Lately, I’ve been really intrigued by Slow Design, which is a cousin of the Slow Food, traditional skills, and voluntary simplicity movements, and the Zen Buddhist concept of wabi-sabi. The published Slow Design Principles (Strauss and Fuad-Luke, see www.slowlab.net) are couched in academic language, and the case studies cited mostly involve the design of objects or artistic installations. However, the principles and practices of Slow Design are tools that are useful to sustainable designers, decorators, and artisans of all disciplines. To summarize (and loosely quote) that document’s main points:

Slow Design:

• facilitates ’slowness’ and provides a balance to the industrial-consumerist model of design.

• seeks to shift the user’s awareness and attitudes about materials, processes, time, and natural environment.

• reveals experiences and materials that are often missed or forgotten.

• strives for truthful, exposed use of materials and process (so the hand of the maker is visible).

• facilitates creative interaction between the user and the object or its location.

• makes users think about where the object came from, inducing contemplation & ‘reflective consumption’.

• allows the object to change, grow, or alter over time to reflect its history and usage, and continue to be used; and reflects its history prior to its current usage.

• comes from open-source, collaborative, transparent, and evolving processes.

• focuses on localness and community, through collaborations and co-design with the local community and local artisans, mapping and using local knowledge, reflecting local values & visual vernacular, and using affordable local materials, to give the finished design an authentic sense of place.

• celebrates diversity and pluralism by engaging a large range of stakeholders in the planning process. (For example, the charette process used in LEED building projects.)

• recognizes the urgent need for stewardship of the natural environment and resources, as well as honoring local knowledge and traditions, and encouraging engagement with place.

To try to illustrate what these ideas mean in everyday life, I brainstormed this list:

Slow Design is: Slow Design isn’t:

authentic                                                                    mannered, artificial, phoney

heirloom-quality                                                      semi-disposable

refurbished Victorian homes                                NeoVictorian subdivisions

modern (while respecting the past)                     like living in a museum exhibit

gardens                                                                          outdoor living rooms

rain barrels & watering cans                                     automatic irrigation systems

clotheslines                                                                  tumble dryers

timeless                                                                           trend-driven

cedar shakes                                                                 vinyl siding

handmade                                                                     machine-made

reupholstering & refinishing                                   buying new

Etsy                                                                                  Ikea

personalized and creative                                         impersonal and off-the-shelf

local                                                                                  imported

reduce, reuse, recycle                                                   buy, buy, buy

limited-edition or one-off                                            mass-produced

renewable                                                                      fossil fueled

So, what do the principles of slow design mean to you? What would you add to my list? How are you incorporating slow design into your home or decorating projects?

Reams have been written about green building from scratch, and renovations that are essentially from scratch (like gut-jobs and pop-tops). Checklists and wish-lists of eco-friendly building features and renovation practices abound, including the USGBC’s ReGreen guidelines and my own Sustainable Staging article, but what does a sustainable renovation actually look like?

This isn’t a trivial question. Reimagining existing suburban neighborhoods (as in the current ReBurbia contest from Dwell and Inhabitat, deadline for entry is Friday July 31st) is a crucial step toward building more sustainable cities. Furthermore, decreasing the environmental footprint of our existing housing stock is critical if we’re going to tackle the  anthropogenic climate change crisis. (Our buildings are currently estimated to be responsible for 35% of North American greenhouse gas emissions, with about 20% of emissions coming from home energy use.)

There’s also another factor at work. Many, perhaps most, of us North Americans purchased our current homes with a single phase of our lives in mind, intending to move from house to house as our lives changed, with return-on-investment meaning a simple extrapolation from point-of-purchase to point-of-resale. The current economic heebie-jeebies mean we have a new frame of reference. We’re thinking harder about operating costs now, and return-on-investment has come to include the payback period for installation of energy- and water-saving devices. Many of us will be living in our homes for considerably longer periods than expected. It’s no longer desirable or acceptable to treat our dwellings as disposable commodities – if it ever was.

So, in this series of posts, I’ll round up some of the most inspirational eco-reno case studies available online, ones that fit a handful of criteria. A crucial renovation goal will have to be active conservation of resources – which means doing that energy audit and implementing the auditor’s suggestions for improving your home’s insulation, but also means going deeper with energy & water efficiency measures, and when possible planning to add microgeneration to the mix. Renovating sustainably also requires minimizing our use of materials by reusing and recycling whatever materials we safely can from our existing site, and by not increasing the home’s square footage but instead using smart design principles (like those covered by Sarah Susanka’s Not-So-Big books and website) to meet our needs. We also need to renovate our homes with an eye for suitability for lifetime use, which means both durability* and timelessness, and easy & (relatively) inexpensive customization & alteration of colour and texture. I think it’s especially important to show strategies that work in cold climates, and that can be implemented a little at a time.

* Here’s a thought-provoking discussion of the pros and cons of durability in building materials.

