Abstract:

This paper deals with the development of requirements for the energy-passive construction. The main emphasis is focused on a new categorization of passive houses into classes according to the Passivhaus Institute: the Passive House Classic, the Passive House Plus and the Passive House Premium. The requirement for annual specific heating demand is unchanged, maximally 15 kWh/(m2·a). A new evaluation system of Energy Passive Houses is based on renewable primary energy (PER). The aim of the paper is a description and evaluation of various classes of energy passive houses, including feasibility analysis and model examples.

Abstract:

The number of passive houses and zero-energy buildings being developed is increasing, as measures to reduce the rapidly increasing building energy consumption. While government building policies focus on energy savings, investors and the building market emphasize the initial investment cost. These conflicting perspectives obstruct the development of passive houses in the building market. In this study, a series of building energy analyses, including the effect of energy saving measures and economic information considering long-term economic benefit and incentives policy, will be presented. Analyses were performed on the energy-saving measures needed to improve the performance of single-family houses in Korea to that of the passive house standard, as well as the energy saving effect and increased cost. The application of energy saving measures for passive house implementation resulted in an additional cost of 1.85%–4.20% compared to the conventional reference house. In addition, the proposed passive house alternative shows a short payback period and life cycle cost (LCC) result, compared to a conventional building’s life cycle period. The possibility of passive house implementation is high, and developing the passive house is affordable for the investor or end user in Korea.

Abstract:

Passive House buildings with an annual energy demand of less than 15 kWh/m2a (i.e. kWh/m2 per annum) can help Canada and other countries achieve thermal comfort with minimum energy use and carbon footprint through meticulous design and selection of highly efficient building envelope elements and appliances. Shipping container based passive houses can reduce the cost of passive house construction and also promote recycling. In this paper, a passive house built using shipping containers, originally designed for Victoria, BC, Canada, is analyzed using Passive House Planning Package (PHPP) software in different climactic zones of Canada. The locations under consideration are: Halifax (Cool–Temperate), Toronto (Cold–Temperate), Edmonton (Cold), and Yellowknife (Arctic–Climate). This paper critically examines the energy demand changes in various climate zones and make necessary modifications to the design to achieve passive house energy performance requirements in selected climates. Results show that with modified designs shipping container passive houses can meet passive house requirements, except in the Arctic–Climate of Yellowknife.

Abstract:

The relevance of passive energy saving technologies in energy efficient low-rise construction in Russia is indicated. The definition of a passive house and its feature is given. Indicated that an attractive source of energy for heating the house is the energy of the sun. The definition of a solar house is given. The requirements for a solar passive house during its design are described: compact form of the house, optimal orientation of the house to the cardinal points, differentiation of glazing at home, passive use of solar energy, etc. It is noted that the most common system of passive heating of a house is to heat insulated glazed volume between nature and internal space of the house (vegetarian). The definition of a vegetarian is given, its design, features and advantages are described. Considered and analyzed various ways of heating solar houses from a vegetarian: a semi-direct, indirect, thermosiphon system with heating and circulation of warm air around the house. The classification of solar houses is discussed depending on the architectural solution for the placement of the vegetarian: a detached house with a vegetarian; a house with a vegetarian adjoining its main living space; a house located with a vegetarian under a common roof; a house with a vegetarian built into its living volume, a house with a “double shell”. The following types of vegetarians are listed: attached to an existing house, built into the house or being a “second shell” for the house. Practical recommendations for optimal work of a vegetarian are given: the need for special glazing (thermal mirror), protection from sunlight in the summer. The conclusion is made about the prospects of solar houses with a vegetarian due to the clear advantages of the passive heating system of the house and a high architectural and aesthetic level.

