  • economic evaluation of the building envelope and operation period of Heating system in terms of thermal comfort
    Energy and Buildings, 2006
    Co-Authors: Gulten Manioglu, Zerrin Yilmaz
    Abstract:

    One of the most important properties of a passively designed building is to provide thermal comfort conditions for users with a minimum Heating Energy cost. Therefore, primary parameters affecting Heating Energy consumption should be determined correctly during the design stage. Building envelope and operation period of the Heating system are important parameters affecting total Heating Energy consumption in the building. In this study, an approach for the determination of the most convenient building envelope-operation period combination in relation to the life cycle cost and climatic comfort is proposed. For the application of the approach, total heat loss and life cycle cost of the building envelope-operation period combinations of a sample building, which is heated intermittently and used during underheated period of the year were calculated and combinations which provide thermal comfort during the occupation period with the minimum life cycle cost are determined as a most convenient combinations. This study is carried out in Istanbul, which is representative city for temperate-humid zone of Turkey.

  • building form for cold climatic zones related to building envelope from Heating Energy conservation point of view
    Energy and Buildings, 2003
    Co-Authors: Gul Koclar Oral, Zerrin Yilmaz
    Abstract:

    One of the most important functions of a building by human beings is to provide thermally comfortable spaces for the users. Therefore, a great deal of artificial Energy is consumed for Heating to satisfy thermal requirements in cold zones. In order to satisfy thermal comfort and reduce Heating Energy consumption at the same time, building parameters affecting indoor climate should be determined properly during the design stage. Building form and building envelope are the most important parameters affecting indoor climate. Building form is an important determinant of total heat loss through the whole building envelope in cold climates. Therefore in this paper, a methodology to determine building form which provides minimum heat loss through the whole building envelope is introduced with its application for Erzurum region that representative city of Turkey for cold climatic zones.

  • predicting the solar Energy and space Heating Energy performance for solid wall detached house retrofitted with the composite edge sealed triple vacuum glazing
    Energy Procedia, 2017
    Co-Authors: Saim Memon, Philip C Eames
    Abstract:

    The UK domestic solid-wall housing stock is a particular focus by reason of its considerable space-Heating Energy consumption than in any other sector because these are so far anticipated to be hard-to-heat. Existing UK solid-wall houses, which have both heritage values and historic fabric, are being improved but yet they tend to have preventable heat loss through windows. This paper takes a comparative analysis approach to envisage space-Heating supply required for achieving thermal comfort temperatures and attainable solar Energy gains to households with the retrofit of the thermal transmittance (U-value) of a new composite edge-sealed triple vacuum glazing i.e. 0.33 Wm-2K-1. 3D dynamic thermal models (timely regimes of Heating, occupancy, ventilation and internal heat gains) of an externally-insulated solid-wall detached house with a range of existing glazing types along with triple vacuum glazing with frame areas are modelled. The predictions of varying window-to-wall ratios on space-Heating Energy and solar Energy gains for winter months are analysed. The results have shown by increasing WWR from 5% to 59%, the winter months space-Heating Energy supply to the solid-wall detached house slightly decreases with triple vacuum glazed windows whilst a gradual rise was noticed with single glazed windows. A small increase in solar gains, i.e. 5.6 kWh, was predicted for a room with a triple vacuum glazed window compared to a triple glazed air filled window. However, with similar increment to WWR, the house achieved higher solar gains with single glazed windows. The notable winter and annual space-Heating Energy savings of 14.58% (EUR 49.2) and 15.31% (EUR 105.4), respectively, were obtained with a solid-wall detached house retrofitted with triple vacuum glazed windows compared to single glazed windows. In the overall fabric heat loss, the heat loss calculations show a prominent reduction from 12.92% to 2.69% when replacing single glazed windows to triple vacuum glazed windows. However, the space-Heating Energy cost savings can be more significant when the solid-wall insulation is improved to 2010 UK building regulations. Simulated results show a negligible space-Heating and cost savings with a house of double argon glazed windows compared to double glazed air filled windows. Solar gains do contribute in reducing the space-Heating load but during summer months it could cause overHeating and may be inconvenient to households and cooling is essential in such circumstances. Thus, the triple vacuum glazing, if manufactured at the mass production level with cost-effective airtight sealing materials and improved fabrication methods, is a great opportunity in reducing building Energy consumption and has a potential to increase window-to-wall area ratios without a risk of overHeating during summer months.

  • solar Energy gain and space Heating Energy supply analyses for solid wall dwelling retrofitted with the experimentally achievable u value of novel triple vacuum glazing
    Journal of Daylighting, 2017
    Co-Authors: Saim Memon, Philip C Eames
    Abstract:

    A considerable effort is devoted to devising retrofit solutions for reducing space-Heating Energy in the domestic sector. Existing UK solid-wall dwellings, which have both heritage values and historic fabric, are being improved but yet they tend to have meagre thermal performance, partly, due to the heat-loss through glazings. This paper takes comparative analyses approach to envisage space-Heating supply required in order to maintain thermal comfort temperatures and attainable solar Energy gains to households with the retrofit of an experimentally achievable thermal performance of the fabricated sample of triple vacuum glazing to a UK solid-wall dwelling. 3D dynamic thermal models (timely regimes of Heating, occupancy, ventilation and internal heat gains) of an externally-insulated solid-wall detached dwelling with a range of existing glazing types along with triple vacuum glazings are modelled. A dramatic decrease of space-Heating load and moderate increase of solar gains are resulted with the dwelling of newly achievable triple vacuum glazings (having centre-of-pane U-value of 0.33 Wm-2K-1) compared to conventional glazing types. The space-Heating annual cost of single glazed dwellings was minimised to 15.31% (≈USD 90.7) with the retrofit of triple-vacuum glazings. An influence of total heat-loss through the fabric of solid-wall dwelling was analysed with steady-state calculations which indicates a fall of 10.23% with triple vacuum glazings compared to single glazings.

  • a city scale degree day method to assess building space Heating Energy demands in strasbourg eurometropolis france
    Applied Energy, 2016
    Co-Authors: Manon Kohler, Nadege Blond, Alain Clappier
    Abstract:

    Abstract Efficient strategies are required to reduce space Heating Energy demands in buildings at city scale. Models taking into account the dynamic of the Urban Heat Island (UHI) phenomenon may be useful tools to help urban planners in this task. In this paper, we propose a new methodology to assess the Energy demands for space Heating in buildings at city scale: a degree-day method is applied, coupled with the use of a dynamic urban meteorological model that computes a building Energy budget. First, it is shown that the total building space Heating Energy demand at city scale, as simulated by the meteorological model, is quasi- linearly dependent on the daily mean city scale air temperature. The developed city-scale degree-day method applied to assess the space Heating Energy demands in Strasbourg Eurometropolis (France) is shown to be consistent with the estimates issued by local official Energy sources. A sensitivity analysis highlights the fact that while the Heating Energy demands are dependent on the building insulation performance and thermostat Heating temperatures, scenarios in which building Energy properties are changed do not significantly affect the UHI.