My favorite case study that I’ve seen online (via JetsonGreen) to date is a Boulder, Colorado 1960s-era split-level, with a similar floorplan to the suburban 1970s model I grew up in, and all the changes they made are doable on a limited budget, in several stages, over time. Here’s a fairly complete list of what they did, gleaned from following all the links and studying the photos:

• not popping the top allowed renovation on a much lower budget
• the altered roofline appears to include rainwater/greywater collection as future option
• improved envelope with new windows and icynene insulation
• improved HVAC, plumbing, wiring, and lighting
• new metal siding and exterior stucco
  
• removed some interior walls to open the floorplan – but did not gut the home and start over
• (urea-formaldehyde free?) cabinetry from Ikea
• Forbo’s Marmoleum in kitchen and bathroom
• refinished oak floors with FLOR carpet tiles used as area rugs
• natural wool carpeting in bedrooms? (not sure about this, no pics)
• low-VOC paints and coatings
• recycled glass mosaic tile
• dual-flush, low-flow toilet
• Energy Star appliances
• In the photos and video tour linked from the article, the front-yard relandscaping hasn’t been completed. I’d expect that they’re doing permaculture, and probably facing the concrete planters with reclaimed brick to match the rest of the home.

JetsonGreen also profiled a more ambitious (LEED Platinum!) green gut-renovation of an 1959 home in Portland, Oregon, including geothermal and solar PV, and moving an internal staircase. As part of the renovation, they replaced the windows, reinsulated, added an air exchanger, and used FSC-certified wood and Energy Star appliances. (I’m pretty sure those are Bedrock’s Blazestone recycled-glass tile used as the kitchen backsplash. Yum.) LEED-for-Homes-certified renos are almost always going to be gut jobs, since they need to have their outer envelope exposed from either the outside or inside to meet LEED’s stringent documentation requirements, and it’s often easiest to do both. But, as Preston writes, this house offers some great lessons:

Just look at the before and after photos of this green home and you’ll see a couple critical renovation strategies: (1) get rid of water-sucking grass without making your landscaping look crazy, and (2) keep the same size and scale of your home rather than building it into a monstrosity.

Green Building Advisor also profiles similar LEED-certified green renovations from time to time, like this gut renovation of a 19th-century home in Ann Arbor, Michigan. For this renovation, the team reinsulated, replaced windows with argon-filled low-e models and exterior siding with fiber-cement siding, and installed a ground-source heat pump and a tankless hot water heater. A small addition was built using ICF blocks, and the lot was relandscaped using permeable paving and rain and vegetable gardens.  I found the reuse of wood (salvaged from walls removed during the reno) to build the new floating staircase really inspiring.

But it really isn’t necessary to gut-renovate a home in order to do a deep energy retrofit. I was fortunate to see a local renovation of a 1949 stucco bungalow typical of many of Edmonton’s inner-ring postwar suburbs on the 2009 Eco-Solar Home Tour, and the owners have also documented their renovations year-by-year online. To summarize what they did:

• installed geothermal heat pump, and relandscaped
• replaced aging water heater with efficient solar (not tankless) model
• installed heat recovery ventilator
• improved envelope with argon-filled vinyl windows, new doors, blown-in cellulose insulation, new roof, draftstopping membrane
• LED lighting in backyard that runs off a solar panel on the detached garage

Also via Green Building Advisor, this is a 1970s ranch home in Boulder, Colorado that has undergone a deep energy retrofit and the addition of solar PV and hot water on the roof to create a net-zero-energy home. Impressive.

Finally, I’d like to call attention to the Humphrey House blog from Chicago, Illinois. The La Fleurs have been gradually renovating their 1912 Craftsman bungalow to an eco-envy inducing state, without sacrificing its historic character (swoon) or overspending, have done most of the work themselves,and have blogged every step of the way. Their home now features tubular skylights, salvaged interior doors and appliances, water-efficient fixtures, low-VOC paints and stains, Zodiaq recycled-content kitchen counters, soy-foam insulation, a tankless water heater, and an air recirculation system (a complete list of their green features as of last Sept is in this post). Their current project is relandscaping their backyard to include a veggie garden, reclaimed-concrete pavers, compost area, and more rain barrels. Oh, and do you notice what’s not in the list? Expensive big-ticket items like solar PV or hot water, or geothermal heating.

Now that’s inspirational.

What eco-renovations are you planning for your home?

Staging has revolutionized the real estate industry by maximizing homes’ appeal and potential, drawing attention to selling features, and helping buyers to imagine the home as their own, so that homes are shown at their absolute best. Similarly, a green revolution is now sweeping new home builders as public awareness of global environmental problems, indoor air quality issues, and the need for energy and water conservation has become the new norm. The importance of this movement is underscored by recent estimates that our buildings are currently responsible for 35% of North American carbon dioxide emissions, and improving them will be the quickest and cheapest way to reduce North America’s impact on climate change. Sustainable staging brings the green revolution to the real estate resale market.

This is excerpted from my article, Sustainability and Staging (PDF), which introduces the principles of sustainable design, outlines the benefits of applying them in a real estate staging context, and provides a detailed checklist for decorators, redesigners, and stagers to use in greening their staging practices.

I am thrilled that this article will be incorporated into redesign and staging training provided by CRDA instructor Val Sharp. It is my wish that it be freely shared among interior decorators, redesigners, and stagers, so that sustainable best-practices will be quickly adopted within our industry.
