Javad Darvishi

PhD Research Fellow

PhD Student

H4057 ( Jon Lilletuns vei 9, Grimstad )
Office hours:

Master’s degree in Sustainable Architecture from Norwegian University of Science and Technology (NTNU), bachelor’s degree as engineer in building physics and construction from Western Norway University of Applied Sciences (HVL) and BREEAM NOR certificate as Accredited Professional.

I am currently working on PhD research project which is about CLT (Cross Laminated Timber) and impact of the wood surfaces on indoor environment and human health / comfort.

Research interests

My research interests are thermal analysis and impact of hygroscopic properties of materials such as wooden materials on heating demand. I have experience in different thermal analysis programs, moisture risk analysis / assessment and mould growth evaluation of building materials and mapping of hazardous materials and environmental awareness in building process and management.

KL-Tre Smart (2018-2022): This project will investigate how the hygrothermal properties of wood influences the heat transfer through wooden walls. We will in laboratory conditions investigate the amount of heat passing through CLT (Crossed Laminated Timber) elements when it is exposed to realistic climatic conditions on both sides of the wall. The methodology for measuring U value of the walls has been used in an office building constructed of CLT elements without insulation or cladding. During these measurements, plate sensors were used to measure heat flux (W/m²) and temperature sensors were used to measure the temperature differences across the wall. This is a measuring method where the measurement uncertainties during field conditions are not well documented.


Build In Wood (2019-2023): 

Build-in-Wood is a European funded Horizon 2020 project with the goal of drastically increasing the proportion of timber construction. With the urban population steadily growing and climate change becoming a pressing topic, our challenge is to offer high-quality, affordable and environmentally friendly housing. Green Building is the future: Timber is such an attractive material because it has a low carbon footprint, uses little energy and water and is 100% renewable from sustainably managed forests.

My research area is to find a optimal use of nature-based insulation in prefabricated wall systems, such as stud-wall and CLT insulated wall systems.
