Intelligent solutions for new and existing buildings
Energy Design
Generation and simulation of detailed design options for optimized planning of the building envelope, energy supply, HVAC systems, and the indoor climate. Energy demand, CO₂ pathway, and life-cycle costs are compared transparently – enabling robust decisions in competitions, schematic design, and investor communications. Priority targets are configurable: CAPEX, OPEX, CO₂.
Detailed options incl. sizing/specification of HVAC systems and the building envelope
Energy / CO₂ / life-cycle cost comparison
CRREM stranding analysis
Energy efficiency class per local standards
Dynamic heating and cooling load simulation
Value Engineering
Optimization of HVAC systems based on dynamic thermal building simulation:
System and component variants are compared using robust KPIs and parameters, precisely sized, and combined into the optimal configuration. Additionally: validation and optimization of the design as well as the heating/cooling load calculation.
Dynamic thermal simulation (8,760 h) and load profile analysis
Variant generation and component benchmarking
Optimal sizing of systems and technical components
Results report including CAPEX/OPEX/LCC and a decision recommendation
More comfort at lower life-cycle costs - up to 10% lower construction costs and up to 30% lower operating costs (project-dependent)
Future-proof buildings
Optimized transformation pathway for existing building stock and portfolios: Dynamic thermal building simulations prioritize measures by impact and cost, operating strategies are refined, CAPEX is planned in phases, and OPEX as well as CO₂ are quantified. CRREM analysis supports compliance and reporting. Operational roadmaps span from quick wins to retrofit stages. Optional: progress is surfaced via live and consumption data (BMS/IoT).

Thermal Comfort
Compliance documentation in accordance with DGNB/ÖGNI SOC1.1 or klimaaktiv D.1-B, based on a full-year dynamic thermal building simulation (8,760 h). Relevant rooms are assessed, comfort hotspots are identified, and optimization measures are derived. Site-specific future-climate data can be incorporated where available.
Compliance dossier for submission to DGNB/ÖGNI or klimaaktiv
Room KPIs & detailed evaluations (e.g., operative temperature, PMV/PPD, overheating hours)
Future climate: scenario analysis based on available site data
Energy Performance Certificates (EPC)
Demand-based Energy Performance Certificates (EPC) in accordance with DIN 18599, generated directly from the digital twin—consistent, auditable, fast. GEG-compliant (Germany) for residential and non-residential buildings. Ideal for existing buildings, refurbishments, and design – including direct variant comparison for leasing, sale, and financing.
Data foundation from the digital twin (geometry, constructions, building services/MEP)
Modeling and energy balancing in accordance with DIN 18599 (GEG)
Demand-based EPC, documented with an audit trail
Variant comparison (existing/retrofit/design) with key metrics
BIM Model
Generation or digitization of data from plans (e.g., PDF, DWG) – according to Optimuse standards or customer-specific client information requirements (AIA).
BIM models can be used for all Optimuse services and are provided as native ArchiCAD files or IFC models for analysis, tendering, and operation.
