I’m working on an industrial manufacturing project, located in climate zone 5A, which pursues LEED v3 certification. The project consists of 2,500m2 (26,910 sqft) of office space and 50,000m2 (538,195 sqft) of manufacturing space. Both spaces are heated and cooled. The electrical process load of the manufacturing space is around 2,866 kW.
The issue I’m confronting is that I have several industrial equipment (injection mold which requires 1,000 liters/min of water at 15/20°C; 3,530 liters/min of chilled water for oil cooling; etc.) and I’m not sure how to take them in to account in to my energy simulation for ASHRAE 90.1-2007 compliance.
1) I’m using DesignBuilder v5 for energy modelling but I didn’t find any way to include process energy from industrial equipment. How can I do this in DesignBuilder or Energy Plus?
2) In the baseline case, what system must I use for industrial process energy? Do I have to use the ASHRAE chillers and boilers for chilled/hot water production for industrial equipment or should I use the chillers/boilers from my Proposed case?
3) What else should I do expect considering that my HVAC system is complicated with a large area of solar thermal panels, photovoltaic panels, water to air heat pumps for the space heating and cooling, heat recovery from the chiller condenser etc.?
The project is in the early design stage and not much information is known.
