The adoption of innovation in the building sector is currently too slow for ambitious sustainability goals that our societies have agreed upon. Living labs are open ecosystems real-life environments using iterative feedback processes throughout a lifecycle approach an to create sustainable impact. In context built environment, such co-creative and demonstration platforms needed facilitate innovative technologies concepts more energy-efficient buildings. However, their feasibility not...

The development of smart sensors, low cost communication, and computation technologies enables continuous monitoring accumulation tremendous amounts data for heat pump systems. But the measurements, especially domestic pump, usually suffer from incompleteness given technical and/or economic barriers, which prevents database measurements being exploited to its full potential. To this end, work proposes a data-driven soft sensor approach compensating multiple missing information. sensors are...

International Energy Agency predicts that the global number of installed heat pumps (HP) will increase from 180 million in 2020 to approximately 600 by 2030, covering 20% buildings heating needs. Electric power consumption is one main key performance indicators for pump systems techno-economic perspective. However a common issue prevalent many existing lack electric measurement. The modern installations might be equipped with measurement sensors but this comes at higher system cost...

Digitalization offers new, unprecedented possibilities to increase the energy efficiency and improve indoor conditions in buildings a cost-efficient way. Smart are seen by many stakeholders as way forward. feature advanced monitoring control systems that allow better of buildings’ spaces, but it is becoming evident massive amount data produced smart rarely used. This work presents long-term evaluation building testbed for one year; features state-of-the-art capability local generation (PV)....

As the transition away from fluorinated refrigerants occurs due to F-gas and PFAS regulations, heat pumps face challenge of adapting new non-fluorinated refrigerants.Evaluating pump performance during this is challenging limited operational data on refrigerants.Conducting long-term tests fully understand a pump's with all possible labor-intensive economically burdensome.This study introduces two complementary reduced-parameter models assess across multiple natural despite data.A transfer...

Modern heat pump systems often come equipped with sensors, enabling the collection of substantial operational data.However, many residential pumps installed in preceding decades lack pressure energy meters, or mass flow primarily due to financial limitations.As a result these incomplete measurements, direct analysis system's performance leveraging amassed data for inventive applications like prognosticating consumption, detecting and diagnosing faults, implementing intelligent control...

The adoption of innovation in the building sector is currently too low for ambitious sustainability goals that our societies have agreed upon.The concept smart building, instance, being implemented slowly.One main reasons this technologies to be proven effective and reliable before introduced at large scale buildings.Testbeds demonstrators are seen as a crucial infrastructure test demonstrate impact solutions hence facilitate their buildings.The KTH Live-In Lab platform testbeds designed...
