RIUSKA

This is part of an integrated simulation system for building services design and facilities management. It can be used in everyday design processes and covers the thermal simulation needs of the whole-building life cycle. The user can add building envelope materials, internal loads, and HVAC into the created 3D model and perform thermal calculations. RIUSKA can be used for space simulations to dimension cooling or heating equipment, or for energy calculations of the whole building. As a calculation engine RIUSKA is presently using DOE-2.1E.

The IFC file format is used to import the building 3D model into RIUSKA. The 3D model must be created in some IFC-compliant 3D modeling tool. RIUSKA currently supports IFC 2x3 (CoordinationView with SpaceBoundaryAddOnView).

Keywords

Energy calculation, heat loss calculation, system comparison, dimensioning, 3D modeling

Validation/Testing

N/A

Expertise Required

Engineering background needed to analyze calculation results. Programs offer efficient use of default data libraries to help the user to choose input values.

Users

Over 200 in Europe, USA and Australia.

Audience

Design engineers in HVAC design projects and facility managers during operation and maintenance.

Input

The user can either provide input data about materials, thermal loads, schedules, and HVAC or choose from predefined library values.

Output

Several spreadsheets can be produced, presenting inputs used and hourly or yearly values for cooling and heating energy consumption, temperatures, and cooling loads.

Computer Platform

PC-compatible, Windows XP/Vista/Windows7

Programming Language

Visual Basic

Strengths

Simple interface structure and the possibility to use default library values enable quick access to space and building simulations.

Weaknesses

Only the predefined HVAC systems are available.
