Building technology in the integral planning process

Specialist planner

As a specialist planner in building technology, you are an expert in energy efficiency, comfort, and sustainability. You combine architecture, building physics, and technology into an efficient, sustainable overall system. You develop energy-optimized concepts, calculate heating and cooling loads, and plan associated pipe networks using modern HVAC planning software. You integrate your results directly into the MEP BIM workflow. With pitCAD Ultimate, SOLAR-COMPUTER, and the Autodesk AEC Collection, you have tools at your disposal that link modeling, calculation, and documentation.

pitCAD ULTIMATE/CLASSIC

Model-based TGA planning with a system

With pitCAD Ultimate, you can implement technical planning in the building model. You create plant models, surfaces and technical systems in a shared CAD environment and use these as the basis for calculations and documentation. Thanks to the openBIM capability, smooth data exchange via IFC exchange format is guaranteed. Whether heating, cooling, ventilation or sanitary planning, pitCAD Ultimate ensures transparent, traceable processes and reduces planning errors thanks to consistent data. 

Interfaces to SOLAR-COMPUTER, etap CANECO and DIALux create a fully integrated planning process across all trades - from network and lighting calculations to detailed technical building services planning.

SOLAR-COMPUTER

Technical calculation at the highest level

The SOLAR-COMPUTER heating/cooling load calculation software is an indispensable tool for you as a specialist planner. The software covers all relevant standards and procedures, from heating load calculation and dynamic heating and cooling load calculation to pipe network calculation, including circulation calculation for hot and cold water. Thanks to the close integration with pitCAD Ultimate or Revit, a digital data network is created that significantly increases the quality of planning. As a specialist planner, you benefit from a high level of calculation depth, automatic plausibility checks, and compliant documentation. Thanks to the connection between the model and the calculation, the database remains consistently up-to-date. Changes in the model are incorporated, making your planning significantly more efficient and secure.

Autodesk AEC Collection

BIM environment for specialist disciplines

With the Autodesk AEC Collection, you have access to a uniform BIM platform that seamlessly integrates architectural models, technical systems and calculation data. As the leading BIM platform, the Autodesk Architecture, Engineering & Construction Collection (AEC) offers specialist planners the opportunity to network architecture, structural engineering and MEP in a common environment. In combination with Revit and SOLAR-COMPUTER, this creates a fully integrated planning process.
