Influence of Temperature on Laminated Glass Performances Assembled with Various Interlayers

The increasing demand for use of laminated glass in building facades is the driving force for new interlayers testing and their implementation. Architects’ and engineers’ requests require searching for new solutions and processes of lamination. Intelligent facades, electrochromic windows, integrated photovoltaics, integrated lighting, enhanced solar control, acoustic pollution reduction, wires incorporation, use of special sealants and glues are some of the design drivers of new laminated structures. Laminated safety glass is composed of two or more glass panes bonded by one or more interlayers. The interlayers are typically soft polymers like polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyurethane (PU) or ionomer. Today, there are many interlayers on the market with a large variation in their properties. For some projects, it is a challenging task to choose the optimal interlayer.

Control strategies for intelligent glazed façade and their influence on energy and comfort performance of office buildings in Denmark

Abstract The research aims to develop control strategies for intelligent glazed facades and investigate the influence of different control strategies on energy and comfort performance in office buildings. The intelligent glazed facade is capable of controlling the thermal, solar and mass transmittance by controlling shutters, blinds and openings. The facade and building services are designed and controlled holistically to optimize the indoor comfort (thermal, visual comfort and indoor air quality) and minimize the energy demand by heating, cooling, lighting and ventilation. The study is conducted numerically utilising a simplified hourly calculation method developed to calculate yearly energy and comfort performance of an office room equipped with an intelligent facade. The simplified method is verified by the Danish dynamic building simulation tool BSim and experimental test in a full scale test facility at Aalborg University (Cube). Results show that the annual primary energy demand of an office building with intelligent glazed facade can be reduced by approx. 60% compared with the same building with a static facade. Utilising the properties of an intelligent glazed facade, buildings can more easily comply with the future Danish Building Class 2020 as stipulated in the Danish Building Regulation 2010, BR10. The comfort performance of the building can also be improved using an intelligent glazed facade.

Development of Intelligent Façade Based on Outdoor Environment and Indoor Thermal Comfort

Abstract In the last decades, the development of innovative solutions is considered as a prominent issue for achieving sustainability within the built environment. Facades are crucial to energy consumption and comfort within buildings. Incorporating intelligence in their design is an effective way to achieve low energy consumption buildings. The ability of specific facade systems to work reliably and effectively is one of the challenges towards sustainability. This study presents the state of art for intelligent facades at different outdoor environment in different climates. In addition the indoor environmental parameters such as thermal comfort, indoor air quality and visual comfort are outlined. The study concluded that intelligent facades in buildings and indoor thermal comfort require more development targeting low energy buildings and thermal comfort.

Integration of Environmental Sensors with BIM: case studies using Arduino, Dynamo, and the Revit API

This paper investigates the feasibility of connecting environmental sensors such as light, humidity, or CO 2 receptors to a building information model (BIM). A base case was created in Rhino; using Grasshopper and Firefly, a simple digital model responded to lighting-levels detected by a photoresistor on an Arduino board. The case study was duplicated using Revit Architecture, a popular BIM software, and Dynamo, a visual programming environment, in an innovative application. Another case study followed a similar procedure by implementing the Revit API directly instead of using Dynamo. Then the process was reversed to demonstrate that not only could data could be sent from sensors to change the 3D model, but changes to parameters of a 3D model could effect a physical model through the use of actuators. It is intended that these virtual/physical prototypes could be used as the basis for testing intelligent facade systems before constructing full size mock-ups.

Verification of a simplified method for intelligent glazed façade design under different control strategies in a full-scale façade test facility – Preliminary results of a south facing single zone experiment for a limited summer period

The research aims to verify a simplified calculation method for intelligent glazed facade under different control strategies (night shutter, solar shading and natural ventilation). The method is developed to simulate the energy performance and indoor environment of an office room installed with intelligent facades. The calculation results of heating and cooling needs are verified by experimental data collected in a full-scale test facility (Cube) with south-facing façade at Aalborg University (DK) during summer period from 18th to 22nd June 2014. According to the results of the comparison, the calculated air temperature has good agreements with the measurements, with the R2 value of 0.8. Additionally, the total cooling energy consumptions measured in the experiment are 30% lower than the calculated. The experiment was conducted in the test facility with only south-facing façade and during a short summer period, which limits the verification of the method.When using water system in the chilled beam to cool down test room, it needs to be noticed that the forward water temperature should be controlled not to be higher than the air temperature of the test room when there is no cooling need in the test room; otherwise the chilled beam will release heating to the test room, which could influence the accuracy of the result.National Instrument (NI) CompactRIO is used to acquire measured data from different sensors and send signal to control building services like ventilation, heating, cooling and artificial lighting. The whole process is realized with the help of Labview.

Development of a simplified method for intelligent glazed façade design under different control strategies and verified by building simulation tool BSim

The research aims to develop a simplified calculation method for intelligent glazed facade under different control conditions (night shutter, solar shading and natural ventilation) to simulate the energy performance and indoor environment of an office room installed with the intelligent facade. The method took the angle dependence of the solar characteristic into account, including the simplified hourly building model developed according to EN 13790 to evaluate the influence of the controlled façade on both the indoor environment (indoor air temperature, solar transmittance through the façade and the illuminance level on a chosen point) and the energy performance of the room.The parameters calculated by the simplified method were compared with the Danish building simulation tool BSim in an hourly calculation with the weather data of the Danish reference year. By using the simplified method, it is possible to calculate the whole year performance of a room or building with intelligent glazed façade, which makes it a less time consuming tool to investigate the performance of the intelligent façade under different control strategies in the design stage with acceptable accuracy. Results showed good agreement between the simplified method and BSim in terms of simulating the energy and comfort performance of the room.

Advice tool for early design stages of intelligent facades based on energy and visual comfort approach

Increased awareness on environmental issues, together with requirements imposed by implementation of energy efficiency codes, has generated the need for tools that evaluate thermal performance of buildings. Their objective is to ensure compliance and certification. However, existing computer models are still rudimentary with many limitations for use in early design stages of any architectural project. They require exact data in a stage when designers consider conceptual ideas from a range of options rather than precise details and numbers. Design tools that suggest solutions based on ideas are rare. This disadvantage can be seen in the planning of intelligent facades, where the number of possible configurations can be overwhelming and decisions made in early stages have profound effects on energy and comfort performance. This paper presents NewFacades, a model that helps pass from ideas to significant concepts in the design of intelligent facades. It uses energy and visual comfort strategies abstracted from a prescriptive energy code for hot climates to suggest a range of good starting solutions. Designers can have energy and visual comfort estimations to these alternatives through an advanced stage energy simulation program such as EnergyPlus, or explore them further with other tools. Methods used by the tool are presented here in the context of sample cases. By working on energy principles or relying on local existing energy standards, the model can be extended to all types of climates.
