Energy Engineering and Deisgn was hired by Save The Bay to Retro-Commission their two year old building. Save The Bay is a non-profit organization formed to clean up Narragansett Bay. The building was designed as a “sustainable” building with the intention of being LEED Certified. After occupation it was determined that the mechanical systems were not operating according to the design intent and the energy use was nearly four times higher than expected. EE&D stepped in and got this building back on track with 70% energy savings.

EE&D provided Commissioning and LEED certification services to the South Providence Development Corporation for the renovation of an old abandoned pencil led manufacturing building into a LEED certified office building. The building is located in the economically depressed area of South Providence, Rhode Island and is the first LEED certified building in Rhode Island.

LEED elements of the building include; photovoltaic panels, a green roof, a rainwater harvesting system, day-lighting, use of recycled materials, and a high efficiency HVAC system. The building provides an environmentally friendly office space to tenants at a 30% lower energy cost than the ASHRAE Standard 90.1 requirements.

EE&D provided construction project management services for ConEdison Solutions during the construction of a $5 million Energy Savings Performance Contract project at the Coast Guard Base in Boston. The project included the replacement of a 150 ton absorption chiller and many other smaller chiller and air conditioner systems with one central 600 ton centrifugal chiller plant to serve 4 buildings on the base. Other measures included in the project were; a lighting retrofit, installation of a new Energy Management System, replacing many air handling units, modifying ductwork, steam lines and heaters to improve the overall comfort on the base.

The project was very challenging in that the facility is an active Coast Guard base and is the Northeast headquarters for Homeland Security. During the project the Democratic National Convention for the 2004 presidential race was held in Boston, and the base was the headquarters for security for the convention.

EE&D provided Commissioning services for a $9 million Energy Savings Performance project at the JFK Library and Museum in Boston. The main focus of the project was the installation of a new chiller plant, new boilers and hot water piping to replace electric heaters, upgrade the air handling equipment, humidification and dehumidification equipment, and an upgrade to the DDC controls capable of maintaining some spaces at the strict museum requirements of the National Archives and Records Administration while providing only comfort conditions at other adjacent public areas of the building.

This project was very challenging in that neither the construction nor the commissioning could interfere with the very high profile public and political activities that took place at the facility.

EE&D was the lead project developer for ConEdison Solutions during the development of a $10 million Energy Savings Performance Contract project for the Mahopac Central School District. The project included energy savings renovations at 6 schools, the bus garage, and the District office.

• Replacement of boilers,
• Installation of a new Energy Management Systems,
• Upgrades to the HVAC systems,
• Window replacements
• Building envelope improvements
• Improvements to the schools indoor air quality through the installation of Dedicated Outdoor Air Systems.
• Installation of solar PV, domestic hot water, and thermal systems

EE&D provided commissioning services to Western Massachusetts Electric Company as part of the verification process of the installation of a new, complex-wide Energy Management System at the STCC business park.

The facility is part of the original Springfield Armory established in 1794 by George Washington. Some of the buildings date back to the early 1800's. The HVAC system was installed in the early 1970's to provide heating and cooling for large open spaces used for electronics equipment manufacturing. Since that time the facility has been renovated several times to it's current use as primarily office space. However, the HVAC system remains essentially the same as it was in the 1970's. The challenge for the controls designer and contractor was to provide a new DDC system that would control this HVAC system to serve the diverse needs of the current tenants.

The commissioning process consisted of; reviewing the as-built documentation to determine if it met the design intent, data logging HVAC system operation, correction of operating parameters, repair of faulty HVAC equipment, use of the DDC system to provide trending, adjustment of operating parameters to optimize operation, training of facility staff, and documentation of final set points and operating parameters for future use.

EE&D provided commissioning and performance verification services to Keefe Technical School during and after the construction of a $7.5 million Energy Savings Performance Contract project. The primary scope of work included the replacement of the old chiller and air handling units, installation of a new Energy Management System, the installation of a micro turbine cogeneration unit and a dedicated natatorium air conditioning system for the pool area. The project resulted in more than 45% energy savings for the school and significantly increased comfort levels.

EE&D provided Commissioning services to the Massachusetts Department of Correction at the Norfolk Correctional complex during the construction of an $18.5 million Energy Savings Performance project. The project included more than 20 measures at 5 sites comprising more than 60 buildings totaling more than 1.4 million square feet.

• Lighting upgrades
• Complex wide Energy Management and Control System
• Replacement of two 1,500 horsepower steam plants.
• Steam Trap Upgrades
• Installation of two 600 kW cogeneration units
• Water conservation measures
• Window replacements
• Installation of premium efficiency motors<
• Installation of Variable Speed Drives
