Uptick in SUV/light truck sales alongside increase in big houses

Posted on by

Following up on a supposed McMansion comeback, Jordan Weissmann notes that SUV sales have also increased:

And how about those gas guzzlers? They’re on the rebound too. More than 51 percent of new autos sold today are light trucks, a category which includes SUVs. That’s right where we were in the Spring of 2007, though below the all-time peak of around 6 percent.

Now some caveats. The light truck category also includes increasingly popular crossover vehicles, which share some of the space and styling of SUVs, but are more fuel efficient. So the big cars being bought today aren’t quite the same as the big cars that were being bought yesterday. Meanwhile, mortgage credit is hard to come by, and perhaps as a result, the average new home buyer is a bit richer than before the crash, according to the NAHB’s data. That might partly explain our growing abodes, since wealthier families tend to buy larger homes. And as recession-scarred Millennials start entering the home market, there’s a chance they’ll start opting for smaller houses, as some real estate experts believe they will.

But sometimes it just feels like we never learn.

This builds on one of the most common critiques of McMansions: they are part of a package deal of excessive consumption that includes SUVs, bulk purchases at big box stores, and oversized food portions. There is little doubt that Americans consume a lot, particularly in comparison to many other nations, but it is not just about having a lot. This critique also is about being green and asking whether these levels of consumption can continue or could be extended to all that many other humans before resources run out. And, it often seems that there is a moral argument underlying this critique: should people have this size house and this size vehicle? This is why I think it would get really interesting if McMansions could be much greener (sustainable materials, low energy usage, less reliant on automobiles and built in denser areas) and SUVs could be more fuel efficient (is 40 mpg doable?).

Exposing Americans to passive houses

Posted on by

A Chicago Tribune article suggests more Americans would like passive houses if they knew about them:

The idea of passive house design isn’t new. It was first promoted in the early 1990s…

Torres Moskovitz estimates there may be 40,000 certified passive house buildings in the world, but probably fewer than 50 projects in the United States…

The stringent passive house — or Passivhaus — standards and the Passive House Planning Package software were developed by the Passive House Institute in Germany. The U.S.-based Passive House Institute is currently formulating its own standards. The PHPP software incorporates a designer’s calculations and helps design a passive house.

A passive house saves up to 90 percent of space heating costs and 75 percent of overall energy costs, though some European studies indicate the numbers may be even higher…

“People learning about it are so into it, maybe it becomes a bottoms-up approach, comes from the public and then the government has to react to our demand,” Torres Moskovitz says. “There’s definitely interest in the building community, but it has a way to go before everyone understands.”

I think a lot of Americans would be very interested in the cost savings of passive houses. But, they would want to know: if I pay more upfront for such a home, what is the payoff in reduced utility costs down the road? Even if there are significant savings, I imagine these houses are going to be part of a niche market for a long time as more people learn about them and builders learn to see them as profitable options. Perhaps passive houses need some sort of public relations push like a recent initiative regarding public housing?

One way to destroy the planet: “heat a McMansion”

Posted on by

Heating a McMansion is part of a list of 12 ways of “how to destroy the planet”:

The easiest way to waste extra energy in a large home is to keep the air conditioning and the heater on all the time, and adjust them both up until you’re comfortable. Space-heating makes up nearly half of the average home utility bill.

Heating water uses up more energy than anything other than heating air. For the profligate, that means long showers and always setting the washing machine for whites.

Perhaps this is why there is more interest in energy efficient homes or even net-zero energy homes. This argument would be even stronger if there were some numbers to compare larger and smaller homes. How much more energy does an average 3,000 square foot require compared to an average 1,800 square foot home? Or a 5,000 square foot house versus a 2,5000 square foot home?

