Learning Outcomes

The learning outcomes listed below contribute to the Engineering Benchmarks A1,A2,A4,A5,B1,B2,B3,B4,B5,B6,B7,C1,C3 and C4 as specified in the BEng Building Services Engineering Programme Specification Document.On completion of this module the student should be able to:- Recommend treatment of a room with specific types and amounts of absorbent material to achieve a suitable reverberation time and reduction in background sound pressure level. (A4,A5,B2)- Calculate sound transmission loss through walls containing doors, windows and air gaps (A1,A2,A4,A5)- Calculate sound levels in a room resulting from noise generated in and transmitted through the air-conditioning system. (A2,A4)- Use British and International standards and laws to assess the acceptability of sound levels measured in a range of built environments. (A4)- Design cost-effective lighting installations, taking full account of electrical and heat loads. (A2,A4,A7,B2,B3,B4,B5,B7,C4) - Apply tariff schemes and evaluate the performance of distribution systems with regard to them (A6)- Describe the operation of electrical services designed to provide a safer building environment (eg safety lifts, emergency lighting, fire alarms). (A2,A7)- Design emergency lighting and fire alarm systems in full compliance with all current legal and technical requirements. (A2,A3,A4,A7,B2,B3,B4,B5,C3,C4)- Perform a fire-risk assessment exercise on a public or domestic building and suggest methods by which improvement might be achieved. (A6)- Complete a significant electrical distribution design case study using appropriate tools and and techniques. (A2,A7,B2,B3,B4,B5,B6,B7,C3,C4)

Teaching / Learning Strategy

The lecture material and material for directed study will be combined into one or more integrated word-processed documents which will include plenty of tutorial questions and worked solutions. This will free lecture periods for in-depth discussion of critical parts of the material and for tackling case studies integrating the subject areas in the module. Learning and teaching strategies will be developed and implemented, appropriate to students'needs, to enable all students to participate fully in the module.
