AST Technologies

AST's principal product is that of systems integration resulting from comprehensive product and services. AST's offerings cover the building cycle from project design, to key "cleantech" technologies, to facility operations and management.

With energy and water efficiency as top government priorities in China, AST works with its clients to develop and introduce key cleantech building technologies to promote superior building performance. AST's technologies address:

• Energy Efficiency
  AST maximizes cost-effective energy savings by optimizing the building envelope, lighting, equipment, HVAC and distributed energy systems, such as photovoltaics, fuel cells, and micro turbines.
• Water Efficiency and Landscaping
  AST reduces water consumption for landscaping and indoor needs using on-site water distribution systems, proper plant selection and efficient cooling towers, fixtures and irrigation technology.
• Sustainable Materials
  AST recommends materials that reduce toxic emissions to the indoor air and have a reduced life cycle environmental impact.
• Indoor Environmental Quality
  AST creates healthy, productive indoor spaces that indoor air quality; daylighting and views; building acoustics.

Energy Efficiency

Globally, buildings account for roughly 45% of primary energy use and over 40% of the climate emissions. The industrial energy to manufacture building materials contributes between 5-15% of this.

AST's projects typically save 50% energy or more--and as high as 70%--on lighting, heating, cooling and ventilation energy use. We achieve these savings by integrating technology and design across building systems in a very cost-effective manner.

Water Efficiency and Landscaping

On average, 80% of the global water supply treated for human use is consumed in buildings.

As in the energy area AST uses integration techniques to reduce water consumption significantly. We expect that water will be a significant constraint on building development in the future and AST can help developers create their projects within these constraints.

Sustainable Materials

Conventional buildings consume 30-40% of all available material resources every year. High performance green buildings focus on healthy, sustainable material choices.

AST uses a lifecycle assessment approach to evaluating materials for projects. Not only should materials perform well and look beautiful indoors, the materials we chose should leave the outdoors looking beautiful as well.

Indoor Environmental Quality

Modern air filtration techniques that use active polarization technology, rather than passive filters can deliver better air quality—capturing over 95% of the particles in the air—with 30% less energy use.

The cost of personnel is roughly 100 times greater than the cost of energy or operations and maintenance. Providing a healthy, clean and productive indoor environment is the most cost-effective strategy a company can have. As populations urbanize, people spend more time indoors, they are exposed to cooking and cigarette smoke, chemicals and biological contaminants that cause health problems, lost productivity and lower quality of life.

AST emphasizes the effective and efficient delivery of purified air and natural daylight, which not only reduces energy consumption and costs, but makes workers happier and more productive.
