The Living Wall

Posted by Jay Somerset

Last week Toronto hosted the Green Living Show, a consumer show featuring everything from greywater irrigation systems to renewable energy (solar, wind, water) to food made from organic ingredients. In other words, everything you need to live the eco existence, including a keynote address by none other than Bill Clinton, who headlined with top tips for living green.

Mixed in with the usual contenders—chemical-free cleaning supplies, organic sauces served up with pretzels (what show would be complete without these freebie stalls?), the seemingly un-ironic car companies touting their hybrid vehicles—was a single vendor selling a basic, low-tech idea: The Living Wall.

Like any wall system, The Living Wall acts as both a privacy screen and a noise dampener, except instead of being built out of synthetic materials (brick, steel, iron) this wall is made from willow shrubs that grow quickly, is easy to maintain (the stalks keep their shape and don’t require special watering) and are hardy enough to survive the both the heat of Houston and the frigid wrath of Winnipeg.

The concept behind The Living Wall is quite old, derived from the basic recipe of combining two-year-old willows with wooden posts, which provide stability and force the shoots to project upward and straight. The Wall can be as long as you want, planted as a single line or in rows for added privacy, or in combination with other organic wall systems (see more pictures here). Willows have a lifespan of about 30 to 40 years, so replanting is necessary; other than that, the only maintenance required is gentle trimming.

Completely organic and graffiti-proof, this carbon-dioxide absorber establishes itself quickly, blends in with nature and is cheap to build and maintain—clearly a winning combination when it comes to landscaping.

Light Bright

Posted by Jay Somerset

Most of us know the benefits of using compact fluorescent light bulbs instead of traditional, less-efficient incandescent bulbs. Compact fluorescents last up to 10 times as long as incandescent bulbs and use far less energy, making them the right choice for the earth and your pocketbook.

Compact fluorescents work by passing a current through a tube filled with a trace amount of mercury and argon gas, an inert, colourless, odourless and nontoxic gas. If you’ve ever purchased windows, you know the benefits of argon gas: reduced heat loss in winter and decreased heat gain in summer.

When I was a kid I thought argon gas was some sort of Superman-strength fume that protected against, I don’t even know, aliens? Turns out I was partly right; the gas does have superhero strength, as in light force.

Luxim, a company that specializes in developing high-efficiency lighting, recently revealed its newest project: a Tic-Tac-sized bulb that gives off as much light as a streetlamp but is ultra-efficient thanks to, you guessed it, argon gas, as well as a component called a “puck.” When electrical energy is delivered to the puck, the puck acts like an electrical lens, heating up the argon to a temperature of 6000 degrees Kelvin, and turning the gas into a plasma that gives off light.

Conventional light bulbs and high-end LEDs get around 15 and 70 lumens per watt, respectively. By comparison, the plasma bulb uses 250 watts, and achieves around 140 lumens per watt, making it incredibly bright and highly efficient in its light distribution.

So while you might not need such bright lighting in your home, this tiny bulb offers a brilliant glimpse into the future.

Green Your Home, Part 3: Appliances

Posted by Jay Somerset

Back in the 1950s, homeowners were inundated with ads, like this one, depicting pretty housewives using state-of-the-art home appliances. The home became a symbol of post-war affluence modernized with dishwashers, dryers, ovens, vacuums and other timesavers promising to make life easier. Those were the days … days of inefficient, energy-guzzling machines. We’ve come a long way, baby. Demand for energy-efficient appliances has increased, which means prices have dropped on once-costly items such as high-efficiency furnaces.

So, how do you tell the good from the gimmick when it comes to green appliances? In North America, the easiest way to guarantee you’re buying an efficient, third-party-verified machine is to look for the Energy Star label. Energy Star is an internationally recognized rating system that tests products for energy efficiency. Products range from building materials (windows, doors, insulation, ventilation) to appliances to lighting. Some states and provinces offer rebates for Energy Star purchases.

Outdoor Green Gear

Of course, green appliances aren’t only found indoors; preparing for the springtime rush, retailers are now pushing eco-workhorses for the yard. Forget gas-guzzling mowers; Solaris’s cordless, solar-powered mower can cut up to 10,000 square feet on one battery charge. Simply mount the solar panel on your shed’s roof and get cutting. Retail value: $569.

Solaris mower

Black & Decker allows you to mow and mulch–leaving behind grass clippings (rather than bagging and composting) that function as lawn fertilizer and reduce the need to water–with their Cordless Mulching Mower, which runs on a rechargeable 24-volt battery. Retail value: $500.

Black & Decker also makes other cordless yard tools such as hedge trimmers (about $100) and tree pruners (same price).

Super-recycler TerraCycle Inc. sells oak rain barrels for collecting rainwater for watering plants, lawns, and so on. Simply place the barrel under your gutter’s downspout and turn April’s showers in May’s flowers. Retail value: $150.

Terracycle Oak Rain Barrel

Of course, this is just a small sampling of green appliances for your home. Virtually every home category is jammed with green products, so look for the Energy Star label and read the fine print. You can find the products above at the Home Depot, and other large retailers across the continent.

