syte Renovate Overview
syte Renovate is a comprehensive building renovation planning platform that simulates energy demand, evaluates renovation measures, and provides detailed economic analysis for improving building energy efficiency. This guide provides an overview of the platform's capabilities and technical foundation.
What is syte Renovate?
syte Renovate generates individualized renovation plans for every residential building in Germany. It combines building physics simulations, energy demand calculations, and economic analysis to provide:
- Energy Demand Analysis
Hourly simulation of heating, hot water, and electricity consumption
- Renovation Recommendations
Optimized measures for building envelope and technical systems
- Economic Evaluation
Investment costs, subsidies, utility savings, payback period, and value increase calculations
- Funding Optimization
Automatic calculation of KfW and BEG subsidies
Core Features
Energy Simulation
Hourly calculation of energy flows using surface-based approach:
- • Heat loss through building envelope (U-values from TABULA database)
- • Solar gains through windows
- • Hot water demand (DIN V 18599 Part 10)
- • Heating system efficiency analysis
Building Envelope
Comprehensive renovation options for all building components:
- • Facade insulation (12-26 cm, various standards)
- • Roof/attic insulation options
- • Basement ceiling or wall insulation
- • Window replacement (3-layer glazing)
Technical Systems
Modern heating and renewable energy systems:
- • Heat pump planning with COP calculation
- • PV system sizing and orientation analysis
- • Battery storage recommendations
- • Pellet and district heating options
Economic Analysis
Comprehensive financial evaluation including:
- • Investment cost calculation including subsidies
- • Utility cost savings projection
- • Property value increase (via PriceHubble)
- • Amortization period analysis
Technical Foundation
Energy Calculation Methodology
syte Renovate uses a surface-based approach to calculate building energy requirements:
Heat Loss: Q_T = U × A × F where: • U = Heat transfer coefficient (W/m²K) • A = Surface area (m²) • F = Reduction factor Solar Gains: Q_s = g × A × G where: • g = Total energy transmission • A = Window area (m²) • G = Solar radiation (kWh/m²)
The system performs hourly simulations throughout the year to calculate the projected utility costs, considering:
- Building Data
Construction year, geometry, component U-values from Tabula database
- Climate Data
Location-specific weather patterns and solar radiation
- Usage Patterns
Occupancy-based heating, hot water, and electricity profiles
Renovation Standards
syte Renovate offers four KfW efficiency house standards:
Advanced Features
