Improved efficiency, comfort and safety for commercial and office buildings
Whatever the size or function, whether owner-occupied or part of a portfolio-owned and managed separately, ESI solutions deliver bottom-line cost savings and improve the comfort and safety of your occupants.
One of the primary challenges for commercial office properties is dealing with the variety of tenant needs. That requires flexible scheduling while maintaining optimum energy and cost efficiencies. To meet this demand, ESI has developed solutions that integrate HVAC, lighting and access control. We provide operators and management with the necessary tools to optimize energy efficiency while providing a high level of occupant flexibility and comfort.
We reduced energy costs for one ESI customer over $8,000 per week by implementing intelligent integration strategies, coupled with fault detection algorithms as part of a chiller plant optimization program.
In another case, we helped a customer retrofit a 65-year-old building that included:
- Conversion of fan systems from constant volume to variable air volume
- Motor replacement and variable frequency drive installation
- Integration of fire alarm system with zone annunciation
- Energy metering and energy analysis application for building performance benchmarking and measurement and future real-time load curtailment strategies
- Installation of weather station and coordinated unit control for hazardous airborne contaminant conditions
- VAV zone controls for remodeled floors
- Integrated access control and door monitoring system with elevator control
- Integrated video surveillance system
These strategies lowered annual energy costs by over $500,000 per year. We also brought the building up to date to retain and attract tenants and enable it to compete effectively with newer properties.
In yet another case, by retro-commissioning the mechanical and control systems of a facility, we reduced the annual energy spend for our customer by over 28 percent. We simultaneously improved comfort levels based on occupant surveys.
ESI has a proven reputation of enabling building owners to implement sustainability strategies that make facilities more marketable and improve occupant retention. We provide a range of services from the pre-construction or remodel stage through implementation and continuous commissioning. These include performance specification development, obtaining LEED credits, LEED commissioning, LEED EB credits and on-going operator training. Our LEED accredited professionals have the knowledge and experience necessary to help you make informed decisions that generate sustainable results and a realistic – and positive - financial return.
As budgets shrink, the need to maintain buildings in an energy efficient and sustainable manner remains critical to a successful bottom line. To meet this challenge, ESI offers services that can augment your staff or make up for non-existent in-house resources. Our experienced support engineers and certified energy managers provide remote and on-site support for facility operation and management. Services include monitoring and help desk functions, facility analysis and optimization services, as well as basic support programs. Our capabilities help lower your operating expenses and eliminate the need to add to your capital budget.
One ESI customer realized over $200,000 per year in avoided energy and operating costs. Our on-site and remote services supplement in-house staff, eliminating the need to increase staff in order to provide proper maintenance, optimization and support for the facility.
Education is key to efficient and sustainable building operation. Through ESU, ESI offers a variety of educational offerings to keep your building staff up to date on the latest techniques for operating buildings. |
