Save energy and Money by weather stripping your house

I originally wrote this for Tashman Home Center

Weather stripping your home can save you money for several different reasons. While Southern California may not have harsh winters, it does have heat and our famous Santa Ana Winds and with climate change increasing the frequency and severity of both, weather stripping your home might be worth considering. Whether your cooling or heating a home or want to cut down on the amount of dust that slips in around your windows and doors, doing an energy audit will let you know if makes sense to spend the money weatherizing your home. Here is a list of professionals that provide Energy Audits,

If you’d prefer to check things our yourself, here are several things you can do:

Windows

Use a stick of incense or a candle during a windy day to go around the windows and see where air is leaking in. During this wind test also check the windows themselves for cracks or other problems that can easily be addressed.

When dealing with sliding windows, there are a few simple things that will make a big difference with respect to unwanted air flow. Attach vinyl weather strips to the sides of the windows and foam strips on the bottom. Also put a V-Channel weatherstrip where the window goes into the frame to create a complete seal. Another option if you don’t plan on opening the windows for a while is to fill the cracks with caulking. The best product to use for this purpose is called seal and peel caulk. It is made to be easy to remove so you can quickly open up your house when spring comes.

Doors

When you close your front door, ideally it will make a strong seal. Use open cell foam weatherstripping for the sides of the door and a sweep for the bottom to keep out drafts.

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.

Solar Powered Air Conditioners are Becoming More Elaborate

Air conditioners can consume an incredible amount of power. Between the electricity the compressor utilizes and the torque of the motor in order to spin the fan, your electric bill can skyrocket over the summer. In order to reduce the cost of this unit, some have installed solar panels onto the roof specific to the sole use of the AC device. However, innovative designs have made development of these units far more elaborate than in previous years.

Mobile Cooling – Many people like the idea of being able to maneuver a cooling device set on wheels in order to maximize the effect in any given room. Developers have created a small unit that can be rolled across the floor while being connected to a solar panel. With some of these smaller units, you can essentially place the panel in the window as long as the sun’s light can reach. These can be incredibly useful if you need a solution that can travel with you from one room to the next.

Ductless Heat Pump Units – Operating at 18,000 BTU, some of these ductless heat pump units can reduce power consumption by nearly 97-percent. Solar panels as well as the mini-split design allows for installation nearly anywhere. Once the sun light is minimal, the heat pump automatically switches to an energy efficient device taking its power from the grid. Although some of these are not 100-percent dependent on solar power or battery backups, the units can still reduce your day-time spending per kilowatt hour.

Hybrid Heating and AC – Some units have been developed to act as both air conditioning and as heaters in order to keep rooms comfortable year round. Although this isn’t necessarily a new idea, the addition of solar power to operate these units decreases your spending regardless of season changes. Some of these miniature HVAC systems can range from small 5,000 BTU devices to more powerful machines producing more than 40,000 BTUs. Depending on your own room requirements, hybrid systems can keep you cool in the summer and warm in the winter while using less power from the grid.

Central Air – Central air is an efficient method of keeping the home cool in the summer. Solar power adaptations have been created that can operate in a hybrid unit offering cool air as well as heat. Using energy efficient technology and including its own dedicated solar panel, these units are far less costly to maintain than the gird-dedicated counterparts of the past.

Do it Yourself Projects – If you can’t find something that fits your budget or your specific needs, you can always build one yourself. There are many different ways that these units can be assembled – most of them using upcycled parts from various machines. Your own imagination and skills with a soldering iron will play a role in how elaborate you make your own solar AC unit. You may even design something that is marketable to make a few extra dollars.

With each passing year, an innovative method is developed to include solar energy. Air conditioners, outdoor camping showers, ovens, toys, boat engines and more have been adapted to utilize one of the most abundant sources of power humankind has discovered. What was once an expensive addition for the upper class has decreased in cost to the point where nearly everyone can benefit in one form or another from solar energy. Imagine what will be developed tomorrow.

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.

Photovoltaic PV Solar Panels on the rise

Lowered costs and increasing efficiency have helped the steady increase in the use of Solar PV panels.
There have been some incredible advances in the methods used to capture solar energy.  Solar paint and thin plastic cells are some of the new technologies but PV panels are still the most efficient way to capture energy from the sun.

The modular nature of solar cells are also being used in more creative and aesthetically pleasing ways. Each cell must have a separate connection because stringing them together has the same effect as Christmas lighting, if one goes out, there all do. Being modular, however, increases the versatility of the panel placement.

Increased efficiency has also made the technology workable in areas that don’t receive a huge amount of direct sunlight. Solar power is a small thing that most landowners can take advantage of to reduce costs and stabilize energy bills.

Cloud computing and the wasteful excesses of data centres

Cloud computing and the wasteful excesses of data centres

 

With the rapid increase in the use of cloud services and the number of cloud service options available, more data centres have popped up all over the globe, bringing with them a higher demand for electricity. Recent reports by the Energy Conservation Bureau suggest that data centres now consume 3% of all electricity generated in the United States. A September New York Times article, “Power, Pollution and the Internet”, reports that data centres waste large amounts of energy, with only 6 – 12% of energy used by data centres going towards computing.

Data centres often consist of rows of servers, computers whose primary purposes are to process data. The heat generated by these servers can melt crucial computer components, risking data loss. As data centres have grown many now spread rows of servers over hundreds of thousands of square feet and utilize industrial cooling systems to combat overheating. Tens of thousands of data centres now exist to support the heavy demands of internet use, with many of the largest internet companies running servers at full capacity regardless of demand, resulting in the excessive wasting of energy.

There are ways to build more energy-efficient data centres. Providers can consider re-evaluating their redundancy, utilizing storage virtualization, consolidating their servers, and upgrading to energy efficient technology. Some data centres utilize their environment to cool their systems, such as a local waterfall or cold Arctic air. If clients outsource data centre management to high quality facilities that follow these practices, they can avoid forming their own poor management habits. Outsourcing can also save clients from having to upscale and downscale their own equipment to match the changing demands on their business.

Though outsourcing offers advantages, if large data centres are not optimally managed, these industry practices only contribute to more energy consumption. A large data centre is not inherently more energy efficient than a small one, and the spreading of load does not guarantee a reduced need for capacity. It stands to reason the cloud service providers need more spare capacity available to serve their clients than if clients operated their own facilities. Some argue that cloud services help to improve the situation, leading to a consolidation and centralization of computing among large, well-operated data centres. This is not necessarily the case.

Powering the internet is a very environmentally unfriendly prospect. Cloud computing presents a path towards improving the situation, but it is not a solution in and of itself.
