| Unit Learning Outcomes |
| LO1. Identify pre-design information required for a non-domestic heating system. LO2. Analyse heating loads for non-domestic buildings. |
| Submission Format |
| You are to submit an A4 word-processed document. The choice of font face, font size and line spacing are left to your discretion. However, as a professional report, clarity and readability are critically important. You are encouraged to use diagrams and graphics to help to explain the topics. Any material (images, drawings, diagrams, text) that is derived from other sources must be referenced using a standard form of citation (Harvard Referencing System). The recommended word limit is 2,500–3,500 words but you will not be penalised for exceeding the total word limit. Keep in mind that being clear and succinct are key features of professional documents. DO NOT SUBMIT YOUR WORK AS A PDF – Word documents only. Use of images/illustration: Support your work where applicable with appropriate image/diagrams. These should be clearly presented with a clear reference to source. Submission: All work will be submitted as a hard copy by hand and via electronic submission on-line – details can be found on Moodle. Any analytical work done on paper does not need to be typed, instead scan your work and combine it with the rest of your work into one document. |
| Assignment Brief and Guidance |
| Your role as a trainee building services design engineer is under review. As you are heading towards the completion of your company training scheme, your manager has decided that you have gained enough experience to complete a design for a building heating system. They have also decided that your depth of knowledge and understanding can be assessed, and additional supplementary design and comfort information should also be supplied as part of the process. You have been provided with the drawings of a building and all the other necessary information about it. You have been asked to provide information and relevant design calculations regarding a proposed non-domestic heating system which would be suitable for the building provided, including any possible sustainable options and other information that you may require. Your work should make reference to industry standard guides and legislation. Continued: |

| • Further to the assignment brief, explain the design process stages for your proposal of a non-domestic heating system. • Discuss the information that should be included in a design brief for a non-domestic heating system design. • You must produce the design data for the heating system in your proposal using a recognised method and format to include the attached drawings and data below for guidance. • Use your knowledge on the form and fabric of the building for your proposal to demonstrate how you will perform the necessary U-value calculations. • Use the U-values, to calculate the heat loss for the spaces in the building. Calculate the total heating load for a given building, using the drawing layouts on MOODLE. You must select non-biased and reliable sources of information when justifying your analysis. Merit and Distinction grades will only be awarded if the assessor is satisfied that you have reflected on reliable research material (fully referenced) to form the basis of your judgements |
