Energy Efficient Windows

This post was written by me but originally appeared at http://blog.tashmans.com/

The first window was made about 3.3 million years ago and was a hole in the wall of whatever was being used for shelter at the time. The purpose was to better see enemies and wild animals approaching as well as to enjoy a cool breeze on a hot summer night.

The Romans were the first known to use glass for windows, a technology likely first produced in Roman Egypt—In Alexandria ca. 100 AD. The technology has advanced significantly over the years although some people still use Jalousie windows which are only slightly better than a hole in the wall.

Untitled-e1430525842626Before deciding on new windows it is important to know a little bit about how the sun’s radiation works. The sun emits a lot of radiation but for the purposes of window efficiency, we can focus of visible light and radiant energy (heat). The goal, in both hot and cold climes, is to allow as much visible light through while minimizing the transference of radiant energy. There are three main ways to treat glass to make it energy efficient. These are insulated glass, low e glass, and reflective coated glass.

Insulated glass windows usually consist of two or three panes of glass separated by an inert nonconductive gas like Argon. The spacers often have a desiccant, which reduces the possibility of moisture entry.

Low emissivity glass has been coated with a microscopic metallic oxide that reflects infrared light (radiant energy) and allows visible light through. Low E coatings come in different varieties which can be customized to fit a specific location, cold and dark vs hot and light.

Reflective coatings are usually used in hot areas with windows getting direct sunlight. For example the front of our hardware store has very large south facing windows so we put a reflective coating on them so we wouldn’t have to use exorbitant amounts of air conditioning. Some of the more severe reflecting coatings will turn glass into a one way mirror.

The type of frame for a window is also important for durability and energy efficiency. Aluminum windows are durable and cheap but have a high heat conductivity which is bad for energy efficiency. Wood window frames look nice and have good insulating properties but require more maintenance because wood tends to warp with heat and moisture. Fiberglass frames provide good insulation and generally look better than aluminum. Fiberglass is also very strong and can accommodate a larger piece of glass. Vinyl frames are the most energy efficient, require no maintenance and can be custom treated for any environment.

Our atmosphere and magnetic field protects us from most of the Sun’s harmful radiation and we as technologically advanced animals can further protect ourselves from other inconveniences like heat and high electric bills.

The probability of earthquakes has changed following new study

earthquake 2

A new report by the U.S. Geological survey has introduced a new earthquake forecast model that changes the forecasts for magnitude, location, and likelihood as compared to the 2007 forecast model. The most significant change is the likelihood of medium (6.7-8) quakes has decreased while the likelihood of large (8+) quakes has increased. Looking at the entirety of California, the chance of a medium earthquake has gone from one every 4.8 years to one every 6.3 years while the chance of large earthquakes has gone from one every 617 years to one every 494 years. 

The evolution of the California earthquake forecast model has happened as we learn more and more about the complex fault system under our feet. 

As we can see the number of faults has increased twenty fold in the last 17 years. In the 1988 forecast, only 16 faults were considered while in 2015 350 faults were considered to create the model. Much of these recent fault finding efforts (pun certainly intended) were driven by the fact that the 1994 Northridge earthquake occurred on a previously unknown fault. There are two other important things that contributed to this revised forecast, the use of space based geology and the observation that earthquakes jump from fault to fault instead of being constrained to the fault that spawned them. Instead of several major fault-lines, the picture that emerges is of a vast interconnected fault system. 

While the implications for building codes depends largely on where exactly structures are located, there are some important general conclusions we can draw. Tall buildings and bridges are more at risk than previously thought whereas small single family houses are less likely to experience catastrophic damage. Also the popular assumption that small quakes release pressure and make large ones less likely has been revisited to take into account the connected multi-fault system. 

How to Prepare

  • Identify safe and dangerous spots in each room. Get under sturdy desks and tables, stay away from windows, fireplaces, and hanging objects.
  • Conduct Practice drills.
  • Decide where and how to reunite with loved ones if separated during an earthquake.
  • Learn how to shut off the water, gas, and electricity.
  • Get a first aid kit and learn CPR and basic first aid.

During the Earthquake

  • If outdoors, find an open area away from walls, buildings, power lines, and trees.
  • If driving, pull over to the side of the road and stop, avoid areas around power lines and stay in the car until the shaking has stopped.
  • If in a crowded public place, do not rush for the doors. Remain calm and cover your head and neck with arms.

After the Earthquake

  • Do not attempt to use the phone unless there is an urgent life threatening emergency.
  • Check for gas and water leaks as well as damaged electrical wiring. Call utility companies if necessary. Do not attempt to re-light the gas pilot without a thorough inspection.
  • Stay away from downed power lines.
  • Do not use your vehicle unless absolutely necessary.
  • Be prepared for aftershocks.
  • Help others in need.

Urban Heat Islands and Paint

White reflects and black absorbs.

It’s a simple statement with massive ramifications if our society decides to use the science of color to fight global warming. For centuries cities in places like North Africa and the Mediterranean have been painting everything bright white to keep cool. White reflects the heat radiation back into space while darker colors absorb heat radiation and would therefore increase the temperature in and around the house.

