  2. 6. Responsible resource management in hotels : attitudes, indicators, tools and strategies

    Author : Paulina Bohdanowicz; Björn Palm; Ivo Martinac; Walter Jamieson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hotels; energy and water management; energy and water conservation; environmental awareness; environmental reporting; performance indicators; consumption modelling; benchmarking; Mechanical energy engineering; Mekanisk energiteknik;

    Abstract : Hotels constitute one of the main, and still expanding, pillars of the tourism sector and are highly unique among other commercial buildings. Resource intensive and frequently inefficient systems and operational routines applied in the sector, result in considerable environmental impact and indicate an urgent need for more environmentally sound practices and products in the hotel industry.

  4. 7. Modelling the dynamics of domestic low-temperature heat pump heating systems for improved performance and thermal comfort : a systems approach

    Author : Dimitra Sakellari; Per Lundqvist; Savvas Tassou; KTH; []
    Keywords : Technology; heat pump; domestic heating and ventilation; low-temperature hydronic heat distribution; systems approach; integration; simulation; energy efficiency; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The present environmental concerns and the rising human requirement for solutions with better comfort and lower costs have resulted in an increased awareness for the energy use in the built environment. Technical advances in building structural systems and materials, heating and other comfort-providing systems and controlling strategies all lead to the integration of building technology with the function of buildings and the aesthetics.

  5. 8. Strengthening and degradation mechanisms in austenitic stainless steels at elevated temperature

    Author : Muhammad Farooq; Rolf Sandström; Göran Engberg; KTH; []
    Keywords : ;

    Abstract : With rapid economic developments and rising living standards, the demand for electricity all over the world is greatly increased. Due to high fuel costs, the steam boilers with higher steam temperature and pressure are needed to decrease the cost of power generation throughout the world extensively. READ MORE

  6. 9. Making visible the invisible : Health risks from environmental exposures among socially deprived populations of Nairobi, Kenya

    Author : Thaddaeus Wandera Egondi; Joacim Rocklöv; Nawi Ng; Remare Ettarh; Patrick Kinney; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; air pollution; urban health; temperature-related mortality; particulate matter; exposure assessment; child health; Epidemiology; epidemiologi; folkhälsa; Public health;

    Abstract : Background: Most countries of sub-Saharan Africa (SSA) are experiencing a high rate of ur­banization accompanied with unplanned development resulting into sprawl of slums. The weath­er patterns and air pollution sources in most urban areas are changing with significant effects on health. READ MORE
