ETI Technologies
With energy and water efficiency as top government priorities worldwide, ETI works with its clients to develop and introduce appropriate “cleantech” building products and technologies that simultaneously improve the environmental and economic performance of buildings and cities.
Covering the building cycle from project design, to "cleantech" technology solutions, to facility operations and management, ETI technologies address:
- Energy Efficiency
- Water Efficiency and Landscaping
- Sustainable Materials
- Indoor Environmental Quality
Energy Efficiency
Globally, buildings account for almost 50% of primary energy use and over 45% of the climate emissions. The industrial energy to manufacture building materials contributes between 5-15% of this.
ETI 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.
ETI'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. Systems integration delivers energy and water savings of 50-70% for negligible cost.
ETI 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.
As in the energy area, ETI uses integration techniques to reduce water consumption significantly. We expect that water will be a significant constraint on building development in the future and ETI can help developers create their projects within these constraints.
Sustainable Materials
Conventional buildings consume 30-40% of all available resources every year. Green buildings reduce resource consumption up to 70% and, when properly integrated, result in comparable costs to standard construction.
ETI recommends materials that reduce toxic emissions to the indoor air and have a reduced life cycle environmental impact.
ETI 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
The US Environmental Protection Agency listed indoor air pollution as one of the top 5 threats to peoples’ health. Superior indoor environments have been shown to increase productivity by up to 15%.
As populations urbanize, people spend more time indoors and are exposed to cooking and cigarette smoke, chemicals and biological contaminants that cause health problems, lost productivity, and a lower quality of life. The cost of personnel is roughly 100 times greater than the cost of energy or operations and maintenance. After routine maintenance, concentrations of indoor chemicals can be over 30 times higher than the levels recommended by the Greenguard Environmental Institute.
Providing a healthy, clean and productive indoor environment is the most cost-effective strategy a company can have. ETI creates healthy and productive indoor spaces that improve indoor air quality, daylighting and views, and building acoustics. By emphasizing the effective and efficient delivery of purified air and natural daylight, ETI not only reduces energy consumption and costs, but creates environments where workers are happier and more productive.
