Since early 2009, the Consumer Product Safety Commission (CPSC) has been contacted by more than 1,000 residents of 27 states, Puerto Rico and the District of Columbia about possible chemical emissions from imported drywall that was used when their homes were built or remodeled. Most calls were from persons in Florida, Louisiana, and Virginia.

At this time, experts believe that defective drywall imported from China was installed in homes built or remodeled after 2003.

The number and location of all affected or potentially affected homes are not yet known.

CPSC is leading the federal investigation into complaints about imported drywall. The Centers for Disease Control and Prevention (CDC), the Agency for Toxic Substances and Disease Registry (ATSDR), the U. S. Environmental Protection Agency (EPA), and the
U.S. Department of Housing and Urban Development (HUD) are providing technical support to CPSC and several state health departments. CDC and ATSDR are working with other federal and state agencies to identify what chemicals are in the drywall and if these chemicals are a health risk to persons living in homes containing this drywall.

How can I find out if my home has imported drywall?

Corrosion: Are any of your home's copper pipes, plumbing fixtures, or uninsulated electrical wires at light switches or receptacles corroded? Have your air conditioner evaporator coils failed early? Metal or copper corrosion of these types may mean there is defective drywall in your home.

Odor: Does your home have an odor that smells like rotten eggs, matches, or fireworks? A sulfur odor in the home might mean defective drywall is present.

Label: Can you see the back side of your drywall? Some drywall from China is stamped with "Made in China" on the back. However, some Chinese drywall does not have a label or markings.

The Florida Department of Health developed a guide for residents to help them identify drywall problems.

What has been found in the air of homes that contain imported drywall?

State and federal agencies are testing the air inside some homes in Florida, Louisiana, Virginia, Alabama, and Mississippi. They are testing homes in which homeowners suspect they have contaminated drywall and, for comparison, other homes in which no problems have been reported. State and federal agencies will evaluate these results to determine whether there is a health problem. This evaluation is expected in the fall of 2009.

How can Chinese drywall affect my health?

Some persons are more sensitive than others to possible chemical exposures. An exposure that causes no problems for some people can make other people sick or uncomfortable. Persons most likely to get sick from breathing contaminated air include the elderly, children, and people with asthma, allergies, lung disease, and heart problems. Until federal agencies get more information from the indoor air testing, it is not possible to determine if the symptoms people are experiencing are possibly from drywall.

What else should I do if I may be having health problems from imported drywall?

See or call a doctor if you are experiencing health problems and say that you are concerned your illness might be related to imported drywall. Tell your doctor about the health care provider fact sheet for imported drywall. A fact sheet from CDC tells your health care provider how to get more information.

• Go outdoors to get fresh air. Scientists do not know what, if any, benefit there is to opening windows to allow fresh air to come into the home.

Are there other problems I should watch for in my home that may be related to imported drywall?

• Some homes with imported drywall have had damage to exposed wiring. We do not know of any house fires that have occurred related to the drywall. If you experience unusual electrical problems in your home (such as appliances or light switches not working), ask a licensed electrician to check out the problem.

Where can I get additional information?

Is remodeling the solution for reducing an office's energy consumption...and costs?  According to a study by energy efficiency company, Johnson Controls Inc.,  there are ways to save energy, and ways to "think" you're saving.  They took a look at the effect workplace comfort has on employee productivity and energy conservation.

"Employers may be tempted to turn down the thermostats this fall, but this quick fix could lead to hidden costs," said Clay Nesler, Johnson Controls' vice president. "Energy efficient systems and equipment is the win-win alternative, allowing businesses to save energy and money without sacrificing workplace productivity."

• 69% of the 800 US office workers surveyed for the study said they are "willing to sacrifice" their preferred ideal temperature on the job if that helps conserve energy.
  
• 45% said they think their employers are not doing enough to make their offices more energy efficient.
• 78% of workers said their productivity falls when they feel too cold or too hot at the office
• 98% said their offices are too hot or too cold at some point.

Solutions to Workplace Comfort

The study found that as a result

• 49% said they use a fan when they feel too hot,
  
• 28%  use a space heater
• 30% said they leave their office building to warm up or cool down by taking a walk.
• 41% report their discomfort to an office manager or facilities worker
• 69% try to remedy the situation by adding or removing a layer of clothing.

The findings provide further insight into employee behavior and workplace conditions.

I mentioned that even though I've been researching and writing about windows and doors, I still wasn't sure whre "fenestration" came from.  I mused in front of the wrong person!!!

