Resumen

This research project deals with dynamic field testing of light-frame wood buildings with wood-based shear walls. The primary objective of the investigation is to evaluate the building code formula for estimating light-frame wood building’s fundamental period for seismic analysis, through intensive field testing and numerical modeling. The project also aims to propose an alternative simplified rational approach to seismic analysis of these structures. The paper presents ambient vibration testing results of light-frame wood buildings in Canada. The dynamic characteristics of the measured buildings, such as natural frequency, mode shapes, and equivalent structural damping were obtained from frequency domain analysis of ambient motion records. Using a simplified method of period estimation based on the Rayleigh approximation while using the building mass and replacing the stiffness of shear walls by their length showed reasonable fit when compared with the finite element model results and ambient vibration testing measured periods. A formula was developed based on the regression analysis of the tested buildings. The expression is a function of building height, floor area, and shear wall length and it was shown to provide a reasonably good fit with the measured results.

Resumen

The suitability of viscous fluid dampers for seismic protection of light-framed wood buildings is investigated in this paper. Nonlinear finite-element models of wood building components (shear wall) and systems (three-dimensional buildings) are developed and numerical analyses are performed to evaluate their response to seismic loading. For both the single wall and the building system, seismic protection is provided by installing viscous fluid dampers within the wall cavities. The results of the numerical analyses demonstrate the ability of fluid dampers to dissipate a significant portion of seismic input energy, reducing the inelastic strain energy demand on the wood framing system. In addition, the study revealed some important practical issues associated with implementation of fluid dampers within light wood-framed buildings.

Resumen

In the middle of the 20th century, Paul Rudolph’s design practice of light wood residences in Sarasota area was well adapted to the local hot and humid subtropical climate. By tracing the origin of Paul Rudolph’s thought of climate responsive design, it’s possible to realize the design features of Paul Rudolph’s early works from heat protection and ventilation, and sum up the strategies and construction of his light wood residences for climate responsive design. Based on the characteristics of subtropical heat and humidity, Rudolph focused on innovations in building facades, roofs, and spaces, and proposed a series of climate-responsive design strategies and methods. Rudolph’s light wood practice has its own value in terms of technical principles, material technology, and regional characteristics, which are both rational and perceptual, and has enlightening value for the application of light buildings in subtropical areas and the design of contemporary light wood buildings.

Resumen

Abstract One of the 17 Sustainable Development Goals (SDG) set out in this agenda, objective 11 is related to the search for more sustainable cities and communities. This study wishes to contribute in this effort, presenting a method application to evaluate the performance of light wood frame buildings in Brazil. The structure of the method used, named MEPLWF, is based on five dimensions, which involve criteria and sub-criteria that analyse technical, social, environmental and economic requirements to evaluate buildings. It allows the examination of the operating results of buildings and the discovery of performance-related problems. The proposed method was applied in a real case study in southern Brazil, during the pre-occupation phase of the building. As a result, the performance identified in the building was 94%, which is a high performance. The application of the method in this case study diagnosed points that should be reviewed by the construction company, such as items related to fire protection and safety, flexibility and adaptability of the building system, environmental plan, energy efficiency and Costs.

Resumen

Abstract Light wood frame (LWF) is a construction system considered innovative in Latin American countries, which has been used as a strategy to mitigate housing deficits. Since this construction system is new in these countries, a rigorous assessment of their manufacturing, construction and use is essential. Thus, this research aims to develop a method to evaluate the performance of LWF buildings in Brazil to help builders optimise the construction system in the country. The study made use of the literature to identify valuable criteria for a building performance evaluation using qualitative tools, such as questionnaires and the Delphi technique, to select specific criteria for the LWF system. Finally, statistic tools, criteria groups and weights were generated. As a result, the study established a framework with 5 dimensions, 19 criteria and 41 sub-criteria, thus understanding which the most important criteria are to be evaluated during the LWF building performance evaluation. Finally, the criteria with the highest scores refer to structural durability, maintenance, sealing and control of thermal, acoustic, visual and air quality comfort.

