Abstract In our days, energy issues belong to the most important problems facing the Earth and the solution may be expected partly from decreasing the amount of the energy used and partly from the increased utilisation of renewable energy resources. A substantial part of energy consumption is related to buildings and includes, inter alia, the use for cooling/heating, lighting and cooking purposes. In the view of the above, special attention has been paid to minimising the energy consumption of buildings since the late 1980s. Within the framework of that, the passive house was created, a building in which the thermal comfort can be achieved solely by postheating or postcooling of the fresh air mass without a need for recirculated air. The aim of the paper is to study the changes in the construction of passive houses over time. In addition, the differences between the geographical locations and the observable peculiarities with regard to the individual building types are also presented.

Low Energy Buildings

Passivhaus or Passive House buildings are low-energy buildings in which the design is driven by quality and comfort, hence achieving acceptable levels of comfort through post-heating or post-cooling of fresh air. Additionally, Passivhaus building design follows the Passivhaus design criteria, as described in the Passive House Planning Package (PHPP). This article aims to introduce the Passivhaus background, development, and basic design principles. Finally, it also presents a brief description of the performance of Passivhaus buildings.

Abstract Background and Aims The environmental impact of dialysis is now being largely recognized. It requires from the nephrology community to actively explore novel environmentally responsible health-care practices. Among them, conception of energy-efficient facilities may be an important prerequisite for improving the environmental impact of dialysis. The Passive House concept is an internationally recognised, performance-based energy standard in construction which so far has been rarely applied to medical facilities and never to dialysis centres. We report our experience with the first passive-house certified dialysis facility in Europe. Method The Passive House concept is a sustainable construction standard for nearly zero energy buildings (the Resolution of the European Parliament of 31/01/2008 has called for its implementation by all member states by 2021). Principles and design tools of the Passive House concept are freely available for all architects. The concept combines a particularly high level of insulation with a specific system of ventilation. Geothermal energy and energy from inside the building such as the body heat from the residents or solar heat entering the building are the main energy sources. Passive House buildings allow for heating and cooling related energy savings of up to 90% compared with typical building stock and over 75% compared with average new buildings. Results The François Berthoux Center (www.artic42.fr) is a 4 400 m2 dialysis facility operated by 40 health care agents and providing care to 135 patients. It was designed following the Passive-House standard, applied for the first time to such a medical building. Several adjustments specific to the dialysis activity were necessary. The most unexpected aspect was the importance of hemodialysis machines as an energy source. Thorough thermal evaluation showed that the heat provided by different type of hemodialysis machines was systematically superior to the energy mandatory during the coldest day of the year (>10 W/m2). In practice, the center turned out to be fully operational with no external source of heating. The downside was that the geothermal pump system was not sufficient to fully regulate temperatures during the warmest period of the year. Optimal cooling was achieved by the addition of conventional AC systems in the hemodialysis rooms. Overall, as compared to a similar center, energy savings provided by the The François Berthoux Center were substantially less than what is expected from a conventional Passive House building but were over 50%. The extra-cost of the construction was estimated to 3 to 5%. Conclusion In conclusion, the concept of eco-friendly building should extend to dialysis facilities. Application of the Passive House Standard in the context of hemodialysis requires to take into account some specificities that can impact the global environmental performance of the building. However, the net result is clearly in favor of such a construction, which is both affordable and sustainable.

Wall System

Achieving Passive House certification requires super insulation which can significantly raise the embodied energy and carbon footprint of a project, effectively front-end loading the climate impact, especially where petrochemical foam-based products are used. This research sought to evaluate the use of straw bales - a low embodied energy, carbon sequestering agricultural by-product - to achieve PHIUS+2015 certification. A straw bale wall system was adapted to a single-family detached reference house designed to meet the Passive House standard. The wall system was evaluated for applicability across three Western Canadian cities using WUFI Passive energy simulation software to evaluate compliance; thermal bridging and hygrothermal performance were also evaluated. It was found that the proposed straw bale wall assembly satisfied the PHIUS+ 2015 requirements in all three locations - Saskatoon, Calgary, and Kelowna - with only minor changes required to the reference house design. The annual heating demand and peak heating load, the two targets most sensitive to design changes, were, respectively, 4% and 8.6% below the target in Saskatoon, 63.1% and 21.3% below in Calgary, and 63.1% and 32.6% below in Kelowna. The research also revealed that maintaining a high degree of air tightness is essential for satisfying the requirements. Overall, this research demonstrates that straw bales can be a beneficial component in creating high performance enclosures without exacting a large embodied carbon footprint.

Detached accessory dwelling units are a building typology that, when built to passive design standards, can help reduce GHG emissions while addressing the socioeconomic pressures facing many housing markets. Energy performance metrics like those used in passive design standards are based on per unit of floor area and lead to a size-bias against smaller housing typologies. A life cycle assessment of cost-optimal passive house sizes ranging from 230 m² (2,500 ft²) to 30 m² (300 ft²) is performed to understand their total life cycle energy use and GHG emissions implications. Additionally, an analysis using BEopt examines operational energy use for 10 cost-optimal passive house sizes ranging from 230 m² (2,500 ft²) to 30 m² (300 ft²) across all 17 climate zones and examines how cost-optimal passive design changes with house size. The results show that per-occupant energy use and GHG emissions are similar or better for small house sizes and that cost-optimal passive design does not change significantly with house size.

Abstract This paper outlines for construction specialists the concept of "passive house", presenting the actual status of research and breakthroughs within this field within the country and abroad but also the directives of the European Council and European Parliament regarding this concept. Last, but certainly not least, it showcases some of the flaws of the European Directive regarding passive houses, because it fails to bring forth viable solutions for a number of dire issues.

This research compared and analyzed where the Ontario Building Code rates in the low-rise, residential sector in terms of its: in comparison to Denmark, Germany and the Passive House Standard. This was analyzed to see how Ontario compared against other world renowned energy efficient regulations and where or if there was room for improvement. For this, HOT2000 and THERM were utilized on all four of the reference standards, where both of these programs were managed in a way to compare the results of ‘typical’ building envelopes and the current regulation from each of the standards. These results were then able to provide a whole home’s heating and air conditioning energy use in the Greater Toronto Area climate. Overall, the results illustrated Ontario homes consume the most energy for both typically constructed homes and homes utilizing the minimum requirements. In addition to this, Ontario also had the least performing building envelope connection details. In total, the Passive House performed at the highest level followed by Germany, Denmark and then Ontario.