Fenestration

Here's my version:  The term is derived from an 18th century contractor who wasn't very good at his job, but who livened up the workplace as  the butt of all jokes... George Fenester, the window guy, could not install a window without breaking at least one pane of glass.   On a particularly troubling day, he fell backwards and shattered an entire stack of glass panes.  His buddies kidded him by asking, "Hey George, feeling a little Fenestration today?"  It was followed by howls of laughter...they found it humorous, most likely because they were uneducated laborers who did not have access to fine comedic programming...or even to TV for that matter.

The McKinsey Research Report

Starting in 2007, the McKinsey research team worked with leading experts to develop a detailed fact base estimating costs and potentials of different options to reduce or prevent greenhouse gas emissions in the US over a 25 year period.  The team analyzed more than 250 options encompassing efficiency gains, shifts to lower-carbon energy sources and expanded carbon sinks.

Central Conclusion

The US could reduce GHG emissions in 2030 by 3 - 4.5 gigatons of CO2e using tested approaches and high-potential emerging technologies.  The cost would be less tan $50 per ton, with the average net cost to the economy being far lower if the nation can capture sizable gains from energy efficiency.  Achievement of these reductions would require strong, coordinated, economy-wide action that begins in the near future.

One complicating factor is reaching goals is that a gradual decrease in the absorption of carbon by US forests and agricultural lands will reduce achievements, and require greater GHG reductions.

Abatement Opportunities

• The largest option -- coal-fired power plants -- offers less than 11 percent of total abatement potential.  The largest sector (power generation) only accounts for approximately 1/3 of the total potential.
• Almost 40% of abatement could be achieved with options that would generate positive economic returns over their lifecycle. 
• Abatement potentials, costs and mix vary by geographic region. 

Five Sectors offer Clusters of Abatement Potential

1. Improve energy efficiency in buildings and appliances  (710-870 megatons)
This cluster of options includes:  Lighting rtrofits, Improved heating, ventialation, air conditioning systems, Building envelopes, and building control systems; Higher performance for consumer and office electronics and appliances...and other options.

2.  Imcrease fuel efficiency in vehicles and reduce carbon intensity of transportation fuels (340-660 megatons)
Most of the benefit would come from fuel economy packages such as light weighting, aerodynamics, turbocharging, drive-train efficiency, reduction in rolling resistance, and increased use of diesel for light-duty vehicles.  Plug-in hybrid vehicels offer longer-term potential if vehicle cost/performance improves and the nation moves to a lower-carbon electricity supply.

3.  Industrial Sector pursues various options cross energy-intensive operations (620-770 megatons)
A multitude of fragmented opportunities exist within specific industries:  Equipment upgrades, process changes  -- and across setors:  Motor efficiency, combined heat and power applications. 

4.  Expand and enhance carbon sinks (440-590 megatons)
Increasing forest stocks and improving soil mnagement practices are relatively low-cost options.

5.  Reduce carbon intensity of electric power production (800-1370 megatons)
Shift toward renewable energy sources primarily wind and solar, additional nuclear capacity, mproved efficiency of power plants and eventual use of carbon capture and storage (CCS) technologies on coal-fired electricity generation. 

"The theme of greater energy productivity pervades these clusters." 

Improving energy efficiency in buildings and appliances and industrial sectors, for example, could offset some 85% of the projected incremental demand for electricity in 2030, largely negating the need for the incremental coal-fired power plants assumed in the government reference case.

Improved vehicle efficiency could roughly offset the added mobility-related emissions of a growing population, while providing net economic gains.

The Community Regeneration, Sustainability and Innovation Act of 2009 (CRSI) has been designed to create a new program within the U.S. Department of Housing and Community Development (HUD) targeted toward cities and metropolitan areas experiencing large-scale property vacancy, abandonment and population losses.

 

The act's supporters say it will provide assistance to communities to start or expand land banks that establish public control over vacant and abandoned property so that property can be redeveloped or otherwise used in ways to "benefit the public."

 

A summary of the CRSI act, prepared by its authors, says, "The Community Regeneration Act would encourage innovation, experimentation, and environmentally sustainable practices through collaborative efforts to reuse land bank properties in ways that will provide long-term benefits to the public, whether it is through the creation of green infrastructure, economic development, or other strategies. Implementation of such strategies would create new and sustainable employment opportunities for residents. The Community Regeneration Act would also strongly encourage multi-jurisdictional or regional approaches to addressing the problem of vacant and abandoned property."

 

Brad Guy, a deconstruction consultant and former president of the Building Materials Reuse Association, was asked to provide input for the language of the bill as it relates to deconstruction and the re-use and recycling of materials.

