1.0 Introduction Buildings as Sustainable Energy Systems

Image
In this first video of the course, prof. dr. Laure Itard introduces you to the Buildings as Sustainable Energy Systems MOOC. She will explain the structure of the course, the different topics and how the different weeks are connected to each other. Hello, my name is Laure Itard and together with my team we have set up this professional certificate program ‘Buildings as Sustainable Energy Systems’.  Welcome! All together we have a tremendous task to achieve to make the world’s building stock sustainable. With this program you will acquire the knowledge needed to understand the thermal processes in buildings and the interactions between building design, occupants and energy systems.  This way you will be able to make better designs of building components or entire buildings, their HVAC and their energy systems, by the way HVAC stands for heating, ventilating and air conditioning. You will also be able to understand policies in this area and maybe to shape the development of futu...

What you'll learn

All about the energy chain approach, which is a powerful tool to achieve low energy and low carbon buildings. To estimate the most important heat losses and gains in a building. How to achieve thermal balance of the building and determine its space heating and cooling needs. How to estimate the heating energy demand for hot tap water and the electricity needs for appliances and lighting. How to achieve a low energy demand by optimizing window size, insulation, orientation and ventilation while taking into account building occupancy.

About this course

Building design strongly influences the quantity of heating, cooling and electricity needed during building operation. Therefore, a correct thermal design is essential to achieve low energy and low carbon buildings, with good indoor air quality. This course will enable you to understand the basic principles of the energy chain: demand, supply and distribution; and how they relate to design principles for sustainable and energy-efficient buildings. Second, you will discover what type of heat losses and gains take place in buildings’ operations. You will learn how to estimate these flows using simple meteorological data and construction properties. You will acquire knowledge on how to estimate heat transfer through construction, ventilation, solar radiation or caused by internal sources or heat storage in the construction. Third, you will learn to make estimates of buildings’ energy needs on an hourly basis by using simple static energy balances: how much energy comes in and out and whic...
