“…e "LEED" standard evaluation system in the United States has been widely recognized in the construction industry worldwide and has become an important standard for global green building certification. LEED certification levels from low to high are certification level, silver level, gold level, and platinum level, of which 6 major scoring systems are sustainable site, energy and atmosphere, water efficiency, construction materials and resources, indoor environment, and innovation design [18,19]. In addition, the more wellknown green building evaluation systems in the world include BREEAM in the United Kingdom, CASBE in Japan, and Blue Angel in Germany.…”

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.

Two attics were constructed as part of a building renovation project at the University of West Florida. The first attic is described as a traditional ventilated attic, with openings in the soffits and a small dormer vent on the roof. The second attic is described as a sealed attic (with no ventilation), and open-cell spray foam insulation installed on the underside of the roof deck. The study was undertaken to demonstrate hypothesized performance differences between attic types. Thermal and relative humidity sensors were installed to measure the condition of the air in the two attics spaces, and measurements were taken at 15 minute intervals. Measurements of relative humidity were later calculated as dew point and specific humidity. Similar studies are often conducted by comparison of attics in separate buildings under different use conditions. This project offers a unique opportunity to explore data collected from a single structure, and provides support for existing research on attic design in southern regions. The resultant data show significant differences in attic temperatures, with the sealed attic exhibiting a much more thermally stable pattern. There were also significant differences in attic dew points and specific humidity, although these differences appear to be much less pronounced. Data were analyzed using independent t-tests to establish significant differences between means. Overall, the sealed attic performed better than the ventilated attic, although dew point and specific humidity remain concerns.