Allowable Uses for Funds

Funding is for it to go toward the "establishment of recovered building materials reuse and recycling infrastructure, facilities, and technical support."

 

CRSI as currently proposed, is for the "establishment of local government purchasing requirements for deconstruction to make use of existing building materials stock in new and rehabilitation construction."

 

In areas where land banking has created a portfolio of vacant properties, the CRSI also would allow both the "deconstruction and demolition of vacant and abandoned properties" and the "demolition and removal of public infrastructure" to be be funded through the act.

I love light, as we all do.  But balancing cost of good lighting with quality is a design challenge.  Retrofitting lighting systems can save significantly on office or manufacturing facility energy costs.  Here are six lighting retrofits that community colleges in California have been implementing to save on their energy costs ... and their environmental impact.

New Generation 25 Watt T8 Lamps
The Philips Energy Advantage 25 watt T8 fluorescent lamps were tested at an elementary school in San Diego CA.  They showed that the 25W lamps saved as much as 7W per bulb, but some application limitations were noted, such as a warm up period was required for full lighting, they are not recommended with occupancy sensors or dimmin ballasts, and they have a higher per bulb cost than 3100 lumen T8 bulbs. 

T5 or T8 High Bay Lighting in Gyms and Open Areas
According to Bright Ideas Lighting Company, "Many people are strongly pushing 4 lamp T5 highbays to replace typical 400 watt metal halide fixtures.    While I think this is not a bad option, in many cases the high bay T8 6 lamp fixture is a better option. Despite the long life rating claims for T5s we are seeing a surprisingly high rate of failures.  We seem to be changing a lot of T5 ballasts in areas where they are less than 2 years old."
 
LED Exit Signs
There are no simpler applications of savings in 24/7 lighting products that will save you money for energy and maintenance than LED exit signs!  Illuminated exit signs are an important and legally required safety feature in your facility. In the case of an emergency such as a fire, their operation is critical in protecting the well being of your congregation's members. By design, exit signs operate 24 hours per day, and can consume large amounts of energy to operate.

Many exit signs in today's buildings use older, incandescent and fluorescent/compact fluorescent lighting (CFL) technology. To make matters worse, many older exit signs require frequent maintenance due to the short life span of the lamps that light them. For example, many older exit signs consume over 350 kilowatt-hours (kWh) and cost $28 each annually to operate.

Recent advances in LED lighting technology have allowed exit sign manufacturers to develop signs that harness the advantages of this technology at competitive costs. In addition, exit signs are easy to install, if you can install a light switch or electrical receptacle you can install an exit sign. ENERGY STAR labeled LED exit signs use approximately 44 kWh of
electricity annually to operate. Low energy use not only means less pollution but also lower electricity bills as a LED exit sign usually costs less than $4 annually to operate. labeled LED exit signs use approximately 44 kWh of electricity annually to operate.  

Bi-level Stairwell Lighting

The Bi-Level Smart Stairwell Luminaire meets lighting and safety code requirements for occupied interior stairwells, while saving energy by sensing occupancy at every fixture and drastically reducing the lighting level during the many hours when no one is present. The fixture is practical for both new and retrofit applications, and it can also be used in other low-occupancy locations such as break rooms and hallways.

This luminaire operates at two lighting levels. It maintains a low light level when the space is unoccupied and quickly switches to full light output when occupancy is detected. These integrated controls, coupled with a high-efficiency electronic ballast, reduce system operation and maintenance costs and extend lamp life.

These bi-level lighting solutions save up to 70% energy savings over traditional products and lamps need replacing less often for additional savings in maintenance costs.

Occupancy Sensors in Classrooms, Offices, and Gyms

Occupancy sensors turn lights on when people need them in a room, and turn them off when the room is empty.  Automated sensors make up for human error or negligence in turning lights off when not needed.  Operated with infrared sensors, occupancy sensors ssave energy, are convenient, automatic lighting that can easily be retrofitted in offices, classrooms and other areas that are periodically used.

Daylighting Control
Sunshine is wonderful...in the right place at the right times.  Good controls are the design key to saving energy with daylighting "In fact, if designed correctly, daylighting control has the ability to delight occupants. By removing glare and making the amount of light flexible to meet different needs, daylight can replace a significant amount of electrical room lighting.   New retrofitting products such as solar tubes, shelves that bounce light, indirect lighting designs and blinds that direct light where you want it are just a few of the "passive" approaches to daylighting controls. 

Daylighting not only saves energy, but is being proven to improve spirits of the people in the room, raise productivity, and reduce illness and sick days.  Not bad for simple sunlight!