Resumen

In the construction of log building, the building's insulation effect is mainly achieved by the timber tightly connected, which usually requires a large flat timber that lead to the consumption of high-quality wood.In recent years, by the decline in quality of forest resources, existing log buildings are constructed with fast-growing wood which small diameter, and larger curvature. Compared with the traditional log building, the log wall constructed with fast-growing wood has wider gap, poor insulation and poor pest control.So it greatly increased consumption of firewood for heating.To compensate for this defect, this paper make a study of log building constructions wall structured with light weight earth material. Mixture of plant fibre and cement, is used as main reinforce component, together with raw soil to enhance the ability of anti-cracking and heat preservation, fixing the mixture of ligth clay on inner side of the construcion's wall to enhance the ability of heat preservation and getting smooth wall surface by fill the gap in the wall, and easy for decorating interior wall.

Resumen

The floor impact noise generated in a building often causes problems among residents. The floor impact sound insulation performance of timber construction buildings is lower than that of concrete construction. However, due to the large supply of wood and the stress-relieving effects of wood, the use of wood is being promoted around the world. In Japan, the Act on the Promotion of the Utilization of Wood in Public Buildings was enforced to promote the use of CLT (Cross Laminated Timber) for the effective use of wood. We have been experimentally investigating the effect of floor finish structure in CLT model building. In this paper, we report the measurement results of the change in floor impact sound insulation performance when the suspended ceiling structure was changed. As results, it was confirmed that the effect of the sound-absorbing material in the ceiling cavity and the effect of the double-layer ceiling board were effective. In addition, it was clarified that the dry-type double floor structure with rubber vibration insulator on its legs is an effective floor finish structure for improvement of heavy and light weight floor impact sound insulation performances.

Resumen

Recent natural disasters around the world including both tsunamis and hurricanes, have highlighted the inability of wood buildings to withstand wave and surge loading during these extreme events. Little is known about the interaction between coastal residential light-frame wood buildings and wave and surge loading because often little is left of the buildings. This leaves minimal opportunity for forensic investigations. This paper summarizes the results of a study whose objective was to begin to better understand the interaction between North American style residential structures and wave loading. To do this, one-sixth scale residential building models typical of North American coastal construction, were subjected to tsunami wave bores generated from waves of heights varying from 10 cm to 60 cm. The lateral force produced by the wave bores were, as expected, found to vary nonlinearly with parent wave height.

Resumen

Light-frame shearwall assemblies have been successfully used to resist gravity and lateral loads, such as earthquake and wind, for many decades. However, there is a need for maintaining the structural integrity of such buildings even when large openings in walls are introduced. Wood portal frame systems have been identified as a potential alternative to meet some aspects of this construction demand. The overarching goal of the research is to develop wood portal frame bracing systems, which can be used as an alternative or in combination with light-frame wood shearwalls. This is done through investigating the behavior of wood portal frames using the MIDPLY shearwall framing technique. A total of 21 MIDPLY corner joint tests were conducted with varying bracing details. Also, a finite element model was developed and compared with test results from the current study as well as studies by others. It was concluded from the corner joint tests that the maximum moment resistance increased with the addition of metal straps or exterior sheathings. The test results also showed a significant increase in the moment capacity and rotational stiffness by replacing the Spruce-Pine Fir (SPF), header with the Laminated Veneer Lumber (LVL) header. The addition of the FRP to the standard wall configuration also resulted in a significant increase in the moment capacity. However, no significant effect was observed on the stiffness properties of the corner joint. The FE model was capable of predicting the behavior of the corner joints and the full-scale portal frames with realistic end-conditions. The model closely predicted the ultimate lateral capacity for all the configurations but more uncertainty was found in predicting the initial stiffness.The FE model used to estimate the behavior of the full-scale portal frames constructed using the MIDPLY framing techniques showed a significant increase in the lateral load carrying capacity when compared with the traditional portal frame. It was also predicted using the full-scale FE model that the lateral load carrying capacity of the MIDPLY portal frame would increase with the addition of the metal straps on exterior faces. A parametric study showed that using a Laminated Strand Lumber (LSL) header increased the lateral load carrying capacity and the initial stiffness of the frames relative to the SPF header. The study also showed that there was an increase in the capacity if high strength metal straps were used. Doubling of the nail spacing at header and braced wall segment had a considerable effect on the lateral capacity of portal frame. Also, the initial stiffness was reduced for all the configurations with the doubling of the nail spacing at the header and braced wall segment in comparison with the reference frame.

