Interview with GreenPoint Rater John Eckstein

Posted on 23. Sep, 2009 by Rebecca Firestone.

A few months ago, we had the pleasure of working with a GreenPoint rater on one of our recent Title 24 consulting projects. John Eckstein is a building professional with expertise in both home energy performance, and indoor air quality, particularly mold investigation. Since GreenPoint rating is still relatively new, we asked him what is involved in working with, or becoming, a GreenPoint rater.

Passivhaus, Passive Houses, and Your Carbon Footprint

Posted on 27. Aug, 2009 by Alan Huguenot, CEPE.

The Passive House Institute in Germany  has improved upon American ideas from the 1970s and re-branded it as PASSIVHAUS. Superinsulated homes have been built in many locations in the U.S. over the last 30 years, as Dan Hagen P.E. describes in his letter on the ASHRAE web site.

Passive houses use significantly less energy than do existing or new conventional residences. In fact, they use so little heating energy that a conventional heating and cooling system is mostly unnecessary. The house stays warm by recycling heat that is already being generated by internal sources – lighting fixtures, stoves, toasters, dryers.

Home Systems Integration Offers Visibility and Control Over Energy Use

Posted on 24. Jul, 2009 by Rebecca Firestone.

Jay Bakaler of Ultimate Control was very severe with me. “Don’t call it home automation!” he said. “Home automation got a bad name in the 80s and 90s, and now when people hear that word, they all run for the hills. What we do is systems integration, also called whole-house control systems. It’s more about choosing the right standalone systems and carefully and thoughtfully putting them together.” [...]

Net Zero Homes in Northern California

Posted on 20. Jul, 2009 by Rebecca Firestone.

Net zero energy buildings produce more energy than they consume, and while they can function autonomously from the grid, they aren’t necessarily disconnected from it – they can use the connection to sell excess energy back to the utility companies. Sounds too good to be true? Can you really get paid to solarize your home? Well, David Knight from the Monterey Energy Group just might be able to help you get there. His take as an experienced engineer on which of these technologies really makes sense should carry a lot of weight with both designers and their clients.

Klopf Architecture Reflects an Eichler Sensibility in New Energy-Efficient Home

Posted on 09. Jul, 2009 by Rebecca Firestone.

When I first ran the numbers on the new Title 24 project from Klopf Architecture, the numbers were so high – 50% over compliance – that I immediately assumed that I had made a mistake somewhere in the calculations. After an internal review, however, we realized that it really was one of the most efficient projects we had ever taken through the energy compliance process. How did they do it?

Can Energy-Efficient Lighting Be Beautiful?

Posted on 22. Jun, 2009 by Rebecca Firestone.

Office workers and high school students from 30 years ago remember the terrible lighting from that era – the greenish, corpselike complexions, the blurred vision, the flicker-induced migraines, the depression, even the supposed vitamin deficiencies from the limited spectrum of those old fluorescent tubes. Nothing says “factory farming” quite like that old whitish glare. And the buzzing noise they made… the list of physiological, psychological, and aesthetic impacts goes on and on.

Now, there are all kinds of “full-spectrum” lights out there, low-voltage halogens, and newer generations of fluorescents like the compact bulbs, that look a lot better and definitely save over incandescents. But qualitatively, which ones are really competitive for high-end residential design when appearance and aesthetics are paramount? We asked Ed Cansino, a lighting designer with over 25 years of experience, and here is what he said.

Interview with Green Builder Jeff King

Posted on 18. Jun, 2009 by Rebecca Firestone.

Last week and today, Mark English and I spoke with Jeff King, president of Jeff King & Company, about what building green really means. Some of his answers surprised us. To paraphrase:

“Finishes are only skin deep, but infrastructure is to the bone.” – Rebecca

Fuel Cells Offer Clean-Burning and Efficient Heat and Power

Posted on 16. Jun, 2009 by Rebecca Firestone.

We’ve all heard about fuel cells by now – they’re in electric cars, among other places. Here is an interview with Bill Sproull and Katrina Veerman of ClearEdge Power, a startup based in Portland, Oregon, with offices opening in California. ClearEdge has developed a modular fuel-cell product that can provide heat and power for almost any size structure, from a private home to a large commercial building.

“This is not a pie in the sky… this is practical, everyday stuff.” – Mark English, AIA

Slab Edge Insulation and Termites: A Solution

Posted on 13. Jun, 2009 by Alan Huguenot, CEPE.

Interview with Bill Michelson, CEPE, San Joaquin County Building Inspector from November 2008

In GCP No.12, we had published an explanation of the slab edge insulation requirements which are required by Title 24 when specifying radiant heated floor slabs. We illustrated that prior discussion with examples of slab edge insulation as shown in the 2005 Residential Compliance Manual.

However, being practicing architects and architectural engineers ourselves, we also push projects through permitting, construction and final inspections, which allow us firsthand knowledge of how Title 24 requirements interface with building inspection requirements. So, after discussing those slab insulation details last week with one of our colleagues, Bill Michelson, CEPE who is a San Joaquin County Building Inspector, he mentioned one glitch in those Title 24’s details which Building Inspectors find troublesome in zones where termites are a problem, but he also recommended a solution, and here is that interview.
