Top 5 Green Building Trends for 2011

Thursday, January 27th, 2011

Amicus Green Building Center’s Jason Holstine Shares his take with us on what is hot in green building for 2011.

When you think of green building and home energy efficiency in the DC Metro Area, Amicus Green Building Center should come to mind! The one stop shop for green building, healthy living and energy efficiency products and services for the DC Metro area is alive and well in Kensington, Maryland. Founder and President of Amicus Green Building Center, Jason Holstine shares his predictions for the hot green building items for the new year. The count down is on, take some tips from Jason as he walks us through his green building trending for 2011.

As we turn the corner into 2011, here are five trends we’re seeing in our corner of the green building world:

(5) Cork. It’s not just for wine bottles anymore. Cork floors have been around for more than 100 years, but they’re really catching on now. Why? Cork cells absorb energy—your joints will like that—and are warmer than other hard-surface floors. They are naturally antibacterial and fire resistant. They are long lasting and durable. Cork comes from the bark of an oak tree every 9 years—trees can be 200 years old and still producing—so they’re extremely environmentally sustainable.  Be careful on the brand you pick—some contain formaldehyde in the binders or solvent-based stains—but, of course, none of our brands do.

(4) When is a no VOC paint not a healthy paint? When it still has “exempted VOCs” (the EPA doesn’t regulate volatile organic chemicals (VOCs) for indoor air quality, it regulates them because they react with sunlight to create ozone (smog); those that don’t react with sunlight aren’t regulated but may still create acute health problems), acetone, crystalline silica, ethylene glycol, and VOC-based colorants. Many paints labeled as “no VOC” or “low VOC” still have a bunch of chemicals like these that can be neurotoxic, cause headaches and breathing problems. Let alone the fact that they may be miserable performers once on the wall. Look for a paint that is truly zero VOC, nontoxic and a great performer—the Smithsonian does.

(3) LED’s. CFLs (those twisty lightbulbs) are so 2003. Light emitting diodes (LEDs) are the way of the future—they use even less electricity than CFLs, can last decades, and they don’t have mercury. But, as with all new technologies, buyer beware. Some brands are certainly much better than others. Energy Star’s LED label comes out in August 2011. In the meantime, we’ve vetted and tracked customer experience on what to use where and the trusted brands.

(2) Cabinets.  We’re seeing a big upswing in kitchen and bath remodeling projects. The recession notwithstanding, these are always popular projects. And cabinets are always big line items in a K&B project—and why not, since they take a lot of space, get major use and beating, and are a major source of offgassing chemicals and lots of wood. So they also present a great greening opportunity. We have very cool custom and production design options.  Our EcoFriendly line of product cabinets offer several key hooks, all in one product: ZERO VOCs or formaldehyde; FSC-certified woods; made nearby in South Carolina (American jobs and less carbon footprint); and they’re really well made so they’ll last a very long time. Those are a lot of checkmarks on one product category. And our custom woodworkers make very slick styles out of bamboo, sorghum stalk, reclaimed walnut, recycled plastic panels, and other fantastic materials.

(1) The Package: People often get tripped up on what a green project should be—is it about health? Saving energy? Durability to last a long time? Making Al Gore happy? They think it’s too hard and will have to leave some of these worthy goals behind. The hard truth is a great green project is ALL OF THE ABOVE. The easy truth is that a well-done project is a package of ALL these great features and goals, the right design, products, and craftsmanship. A body of best practices has emerged to make this package easier to attain. Suppliers, designers, and contractors with the right experience, mindset and good project management can make all the difference in the world. So make sure you work with folks with strong experience and understanding of green elements and what can make or break a super project. Don’t compromise when you don’t have to—you and your home will be happier for it for a long time.

Moving Toward Net Zero- Part I of a Series

Adventures of a Home Energy Nerd- an Arlington Based Contribution.

Preamble: I am a total energy conservation nerd on top of being a geek about pretty much anything having to do with the environment. I have not given myself this title of “energy nerd”, but rather it has been lovingly bestowed upon me by my two children who are nearing and beginning their teen years (go figure), and by my husband. I am sure my two dogs would call me that as well if they could talk, but they do give me the same type of glazed over looks when I start talking about energy stuff, so I know they are thinking it. With that being said, I am lucky enough to have a family who has allowed me to use our humble home as an awesome laboratory in which to create endless amounts of chaos and mess, and to spend endless amounts of time and money in order to learn more about sustainable building, and of course for the ultimate quest- to save energy!