Abstract:

This essay proposes an inversion and productive complication of the familiar nomenclature of active and passive solar energy, as it pertains to architectural design methods and to solarity more generally: that is, to changes in economies, cultures, and ways of living in the present and future. I examine three houses central to the history of solar energy and its possible futures: the George O. Löf House (Denver, CO, 1957); the Douglass Kelbaough House (Princeton, NJ, 1974), and the Saskatchewan Conservation House (Regina, Saskatchewan, 1977) in order to assess the cultural and technical changes they elicited. At stake in reconsidering the distinction between active and passive solar energy is an attempt to understand how we experience simultaneously the resource conditions of our thermal interiors and the transformations of global climatic patterns. Which is to say, reconsidering active and passive in solar architecture (with heat storage as the hinge) also reconsiders the role of buildings in the production of the carbon zero future—less, at least relatively, as spaces of technological innovation, and more as spaces of social and species evolution. An active passive solar architecture aspires to lifestyles, habits, and expectations coming into line with the massive geophysical transformation of climate instability. By emphasizing the contingency of the built environment and of means of inhabitation, the solar house becomes a medium for epochal social change.

Abstract:

In recent years, ‘passive house’ is an increasingly well-known word, and has gained rapid popularity and application in Europe and other developed countries. Currently, residential passive house is growing at 8% annually in Europe. With its low energy consumption and ultra-high comfort, it is acclaimed as the most promising energy-saving substitute of conventional residences of this century. The passive houses in Hamburg Germany use 75% less energy than the normal low-energy buildings, more than 90% less than conventional German buildings [1]. As reported by the National Conference of Green Building Materials and German Passive House Technology held from 22nd to 25th April 2014, passive house will certainly become the mainstream building in the country in the next three to five years.

Abstract The term "passive house" refers to rigorous and voluntary standards for energy efficiency in a building, reducing its ecological footprint. There are many ways how to build a passive house successfully. These designs as well as construction techniques vary from ordinary timber constructions using packs of straw or constructions of clay. This paper aims to quantify environmental quality of external walls in a passive house, which are made of a timber frame, lightweight concrete blocks and sand-lime bricks in order to determine whether this constructional form provides improved environmental performance. Furthermore, this paper assesses potential benefit of energy savings at heating of houses in which their external walls are made of these three material alternatives. A two storey residential passive house, with floorage of 170.6 m2, was evaluated. Some measurements of air and surface temperatures were done as a calibration etalon for a method of simulation.

Abstract:

Passive housing is a combination of technological products which base on building energy saving concept, and it makes full use of solar energy, geothermal energy and other renewable energy to reduce the consumption of primary energy used in heating to 15 kw/h·m2·y, however, the energy consumption in low-energy house, which has equipped with various kinds of energy saving technologies, is about 30-75 kw/h·m2·y, thus, passive house has a better performance in energy saving than low-energy house. Energy saving technologies suitable for passive house and low-energy house in hot summer and cold winter area are proposed in this paper through introducing the contribution Germany has made and development of technology in passive housing, using its advanced technologies and practical experience ins passive house as reference and taking Chinese unique climate condition, building types and residents living habits into account.

Abstract:

A considerable amount of energy is being consumed for heating and cooling indoor environments in order to provide thermal comfort. For older buildings located in the southern parts of Iran, particularly in Bushehr, many climatic and passive design strategies are being used to provide indoor thermal comfort. This architecture and these elements have been developed in response to unfavorable weather conditions. The current study aimed to identify those passive elements and evaluate indoor thermal comfort in older houses. To achieve these objectives, passive elements in main houses located in the ancient urban structure were first identified. Then, a house in the coastal belt, Tabib’s house, and another house inside the ancient urban structure, Nozari’s house, were selected for the purpose of field measurement. The results revealed that the passive techniques used in these older houses significantly provide sufficient indoor thermal conditions. The mean measured predicted mean vote (PMV) of Tabib’s rooms was 0.88 and the mean measured PMV of Nozari’s rooms was 0.91, which were in an acceptable range. The measured predicted percentage of dissatisfied of rooms in both houses were lower than 10%. The main factor in creating indoor thermal comfort in these houses was the natural ventilation and its availability in the selected houses.

