    Energy Conscious Technology

    In the U.S buildings consume 38.5% of the nation’s primary energy, and this figure is predicted to grow to 53.5% in 2030. Commercial and residential buildings in the U.S. consume 36% of the nation’s primary energy and 71% of the nation’s electrical energy. Furthermore, U.S. buildings are responsible for 38% of the total U.S. carbon dioxide emissions, which constitutes 10% of the global carbon dioxide emissions. The U.S. building emissions are equal to the combined building emissions of Japan, France, and the U.K.

    First, in order to design and build the energy efficient building, it is necessary to save energy, especially high-rise buildings. Moreover, the evaluation and verification are made using the computer program eQUEST. It is an interactive DOE-2 windows interface program with added wizards and graphic displays to aid in the use of DOE-2. It is the newest DOE-2 building energy simulation and cost calculation engine. eQUEST and PowerDOE feature the identical DOE-2.2 simulation engine. eQUEST is the most updated building energy use simulation tool, moreover, it is free and contains a complete version DOE-2.2 and its documentation.

    The use of building energy simulation programs is now necessary to show (1) energy code compliance using the performance method and (2) energy savings relative to code for LEED certification. Computer modeling and simulation of the project is required during the schematic phase to determine optimum the envelope, systems and plant based on economic payback. Detailed simulation is required when submitting the construction documents to show code compliance. After construction and during operation, the results of the computer program building energy simulation analysis must be validated with Measurement & Verification (M&V) guidelines by the Federal Energy Management Program (USDOE).

    Second, the most green and sustainable goals can also be found in LEED, the most widely used green building rating system in the U.S. Architects, real estate professionals, facility managers, engineers, interior designers, landscape architects, construction managers, lenders and government officials all use LEED to help transform the built environment to sustainability. Therefore, everyone involved in building projects, especially architects and designers should consider that proper fenestration is key in attaining energy conservation and achieving a LEED certification.

    In sum, final objective was to establish a guideline for architects, designers and engineers to take into account the importance of energy efficient high-rise buildings. Further, the application of the above method can result in a more energy-efficient building that can assist in the certification by the LEED green building rating system. This implies that our researches can be introduced into high-performance green buildings certificated by LEED.
