic plans sufficient thought and consideration and getting preliminary pricing before moving along to the more detailed construction documents. It is often a good idea to pick a builder early on so the architect and builder can work together for an efficient collaboration. During construction there is plenty to do. Some builders are open to clients helping with the work, others typically bigger companies, want no part of this.  I have had several projects where a small builder was happy to have the owner operate as a carpenter’s assistant. This is a great way to learn and get your hands dirty while having an expert on hand to guide the project. Home owners also frequently help with clean up and dump runs – labor intensive and low skilled parts of the job. Painting is often done by the home owners, but it is often more efficient to paint before finish electrical and plumbing, so it might be inconvenient for the contractor to wait while the homeowner does their own painting. The most important thing that a homeowner can do to make the job more efficient is to be available and spend the time to make decisions as quickly as possible. If every door knob has not been selected prior to construction with the architect, these things will have to be selected during construction. There are a lot of small decisions like this and it is crucial that they don’t cause delays.  It is even more important that you don’t change your mind about certain decisions. changing things late in the game can be very expensive.  Beyond making decisions, keeping your eye on things is always helpful. Even an untrained eye can detect issues and help things go more smoothly.

4) Simplicity - A cost saving measure that Kira does not mention is simplicity. For example: Most kitchens these days have recessed lights, under-cabinet lights and a decorative light in the middle of the room. If you have high enough ceilings to make it work, stick with one big light in the middle of the room. (if your ceilings are not high, you might not get enough light on the work surfaces.)  Every switch and fixture costs money. Complicated roof lines can be very expensive in labor and materials.

5) Lifecycle costs – It is also important to consider the lifetime costs of the building. Incandescent bulbs might be cheaper, but LED bulbs will save you money in the long run. Durable materials will last longer. Money spent on extra insulation will usually save money down the road.

I’ve been following this blog of a color consultant & interior designer in part out of fascination with someone so different from myself, but also because she has some real tidbits of wisdom. Read the post linked above for her explanation of what is good about this room below.

Evelyn Grace Academy by Zaha Hadid Architects

Dezeen magazine published this article about new policies in the UK mandating more utilitarian designs for new schools to be built in upcoming years.  The Royal Institute of British Architects (RIBA) has responded to the new rules with concerns that many of the guidelines will yield short-term savings at the expense of long-term goals.  I haven’t yet thoroughly read the regulations, but they do seem a bit overly rigid. The article contains a kind of depressing, misguided quote from education secretary Michael Gove:  ”We won’t be getting Richard Rogers to design your school, we won’t be getting any award-winning architects to design it, because no one in this room is here to make architects richer.”  As if there was a big problem of architects getting rich at the expense of the schools. They might be right to hirer fewer flashy star architects and I agree that schools, and buildings in general need to be sure to address practical concerns in addition to pushing the envelope with creativity, but it seems that they likely have gone too far with their guidelines.

My Dad just sent me this interview of Rahul Mehrotra, an architect practicing in Mumbai, India . He presents some of his ways of helping to connect society, “soften thresholds,” and bridge the gap between rich an poor in a very economically stratified place. In case you don’t have time to read the article, here is one excerpt from the interview that I found meaningful:

“This idea—how architecture can deepen social divides, depending on how it is used—is a major theme in your work, and obviously something you care deeply about. Do you ever have a private client who wants to build a very ostentatious house? How do you handle that?

I try to steer my wealthy clients toward “introverted worlds”—marble floors, nice fixtures. Ostentation on the inside rather than the outside. Polarization occurs when wealth is flaunted, and architecture can get co-opted in that process.”

My friend Amanda installed this Marmoleum floor in her laundry room. I think the color choice is great in this small, mostly white room. It might be a bit busy in a bigger room with more colors, objects, and activity. Marmoleum is a great product – It is old fashioned linoleum made from “linseed oil, rosins, wood flour, jute and ecologically responsible pigments.”  It comes in a wonderful array of colors…most are subtly speckled so dirt and crumbs and scratches don’t show so much.

