I love the novel ways that items destined for the scrap heap become something new and different. This recently completed Jumbo Hostel (located in Stolkholm Arlanda, Sweden) is one of the most novel examples of green building that I have come across. I consider this green building because the major structure of the hostel was once a 747 Jumbo Jet. It is made of durable materials, had reached the end of its intended life, and now as been recycled to house travelers at the airport. A good green building should also be of a visual design that is appropriate for its location. Given that this hostel is located right at the airport, the aerodynamic shape is perfect for the setting. 

There are 25 rooms in all with a total of 85 beds. Even the cockpit was turned into a double-bed suite. The renovation of the aircraft had to meet the same building codes of any structure. The left wing can be walked on and is an observation deck for observing other aircraft at the airport.

Photovoltaic panels generate clean power by converting sunlight into electricity. This article will talk about the actual—verses the rated—power output of photovoltaic panels. Do not assume that a PV panel rated at 170 watts of power will actually give you that amount. It will probably be closer to 150 watts per panel. Because of the difference, care must be used when sizing the system for your electrical needs. Otherwise, you may find that you are generating less power than you need.

Designing a photovoltaic system for your green home starts with using energy efficient appliances and lighting inside the house. My rule of thumb is that it is cheaper to buy a new EnergyStar-rated refrigerator for under $1,000 than to spend an extra $2,000 on photovoltaic (PV) panels to power an old, inefficient refrigerator. The same goes for other appliances—particularly those that get a lot of daily use such as televisions.

The photovoltaic system for my small straw bale home (featured on the BuildingWithAwareness.com website and DVD video) cost around $12,000 in equipment. Without carefully choosing the most efficient appliances and  lighting, the cost would have been dramatically higher.  (more…)
