Full textAbstract:
Air pollution emissions are released from both natural and anthropogenic sources. During the environment pollution researching and monitoring the special attention should be paid to the construction operations, since during the construction processes many pollutants are released, especially fine dust particles, which are harmful to the health of construction workers and the population living near the construction site. The construction of any object in urban terrain has bad influence not only on the nearby buildings and city infrastructure, but on the existing environment of urban areas. The identification of the important pollution sources that contribute to ambient concentrations of pollutants is essential for developing an effective air quality management plan during building construction. Particular attention should be paid to emissions of fine particles during technological processes of construction with a special degree of dust emission. Control and regulation of the dynamic state of dispersed systems released during technological construction processes using a number of protective measures will reduce emissions of pollutants into the air. The objects of this research were the construction site and residential buildings of a large residential complex «Ekaterininskiy» located in Rostov-on-Don. The obtained measurement data as a result of this type of environmental monitoring showed the level of atmospheric air pollution from the construction industry using the example of the construction of the residential complex “Ekaterininskiy” in Rostov-onDon. After analyzing the situation with dust pollution the protective measures were suggested.

The article describes the technology of deformation geodetic monitoring of a multi-storey res-idential building during construction. The description of the main stages of work: the choice of the location of the reference frames and the assessment of their stability, the placement of deformation marks on the observed structure, the location of leveling moves along deformation marks, the im-plementation of several cycles of geodetic measurements and the determination of deformation marks observed by their results The analysis of the obtained results has been performed, which suggests that at the time of the measurements, the observed deformation processes are predictable. Recommendations on improve-ment of the measuring measures complex are given, and the possibility of forecasting is considered, and the predicted values of the sediment deformation marks are calculated, which practically coin-cide with the actual values obtained in the next observation cycle.

Full textAbstract:
Building materials, due to their mass and energy-consuming production processes, drastically increase the embodied energy of construction. This study assesses circularity processes for the construction industry with a life cycle assessment (LCA) of a case study located in a large cosmopolitan city. The research concludes that a significant decrease in environmental impacts results from a shift to recycled materials in the construction phase, as well as from changing the landfill disposal method to recycling. In particular, it was found that the use of recycled building materials (such as recycled cement, metal, concrete, or glass) during the construction phase and recycling disposal methods lead to an overall decrease of impact up to 65%. This work also underlines the importance of circularity in renewable energy production systems. In both wind and solar systems, most of the environmental impact caused during the production phase are paid back during the second year of their life due to the energy gains of the renewable energy system. However, the recovery of metal depletion requires 667 years. This result provides evidence of the emerging need for integrating circular processes regarding recycling and reusing materials in construction and also in the energy-generating sector.

Full textAbstract:
The construction industry is plagued by long cycle times caused by variability in the supply chain. Variations or undesirable situations are the result of factors such as non-standard practices, work site accidents, inclement weather conditions and faults in design. This paper uses a new approach for modelling variability in construction by linking relative variability indicators to processes. Mass homebuilding sector was chosen as the scope of the analysis because data is readily available. Numerous simulation experiments were designed by varying size of capacity buffers in front of trade contractors, availability of trade contractors, and level of variability in homebuilding processes. The measurements were shown to lead to an accurate determination of relationships between these factors and production parameters. The variability indicator was found to dramatically affect the tangible performance measures such as home completion rates. This study provides for future analysis of the production homebuilding sector, which may lead to improvements in performance and a faster product delivery to homebuyers.

As we enter 21st century, the environmental problem is increasingly prominent. Chinese urban residence construction stands in the transition period of sustainable development. How to realize low energy consumption, long service life and high quality of residence becomes a subject to be solved in Chinese residence construction in new era. For China's traditional residential design and construction method formed as a linear process and single data feedback as well as great loss of information in design, the residential quality and properties have not only been unimproved, but have also led to relatively more time and costs spent. This paper introduces a design concept of whole life cycle and points out the traditional design concept and processes of the residence construction must be charged in order to realize its sustainable development. According to the design concept of the whole life cycle, this paper puts forward the residence design principle based on whole life cycle and institutes the residence design processes based on whole life cycle.

