Q2 (a) Select Energy Conservation Measures (ECMS) from Table Q2 (a) to get the saving results as required by the saving criteria of the organisation, also taking into account the investment criteria of the organization. Justify the choice (s). (2 marks) (b) Set up the implementation plan for the selected ECMs in Q2 (a) by taking ito account the resource requirement, saving criteria and investment criteria of the organization (3 marks) (c) An energy audit was conducted in one of the lecture halls in UTHM and found excessive ventilation air has been provided. This results in higher amount of energy consumption in the air-conditioning system. Based on the audit data provided in Table Q2 (C), evaluate: Amount of excess air provided for ventilation; (ii) Possible amount of electrical energy reduction. Psychrometric chait is provided in Figure Q2 (c); and (111) Total cost saving in a year if the building operates 300 days/year and 8 hours/day if the amount of excess air avoided.
