I have made a video of me playing the guitar solo of my latest song “You”, out now! Featuring various techniques (e.g. sweep picking and tapping), diminished and harmonic minor scales.

Room 251 shared in a Spotify playlist
I’m so glad! My dark ambient soundtrack “Room 251”, which is inspired by the movie The Shining (1980) and is dedicated to my friend Fabrizio Borgio, was shared by Otium Musicum Records in their playlist “Lovecraftian Atmos”: https://open.spotify.com/playlist/0cqGsFxFxtnzEYZ98x275q
Thank you so much!
The Tyger is now included into a Spotify playlist
The reworked version of my 2022 song “The Tyger”, my homage to William Blake, is now featured in a Gothic Metal Spotify playlist:
Thank you so much, UNDERGROUND N’ PROUD!

New review for Tyger!
I really wish to thank Metal Junkbox for their nice review of my track The Tyger, my personal tribute to the visionary poet and artist William Blake!
“Today we have a real musical journey, we have Quantum Prana, a musical project that manages to transport the listener through a musical environment that goes from Gothic metal, to psychedelic, with Groove and a lot of creativity, we feel for several moments as a true interspatial journey in a creation that manages to break paradigms and deliver something unique that deserves your attention!
The Tyger (A Tale of Creation) was the song that introduced us to the creative soul of Quantum Prana, a song that is full of elements and nuances, those that labeling would be imprecise and describing would be vague, so listen and draw your conclusions. !!!”
Obrigado, Metal Junkbox!

New publication on energy storage
This paper investigates how a simulated room’s energy and temperature performance are affected if its underfloor heating control is modelled with increasing detail. Experiments were performed to develop and calibrate an empirical model of wax motor and to calibrate the valve curve. These models were used to implement and test the On/Off and proportional-integral (PI) control processes at various levels of modelling detail. Controllers were implemented by gradually adding optimized control parameters, signal delay, calibrated valve curve, signal modulation, and actuator modelling. The On/Off control dead band and PI parameters exhibited the largest impact, reducing energy use (1%–5%) and temperature fluctuations (ca 1 K). Modulating the PI output signal increased temperature fluctuations to the same amplitude as On/Off with 0.5 K dead band, increasing space heating demand by 1.3%. The wax actuator counted for less than 1%; however, it increased time delays to maximally 7 min and remarkably changed the mass flows.

New paper published! Energy efficiency, energy transition, emissions reduction
Our newly published paper demonstrates how choosing different #energytransition policies at the European level can radically affect renovation rates, costs, CO2 #emissionsreduction, and #energyefficiency. MDPI TalTech – Tallinn University of Technology Aalto University
Abstract
Energy renovations of the building stock are a paramount objective of the European Union (EU) to combat climate change. A tool for renovation progress monitoring is energy performance certificate (EPC) labelling. The present study tested the effect of different EPC label classifications on a national database, which comprises ~25,000 EPC values from apartment buildings, detached houses, office buildings, and educational, commercial, and service buildings. Analysing the EPC classes labelling resulting from four different EU methods, we estimated the annual renovation rates, costs, energy savings, and CO2 emissions reduction that would affect the national building stock if each of them was adopted, to fulfil the European Climate Target Plan by the year 2033. The ISO 52003-1:2017 two-point and one-point methods determined a very uneven distribution of renovation rates, from 0.45% to ~9%. Conversely, the Directive 15% recently proposed in COM/2021/802 with uniform rates determined smaller differences and standard deviation, not pushing renovations above 3.70%, namely a rate that once fine-tuned can stimulate realistic, yet effective renovation campaigns. The major differences in renovation rates provided by the studied methods show the need for a harmonized strategy such as the Directive proposal to enable achievement of European targets.
