Introduction
Buildings use about 40 per cent of global energy, 25 per cent of global water and 40 per cent of global resources in their construction and operation. Governments around the world have recognised the importance of tackling energy consumption in the built environment and have instituted legislation to address these issues. These resulting measures have often been supported by financial incentives to implement alternative energy systems and processes. They are also governed by rigorous targets and deadlines. Technologies that harness solar, wind and hydro energy are now established systems for generating power and heat. Along with other innovations, such as heat pumps and biofuel, these sustainable energy systems are often incorporated into the design of new construction projects.
The aim of this unit is to develop students’ knowledge of current and future energy technologies and to be able to apply that knowledge to the analysis and assessment of their effectiveness. Students will also apply their knowledge and research to a design activity.
On successful completion of this unit, students will be able to research and design alternative energy systems and assess new technologies available to the construction industry.
Learning Outcomes
By the end of this unit, students will be able to:
LO1 Examine the different contexts that inform discussions on environmental sustainability
LO2 Discuss types of alternative energy systems and how they support sustainability
LO3 Explain the factors that inform the selection of a renewable energy system in relation to a specific installation
LO4 Present a strategy for a cost- effective upgrade to an existing building, utilising an appropriate form of alternative energy.
