The demands for both thermal comfort and reduced energy consumption in buildings have become a major driving force for the increased use of advanced building automation and control systems (BACS). In the on-going development of Zero Emission Buildings (ZEBs), it seems to be a common understanding that such systems are needed in order to save energy and reach the zero emission goals, and that energy consumption for their operation is negligible compared to the building needs and the energy saving potential BACS causes. However, sensors and actuators in automation and control systems require electricity to operate, and both the environmental…

We are currently witnessing in the Norwegian building sector (and elsewhere) the transition from isolated and heterogeneous sustainable building projects carried out in protected niches (e.g pilot projects) to more sustainable buildings becoming mainstream. According to scholars studying sustainable transitions this is the moment in which a dominant design catches on, replacing and displacing other more or less sustainable alternatives. Within this process, in the Norwegian case, the principles behind the passive house play a salient role. In fact, only recently a government white paper has called for "passive house levels" to become part of the building code by 2015.…

Solar Radiation Glazing Factors for Windows Panes, Glass structures and Electrochromic Windows in Buildings - Measurement and Calculation
Authors:
Publication Year:

Authors:
Publication Year:
2013
Window panes, glass structures and electrochromic windows in buildings may be characterized by a number of solar radiation glazing factors, i.e. ultraviolet solar transmittance, visible solar transmittance, solar transmittance, solar material protection factor, solar skin protection factor, external visible solar reflectance, internal visible solar reflectance, solar reflectance, solar absorbance, emissivity, solar factor and colour rendering factor. Comparison of these solar quantities for different glass fabrications enables one to evaluate and thus select the most appropriate glass material or system for the specific buildings and applications. Measurements and calculations were carried out on various glass materials, including three electrochromic window devices,…

Environmental perspective on two glazing typologies
Authors:
Publication Year:
2013
Authors:
Publication Year:
2013
Stricter energy regulations for energy use in buildings require new construction to be equipped with increasingly thicker insulation layers and minimal surfaces for glazing in cold climates. In recent years a new type of window has been proposed as a way to overcome the notoriously low thermal performance of transparent surfaces. In order to reach such performances, this glazing type has been equipped with monolithic aerogel as the glass-pane filling. The scope of this study is a comprehensive analysis of greenhouse gas emissions from the partial substitution of typical triple-glazing-with-argon units with double-glazing-with-monolithic-aerogel units in residential building upgrades. A social…

The main definition of a Powerhouse is a building that shall produce at least the same amount of energy from on-site renewables as the energy used during construction, manufacturering of materials, renovation, demolition and operation exclusive energy used during manufacturering of equipment such as PCs, coffee machines etc. In addition the exported energy shall in average not have less quality than the imported energy. This implies that produced and exported electricity can offset corresponding amount of imported energy for both electricity and thermal purposes, while produced and exported thermal energy cannot offset imported electricity. The building shall also as a…

Post-Occupancy Evaluation of Low-Energy and Passive House Apartments in the Løvåshagen Cooperative - Occupant Behavior and Satisfaction

Authors:
Publication Year:
2013
Experience with low-energy and passive house buildings forms the basis for the further development of zero-emission buildings. A post-occupancy evaluation of the Løvåshagen cooperative is therefore conducted by means of user surveys and measurement of indoor climate parameters, energy use and window opening time. The goal of the post-occupancy evaluation is to obtain information about how occupants use and experience low-energy and passive house dwellings, especially with regard to heating and ventilation. In addition, the impact of user behavior on the indoor climate and energy use will be assessed. In this paper, the results of the user survey regarding user…

Greenhouse gas analysis of insulation options in residential energy retrofitting

Authors:
Publication Year:

In the pursuit of stricter energy standards for buildings to reduce their share of energy use, the use of highly efficient insulation materials like aerogel and vacuum insulation has opened a path towards lighter construction in energy retrofitting, whereas commercially available materials, such as EPS and mineral wool, result in massive wall solutions. However, these new materials are notoriously energy intensive in production, resulting in high levels of embodied energy and emissions. This work describes a comprehensive greenhouse gas analysis of the use of different insulation materials applied to residential building upgrades to passive house standard. It estimates the potential…

Experimental Examination of the Thermal Transmittance of High Performance Window Frames and Comparison with Numerical Simulations
Authors:
Publication Year:

Publication Year:
2010
While window frames typically represent 20%"30% of the overall window area, their impact on the total window heat transfer rates may be much larger. This effect is even greater in low-conductance (highly insulating) windows that incorporate very low conductance glazings. Developing low-conductance window frames requires accurate simulation tools for product research and development. The Passivhaus Institute in Germany states that windows (glazing and frames, combined) should have U-factors not exceeding 0.80 W/(m² K). This has created a niche market for highly insulating frames, with frame U-factors typically around 0.7-1.0 W/ (m² K). The U-factors reported are often based on numerical…
