2. ENVIRONMENTAL THERMAL COMFORT OF A REDUCED MODEL USING CROSS-LAMINATED TIMBER
ABSTRACT The challenges for the use of the cross-laminated timber (CLT) system in the Brazilian agricultural market are significant. This study evaluated the thermal performance of fiber cement tiles associated with a CLT non-conventional structure compared to those of ceramic, fiber cement and aluminum roof tiles based on following thermal comfort indexes (

3. Uso de sistemas modulares vegetados para promoção da saúde urbana e atenuação do estresse térmico
RESUMO O processo de urbanização possui efeitos significativos no microclima local, resultando no surgimento das ilhas de calor e comprometimento das condições térmicas no interior de habitações. A aplicação de sistemas modulares vegetados em telhados ou coberturas surge como alternativa à melhoria das condições térmicas no interior de habitaç�

4. Crack and mechanical behavior of CFRP plate-reinforced bridge roofs under high temperature with different anchoring measures
Abstract This paper investigates the crack and mechanical behavior of CFRP plate-reinforced bridge roof under high temperature with different anchoring measures. Six CFRP-reinforced test beams with different anchoring schemes were designed and constructed. The beam specimens, after the high temperature effects, were tested under four-point bending loads. The

5. DESHADOWING OF HIGH SPATIAL RESOLUTION IMAGERY APPLIED TO URBAN AREA DETECTION
Abstract Different built-up structures usually lead to large regions covered by shadows, causing partial or total loss of information present in urban environments. In order to mitigate the presence of shadows while improving the urban target discrimination in multispectral images, this paper proposes an automated methodology for both detection and recovery

6. Experimental Studies on Shear Resistance Performances for the Shear key of H Shape Steel Spatial Grid Roofs
Abstract In this paper, a new type of structure was introduced. The spatial steel grid structure was composed of the top layer, lower layer H-shaped steel ribs and square steel tubes. The shear key is the key part of the structure.Based on the real dimensions of a practical prototype,two sets of full-scale shear key specimens were made, one of which has vert

7. INFLUENCE OF EXPOSURE TIME TO OPERATING TEMPERATURE ON SHEAR STRENGTH OF WOOD USED IN ROOF STRUCTURES
ABSTRACT Wood is one of the main materials used in the constructing of covering structures (roofs) because of its versatility. Under this situation, due to solar radiation incidence, the temperature can exceed 60 °C and, such as other environmental conditions, influence the mechanical properties of the wood in use. The aim of this research was to study the

8. The Photovoltaic Generation and its Energy Contribution and Demand Shifting at the Center Headquarters of the Federal University of Technology - Paraná - Campus Curitiba
ABSTRACT Distributed photovoltaic (PV) generation is characterized by the application of several small power plants in urban centers. This form of energy deserves special mention due to the possibility of installation in existing areas such as roofs and facades. Thus, the implementation of these systems represents positive modifications of the urban scenario

9. GREEN ROOF: SIMULATION OF ENERGY BALANCE COMPONENTS IN RECIFE, PERNAMBUCO STATE, BRAZIL
ABSTRACT Green roof is a technology that consists of the use of soil and vegetation installed in the roof of buildings, being a great solution to combat heat islands. Thus, this study aimed to compare micrometeorological changes and their effect on the energy balance of non-vegetated (slab) and vegetated building roofs by means of a simulation model calculat

10. SIMILITUDE AND THERMAL PERFORMANCE ON NON-CONVENTIONAL ROOFS
ABSTRACT The objectives of this study were to evaluate the thermal comfort and the similitude between prototypes and reduced models, using non-conventional coverage with green roof and expanded clay aggregate, supported on wood frame structure. For this, were determined the Black Globe Temperature and Humidity Index (BGHI), the Human Discomfort Index (HDI),

11. THERMAL ENVIRONMENT OF TABLE GRAPE PACKING HOUSES IN THE SÃO FRANCISCO VALLEY
ABSTRACT The aim of this study was to characterize the thermal environment of the sorting and packing sectors of small, medium and large packing houses in the São Francisco Valley, Northeast of Brazil. Micrometeorological data were monitored every 15 minutes for 20 days during winter 2014 and summer 2015. The parameters evaluated were air temperature (°C),

12. SOWS AND PIGLETS THERMAL COMFORT: A COMPARATIVE STUDY OF THE TILES USED IN THE FARROWING HOUSING
ABSTRACT The global animal production is increasing as expected to meet world demand for food, especially for meat products. This research aimed to investigate the effect of two types of roofs (clay and fiber-cement tiles) in a tropical area on the thermal comfort of farrowing sows and piglets. Twelve sows and forty-eight piglets were observed during summer