Why did we abandon this simple technique that seems like a no brainer in places like Los Angeles? The answer is that it is much cheaper to use dark building materials. Asphalt and tar are two of the most ubiquitous building materials we use to construct cities and roads. The detrimental effect of building like that is referred to as the “Urban Heat Island” effect. This is why cities are generally much hotter than the surrounding countryside.

In cities with ample precipitation, the best solution involves plants on places like rooftops and vacant lots. The city of Boston buried it’s largest highway and built a giant park in it’s place. The “Big Dig” was a disaster as far as construction projects go but the original concept was great. (When I was ten years old, the Major of Boston told me the Big Dig would be done in five years…I am now thirty and they just finished.)

The problem with this approach in Los Angeles is the complete lack of rain. No one should be watering large lawns because it’s just downright irresponsible. Replacing lawns with fake grass actually contributes to the Urban Heat Island and also destroys whatever ecosystem existed there before. Residents of Los Angeles can enroll in a rebate turf removal program whereby you replace the grass with drought resistant plants and get money back from the city.

Of course if you can’t get people to vaccinate their children, the concept of deadly irresponsibility may not be salient for the residents of greater Los Angeles.

If you want to be a responsable member of society, however, paint white and tear up all that thirsty grass.

How Realistic is Ocean Front Property in Arizona?

How Realistic is Ocean Front Property in Arizona?

Due to the melting of the polar caps and the various land-based glaciers all over the world, many islands across the globe are in jeopardy of being submerged. This isn’t a “could happen” scenario as Indonesia has already lost more than 20 of its 1500 islands since 2005. It is also projected that the Maldives will be nothing more than a tropical memory by 2050. As these levels continue to rise, could there really be ocean-front property in Arizona within the next century?

Elevation Matters – Arizona’s mean altitude is 4100 feet above sea level. According to NOAA, the National Oceanic and Atmospheric Administration, the levels have been rising at 0.12 inches per year since 1992. However, it has been reported that this has been a 50-percent increase since the recorded levels of the early 1900s. If the sea levels were to continue at just over one-tenth of an inch per year, it would take 410,000 years in order to submerge Arizona. That also is based on a formula assuming that there is no further increase.

Compounded Problems – At the current rate of melting, NOAA is predicting that the water levels will actually rise by six and one-half feet by 2100. This is a calculation based on the exponential rise of the levels over a period of time. This means that the water will rise approximately 83-percent faster than the 0.12 inches per year as stated above. At that rate, Arizona could become a shore-line state in 69,700 years – plenty of time to pack your sunscreen and surfboard.

Melting Polar Caps – When you see an iceberg in the ocean, it may not look very intimidating at first. When you realize that most of these chunks of ice hide 80-percent of their mass underwater, then you can get a better idea of how large they truly are. This inspires the term, “only the tip of the iceberg.” Although this mass displaces the ocean water around it, it’s also fresh water that is contained within those behemoths. When you consider how much ice was at the North and South poles of this planet that is an incredible amount of fresh water being added to the oceans. This doesn’t include the ancient glaciers that are land-based such as those found in Peru, Alaska and Canada.

Fresh Water Induction – Added large amounts of fresh water to the ocean causes changes in how the currents react. In the movie, “The Day After Tomorrow,” this caused massive storms to populate in a matter of days. In reality, that scenario isn’t far from the truth. According to RealClimate.org, there is scientific evidence to support that the Gulf Stream currents have been reduced by 30-percent. These oceanic streams assist in the weather patterns that can be felt globally. This isn’t including the fact that fresh water puts strain on fish and plant life including decreasing overall buoyancy.

Human Made or Natural Evolution? – There is great debate about the ice-melt as being human made or just natural evolution of the planet. We have scientific evidence that can provide stability for either argument. Scientific discoveries have shown humanity that there have been as many as five ice ages in the past 2.4 billion years. Every two to three hundred million years, the conditions are ripe for the planet to essentially freeze itself. Could the melting of the global ice sheets contribute to hastening our next ultimate winter by altering the weather patterns?

Currently, Arizona is safe from becoming a port city. Although the rising sea levels could displace more than 180,000 families by the end of the century, the state’s sheer altitude provides a great deal of protection. As long as the San Andreas doesn’t snap and sink California, Arizona residents won’t have to worry about donning flood pants.

Jalousie aka louvre windows are terrible

This post was written by Alex for Tashman Home Center in Los Angeles.

louvre windows

If you live some where that is not temperate year round you may not have run into this abominable style of windows. For obvious reasons, installing these things somewhere cold is a terrible idea but installing them somewhere warm is also silly.

Invented well before the advent of air conditioning, Jalousie windows are meant to utilize natural ventilation to cool homes in hot areas like Southern California. Now that we have entered a more modern age where air conditioners are pretty standard in places like Los Angeles, Jalousie windows are a waste of money, energy , and resources.

Which brings us to the crux of the matter; the importance of good window insulation. Tashman Home Center is one of the few remaining retailers of louvre windows but we do not recommend them at all.

Instead we recommend aluminum or Vinyl windows with Low E glass for extra energy efficiency. For more on our various styles of windows, see our info page or our Catalog.

