Building occupant transient agent-based model – Movement module
(Journal article; Peer reviewed, 2020)Simulation of occupant behaviour (OB) in buildings is a challenging task. Available software uses a broad spectrum of tools that try to reproduce the patterns of human activity. From building energy perspective, the main ... -
Comparative study on the thermal behavior of untreated and various torrefied bark, stem wood, and stump of Norway spruce
(Journal article; Peer reviewed, 2017)In this work, the torrefaction of different parts of Norway spruce (stem wood, bark, and stump) was studied. Three different torrefaction temperatures were applied: 225, 275, and 300 °C with 30 and 60 min isothermal periods. ... -
Data-Driven Real-Time Price-Based Demand Response for Industrial Facilities Energy Management
(Journal article; Peer reviewed, 2021)Recent advances in smart grid technologies have highlighted demand response (DR) as an important tool to alleviate electricity demand–supply mismatches. In this paper, a real-time price (RTP)-based DR algorithm is proposed ... -
Effect of torrefaction on physiochemical characteristics and grindability of stem wood, stump and bark
(Journal article; Peer reviewed, 2017)In this work, Norway spruce stem wood, stump and bark were torrefied in a bench scale tubular reactor at 225, 275 and 300 °C with two residence times (30 and 60 min). Effect of torrefaction on general properties, chemical ... -
Evaluation of “Autotune” calibration against manual calibration of building energy models
(Journal article; Peer reviewed, 2016)This paper demonstrates the application of Autotune, a methodology aimed at automatically producing calibrated building energy models using measured data, in two case studies. In the first case, a building model is de-tuned ... -
Experimental test of a black-box economic model predictive control for residential space heating
(Peer reviewed; Journal article, 2021)Previous studies have identified significant demand response (DR) potentials in using economic model predictive control (E-MPC) of space heating to exploit the inherent thermal mass in residential buildings for short-term ... -
Global sensitivity analysis and optimal design of heat recovery ventilation for zero emission buildings
(Peer reviewed; Journal article, 2023)Energy-efficient building services are necessary to realise zero-emission buildings while maintaining adequate indoor environmental quality. As the share of ventilation heating needs grow in well-insulated and airtight ... -
High temperature gasification of high heating-rate chars using a flat-flame reactor
(Journal article; Peer reviewed, 2018)The increasing interest in gasification and oxy-fuel combustion of biomass has heightened the need for a detailed understanding of char gasification in industrially relevant environments (i.e., high temperature and ... -
Implementation of CCPP for energy supply of future building stock
(Journal article; Peer reviewed, 2015)European Directive 2010/31/EU stated that by the end of 2020 all new buildings should be nearly Zero-Energy Buildings (nZEB). Since such buildings require a low quantity of energy for heating, they can utilize energy from ... -
Life cycle assessment of transport of electricity via different voltage levels: A case study for Nord-Trøndelag county in Norway
(Journal article; Peer reviewed, 2015)Electricity transmission and distribution (T&D) plays a vital role in society by connecting electricity producers and consumers. We present a life cycle assessment case study of electricity delivery to consumers in ... -
Minimizing delivered energy and life cycle cost using Graphical script: An office building retrofitting case
(Peer reviewed; Journal article, 2020)Selecting the most cost-effective retrofit interventions to achieve a significant reduction of energy use and CO2 emissions in the building sectors is challenging, because a large number of possible retrofitting options ... -
Model complexity of heat pump systems to investigate the building energy flexibility and guidelines for model implementation
(Journal article; Peer reviewed, 2019)Building performance simulation (BPS) is a powerful tool for engineers working in building design and heating, ventilation and air-conditioning. Many case studies using BPS investigate the potential of demand response (DR) ... -
