Module Overview:
This module develops the student's understanding of the principles of heat transfer, thermodynamics and general engineering and the application of these principles to sustainable and energy efficient design and operation of building engineering systems, plant and equipment. By the end of the module students you should be able to utilise appropriate mathematical methods to solve mechanical engineering problems.
Additional Information:
This module is designed to run in semester 1 alongside the complementary Electrical Engineering for Buildings module to provide students with the necessary grounding in the underpinning principles of mechanical engineering, heat transfer, thermodynamics and fluid mechanics, so that they may undertake the appropriate Design Project module in semester 2. On the Building Services Engineering Degree Apprenticeship programme, the knowledge learning outcomes are K1, K2, K3, K4, K5, K7, the skills learning outcomes are S1, S2, S3, S7 and S8 and the behaviours learning outcomes are B1, B6, B7.