The internet seems to like our small studio. I have found many repostings of Lenny’s photos, and commentary about the little studio. Most of them seem to have just nabbed and revised slightly the written content from Dwell or the Washington Post, but here are a few that are more original:

House Vote

Pintarest

Arcidec

House Vote has also posted a few other photos of my projects:

I received this hefty book for Christmas from my dad.  It contains a lot of great photos of the city I grew up near. Enclosed in the pages of the book was this New Yorker article about the book and its forward written by Elmore Leonard, also a native of suburban Detroit.  It is mentioned in the article and forward that “Julia believes it should be preserved and appreciated any way it is, not restored.”  Urban decay is beautiful, I agree, but honestly it seems like an insensitive statement from a resident of Bloomfield Hills. You could call her a poverty tourist. I know for a fact that many Detroiters are annoyed by all the hipsters from Europe who come in droves to photograph the urban blight.  But in some ways I am inclined to agree with the author.  (I too have the privilege of viewing the city from afar and on occasional visits home to another affluent suburb.) The people of Detroit deserve our compassion and it is sad to see some truly beautiful old buildings fall into unsalvagable disrepair, but at this point it might not be all bad to allow the city to slowly return to nature.

The New Yorker Article ends with reference to Elmore Leonard’s teasing attention to the origin of the holes in Julia Taubman’s jeans.

Michelle Bachmann's house with "a grand manor roof" and "European flavor"

Gingrich's "Mansionette"

Santorum House: "a big rectangular box with holes punched in it for windows. It doesn’t have much to say. Need I say more?”

The New York Times ran this article recently about the homes of the Republican presidential candidates. The review, informed by “interior designers and  design psychologists” (no architects) is generally unfavorable. They make fun of Newt Gingrich’s extensive use of mirrors and Huntsman’s pink love seat with yellow bows. Bachmann’s complex roofline is rather atrocious (no mention of the maintenance issues with such a roof,) and Santorum’s more simple house is called boxy with small punched windows.  The houses are all quite big… mostly around 5500 square feet. One designer who commented in the article said that he’d call them McMansions, but that would give McDonalds a bad name. Wow. That is saying a lot. None of them appear to be designed by architects that were given much latitude, but most of the candidates appear to have dropped some cash on interior designers.  The houses all scream “I am a traditionalist,” according to design psychologists that were consulted.  Manicured green lawns and brick or stone are present in all.

Uh Oh. What would they say about my parent’s house, (the house were I grew up)? My dad took off the fake shutters at least….and it does have industrial chic concrete window sills. The windows are true divided lites, by the way, and my folks hired a local artist to make some stained glass windows for either side of and above the front door…Its not so big, but it is brick veneer with a green lawn and small punched windows.

Not a Republican house though

There is no discussion in the Times article about solar orientation or energy efficiency. There is no mention of simplicity, elegance, or economy. Creativity does not make an appearance, (except in Newt’s whimsical topiary.)

Perhaps the candidates can learn a bit from Ice Cube.

At lunch today I went with Guillaume Canivet  to visit the Simpatico Homes prototype modular house in Emeryville.  Seth Krubriner, the owner of the house explained the design and construction process from start to finish. The modules were constructed in San Jose by Eco Offsite.  Swatt Architects was also involved. This sounds like a lot of cooks in the kitchen…..so I am curious how the collaboration worked.  Seth gave a very interesting and honest presentation of the benefits and drawbacks of modular construction compared to conventional site built. His house actually has site built pieces added onto the modules.

To me, it seems that the best part of choosing a modular system over conventional is that you are limited by the modular system. There are fewer choices and therefore the design process is simpler. Just like a restaurant with a short menu, the specialization and simplification often yields a better product.

Without a good understanding of the system and a willingness to work with it and accommodate it in the design, a modular house might not be any less expensive than a conventionally built house, and could easily cost more, especially if the factory was not very close to the site.

In Seth’s house the joints between the modules are accentuated and celebrated. (you can see one of the joints, a black reglet, in the photo above.) This is an example of how the design should accommodate the system. If Seth were to try for a more traditional aesthetic he would have lost some of the savings.

This same simplification and cost savings could be achieved by an architect who presented a limited pallet of materials and a select contractor and offered to deliver a very specific product. Not a bad idea.

I recently helped my friend Rain assess the architectural merits of a house she wanted to buy. She also hired a home inspector who brought this seismic brace to my attention. It was his opinion that this is a poor design because in a big quake it concentrates the force and ends up busting through the floor rather than providing lateral stability.
