Company Services
 

Special considerations that are inherent to mechanical and electrical design projects include precise control, a variety of physical limitations imposed by the process or building code restrictions, the need to safeguard equipment and personnel, and energy efficiency and cost effectiveness of the chosen design.  The mechanical and electrical design staff at Lindgren & Sharples, PC is comprised of experienced problem solvers who have earned our firm a reputation for being both responsive to the needs of our clients and displaying creativity in our approach to design and resolution of technical difficulties.  Our expertise encompasses new construction, as well as renovation/rehabilitation of existing facilities.  Lindgren & Sharples, PC's services include:

Energy Management Services
Demand-side management services can result in big electrical utility savings for industrial, commercial, and institutional facilities of all sizes and types.  Lindgren & Sharples, PC first collects data from the previous 12-month billing cycle for your facility, focusing on electric rates, metering arrangements, and utility rebate programs offered by your provider.  We then create an inventory and profile of all major electric loads including HVAC, lighting, and existing energy management systems.  This leads to an exploration of possible billing errors and cost savings opportunities such as:

Metering and rate change - Demand control • Off-peak usage - Operational changes - Energy storage systems - Fuel switching - Possible negotiation of a special rate contract with the utility provider

From the results of our initial findings, we can create and assist with implementation of an Electric Energy Management Program designed to maximize returns, ensure that new equipment functions properly, and help the client adapt to changes in utility policy.  Services provided in support of the electric energy management program may include:

Regular monitoring of monthly electric bills, utility rates, and electric loads. Forecasting of electric bills and selection of favorable rates when new equipment or operational changes are being evaluated. - Engineering and supervision of all Electric Energy Management Systems.

Heating, Ventilating, Air Conditioning
We provide complete HVAC system design and analysis for a broad range of projects including standard and innovative space air conditioning, central boiler plant, underground steam distribution, triwater systems, and cogeneration systems for commercial, institutional, and manufacturing facilities.  We can also retrofit existing heating/cooling systems to increase energy efficiency.

Plumbing and Process Piping
Designs for water supply and waste systems, medical gas vacuum systems, fuel distribution systems, and industrial process.

Electrical Systems
Electrical renovation and upgrade to meet current codes and standards, electrical load analysis, and load management.

Interior/Exterior Lighting
Lighting systems for numerous building types and exterior and exterior uses.  Typical interior systems utilize incandescent, fluorescent, and HID type fixtures.  Typical exterior systems include design services for streetscapes, public parks, recreational facilities, and parking lots that combine technical as well as aesthetic sensibilities.

Power
Design of electrical power factor correction systems for electrical motor installation; electrical distribution and surge protection systems for data processing equipment; and low, medium, and high voltage power distribution systems.  Design elements include switch gear, transformers, feeders, distribution panels, and metering.

Auxiliary Emergency Power Systems
Design of emergency and stand-by systems; selection of engine-generator equipment with automatic transfer mechanisms.

Data System Networks
Design of data network systems, including fiber-optic backbone (both fiber to the IDF and fiber to the workgroup/classroom) and hubs.

Temperature Control And Controls Instrumentation Systems
Design, start-up, and monitoring of complex instrumentation and electrical and pneumatic control systems (local loop and computer-based distribution) for individual and multi-use complexes and both motor and microprocessor-based controls.  Design of flow, pressure, and temperature recording and control devices.

Energy Recovery
Designs to upgrade existing HVAC systems and to maximize efficiency and control the cost of new systems.  Services may include analysis and design of central boiler plants; power factor correction systems; refrigeration, heat recovery, and air conditioning systems; under­ground steam distribution systems, waste heat recovery systems; kitchen exhaust and laundry water heat reclamation systems.

Solar Energy Systems
Feasibility studies and design of active and passive solar energy heating and cooling systems.

Energy Conservation Studies
Lindgren & Sharples, PC has prepared numerous Technical Assistance Reports under the Federal Institutional Conservation Program for schools, hospitals, and municipal buildings throughout New England.

Life Safety Communications
Fire and security alarms; fire suppression and sprinkler systems; sound and intercom systems for commercial, industrial, residential, and institutional facilities.

Acoustic Analysis
Evaluation of rotating and vibrating equipment and design of effective and affordable sound attenuation systems.

Fire Suppression
Wet pipe, dry pipe, deluge and pre-action fire sprinkler systems; standpipe system as well as special application fire suppression systems such as AFFF foam extinguishing systems, dry chemical systems and environmentally safe Halon extinguisher systems.

Our more than 35 years of engineering expertise, progressive design techniques, and the free exchange of ideas among all parties are the elements which allow Lindgren & Sharples, PC to provide the best in mechanical/electrical engineering and design for each and every client.