One way around this would be to have home sellers include average utility bills as part of the documentation or listing of the property. Think of it like a MPG rating for a car – homeowners should also have the ability to assess the energy usage. Going further, home sellers might also list comparisons to other nearby homes. I’ve seen reports that using smart energy meters that give homeowners comparisons to their neighbors helps reduce usage so why not also make it part of the real estate process?

McMansion owners want “a front and rear entrance, a dining room, and a recreation room”

Posted on by

According to this description of McMansions, they offer suburban homeowners the basics:

When Sandy and Chris Ross were in Portland, Ore., they lived in a house built for those who buy large suburban dwellings.

“Our house was a McMansion, designed for most people who want a front and rear entrance, a dining room, and a recreation room,” says Chris Ross, a software engineer.

But the Rosses are not most people.

When they moved to Bryn Mawr, they wanted a house built to accommodate their family’s special needs, limited finances, and environmental awareness.

The main contrast developed here is between a McMansion and a custom-built home designed by an architect. McMansions provide the basics of a suburban home: a front and back door, some basic rooms, and plenty of space for living. In contrast, the home designed by an architect allowed the couple to have a kitchen that met their needs, a house that highlighted a notable Japanese maple in the front yard, and a good insulation and design that helps keep utility costs low.

Perhaps the bigger issue here is that most suburban homes are not built by architects nor are they really customized for their buyers. The article seems to suggest the custom home is desirable but a majority of homebuyers choose not to go this route. This particular story does not say how much this custom home cost. Additionally, a custom design might take longer and many homeowners may not feel equipped to help put together or desire a more customized home. Yet, a custom-designed home could allow more homeowners to really say their home reflects them.

Plans in the Chicago region to help mitigate future flooding

Posted on by

With the flooding that took place in the Chicago region in recent days, it is reasonable to ask what is being done to limit flooding in the future. Here is one answer from a regional expert:

Asked if costly and disruptive transportation chaos is inevitable, Josh Ellis, a stormwater expert with the Metropolitan Planning Council, offered some rays of hope.

“We can definitely do better. I’m not sure we’re willing to invest the amount of money needed to have an infrastructure that truly withstands a 100-year storm. When we built most of our infrastructure it was for a five- to 20-year storm standard.”

What’s slightly depressing is that current Metropolitan Water Reclamation District infrastructure and projects under way, including tunnels and reservoirs, will provide about 17 billion gallons of storage, Ellis calculates. Compare that to the 70 billion gallons or so that roiled Cook County alone in storms Wednesday and Thursday.

“Even when the Deep Tunnel is complete, the numbers don’t add up in our favor,” Ellis said. “We can do better, but I’m not sure we can ever solve this and have zero problems.”

So what can we do?

As individuals, it can come down to reducing the impermeable pavement on your property or cultivating a rain garden that holds stormwater temporarily.

On a wider level, it’s going to take expanding municipal stormwater systems, creating stream-side ponds to store rainfall and investing in green infrastructure, Ellis thinks.

“It’s about finding other places to put the water other than in big pipes … that’s what green infrastructure is,” he said. “It’s about finding ways for natural vegetation to prevent water from entering the storm system.”

Likely candidates for ad hoc stormwater storage include public entities with a lot of land — from schools with athletic fields to park districts.

The causes and consequences of flooding like this can be traced to human development. Critics of sprawl have noted for decades that flooding is one pernicious side effect: cover land with houses and asphalt and there is less place for water to go. Cover up natural wetlands and build close to waterways and this is going to happen every so often. Think of the concept of a retention pond; it is an admission that we have altered the natural landscape in such a way that we need to create a space for excess water to go.

I know some critics of sprawl would say the answer is to have less sprawl. Since this cat is out of the bag in many places in the United States, Ellis’ answers above are interesting: a combination of large-scale, regional projects would help as would more individual and municipal actions. Large projects like Deep Tunnel are impressive but they aren’t silver bullets. I’ve noticed more nearby communities have moved toward combining park land and floodplains. Thus, if flooding occurs, not many buildings are hurt and fewer people need to be evacuated.

