The Fifth International Conference on Efficient Building Design

Materials and HVAC Equipment Technologies

Beirut, Lebanon | October 20–21, 2022



The conference, organized by ASHRAE, the ASHRAE Lebanese Chapter, the Munib and Angela Masri Institute of Energy and Natural Resources, and the Maroun Semaan Faculty of Engineering and Architecture (MSFEA) at the American University of Beirut, will take place October 20-21, 2022 at The American University of Beirut, Beirut, Lebanon.

The objective of the conference is to present advanced research targeting human wellbeing and energy through design of safe, healthy, thermally comfortable, and resilient buildings at minimal energy costs. Moreover, papers are welcome on topics that encompass sustainable HVAC solutions that can combat global warming in arid and semi-arid regions and the influence of adoption of sustainable practices by various stakeholders on the investment in decarbonization of buildings.

The focus of the 5th ASHRAE Beirut Conference is on better building design and state of art technologies in building materials and systems will greatly reduce the energy consumption and hence reduce the emission in carbon dioxide. It is of interest to present at the conference papers on design, systems, and control strategies of low energy and near zero energy buildings and prospects of next-generation sustainable HVAC systems that are dependent on renewable energy sources. Moreover, presentations on the latest developments of energy efficiency standards and other building codes including new refrigerants that are adapted to the warmer climates. 

Parallel to the conference, a number of courses will be facilitated and offered on site​ by the ASHRAE Learning Institute (ALI).

    Course Description:

    The VRF training offered by the ASHRAE Global Training Center provides in-depth training of VRF technology, including equipment and system types, heating/cooling operation, heat recovery, and the benefits of variable refrigerant flow (VRF) systems customized for the Middle East & Northern Africa practitioners. The training focuses on the VRF design process, including load profile, analysis, and ventilation air strategy.  Among other course features is a review of refrigerant piping design, unit sizing, and system monitoring/controls.

    The training covers a review of ASHRAE Standard 15 “Safety Standard for Refrigeration Systems and Designation and Classification of Refrigerants,” the industry reference to ensure the safe design, construction, installation and operation of refrigeration and air conditioning systems by establishing specific safety requirements. Applying Standard 15 to VRF systems is accomplished by reviewing three basic sorting classification: occupancy, system, and refrigerant.

    The training explains the step-by-step approach to ensure that the VRF system design follows the safety requirements of Standard 15. The course concludes with a focus on human comfort and sustainable design featuring example buildings, ventilation systems, and VRF system layouts.

     Course Topics:

    • Background of Variable Refrigerant Flow
    • VRF Technology Benefits
    • VRF System Types and Applications
    • Water-Source VRF Systems
    • Air-Source VRF Systems
    • Design Considerations
    • VRF System Design Example
    • Dedicated Outdoor Air System
    • VRF Ventilation System Design
    • VRF Design Workshop Residential Application
    • Safety Considerations for VRF Systems
    • Refrigerant Piping Design

     Course Objectives:

    • Provide overview of variable refrigerant flow (VRF) system technology, theory, and operation
    • Discuss consideration for design and application of VRF systems in buildings
    • Describe applicability of ASHRAE Standard 15, Safety Standard for Refrigeration Systems, requirements to VRF systems
    • Review application of VRF systems in different building types

    12:00 PM to 3:00 PM GST

    Course Description:

    Net zero energy buildings (NZEBs) are those which, on an annual basis, use no more energy from the utility grid than is provided by on-site renewable energy sources. These buildings use 50% to 70% less energy than comparable traditional buildings. The remaining energy use comes from renewable sources, like solar panels or wind turbines incorporated into the facility itself. The 3-hour course provides application knowledge of the design and operating principles for energy-efficient buildings and available technologies and systems to achieve NZEBs design. Building design strategies; review of current policy and regulation, energy, environmental and economic assessment of building’s performance; energy efficiency in HVAC, lighting, and appliances; and on-site renewable energy sources are topics covered.

     Course Topics:

    • Defining NZEBs
    • Why Net Zero
    • Background on CO2 and Global Warming
    • Targets for Net Zero
    • Examples and Case Studies
    • Energy Consumption
    • Design Standards and Calculations
    • NZEB Design

     Course Objectives:

    • Discuss Design Strategies to achieve NZEB
    • Discuss Design Principles of Energy Efficient Buildings
    • Describe Operating Principles of Energy Efficient Buildings
    • Describe Energy, Environmental & Economic Assessment of Building’s Performance
