Extreme Green Homes: Taking the Living Home to the Next Level

Thursday, December 27th, 2012

Extreme green houses. Not  all of these are for our climate; these houses take green building to extremes.

Some architects, such as Sean Griffiths, say things  I think living walls have become a substitute for having any ideas when they are talking about the recent widespread use of plants in architecture. Not landscape architecture, mind you, but full –tilt I’m gonna build me a house- architecture.  This could have to do with his very obvious and well thought out reasoning such as a lack of consideration for how the plants will get their light, the weight on walls, to even how they will re-seed themselves! Mr. Griffiths makes a good point, but there is a flip-side to this amazing use of nature in architecture.

On the other side of the spectrum reigns architects from the extreme school of thought such as Vo Trong Nghia based out of Ho Chi Mign City, Vietnam who happened to win the 2012 House Category at the World Architecture Festival for this concept of natural ventilation, air purification and heat reduction based on the use of vertical walls of plants. These walls were not only beautiful and elegant, but introduced an element of purification and a reduced reliance on power and resources in a city known for its frequent power outages and shortage of energy.  Vo Trong Nghnia’s plan was simple. He would put walls of plants on shelving like planters across the north and south facing walls at varying levels depending on the growth structure of the specific plants with a thin amount of window glazing (sort of acting as a terrarium) and a well that drafts and pulls the naturally purified air through the core of this home, which is capped off with a green, or living roof. The living roof also acts as a natural sound insulator and protector for the elements as well.  This home is a perfect example of a extreme architecture that takes sustainability to a new level perfect for a humid, tropical climate!

In Toronto, a meadow home takes living in a living home into another direction entirely. This home doesn’t have the living walls, but an entire living roof that insulates and protects the home almost as if the home was built like a 1930’s central-plains dug-out. The design is like atomic-ranch met the Jetson’s and had a party with the Brady Bunch, but then some hipsters came along and chilled everything out. The home not only has been built into a hill and sort of melds into the landscape, but also has ground-sourced, or geo-thermal heating and cooling, which make this home even more efficient. Architect, Ian MacDonald set up the periscope windows with the perfect concept of cross-ventilation in mind.  This home in Canada is thousands of miles and climate zones away from Ho Chi Minh city, but the idea is still the same, utilize the plants to make a home more insulated from the elements. Photos of this home are via architecture-view.

Next time, we’ll talk about what we can do in our area to utilize plants in our homes, since Vo Trong Nghnia’s concept is a bit too humid-climate zone for us, and Ian MacDonald’s design plan is pushing for a meadowland. What kind of extreme green homes can be built in a mixed humid climate?

Take a Trip into a Pocket- Neighborhood, that is…

Resident Green Real Estate Expert, Genevieve Concannon sheds light on a growing trend in neighborhood development.

We love it when Genevieve gives us the goods on Northern Virginia Real Estate. We love it even more when she covers our projects and developments that we’ve worked hard to help master in the area. What we love the most is when she finds out about growing trends that affect the way that developers see sustainability and green building techniques and ideas. She met with Architect Sam Young to hear more about his thoughts behind the pocket neighborhood concept and what it means to the area where we all live, work and play.

Neighborhoods are where we live and grow. What do you want in yours?

A few months ago, I put out this article for an online publication, but I thought you guys might be interested to see some of what I do when I’m not just helping people buy and sell real estate. I hope you enjoy it and anything that you take away, I hope we can use that to find your next place.

With many people shifting away from the more-more-more mentality to the less-is-more mentality, the concept of pocket neighborhoods supports community building, sustainability and vibrancy.

“Making Due with less can be better for us…” Architect Sam Young says as he tips his mug back for the last of his coffee. I think he wants more, but he may be caffeinated enough for the both of us; “…. you see, with these pocket neighborhoods, you can focus on the interpersonal relationships, grow your community and have sustainability all in one.” Young is not just an architect; he is an environmentally conscious architect who puts very  much emphasis on passive design and planning up front that will allow his clients to enjoy the benefits of a lifestyle that suits their needs. He gets it. We’ve been talking all morning about the idea that as the population of the digital age gets larger and larger and the boomers are starting to realize that they want to downsize, the concept of pocket neighbor hoods with these smaller backyards and larger community gathering areas are growing in popularity. He is toying with the idea of designing homes in neighborhoods that are in line with a more “come on up to my front porch” feel where the backyard is much smaller than the traditional American yard, the front yard is larger and connected to a green space and you can see what is going on around the community.

