    Affordable Solar Powered Air Conditioning In A Neat Little Package Is Finally Here

    ive percent of America’s electricity is used for residential air conditioning, and it is considered now to be a necessity, not a luxury. It’s usually needed most when the sun is shining, so as I have noted since 2006, Solar Powered Air Conditioning Just Makes Sense. For most of that time I have been looking at absorption units that run like a propane fridge, but I recently mused that perhaps it is time for a change in the way we think about this:

    I am wondering if the solar powered air conditioner might not be in the end a small, high efficiency home with a small, high efficiency air conditioner powered by a big honking bank of photovoltaics, and be done with it.

    Why Construction Is Expensive

    Being a highly cost-effective design-build firm, we spend a significant amount of time and effort on project budgets. We publish the construction costs of most of our projects, discuss pricing in many of our posts, and have even gone to the extent of designing a construction cost cheat sheet. To us, the design and the finances of a project are interconnected. We’ve never cared for the vague and uninformed approach toward construction costs that are all too common in the architecture industry. In fact, it’s common for us to dive into a realistic construction budget discussion as early on as the initial interview for a new project.

    7 reasons why green buildings are good for business

    The level of interest in and desire for ‘greener’ buildings is now pretty much mainstream. Consumers and businesses are taking seriously the benefits of operating in an environmentally responsible manner. As consequence it is becoming an expectation that companies will incorporate environmentally aware approaches in everything that they do, including their buildings.

    So, why do it? Why does it matter and what is the business benefit?

    DIY Black Tea Window Cleaner

    o-it-yourself cleaning and cosmetics have kind of become my obsession my hobby. I think about how I used to slap down my cold hard cash for all those creepy chemicals, those toxins just sitting under my sink, with their smells that seemed to permeate my every pore. I remember the artificial aqua, the glowing neon green, such unnaturally bright colors. And I’ll never forget that cloying, eye-watering suffocation that came from cleaning a too-tiny bathroomwith too many kinds of soaps and powders and pastes and bleaches. Oof.

    I think back to those days and I can’t help but smile. Because now, I’m spending mere pennies and my cleansers and cosmetics are good enough to eat – literally! And my house is just as clean as ever and my body is just as beautiful, and gosh, but everything is so much more pleasant.

    New Mexican Adobe, German Efficiency Style

    I’ve seen several projects pursue both LEED Platinum and Passive House certification, but I can’t think of any that actually went through with the aim other than this Passive House, Platinum-certified home in Taos, New Mexico. The 2,400 square-foot home has three bedrooms, two bathrooms, a garage, and 1.1 acres of land with a serene, scenic view of Taos Mountain to the east, Truchas Peaks to the South, and pasture land to the west.

    The Pros and Cons of Switching to a Tankless Water Heater

    If the idea of constantly heating your water in a big tank sitting in your basement sounds mighty inefficient and wasteful to you, then a tankless water heater may be the right option for you. I’ve researched some of the advantages of a tankless water heater system, alongside some of the compromises that come with the compact, more energy efficient option.

    PROS

    There are many advantages to going with a tankless water heater. From increased energy efficiency and lowered operating costs to space savings and extended lifespan, find out more about what makes for good reasons to go tankless.

    Energy Savings / Operating Costs
    The first thought on tankless water heaters is generally: how much energy/money am I going to save? Well right off the bat, you’re going to be spending MORE money to get a tankless water heater and all its plumbing in place. While a tankless water heater costs more upfront, your operating costs down the line should start to make up for it. What you’re saving is in not having to spend money on standby heat, meaning you’re not wasting money heating water in a tank that’s just sitting idly waiting for someone to need hot water. Tankless systems provide that hot water on demand, instantaneously, when you need it, so you don’t have to waste energy heating unused water. You’re also not losing heat that’s idly sitting in a tank that, while insulated, is still going to lose heat and require constant reheating. Our friendly federal government has a nice energy cost calculator.

    Efficient Living: Faucet Aerators

    Easy to install, these faucet aerators not only swivel, spray and stream, but they also feature a flip switch that lets you briefly turn the water on and off. This is great while washing dishes because it maintains the water at your perfect temperature, while allowing you to temporarily shut off the water when you’re doing things like: (1) transferring big pots after rinsing, or (2) each time you lean over to fill a dish rack. Because you’re not changing the entire faucet, just adding to the tip, they’re great for

    25 Places to Donate Your Stuff

    I think we can all agree that we probably have too much of something or items that serve no real purpose in our homes, whether it’s clothes, DVDs we never watch, unused kitchen gear, the list goes on. National charity organizations like Goodwill and the Salvation Army are always great places to donate, but while looking for more specific ways to donate some children’s toys I came across multiple websites for children’s hospitals that are collecting gently used books and toys for their waiting rooms and activity centers.