Full textAbstract:
Noise pollution from construction sites has become a major problem for major cities with the continued rapid development as well as redevelopment of cities. These construction sites, in particular for new subway systems, are often near to residential and commercial buildings. A better understanding and characterization of noise profiles will be required for project management and planning as well as environmental impact assessment. In this study, instead of using the typical type 1 sound level meters for the measurement of noise profiles emitted from construction equipment and processes commonly done in construction industry, we attempt to characterize the noise profiles of common construction equipment at their respective noise source using an Acoustic Array or Acoustic Camera. The study also highlighted the significant presence of low-frequency noise at construction sites for some construction equipment and processes. This may have some implications for the design of noise barriers at construction sites.

Purpose Compared to the manufacturing industry, Lean Six Sigma (LSS) lacks a clear methodology for its application in the tertiary service. One reason is the difficulties to assess information flow compared to physical flow. Indeed, the use of information flow as a process entry in the LSS method is not well investigated, mainly due to the difficulties in collecting adequate and sufficient data. The purpose of this research study is to investigate the application of LSS in the tertiary service, in particular, real estate development. Design/methodology/approach The paper is based on an action research methodology where LSS methodology is applied to solve client-dissatisfaction issue. One of its main causes is found to be the late delivery time. The work describes how the method was applied. Findings LSS is an adequate approach for making well-thought-out improvement in real estate development. Practical implications The work provides an implementation of LSS in real estate development. It also gives new insights into the LSS application in the tertiary service. The work also suggests practical recommendations and solutions to address the main challenges faced by real estate development. Originality/value Construction is governed by many processes that are difficult to identify and, even more, to assess. LSS helps identifying those which create real value for the client.

Full textAbstract:
The research problem undertaken in the study is the occurrence of dispersed and concentrated built-up (in particular residential) area patterns caused by suburbanisation processes in a large urban agglomeration, on the example of the Warsaw metropolitan area. The research concerned the period after 1989, when the political and economic transformation in Poland began. The historical and contemporary socio-economic conditions of suburbanization and urban sprawl are described, which have the features of a spontaneous, chaotic dispersion, quite different than in Western countries. It is partly to blame for faulty spatial planning. The succession of urban development into rural areas is subordinated to the factors of the construction market. In the empirical part of the analysis, topographic data on all buildings in the urban agglomeration and databases on land use derived from satellite images were used to investigate settlement changes. A multidimensional study was carried out relating to various spatial scales, types of spatial relations and territorial units. Measures of spatial concentration of point patterns as well as landscape metrics were used for this purpose. The indicators used were subject to critical methodological evaluation afterwards. The study was performed in several temporal cross-sections. The locations of new development in agricultural, forest and wasteland areas have been identified. Finally, recommendations for the implementation of appropriate spatial policy and improvement of the spatial order in the Warsaw agglomeration were formulated

Full textAbstract:
This chapter examines tall residential buildings using engineered wood products (EWPs) in Finland. As specified in the National Building Code of Finland, ‘tall wooden building’ is defined as a structure with more than 8-story. Currently, there are two wooden residential buildings, 14-story Lighthouse Joensuu (2019) with laminated veneer lumber (LVL) structure and 13-story HOAS Tuuliniitty (under construction) with cross laminated timber (CLT) structure, that fit the definition above. This study analyses the phenomena associated with the design and implementation processes of these remarkable buildings, the starting points for the projects as well as the prospects of tall wooden housing in Finland through the case study method and interviews with the key actors in the projects. These cases are mapped with extremely detailed information, comprising a valuable source both for designers, engineers as well as developers. As a result, the current state-of-the-art and the critical factors influencing the design and implementation of these challenging sustainable projects in Finland have been identified. It is believed that this chapter will aid and direct key stakeholders in the construction industry in the sound planning and development of tall wooden residential projects in Finland.

Full textAbstract:
The paradigm shift towards waste reduction in the construction industry has produced revolutionary techniques in assessing and mitigating waste during the construction lifecycle. Unmanned Aerial Vehicle (UAV) technology presents potentials in real-time construction waste management for informed decision-making processes for site managers. Due to the dynamic and complex construction work environment, material and equipment, labour and management policies are subjected to latent and identified hazards. Therefore, this chapter focuses on the real time impact of construction waste. UAV technology was adopted. UAV flight mission and deployment time were designed to meet target requirements and snapshot checklist. Data images were captured from an 11-storey residential building and analysed for conformity to construction waste and safety requirements. The prevalence of exposed material and equipment, low labour awareness, and need for policy shift to circular economy was predominant. Further studies can explore multiple construction monitoring and other category of construction works.

