article With an increasing need for green buildings, architects and designers are working to create sustainable buildings using a combination of renewable energy, building materials, and a roof.
Here are a few tips and tricks to get your green building design on track.
Selecting a roof is a matter of personal preference, says Richard Haggerty, an associate professor of architecture at the University of Missouri-Kansas City.
“Most architects have an aesthetic preference.
But, if you’re a designer who doesn’t know what you want, then you have to pick a roof that you can live with,” he says.
The more vertical you place your roof, the more energy it can store.
According to Haggertys study of the roof of an apartment building in Seattle, a horizontal roof with an additional 30 percent of its area as roof space actually saved the energy of the building.
A roof should be flexible and be capable of being raised or lowered, so you can move your floor plan or change the size of your windows.
The roof should include a minimum number of columns, so that it’s not too tall and the columns don’t pinch too hard.
Haggerts study found that roofs with minimum columns actually generated more energy.
To save energy, architects should look for materials that are both durable and cost-effective.
In this article, Haggertz points to bamboo, which is lightweight, lightweight, durable and flexible.
The materials he cites include bamboo, pine, fir and cedar.
The type of material you use can also help you create a roof with fewer materials.
Haggtys research found that a combination in materials and size saved the most energy from a roof built with bamboo, and in particular bamboo made from a tree with an average canopy diameter of 14 inches.
Building with materials that can be reused is the key to creating a roof of sustainable design.
“We are constantly looking for ways to reuse materials.
For example, if we are building a roof for a home, we can reuse the timber that was used to build the roof, and then we can use a new material for the walls or the foundation, or even the roof,” Haggerttys says.
When it comes to roofing, a vertical roof is the most efficient.
In his research, Haggts found that an overall energy savings of 7 percent per year was achieved by using a vertical structure with a minimum of 6.5 feet (1.3 meters) of vertical support, a height of 20 feet (6.6 meters) or a width of 10 feet (3.5 meters).
Hagerts study also found that horizontal roofing systems using a variety of materials saved energy when compared to a vertical system.
For instance, when Hagger’s study compared the energy savings for an 8-foot-by-4-foot (1-meter-by, 2.5-meter) roof with a 3-foot by 4-foot roof, it came out to a savings of just 1.2 percent.
In Hagger, Hagan and Haggerzys study, the most common material used to construct a roof was pine.
“When I designed the study, I looked at different materials that were in use in the industry,” Hagan says.
“I tried to find materials that would be cost effective and durable and yet be lightweight.
For the roof that I built, I used pine.
It’s not just the material.
I looked for materials like the fibers that make up the bark of the trees, the fibers, the fibres that make the bark, the fiber structure that makes the wood, and so on.”

Hagan points to a combination, like birch, which provides insulation in addition to a roof, while the researchers found that wood and cork were the two most cost-efficient materials.
They also found a high level of resilience in the materials used.
“The more durable the material, the better,” Hagry says.
For this reason, HAGY says the next time you are building your own home, make sure you select a roofing material that’s made of durable and energy-efficient timber.
The best choice, HIGHER says, is the same kind of wood that you would find in your local lumber yard.
“You have to make sure that the trees you use are a good quality,” he explains.
The researchers recommend using cedar, fir or cedar-like timbers.
“Those are the best choices for these types of buildings because they are strong and they