I started getting really interested in green building and home energy savings when I was planning an addition to our very modest Arlington home about seven years ago. At that point in time, green building techniques were in their infancy in the D.C. area in terms of local product availability, the knowledge pool, etc… Needless to say, this made building an energy-efficient addition with some other green features quite a challenge. But, we slogged through it, managing to take a fairly leaky and uninsulated 1940’s cape code to a point where it was just on the border of being overly tight, then adding a mechanical ventilation system, replacing other systems, and ultimately adding modest sized solar electric and hot water systems. Through this addition and a number of other home renovations and improvements, I have learned a great deal and hope to share with you over the coming months some of this knowledge, our successes and failures, lessons learned, and some rather humorous stories along the way. I hope you enjoy them!

Nauck Community gets a Green Voice

Wednesday, January 12th, 2011

Bonstra Haresign’s New Construction, The Macedonian Building on Shirlington Road, brings a deeper sense of Community and a new shade of green to Nauck in Arlington.

Situated in the thick of things, the new construction just in front of the Macedonia Baptist Church on Shirlington Road will bring a deeper sense of connectedness and community to the Village of Nauck. Architect Matthew Corell of Bonstra Haresign answered a strong call for a building that could enable low income families to live in homes that are “environmentally and community responsible”.

Part of Bonstra Haresign’s mantra is that they are “rooted in community values and collaboration [Bonstra Haresign is] a full service architecture firm committed to design excellence and client service.” They saw this community in need, and set out to achieve a building that is not only EarthCraft Certified, but also a community incubator program. Corell mentions that this 35 unit building of one and two bedroom homes isn’t just a pretty new face on the Nauck Village Center map, “The Macedonian and it’s big sister The Shelton (across the street) are the first two buildings to be developed according to the Nauck Village Action Plan and act as a gateway from the low-residential single family homes to the north and the soon-to-be density to the south and on down to the more developed Shirlington area.”  Corell and his team utilized the difficulties of the Nauck Village Action Plan (the planning and zoning for the community) to their advantage- creating a sleek, yet modest profile with some rather interesting, thoughtful touches. Note that this building is going through the rigorous EarthCraft Virginia testing to verify that the property is being built to health living standards.

From bottom to top, The Macedonian is something special for the Nauck Community. This 5 story building looks like a four story building from some angles, this is part of the zoning that provided Corell the opportunity to create something a little bit different with this building. In the first level of the building, you will find offices and “incubator” rooms for community members who are seeking to begin their own small businesses; this incubator area gives them a head start with office space to commence working on excelling. The one and two bedroom floorplans are available to families who meet specific income requirements to that they can live in a building which has been constructed to high energy efficiency and green building standards. The slight step in the building where it becomes a 4-5 story building, is an open air roof-top green space: an intricate system of sedum and other succulents called a living roof. Corell recalls this living roof would “add a center piece for the tenants and a private outdoor space that they could enjoy year round. The green roof, by LiveRoof, also has huge environmental impacts: diverting water from the local sewer system, reducing the heat gain of the building and providing an additional layer of insulation…  The upper roof is also energy efficient and is called a “cool roof” due to its high albedo rating.  It has minimal mechanical condensers and fans. ” The living roof is just one way that his team brought a beautiful and effective way to bring energy efficiency and performance to the project.

The standards that the Bozuto Construction company took in creating the Bonstra Haresign design has been that of advanced framing techniques, high performance energy efficient  insulation strategy and healthy indoor air systems through proper air sealing techniques and the utilization of a fresh air intake system for the whole property. The HVAC system is a topic that the whole design and construction team struggled with; Corell wanted a product that would allow for the fresh air intake system but would not be the typical “farm” of HVAC units on the rooftop. One of their engineers suggested the Mitsubishi unit, that they ultimately opted for after much discussion with the HVAC subcontractors who were not familiar with this type of ducted fresh air intake system. The Mitsubishi unit that they purchased is a product that is often utilized in commercial buildings, but is quite widely used in Japanese construction of all sorts. One of the many bonuses of this system is that it will “provided ducted fresh air to each unit.” On the energy efficiency front, this system “will send it’s cooling refrigerant to the condensers in the garage which will then convert this and send it to the west side. So instead of converting 100 degree air to 70, the Mitsubishi takes the 74 degree refrigerant and converts it to 70;” thereby reducing the conditioning needs since air will be constantly tempered. Something that, again, sets this building apart is the light colored roof designed to reflect light and keep the building cooler in the summer and warmer in the winter, as Corell referenced before regarding the “high albedo”.

Not only is The Macedonian project an energy-efficient, low income, multi-family project in Arlington, but it is also a community development project. It’s prime location with close proximity to 395 access, a number of ART buses and even the main S. Glebe thoroughfare, The Macedonian is a great place to kick this historic community back into high gear for its inhabitants. The incorporation of a project such as this within walking distance to the historic Drew Model School, walking distance to the Nauck Town Center and even a gentle stroll to the Village of Shirlington shops, and restaurants-  is bringing new life and new opportunity to this section of the Nauck Community.
