  2. 22. Assessment of tools for environmentally preferable procurement with a life cycle perspective : the case of acquisition in Swedish defence

    Författare :Elisabeth Hochschorner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Acquisition; Ecodesign tools; Life Cycle Assessment; LCA; MECO; Public procurement; Simplified; Kemiteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : Procurement in public and non-public organisations has the potential to influence product development towards more environmentally preferable products. In 2003, public procurement in Sweden was 28% of GDP. Different types of approaches can contribute some knowledge and thereby facilitate the choice of environmentally preferable products. LÄS MER

    Sammanfattning : Urbanization is a global phenomenon, happening on a massive scale and at a rapid rate, with 68% of the planet’s population predicted to be living in cities by 2050 (UN-DESA, 2018). The sustainability of a city (Goal 11 of UN SDGs) undergoing rapid urbanization depends on its ability to maintain a low consumption of resources and materials at any given time (referred to as the urban metabolic rate), whilst simultaneously providing essential municipal services to its inhabitants, such as a water supply, wastewater treatment and solid waste management.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Buildings; renovation; greenhouse gas emissions; district heating; energy efficiency; building environmental assessment tools; energy use; space heating; life cycle assessment; life cycle costing; payback; scenarios simulation; Byggnadsrenovering; växthusgasutsläpp; fjärrvärme; energieffektivitet; system för miljöcertifiering av byggnader; energianvändning; byggnadsuppvärmning; livscykelanalys; livscykelkostnader; återbetalning; scenariosimulering; Hållbar stadsutveckling; Sustainable Urban Development; Reesbe företagsforskarskola;

    Sammanfattning : Energy use in the European Union is increasing. At the same time, it is estimated that by the year 2050 most of the EU population will be living in currently existing buildings. Some of these buildings are or will be in need of renovation, and they have identified a target to reduce overall energy use. LÄS MER
