In an attempt to enhance the quality of construction with regards to energy efficiency, economy, Drummond House Plans proposes a new and innovative approach to ecologically and ergonomically designed house plans that include pertinent details on how to achieve an Environmentally Superior home or chalet.
Case in point, plan 2939-ES, whose details include specifications on optimal orientation to inhibit the harsh rays of the sun in the summer and benefiting from this passive heat source in the winter months while taking maximum advantage of the surrounding panoramic view. Learn invaluable ways to plan your landscaping to make full use of rain water, shade benefits of some trees and wind breaking characteristics of others.
Discover the best ways to make use of the ever increasing number of “recycled” construction materials and be assured that your contractor uses the best practices when it comes to recovering the inevitable waste materials from your project.
Environmentally Superior designs include details about construction methods using low V.O.C. (volatile organic compounds) and the installation of the best suited HVAC components to ensure a healthy living environment with optimal air quality and humidity management.
Details of how to reduce energy consumption start with the construction methods used for the foundation and extend to choosing the best appliances and appropriate lighting. Certified fixtures, such as an on demand water heater, can contribute to energy savings by limiting excessive consumption of this costly resource.
To enhance the aging in place aspect of this home, plan 2939-ES is designed for day to day living on the same level. The main floor boasts an entrance foyer, a kitchen with a movable island, a living/dining room complete with cathedral ceiling and place for a fireplace or wood burning stove. The master bedroom is complete with a private bathroom and a laundry area close by.
Another thoughtful aspect of this design is the 4’ wide hallway and a linear staircase that can be fitted with an elevator to access the second floor if need be to adapt the home for a mobility restrained occupant. The bathroom in the master bedroom can be fitted with all of the required security features in the event that this becomes necessary.

Discover 3240-ES, designed with the same concept in mind, we look forward to hearing your comments about this new trend in more livable homes!

Today is World Water Day and it just so happens that Jerry Yudelson, noted green building authority and author, has released a new conceptual tool to help people understand where water will come from in the future.  The tool mimics the popular Pyramid of Conservation used by Minnesota Power and explains water sourcing in ten increasingly expensive and complex steps.As shown at the base of the pyramid, it’s easy and relatively cheap to use less water.  It’s a lot more complicated and expensive to desalinate ocean water for human consumption. 

Here are the ten steps:

  • Behavior – education, audit, water pricing, conservation, construction codes
  • Low-cost/no-cost – leaks, aerators, low-flow showerheads, shower timers
  • Irrigation – native or adaptive landscape, drip systems, web-based irrigation, sub-metering
  • Hygiene – retrofits, low-flow toilets, water-free urinals, rebate programs
  • Appliances – dishwasher, clothes washer, water softener
  • Extreme Makeover – compost toilets, hardscape, no irrigation, on-site black water reuse
  • Water Heating – solar water heating, hot water loop, efficient water heater
  • On-site Reuse – rainwater collection, gray water, irrigation
  • Off-site Reuse – sewer mining, purple pipe systems
  • Desalination, New Water Sources

Of course, some of these can be done at home (i.e., retrofits, water-saving appliances, water heating), while require a larger effort (i.e., desalination, off-site reuse).

Water is a precious resource that must be protected, and this is a primer to get that started.  All in all, this is a straight-forward, dead-simple graphic that can help us evaluate how to do that.

Would you water your garden with what goes down your shower drain or out your washing machine? In Tucson, Arizona, and an increasing number of water-starved western cities, more and more residents are saying yes.

If you’ve never contemplated what happens to the water that gets you or your clothes clean, you’re far from alone. But for cities and environmentalists trying to head off the growing threat of drought and rising water costs, so-called graywater — differentiating it from the “black water” that goes down the toilet — is getting a lot more attention. A decade ago, Tucson, which has about a million residents in its metro area and is a liberal and environmentally conscious oasis in a red state, convinced Arizona legislators to make it legal for homeowners to irrigate their trees and plants with the water that was going down their drains or out of their washing machines without a permit. Now, graywater use is not only legal in Tucson, and indeed the rest of Arizona, but promoted, and, in some cases, required. In 2007, the state rolled out a tax credit of up to $1,000 for homeowners who install graywater systems. Last year, a law — believed to be the country’s first — went into effect in Tucson that requires builders to include graywater plumbing in new construction.

Whether by conscience or necessity, many people are looking to reduce their water consumption. The perfectly manicured emerald lawn may certainly look lovely but normally requires a great deal of work, chemical intervention and labour. If you stopped pampering your golf green, nature would inevitably take its course and take over and balance the space. Somewhere between the two, is a solution to provide a landscape that is visually pleasing, yet sustainable.