Existing European energy efficiency standards impose high requirements on yearly consumption of heat energy in buildings and on heat-protective qualities of cladding. One of the options of energy efficient buildings is the “passive house” with low energy consumption. As shown in this article, designs of “passive houses” have not always considered the requirements for preventing condensation in the cladding. Humidity conditions of the cladding of the “passive house” in the city Niš have been analyzed. It was found that for designing a heating system in the outer wall, with a specified outdoor air temperature, formation of condensation exists. To eliminate condensation we conceived vapor barrier layer technology from the inner surface of outer wall. Humidity conditions in the assembly of the vapor barrier layer have been calculated

Abstract:

Despite the economic and environmental benefits of passive houses, their market penetration has been low, which is partially due to misperceptions regarding their cost. This study examined the perceptions of building-related professionals and the general public regarding Korean passive houses to explore strategies for spurring passive house concepts and practices. The participants took an online survey on their interest in and reasons to reside in passive houses and their expected construction costs. The results from two separate groups of participants, including 162 professionals and 130 members of the general public, were analyzed using descriptive and inferential statistics. Both the professional and general public groups expressed a strong interest in passive houses because of the comfortable and healthy indoor environment, energy efficiency, cost savings, and sustainability that they provide. However, the expected construction costs of passive houses were perceived differently by the two groups: They were believed to be less expensive by the professionals and more expensive by the public respondents. This difference seems to result from their prior knowledge or experience regarding passive houses. Both groups were willing to pay more and assumed that the high expected costs were related to the construction products, systems, and labor costs of passive houses. The results showed that the lack of information or education on passive houses could be a major barrier to accessing passive houses, especially with the general public, while the cost could pose less of a barrier to the overall growth of the Korean passive house market. Further efforts by the government and industry are needed in order to provide more educational programs and to identify and manufacture more reasonably priced construction materials.

Abstract:

The Energy Performance of Buildings Directive (EPBD) has introduced the concept of Nearly Zero Energy Buildings (NZEB) specifying that by 31 December 2020 all new buildings must meet the nearly zero- energy standard, the Passive House standard has emerged as a key enabler for the Nearly Zero Energy Building standard. The combination of Passive House with renewables represents a suitable solution to move to low/zero carbon. The hypothesis in this study is that a certified passive house building with high levels of airtightness with a balanced mechanical ventilation with heat recovery (MVHR) should yield lower indoor radon concentrations. This article presents results and analysis of measured radon levels in a total of 97 certified passive house dwellings using CR-393 alpha track diffusion radon gas detectors. The results support the hypothesis that certified passive house buildings present lower radon levels. A striking observation to emerge from the data shows a difference in radon distribution between upstairs and downstairs when compared against regular housing. The study is a first for Ireland and the United Kingdom and it has relevance to a much wider context with the significant growth of the passive house standard globally.

Abstract:

Energy efficient building design aims to use passive design principles such as orientation, insulation, materials and surrounding area layout to minimise the need for active space heating or cooling. Implementation of the principles of energy efficient design in specifically low-cost houses delivered by government can have numerous benefits such as monetary savings, increased comfort and health indoor environments for homeowners and inhabitants. The project described here measured the indoor air quality of six energy efficient houses in two project areas as well as energy activity and potential benefits related to energy efficient house design. It was concluded that a small reduction in CO2 is achieved in an energy efficient house when compared with a conventional house. However, the reduction achieved is dependent on the type of fuel used for space heating. Overall, the energy efficient houses observed in the project were more comfortable and households spent less on space heating requirements than conventional houses. It is recommended that the principles of energy efficient design should be a minimum requirement in low-cost housing delivery.

With the rapid urban development of Lhasa in Tibet Autonomous Region, the traditional houses are losing gradually, while a great variety of city housing are springing up all over the city. Spatial patterns of city housing don’t blindly imitate commercial housing in most other cities in china, but have unique characteristics, such as building direction, functional layout, hole set, building construction and so on. The paper selects four types of Lhasa housing, rural traditional dwelling house, low-income apartment, detached house and multi-storey house, to analysis application of passive technology in detail and sums up three developing stages of passive technology in Lhasa area. On the basis, the paper discusses major factors about evolution of passive technology, that they are changes of spatial patterns, structure system and way of energy consumption. In the end, the paper puts forward some suggestions on the passive technology application in new city housing.

