California Demands Solar In New Housing – Only 49 to go

I have been at a loss for words for the last month. Things are going so well. I know Dotard is still President and many things are seriously messed up. But on the alternative energy front things just keep getting better and better. Don Blankenship actually made a fool out of himself and lost a primary vote for the Senate in West Virginia. Next week I may even get to report that Yucca Mountain is open for business. But for now, California hits one out of the park.

California regulators approve mandate for solar panels on new houses

California regulators on Wednesday mandated that all newly built single family houses have solar panels, part of the state’s aggressive push to combat climate change.

The California Energy Commission voted 5-0 to approve the measure, which also applies to multifamily buildings of three stories or fewer. The mandate is set to take effect in 2020 and does not need the approval of the Legislature.

The requirement is expected to save consumers money in the long run through reduced utility bills, but also make a new house more expensive to purchase at a time many families already struggle to afford a mortgage.

In addition to the solar mandate, the commission approved new insulation and air filter requirements for newly built homes. In all, the new residential requirements are expected to make a single-family house $9,500 more expensive to build on average, but save $19,000 in reduced utility bills over a 30-year period, according to the Energy Commission.

UIS Has A New Student Union – It is Green as all get out

I am a graduate of Sangamon State University. What is now University of Illinois Springfield. They just build a Student Union and I am so proud of it. It could be LEED certified and it is student centered. Our Student Union was in a temporary building 0n the temporary campus “down the hill”. This is just so cool.

Strategic Design of the UIS Student Union

This is the part I like:

Environmentally Excellent

UIS is seeking a LEED Gold certificate (Leadership in Energy & Environmental Design, awarded by the U.S. Green Building Council), both for the sake of the environment and in order to take advantage of energy saving measures. For this reason, the building will have a green, or “living,” roof with vegetation and a growing medium over a sloped membrane. This roof will provide insulation, help to lower air temperatures, and last much longer than other roofs—50 to 60 years rather than the 20 to 30 years most roofs last. The vegetation will most likely include wildflowers that will change throughout the growing season, adding to the building’s beauty.

To reduce storm runoff and eliminate water irrigation, the Student Union will have a rainwater reclamation system that takes advantage of the roof’s slope. Also in consideration of LEED approvals, lighting will be designed to meet the USGBC’s very stringent requirements.

Home Energy Efficiency – From a Realtor’s perspective

I agreed to publish this here because it is such a different perspective then the one I have or CES has. We tend to blame builders for not just serving up top notch energy efficient residences. Then there is the issue of retrofitting. As always this is no endorsement of Ryan or his Real Estate firm. Believe me I have no intention of buying a home in Alaska.

 /
Now, a “green home” really isn’t all that green when observed on its own, but the fact
remains that most of new construction and existing homes are going to be detached
single-family residences. This means that we need to do the best we can with the hand we
have been dealt, and that would suggest that incremental improvements across the board
may be the best option in terms of reducing waste. Recent trends in US real estate have
affected what buyers are looking for in some positive ways, but there are still far too few
green homes available for buyers who want this option.!That makes it a frustrating search
for potential green home buyers, and discourages them from truly setting their sites on a
home that works for them. Additionally, because they aren’t making their voices heard,
many builders are not working to make homes that meet green specications (beyond the
bare minimum). They don’t realize the level of demand that would be there, if buyers felt
they would have the option.
 /
More Buyers Should Push for Green Homes
 /
There’s really one way to remedy the issue: buyers who want green homes should push
for them across as many channels as they can. If more buyers continue to ask for green
homes, more builders will produce these homes out of necessity. But buyers need to be
the catalysts in both demand and advocacy aimed toward other potential green buyers.
More of them want green homes, but they back down when they see these homes aren’t
available. Builders and sellers both need to know the value of creating these kinds of
homes or making changes to existing homes, so buyers will be more likely to purchase
those homes instead of other options. This might mean more negotiations with sellers and builders, and it will likely come at an increased cost — costs that will likely be recouped over time, but another upfront cost nonetheless.
 /
What are Buyers Looking For?
 /
When the average buyer!wants a green home, they don’t necessarily require one that’s
completely off grid. Some buyers will seek these out, but most will be looking for energy
efifciency, sustainable materials, and a smaller carbon footprint than what would be seen
with a standard house. In many cases, that’s enough to entice buyers to make a purchase,
and to keep them happy with the home they have selected. It also depends on the area of the country and the local market, because some buyers want and need different options due to weather or other factors.
 /
More Demand Will Require an Increase in Supply
 /
The more buyers start asking for green homes, the more likely it is that builders will create them. Sellers will also start making changes to the homes they are putting on the market, in order to entice buyers to come see their home instead of a different one. That’s an important consideration, too, since sellers may need to retrofit their homes in some ways and add options that they would not have chosen to put in if they were remaining in the house. Some green living changes can be expensive, but these changes don’t always have to be costly. There are lower priced options, as well.
 /
Trends are Moving in the Right Direction, at Least
 /
Even though there are still far too few green homes, and even though buyers aren’t making their voices heard as loudly as they could, the trend of green living is still going in the right direction. More buyers see the value of it, and more builders and sellers are starting to make changes in that direction. There is still a long way to go before energy efficiency and reducing waste becomes the standard for new homes and improved existing homes, but a larger pool of buyers demanding these features can help move the needle bit by bit.