    This got me thinking that there are likely lots of ways to donate items to fill a direct need. I find it incredibly motivating to think of de-cluttering in this way; if someone else can put my stuff to better use, that’s exciting.

    Will Micro Apartments Go Macro?

    Construction has begun on an infill project at 38 Harriet Street in San Francisco that its developer, builder, and module supplier believe could determine whether micro apartments remain a highly publicized curiosity or are seen as legitimate housing alternatives for young urban professionals seeking cheaper, greener, and walkable living spaces.

    “There are a lot of eyes on this project, a lot of interest,” says Naomi Porat, president and co-founder of Zeta Communities, whose factory in Sacramento, Calif., is close to completing the 12- by 65-foot modules that will be used to construct an 11,775-square-foot four-story wood-framed building squeezed onto a 3,750-square-foot lot in this city’s South of Market Street (SoMa) district. That building will contain 23 micro apartments measuring around 300 square feet each, with nine-foot ceilings, kitchens and baths, washers and dryers, and multipurpose built-ins for storage and workspaces that can convert to sleeping areas.

    Atlanta considers new storm water rules as part of rainwater harvesting program

    A renewed push is underway in Atlanta to harvest rainwater and improve the management of storm water in an era of sustained drought.

    Rainwater harvesting is one proposed response to the need for better management of water resources. Credit: Southeast Rainwater Harvesting Systems Association

    Advocates say a regional rainwater harvesting program could produce more than 20 million gallons of water a day. That represents about 16 percent of metro Atlanta’s net consumptive use of about 125 million gallons a day, according to the latest figures maintained by the Atlanta Regional Commission.

    Two efforts are ramping up to improve the management of the region’s water resources: The drafting of potential new storm water regulations in Atlanta that would apply to all new homes, and to certain additions to existing homes and commercial properties; And, a renewed push throughout the region to encourage property owners to harvest rainwater.

    dan price: my tiny house

    with a refreshing contrast to the seemingly budget-less, material extensive projects published around the internet, dan price’s
    ‘tiny house’ offers a more sobering sustainability in construction and consciousness. the concept revisits the basic principles of a site,
    finding that perfect natural balance between sun, shading, ventilation, and a water source. ‘primitive living’ is above all a process of
    discovery that requires time to intimately understand the terrain, the materials and more importantly your own personal needs.
    the project challenges the very question of human necessity with regards to our culture of ‘living.’

    the dwelling is embedded into the ground, with a larger perimeter than the actual oval form of the main living space to leave room for
    future expansion and for ease of building. thick plastic covers the floor as a water barrier and wraps over the vertically placed 2×6
    wood planks. paving stones line the inside of the partition to secure the footprint from shifting while thin strips are screwed laterally to
    the upper sections to reinforce the circular shape. 2×4 wood members are stacked along their short axes to create a type of large laminated
    beam as the roof, capable of supporting the soil that will eventually insulate the entire construct. holes are cut out of the shell to make
    a door and angled skylight, inviting light and views, with flashing elements to seal the connections and keep wood and water separate.
    from this point, each person possesses the ability to customize their new home to their individual desires as this is, after all, the basic unit of what every other project stems from.

    Zero Net-Energy Ready Homes to be Certified by Energy Department Partnership

    For people who think Passive House is a Fad.

    On Monday, August 20, the U.S. Department of Energy (DOE) announced a newpartnership between the DOE Challenge Homeprogram and the Passive House Institute US to cooperate on the promotion of various levels of high-performance buildings on the path to zero net-energy.

    This news is a huge development for the passive house community and for PHIUS. The endorsement of PHIUS+ passive house certification through the DOE instantly makes passive house the most energy efficient option for builders, designers and developers who want to achieve a zero energy building. This recognition will go a long way toward making passive house mainstream.

    This took a lot of time and effort, and we owe thanks to Sam Rashkin, Chief Architect at the DOE, whose knowledge, vision and determination were critical to the effort. (Sam was the keynote at last year’s North American Passive House Conference.)

