Distributed Temperature Sensing Method - Usability in Asphalt and Sediment Heat Energy Measurements
(2013)
DiplomityöGeoenergia koostuu maan sisältä tulevasta geotermisestä energiasta ja auringon säteilyenergiasta. Geoenergiaa on saatavilla maasta, kallioperästä, vesistöistä, sedimentistä ja asfaltista. Asfaltti- ja sedimenttilämpö sekä ... -
Numerical simulation of heat recovery from asphalt pavement in Finnish climate conditions
(Elsevier, 31.01.2023)
articleA 3-dimensional mathematical model of asphalt pavement system was developed, based on the fundamental energy balance, to calculate temperatures beneath asphalt surface using hourly measured solar radiation, air temperature ... -
Numerical simulation of the thermal response of seabed sediments to geothermal cycles in Suvilahti, Finland
(Elsevier, 04.12.2023)

(Vaasan yliopisto, 08.12.2020)
ArtikkeliväitöskirjaThis thesis evaluates if novel shallow geothermal energy, specifically geoenergy sources under sediment and asphalt layer, are viable and usable in Finnish climate conditions. The research consists of case studies implemented ... -
Risks of climate change effects on renewable energy resources and the effects of their utilisation on the environment
(Elsevier, 19.01.2024)
articleRenewable energy resources are essential for combating climate change. However, their use, production and collection have environmental impacts and climate change effects also affect them. The unique contributions were ... -
Seabed sediment : a natural seasonal heat storage feasibility study
(Estonian Agricultural University, Faculty of Agronomy, 2017)
articleThe new discovery among renewable energy resources, seabed sediment, has been utilised as a heat source for 42 houses in Vaasa since 2008. Sediment heat is annually loaded by the Sun. In this study the amount of annually ... -
Seabed Sediment as an Annually Renewable Heat Source
(MDPI, 15.02.2018)
