Geothermal energy HVAC systems are cost effective, reliable, sustainable and environmentally friendly. Many property owners view it as an initial expensive investment but in reality the system is not expensive at all when one looked at the cost benefit analysis.
A geothermal system offers a cost effective solution considering the system payback period, system’s higher efficiency, operating & maintenance cost, cash flow, life-span, life cycle cost analysis and saves the world from global warming. The system payback period for geothermal is how long it takes to recoup the initial cost of an installation of a geothermal system based on the energy & maintenance cost savings versus the difference in the costs between geothermal and traditional systems. In most cases, the initial incremental cost of installing a geothermal system can be recovered with a five to seven years payback period. In some cases, the Federal/ State tax rebates, utility company’s energy rebates, etc. could cover the incremental installation cost entirely even in a year.
Geothermal systems can be used in new construction and as well as for retrofit applications for any types of residential, commercial, educational, schools, colleges, universities, industrial, and health care facilities. Any property development requiring renewable energy and or LEED credits are the ideal option of geothermal system. Geothermal systems offer an excellent approach for heating, cooling and hot water with one system as opposed to having a fuel furnace, boilers, cooling towers, chillers and a water heater. One system versus several systems requires much less maintenance cost and less energy cost. A geothermal system is easier to manage as one system as opposed to the cost of maintaining multiple systems for heating, cooling and hot water. The geothermal system eliminates the use of boilers, cooling towers, and chillers, etc. Thus, it eliminates the accidental gas explosion possibilities and outdoor noise pollution. It also cuts the carbon emission to the atmosphere and helps save the world from global warming. A few Geothermal Energy Projects were completed by our staff while affiliated with other firm.
Pristine Engineers professional staff are experienced in renewable energy geothermal system design and construction management. As a leader in the geothermal system industry, PEI offers developers and property owners geothermal due diligence/ feasibility studies, operating & maintenance cost studies, payback period analysis, and system design and construction administration services.
Harrington Elementary School Geothermal HVAC system:
Mr. Golam Mustafa, PE, the president of Pristine Engineers, Inc., was the Project Manager for Mechanical, Electrical, Plumbing, Fire Protection and Geothermal Energy HVAC System Design and Construction Administration Services for the Harrington Elementary School while affiliated with other firm. Mr. Mustafa was directly involved on the Geothermal HVAC system Feasibility Study, Design and Construction Administration for this 80,000 sq. ft. School Project, located in the Town of Lexington, Massachusetts. The HVAC system included five 1500 ft. deep Geothermal Wells, 69 water source heat pumps, 7 high efficiency Rooftop Energy Recovery Ventilators, Primary/Secondary heating/cooling pumps, kitchen Make-up air unit, VFD’s, CO2 sensors, and high efficiency DDC controls and a stand-by Boiler Plant. The Geothermal Wells are the primary energy source for schools heating/cooling (HVAC) system. The Boiler Plant was included only for stand-by operation if ever needed. The wells for the geothermal systems also provide free water to the school lawns and play-fields. Because of the highly efficient and environmental friendly geothermal energy system, the utility company NSTAR provides $254,000 energy rebate towards the 100% incremental cost for the Geothermal system Installation.
Fiske Elementary School Geothermal Energy:
As a token of the School Committee’s satisfaction on the 1st geothermal energy school designed by Mr. Golam Mustafa, the Town of Lexington awarded this 2nd project to design the same geothermal energy concept as was designed in the 1st school. Mr. Mustafa was the Project Manager for Mechanical, Electrical, Plumbing, Fire Protection and Geothermal Energy HVAC system Design and Construction Administration Services for the Fiske Elementary School while employed with another firm. He was directly involved on the Geothermal HVAC system Feasibility Design and Construction Administration for this 81,000 sq. ft. School Project, located in the Town of Lexington, Massachusetts. The HVAC system included five 1500 ft. deep Geothermal Wells, 73 water source heat pumps, 7 high efficiency Rooftop Energy Recovery Ventilators, Primary/Secondary heating/cooling pumps, kitchen Make-up air unit, VFD’s, CO2 sensors, and high efficiency DDC controls and a stand-by Boiler Plant. The Geothermal Wells are the primary energy source for the school's heating/cooling (HVAC) system. The Boiler Plant was installed as a stand-by operation if ever needed for an emergency. The wells for the geothermal system provide free water for the school's lawns and play-fields.
