Reduce energy costs in your existing buildings with QWTOOL.
The digital energy auditing tool identifies functional faults & optimization opportunities - and quantifies the savings potential in kWh.
QWTOOL makes systematic energy optimization measurable, recurring, and easy to implement. No new hardware or installation is required – get started directly with existing systems and data.
Through regular energy audits, at least twice a year, QWTOOL identifies faults and optimization opportunities in the building's heating, cooling and ventilation systems.
Each action is assigned a calculated savings potential in kWh, making it easier to prioritize, implement, and follow up on the right actions.
How it works
Subscribe to QWTOOL subscription
Create an account and select buildings for subscription
Register building data
Before the first energy scan, configure QWTOOL with building data information. Each building gets a unique set.
Energy savers
Rounds start with reading or measuring temperatures in the facility using handheld instruments. The operating status of the facility is indicated.
Optimize setting values & fix functional errors
QWTOOL identifies and presents faults as well as optimization opportunities during the survey. Adjust settings and rectify detected faults. The potential for savings is calculated and displayed in kWh.
QWTOOL creates report
When the survey is complete, you receive a clear report that summarizes the building's status, detected deviations, and estimated energy-saving potential in kWh.

Energy consumption (kWh/m2 *year)
Systematic recurring energy optimization starts in year 2
The example shows how energy consumption is reduced by approximately 10% in year 2 when systematic energy work with QWTOOL is initiated.
The lower level of energy consumption can be maintained as long as the recurring energy work continues.
With QWTOOL, we not only offer a solution to reduce energy costs, but we also help companies take a step forward in their sustainability work. With simple and efficient optimization of energy usage, QWTOOL is the obvious choice for everyone who takes energy efficiency seriously.
