SPD to Examine Energy-Saving Strategies During Cold Weather Season
In the current energy crisis, the environmental spokesman for the SPD city council faction, Manfred Flore, is seeking answers to an important question: Has an evaluation been made of the impact of reducing room temperatures in public buildings on the city's energy demand?
Flore, who also serves as the Mayor of Oberhausen, is concerned about energy scarcity, expense, and the lack of CO-neutrality in the city's energy supply. He is not alone in this concern, as many cities worldwide grapple with the same issue.
To address this, Flore proposes an evaluation of potential hot water savings in public buildings, in addition to examining the energy efficiency of maintaining a maximum room temperature of 20 degrees Celsius during the heating period. Studies suggest that such a measure could yield energy savings of around 6-12% per degree difference from typical lower setpoints [1][4].
For instance, raising the air conditioning temperature from 23°C to 25°C can result in up to 12% energy savings per degree, with no loss of comfort [4]. Similarly, lowering the heating temperature to 20°C may reduce energy use without compromising comfort.
Such energy savings translate directly to proportional reductions in heating energy bills. The exact cost benefits depend on factors such as the size and number of administrative buildings, local energy prices, and the duration of the heating season. For a city with many administrative buildings, a 10% energy reduction over the heating period can result in substantial cumulative cost savings, often running into thousands or millions of currency units annually [2].
Supporting policy guidance from states like Massachusetts and Connecticut indicates that energy efficiency improvements leading to 10-20% savings relative to code baseline result in significant operational cost reductions in public buildings [2]. This reinforces the feasibility and benefit of maintaining controlled, moderate indoor temperatures.
The SPD faction in the environmental committee plans to address this issue in their next meeting, discussing the potential energy and cost savings that could be achieved by reducing room temperature in administrative buildings during the heating period to a maximum of 20 degrees Celsius. They also plan to gather feedback from city employees regarding the reduced temperature in administrative buildings.
Flore is keen to review the energy savings from reducing room temperature in public buildings to 20 degrees Celsius during the winter and 23 degrees Celsius during the summer. This move could represent a meaningful opportunity to reduce energy bills and emissions, although an exact city-wide monetary figure is not yet universally established.

- Applying such energy-saving measures, such as raising the air conditioning temperature from 23°C to 25°C, could result in up to 12% energy savings per degree, with no loss of comfort, while lowering the heating temperature to 20°C may reduce energy use without compromising comfort.
- By reducing energy use in this manner, significant cost savings can be achieved, with a 10% energy reduction over the heating period potentially resulting in substantial cumulative cost savings, often running into thousands or millions of currency units annually for a city with many administrative buildings.