Green Your Home, Part 2: Indoor Air Quality

Posted by Jay Somerset

By now, global-warming naysayers are fringe folk who probably also believe the world is flat. We know the benefits of recycling, and energy efficiency has become the buzzword in home building and renovating. Your highly efficient stove and windows may cost more upfront, but the real savings—and your home’s resale value—come through reduced energy bills and increased life spans while also helping make the planet a better place.

But green building isn’t just about the planet—it’s also about the health of the homeowner. Newly renovated homes often have that “new car” smell, which is really a stew of volatile organic compounds (VOCs) often found in oil paint, as well as formaldehyde off-gassing from engineered wood, like the medium-density fibreboard (MDF) used to make kitchen cabinets and furniture.

According to the Canadian Mortgage and Housing Corporation, indoor air quality—especially in tight, new homes—can be three to four times more polluted than outdoor air, which may be the reason 20 per cent of North Americans have some form of lung disorder, likely linked to dust and mold in your home. We spend an average of 90 per cent of our time indoors, either at work or at home, so eliminating VOCs is crucial.

Luckily, homeowners today have options not readily available even five years ago. Most paint, for example, is virtually VOC-free, and engineered wood such as MDF is now available without formaldehyde. For flooring, CMHC recommends hard surfaces, such as prefinished hardwood flooring, or ceramic tiles laid down using a low-toxin grout. The reason: hard surfaces are easier to clean, they don’t collect dust as easily as carpet and they are last longer, which means, beyond better air quality, you’re also reducing repair costs and trips to the dump to plonk worn-out carpet.

The U.S. National Institutes of Health website includes a page dedicated to household products and toxins. Click Products and then choose Inside the Home (for bathroom, kitchen, etc.) or Home Maintenance (for grout, insulation, paint, etc.).

Still unsure how indoor air quality relates to you or how you can easily reduce harmful VOCs? Health Canada has a section containing information, resources, and even a few quizzes to help you get your air quality where you want it to be.

Green Your Home, Part 1: Comparing Cost

Posted by Jay Somerset

Five years ago, “green” renovating meant three things: increased costs, questionable quality and searching through pages and pages of contractor listings till, eventually, you found a contractor knowledgeable about green building that didn’t also charge the moon. It wasn’t easy being green, but that was then and this is now.

Today, none of these statements ring true: green building materials have increased in quality while decreasing in cost as consumer demand for environmental products and systems keeps climbing. What’s more, environmentally responsible products save you money over the long haul because of increased efficiency and longer life spans; it may cost you slightly more upfront, but you’ll quickly earn back your investment while also upping the resale value of your home.

But don’t just take our word for it. Even Wall Street, traditionally weary of any shade of green other than the dollar bill, agrees: green building is both responsible from an ecological perspective, but also beneficial from an investor’s point of view. Investor website TheStreet.com takes a look at green building from a cost/benefit point of view.

Similarly, CNN’s Money Magazine takes a hard look at green reno costs and return on investment.

Incentives

Still not convinced green renos suit your budget? Well, perhaps the state can help change your mind. Governments across North America are trying to cut back on energy and water consumption, so it’s in their best interest to entice homeowners to go green, which means a plethora of grants, incentives and rebates. American rebates take the form of everything from tax breaks to grant programs, while the Canadian version is pushing energy audits various government rebate programs.

Design trends

Posted by Jay Somerset

The 10th annual Interior Design Show was held a few weeks ago in Toronto, and although the bitter cold has turned everything snow white, the real colour of choice this year is, you guessed it, green.

IDS 08 featured a seminar on the benefits of sustainable design, from your home’s mechanical systems (heating, cooling, ventilation) to design (passive solar) to furniture and fixtures. Sustainability permeated every corner of interior design, as shown by the new products on display at the show.
Luckily, you didn’t have to come to Toronto to find these goods. Here’s a sampling of the new, the cool, the green.

Rad Rads
Belgian manufacturer Jaga has transformed boring—albeit efficient—radiators into objets d’arte. First there’s Angula Plus, which, unlike a traditional rad, fixes around 90-degree corners with a thin width that makes it perfect for small spaces, such as entranceways and bathrooms. But it’s the Heatwave (pictured below), designed by Joris Laarman, that will cause your head to spin.

Unbeatable Underfoot
Forget hardwood flooring and look to its evolution with Plyboo, a laminated bamboo material that can be used for flooring, paneling and plywood. Plyboo has been recognized by the Leadership in Environmental Design (LEED) certification system for its durability, and its composition from 100 per cent bamboo grass means the resources used can be replenished without needing to replant them.

Let it Flow
American Standard’s new FloWise high-efficiency toilet is the Cadillac—the Michael Caine—of toilets. Not only is it stylish and easy to clean (if there’s anywhere for an anti-microbial surface, it’s definitely the toilet)it also uses 20 per cent less water than standard, 1.6-gallon-per-flush toilets, and comes with a 10-year warranty.

