Hi All,
We are going through a factory project having 3 major workshop buildings. There is no provision for space cooling by direct expansion or chilled water like cooling system. In place of that space environment is maintained by evaporative cooling where Ventilation air flow is calculated by temperature rise method (5-degree temperature difference) & HVLS fans (some portions). how will we define a base case for this kind of system?
1. Will base case be define based on Built up area, facility type and climate zone considering proposed case as a part of HVAC system (according to ASHRAE 90.1-2016)?
Please suggest a better way to define base case system for such peculiar facilities.
2. Since there is no common higher side in proposed design to serve all the workshops, can the workshop buildings be modelled separately for energy modelling (individual i/o file for each workshop) and if it is possible what will be the scenario of base case model? OR it would be better to make all the workshops as a block under single building? (as we are using Design builder Energy plus for our building simulation)
We appreciate your suggestions on the above points.