A Comprehensive Approach To Energy Efficiency – Doing less with more

To Not talk about how disastrous Trump’s Presidency will be for the environment and the energy industry I decided to return to my roots in the residential market. Todays article is a bit old but its message is timeless. We have been concentrating on single devices like furnaces, refrigerators, windows seen as a whole instead of a holistic approach to a house.

https://www.greentechmedia.com/articles/read/the-real-problem-with-energy-efficiency

We’re Doing Residential Energy Efficiency All Wrong

Utilities are now spending nearly $7 billion a year on energy-efficiency programs. It seems we have little to show for it aside from expensive consultants who will model any results you would like.

These programs tend to focus their marketing on the energy savings or money savings from the projects. Consumers don’t care. If they did, we would see geometric growth instead of a resounding “meh.”

Others focus on better financing products, slicker sales pitches, faster energy audits, higher rebates or any of a myriad of other things.

In the residential sector, none of these are the problem. The lack of sales is the problem.

Projects are not being sold and implemented in substantial numbers. We need to slow it down, build relationships with consumers and educate them, learn and think systemically about the problems they have, and arrive at solutions that fit homeowner budgets.

I Finally Found The Water Walled House – In a very weird way

I saw this article on Digg.com a couple of weeks ago and tried to post it. When I went back to Digg to get the article and I could not find it, so I put up an older example. But then I put into Google “recent energy efficiency in the residential market” and there it was. So here it is.

‘Water-house’ Slashes Energy Needs

  //

 

As UN climate negotiators gather in Geneva this week, one Japan-inspired Hungarian inventor believes he has found a revolutionary and inexpensive way to construct buildings that could slash humanity’s energy needs.

And the magic ingredient for Matyas Gutai’s invention is simple: water. It was launched after a long process of testing and patenting and a decade of research and development at a Japanese university.

“Imagine a building without insulation, yet with a perfect indoor thermal balance, thanks to the properties of water,” the 34-year-old told AFP.

Saving Energy With Water Walls – I wanted to put up a brand new story

I saw a story on Digg about a designer (architect?) that got an award for building a house with water walls. But I could not find it again. This piece popped up and uses an older technology but you can get the idea from it.

Build a Water-Wall Home

Construct your very own water-wall home and learn about calculating water storage requirements, wall construction and solar basics.

By David Bainbridge
November/December 1983

The Morgan home in Davis, California has 14,000 pounds of thermal mass stored in its water walls, yet the containers blend in so well with the house design that they’re barely visible.

In many ways, passive solar homes are superior to those with active (mechanically assisted) heating and cooling systems. After all, passive solar systems don’t rely on auxiliary energy sources to perform (so they’ll work even when the power is off)… are generally simple and low in cost, combine energy collection and storage functions, have a long life, need little maintenance, and can often be built and installed by the home handy person, without special training or equipment.

But precisely because such “non-moving” systems have no pumps or controls to circulate warm or cool air, they typically rely on one key element: the thermal mass that stores and gives off absorbed heat or cold. A number of different items can be used to provide this energy-holding capacity, but just about the most effective and economical “To a water wall (a term that is a shorthand way of saying “contained water for thermal mass in passive solar homes”).

Even Georgia Has Tough Energy Codes Now – Some things have changed

Other things have not changed. I mean we are still burning coal to fuel electric generators, 30 years after we should have stopped. We still flirt with the idea of Nuclear Powered power plants. But here is part of the Georgia Code, a State not known for anything progressive.

http://www.southface.org/learning-center/library/res-code-faq#24

22.    What is the difference between a mass wall and a basement wall, and what are the insulation requirements for both?

