• Chiller Performance Curve Library: Industry leading tool for loading, visualizing, and customizing polynomial fit curve performance data for HVAC equipment.
• Independent Secondary Hot Water Loops: Capability is expanded with respect to loop temperature controls.
• Hot Water Loop Configuration: Now supports multiple secondary loops, new pre-heating locations, new flow control options, and more.
• Chilled Water Sensible Thermal Storage: Capability for sensible chilled-water storage, in addition to ice storage.
• Scheduled Load Component: Add loads to HWL and CHWL based on hourly or sub-hourly data, modulated design load, or time series of repeating scheduled values.

• Discover the optimal building design parameters that achieve selected objectives
• Automatically runs multiple Apache simulations and learns from each new iteration, discarding the worst results, while keeping the best
• Keeps going iteration after iteration until you have honed in on the optimal solution
• Optimise against any two building-level variables e.g. occupancy weighted comfort, mean comfort, total energy, carbon emissions, seasonal efficiency, lighting/heating gains
• Standard ‘worksheets’ allow non-expert users to access the tool readily
• Fully customisable bespoke ‘worksheets’ can be created and shared internally to deliver quality and repeatability for all users
• Completely customisable even down to the graphics rendered

The Elements tool links the VE to both optimisation Hone and Parametric tools. Elements allows the setting of target parameters (model inputs) and results variables (Vista outputs) for parameteric analysis. The tool works using rules, where it gathers common parameters from the VE, allows the range of the parameter to be set and then defines whether the variable is to be used in the same way for all instances or whether the variable is to be altered independently.

ModelIT now offers the ability to place geometric free-standing panels that are exclusively for estimating PV potential and allows the assessment of PV potential to take the physical location into account. In ApacheSystems Parabolic Solar Collectors adds to the renewables capabilities within the VE and can be used as DHW pre-heater or as a space or process pre-heater.