Balancing the housing function in large cities. Purpose: The aim of the study is to assess spatial cohesion of suburban areas in terms of balancing the volume of housing functions and accompanying functions in the gminas (communes) of the Poznań agglomeration in the years 2012–2016, based on the analysis of the functions of buildings under construction. Design/methodology/approach: The author has conducted the following tasks: reviewing the literature on suburbanisation processes, in particular in the Poznań agglomeration; performing a statistical analysis on the basis of data from Statistics Poland (GUS); assessing the volume of construction activity performing various functions in the area of the Poznań agglomeration; indicating the main function of newly constructed buildings and analysing measurable characteristics depicting the scale of construction activity, including the number and usable floor area of buildings or the number of dwellings (in the case of the residential function); assessing the relativised characteristics relating to the area and population numbers. Findings: The processes of suburbanisation and the implementation of the residential function are spatially diversified in the Poznań agglomeration. The balance of the housing and supplementary functions differs in individual gminas of the area under analysis. The relation between the usable area of newly completed buildings intended for non-residential purposes (supplementary functions) to the usable area of newly completed buildings intended for residential purposes in the Poznań agglomeration reflected the situation that took place all around Poland. The balance of the residential and supplementary functions depends on the following factors: the state of spatial development in the past (e.g. the presence of land that could be transformed for the needs of a new function), the existence of environmental or administrative development barriers (e.g. marshy ground, military training ground), the current scale of the occurrence of individual functions (e.g. the degree of market saturation with commercial space) or their location on important transport routes. Originality and value: In the face of the inevitability of the development processes, changing the spatial structure of areas surrounding large cities is a challenge for present and future generations, and in particular for local authorities. Even today, we may observe spatial changes affecting rural and rural-urban gminas neighbouring large cities. Under the pressure of the suburbanisation process, the developed residential function in such gminas forces them to take care of other functions that rural areas (so far unprepared to provide most of the functions characteristic of cities) perform or will perform in the future.

Full textAbstract:
The aim of the article is to investigate the historical development of the architectural form of the megaron and identify the factors that contributed to the rethinking of its functional features: from a purely utilitarian to a cult purpose. The research methodology is based on an integrated approach and relies on the analytical (when analyzing art history and cultural literature on the subject of research), historical (when clarifying the stages of the formation of the megaron as a form of cult architecture) and conceptual (when analyzing the influence of the processes of aestheticization, ethization and sacralization on the formation of the megaron). The scientific novelty of the article is to identify the factors that contributed to the rethinking of its functional features: from a purely utilitarian to a cult purpose. The results. The evolution of the architectural form of the megaron – from adobe houses with a place for a fire and an overnight stay in the stone building itself, certifying the fact of aestheticization (I invoke this form in the historical development of mankind). In particular, the example of the Temple of Hera in Olympia shows the imitation of wooden structures in stone architecture. This fact historically testifies to the peculiarities of the formation of the Dorian architectural order in Greek culture. Reconsideration of the megaron as a residential building, and as a result of a monumental temple, an altar, is a process of etization and sacralization. This also applies to the columns, in particular, which are first erected out of technological necessity, and over time serve as a necessary aesthetic attribute of the architectural form of the megaron. If clay and wooden buildings were erected mainly for the life of people, then the stone megaron, according to the technology of processing raw materials and the principles of construction, were many times more complicated – they became a kind of monuments and temples, often of a purely religious purpose. The reason for this is not only an understanding of the strength and endurance of raw materials, because if people created structures of stone only so that the latter would withstand as long as possible, then these amazing artifacts would not be so exquisitely and filigree decorated. The practical significance. Key points and the research results can be useful for studies of the processes of cultural development of mankind, in particular, consideration of the history of architecture and sculpture, the processes of aesthetization, ethization and sacralization. Moreover, the article can be used for educational disciplines of culturological and art history in Ukraine and abroad.

Full textAbstract:
The use of 4D Building Information Models (BIM) for planning construction site logistics has increased in recent years. However, most 4D BIM studies have focused on transformation tasks, neglecting flow activities. Hence, the objective of this paper is to evaluate the use of 4D models for flow simulation at operational level, aiming to reduce transportation waste. A field study was conducted on a residential housing project in Brazil. The study included three stages: data collection; 4D BIM simulation; and outcome analysis. Data collection during the site visits aimed to map the physical flows involved in the construction processes studied. Transportation waste were identified, constructive details were collected and time studies were conducted. This information was used for the 4D model development. During the outcome analysis the 4D BIM was presented and discussed in a seminar to the managers and in a workshop to the workers. After that, the model was implemented in the field and the contributions of the 4D BIM for transportation waste reduction were identified. The results highlighted the need to plan transportation activities in constructions site. The use of the simulation developed contributes to the reduction of transportation waste consequences, such as: unsafe working conditions, new transportation activities, and longer distances.

