Hotel Building Energy Efficiency: “Saving the Planet”

2019-07-29

Most hotel buildings are at the forefront of current trends, but can you imagine a hotel building that could “save the planet”? Don’t be surprised if you learn about a hotel that’s amphibious—capable of operating both on land and at sea—and that harnesses eco-friendly solar, wind, and thermal energy. Moreover, this hotel can be assembled in just three to four months. After all, this hotel project is part of a construction and disaster reduction initiative organized by the International Union of Architects.

   Most hotel buildings are at the forefront of current trends, but can you imagine that hotel architecture could actually “save the planet”? Don’t be surprised—if there were a hotel that could operate both on land and at sea, that could harness eco-friendly solar, wind, and thermal energy, and that could be assembled in just three to four months. After all, this hotel project is part of a building-and-disaster-reduction initiative organized by the International Union of Architects. Once people start massively constructing hotel projects that utilize solar, wind, and thermal energy, using hotel architecture to “save the planet” will no longer be just an empty slogan.
  Building energy efficiency is a major issue that affects both the national economy and people's livelihoods, and it constitutes an important component of energy conservation. Among various types of buildings, hotel buildings in particular should rightfully take the lead in energy conservation efforts. At the Copenhagen Climate Conference, China pledged that by 2020, its carbon dioxide emissions per unit of GDP would be reduced by 40% to 45% compared to 2005 levels. Buildings will play a key role in achieving this emission reduction target. However, the reality is that building energy consumption has been rising steadily year after year. According to China’s overall energy consumption data for 2010, among the three major high-energy-consuming sectors—industry, buildings, and transportation—building energy consumption has been steadily increasing as a share of total energy use.
  Among all types of buildings, hotel structures—being high-consumption venues—often require substantial amounts of resources and energy, while also emitting large quantities of atmospheric pollutants. As a result, hotels have become major contributors to urban energy consumption and carbon emissions. For a medium-sized, three-star hotel, annual energy consumption is roughly equivalent to 1,400 tons of coal, which translates into the emission of 4,200 tons of carbon dioxide, 70 tons of particulate matter, and 28 tons of sulfur dioxide into the atmosphere. A large-scale hotel with a building area ranging from 80,000 to 100,000 square meters consumes approximately 130,000 to 180,000 tons of standard coal annually. Energy conservation in hotel buildings is not only a necessity for environmental protection; it is also an essential requirement for hotels themselves as they strive to maximize profits.
  To achieve the goal of reducing building energy consumption, the State Council recently released the “Comprehensive Work Plan for Energy Conservation and Emission Reduction during the 12th Five-Year Plan.” This plan calls for the rational retrofitting of existing buildings, vigorous development of green and smart buildings, and maximizing energy, land, water, and material savings. As a result, many local governments have placed building energy conservation high on their agendas, making every effort to promote new building energy-saving technologies, retrofit old buildings, and even issuing direct regulations mandating the use of specific energy-saving equipment in new constructions.
  In terms of energy conservation in hotel buildings, the application of technology is proving to be crucial. As a range of energy-saving technologies—such as integrated solar building systems and air-source heat pumps—mature and become more refined domestically, an increasing number of hotels will join the ranks of those undertaking energy-efficient renovations in the future.

The entire health-check-up process was well-organized, standardized, and conducted in an orderly and efficient manner. Thanks to the strong cooperation from all departments, this health check-up event came to a successful conclusion.

August 22, 2022—Taizhou TV’s special news report on Taizhou Rishun: “Building expertise through dedication and helping enterprises accelerate their growth.” The future looks bright—Rishun team, keep up the good work!

Good news! Rishun Electric has been recognized on the national-level list. This time, all provinces collectively submitted applications to the Ministry of Industry and Information Technology for the national-level “Little Giant” enterprises specializing in niche fields and demonstrating outstanding innovation—over 50,000 companies in total. Ultimately, after rigorous review and public announcement, only slightly more than 1,500 companies were selected, yielding a success rate of just 3%. Kudos to Rishun!