Will Water Be a Commodity More Sought After then Gold?

Hollywood has done a decent job keeping us entertained over the years. Futuristic movies have grasped out imagination with tales of how water is scarce and survival after an apocalypse is anything but ideal. However, how much content from those movies are purely imaginative considering the world wide events of today? Will the world’s supply of fresh water become as precious to us as gold and oil?

Glaciers
For the inhabitants near glacier parks, as well as providing fresh water to rivers that span hundreds of miles, the reality of no water is a fact of life. Across the globe, glaciers are melting at an incredible rate pouring greater amounts of water into the oceans. This has, in turn, increased the sea levels at a rapid pace. Within our lifetime, island cities such as the Maldives will be submerged as could be several areas of Florida and other coastal states and cities. In Peru, 1600 years’ worth of ice has melted in less than three decades. How much more will we lose as a species before preventative measures are taken?

Rain Forests
Rain forests are more important than merely providing a habitat for the creatures that live within them. Each year, rains produced within the forests have declined steadily as trees and plant life are removed to provide land for cattle and commodities. Shouldn’t the water produced by these forests be considered a greater commodity than cotton or corn?

United States
In a report completed earlier in 2013 by the Natural Resources Defense Council of Tetra Tech, more than two-thirds of the counties in the US will have reservoirs unable to sustain the population demand by 2050. Changes in the climate and irregular weather patterns will not be able to replenish reservoirs that are in use. An overwhelming amount of the population wants the government to step in and address the problem of water shortages, but very few trust that the government will do anything about the problem.

Wasted Water for Production
Did you know that it takes more than 39,000 gallons of water to produce a new car? If you consider that a single human can consume up to one gallon of water per day, this is enough water to hydrate a person for more than his or her lifetime. Industry exhausts a great deal of water between cooling, lubricating, cleaning and any other use that requires liquid. The more we consume products as a global population, the faster the water is used. The very thing that is keeping economies functional will be a major contributor to its demise if things don’t change.

Toxic Chemical Levels
Many skeptics don’t believe that humans are the cause of climate change due to higher levels of carbon dioxide that is produced through various means. While they focus the quality of air, not many look at the ground. Chemicals that we take for granted are being put into the Earth and poisoning our water supply. Whether this poisoning of the water tables is on accident or not is irrelevant. That fact is that humans are responsible for contaminating water supplies through inappropriate or negligent actions.

At the current rate of decline, it will only be a matter of a few decades before the lack of water can create situations similar to those apocalyptic movies we grew up with. Whether our governments believe in global warming or not shouldn’t be the focus of their attention. Dehydration of the population is a reality and more efforts should be involved to sustain the people of any area.

Is Humanity to Blame for the Scarcity of Water?

wasting water

 

Although skeptics don’t believe humans are the cause of global warming, or climate change, we may be responsible for the scarcity of our own water supplies. Water does more for our community than simply keep us alive. We use this liquid component in a variety of tasks from flushing waste down to sewers to cleaning toxic chemicals to the excessive use each time we frack for gas. Instead of looking for alternatives and examining how our actions affect communities and the planet, humans are more drawn to the quick and easy way to accomplish goals.

1. Deforestation – Less rainfall in particular areas of the globe can be correlated with the loss of plant life within those areas. The Amazon Rainforest, while being a prime example, isn’t the only area that has seen diminished rainfall from the lack of trees and plants. Deforestation has been greatly impacted by humans because of the need for cattle ranches, paper and other materials that could have been produced using other methods.

2. Cleaning and Waste Removal – Depending on the style of your toilet, you can use 3.5 to seven gallons of water with each flush. In a family environment, more than 100 gallons of water can be flushed down the drain each and every day. The water that fills this receptacle is the same water that we drink. While this is aside from the installation of “low-flow” toilets, showers and baths can consume a great deal of water for the family environment as well. While this depends on the shower head that is installed, a single 10-minute shower can use up 50 gallons of water. In a family environment, more than 350 gallons of water can be consumed just in the bathroom on a daily basis.

3. Fracking – Millions of gallons of water can be used in any particular “fracking” job in order to improve drilling for oil and natural gas. Although some of this waste water is recycled, a large portion of it is lost. Instead of investing in improved ways to drive our automobiles or keep the steam turbine generators spinning for power, we squander the very component life depends on even though droughts run rampant across the plains.

4. Existing Technology –
We have existing technology that can help drought-affected areas to support life, if not for the implications of a dollar amount. Large and small scale water condensers are being developed that can essentially pull the water right out of the air. Since it costs so much money to build these units, may don’t see them as a practical way to survive – as drought causes crops to suffer.

5. Lack of Effort – In areas that are affected by floods and where the humidity is so high, why can’t this extra influx of water be piped to areas that are suffering? Because it wouldn’t be cost efficient to do so. It would require effort by local and federal governments in order to provide a viable method to keep the populations alive with the one component that humans cannot survive without.

Climate change on a global scale may be caused by a natural occurrence of the planet, but humans do their part to be as detrimental to their own survival. Instead of being a species that cares for survival, we have become one that depends on the size of the pocket book. If it’s not profitable, it must not be the correct path, right?
