Entertainment and exhibition centers are unlike any other commercial property since they have a special energy needs. High heat and electricity loads are the main key elements to face by the design engineers. By implementing renewable energy for heating, ventilating and air conditioning (HVAC) in entertainment and exhibition centers, a significant amount of energy savings can be achieved and this will also contribute in reducing gas emission. All power plants generating the electricity today produce gases and waste that have a negative impact on the environment. During the summer the demand for electricity increases dramatically because of the extensive use of HVAC systems, this increases the peak electric load, causing major problems in the national electric supply system. Acknowledging that global warming is the number one environmental threat, because of gas emission, puts a serious pressure on mankind to reduce carbon dioxide (CO2) emission to the atmosphere. High fuel prices force decision makers to adopt and encourage renewable energy resources. Implementing renewable energy might be a way to reduce the demand for electricity. In addition, most renewable energy systems are being developed in ways that reduce the need for convention fuel. This study presents a thorough review on ‘‘zero emissions’’ technologies for the built environment. The specific attention is given for subtropical climate in Australia. Both technical and economic feasibility compared to only grid connected HVAC are also discussed. This study contributes to the understanding and process development for implementing solar assisted HVAC systems in buildings in subtropical climates.