Resumen

Constructing multi floor buildings by light weight material have increased recently. There are many advantages of using light weight material, such as wood, for the environment. However, one of the deficiencies of lightweight material is the acoustic performance. Transmission of sound and vibration through floors in multi floor buildings in wood is a drawback to be considered. There are many studies that have addressed this issue. It is most common to make a finite element models well as experiments in laboratory. In these studies the material properties in the FE model are probably often adjusted to correlate to the laboratory experiments, since there is a large spread in material properties found in literature. This thesis however tries to elaborate on the actual material properties of the included wooden elements. Dynamic testing is done to determine the spread (here spread means gap between material properties) in material properties of wooden elements. The materials tested are chipboards and two types of wooden beams. The examined beams are both normal wooden beams and laminated veneer lumber beams. When the dynamic behaviour is known for the wooden parts, they are assembled to two small floor systems. The floor systems consist of four beams and one wooden board. The assembly is dynamically tested in laboratory and in FE software. The FE model used the known material properties for each individual building part. The results from the FE model correlate well with the laboratory tests. This shows that when material properties are known a FE model can predict the real behaviour. However, the examined material properties show a large spread from beam to beam, etc and a better knowledge about the material properties of used wooden parts is needed.
Att bygga flervåningshus med lätta byggmaterial har blivit allt vanligare. Det finns många fördelar med att använda lätta material, såsom trä. En av fördelarna är att det är skonsamt för miljön. Emellertid är en av bristerna i lättviktsmaterial den akustiska prestandan. Överföring av ljud och vibrationer genom golv i flervåningshus i trä är en nackdel att överväga. Det finns flera studier som har behandlat denna fråga. Ofta görs finita element modeller samt tester i laboratorium. I dessa studier justerar man materialegenskaperna i FE-modellen för att korrelera mot laboratorieexperiment. Detta eftersom det finns en stor spridning i materialegenskaperna för trä i litteraturen. Med detta examensarbete, undersöks de faktiska materialegenskaperna hos träelementen genom försök. Dynamiska tester utförs för att bestämma spridningen i materialegenskaper. De testade materialen är spånskivor och två typer av träbalkar. De undersökta balkarna är både normala träreglar och laminerade faner balkar. När det dynamiska beteendet är känt för trädelarna, monteras de ihop till två små golvsystem. Golvsystemen består av fyra balkar och en träskiva. Den assemblerade modellen testas både dynamiskt i ett praktiskt försök och i ett FE program. I FEmodellen används de tidigare framtagna faktiska materialegenskaper för varje ingående enskild byggnadsdel. Resultaten från FE-modellen korrelerar väl med de praktiska experimenten. Med detta examensarbete visas att när materialegenskaperna är kända kan FE-modellen förutsäga det verkliga beteendet. De undersökta materialegenskaperna visar dock en stor spridning från balk till balk, etc. och mer kunskap om materialegenskaper hos trädelar behövs.

Ambient vibration (AV) field tests were conducted on several multi-storey wood and beam-and-post buildings in Canada. Modal parameters of measured buildings, such as natural frequency, mode shapes and equivalent structural damping were obtained from Frequency Domain (FD) analysis of ambient motion records. Experimental and numerical investigations were performed to evaluate the effect of non-structural components, and the connectivity between firewall-separated buildings, on dynamic properties of light-frame wood buildings. The study provides a reliable expression for building period estimate based on field testing and numerical modeling.

Resumen

Light-frame wood structures are the most prevalent construction type in North America, representing over 90% of the residential building stock. Many of these buildings were built prior to the adoption of seismic engineering design practices and thus may be vulnerable in a seismic event. The primary objective of the research is to examine the use of numerical models to predict the seismic behaviour of light-frame wood structures. Models for (i) a full-scale two-storey house, (ii) a full-scale classroom, and (iii) a two-storey school block were created in light-frame wood non-linear analysis packages. The first two models were validated with full-scale shake table tests. The effect of sheathing type, nailing schedule, openings and ground motion characteristics on the seismic behavior of light-frame wood buildings were investigated. A three-dimensional model of a two-storey light-frame timber house with different sheathing configurations was calibrated using non-linear dynamic analysis to the full-scale experimental shake table results. The model of the test structures was able too predict the time-history response of the drift with reasonable accuracy. The contributions of the strength and stiffness from the openings and non-structural sheathing were included in the model. A detailed numerical model (each nail, framing member, hold-down and panel are modeled), as well as a global numerical model was used to predict the seismic behaviour of an additional dynamic shake table testing was also conducted on a full-scale classroom. The effect of openings, sheathing and ground motion duration was further investigated. Finally, the seismic performance of existing structures and the performance of several retrofit options was investigated with the validate modeling techniques using non-linear dynamic analysis of a typical school block built between 1950 – 1960 in Vancouver. The retrofit options met the target performance objectives.

