Further fundamentals
The software we have developed for sizing and calculating the cost-effectiveness of interrelated energy systems delivers results in terms of energy input and costs. The heat and electricity demand is calculated first. A database of buildings, heat consumption, electricity consumption, heat pumps, PV, solar thermal modules, CHP units, boilers and electricity tariffs is available. The database data can be individually adapted and updated. Every variant can be calculated — from a single-family home to the central supply of a housing development or municipality, right through to supplying an industrial estate. Alongside new builds and existing buildings, retrofits can also be taken into account.
The software is being further developed by INEKON – Intelligente Energiekonzepte.
The engineering background behind the calculations is described in the Fundamentals section: climate data, heat and electricity demand, heat pumps, CHP units, solar collectors, photovoltaics, boilers, buffer and battery storage, hydraulic schemes, the energy balance comparison and the economic analysis.
Standards and data sources
- VDI 2067 for the cost calculation and the annuity method
- EN 12975-2 for collector efficiency figures
- DIN 6271 for the altitude correction of engine output
- PVGIS and Meteonorm for irradiance data
- VDI 3805 and manufacturer data for component characteristics