Solar thermal energy is an alternative to provide heat for low-enthalpy processes at commercial and residential sectors in communities with energy sources scarcity. The present work is focused in the experimental performance analysis of a parabolic trough collector (PTC) designed and manufactured to minimize construction costs by setting the best parabolic profile and rim angle to improve thermal efficiency through enhancing light reflection in its parabolic surface, compound by conventional flat mirrors. The design considers an uncovered copper alloy receiver aligned with the focus of the reflective surface supported on a light metal structure. Sunlight collection area was defined at 1.2 m2 to allow installation of serial or parallel modular arrangements at reduced spaces like a building rooftop, the concentration ratio for this PTC is close to 33. This device was designed to use water as heat transfer fluid (HTF) and to be operated under environmental conditions of the city of Barranquilla, Efficiency curves were obtained based on experimental tests conducted with multiple HTF flow rate and varying reflecting surface slope for one PTC, obtaining a peak efficiency of 48 % and a without a tracking system. This device can be manufactured with a cost close to 80 USD/m2.

Full textAbstract:
Quoting from the inscription into the Intangible Cultural Heritage List (2018), the art of dry-stone walling concerns “the know-how” related to making stone constructions that explains the interest towards the product process as well as the product itself. The protection of the ability in stones selection and their placement, without mortar or dry soil at most, has moved the attention from walls to walling too. As a result, the idea of authenticity should be rediscussed to preserve not only some existing monuments and amazing landscape, but a living heritage and a sustainable land use. A risk occurs in some coastal areas, both maritime or front lake, and in the valleys, of the Alps or the Apennines. These places are the most sensitive to residential and receptive exploitation; as a result, an aesthetic landscape perception is taking advantage against its structural conception and the authentic art construction for dwelling (buildings), farming (terraced arrangements) or husbandry (cow-walls). The awareness of the role of dry building for the consolidation of the slopes, the protection of the mountain and the harmonious relationship between environments and species the inscription would preserve, is misunderstood. In Italy some evident ambiguities are occurring into practice and local behaviours. Although the inscription has invited preservation program, the governance of the art of terraced arrangement seems often reduced to a picturesque disposal; misunderstood if not betrayed in its authenticity both as a product and as a process. Some case studies are proposed to point out this slipped issue, considering the Lake of Como as an elective observation area. By the presentation of some real examples, both virtuous and critical, a discussion and comparison with other contexts, both national and international, should eventually be favoured.

The search for improvements in the construction industry has made companies better know their production processes in order to reduce consumption of material and activity that do not add value to the product, as well as ensure better productivity of their teams. For these reasons, this research sought to measure, through a case study, indicators of labor productivity in the execution of the structural masonry of a residential building located in the city of São Carlos, SP, run by a small company. The results showed that the studied team has a higher productivity when compared to the indicators provided by the Sinapi and TCPO tables. In the analysis of time distribution, we observed significantly low unproductive activity and values of good and productive activity and compatible with values presented in the literature. Although it has occurred in a short period of time, this study enlightened that small businesses have optimized their processes in order to remain competitive in the marketplace, demonstrating the efficiency of their team.

In the current scenario of crisis in the country, construction companies need to invest in management and in process control. The PPC is one of the most complex processes in companies. This is due to the large number of variables that influence the system and the interdependence between them and external factors. This research was a case study conducted during the execution of a residential building, which had its planning in development and being applied daily. In order to carry out the control in the building site the PPC tool was applied weekly, with daily control. The main problems identified were: unfinished prior task, low productivity, lack of sub contractor´s labor, lack of labor and lack of building materials. Refining the PPC can identify more easily those responsible for delays and take corrective action on site.