Resumen

In recent time, some of the construction processes of multi-storey timber buildings are achieved by using prefabricated volume modules since this method is very beneficial due to its high prefabrication level and the fast on-site assembly of the modules. The main structural component of these modules is a light-frame shear wall that stabilizes these modules from the effect of horizontal forces. A shear wall typically consists of timber frame with studs and rails and sheathing panels connected by dowel type fasteners to one or both sides of the frame. The structural behavior of shear wall and its racking performance is controlled by adequate design of its mechanical joints where sheathing-to-framing joints is the key issue in evaluating the overall behavior of shear wall. This study mainly deals with modelling of light-frame shear walls based on linear elastic characteristic for sheathing-to-framing joints. The objective of this study is to create two effective computer-based models (beam-spring-shell and beam-spring-shell-solid) to predict linear behavior of light-frame shear walls. In addition, the study deals with an experimental investigation of various types of short light-frame shear walls. Finally, the study compares modelling and experimental results to verify that they are in good agreement and that an efficient FE model is able to predict the structural behavior of shear walls for a short computational time. The study optimizes use of beam-spring-shell model which is as reliable as the beam-spring-shell-solid model, emphasizing its advantages over the resource-consuming solid model. The beam-spring-shell model is efficient and can be implemented and used for design and analysis of modular-based timber buildings.

Resumen

Given the building sector’s substantial contribution to global energy use and green house gas (GHG) emissions, it is of great importance that only the most effective building envelopes are utilized. Conventional light-frame wood building envelopes are highly popular due to their ease of construction and building economy; however the life cycle performance of the building envelope is often overlooked when this selection is made. Although insulated concrete form (ICF) building envelopes generally require a substantially higher embodied energy input, it should be considered that improvements during a building’s operation phase can offers significant energy returns, ultimately reducing the building’s life cycle energy use and GHG intensity. Therefore, an assessment is conducted regarding the life cycle energy use and GHG intensity of the ICF building envelope, in addition to two light-frame wood building envelopes; the average light wood frame envelope (U.S. Department of Energy, 2007), and a more highly insulated wood frame envelope. The operation phase of the building envelopes proves to be of greatest significance, as it is attributed to 95- 97% of the total life cycle energy use, and 93-96% of life cycle GHG emissions, assuming a 100 year life cycle. Ultimately, the life cycle performance of the ICF building envelope is superior to the two wood frame envelopes due to its improvements in the operation phase. The ICF building envelope has a life cycle energy requirement of 11% to 14% less than the two light-frame wood envelopes, and a 10% to 12% lower life cycle GHG intensity. Although the increased thermal resistance certainly contributes to the superior life cycle performance of the ICF envelope, the improved infiltration leakage area of the envelope is key to its operational performance, and subsequently to its improved life cycle performance. End of life energy use for the demolition, recycle, and disposal of the building envelopes is nearly negligible, as it is attributed to less than 0.3% of the life cycle energy for any of the envelope scenarios.

Resumen

This thesis describes the development of numerical models for predicting the performance of three-dimensional light wood-framed buildings under static loading conditions and subjected to dynamic excitations. The models have been implemented into a package of nonlinear finite element programs. They satisfy the general requirements in the study of the structural behaviour of commonly applied light-frame construction. The models also deal with building configurations and loading conditions in a versatile manner. The application of these programs, therefore, can provide solutions to a wide range of investigations into the performance of wood light-frame buildings. These investigations may include the analyses of an entire three-dimensional light-frame building, an individual structural component, and a single connection containing one to several nails with varied material and structural components and combined loading conditions. These buildings and components can have irregular plan layouts, varied framing and sheathing configurations, and different nail spacings with or without openings. The models were verified and tested on theoretical and experimental grounds. Theories of mechanics were applied to examine the models and related algorithms, while experimental results were used to validate the finite element programs and to calibrate the basic parameters required by the models. Besides the test data from previous shear wall studies, three-dimensional building tests were conducted to provide the data required in the model verification. In the experimental planning phase, the programs were intensively employed to help select the correct configurations of the test specimens. The experimental session contained four tests of a three-dimensional wood-framed structure: two static tests and two earthquake tests. These tests provided extensive information on the overall load-deformation characteristics, dynamic behaviour, torsional deformation, influence of dead load, overturning movement, failure modes, natural frequencies, and corresponding mode shapes of the test systems. The predicted behaviour of the test specimens by the programs is in good agreement with test results. This indicates that the programs are well suited for the investigation of the general behaviour of wood lightframe systems and for the study of load sharing and torsional effects on three-dimensional buildings due to structural and material asymmetries.