Come on up to My Front Porch

Fundamentally, architecture and design can solve everything; at least, this is Young’s philosophy. Quality of life can improve, services come later, but if you design a home where people are invited up and feel that they can commune with one another the strength of the community is realized. Young states that “instead of the idea of “land-house-land-house… of the classic suburban model, with the pocket neighborhood concept, you get a community neighborhood model where homes are oriented in a way that the homeowners feel a sense of privacy and community.”  I recently even read an article where a gentleman said he remodeled the front elevation of his 1940′s home, which was formerly a small portico into an additional one thousand or more square feet of usable living space. Every Thursday evening, starting at about happy hour time, the neighbors stroll on over -pot-luck style- and unwind about the day’s events and what is going on in the ‘hood. It gives him a sense of pride in his beautiful home and the block a deep sense of community. If the lights are on, come on up to my front porch; a warm, inviting, space where people are like family. Main Street America in a place that often feels quite transient and disconnected.

Putting a Value on Community Energy

Architects, like Young, often put eves and overhangs into their good designs not even thinking that they are a part of green building program points. LEED gives points for usable outdoor living space as does the City of Austin’s Green Building Program, Arlington Green Home Choice Program and even EarthCraft Virginia. There is a value in the usable outdoor space beyond the community building, and beyond the aesthetics. The value is in the vibrancy that the home will achieve from gaining an additional usable outdoor room; hooray for vitamin D the good ole natural way and hooray for a place to hang your begonias.

Trending with the Pacific NW

It is interesting to think that this concept is currently trending with the boomers largely in the Pacific Northwest.Why would the concept of downsizing to smaller homes with smaller yards with larger front yards and more communal areas be making an upswing in modern American urban developments? Young opines that “smaller footprints means less energy consumption, less maintenance and again, that general sense of making due with less as being better.”  As a function of sustainability, a smaller footprint makes sense and the dense urban planning of a pocket neighborhood also makes sense. One thing is for certain, a more communal living space may not be for everyone (some people don’t share well with others), but for those who like the idea of coming on up to their neighbors’ porches for a cold glass of iced tea on a summer afternoon, or for s’mores when it starts to chill… pocket neighborhoods could be all the rage. – Genevieve Concannon

No Longer a Trend, Green Building is a Tried and True Way to Build for a Sustainable Future

Even 10 years ago, people used to shrug their shoulders and cock their head to one side when you told them that you were into green building consulting and energy efficiency. I wouldn’t say that things have gone mainstream, but yeah, things have gone main stream. With more builders, developers and architects getting the education about how to build in a more sustainable and energy efficient manner, the dollars and cents of it all are starting to add up into just making cents into sense. Many architects add sustainability features into their design plans without even knowing that they are “going green” because of a long standing sense of beauty that comes from the final product, such as eves and overhangs that shade from sun, or useable front porches. How about using 16 on center for structural integrity for a more energy efficient framing program and more cost effective use of lumber? Everyone likes when costs go down on a build, right?So, what is green building really, aside from the idea that the home will be more kind to the environment, so to speak?

Green Building Defined

Green building is the practice of understanding the construction science that incorporates the air quality, water quality and ultimately the energy consumption of the building and of course, the products selected to actually construct the building. When you take all of these elements and design a plan that incorporates the acknowledgement of each part, you can work to create a building that functions as a system. How many times have you heard me talk about the house as a system? It is true! The awesome thing is that there are so many different levels of sustainable building from someone just doing the bare minimum just to improve their indoor air quality, to a home that is entirely net-zero (a home that has zero-energy emissions or off-put annually)! If you want to talk more about the true meaning of green building and energy efficiency, let’s start a conversation!

Award Winning Architect Stresses Certification Process

Thursday, April 14th, 2011

EnviroHomeDesign’s Marta Layseca knows her green building and shares her story case study about the third party certification process.

