    Inverse Design of Indoor Environment by CFD-Based Optimal Methods
    The inverse design approach is new to indoor environment research and building design community, though it has been used in other industries including automobile and airplane design. Inverse design concept uses the desired indoor environment as the design objective and inversely determines the systems required to achieve the objective. Backward methods can be used to identify contaminant sources in an enclosed environment. However, these methods cannot be used to inversely design a desired indoor environment. Forward methods, such as the computational-fluid-dynamics (CFD)-based genetic algorithm method, the CFD-based adjoint method and the CFD-based proper-orthogonal-decomposition method, show the promise in the inverse design of airflow and heat transfer in an enclosed environment.

    How to Maximize the Historical Opportunity to Improve Cooling Efficiency
    In 2016 the Kigali Amendment to the Montreal Protocol was agreed upon by 197 nations. The agreement fixed a timetable to reduce super polluting F-gases used in cooling and for the first time the door was also opened to improving cooling efficiency in tandem with the F-gas transition. How this will happen is not yet clear but efforts are already underway, in particular driven by a new philanthropically supported global initiative, the Kigali Cooling Efficiency Program (K-CEP). Working in 38 developing countries (including Lebanon), and in partnership with the UN, World Bank and other cooling experts, K-CEP’s methodology supports institutions, policies, finance and access to cooling in order to help speed and scale cooling efficiency.

    Design of Indoor Environment by Creating Shared Values
    Indoor environment affects occupants’ health, comfort and performance. Energy used for heating, cooling, ventilating and air conditioning of a building is substantial. Yet, in many buildings indoor environment is mediocre. Today ambitious energy saving goals has been adopted in many countries. In order to move closer to the goals energy saving is achieved by reduction of ventilation air supplied to spaces. However, energy saving strategy is dangerous because it will negatively affect occupants’ health.
    This talk justifies the need for improving the present air distribution design in spaces, and in general the need for a paradigm shift from the design of collective environments to the design of individually controlled environments.

    Designing for IAQ: Complying with Requirements of Standard 62.1 (MENA)

    Date: October 3, 2018
    Description: This course focuses on the basic requirements of ASHRAE Standard 62.1-2016, Ventilation for Acceptable Indoor Air Quality. The newest version of the standard includes a major change to the scope of the standard by which residential occupancies are moved from ASHRAE Standard 62.1 to 62.2. This course provides an overview of the requirements of the new standard with emphasis on changes from the previous version and practical application of the standard to modern VAV systems. New requirements to the indoor air quality procedure for determining minimum ventilation rates are discussed. In the 2016 version, changes were made in determining air class for laboratory exhaust systems and the use of sensors for demand control ventilation, and these changes are discussed as well. The course presents sample calculations for code review and for physical operation.          

    Standard 90.1: HVAC/Mechanical and Appendix G (MENA)

    Date: October 3, 2018
    Description: This course focuses on the major requirements of ASHRAE Standard 90.1-2016, including incorporated addenda. The ASHRAE Standard 90.1: HVAC/Mechanical and Appendix G (MENA) course will also cover highlights of the envelope, mechanical, HVAC, and lighting requirements in Appendix G and its new compliance path and performance rating method. Baseline building conditions and climate zone information on many cities in the region will also be provided.
