The story of architecture is the story of humanity. The buildings we live in, from the humblest pre-historic huts to today's skyscrapers, reveal our priorities and ambitions, our family structures and power structures. And to an extent that hasn't been explored until now, architecture has been shaped in every era by our access to energy, from fire to farming to fossil fuels.

In this ground-breaking history of world architecture, Barnabas Calder takes us on a dazzling tour of some of the most astonishing buildings of the past fifteen thousand years, from Uruk, via Ancient Rome and Victorian Liverpool, to China's booming megacities. He reveals how every building - from the Parthenon to the Great Mosque of Damascus to a typical Georgian house - was influenced by the energy available to its architects, and why this matters.

Today architecture consumes so much energy that 40% of the world's greenhouse gas emissions come from the construction and running of buildings. If we are to avoid catastrophic climate change then now, more than ever, we need beautiful but also intelligent buildings, and to retrofit - not demolish - those that remain. Both a celebration of human ingenuity and a passionate call for greater sustainability, this is a history of architecture for our times.
Reducing energy use is the single biggest challenge facing architecture today.

From the humblest prehistoric hut to the imposing monuments of Rome or Egypt to super-connected modern airports, buildings in every era and place have been shaped by the energy available for their construction and running.

This original and compelling survey tells the story of our buildings from our hunter-gatherer origins to the age of fossil-fuel dependence, and shows how architecture has been influenced by designers, builders and societies adapting to changing energy contexts.

Architecture is a fascinating celebration of human ingenuity and creativity, and a timely reminder of the scale of the task ahead in our search for truly sustainable architecture.
