Museums have a hard line to walk, exhibiting items for public education and enjoyment while protecting those same collections from damage. Today’s museum also carry the additional weight of safeguarding the future of the environment – as well as their financial future – against the dangers of unnecessary energy consumption. What advancements have been made in preservation lighting technology to help accomplish these goals?

Light, including all three types: ultraviolet (UV), infrared, and visible light, causes permanent and irreversible damage to museum pieces. Cumulative and dependent on the intensity and duration of exposure, light affects chemical composition, physical structure, and, the appearance of a collection. There is no conservation treatment that can repair it. Light damage is forever.

Only complete darkness ensures conservation, since exposure to light in any form naturally breaks down items. However, keeping pieces locked away in the dark defeats the mission of the museum – sharing those works with the public. It is thus a museum’s dilemma to find a suitable solution that balances the best of both worlds, in addition to considering energy costs and the environmental impact of its lighting selection.  

In your search for preservation lighting, you will find that a great deal of lighting solutions involve UV (ultraviolet light), the most energetic and destructive form of light. These include natural light, fluorescents, HID, and tungsten halogen lighting. Fortunately, the effects of UV can be controlled with simple filters, offering a greater variety of lighting options. UV filters are hard plastic tubes or soft sleeves wrapped around bulbs/light sources, which filter and block up to 98 percent of UV light, preventing its damaging effects. NOTE: UV filters lose efficiency over time and must be replaced every eight-10 years.

Specific, detailed recommendations for preservation lighting levels based on your collection type can be found from various sources, including the Library of Congress, National Park Service, UNESCO, and more.

Los Angeles is undertaking a quiet revolution, a switchover to electric cars. This is a revolution that promises bluer skies and greater freedom from foreign oil. At this writing, the Middle East is involved with its own, noisier revolutions, and the stock market is tumbling thanks to perennial shakes over skyrocketing oil prices. Everybody who wants to be independent of foreign oil right now, raise your hands!

Getting back to the other revolution, the quiet one, going on in Los Angeles… car makers and dealers, drivers, and electrical contractors are all involved in a switchover to electric vehicles (EVs). The government is backing it with tax credits and rebates. More on that in later posts.

In December 2010, Nissan started selling an electric car in L.A., the Nissan Leaf. Early this year, G.M. will start selling the electric Chevy Volt. This revolution isn’t confined to L.A. – all along the West Coast and some of the East Coast, deliveries of EVs to new owners are starting. But L.A. is out ahead of a lot of the rest of the country. The Leaf and Volt won’t go on sale, for example, in South Carolina until next December. Pike Research, a transportation analysis firm, has projected that only New York City will beat us out in electric vehicle sales. Pike Research projects 96,000 EVs will be sold in L.A. by 2017. Of course, EV sales could move faster if the price of gas shoots past projected levels.

Both the Nissan Leaf and Chevy Volt will be priced for middle income families. As electrical contractors in Los Angeles, we’ve already started installing chargers, including in home garages, apartment buildings, and commercial venues.

The Leaf is all-electric with an average range of 100 miles before its battery needs to be recharged. The Volt is a hybrid. With a fully charged battery, it can drive about 35 miles and then, it starts burning gas. Drivers can recharge their Leaf or Volt batteries by pulling out their special cord called a “Level 1 Charger” and plugging it into an outlet that carries regular house current.

The advantage of Level 1 charging is that it’s simple and inexpensive to set up. Hire an electrician to install a circuit in your garage or carport. It will need to be a dedicated circuit, meaning that no other appliances, like a washer, for example, will use it. The outlet will need to be the safety version usual in garages and outdoors (a GFI outlet). Also, your electrician will need to check whether your electrical panel should be upgraded in size to handle the increased power demand. Once the outlet is installed, the EV driver pulls out the Level 1 charging cord that comes with the car, starts charging, and lets the car sit … for a long time.

Level 1 charging is… well, slow. A Chevy Volt battery takes 10 hours from empty to full; a Nissan Leaf takes 20 hours. But help is on the way – Level 2 charging. More on that in my next post or click here for our article which talks about Level 2 Charging.

There was a time not too long ago when gas and electricity costs weren’t really a topic of concern at all. Keeping in view expenses such as mortgage payments, insurance etc, energy bills faded in comparison. However, that is no longer the case today. Energy costs have become a major concern for property owners and the need of the hour is for energy – efficient solutions to be incorporated into the home.

And there is no dearth of these types of solutions. Ranging from LED bulbs, use of solar energy, smart lighting, optimum insulation, use of energy-efficient building materials, switching from standard ovens to convection ovens, people are trying everything in the book to coax their energy bills to drop a little bit. While all these measures are definitely helpful in bringing down energy consumption, there is one more thing consumers can do to keep a handle on their energy bills- use smart lighting schedules!

Energy providers in Australia charge consumers a variety of rates; this is based on the type of meter in the house and the manner in which energy is used in peak & off-peak periods. There is no standard rule here as different retailers maintain different energy rates. The one way to get a much reduced rate is to opt for a long-term energy contract. It’s important to shop around a bit as the difference in rates between providers can be significant.

Off peak times are those when businesses and homes typically use less electricity. The off peak time is dependent on your meter type and location; however, these are typically on weekends and/or at night. When consumers use electricity in busy peak times, it burdens the electricity networks in the country. It’s also why energy usage in the off-peak hours is charged at much lower rates. This is the way consumers are encouraged to use power outside busy hours.

There is another definition of off-peak rates. This can refer to the electricity used by a particular appliance on a dedicated circuit. For instance the electric hot water system in your house could be on a separate circuit and will be billed separately, on the off peak rates your service provider is offering. It’s possible to leverage this off-peak rate to reduce energy costs in your home. You can use interval metering or off-peak hot water to benefit from these lower rates at set times of the day and the weekends.

If you are considering using smart scheduling, it’s important that you contact your energy provider and find out if it’s something they accommodate and what you are required to do.