At the Arlington County Green It Lecture Series mediated by the Green Home Choice Program manager, Helen Reinke-Wilt, Marta Layseca was able to discuss two of her recent retrofit stories in the Arlington area and stress to the audience how the third party verification service is an absolutely imperative part of the green building process. What is the 3rd party verification part of the construction process anyways? Well, it is the part of the process where the project manager or builder has selected an outside authority to come into the project and certify that the project has been held to specific standards.

In the case of Mrs. Layseca’s projects in Virginia, the Green Home Choice Program is the County green building program and the EarthCraft Virginia Green Building program is the regional green building program which provides third party verification that the home is being built to specific standards.

The EarthCraft program institutes a standard checklist that the builder follows from the outset of the build. From the construction charrette to the final finish out, the builder will follow the checklist with the guidance of an accredited technical adviser who will inspect and consult on the building practices and techniques throughout the building process to ensure that the home is “built tight and ultimately ventilated right” as they say at EarthCraft.

Third party verification services not only provide quality control and performance testing, but they also can allow for the construction team to have a mediation with the third party who can come on site to discuss how “things should be done” if a technique or application is not being done properly.

Take for instance, if the duct work is not being sealed with mastic, and the HVAC contractor is arguing that they only want to use tape; the third party verification service provider such as an EarthCraft adviser can intervene and discuss why the technique being used is not the best, and correct the situation to help the builder achieve a higher performance, more energy efficient design. This will ultimately arrive at a healthier, more cost saving product for the builder and a more satisfied client. Now who can argue with that?!

Arlington Based Architect Greens It at Lecture Series

Tuesday, April 5th, 2011

The Green It Series with the Arlington Green Home Choice Program featured speaker Marta Layseca of EnviroHomeDesign at last night’s lecture series at the Arlington Central Library.

Arlington County has a very strong green building community and they keep it so by hosting community based lecture series such as the one hosted at the Central library last night featuring award winning architect Marta Layseca of EnviroHomeDesign. The series topic focused on the retrofitting of existing homes which are being remodeled in the Arlington area. Marta spoke on the importance of bringing together a team of professionals to review the existing conditions of the property, assess the requirements of the design and the specifics of the clients’ needs for functionality, the certifications needed to become a truly green built property and the homeowners own verification.

There were two case studies in which Marta highlighted, and Eco-Spanish Colonial and an Eco-Brick Colonial, both homes were requiring retrofitting and remodeling to different levels, but Marta and her team were able to bring these homes to higher green standards through ensuring that the homes thermal envelope was properly sealed, the mechanical systems were properly addressed and that the resources and design were addressed not only with the homeowner but thoughtfully considered through passive design. Marta spent quite some time discussing the concept that window frames in the US are not insulated window systems and that this causes a lot of energy loss. Having a third party verification system such as EarthCraft, Marta advocates is a great way to ensure that the home is sealed properly at pre-drywall. “Energy conservation strategy, especially at the windows and at the concrete foundation and insulation of crawl space and attic creates a thermos.”

What Marta means by creating a thermos out of the home is that, once you have created a very tight thermal envelope, there is a point at which fresh air needs to be introduced into the home to create a mechanical system that is healthy such as an energy recovery ventilator, or ERV. Both homes in her case studies presented had ERV systems and both were tightly sealed. The client who lives in the Eco-Brick Colonial property was at the lecture to participate in discussion: “At first I was skeptical; I wasn’t ever sure what we could even do regarding a green home… but now we absolutely love where we live.” Regarding the ERV system, she states  that it is “nice to have the fresh air coming into the home… it even smells fresher.”

The other systems such as energy efficient resource selection, i.e. the high heel trusses,  high fly-ash concrete, grey-water tanks for flushing the toilets,  and many other eco-friendly selections were discussed in more detail. The fact that Marta creates beautiful, functional, healthy homes which make her clients happy was almost appeared as  a side note to the high performance features and systems that go into these award winning homes in this discussion.

