Green Building Elements

Taipei Pop Music Center has opened up an amazing architecture design competition for it’s new building. Nabito Architects has drafted and shared their vision of the new Taipei Pop Music Center composed of a “photovoltaic screen and a wall of LED panels”

The screen of the Pop Music Center may:

• have a LED media wall reporting news, weather, event info and ads.
• be powered entirely by the sun and set an example for green energy in the city of Taipei
• include photovoltaic cell technology, with an LED wall
• have controls set by a central computer, to show all events scheduled and more

“Our homes embrace the principles of eco-friendliness and cost-effectiveness, without sacrificing beauty. We can ensure that each dwelling achieves a gold or platinum LEED rating, depending on the particular finishes, building systems, and site design an owner chooses.” ~ Michelle Kaufmann Designs

Each Glidehouse home is solar ready with other renewable energy system options possible such as geothermal, wind generator or hybrid systems. Designed for clean, simple living. The Glidehouse is built in a factory, using the most modern and environmentally friendly building methods and materials.

Some eco features of the Glidehouse include:

• using healthy finishes such as non-toxic paints and formaldehyde-free cabinetry.
• it meets the Energy Star® program standards for energy efficient homes and meets the performance standards of the American Lung Association Health House program.
• it’s insulated with an air-barrier, open cell foam insulation, and all wood-to-wood framing joints are caulked, which makes the home airtight, energy efficient, and less likely to produce mold.
• it uses water-saving plumbing fixtures, on-demand water heaters, and a mechanical ventilation system that is 30% more efficient than typical forced-air systems.
• energy efficient, dual-pane glass windows and doors are placed throughout the home to maximize cross-ventilation and natural lighting, minimizing the need for artificial lighting and climate control.

With so many recent initiatives aimed at combating climate change, energy prices have obviously taken a hit. To compensate for this change, though, many architects and builders have begun using Daylighting to a great degree in construction.

“Daylighting,” or “daylight harvesting,” has been growing in popularity recently because it uses natural sunlight to its advantage. A number of automated systems are able to measure free natural sunlight and figure out how it should use controlled lighting in relation to that. Then, a system will automatically dim or brighten the lighting so that only artificial light which is needed is used. From an architect’s standpoint, it’s an important thing that the most beneficial entry points of daylight are decided on before construction. North-facing windows are great because they will definitely reduce unwanted glare. A designer, in turn, would decide on a quality lighting control system for dimming indoor light fixtures. There are a lot of systems out there, so deciding on a single one has a lot to do with finding a balance between natural lighting availability and extra electric lighting needs.

It’s a pleasure to finally begin writing here at Green Options! This time around, I’d like to focus on green building ambitions in the corporate world. I’ve been hearing a lot about Wal-Mart, Intel, etc. But have you heard about what Leviton just did with their headquarters? Read the rest of this entry »

AJC Architects have thought ahead to a hotter Utah in the sensible ideas incorporated into their  Wetland Discovery Point educational building that helps educate Utah schoolchildren about nature.

These are the green ideas in order of importance to sustainable design:

1. On-site solar panels for green electricity - to make net zero energy onsite;
2. Solar thermal collectors for hot water supply and radiant floor heating;
3. Radiant cooling via infloor cold water in the same circuits in summer; (great idea!)
   
4. 10-ft high trombe wall collects passive solar heat;
5. Butterfly roof for rainwater collection;
6. Rainwater collection used for toilets/landscaping;
7. Drought tolerant, native landscaping;
8. Maximimum openings for natural ventilation;
9. Low-water use fixtures and plumbing;

In addition there are the usual elements that garner so many LEED points:

1. 95% of the construction waste is recycled.
2. Use of FSC-certified woods and low VOC products.
3. High recycled content materials used throughout.

…and indeed, this building has gained LEED Platinum certification, the third to do so in Utah.

It’s a good example of the self-sufficient new design vernacular in sustainable design - including net zero solar power and the new butterfly roofs for rainwater harvesting for a water constrained future.

Because Utah, in the American Southwest, is an arid land and will be increasingly drought-prone as our hotter future heats up the region.

