  • Airflow Simulations Around OA Intake Louver with Electronic Velocity
    Airflow Simulations around OA Intake Louver with Electronic Velocity Sensors Hwataik Han*1, Douglas P. Sullivan2 and William J. Fisk3 1 Professor, Kookmin University, Korea 2 Research Associate, Indoor Environment Department, Lawrence Berkeley National Laboratory, USA 3 Director, Indoor Environment Department, Lawrence Berkeley National Laboratory, USA Abstract It is important to control outdoor airflow rates into HVAC systems in terms of energy conservation and healthy indoor environment. Technologies are being developed to measure outdoor air (OA) flow rates through OA intake louvers on a real time basis. The purpose of this paper is to investigate the airflow characteristics through an OA intake louver numerically in order to provide suggestions for sensor installations. Airflow patterns are simulated with and without electronic air velocity sensors within cylindrical probes installed between louver blades or at the downstream face of the louver. Numerical results show quite good agreements with experimental data, and provide insights regarding measurement system design. The simulations indicate that velocity profiles are more spatially uniform at the louver outlet relative to between louver blades, that pressure drops imposed by the sensor bars are smaller with sensor bars at the louver outlet, and that placement of the sensor bars between louver blades substantially increases air velocities inside the louver. These findings suggest there is an advantage to placing the sensor bars at the louver outlet face. Keywords: ventilation; outdoor

Thole Mechanical and Nuclear Engineering Department, Solid particles, such as sand, ingested into gas turbine engines, reduce the coolant flow The Pennsylvania State University, in the turbine by blocking cooling channels in the secondary flow path. One method to University Park, PA 16802 remove solid particles from the secondary flow path is to use an inertial particle separa- tor because of its ability to incur minimal pressure losses in high flow rate applications. In this paper, an inertial separator is presented that is made up of an array of louvers Eric Grover followed by a static collector. The performance of two inertial separator configurations was measured in a unique test facility. Performance measurements included pressure Joseph Barker loss and collection efficiency for a range of Reynolds numbers and sand sizes. To comple- ment the measurements, both two-dimensional and three-dimensional computational United Technologies Corporation – results are presented for comparison. Computational predictions of pressure loss agreed Pratt & Whitney, with measurements at high Reynolds numbers, whereas predictions of sand collection East Hartford, CT 06108 efficiency for a sand size range 0–200lm agreed within 10% of experimental measure- ments over the range of Reynolds numbers. Collection efficiency values were measured to be as high as 35%, and pressure loss measurements were equivalent to less than 1% pres- sure loss in an engine application.

This theoretical investigation tested a variety of building forms and found two general guidelines that govern performance. Across all building manipulations, results showed that forms minimizing volume and RODU T maximizing southern exposure perform best. This lines with rational thought; increased volume N increases the volume of required conditioned space, while maximizing southern exposure allows I for greatest winter solar gains and daylighting. Following this study, energy analysis was given for three, previously conceived housing designs – “Slope House”, “Underground House” and “X House”. In all cases, formal design (siting, building form, orientation) were given, fixed parameters. This proved a challenge to the energy optimization of the house. For the “Slope House”, building volume opens to the west without the benefit of southern expo- sure on the open face. Passive solar gains were minimal, with excessive shading on south facing windows. The majority of glazing is to the north, which effectively cuts the building’s thermal resistance/storage without the offsetting solar gains received on southern exposures.

  • Building Applications, Opportunities and Challenges of Active Shading Systems: a State-Of-The-Art Review
    energies Review Building Applications, Opportunities and Challenges of Active Shading Systems: A State-Of-The-Art Review Joud Al Dakheel and Kheira Tabet Aoul * ID Architectural Engineering Department, United Arab Emirates University, P.O. Box 15551 Al Ain, UAE; [email protected] * Correspondence: [email protected]; Tel.: +971-566-433-648 Academic Editor: Arman Hashemi Received: 28 June 2017; Accepted: 4 August 2017; Published: 23 October 2017 Abstract: Active shading systems in buildings have emerged as a high performing shading solution that selectively and optimally controls daylight and heat gains. Active shading systems are increasingly used in buildings, due to their ability to mainly improve the building environment, reduce energy consumption and in some cases generate energy. They may be categorized into three classes: smart glazing, kinetic shading and integrated renewable energy shading. This paper reviews the current status of the different types in terms of design principle and working mechanism of the systems, performance, control strategies and building applications. Challenges, limitations and future opportunities of the systems are then discussed. The review highlights that despite its high initial cost, the electrochromic (EC) glazing is the most applied smart glazing due to the extensive use of glass in buildings under all climatic conditions. In terms of external shadings, the rotating shading type is the predominantly used one in buildings due to its low initial cost. Algae façades and folding shading systems are still emerging types, with high initial and maintenance costs and requiring specialist installers. The algae façade systems and PV integrated shading systems are a promising solution due to their dual benefits of providing shading and generating electricity.

Clayton Committee Members, Robert E. Johnson Wei Yan José L.

(December 2009) Ozan Önder Özener, B.Arch., Istanbul Technical University; M.Arch., Istanbul Technical University Chair of Advisory Committee: Dr. Mark J. Clayton This research study posits that an altered educational approach to design studio can produce future professionals who apply Building Information Modeling (BIM) in the context of Integrated Project Delivery (IPD) to execute designs faster and produce designs that have demonstrably higher performance. The combination of new technologies and social/contractual constructs represents an alternative to the established order for how to design and how to teach designers. BIM emerges as the key technology for facilitating IPD by providing consistent, computable and interoperable information essential to all AEC teams. The increasing trend of BIM adoption is an opportunity for the profession to dramatically change its processes and may potentially impact patterns of responsibility and the paradigms of design.