Rock On
South African designer Ronel Jordaan has taken our fixation with fixing the planet and turned it into rock—well, soft—solid comfort. 100 per cent wool rock-shaped cushions and pebble carpets contain fibres that link when rubbed together, bringing nature inside, while keeping things comfy.

Compact fluorescent light bulbs

Posted by HRG Blog

Compact fluorescent light bulbs should be a part of the total strategy for energy efficiency in your home.

One of the biggest trends in the last 20 years is how to save energy through lower power consumption. And of course, lighting is one of those critical energy wasters for many homes, regardless of their size. It takes a certain amount of electrical energy to light an average person’s home and great reductions can be made. By now, most people know this is a reality with compact fluorescent light bulbs, where energy reduction can be as much a 75% with a corresponding reduction on your electric bill. But there is often some sacrifice that still has to be made when it comes to lighting with compact fluorescent light bulbs. There may be a couple of ways to better incorporate this technology into energy savings in your home in concert with other efficient lighting.

In people’s homes, lighting serves many different purposes, from reading to kitchen tasks to lighting general areas such as bathrooms or a family room. Because there are so many different activities that go on in the home, it’s important not to take the approach of one-size-fits-all when it comes to lighting. But that’s the way many people approach energy efficiency in their home, outfitting the entire home with compact fluorescent without thinking about what they might be doing in those individual spaces. It can be a tricky balancing act between what looks good aesthetically and what is a true energy-saving opportunity. Another aspect that comes into play many times is that people need to do some kind of dimming or other kinds of lighting control, which doesn’t always work well with energy-saving compact fluorescent lights. So it’s good to come up with an integrated strategy that might work best to accomplish energy efficiency in a home.

Probably the biggest thing to keep in mind when it comes to compact fluorescent lighting is that the standard off-the-shelf compact fluorescent is not a dimmable product. If you have a system that does dimming in your house, it can be difficult to incorporate compact fluorescent so that it will look as good as standard incandescent lighting. If you’ve gone to all the expense to have a dimming system with scenes and total lighting control, then almost no compact fluorescent is really going to be the ultimate solution. In cases like that, it makes sense to use that lighting control system and keep lights shut off when they’re not being used. Many times, you can incorporate occupancy sensors that will shut off the lights when nobody’s in the room and that can be used in a complete lighting control system.

If you just have a few dimmers on the wall, you can use some dimmable compact fluorescent light bulbs that will dim down to lower light levels, making it acceptable in many situations. There are some that go down to 20% of full light output, and then there are others to go all the way down to about 1 or 2%. These can be used in standard incandescent dimmers that you might have on the wall in your home. That can take care of some of the dimming that you need, while other on-off circuits can be handled by standard compact fluorescent for maximum energy savings.

It might also be a good time to think about what you are using for track lighting, or recessed lighting. If you have standard incandescent lamps, they could be replaced with halogen bulbs at a lower wattage. In many cases, this is a better way to handle energy efficiency while still getting the correct lighting effect through dimming or display. Halogen technology has improved much over the past 10 years and it’s a good solution to reduce energy, even though it won’t save as much energy as a fluorescent light bulb. Most people like the way halogen illumination looks, with its white, crisp light that really does a good job for many types of track lighting.

To put it simply, you should look for areas where you can use compact fluorescent lights without hurting the aesthetic aspects of your home. In places where you still need to have a dimming capability or greater lighting control, you may want to incorporate halogen as a part of your total strategy. You may also be able to incorporate some new LED lighting that has a very low wattage and still provides a fair amount of light for many different kinds of tasks. It may not be able to replace the higher wattage of either halogen or fluorescent, but it will provide light for an area and can be used as part of that total scheme for reducing energy. Take a look at how you use lighting in your home and think about what you want to accomplish with light, because that’s still the ultimate goal, to have your home lit in a pleasing manner. Apart from energy savings, that’s still the main purpose of light and if you miss that, no amount of energy savings is ever going to make you feel better about a lit space that isn’t quite right.

Finances: Renovations with Returns

Posted by HRG Blog

When considering a home renovation to improve the resale value of your home, keep in mind what has the highest return on investment (ROI).

Bathroom and kitchen renovations seem to still lead the market place with ROI. Painting either the exterior and interior or upgrading the floors will pay for itself in value. Renovating the basement, creating a recreation room, or building a garage to add square footage all offer a high resale value. Installing a fireplace, replacing windows and doors, installing central air and improving the heating and furnace system will all appeal to the energy-conscious buyer and also offer better pay backs at selling.

Working on your landscaping is always recommended, but be a minimalist as this is not the area to gain your ROI. Adding a skylight may seem like a good alternative to light your home, but for resale it has the same returns as using energy-efficient bulbs.

Set out a budget, the amount you are willing to invest to get a higher price for your home. Talk to a professional who is able to assist with improving your home, as well as your real estate agent. Your agent should be able to tell you exactly what your house needs to get the highest ROI. Then, decide which areas you are going to focus on and start the process.