Abstract:

Passive building has been defined by Wolfgang Feist, Passivhaus Institut, as being the building that demand for heating must not be more than 15 kWh/m² year, and total consumption of primary energy should not be more than 120 kWh/m² year. In this paper we strive to study at the concept of ’passive house’ in the Finland. Using the Passive House Planning Package (PHPP) software 2007 calculate the heating requirements for such a House, depending on the latitude and climate conditions in the locality. For the study were selected 6 cities from Finland placed to different latitudes and climatic areas. To determine the possibility of implementing the concept ”passive House” must be determined: required heating, cooling demand and primary energy demand. In order to implement this concept should not exceed maximum limits.

Abstract The oil crisis, the measures taken because of global warming caused by greenhouse gas emissions, the ecological actions carried out globally and the technical progress in the fields of electronics, energy, IT and telecommunications have led to the emergence Passive House concepts in the construction sector, of Passive Solar Building (passive construction based on solar energy), of Net Zero-Energy Building NZEB, of Plus Energy Building, of nearly Zero Energy Building nZEB, of Low-Energy Building, of Green House, of Zero Carbon House, of Smart House, of Healthy buildings and other equivalents or derivatives. In this paper, these concepts will be cross-debated and the measures adopted at EU level and the influences exerted on the Romanian legislation on the field of civil and residential constructions will be presented. Based on a case study, a residential construction will be characterized, representative of the current housing stock, in order to assess the degree of compliance with the minimum requirements of a house with low energy consumption, imposed by Romanian legislation in the field.

Abstract:

The paper presents the preliminary planning of a demonstration pilot for exemplary renovation of an existing building (“Solar House 1 – Campina”) towards nZEB level using Passive House principles and technologies. The “Solar House” was one of the lighthouses of solar energy developments in the ‘80s in Romania, being built in 1977-1978 in Campina (Centre-South Romania) and represented an experimental building using innovative solar technologies for DHW preparation, active and passive space heating. The decision of transforming the existing building in a demonstration pilot nZEB with green materials was taken and the feasibility study is currently underway. The pilot aims to analyse and test, the cost effectiveness of Passive House (PH) technologies integration in a deep renovation process with the view to achieve the fixed nZEB levels, as an exemplary case study demonstrating the benefits and feasibility of applying PH principles and energy performance evaluation in real context. Both approaches of applying the renovation standard EnerPHit and targeting Passive House criteria are discussed together with the nZEB targets, while the analysis of technical (energy performance) and economic (total costs) feasibility is presented. The proposed building will act as a training and consultancy centre in Campina - created as a model for achieving greater energy efficiency and environmental responsibility in Romania.

Abstract:

The paper describes one of the energy-efficient building concepts – a passive house. In the course of the work, a multifamily residential house was simulated in order to determine its constructive and spatial parameters that would ensure a passive house with energy efficiency in compliance with the fixed standards. The climatic data of the Latvian capital, Riga, were applied to this building simulation. Initially, an optimal orientation and maximum theoretical insulation of the building were chosen. At the second stage, the external factors – the shade caused by the surrounding buildings and effect of the building orientation dictated by the existing urban conditions – were studied based on the previously achieved energy efficiency rating. The results evidenced that the layout of window apertures and change of orientation, as well as shading caused by the surrounding buildings, plaid a significant role in the rating of the building energy efficiency nonetheless it did not interfere with achieving the passive house standards.

