| Assessment task details and instructions This assessment has been designed to introduce some realistic practical activities into your study of Building Services. It is hoped that by examining various aspects and issues raised by seeking to incorporate building engineering systems into a structure you will gain an increased familiarity with the role of the Building Services Engineer and the day-to-day problems he/she may encounter.
By focusing on a pseudo client brief this assignment will focus on the following major aspects of a Services project: · Heating Systems; · Ventilation Systems; · Domestic Hot Water Services; · Environmental Control Systems.
Over the course of the last few years the university has experienced a significant increase in the number of students wishing to study health subjects. The development in these courses initially saw the development of the Mary Seacole building which provided the required teaching and practice space to support learning activities alongside some limited medical research. Senior management have recently acknowledged that the development of a dedicated medical research facility is required in order to further develop this area of the business and seek to become a centre of excellence in this subject.
Young and Simpson have been working with the university to develop initial design ideas for the building and the point has been reached where they can be used to begin to examine the possible building services systems that might be included in the completed design. The outline plan for this building along with other useful information is included in appendix 2 of this brief.
You work for the building engineering services consultant George Smith and Co. who have been appointed to carry out initial services designs for the project. As part of the services development team you have been charged with producing a professional report that must be formatted to include. · A front cover in the form of a title page. · A contents page listing the title and page number of all sections, subsections, appendices and reference listings. · Body text with use made of appendices if appropriate. · References deployed appropriately throughout the document in the Harvard format. · Appropriately numbered sections and subsections. · A choice of format and font that is accessible to the reader.
The final report is to address the following activities.
Activities 1. Provide an introduction that clearly states what may be considered the major building engineering service systems that might be included within the medical research centre. Include an explanation of what service systems seek to achieve within a building. 2. Heating Systems Carry out the following. · Explain what type of heating system might be appropriate for this building and justify your thoughts. The explanation is to consider a type of boiler, the distribution system and two possible types of heat emitter. · Calculate the heating load for the five rooms listed below and located on the left of the drawing in appendix 2. i. 3 no. Research and Audit rooms. ii. 2 no. Catering rooms. 3. Ventilation Systems Explain what is meant by the following: · Mechanical air handling. · Natural ventilation. Select and justify one of these systems that might be appropriate for the medical research centre. 4. Domestic Hot Water System Explain what is meant by centralised and de-centralised domestic hot water systems and subsequently select an appropriate method of providing domestic hot water throughout the building. Clearly justify why your choice is appropriate. 5. Environmental Control Systems Provide a description of how heating systems can be controlled to provide comfortable internal conditions for occupants. 6. Installation practice Explain the difficulties and limitations that the building structure might place on the distribution of heating and mechanical ventilation services around a building. Your answers are to be supported by visual examples of solutions used to install both types of system.
Guidance regarding how your submission will be assessed is given in the Assessment Criteria section below. This should be read in conjunction with the Assessment Rubric included as Appendix 1.

| Module Aims 1. To develop knowledge and understanding of the interactions between a building and its internal and external environments and hence develop an awareness of the physical and personal requirements for thermal and environmental comfort leading to a healthy working environment 2. To provide students with a fundamental understanding of the principles involved in building heat transfer, occupant thermal comfort, illumination and acoustics. 3. To explore the need for Mechanical and Electrical Engineering Services within the building envelope and develop an understanding of typical Building Services systems technology. 4. To develop knowledge and understanding of the wide spectrum of H.V.A.C. Engineering Services available for installation in today’s buildings and their impact on sustainability, health and safety. 5. To develop an ability to appraise and critically analyse the choices available to the engineer when selecting systems to meet a services specification. | |||||||||||||||||||||||||||||||||||||||||||||||||||||
