Maximise Your DGNB Score with IES Software

DGNB Energy Modelling Software for Every Quality Criterion

Trusted Technology for DGNB Certification

DGNB is one of Europe's most rigorous and holistic green building certification systems. Unlike systems that focus primarily on environmental metrics, DGNB evaluates buildings across environmental, economic, socio-cultural, technical, and process quality - requiring detailed, auditable simulation evidence at every stage.

IES provides an integrated solution that aligns directly with what DGNB demands: high-fidelity energy models, comfort and daylight analysis, indoor air quality evidence, and climate resilience simulations - all from a single coherent digital model.

Supports up to 70% of DGNB total scoring potential

Evidence across ENV, ECO, SOC, TEC and PRO criteria

Aligned with DGNB 2025 and Danish BR18 requirements

Auditable outputs accepted by DGNB auditors

How IESVE Contributes to DGNB Criteria

Across ENV, ECO, TEC, PRO and SITE, IESVE can substantively support up to 70% of total scoring potential, depending on project scope and documentation strength.

Environmental Quality

Operational energy, envelope performance, ventilation and microclimate.

Economic Quality

LCC inputs, climate resilience and adaptability modelling.

Sociocultural Quality

Thermal comfort, daylight, IAQ and user wellbeing.

Technical Quality

System performance, control strategies, metering and resilience.

Process Quality

Commissioning, handover, traceability and risk scenario evidence.

Site Quality

Microclimate, heat-island mitigation, shading and outdoor comfort.

Scoring Potential by Criterion

A criterion-by-criterion view of where IESVE delivers simulation evidence and the scoring potential it unlocks.

Category	Criterion	What is evaluated	Scoring potential	Impact
ENV	ENV1.1Climate action & energy	Whole-life carbon & operational energy (LCA)	90–100 pts	High
ENV	ENV1.2Local environmental impact	Emissions related to energy systems	20–75 pts	Medium
SOC	SOC1.1Thermal comfort	Indoor thermal comfort during occupancy	Up to 100 pts	High
SOC	SOC1.2Indoor air quality	Ventilation performance and pollutant levels	30–65 pts	Medium
SOC	SOC1.4Visual comfort	Daylight availability, spatial autonomy and glare	Up to 100 pts	High
TEC	TEC1.3Building envelope	80–90 pts	High
TEC	TEC1.4Building technology	Efficiency of building services and systems	Up to 90 pts	High
ECO	ECO1.1Life cycle cost	Energy demand and system sizing as LCC inputs	30–50 pts	High (input driver)
ECO	ECO2.1Adaptability	Flexibility, change of use and adaptability	Up to 100 pts	High
ECO	ECO2.6Climate resilience	Climate resilience and future weather adaptation	80–90 pts	High
PRO	PRO2.3Commissioning & monitoring	Energy monitoring, commissioning and verification	30–65 pts	Medium

Scoring potential figures are estimates based on simulation-dependent criteria. Actual points achievable depend on project scope, evidence quality and auditor assessment.

Case Study

IESVE in Action

ROCKYWOOD - Offenbach am Main

IESVE enabled ibak Hamburg GmbH to accurately model, optimise, and validate thermal and daylight comfort for the ROCKYWOOD project in Offenbach am Main. Through dynamic simulation, the team demonstrated compliance with DGNB SOC criteria, ultimately achieving DGNB GOLD certification with a 68.8% degree of fulfilment.