The continuous rise in population, urbanization and expansion of cities has triggered a corresponding increase in construction and demolition activity. The frequent collapse of buildings attributed to poor structural design, building decay, and/or use of substandard materials has generated a substantial increase in construction refuse, also referred to as Construction and Demolition (C&D) Waste. This waste stream originates from residential, commercial, agricultural, institutional and industrial building projects for new builds, reconstruction, expansion, and refurbishments/rehabilitation. Most studies in Nigeria have generally focused on solid waste management without considering the uniqueness of C&D and giving it the attention needed, in order to achieve sustainable urban spaces that are highly functional, safe, convenient, and livable. This study seeks to investigate the different approaches and processes of C&D waste management in the City of Jos, in the Plateau State of Nigeria. The mix method was adopted for this research whereby quantitative and qualitative data was collected through a structured questionnaire for construction enterprises, as well as face-to-face interviews with the agencies responsible for waste management in the city. A total of 21 construction companies (representing about 10%) were randomly selected for questionnaire administration while interviews were conducted with the Plateau Environmental Protection and Sanitation Agency (PEPSA) and the Jos Metropolitan Development Board (JMDB) who are responsible for waste management. Investigations revealed that C&D waste consists of heavy and non-degradable materials such as: sheet metal roofing, sand, gravel, concrete, masonry, metal, and wood to mention only a few. The construction companies are solely responsible for: the collection, storage, transportation and disposal of wastes generated from their activities. Approximately 60-70% of the C&D waste materials are either reused, recycled or resold, while the remaining residual waste is indiscriminately disposed. Although the PEPSA and JMDB are responsible for waste management, their focus has been on establishing solid non-hazardous waste infrastructure systems, policies and plans. The absence of records of the quantity of C&D waste generated, the lack of financial data, and the omission of policies and plans for the C&D waste stream has resulted in a missed opportunity for a comprehensive and sustainable waste management strategy for the City and the state. To protect public health, valuable resources, and natural ecosystems, it is recommended that the C&D waste stream be included as part of the state’s waste management program, in consideration of the growing construction and demolition activity, by including C&D policies and guidelines.

Full textAbstract:
The evaluation of buildings in real conditions of use or post-occupancy evaluation, is the systematic study of buildings with the objective of decide their performance once they are inhabited; is a process of review and identification of successes and failures, in order to improve the conditions of existing buildings and to feed future designs, in search of residential satisfaction. Nowdays, the construction industry in Colombia does not have feedback processes regarding the operation of a building; Therefore, the research presented below proposes a tool for post-occupational evaluation - HEPO-, which is oriented to the analysis of buildings in use phase, in terms of meeting needs and preserving quality in the time of the materials, providing as a result the variables of study for the Colombian sector, in order to understand the performance dynamics, and proposes the mechanisms of collection and processing the information for the correct presentation of results, also presents the barriers at the time of HEPO application. In order to verify the effectiveness of the tool, it is validated in five housing projects in the city of Medellín, Colombia.

Full textAbstract:
The building and construction industry has witnessed many developments over the past few years. The most important of these developments is the use of Building Information Modeling (BIM). BIM technologies have contributed to the development of this industry significantly. So far, they have been used at the level of individual buildings and projects. Nowadays, the continuous need for development is forcing the transition to BIM on a wider level to include cities, through integration with other systems, mainly Geographical Information Systems (GIS). The integration between BIM and GIS will contribute to obtaining digital models for cities, or so-called City Information Modeling (CIM). CIM will contribute significantly to supporting the decision-making process, in addition to developing urban planning processes for cities. Furthermore, the CIM models will form the base for creating digital twins in order to conduct smart cities projects. In this research paper, we will explain how to take advantage of the overlap and integration between BIM and GIS in order to create a CIM model for a small region, as exemplified by Nizhny Novgorod in the Russian Federation. The area studied includes four main properties (a school, a garage, and two residential properties).