Geothermal Energy and Your Home

Tuesday, February 22nd, 2011

Find us on ProudGreenHome.com as the Green Home Gurus and join in the conversation! This was the first entry- just to get you started…

What could be more natural than using the consistency of the earth’s geothermal energy?

When was the last time you got into a discussion about green building? Did you talk about the “s” word? Sustainability? Did you happen to get into an enthralling conversation about heat loss and energy efficiency? Have you ever had to talk about geothermal energy? Well, on a flight back to the DC Metro area, I was thrilled to talk to my new found in-flight-friend about the energy efficient home he and his wife plan on building out in Lynchburg, VA. Not necessarily known for their sustainable building practices, the good folks of Lynchburg are starting to take advantage of the geothermal energy option for heating and cooling their homes.

What exactly is geothermal energy? If we roll ourselves back to 6th grade science class, some of us may remember the Greek words geo, meaning earth, and therme meaning heat, so- the earth’s heat. What’s so great about geothermal energy is that it comes straight from the earth’s core and we are able to create systems to heat  and cool whole buildings. By finding areas of constant temperature through the practice of digging down into wells and piping the naturally heated water, we can harness the earth’s own energy to sustain our heating and cooling. This is a concept as old as the earth itself (since it comes from the earth). Ancient cultures used to use water from the hot springs to bath and find warmth. In 1904 (not to say that it ancient by any stretch of the imagination) machines were experimented with such as the one found above to create electricity from geothermal energy.

My new buddy out of Lynchburg mentioned that they are not going to be drilling a deep vertical well; however they will be utilizing the technique of digging about 7-10 feet down in the earth, to where to earth is a constant temperature and creating a system of coiled tubes that will be filled with water. This is much like the radiant heating systems that people put into the flooring to heat and cool their homes. The horizontal system is much less expensive than the vertical counterpart; however does require more land space for the excavation and implementation of the coiled tubing.

The US Environmental Protection Agency, EPA, has proclaimed the use of geothermal energy the cleanest, most cost effective way to manage temperature. It is interesting to note this since President Obama announced the plan to have the US running on 85% clean energy by 2035. The US currently leads the world in geothermal energy production, with most of the deep geothermal wells being out west in California, Nevada as well as a few other locations. No matter where you are, be it Lynchburg, Virginia, or LA, there is the opportunity to discover the benefits of this clean, cost effective energy option.

Moving Toward Net Zero – Part 2 of a Series

The Energy Audit – Step One  in the Renovation Recipe

If you are reading this, you have probably already done things like switched out your incandescent bulbs with compact florescent, plugged your TV and its 500 peripheral toys into power strips, turned up or down your programmable thermostats, and made some other basic energy saving changes in your home. We will focus on some of those basic things in future articles, but for now we will take things to a different level.

Put simply, every homeowner should consider having an energy audit. This is especially important if you are considering an addition or renovation and might have access to the inside or outside of walls, ceilings, or ducts (including residing or reroofing projects) to be able to plug leaks or add more insulation.  An audit will give you the information you need to begin to turn your 1950’s Swiss cheese box into a highly efficient machine. The result should be a report that gives you specific information about where you are losing energy in your house and what actions you can take to reduce the loss.

I have to admit that energy audits were not on my radar when I began planning my addition 7 years ago. I did not have an audit performed for my house until after my renovation work was completed, when I realized it was too late to seal up some of the exterior walls of the existing part of my home. Lessons learned.

Even if you are not considering an addition or other major home improvement, an energy audit will still offer you a road-map guiding you along a series of useful energy saving improvements throughout your home.

Top 5 Things to Do or Consider Before You Start Home Renovations:

1.  Have a full Energy Audit Performed by a RESNET or BPI certified auditor who seems to know what they are doing – getting references is also a good idea.

2. Think about any walls or ceilings that you might be able to get into to make more airtight or add more insulation to during the renovation.

3.  Hire a good insulation company to make the insulation and air sealing improvements, unless you feel confident that your general contractor has experience doing this type of work (this is not too common).

4.  If replacing appliances or heating and cooling systems, choose only Energy Star rated equipment or those with equivalent energy usage.

5.  If you are married or live with a significant other, pre-order some relationship counseling for the stress that will inevitably be created in living through a renovation together.
