Central Plants

Goss Engineering prides itself in our central energy plant master planning, design, feasibility studies, and construction management experience and capabilities.

Central energy plants typically produce heating, cooling, and/or electrical power for multiple building complexes. Central energy plants achieve efficiencies that cannot be obtained in local systems, because of the energy sources used, the type of equipment utilized, and the savings in operation and maintenance through centralization and scale of equipment. Many central energy plants achieve savings by using energy, which would ordinarily be wasted in the generation of electric power, to heat and cool buildings (also known as cogeneration). Some central plants also incorporate concepts like thermal energy storage (TES) to store heating and/or cooling from lower cost energy sources or time periods.

By leveraging our extensive central plant expertise we can help you analyze the best solution to meet your current or future heating, cooling, and electrical needs in an efficient and cost effective manner.

Thermal Energy Storage Systems

Goss Engineering has extensive experience in the planning, design, and construction management Thermal Energy Storage (TES) systems.

TES is a way of producing cooling (or heating) at one point in time and using at another. Common TES systems include the storage of chilled water or hot water in a tank.

With a properly designed thermal energy storage system, Goss Engineering can help you:

      • Reduce Equipment Size (Chillers, Cooling Towers, and Pumps)
      • Reduce Overall Energy Consumption
      • Lower Energy Costs
      • Reduce Maintenance Costs

TES systems are generally either full storage or partial storage systems. TES systems gain their major economic advantage from the difference between on-peak (daytime) and off-peak (night-time) electric energy rates and demand charges. Since electricity is the primary energy source often used for cooling, chilled water TES is more common than hot water TES (heating is generally fueled by natural gas, which is not subject to time-of-use price differentials).

Full storage systems provide all the cooling from the TES system during a certain part of the day (generally on-peak hours) with cooling equipment shut off. During other hours, the cooling equipment is operating at higher load than required to meet the instantaneous load, with the cooling surplus stored.

Partial storage systems typically operate chillers at a constant rate over the full day. Peak loads are met utilizing a mix of stored cooling plus instantaneous chiller produced cooling. During lighter loads, the excess capacity from the chiller is stored.

Though full storage systems can achieve greater energy cost savings than partial storage systems, the amount of cooling equipment and TES capacity (and thus the capital cost) is generally greater with full storage systems than with a partial storage system.

Distribution Systems

(Chilled Water, Heating Water, Steam, Natural Gas, etc.)

With our knowledge and expertise in distribution systems, Goss Engineering can help you plan, design, and construct a reliable, cost effective, efficient, distribution system.

Hydronic distribution systems typically consist of closed-loop pumping systems and piping networks that distribute and return chilled water, heating-hot-water, and/or High-temperature-heating-water from a central source to the end user. GEI also has expertise in steam distribution systems, domestic water distribution systems, and fuel distribution systems including natural gas.

We use a variety of computer modeling programs to optimize your facility’s expansion. After we have modeled your existing distribution system, GEI recommends taking field measurements (flow and pressure) to calibrate the computer model. With a calibrated computer model, GEI can model different distribution system expansion options with confidence.

GEI can perform life-cycle-cost analysis to determine the most economical option.

Laboratory buildings have one of the most intense mechanical systems of almost any type of building with the mechanical system compromising approximately 35% of the total building cost. There are also major safety, health and state and federal requirements to address in the planning, design and construction (or remodel) of a laboratory building.

Goss Engineering understands these requirements and has extensive experience adhering to regulatory requirements and creating a safe and healthy work environment.

Whether you want to plan, to design, or to commission a new laboratory or retrofit an existing laboratory, GEI can help.

Heating, Ventilation and Air Conditioning (HVAC)

Heating, Ventilation, and Air Conditioning (HVAC) HVAC describes systems that provide heating, cooling, and proper ventilation to a building. HVAC systems come in a wide variety of sizes, types, efficiencies, and fuel sources. HVAC systems can be a simple one-room dedicated direct-expansion unit, or a complex system of chillers, boilers, piping, air handling units, ductwork, and controls.

Proper HVAC design, construction, and operation are key in providing for building occupant health, comfort, and productivity. Goss Engineering has vast experience in the planning, design, and construction management of economical, effective, and energy efficient systems to meet your HVAC needs.

We perform feasibility studies that develop a number of technically feasible options to meet your HVAC needs. For each option, we can estimate the budget construction costs and the annual energy and maintenance costs. With this information, life-cycle-cost analysis can be performed to determine the system with the best lifetime economics.

Given the HVAC of choice, Goss Engineering can design your HVAC system for either public or private bid.

GeoThermal Energy Utilization

Properly designed geothermal energy utilization can be a cost effective and environmentally friendly solution for your heating and energy needs.

Geothermal energy utilization consists of using underground heat sources as an energy source. This typically involves drawing water from a geothermal heat source and passing it through a heat exchanger in order to transfer heat to a secondary heating system. Sometimes the geothermal water is used directly. When a hot enough heat source is available, steam can be produced in order to generate electric power.

Goss Engineering has experience providing geothermal energy utilization for several clients including a tomato grower in Bend Oregon. GEI was able to assist them in creating a system that uses ‘free’ heat from the groundwater to keep their greenhouses warm throughout the winter.

Let Goss Engineering help you determine if geothermal energy utilization can work for you.

Control Systems

Central plants, cogeneration systems, thermal energy storage systems, distribution systems, laboratories, HVAC systems, and geothermal energy utilization all require proper control in order to function as designed. Temperatures, pressures, flow rates, and levels, for example, must be monitored and controlled. Operators need to know of any emergency conditions (i.e., alarms).

Goss Engineering has the expertise to develop a state-of-the-art control system that will meet your automation needs.
