Commercial Buildings

Picture
According to DOE, in 2005 commercial buildings used 18 percent of energy in the United States, accounting for 18 percent of greenhouse gas emissions. Cost cutting measures, government regulations (California Title 24) and climate change concerns are motivating building owners to look at energy efficiency measures. However, the task seems too daunting and building owners/managers don't know where to start the process. An EcoNexus® energy audit helps determine the energy usage pattern, conduct trend analysis and identify retrofits that give the biggest and fastest ROI. Since the audit is conducted at sub-meter level, it provides granularity to quickly determine energy efficiency problems. Granular graphical visualization of energy usage helps educate people and change behavior. A multi-tenant commercial building can now charge tenants fairly for energy usage in common areas and not based upon leased square footage. Commercial buildings can cut down cost of wasted energy and equipment maintenance. EcoNexus® real-time solution provides immediate feedback on control changes to mechanical systems. No more waiting till the end of the month for the utility bill to determine the impact of the control changes. Trend analysis helps commercial buildings can quickly determine the peak demand helps manage energy costs based upon tiered pricing or time of use pricing. Sub-meter level granular energy usage pattern helps understand energy demand and participate in Demand Response (DR) Programs. Participation in a DR program can actually become a revenue generating mechanism as well.

Section 179D of the Internal Revenue Code, created as part of the Energy Policy Act of 2005, provides a maximum deduction of $1.80 per square foot to the owners of energy-efficient commercial buildings for the year in which the qualifying property is placed in service.

Industrial Buildings

In the near future, product labels will be required to show associated carbon footprint for the product. With an integrated solution where the facilities management and manufacturing systems are integrated, all the costs savings associated with consistency, training, maintenance, operations and overhead are realized throughout the plant, site, region and enterprise. Additionally, the total cost of manufacturing can be calculated when the typical overhead expenses for energy are monitored in real-time and recorded to the historian, where information can be analyzed within contexts such as energy costs per batch, per product, per shift, normalized for square footage and degree day effects. When associated with time of day rates, product runs can now be analyzed and potentially shifted according to the most efficient and cost-effective schedule. EcoNexus® can help determine the carbon footprint.



Municipal / Government Buildings

Picture
Smart choices about energy in government buildings can set a very powerful and very public example of energy efficiency and environmental stewardship. And every dollar saved on energy costs means more government funds can be diverted to other good uses, such as education, crime prevention, or national security.

According to U.S. Department of Energy (DOE), new high-performance government buildings—designed to save energy and reduce environmental impact—can cost up to 50 percent less to operate than traditionally designed buildings. These buildings serve as showcases for energy-efficient lighting, building envelope features, and heating and cooling systems. They also incorporate the latest renewable energy systems, water conservation features, recycling and waste management systems, and use of environmentally sensitive building products and systems.

Existing government buildings offer similar opportunities for reducing operating costs and demonstrating innovative technologies. From firehouses and libraries to offices and police stations, government buildings can benefit from targeted energy improvements. Space heating, lighting, and water heating tend to consume the most energy in these buildings, and replacement of old boilers, lighting systems, and other inefficient systems can save up to 30 percent annually. EcoNexus® can help identify the most effective energy efficiency measures.

DOE's Federal Energy Management Program (FEMP) helps to reduce the cost of government by advancing energy efficiency, water conservation, and use of solar and other renewable energy technologies. FEMP provides guidelines and tools to help federal facilities save energy and money.