Xeriscaping and xerogardening refers to landscaping and gardening in ways that are more sustainable, consuming far less or no water for irrigation. As with many gardening techniques, you will go through processes of trial and error but the end result is a landscape or garden which is actually far less labour intensive.

The word xeriscaping is a portmanteau of the Greek word xeros (for “dry”) and landscaping. It quite literally means landscaping with minimized water use.

Alternate terms that may be used are water-conserving landscapes, drought-tolerant landscaping, zeroscaping, smart scaping, or dry gardening.  The use of plants that tolerate local climate conditions is emphasized.

Xeriscaping is fairly common-sense actually. It is an intuitive way of dealing with the hand that nature deals you rather than creating an artificial environment.

1. Plan and design
As with most landscape plans, start with a diagram, drawn to scale, that shows the major elements of your landscape, including house, driveway, sidewalk, deck or patio, existing trees and other elements.

Then think of the functionality of your design. Do you need space for dogs to run? Children to play? Curb appeal? Create privacy? Frame or screen views? Create a conceptual plan (bubble diagram) that shows the areas for turf, perennial beds, views, screens, slopes, etc. Once finished, develop a planting plan that reinforces the areas in the appropriate scale. If you are having a difficult time with this process, contact local greenhouses or horticulture societies for possible referrals of landscape designers.

2. Soil amendment
All plants will benefit from the use of compost, which will help the soil retain water. If you are blessed with adequate organic material, you can create your own. Alternatively, there are many sources where you can buy composted waste (greenhouses, farmers, landscape materials, etc.)

3. Efficient irrigation
Xeriscape can be irrigated efficiently by hand or with an automatic drip or sprinkler system. If you choose to include turf areas, these should be zoned separately from other plants to allow the most efficient irrigation of each type of planting. For grass, gear-driven rotors or rotary spray nozzles that have larger droplets and low angles to avoid wind drift. Spray, drip line or bubbler emitters are most efficient for watering trees, shrubs, flowers and groundcovers.

Note: The most efficient sprinklers release big drops close to the ground rather than misting or throwing the water high in the air.

Deep, infrequently watering develops deep roots. Evening or night watering reduces water lost to evaporation. Automatic sprinkling systems should be adjusted monthly to accommodate weather conditions and the installation of a rain sensor will prevent irrigation when it rains.

4. Appropriate plant and zone selection
Common sense time… To minimize water waste, group together plants with similar light and water requirements, and place them in an area that matches these requirements. Moderate-water-use plants fair well in low-lying drainage areas, near downspouts, or in the shade of other plants. Turf requires the most water and shrub/perennial beds will require approximately half the amount of water. Dry, sunny areas support low-water-use plants. Planting a variety of plants with different heights, color and textures creates interest and beauty. Don’t forget about incorporating indigenous plants. They will thrive with little or no fuss!

5. Mulch
Mulch cannot be underestimated. It keeps plant roots cool, prevents soil from crusting, minimizes evaporation and reduces weed growth. Organic mulches, such as bark chips, pole peelings or wood grindings, should be applied 2 to 4 inches deep. Fiber mulches create a web that is more resistant to wind and rain washout. Inorganic mulches, such as rocks and gravel, should be applied 2 to 3 inches deep but use this practice with caution as it makes the area hotter.

6. Alternative turf
Many native grasses (warm-season) have been cultivated for turf lawns. Find like-minded people in your area and benefit from their experience and preferred blend. Warm-season grasses are greenest in June through September and straw brown the rest of the year. “Grass gardens” can also be a lovely addition to your landscape scheme as they come in a variety of heights, textures and colours and can provide lovely four-season interest.

Native grasses (cool season) such as bluegrass and tall fescue, are greenest in the spring and fall and go dormant in the high heat of the summer. New cultivars of bluegrass, such as Reveille, and tall fescue, can reduce typical bluegrass water requirements by at least 30 percent. Fine fescues can provide substantial water savings and is best used in areas that receive low traffic or are in shady locations.

Use the appropriate grass for your selected area and limit the amount of grass to reduce the watering and maintenance requirements.

7. Maintenance
All landscapes require some degree of care during the year. Turf requires spring and fall aeration along with regular feeding every 6 to 8 weeks. Keep your grass height at 3 inches and allow the clippings to fall. Trees, shrubs and perennials will need occasional pruning to remove dead stems, promote blooming or control height and spread. Much of the removed plant material can be shredded and used in composting piles. Just avoid composting any weeds that have gone to seed. They will come back to haunt you!
