Logistics center in Regensdorf - How a precise building simulation saves over CHF 20,000 per year

Energy model of the logistics centre in Regensdorf

When connecting renovated buildings to a district heating network, the biggest cost drivers often lie not only in energy consumption but also in the contractually agreed connection fees. These are often based on the maximum heating output. Sizing based on inaccurate data or static assumptions can therefore lead to unnecessarily high fixed costs for years to come.

The starting point: Planned district heating connection based on the existing infrastructure.

For a logistics center in Regensdorf, connection to the local district heating network was planned as part of a renovation concept. The basis for contract negotiations with the energy supplier was the existing heating capacity of the old system, which was 510 kW. Our client, Norm Technologies AG , aimed to precisely determine the building's actual future heating requirements, taking the planned renovation measures into account, in order to avoid costly oversizing and unnecessary connection costs.

Our solution: Needs-based design through dynamic building simulation

To create a data-driven and standards-compliant basis for decision-making, BOP was commissioned to determine the necessary connected load using a dynamic building simulation. This approach is a key component of our "Resizing Heating and Cooling Capacity" service.

Our approach included:

1. Efficient building modeling: Based on the BIM building model provided by Norm, we directly generated the energy model - quickly, consistently and without re-processing the model.

   
   

2. Dynamic analysis : Instead of relying on static values, we simulated the building's heating power requirements, taking into account the planned renovation measures, current and future climate data, and the customer-specific usage patterns of the logistics center.

   
   

3. Load optimization : By evaluating different scenarios, the minimum required connected load was determined to ensure safe operation without loss of comfort.

Another view of the energy model

The result: A reduction in connected load of over 40%

The simulation results revealed enormous optimization potential. Instead of the original 510 kW, the planned renovation measures, taking into account customer-specific usage patterns, will only require 300 kW of connected load. This corresponds to a reduction of 210 kW, or over 40%.

The added value: Long-term cost advantages and planning security

For the operator of the logistics center, this result means direct and recurring financial relief:

• Savings of over CHF 20,000 per year in connection fees alone.

• Avoidance of unnecessary investment and operating costs.

• Planning security through a reliable, standards-compliant basis.

This project is a clear example of how a targeted investment in precise, dynamic simulation leads to significant and long-term cost savings and substantially improves the economic viability of a renovation.