This could also lead to broader questions: who is responsible for the flooding and its effects? Should individual homeowners bear the burden of protecting themselves and cleaning up? Should local communities? How about regional entities – how much power should they have to tackle such issues? This sort of problem requires coordination across many governmental bodies, calling for metropolitan approaches. It still strikes me as strange in the United States that individual homeowners may not know much at all about the flooding or water problems their property might have.

For a longer look at flooding and water issues in suburban sprawl, I highly recommend Adam Rome’s 2001 book The Bulldozer in the Countryside.

When the new McMansion next door blocks your solar panels

Posted on by

This is a twist on the issue of a McMansion being built next door: what if it blocks your solar panels?

What happens when the community wants terrace houses and a developer says ”no thanks, I’d prefer 20 storeys”? Which anonymous expert then knocks him back to 18 and compliments himself on his Solomonic even-handedness? Who prevents the new ”complying” McMansion next door from overshadowing your new solar panels? Who decides who gets listened to?

One complaint about teardowns or larger buildings constructed next door is that they can block sunlight. This can be a big deal, particularly in cities where really tall buildings could block sunlight for blocks. Indeed, many cities have restrictions on the footprint and the shadows large buildings can cast.

But, I’ve never seen the argument that it isn’t really about experiencing natural light and is more about solar panels. How many people are affected by this issue? Do homeowners have a right to access direct sunlight so they can power their dwellings? This sounds like a new area for regulations.

McMansions vs. trees in Bethesda, Maryland

Posted on by

Here is how the community of Bethesda, Maryland is planning to save trees from an onslaught of McMansions:

County Executive Isiah Leggett last year introduced a Tree Canopy Conservation bill that would force private property owners in small lots to pay a still-to-be-determined fee for lost canopy into a fund that Montgomery would then use to plant new trees.

Now, the County Council is wrangling with both sides to find a compromise.

Members of the building industry say the county shouldn’t legislate tree protection on private property, that they already avoid removing trees because of associated costs and that existing stormwater management requirements make protecting trees extremely difficult.

Some conservationists say the bill doesn’t go far enough, that replacing mature trees with new ones still takes away from the canopy, which everybody agrees is important for environmental and economic reasons.

Sounds like a typical suburban debate: should green interests or building/economic interests win out? The article doesn’t say this but I imagine there might be some old-timer versus newcomer aspects to this debate. If you have lived in the suburb for some time, trees are a good thing. They are not only green, they look better, suggest neighborhoods have stability, and contribute to higher housing values. If you are a builder or involved in real estate or want to move into places like Bethesda, you might want to pay less attention to trees and introduce new housing options.

One interesting note in the debate: there was some conversation about what percentage of tree canopy is desirable in a community. One pro-housing advocate suggested Bethesda already has more tree cover than much of the county. Just how much tree cover is necessary? Is a certain percentage related to housing values?

How a developer of big homes differentiates his homes from McMansions

Posted on by

Few builders are aiming to have their new big homes labeled McMansions. Here is how one developer describes how his new homes differ from McMansions:

According to brothers Taylor and Milton Chamberlin, the goal for the Georgian style homes is for them to be an alternative to “McMansions.”

“We really take our time to design the homes to fit in the neighborhood. We’re not builders that come in and put this huge McMansion in a small neighborhood where it doesn’t fit. That’s not what we do,” said Taylor. “All of this is really thought through and it’s really livable, usable space. It’s not those McMansions where you walk in and wonder, ‘What do you do in this room?’”

The base model runs around $1.4 million and features four bedrooms and 4.5 bathrooms, with the possibility of another bedroom and bathroom on an additional level. Costs will vary based on the different lot sizes and individual add-ons the purchasers want in their homes…

Another goal is to foster a 1950s sense of community among the owners of the nine properties, in which everybody knows and interacts with their neighbors. The homes will only be accessible via a private road and there will be a small fence around the subdivision…

The brothers noted The Barrett Companies’ effort toward green building and energy efficiency. From better insulation and caulking to installing appropriate outlets in the detached garages for plugging in an electric car, the Chamberlins believe small touches make their properties stand out.

