Boreholes

The Boreholes extension allows you to predict the performance of large fields of interacting boreholes in a single simulation. The model handles both straight and slanted holes in homogeneous ground.

Each individual hole (single or double U-pipe) is modelled using 2D cylindrical coordinates. By using superposition and mirroring techniques, the full 3D temperature field - with the correct thermal response in all timescales - can be computed and visualized in 3D.

By simultaneous (fully coupled) simulation the borehole field, plant as well as the building , it is possible to take realistic account of heat pump capacity and COP dependence on borehole return temperature. Control strategies can also be applied to keep the ground temperature at an optimal level for both heating and cooling. These critical effects cannot be studied by the commonly used approach of first calculating the load from the building and then applying it to a separate borehole model.

A simplified version of the borehole model, limited to a single hole, is distributed with the IDA ICE Standard edition.

ASHRAE 90.1

The ASHRAE 90.1 extension helps to perform the Building Performance Rating Method in Appendix G of ASHRAE 90.1-2016, which is used in Green Building Programs like LEED.

LEED is complicated!

But when you get a license from us, we will provide you with both a sophisticated software and great know-how.

A template simplifies the creation of the Proposed Building model and the extension automatically converts it to a Baseline Building, according to Appendix G. The conversion includes database support for envelope properties and space types as well as automatic HVAC-system selection and rescaling of windows and skylights. Design runs to decide equipment capacities and annual simulations for four directions are done automatically. Reports are designed to fit with LEED submittal forms and other resource documents on LEED Online.

Slab Cooling and Heating

The Slab Cooling and Heating extension allows you to handle embedded heating and cooling systems (TABS) – both water based and electrical.

Separated water based cooling panels and radiators are available in the Standard edition, while the Slab Cooling and Heating extension adds the possibility for combined heating and cooling panels.

Enhanced Window Models

The Enhanced Window Models extension allows for openable windows and doors. It provides natural ventilation controlled by schedules (arbitrary control function block diagrams with the Expert edition).

It can also be used to simulate ventilated double skin facades and other complex glass facades. A detailed pane-by-pane window model according to ISO 15099 is included, allowing for more realistic and detailed simulation of windows. Properties for each layer (panes, cavities and shades) can be defined, making it possible to construct arbitrary window configurations. An extensive database is included.