A mass wall is a heavy wall that is more than half above grade wall and is constructed of a fairly massive material (e.g., concrete, block, insulated concrete forms, masonry cavity, non-veneered brick , adobe, compressed block, rammed earth, and solid logs). A basement wall is a wall that is more than half below grade and encloses conditioned space. Insulation requirements for basement walls and mass walls depend on the location of the insulation and the type of insulation (whether it is continuous or insulation installed in a cavity). Requirements also vary by climate zone. Below is a table detailing the insulation requirements in the energy code.

Wall Type Insulation Location and Type Climate Zone 4 Climate Zone 3 Climate Zone 2
Basement Wall Interior – Continuous R-10 R-5 R-0
Basement Wall Interior – Cavity R-13 R-13 R-13
Mass Wall Interior-Cavity R-13 R-13 R-13
Mass Wall Exterior or Integral- Continuous R-5 R-5 R-4
Mass Wall Interior – Continuous R-10 R-8 R-6

Las Vegas has made huge strides in conservation efforts

Yes I know there are many things that are wrong about Las Vegas. People shouldn’t even be there in the first place. The rape of the river that no longer reaches the sea. The rape of the pristine desert and the death of many Native Americans. I lived there for a year and there is also the cheesy nature of the culture. But when they do something right, you got to give them credit.

Nevada Energy Star Partners Demonstrate Peak Performance (Web Only)

September 01, 2012

Las Vegas may appear balmy and inviting with its sparkling pools and swaying palm trees, but those who live in Neon City know the truth: It’s too cold in the winter and too hot in the summer.

Unfortunately, hundreds of thousands of homes that were built during an amazing 50 years of rapid growth in the Southwest do not incorporate modern advances in energy performance to accommodate the wild swings of desert climate. As temperatures climb to 110°F in the summer, many homes leak large amounts of cooled air through gaps in ducts, roofs, windows, and doors. And when the frigid north wind drops the temperature below freezing in the winter, heated air escapes, leaving living rooms and bedrooms uncomfortably cold and drafty. While Las Vegans know their climate, they may not realize that they are paying to heat and cool the great outdoors.

The dramatic temperature shifts in the high-desert climate make Las Vegas an ideal place for homeowners who are looking to make their homes more comfortable and to save substantially on their energy bills. Funded in part by DOE’s Building America program, the Building America Retrofit Alliance is working with the Nevada ENERGY STAR Partners–Green Alliance (NESP–Green Alliance), and with Better Building Performance, a Las Vegas company, to upgrade two typical homes top to bottom. Their goal has been to show homeowners and remodelers how easy and effective energy performance upgrades can be.

Building The Buildings Of The Future – No Air conditioning is a place to start

This is an old piece but it is still as true today as it was then. Air conditioning and by that I mean cooling air when it is hot is very expensive both financially and with regards to energy consumption.

http://www.greentechmedia.com/articles/read/buildings-without-air-conditioners-the-latest-in-energy-efficiency-5413/

Buildings Without Air Conditioners: The Latest in Energy Efficiency

Air conditioners consume an inordinate amount of power in the U.S. and they aren’t very efficiently used. To save energy, some say leave them out.

Michael Kanellos: December 22, 2008

Sometimes the most efficient air conditioning system is not having one at all.

To curb energy consumption, architects with projects in temperate cities – Seattle, Portland, San Francisco – have started to design buildings without mechanical air conditioners. These buildings will have heaters in all likelihood, but not air conditioning (see Can Greentech Make Housing Cheaper and Green Buildings No Subsidies Needed).

“There are only five days a year you need cooling in Seattle,” said Amanda Sturgeon, an architect and senior associate at the firm Perkins + Will, who recently designed a building without a mechanical conditioner.

In some cases, architects are putting in air-side economizers, i.e., computer-controlled windows that open to let in cooling breezes (see The Solar Window). The General Services Administration building in San Francisco uses openable windows on 12 of its 18 floors that let in cool breezes at night that, ideally, keep the offices cool in the daytime.  There is no mechanical cooling in the open office areas.

This shift comes courtesy of two trends. One, building developers and contractors have latched onto green buildings as an economic opportunity. Designing a building to LEED Silver or Gold standards – the environmental building standards promulgated by the U.S. Green Building Council – only adds around 2 percent to the overall cost or less, according to various contractors, architects and researchers. Designing to the LEED Platinum standard can add only 6 percent if carefully planned. The trick, say Sturgeon and others, is to exploit as many passive, design-centric techniques for scoring LEED points before moving on to the potentially more expensive, equipment-centric ones like biomass boilers or new types of lighting systems.
