Air leakage, or infiltration, occurs when outside air enters a house uncontrollably through cracks and openings. Properly air sealing such cracks and openings in your home can significantly reduce heating and cooling costs, improve building durability, and create a healthier indoor environment.
What will happen to that water bottle you just tossed into your recycling bin? According to Mohawk Industries, manufacturer of EverStrand carpeting, “One in every four plastic bottles recycled in North America becomes EverStrand."
Vancouver models much of its urban planning on the principle of eco-density, a term developed largely by City Councillor Suzanne Anton. There was no better place for us to interview Suzanne than at the Coopers Pointe on the waterfront looking across toward the Olympic Village. While in Vancouver, we wanted not only to cover the Olympic architecture but to grasp the essence of a city which is reputed for its very low ecological footprint per capita. It is no coincidence, I believe, that William Rees and Mathis Wackernagel developed the concept of an ecological footprint at The University of British Columbia.
On Tuesday of this week, President Obama announced construction plans for the first new U.S. nuclear power plant (actually two new reactors at an existing plant) in almost three decades. Touting the benefits that nuclear power offers to the environment (in particular, fewer carbon emissions as compared to similar-sized coal burning plants), the U.S. government will back $8.33 billion in loans for the reactor additions to the Alvin Vogtle Electric Generating Plant in Burke, Georgia. The loans program is run by the U.S. Department of Energy (DOE) and has previously sponsored infrastructure projects concerning wind turbines and cleaner coal burning power plants.
Our trip to Vancouver was intensely successful. However, as I subtly suspected, the content we ended up with was not exactly the type of content we had initially intended to gather.
Designing and Installing a Safe System
Almost every commercial and public building, whether it is an office building, sports arena, place of worship, or school building, contains a guardrail system. Guardrail systems are installed to provide safety and protection for the building occupants and are placed at or near the outer edges, of flights of stairs, ramps, landings, platforms, balconies and accessible areas of roofs. They will also be found at the perimeter edge of any opening or accessible surface, such as an opening for a stairway, or at a location where operating conditions require limited access to a designated area in order to guard against accidental falls.
Bathroom vanities are comprised of a base or furniture cabinet, a countertop mounted to the top of the cabinet, a sink, a faucet, and a drain stop assembly located at the bottom of the sink which allows water to drain or be collected. Maintaining each component can be overwhelming, given that there are several different styles, manufacturers, and types of materials used. However, there are only a few components that require regular inspection and/or maintenance to ensure proper function.
The Opening Ceremony of the Vancouver 2010 Winter Olympics evoked a sense of awe in Carla D'Errico, freelance writer of travel and architecture, who gives her response to the ceremony in an interview below. In short, the artistic directors David Atkins and Ignatius Jones deserve the highest esteem for their spectacular video arts show. In addition, while the Olympic torch may seem to be of little consequence when it comes to sustainability, the Vancouver 2010 Winter Olympics Torch that kicked off the ceremonies on Friday night is actually a remarkable example of green ingenuity.
In 1978, municipal, provincial, and federal Canadian governments began working together to plan the development of a convention center – complete with cruise line and hotel amenities -- on a waterfront property in Vancouver that had been used earlier in the century as a railway pier.
At 7:30 a.m. on a winter Saturday, a time when most kids are still sleeping, professional-looking seventh and eighth graders were already buzzing around pushing carts that were loaded with table-sized futuristic city models and getting them into place for a day-long judging process. The projects that these students were rushing about represent hours of thinking, designing, researching, and collaborating with mentors and classmates to create: An Affordable Living Space For People Who Have Lost Their Home Due to a Disaster or Financial Emergency.
The tragic explosion at the Kleen Energy plant in Middletown, CT on February 7th reminds us that construction is dangerous work. Our sympathies go out to the families of those impacted by this recent accident. The explosion apparently occurred while the crew was purging natural gas lines. A nuance of this story is that this power plant was still under construction and not yet operational. Also, there’s been debate in various blogs and news articles about potential fatigue among the construction crew. Were they under too much pressure to get too much done too quickly?
Three recessed ceiling light fixtures flood the fireplace in our family room. Sometime after we moved in, the dimmer switch that controls the lights stopped functioning properly. It turned the lights on and off, but did not dim them. We were not concerned with our inability to dim the lights and affect the mood of the room because the light bulbs' brightness at that time was not an issue. Recently, we started replacing our incandascent light bulbs with compact fluorescent light bulbs (CFL). The CFL bulbs we purchased have a higher lumen output than the incandescents, resulting in a brighter light. It was now time to solve our dimming problem.
