Ontario's 1st LEED Platinum Green Building

  • Architect: Montgomery Sisam Architects Inc.
  • located in Vaughan, Ontario
  • 2-storey, 1095 m2 building: office space for 25 occupants and a works garage
  • construction is engineered wood framing with brick and wood siding

  • concrete “earth tube” delivers outdoor air to the basement mechanical equipment
  • 2 heat-recovery ventilators deliver 100 % outside air to the offices via displacement ventilation
  • power: partly by photovoltaic system and remaining needs buying electrical power from a supplier of green (renewable) power—Bullfrog Power
  • composting toilets (rarely used in offices) and waterless urinals means that the centre uses no water for wastewater conveyance, , together with low-flow plumbing fixtures throughout the building conserve 80% of the potable indoor water normally used in a building of this size

Sources for green furniture (Green Home Guide)

Question: Are there any stores—online or in the real world—that sell affordable green furniture?

Answer: Fortunately, there are—both online and in the real world! Of course, which ones you buy from will depend on what you consider affordable and which green attributes are most important to you.

Depending on the materials used to make a piece of furniture, its green features could include any of the following:
* Forest Stewardship Council (FSC) certified, sustainably harvested wood;
* nontoxic glues (or no glues);
* nontoxic stains and finishes;
* organic cotton or other natural fibers;
* untreated upholstery or nontoxic fabric treatments for fire resistance, waterproofing, and stainproofing; and local manufacture using local materials.

While it’s rare to find products that meet all these criteria, the number of furniture manufacturers and individual products with green attributes is growing, providing more options in all price ranges... (read more by following the link)

High Efficiency Toilets (HET)

"Thus, the High Efficiency Toilet (HET) is becoming a significant part of the toilet fixture marketplace as manufacturers recognize the compelling need for water-efficient products and water authorities and municipalities incorporate them into their toilet replacement programs. Furthermore, builders participating in "green building" programs, such as the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) and The Metropolitan Water District of Southern California's California Friendly Model Home program install HETs to accumulate water efficiency credits or to comply with program requirements.

The HET is defined as a fixture that flushes at 20 percent below the 1.6-gpf/6.0-lpf maximum or less, equating to a maximum of 1.3-gpf/4.8-lpf. This 20% reduction threshold serves as a metric for water authorities and municipalities designing more aggressive toilet replacement programs and, in some cases, establishing an additional performance tier for their financial incentives (e.g., rebate and voucher programs). Previous field studies in the U.S. and Canada have demonstrated that the average flush volume of dual-flush toilets in residential applications ranges between 1.1 and 1.2 gals."