Resumen

Since 2004 there have been multiple devastating tsunamis around the globe triggered by large magnitude earthquakes; with the most recent being the Tohoku, Japan tsunami in March 2011. These tsunamis have caused significant loss of life and damage to the coastal communities impacted by these powerful waves. The resulting devastation has raised awareness of the dangers of tsunamis and the Network for Earthquake Engineering Simulation (NEES) housesmash project (NEEShousesmash), was started to investigate several different areas of tsunami inundation. The work presented in the following two manuscripts was performed at the O.H. Hinsdale Wave Lab and Gene D. Knudson Wood Engineering Lab, which are located at Oregon State University. This work represents a small portion of the total NEEShousesmash project, and is focused on improving the knowledge and predictability of tsunami loading and structural performance. The first manuscript investigates tsunami wave impact on full scale light-frame wood walls, and compares the measured forces to calculated values using the linear momentum equation, previously evaluated by Cross (1967). The results show for each wave height tested a peak transient force followed by a sustained quasi-static force, with a ratio of transient force to quasi-static force of 2.2. The results also show that the linear momentum equation did an acceptable job of predicting the measured transient forces on the walls to within ±10%, and that increased wall flexibility, 2x4 vs. 2x6 dimensional lumber, resulted in lower measured transient forces when subjected to similar tsunami wave heights. These results are important for practical use because the linear momentum equation is a simple equation to use, that only requires a couple of site specific input variables. The second manuscript is a continuation of the work done in the wave lab for the first manuscript. These experiments provide a starting point for expanding the testing of the structural response and performance of larger scale structures subjected to tsunami wave loads. By simulating tsunami loading in a traditional structures laboratory, the inherent limits of testing structural performance in small scale tsunami laboratory facilities is removed. The results show that a light-frame wood shear wall, built to current standards, is susceptible to premature failures from concentrated impact loads at intermediate heights compared to the design strength at full height. It is also shown that the out-of-plane walls subjected to both elastic and inelastic loads behave like a one way slab with minimal load sharing between adjacent studs. The failures observed during the hydrodynamic wave testing of the nailed connection between the bottom plate and studs was successfully reproduced, and shows that current construction standards are not fully utilizing the available capacity of each stud when subjected to tsunami waves. The reinforcement of this connection with traditional metal brackets would help increase the capacity of the out-of-plane wall to resist tsunami wave loads.

Resumen

Engineered wood products are considered as best building materials due to environmentally friendly. Huge change to the way in which wood has been utilized in primary application of construction in the course of the most recent 25 years are in light of decreased admittance to high strength timber from growth forests, and the turn of events and creation of various new design of manufactured wood products. Engineered wood products are available in different variety of sizes and measurements like laminated veneer lumber, glued laminated timber, finger jointed lumber, oriental strand board etc. It is utilized for rooftop and floor sheathing, solid structure, beams and the hull of boats. This review objectively explores not only the environmental aspects of the use of different engineered wood composites as a building material, but also their economic aspects, to understand their effect on sustainability.

Resumen

Wood plastic composites (WPCs) is one of crucial and potential engineering wood products that has been extensively employed in the fields of landscape, transportation, municipal engineering and building construction. It has gradually been used to replace the conventional wood-based composites. This chapter aims to introduce the properties and development of WPCs and illustrate how defects in their mechanical properties, biological and aging resistance, and flame retardance affect their global development. Herein, the effects on the biological durability of WPCs against algae, mold, fungi, and termites made with various wood species with different chemical extractive compositions, the natural weathering performance of WPCs and the mechanisms of protection against ultraviolet light and moisture, the effectiveness and mechanism of reinforcement of WPCs by novel alloy modification of linear and aromatic polyamides are reviewed. Additionally, the flame retardance properties, common testing methods as well as the performances of novel flame retardants for WPCs, are comparatively described. Lastly, the limitations and prospects of WPCs in future construction applications are also discussed.

