OXPA

OPTIMISED CROSS-PLATFORM ANALYTICS

Our Services in Building Simulation:

1. ✓Sustainability and Climate Protection Strategies: Development and implementation of concepts for CO₂ reduction, net-zero carbon pathways, and greenhouse gas reduction measures.
   

2. ✓Ventilation Simulation and Concepts: Development and optimisation of strategies for natural and mechanical ventilation as well as energy efficiency improvement.
   

3. ✓Thermal and Daylight Simulation: Analysis of temperature progression, thermal comfort, and natural lighting to reduce artificial lighting demand.
   

4. ✓Energy and Heat Demand Calculations: Simulation of heating, cooling, and electricity consumption, as well as optimisation of heat distribution for efficiency enhancement and energy savings.
   

5. ✓Thermal Bridge Calculation: Identification and minimisation of heat losses.
   

6. ✓Moisture Protection Analysis: Prevention of mould formation and structural damage through targeted measures. Additionally, we use data loggers for continuous monitoring of temperature, humidity, and CO₂ to enable comprehensive analysis and optimisation. Moreover, we offer U-value measurement with data loggers from Greenteg to conduct precise thermal conductivity analyses directly on-site.
   

7. ✓Renewable Energy System Simulation: Calculation of energy yield and efficiency of photovoltaic systems, solar thermal systems, and heat pump systems.

Efficient Planning through Modern Simulation Techniques

Optimising the energy performance of a building requires detailed analysis and precise calculations. At OXPA, we utilise advanced building simulations to realistically model the energy demand, thermal behaviour, and indoor climate of buildings. This enables informed decision-making at the planning stage and contributes to the sustainable optimisation of construction projects.