Selecting a residence of eastern region of Qinghai province as the research object, the author conducted the test on indoor temperature and relative humidity in winter. Based on the analysis of test data, quantitative assessment was made on residential thermal environment in different passive energy saving measures. The results showed that houses with additional sunspaces or the houses with passive technology can still reach the basic requirement of human thermal comfort even in the absence of heating measures. In the daytime, indoor and outdoor temperature could reach to 21.4 °C. According to the test results, passive energy saving measures should be adopted in house construction in order to adapt to the local climate. This way can effectively improve the local building indoor thermal environment in winter.

Abstract:

Bioclimatic architecture strategies and solar active systems contribute strongly to the reduction of building energy demand and achieving thermal comfort for its occupants over the whole year. This paper deals with the study of the energy performance improvement of a pilot bioclimatic house located in Algiers (Algeria). First, a series of experimental measures are conducted during cold period to show the effect of passive and active solar gains on the improvement of the indoor air temperature of the house. Then, a dynamic model of a solar heating system coupled with a bioclimatic house has been developed using TRNSYS software and validated with experimental data. The validated model has been used to establish the energy balance of the pilot bioclimatic house without solar heating system and to compare them to those of a conventional house. Finally, the improvement of the energy balance of the pilot bioclimatic house has been done by passive and active ways. The passive one includes the increase of south facing windows size and the use of night cooling with the use of shading device in summer. The active one consists of the integration of a solar heating system. Furthermore, an environmental study has been performed. The experimental results show that the energy requirements of a pilot bioclimatic house are very low which is suitable for the use of solar heating system in building. The simulation results show that the application of bioclimatic strategies is a better way to provide thermal comfort in summer and decrease the space heating energy demand of the house with 48.70%. The active solar system will cover 67.74% of the energy demand for heating of the house. These energy savings generate a significant reduction in CO2 emissions. Practical application: This work will enable engineers and designers of modern buildings of buildings in a Mediterranean climate to improve building energy efficiency and reduce CO2 emissions by a conjunction of different passive heating and cooling techniques such as insulation, thermal mass, window shades, night ventilation, and the solar heating system. The paper provides designers an effective strategy in terms of energy savings and indoor thermal comfort while reducing CO2 emissions.

Abstract:

Purpose This paper aims to understand the effect of different foundation designs of passive house on the resultant thermal bridges, at the junction between a wall and a slab on grade. Design/methodology/approach The linear thermal transmittances of some newly developed foundations of passive house are determined. The investigated foundation designs are L-element, U-element and foundation with foam glass technique. Findings It is found that the special design of passive house foundation can considerably influence the heat flow through thermal bridges. In this context, it is proposed a new foundation design of passive house, which has relatively low heat loss through thermal bridges. The results are compared with the “default” ISO values used to evaluate the effect of thermal bridges in typical buildings. It is found that there is large difference between the calculated linear thermal transmittances at the investigated foundations of passive house as compared to typical buildings. Practical implications The results can hopefully be used to improve the energy efficiency of the passive house. Social implications Sustainable solution of buildings. Originality/value A new foundation design of passive house is suggested to reduce heat loss through thermal bridges.

Abstract:

This article presents the results of experimental research on energy consumption of a prefabricated lightweight passive house located in the south of Poland. The key design parameters of the building were as follows: orientation maximizing heat gains from solar radiation, high thermal insulation of partitions, heat provided by ground source heat pump, and mechanical ventilation system with the heat exchanger. The measurements were performed in normal operating conditions in an inhabited building, throughout the years 2011–2019. For the year 2012, the article also presents the detailed structure of electricity used for particular devices. The objective of the research was to verify whether, in the long term, the building fulfils the energy consumption requirements for passive buildings. The measurements showed that energy consumption for heating was 50% lower than the value required from passive buildings. However, primary energy consumption for the entire building was exceeded already in the second year of research. This was caused by two factors: human behaviors and the type of primary energy source. The research concludes that the maintenance of passive house standard is vulnerable to human impact and difficult in the case of power source characterized by high index of expenditure on non-renewable primary energy. The article also presents recommendations on how to restore the passive house standard in the building.