These are big new homes that at first glance might fit several traits of McMansions. But, here is the argument the developer uses to say their homes are not McMansions:

1. The homes will fit the neighborhood. Critics argue McMansions, particularly teardowns, can disrupt the character of existing neighborhoods.

2. The home is not just about space; it is about well-designed and usable space. One argument about McMansions is that they provide lots of square footage but this is often contained in cavernous rooms or in poor layouts that are difficult to utilize in day-to-day life.

3. They are hoping to promote a community atmosphere in their small development. I wonder if this is primarily a function of size; the fenced-in neighborhood with a private road will only contain nine homes.

4. These homes will be greener than normal big homes. McMansions are often said to about excessive consumption and part of sprawl.

5. There will be a consistent design scheme with Georgian architecture and detached garages on the private road away from the streets surrounding the neighborhood. McMansions are criticized for mixing architectural styles.

In the end, I wonder if a majority of buyers and critics would think these reasons are enough to separate these homes from McMansions. These are still big homes in the midst of suburban neighborhoods. They may be more consistent and be less mass-produced but are they different enough?

Los Angeles “the first major city in the world to synchronize all of its traffic signals”

Posted on by

Los Angeles, famous for its roads and highways, is now leading the world in having all synchronized traffic lights.

Mayor Antonio Villaraigosa was expected to flip the switch on Tuesday on a final traffic intersection system that will result in the synchronization of all of nearly 4,400 traffic signals in Los Angeles.

KNX 1070?s Pete Demetriou reports L.A. is about to become the first major city in the world to synchronize all of its traffic signals…

Officials said the completion of this project will increase travel speeds by 16 percent and reduces travel times by 12 percent…

Signal synchronization also dramatically reduces carbon emissions by 1 million metric tons a year due to less idling at intersections, according to officials.

Less congestion and greener? Sounds like a win-win.

It would be interesting to know the final costs and logistics involved from the full project. The article suggests this project was part of the planning for the 1984 Summer Olympics but was not completed until this week. If this is such a great benefit for the city, what is stopping other cities from doing the same thing?

First passive house in Illinois completed

Posted on by

The Chicago Tribune profiled a River Forest home that is the first in Illinois to be certified as a passive house:

To earn certification, the house had to pass a third-party audit that included a blower-door test to detect air leaks, a visual inspection to make sure specified products were used, and an air-flow test of the ventilation system to ensure that incoming and outgoing air was balanced.

Including the finished basement, the house has 3,800 square feet plus a detached, two-car garage. That includes three upstairs bedrooms, an open living area plus in-law suite for Corinna’s parents on the main level and a recreational room on the lower level.

The first thing a visitor notices about the Lemas’ house is its 18-inch-thick exterior walls. They contain the key to keeping the house airtight — Logix insulated concrete forms, which are Lego-like panels of concrete and foam. Outside of that is a 2-inch rigid foam layer, an air cavity and SmartSide engineered wood siding…

The Lemas figure they spent about $175 per square foot on the house, including site work and demolition of the house that used to occupy the property. That is on par with custom residences that are not passive houses, said Bassett-Dilley.

Interesting article though I wish more time was spent on the process of building the home, such as passing inspections and hearing from neighbors, rather than the particular pieces that went into the home.

While this is the first passive home in Illinois, I wonder what the resale market for such homes might look like in the near future. Is there a premium homesellers can ask for since such homes are rare?

Also, I have read a number of articles about such homes but haven’t really seen anyone discuss possible downsides. What happens if the air exchanger, needed to bring in air since the house is so sealed, goes out? Are there longer-term issues that come up amongst homeowners in such houses?
