Assignment Task:
Define the term 'design brief'. Explain the significance of including these subjects in the brief, what is the purpose of the brief, who are the parties that would have an interest in it, and at what stage of the project would it be issued. As part of the design brief, it is often necessary to advise the client and the architect on the factors that are within their control and that will affect the services design. Based on the information in the scenario, prepare a short report detailing the information required from both parties, and explain the why each set of information is required. You will need to address factors such as incorporating the clients own specification where necessary, the type of client and how this will affect the aspects of the design, the local utility infrastructure, building occupancy, room data sheets, a particular design that the client favours or has used/seen installed elsewhere, geographical location, planning drawings, U values specified by the architect and other overriding energy targets imposed on the project. Your answer should make reference to the BSRIA Design Framework for the project stages. Whilst the information that you choose to discuss, may vary the following must be considered: The control strategy; The maintenance expectations of the proposed services; The use of new technology/ sustainable features/bespoke installations. Include an analysis of the factors that affect human comfort. Your analysis must include the physical factors and the personal factors and the way in which these factors are recorded, monitored and addressed. Include in your analysis research into the occurrence of sick building syndrome and the emergence of the WELL assessments of the internal environment.
Using the drawings and scenarios, produce a database of information that will be required for the calculation process and include the research by which you have derived this information. Your database must include values for U values, infiltration rates, fresh air requirements, occupancy, building dimensions, legislative targets such as the building regulations, usage of the building, as a minimum. Your client is required to meet regulatory parameters within the workspace conditions. You will need to evaluate the minimum and maximum internal air temperatures, and surface temperatures, humidity, noise, air pollution, safety, as required by legislation. Include reference to the relevant regulation/legislative document. Calculate the overall thermal conductivity of the structures that have been proposed by the architect. Compare the values against the requirement under the Building Regulations Part L.
Using your database and research calculate the conductive and convective heat loss for the building. Calculations must include the CIBSE TM23 method for infiltration rate calculation and reference to the data needed to derive this information. Comment on dynamic heat loss vs steady state and explain why you have used the latter in your calculation. Calculate the total heating load, as required to offset the heat losses from the building and to ensure the occupants have a supply of fresh air to meet their needs.
Based on the U values calculated, provide details of the changes to the design of the wall and roof structure, to ensure that the U value meets limiting elemental statutory requirements and passive house standards. Calculate the annual cost of the heat lost through the wall and roof of a complaint building and compare this with the costs through a passive house structure.
Identify two legislative documents, one of which may be an act of parliament that applies to the EezeeExport.net building. Describe the structure of the documents, latest issue, the general scope and an analysis of the application of each document to the building.