Abstract:

Passive building design reduces a building’s energy consumption through mainly non-mechanical design strategies. The Passive House (or Passivhaus) Standard certifies such buildings that comply with its strict energy performance criteria. Achieving the Standard is very challenging for dwellings in extreme climates. There is limited knowledge of the Standard’s potential in Arctic regions, particularly the High Arctic. Through a review of the literature and energy modelling of a hypothetical dwelling, the challenges in achieving the Standard in Longyearbyen (78°N), Norway are investigated. Very low temperatures and 112 days without daylight create a high heating demand. Whereas previous studies measured actual building performances or used simple calculations, the findings in this investigation show the limitations of individual design parameters and technical limits of the building envelope. In theory the Standard can be achieved in Longyearbyen; however, the potential in practice is low due to the very tight margins in the heating criteria. The results show the significant impact of applying contextual (climatic) adjustments to the boundary conditions of the Standard. The investigation could contribute to a discussion on modifying the Passive House Standard for dwellings in the High Arctic and improving building design for the region. Practical application: Current knowledge regarding energy efficient building performance in Arctic climates is limited, while the urgency for improved efficiencies is extremely high. The modelling in this work shows the valuable impact of contextual adjustments to the Passive House boundary conditions; the impact of individual design parameters; and the potential for significant energy savings through adopting passive house principles for dwelling design in Longyearbyen or similar climates. This investigation could encourage new policy making, additional research and the development of an optimized Passive House Standard that considers High Arctic climate conditions, thus encouraging new energy efficient building construction in cold climates.

Abstract:

A significant portion of energy consumed in buildings is due to energy usage by heating, ventilation, and air conditioning systems. Free cooling is a good option for energy savings in the systems. In recent years, scientists, engineers, and architects designed successful and innovative buildings which use passive cooling techniques, such as natural ventilation. The house studied in the present work, is a pilot project undertaken jointly by the Centre for Development of Renewable Energies (CDER) and the National Centre for Studies and Research of the integrated building (CNERIB) in the framework of the MED-ENEC project (Mediterranean Energy Efficiency in Construction structure). The house under consideration has a surface area of 65 m2 and is located in the region of Algiers which characterized by a Mediterranean climate with relatively mild winters and a hot and humid summer. The aim of this work is to study the thermal comfort inside the house in summer without air conditioning systems, only ventilation is considered. The aim of this work is to study the effect of natural ventilation on both thermal and hygrometric comfort inside the house during the summer period. Numerical simulation is made using the TRNSYS software and the results obtained are in good agreement with measured values. The prototype home is designed in a way that natural ventilation allows thermal comfort which induced energy saving from air conditioning. The mean temperature measured in the interior of the house is 26?C. The relative humidity reaches about 70% in August. Thermal comfort is related to relative humidity that are the essential parameters of the feeling of comfort. Humidity is an important parameter in thermal comfort, it is why we can conclude that we have reached a relatively good hygrothermal comfort.

Abstract:

Within the European framework, the passive house has become an essential constructive solution in terms of building efficiency and CO2 reduction. However, the main approaches have been focused on post-occupancy surveys, measurements of actual energy consumption, life-cycle analyses in dynamic conditions, using simulation, and the estimation of the thermal comfort. Few studies have assessed the in situ performance of the building fabric of passive houses. Hence, this paper explores the applicability of non-destructive techniques—heat flux meter (HFM) and quantitative infrared thermography (QIRT)—for assessing the gap between the predicted and actual thermal transmittance of passive house façades under steady-state conditions in the Mediterranean climate. Firstly, the suitability of in situ non-destructive techniques was checked in an experimental mock-up, and, subsequently, a detached house was tested in the real built environment. The findings revealed that both Non-Destructive Testing (NDT) techniques allow for the quantification of the gap between the design and the actual façades U-value of a new passive house before its operational stage. QIRT was faster than the HFM technique, although the latter was more accurate. The results will help practitioners to choose the most appropriate method based on environmental conditions, execution of the method, and data analysis.
