  4. 2. Distribution of Ventilation Air and Heat by Buoyancy Forces inside Buildings : An Experimental Study

    Author : Claes Blomqvist; Mats Sandberg; Per Heiselberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building ventilation; thermal forces; buoyancy; gravity currents; large openings; heating; air quality; forced convection; free convection; Building engineering; Byggnadsteknik;

    Abstract : The main task of the ventilation system in a building is to maintain the air quality and (together with the heating or cooling system) the thermal climate at an acceptable level within the building. This means that a sufficient amount of ventilation air at the appropriate temperature and quality must be supplied to satisfy thermal comfort and air quality demands and that this air is distributed to the parts of the building where people reside.

  5. 3. Towards sustainability with building services systems : – by focusing on material choices, energy use and thermal indoor climates in residential buildings

    Author : Mats Dahlblom; Avdelningen för Installations- och klimatiseringslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; residential apartment buildings; building services systems; energy use; hvac; hydronic heating system; heating control; feedback control loop; indoor temperature measurements; individual metering and billing; indoor temperature variations; thermal comfort; vertical temperature gradient; case study;

    Abstract : For a development to be considered sustainable, social, economic and environmental requirements must be met. The Swedish sustainable development goals, based on Agenda 2030, contain 16 national environmental quality goals. The National Board of Housing, Building and Planning is responsible for achieving the goal "A good built environment". READ MORE

  6. 4. Chemically Synthesized ZnO Nanostructures : Realization of White Optoelectronic Devices with High CRI Values

    Author : Sadaf Jamil Rana; Magnus Willander; Omer Nur; Enda McGlynn; Linköpings universitet; []
    Keywords : ;

    Abstract : Recently in a couple of decades, nanotechnology and nanoscience are becoming wide spread fields of research due to the revolutionary advances in the manufacturing processes which enable the realization of infinitesimally modest nanodevices holding a huge variety of fascinating properties and applications. Besides various functional materials, ZnO has captivated interests for a variety of applications in electronics and optoelectronics owing to its unique characteristics; such as, direct wide band gap, large exciton binding energy, semiconducting, photonic, and piezoelectric properties.
