Reduction of energy consumption of buildings is an important step in the move towards a sustainable economy. How can buildings be made net zero energy, in different climates? This course introduces you to zero energy design. It will teach you a stepped approach to design a zero energy climate concept for existing buildings: homes, schools, offices, shops etc. It will demonstrate how an integrated approach, which takes into account both passive measures (such as thermal insulation and sun shading) and active measures (such as heat pumps and photovoltaic panels), can deliver the best results. It will do so by providing you with an overview of possible measures, and through reviewing several case studies of zero energy buildings in the Netherlands, with lessons for other climates as well. Thus, you will learn which measures are most suitable for individual buildings under local climate conditions. This course is for anyone interested in making buildings more energy efficient, who already possess asic technical knowledge.

The vast majority of our grid-scale storage of electricity uses this clever method. Electricity faces a fundamental problem that comes with pretty much any product that’s provided on-demand: our ability to generate large amounts of it doesn’t match up that closely with when we need it. The storage of electricity for later use, especially on a large scale, is quite challenging. That’s not to say that we don’t store energy at grid scale though, and there’s one type of storage that makes up the vast majority of our current capacity.

Wind can be one of the most critical and complicated loads on civil structures. The case of the Tacoma Narrows bridge is a well-known cautionary tale that’s discussed in engineering and physics classrooms across the world. Both resonance from vortex shedding and aeroelastic flutter contributed to the failure. When you push the envelope, you have to be vigilant because things that didn’t matter before start to become important (e.g. wind loads on lighter structures). Unanticipated challenges are a cost of innovation and that’s something that we can all keep in mind.

Earthquakes have always been a terrifying phenomenon, and they’ve become more deadly as our cities have grown — with collapsing buildings posing one of the largest risks. But why do buildings collapse in an earthquake? And how can it be prevented? Vicki V. May explains the physics of why it is not the sturdiest buildings, but the smartest, that will remain standing.

This video shows how simple reinforcement is used to prevent collapse of rock tunnels. Tunnels play an important role in our constructed environment as passageways for mines, conveyance for utilities, and routes for transportation. Rock bolts are a type of reinforcement for stabilizing rock excavations, usually made from steel bars or bolts. This simple construction method dramatically reduces the cost of making tunnels through rock safe from collapse.

This course looks at how increasing greenhouse gases are warming the climate and what it means to decarbonise - reduce the greenhouse gas intensity of - the power sector. It will also provide a range of arguments in favour of decarbonisation, including consideration of ease of access to a secure and affordable energy supply and improvements to health and the environment. This course gathers together information about these different motivating factors for building a lower carbon power sector in one place, and includes a careful consideration of the importance of the political context. This course will challenge you to critically analyse your own political context. We would welcome advisors to senior decision makers in government, civil society activists and others interested in understanding and promoting renewable electricity to take this course. This course will help you develop a better understanding of the different dimensions of a move towards a cleaner power sector and develop more nuanced and detailed arguments.

This video shows more destructive testing to answer your questions about concrete. Concrete's greatest weakness is its tensile strength, which can be less than 10% of its compressive strength. So, we often reinforce it to create a composite material strong against all types of stress. This video briefly touches on conventional rebar and prestressed/post-tensioned reinforcement.

This video explains why ridges move, and other musings on thermal movement of large civil works. Most people have a certain intuition about thermal expansion, but you may not have considered how engineers design to accommodate it on large civil structures. The video gives a quick overview on this important consideration that engineers must account for when designing infrastructure like pipelines, bridges, and even sidewalks.
