Autumn 2020ENGG947Advanced Building Design for Energy Efficiency and SustainabilityAssignment 2 (Group project – 3 students per group): “Modelling ofdesign improvements for the 2018 Solar Decathlon Middle East house”Submission details and dates for assignment 2• Project report: A day after Week 13, by 11.59pm on Saturday 13th June 2020.Your report should be submitted on Moodle. All simulation model files shouldalso be uploaded on Moodle (if size of files is too large you can send the fileswith dropbox or any other cloud service). Each report must also contain a“Group Self Assessment” form which is available from Moodle. Studentsshould also submit at least a page with meeting minutes that include the datesgroups met, the students present in the meeting (digital meetings, Facebookchats, or teleconferences count as meetings) and the main points of thediscussion.• Oral presentation: Those can be preferably pre-recorded and sent to us at thesame time as the report and in the same way (deadline: a day after Week 13, by11.59pm on Saturday 13th June 2020). If this is a problem then we can simplyorganise a suitable time and assess your presentation via ZOOM.• Please ZIP/compress all of your files in the same folder to ideally submit onecompressed folder rather than many files separately.Note: This assignment requires significant effort so make sure you start working on it inadvance.[Penalty for late submission 5% of total assignment mark per calendar day late]Starting pointIn this assignment, you should use the OpenStudio energy modelling software to analysedesign improvements of one of the designs of the Dessert Rose Solar Decathlon house.Videos with instructions on how to install and use OpenStudio are available on Moodle. Abaseline model has been prepared for you and you can download it from Moodle(TranslatedPassiveSDMEmodel_2020.osm file) together with the weather file (.epw format)for the location of the competition.Tasks1. The baseline model from Moodle is missing some basic information for the internalheat gains from occupants, lights and equipment.Add the following three (3) occupancy scenarios to your baseline model:i. No occupants;ii. 2 occupants present all day;iii. 30 occupants from 9:00AM to 6:00PM and no occupants from 6:00PM to9:00AMYou should now have three (3) baseline models for the remaining tasks of thisassignment.2. For all 3 baseline models with the different occupancy scenarios run a simulationwithout adding any heating or cooling systems and present meaningful graphs andstatistics of the building thermal performance over the year. You should especiallyinclude the results for the indoor air temperatures and relative humidity % in youranalysis and some discussion of the main findings in relation to the building design.Make sure the graphs are displayed well and deliver a meaningful message to thereader. You will need to include the following two (2) periods in your analysis:a. the annual period of the simulation; and,b. a hot and humid day. The hot and humid day should be selected from theclimate files by running some preliminary simulations to extra relevant climateresults and the data for the selected day should be summarised in the report(e.g. graphed).3. Following the Solar Decathlon rules for thermal comfort (available on Moodle andonline), add an ideal heating and cooling system in your model and determine theenergy required for heating or cooling to bring the temperature and humidity to thelevels required by the competition rules. You will need to provide and discuss theresults for space thermal energy requirements for all 3 baseline models with thedifferent occupancy scenarios.4. Suggest and model six (6) building design alternatives (improvements) that wouldcomply with the competition rules and would at the same time improve the results thatyou generated for the baseline designs for points 2 and 3 above. List yourassumptions and discuss your findings. Suggestions that cannot be modelled shouldnot be included here.5. Critically discuss any potential drawbacks of the current design in relation to thermaland energy performance and suggest areas that need improvement.6. Structure your report in a professional way that provides at least: an introduction ofwhat you have done for each task; meaningful and clear displays of the results, and; acritical discussion of the findings from your simulations.Oral presentation requirementsYou will have to give an overview of the findings you describe in the report. Each studentshould present for 2.5 – 3 minutes. The presentation counts for 12% of the overall subjectmark.Format for ReportThe maximum length of your report is to be 12 pages of A4 including anysketches/diagrams/tables and appendices (excluding group self-assessment form andmeeting minutes pages). The mark for the report and the submission of the simulation modelcounts for 30% of the overall subject mark.Each report must also contain a “Group Self Assessment” form (available from Moodle).Failing to submit the “Group Self Assessment” form will result in a -5% penalty of the totalfinal assignment mark.Each report should also include at least a page with meeting minutes from the Groupdiscussions. This should include the dates groups met, the students present in the meeting(digital meetings or teleconferences count as meetings) and the main points of thediscussion. There will be a maximum mark of 4% given to the submission of the minutes(less than 4% could be given if the minutes are very brief and do not include the basicrequired information).Submission of OpenStudio modelsSubmit all model files, preferably as one compressed file (e.g. zip file), on Moodle. Themodel files include: i) the .osm files, and; ii) the whole model folder that has the same nameas the .osm file. The models will be checked during marking to confirm the validity of theresults that you will include in the report. You should include the following files:• The model files for the 2-occupants baseline model with and without heating (i.e. 2models: the model used for Task 1 and 2, and the model used for Task 3).• The model files you developed to discuss potential design improvements in Task 4. Ifthe file sizes are too large for Moodle you could use alternative ways for submittingthe model files (e.g. submissions with dropbox or Google Drive links will be acceptedin such cases).ENGG947 Advanced Building Design for Energy Efficiency and SustainabilityAssignment 2ASSESSMENT CRITERIA FOR ORAL PRESENTATIONStudent Names ………………………….Assessment Mark ………………………….Assignment 2“Modelling of design improvements for the 2018 Solar Decathlon house”Weighting: 12% of the total subject mark
