DTU Civil Engineering’s Section for Indoor Environment and Building Physics invites applications for a 3-year PhD position starting December 2017 on ‘Synthesis, characterization and application of composite phase change humidity control materials’

The Section for Indoor Environment and Building Physics is a world leading research centre on indoor environment and energy.  Research activities of the Section provides planners and manufacturers of buildings, building components and HVAC systems with new ways to achieve optimal indoor environments through design and by the operation of low-energy buildings and energy-efficient HVAC systems. The Section comprises world leading researchers in building physics who do experimental and modeling work to optimize the performance of building envelope structures and the materials therein.

Project Description
In order to curtail the growth of CO2 emissions from the building sector, it is essential to improve the energy efficiency of buildings and reduce the use of energy in HVAC systems. One way this can be achieved is through the introduction of innovative passive building materials that can regulate both the indoor temperature and humidity, and maintain the indoor environment at a stable and comfortable level.

The loads of HVAC systems consist of sensible (“dry”) load and latent load (involving evaporation/condensation of humidity). Previous studies of passive materials mainly focus on one individual load (either sensible or latent). For the sensible heat transfer, materials with large heat capacity have been proposed. Traditional  phase change materials (PCM) can absorb or release large amounts of sensible heat, whilst maintaining the temperature of the materials constant during the phase change process. Thus, PCMs can be used to regulate indoor temperature fluctuations and consequently reduce the sensible energy consumption.  For the latent heat transfer, porous materials with high adsorption ability have been recommended. These hygroscopic materials can absorb or release large amounts of moisture from indoor air, and can be used to moderate the indoor relative humidity fluctuations. However, heat and moisture transfers in buildings are highly coupled; and do exert an effect on each other.

The main purpose of the study is to develop a novel green building material that autonomously control both the indoor temperature and moisture fluctuations, and improve the indoor comfort and building energy performance. The research will be carried out by combining activities to develop prototype material composites with experimental work and simulation to analyze the performance of the new materials.

Qualifications
Candidates should have a master's degree in mechanical, civil, materials, environmental or chemical engineering. Candidates with knowledge in HVAC systems and material testing, and with experiences in simulation work will be preferred.

The candidates are expected to have good background in experimental work and be interested in an experimentally based PhD working both in mechanical and material testing laboratories.

Approval and Enrolment
The scholarship for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. For information about the general requirements for enrolment and the general planning of the scholarship studies, please see the DTU PhD Guide.

Assessment
Assessment of the applicants will be made by the following professor Carsten Rode, associate professor Menghao Qin and associate professor Jianhua Fan.
