          Abstract

          Buildings will generate considerable resource and energy consumption, environmental impact, and costs throughout their entire life cycle. Life cycle assessment and life cycle cost methods have become widely used building sustainability evaluation methods internationally due to their long-term comprehensive evaluation perspectives and scientific quantitative calculation methods. In response to energy consumption management issues in green buildings, a questionnaire survey was conducted to investigate the concepts of sustainable development, green environmental protection, and energy consumption management of construction enterprise personnel. Through the survey, it can be seen that corporate executives generally have a sense of sustainable development and pay more attention to sustainable competition and the green development of enterprises. Approximately 90% of executives understand energy consumption models. Only 10% of employees do not understand, but they are acquired by the company’s frontline employees. The result of the feedback is just the opposite. Frontline workers pay little attention to the long-term development of the company. Only about 5% of employees are proficient in the energy management system, but the proportion of completely unknown is as high as 20%, indicating that the overall energy management awareness of Chinese enterprises still needs to be strengthened. Secondly, through design experiments, the energy-saving management effect of the energy consumption model was observed and analyzed. From the power saving and load test, we found that the monitoring of the energy consumption model is helpful for companies to choose more energy-efficient building circuit designs, achieving an average annual energy-saving effect of about 8%, so as to achieve the purpose of energy saving.

            A MODEL OF A NEAR-ZERO ENERGY HOME (nzeh) USING PASSIVE DESIGN STRATEGIES AND PV TECHNOLOGY IN HOT CLIMATES

            INTRODUCTION Recent development has seen a drastic increase in energy use trends in Saudi Arabian buildings leading to a demand for an effective course of action for energy conservation and production. A case study-based research initiative exploring near-zero energy potential in Saudi Arabia was undertaken. A 4-bedroom detached single-family faculty residence at King Fahd University of Petroleum and Minerals (KFUPM) representing common regional housing design trends was utilized. A base case simulation model of the house was developed and validated using short-term and real-time energy consumption data. Three sets of strategies: passive design strategies, representative codes and standards, and renewable technology were employed in the new design of the house. Passive strategies comprised a green roof, a ventilated wall system, a sloped roof, and insulation for thermal bridges. These alternatives helped reduce the annual energy consumption of the house by 17.2%. The most recent version of the International Energy Conservation Code (IECC 2012) was also incorporated along with ASHRAE Standard 62.2 for ventilation. The code and standard together reduced the annual energy consumption by 31.1%. Solar PV was then utilized to reduce grid utilization for the remainder of the house energy loads. This strategy provided 24.7% of the total energy consumed annually. A combination of strategies showed a 70.7% energy consumption reduction, thereby decreasing the energy index of the house from 162.9 to 47.7 kWh/m 2 /yr. The Zero Energy Building (ZEB) concepts and strategies utilized in this study demonstrate a socially responsible approach to achieving near-zero energy performance for an existing house.