Resumen

Wood composites are made from various wood or ligno-cellulosic non-wood materials (shape and origin) that are bonded together using either natural bonding or synthetic resin (e.g. thermoplastic or duroplastic polymers), or organic- (e.g. plastics)/inorganic-binder (e.g. cement). This product mix ranges from panel products (e.g., plywood, particleboard, strandboard, or fiberboard) to engineered timber substitutes (e.g., laminated veneer lumber or structural composite lumber). These composites are used for a number of structural and nonstructural applications in product lines ranging from interior to exterior applications (e.g. furniture and architectural trim in buildings). Wood composite materials can be engineered to meet a range of specific properties. When wood materials and processing variables are properly selected, the result can provide high performance and reliable service. Laminated composites consist of wood veneers bonded with a resin-binder and fabricated with either parallel- (e.g. Laminated Veneer Lumber with higher performance properties parallel to grain) or cross-banded veneers (e.g. plywood, homogenous and with higher dimensional stability). Particle-, strand-, or fiberboard composites are normally classified by density (high, medium, low) and element size. Each is made with a dry woody element, except for fiberboard, which can be made by either dry or wet processes. Hybrid composites based on wood wool, particles, and floor mixed with cement or gypsum are used in construction proving high weathering and fire resistance in construction. The mixture with plastics (PP or PE) and wood floor open a new generation of injected or molded Wood Plastic Composites (WPC), which are able to substitute plastics for some utilizations. In addition, sandwich panels with light core made from plastic foams or honeycomb papers are used in the furniture industry.

Resumen

Energy and human history go hand in hand. For most of the time that humans have been on earth, energy was used at a very low level, mostly by burning wood for cooking and warmth. This is still the case for large areas of the planet, especially in much of Africa and parts of Asia and South America. As human populations grew, forests were decimated to obtain fuel, resulting in the collapse of several societies (1). Coal was discovered in England in the thirteenth century and began to be used extensively beginning in the 1500s. Between 1570 and 1603, during the reign of Elizabeth I, coal became the main source of fuel for England (2). This was, not coincidentally, also during the time of the Little Ice Age, when there was a great need for fuel to keep warm. Coal transformed England, for better and for worse. The development of the coal-based steam engine by Thomas Newcomen in 1712, with further critical developments by James Watt and Matthew Boulton, led to the Industrial Revolution beginning in about 1780. Coal built England into the world’s most powerful country during the nineteenth century. At the same time, it brought about unbelievable pollution, which drastically shortened lives, and it led to child slave labor in factories and mines. Coal had been discovered even earlier in China and was being used for iron production in the eleventh century (2). Coal was discovered in Appalachia in the United States in the mid-eighteenth century and quickly became its most abundant source of energy. This led to the industrial development of the United States, the building of canals to transport coal, and the construction of railroads to connect the far reaches of the country. Wherever large sources of coal were found, societies were transformed. Coal was fine for running steam engines and cooking or keeping warm, but what people wanted desperately was a better source of light for their homes and businesses.

Resumen

This paper reports on the development of a conceptual design, construction and instrumentation of an experimental facility that can be used to carry out experimental research towards increasing energy efficiency in buildings. The overarching idea is to construct a system that emulates the scaled dimensions and materials of a typical building structure. The sub-scale testbed consists of a two-floor building configuration with dimensions of 1.2 m × 0.92 m × 1.1 m. The building structure is made out of wood, and covered with drywall and fiberglass insulation. Fixed walls are selected for the first floor whereas movable walls are incorporated into the second floor to study the effects of different room configurations. Four staircase openings enable airflow between the two floors. The second floor has a tiled-style ceiling and removable walls that allow for connectivity of sensors and actuators. A set of heating and cooling sub-systems, consisting of light bulbs and thermoelectric coolers connected to fans, are used for each room in the building. Both the set of light bulbs as well as the cooling system are powered through a relay box, and connected to a computer via LabVIEW which also interfaces the different sensing and actuating devices. The capabilities of the experimental facility are tested by implementing time-dependent heating- and cooling-processes and an on-off control strategy on a two-room prototype. Preliminary results demonstrate that the experimental testbed offers a reliable and versatile experimental system for research purposes.
