ESP-r Training Course

Write a report on your results and send to your tutor:

+ State the name of the directory containing your model and give a brief description of the building you are modelling, including the design change you made.

+ Analyse the building performance on a cold winter day before and after your imposed design change. Report maximum heating load, the energy consumption for heating during the day, comfort assessment results assuming a person is engaged in sedentary work (i.e. activity level = 1 met, which is about 58 W/m^2 of body surface) while wearing typical winter indoor clothing (i.e. clothing thermal resistance level = 1 clo); and the clothing level which would be required in order for the predicted percentage of dissatisfied (PPD) occupants to be less than or equal to 10% during normal working hours (9:00 until 17:00).

+ Report the frequency distribution of the inside air temperatures (i.e. the number of hours each temperature band occurs) for the period July 1 to July 15 inclusive. Assume that the building temperature is free-floating (i.e. no control is imposed).

Aim	To consolidate the understanding of the overall simulation procedure.
Learning Outcome	Ability to utilise the elements of the ESP-r system in an efficient manner.

Task	Instructions
1. Create a 2-zone problem.	Starting from scratch, sketch out the form and composition and schedules for a two zone model of your own design. From these sketches and notes, create the required geometry, construction and operation from each zone and ensure that the zones are linked together as required. Then impose a simple heating system control similar to that considered in Assignment 11. Note that real problems will generally have more than two zones. The planning and consistency checking skills you learn in this two zone model will become more and more important as the number of zones and surfaces and controls increase.
2. Simulate for typical seasonal conditions.	Select appropriate climate sequences using the climate assessment module and use either the simulation presets or an Integrated Performance View to record typical assessment weeks.
3. Carry out a performance evaluation.	Select appropriate measures of performance (temperatures, energy consumption, heating loads, comfort etc).
4. Investigate a parameter variation.	Alter one of the design parameters. Repeat the simulation and analysis steps. Evaluate the change in the selected performance indices (for the same simulation presets).