Did you know that if you install a Biomass Stove – wood, pellets, etc. that you can nab a  30% tax credit ($1,500  max) up until 2010? Who knows that homeowners can get a 30% tax break for installing Solar Hot Water Heating until  2016? Maybe the new American Recovery and Reinvestment Act (ARRA) which was signed into law by President Obama in February 2009 isn’t as complicated as the IRS tax code but does anyone really want to delve into the 400 pages of legislation to figure all the ins and outs about how to qualify for the green tax credits available to homeowners?

In a Cliff’s Notes version of the myriad incentives, rebates, and tax incentives GREENandSAVE has created a Federal Tax Incentive Decoder and condensed the material to 11 bite sized pages. Best of all, this resource does not cost a dime and can be downloaded at: http://www.greenandsave.com/homecheckup/free_federal_tax_incentive_decoder

Given the climate change coming to most regions of the US, this new roof idea is a great passive cooling solution worth looking at even if you don’t live in the desert regions… now.

Because, by century’s end; you might.

“Summer temperatures in Florida could rise by 10.5F, with the heat effect multiplied by decreased rainfall under the higher emissions scenario. There would be increased hurricane intensity and rising sea levels leads to loss of wetlands and coastal areas.”

“When you’re out in the desert, shade is gold. It’s the most valuable asset you have, so to make more shade was [the] strategy,” says Lloyd Russell of this house he designed to withstand both the scorching heat and the cold of the desert for a client in Southern California.

Russell’s very low carbon way to cool a home is another example of how creatively some architects are thinking out of the box and in the process creating an entirely new design vernacular - architecture for zero energy use in a carbon-constrained, hotter, wilder new world.

If every building had a white roof, we would be able to cool the surrounding areas. That is the reasoning behind a California law about to go into effect next month requiring light reflective roofs on all new buildings. It is already the law for new flat roofs here.

Here, architect Richard Meier and his partner Michael Palladino have apparently created a design to go one further. It’s entirely white; roofs, walls, and interiors.

So this luxury design of a cool  and airy Southern California beach house is glamorous and climate friendly.

Well, no. The McMansion-sized size of the thing at  4,280-sq.-ft is not so planet friendly; because it takes more energy to heat and cool a larger space. But this house would be well suited for a ground heat exchange to passively heat and cool itself with 55 degree air cooled from 10  feet under the ground.

As architects in California get closer to 2020, they will need to think more about passive cooling and heating and zero energy houses, as that will be the law by 2020. All new building must be zero energy by then.

Incorporate solar roofing on the white roof, and this could be a zero energy house.

The blue of a solar roof would visually extend right out to the ocean. (And conceal that horrible mess of  mechanical contraptions on that roof.) White elastomeric cool roof paint under the solar panels would help cool the modules making them more efficient on hot days.

But are architects thinking about these things?

With 2020 almost upon us:  “The beams at the roof, located above the horizontal framing, express the structural rhythm and layering of components,” explains the architect. “This cadence is repeated with the joinery of the painted aluminum exterior wall panels and modular windows. The mass of the exterior plaster walls are juxtaposed to the transparent glazed facades, creating a mosaic of layered materials.”

Blah, blah, blah.

It wasn’t exactly a quite hush that settled over the San Francisco’s Moscone Center for the 50th PCBC convention but the crowds and exhibitors for this annual builders convention came in about one-half of last year. Nonetheless, in this era of minimalism and slimming down the show offered an array of notable speakers and some innovative products. Now of course, with the slogan “The New Age of Innovation” we hoped for more progressive Green products and not just in a marketing sense.

On the creatively intriguing side, we walked into the Icynene Inc. display booth only knowing that they create their Icynene LD-R-50 spray foam insulation partially from Castor oil. Honestly, we didn’t exactly know the origin of Castor oil. Castor oil comes from Castor beans (not true beans from Castor plant) and don’t serve a normal food source, so not food for insulation here. Castor crops don’t require pesticides or fungicides or even water to grow and are rapidly renewable. For this insulation, they use 15 percent castor oil (and unfortunately 85 percent polyglycol, which in our eyes is like using B15 biodiesel. Fifteen percent is better than zero percent but still a long way to go. This product helps eliminate dust, pollen and contains no VOCs as it is water blown. Most traditional cellulose insulation comes from 80% newspaper (up to100% post-consumer recycled) and 20% binders and fire-retardants, commonly borax, boric acid, sulfuric acid, ammonium sulfates and/or other chemical compounds. Smell the goodness.
