    Abstract:

    Here we analyze the life cycle primary energy implication of retrofitting a four-storey wood-frame Apartment Building to the energy use of a passive house. The initial Building has an annual final …

  • life cycle primary energy use and carbon emission of an eight storey wood framed Apartment Building
    Energy and Buildings, 2010
    Co-Authors: Leif Gustavsson, Anna Joelsson, Roger Sathre

    Abstract:

    In this study the life cycle primary energy use and carbon dioxide (CO2) emission of an eight-storey wood-framed Apartment Building are analyzed. All life cycle phases are included, including acquisition and processing of materials, on-site construction, Building operation, demolition and materials disposal. The calculated primary energy use includes the entire energy system chains, and carbon flows are tracked including fossil fuel emissions, process emissions, carbon stocks in Building materials, and avoided fossil emissions due to biofuel substitution. The results show that Building operation uses the largest share of life cycle energy use, becoming increasingly dominant as the life span of the Building increases. The type of heating system strongly influences the primary energy use and CO2 emission; a biomass-based system with cogeneration of district heat and electricity achieves low primary energy use and very low CO2 emissions. Using biomass residues from the wood products chain to substitute for fossil fuels significantly reduces net CO2 emission. Excluding household tap water and electricity, a negative life cycle net CO2 emission can be achieved due to the wood-based construction materials and biomass-based energy supply system. This study shows the importance of using a life cycle perspective when evaluating primary energy and climatic impacts of Buildings.

  • Primary energy implications of different design strategies for an Apartment Building
    Energy, 2016
    Co-Authors: Uniben Yao Ayikoe Tettey, Ambrose Dodoo, Leif Gustavsson

    Abstract:

    In this study, we explored the effects of different design strategies on final and primary energy use for production and operation of a newly constructed Apartment Building. We analysed alternatives of the Building “As built” as well as to energy efficiency levels of the Swedish Building code and passive house criteria. Our approach is based on achieving improved versions of the Building alternatives from combination of design strategies giving the lowest space heating and cooling demand and primary energy use, respectively. We found that the combination of design strategies resulting in the improved Building alternatives varies depending on the approach. The improved Building alternatives gave up to 19-34% reduction in operation primary energy use compared to the initial alternatives. The share of production primary energy use of the improved Building alternatives was 39-54% of the total primary energy use for production, space heating, space cooling and ventilation over 50-year lifespan, compared to 31-42% for the initial alternatives. This study emphasises the importance of incorporating appropriate design strategies to reduce primary energy use for Building operation and suggests that combining such strategies with careful choice of Building frame materials could result in significant primary energy savings in the built environment.
