So Long, Frank Lloyd Wright

 

 

     Once a month or so Marie and I have dinner with a group of old friends, all of whom happen to be particularly interested in theater and other creative arts. The subject of architecture in general and Frank Lloyd Wright in particular popped up during one such recent gathering over Indian food.  Our friends burbled enthusiastically about their past visits to various Wright buildings and how beautiful they are. 

 

     I got into trouble when…

The Ductopus or the Centipede - Which HVAC Duct System Is Better?

I've been thinking lately that I might be in danger of losing all my friends in the HVAC business because I've been a bit heavy on showing examples of what they get wrong but not so good at showing what they do well. If you read my article… Continue

Looking forward to the day smart grid dies

The title of this blog might strike you as kind of weird, especially this week. After all, the Electric Power Research Institute made the news with a study showing that smart grid is going to be far bigger than we first thought.

Smart grid in simplest terms brings to the electrical grid the digital intelligence of computers and the Internet. Just seven years ago EPRI expected smartening the grid to cost $165 billion.  But its new…

Policing DIY.com - stop bad building advice at the source

I am always looking for good information and resources to share with customers about building science.  I really want to engage people to understand building science, and empower them to work on their own homes more.  Sometimes, the task of deconstructing misinformation is bigger than I realize...

 

Cruizing the internet this afternoon, seeking recources for some customers who intend to take on their own basment remodel.  I have found lots of good DIY guides on the DIY Network,…

Design, circa 1997

At a job site meeting this past week, our newest design clients handed Abe a small pile of dog-eared, marked-up “inspiration” magazines. They contained pictures and ideas collected by the homeowners, and demonstrated their affection for clean lines, neutral colors, and a judicious use of space. …

How the poor may boost clean tech

It’s not surprising that a company liked Greenhouse Holdings, which builds eco-friendly infrastructure, would have a thriving California-based operation.  But as John Galt, the company’s executive chairman and founder, told Renewable Energy World magazine, the company is not just focusing on wealthy…

Energy efficiency absorbs water

Efforts have been underway for decades to conserve both energy and water, but never in concert. This is unfortunate because energy uses a lot of water and water uses a lot of energy.

Two leading conservation organizations have set out to bring the efforts together. The American Council for an Energy-Efficient Economy and the Alliance for Water Efficiency this week published a white paper that describes the co-dependence of water and energy resources, and outlines strategies to use…

The Ductless Mini-Split Heat Pump's Big Brother - CITY MULTI

Energy efficiency and the annoying guy next door

Who would have thought backyards would cause so much trouble for the North American energy industry? First came the NIMBYs, the not-in-my-backyard protesters who block power projects from being built near them. And now we have the GIMBBYs – the give-me-a-bigger-backyard homeowners who are unwittingly getting in the way of energy efficiency.

GIMBBYs aren’t worried about seeing wind turbines or transmission lines from their backyards as are the NIMBYs. It’s the guy next store that they…

Energy Efficient Appliances - Add Appeal To Your Home Listing

If you can afford it, go for an Energy Star rated appliance. You'll save in energy costs in the long run and if you ever decide to sell your home, it may have greater appeal.



Energy efficient appliances are of great interest to home buyers. First and foremost, these appliances save energy, which translates into lower utility bills.



Additionally, eco-friendly buyers appreciate the efforts made by the seller.

Three Simple Acts That Can Make A Difference

 

This past April 22nd was Earth Day 2011, and it's official theme was A Billion Acts of Green. The basic idea is that, if at least a billion of us each pledged to perform some relatively simple “act of green”, we’d all be that much closer to a greener, more sustainable world. Here are examples of three simple, relatively low cost (lightweight, if you…

No Carts Before Horses - Design for Energy Efficiency Early

My recent visit to Savannah for the USGBC's green product expo charged up my historic preservation bug and got me to thinking about how to apply building science to historic buildings.

What Tokyo Must Do



Few countries have been dealt such a tragic combination of natural and manmade disasters as Japan. The part of the disaster that I understand is the shortage of electricity. I wrote a book, Saving Electricity in a Hurry, in 2005 while working at the International Energy Agency.1 In the book, I explained the measures that a government must take in order to quickly reduce electricity demand while protecting…

Energy efficiency and Weight Watchers

We’ve been hearing for years that the energy efficiency industry needs to find its equivalent to the cell phone. These days industry folks refer to it as the ‘killer app,” the revolutionary product or service that consumers can’t resist.

But lately, partly because I’m dieting, I’ve been thinking what energy efficiency really needs is something akin to a Weight Watchers dessert.

Let me explain…

When you absolutely, positively NEED to get efficient overnight!

Every once in a while, we have an experience that completely crumbles some long-standing preconceived notion, and this week I’m pleased to share my revelation with you. I’ve just returned from a week-long trip to Cuba with a group of twenty other energy professionals sponsored by Solar Energy International andGlobal Exchange. The purpose of the trip was to explore…

Willowside Rd., Day 14

John and Jane Doe's report is basically written. I have a template that I use that has been slowly built and improved over the past projects. It's a fine start but still requires a fair amount of custom writing, since each house has enough unique issues that need to be addressed.  There's report software out there such as Recurve's, EAI, or BizEE, but none have that personal touch that comes from a written report.  So here's some items from the report:

100 Homes and Counting...

On April 15, 2011, Homes for Our Troops, a national nonprofit, nonpartisan organization founded in 2004 that's dedicated to helping veterans who have returned home from combat with serious disabilities and injuries since September 11, 2001, kicked off the build of its 101st home in Fredericksburg, Virginia. Homes for Our Troops is building this particular home (see photo) for U.S. Army Sergeant Jude Recendez who lost both of his… Continue

Willowside Rd., Day 10, part 2

OK, I'm back from getting the dimensions of Doe's house, enter all the information into EnergyPro, and do an initial calculation. It looks like the house as it is has a HERS of 147, which means that the model predicts that it will use about one and a half times as much energy as a 'reference home', which is this exact same home if it was built to today's energy code requirements and has by definition a HERS of 100. 147 is not too bad but way above what we want. Let's see if we can get it below… Continue