La ciudad contemporánea es la resultante de un crecimiento continuo y acelerado donde las lógicas proyectuales y de gestión producen impactos que se perciben en el paisaje y en el territorio. Tales dinámicas de transformación se reflejan en los bordes de la ciudad consolidada con el consumo de suelo agrario. Los bordes, la interfase entre ambas situaciones da lugar a un área que alterna el uso rural y el residencial disperso, afectando las condiciones ambientales de estos ámbitos suburbanos. La lectura interpretativa de esta nueva modalidad (urban sprawl) adquiere particularidades específicas en el contexto de las áreas metropolitanas de Rosario y Santa Fe registrando, en el periodo 2002-2012, las transformaciones en el uso residencial sea en su condición de barrio cerrado o abierto en el área suburbana.
Esta visión se aborda desde la observación del paisaje metropolitano contemporáneo y tiene entre sus objetivos más importantes, el de aportar a la construcción de nuevas herramientas que permitan valorar ese paisaje de borde, entre lo natural y lo construido, entendido como un recurso patrimonial sostenible en el tiempo. Esta investigación toma como antecedente el estudio comparativo e interpretativo de los procesos de transformación en los usos del suelo de las mencionadas áreas y se propone verificar, tanto en la centralidad como en los bordes y en las expansiones, las formas y modalidades de ocupación del suelo en relación a las características del paisaje resultantes de los procesos de suburbanización y expansión en la periferia. The contemporary city is the result of a continuous and rapid growth where logic and management of design produce impacts that are perceived on the landscape and territory. Those dynamics of change are reflected in the edges of the consolidated city and in the ownership of agricultural land. The edges, the interface between the two situations, results in an area that alternates rural and spread residential use, affecting environmental conditions in these suburban areas. The appreciation of this new modality (urban sprawl) acquires specific characteristics in the context of metropolitan areas of Rosario and Santa Fe, registering in the period 2002-2012, the transformations in the residential use – both in its condition of closed and open neighborhood in the suburban area. This point of view is approached from the observation of the contemporary metropolitan landscape, and it has among its main objectives to contribute to the construction of new tools to assess the landscape border between the natural and the built, understood as a sustainable heritage resource in time. This research takes as its antecedent the comparative and interpretive study of the processes of transformation in land use of the mentioned areas, and intends to verify in the centrality, as in the edges and the expansions, forms and modalities of soil occupation in relation to landscape features.

Full textAbstract:
Foam, a cellular material, is found all around us. Bone and cork are examples of biological cell materials. Many forms of man-made foam have found practical applications as insulating materials. NASA uses the BX-265 foam insulation material on the external tank (ET) for the Space Shuttle. This is a type of Spray-on Foam Insulation (SOFI), similar to the material used to insulate attics in residential construction. This foam material is a good insulator and is very lightweight, making it suitable for space applications. Breakup of segments of this foam insulation on the shuttle ET impacting the shuttle thermal protection tiles during liftoff is believed to have caused the space shuttle Columbia failure during re-entry. NASA engineers are very interested in understanding the processes that govern the breakup/fracture of this complex material from the shuttle ET. The foam is anisotropic in nature and the required stress and fracture mechanics analysis must include the effects of the direction dependence on material properties. Material testing at NASA MSFC has indicated that the foam can be modeled as a transversely isotropic material. As a first step toward understanding the fracture mechanics of this material, we present a general theoretical and numerical framework for computing stress intensity factors (SIFs), under mixed-mode loading conditions, taking into account the material anisotropy. We present mode I SIFs for middle tension — M(T) — test specimens, using 3D finite element stress analysis (ANSYS) and FRANC3D fracture analysis software, developed by the Cornell Fracture Group. Mode I SIF values are presented for a range of foam material orientations. Also, NASA has recorded the failure load for various M(T) specimens. For a linear analysis, the mode I SIF will scale with the far-field load. This allows us to numerically estimate the mode I fracture toughness for this material. The results represent a quantitative basis for evaluating the strength and fracture properties of anisotropic foam insulation material.

Full textAbstract:
Under the United States Department of Homeland Security (DHS) Assistance to Firefighter Grant Program, Underwriters Laboratories examined fire service ventilation practices as well as the impact of changes in modern house geometries. There has been a steady change in the residential fire environment over the past several decades. These changes include larger homes, more open floor plans and volumes and increased synthetic fuel loads. This series of experiments examine this change in fire behavior and the impact on firefighter ventilation tactics. This fire research project developed the empirical data that is needed to quantify the fire behavior associated with these scenarios and result in immediately developing the necessary firefighting ventilation practices to reduce firefighter death and injury. Two houses were constructed in the large fire facility of Underwriters Laboratories in Northbrook, IL. The first of two houses constructed was a one-story, 1200 ft, 3 bedroom, bathroom house with 8 total rooms. The second house was a two-story 3200 ft, 4 bedroom, 2.5 bathroom house with 12 total rooms. The second house featured a modern open floor plan, two- story great room and open foyer. Fifteen experiments were conducted varying the ventilation locations and the number of ventilation openings. Ventilation scenarios included ventilating the front door only, opening the front door and a window near and remote from the seat of the fire, opening a window only and ventilating a higher opening in the two-story house. One scenario in each house was conducted in triplicate to examine repeatability. The results of these experiments provide knowledge for the fire service for them to examine their thought processes, standard operating procedures and training content. Several tactical considerations were developed utilizing the data from the experiments to provide specific examples of changes that can be adopted based on a departments current strategies and tactics.