    So, how does this partnership change current PHIUS+ passive house certification and what do consultants need to know?

    In a nutshell: not much. A passive house already fulfills most of the Challenge Home requirements – certification essentially remains the same process with a few minor additions! Those additions are very good improvements, making the home even better. Indoor air quality requirements ask for low VOC materials and the water efficiency requirements establish a reasonable savings baseline, all good things.

    The Challenge Home requires rigorous third-party, on-site verification, which already is part of PHIUS+. PHIUS+ certified RESNET Raters already use an advanced passive house checklist created specifically for passive houses. (This testing protocol is actually more rigorous than the one the Challenge Home is using.)

    What Challenge Home brings to the table that PHIUS+ did not before is a more formalized exterior water management and flashing checklist. Having seen quite a few bad water management details during certification so far, we are happy to add a more formalized process to assure the long term durability of the house. QAQC is crucial to assure quality in execution, actual performance and peace of mind for the client we found.

    Passive Solar Design Basics

    Passive solar design begins with the simple idea that you can build a house that uses natural heating, cooling, ventilation and daylighting. These homes require much less fossil fuel energy to heat and cool than conventional homes do, which is better for the environment and saves passive solar homeowners money. Passive solar homes are comfortable to live in because they are designed to radiate heat in winter, maintain a comfortable year-round temperature, ventilate naturally, and let in plenty of natural light.

    I became interested in sustainable design, specifically passive solar design, as a young architect

    Yes, U.S. Oil and Gas Production Is Increasing, but Energy Efficiency Is Still the Number One Resource

    A variety of recent articles have trumpeted how U.S. oil and gas production is up. For example, Daniel Yergin, in a New York Timesop ed, notes that U.S. oil production has increased 1.6 million barrels per day since 1998 and that a further 0.6 million barrel increase may be possible this year. He also notes how shale gas is now 37% of U.S. production, up from 2% a dozen years ago. And he quotes President Obama as saying that shale gas development had by 2010 supported 600,000 jobs (this includes direct, indirect and induced jobs). EIA notes that U.S. oil production in the first quarter of 2012 is at the highest level since 1998. These increases are largely driven by advances in hydraulic

    Top 5 Permeable Driveways

    Driveways and other parking areas are typically paved with asphalt or concrete, and are not only unattractive, but detrimental to the environment. When it rains, debris and pollutants flow off these impervious surfaces into our waterways, many times via the sewer system, which contributes to stormwater runoff pollution. See the top 5 examples here……..

    Ventilation in Passive Housing – Why Doesn’t Airtight Housing Choke?

    We know that ventilation is incredibly important in developing comfortable and practical interior design – but when we’re dealing with a passive house; a highly energy efficient building that is known for its key feature of airtight insulation – the means of ventilation are paramount.
    The passive house design means that through high levels of insulation and window energy efficiency, airflow into of out of the building is limited. A complete lack of fresh air amounts to an unliveable building.
    Equally important as this highly energy efficient design – which generally gets all the media attention – are the ventilation processes that, as anyone who deals in passive design development knows, are the key element in providing liveable interiors.
    However, air quality issues are not the only problem that faces a building that doesn’t ‘breathe’. Moisture can develop, causing mold and.

    Energy efficient home nets cash for owners

    If things go as planned, Ashley Warren and Anthony Spicer won’t pay an electric bill at their new home in Whitley County. They’ll be getting a check from the power company instead.

    The couple and their three daughters recently moved into a house designed to use 90 percent less energy for heating and cooling than a conventional home.

    The house also has solar panels on the roof that generate power to sell back to the electric company.

    Spicer said the electric bill at the house they rented before moving averaged $350 to $370 a month.

    “It’s going to mean everything” to get rid of that payment, Spicer said. “We’re going to be able to buy things we couldn’t normally buy because of this.”

    Light 12-Glazed Window on the Horizon, at R-38

    In the USA, most windows are probably single- or double-glazed and some builders will use triple-glazed windows for Passive House and other high-performance homes. But in Hanover, Germany, a 12-glazed window prototype by Mariusz Paszkowski and Antoni Kostka was the star of the recent International Passive House Conference, according toDer Standard. Check out these windows with aerogel!

    The two scientists, in conjunction with SUPERWINDOWS, showcased INVIS160stack and INVIS160tweed, and both of the prototypes are about 160 mm thick, though they weigh no more than a double- or triple-glazed window unit.
