Shaan Hurley, Autodesk blogger extraordinaire, has
been pondering the energy use of buildings and the possible impact
on the future of humanity. Philosophical stuff. How can sustainable
building design contribute towards the solution?
"As the world struggles to find ways to deal with its energy
demands, it's also becoming increasingly urban. Which is only a
problem when you consider there will be more than 7 billion
inhabitants on Earth by the end of this year, and somewhere near 9
billion around 2050.
"The fact remains that energy use is often the largest source of a
building's environmental impact. Buildings account for more than
40% of worldwide energy use - far more than cars and aeroplanes
combined. As cities continue to grow with the influx of new people
seeking employment and opportunity, the need for sustainable
building design is more relevant than ever, especially in the
developing countries where urban migrations are occurring on an
even more rapid scale.
"To improve a building's energy efficiency, you need to understand
its energy loads. Energy loads help describe the flow of energy on
the site and in the building. By understanding a building's thermal
loads and its intended use, you can more effectively use the energy
in natural systems to passively heat, cool and ventilate your
building and design efficient HVAC systems.
"Going forward, reducing energy use in buildings will be one of
the most important challenges to reducing our overall environmental
impact. Understanding the flow of energy on the site and in the
building will be essential in capturing energy in natural systems
to passively heat, cool and ventilate your building and design more
efficient HVAC systems."
To expand on the issue, Autodesk has produced a
sustainability
workshop video looking at how you could design net zero energy
buildings. Shaan's original post is part of his
Between the
Lines blog, which is hosted on the Autodesk community (where
you can also find a dedicated
sustainability
blog).
Sustainability is a big part of the BIM ethos: through
closer collaboration, a building's energy load can be reduced
throughout the construction and lifespan of the building. To learn
