Ground Source Heat Pump Systems (Geothermal)
Based on the Site geologic properties, ENGEO can develop Ground Heat Exchange (GHX) thermal parameters for use in Ground Source Heat Pump (GSHP) design, or can offer turnkey GSHP design, installation, and development of a financial delivery model for monetizing the energy efficiency savings to the developer. A GSHP system can be readily integrated with complementary technology (e.g. wind, solar, CHP, heat recovery) to form an important part of your energy efficiency and renewable energy solutions to meet sustainability targets. As project planning progresses into architectural design, we can meet with you, your architect, and your MEP designer to further assess and maximize energy saving opportunities and efficiencies.
As part of the feasibility assessment, ENGEO will assess the viability of open and closed loop Ground Heat Exchange (GHX) systems relevant to the optimal GSHP system on your site. Considerations include:
- Thermal properties of soil, bedrock and groundwater conditions
- Access to a high yielding, available and reliable groundwater aquifer
- Access to an available and reliable surface water source
- Required site work to reduce the cost of installation of a GHX
ENGEO employs International Ground Source Heat Pump Association (IGSHPA) accredited GSHP installers and designers, to ensure that best practices and the latest approaches are utilized, to maximize efficiency and deliver a sustainable system.
For existing systems, ENGEO is adept with proven abilities to trouble-shoot under-performing systems, identifying through forensic analysis how to best optimize system designs to heat and cool with greater efficiency and reduced cost.
ENGEO offers aerial photography through the use of an un-manned aerial vehicle (UAV). We can produce seamless digital orthophoto mosaics of entire areas as oblique or vertical photographs. We have the ability to produce digital terrain models (DTM) and produce high quality contours where we can generate ground cross section profiles. We can then use these models to design rockfall protection measures, assess rockfall volumes, model slope stability and a host of other applications. Our software can generate point clouds to be used in conjunction with our AutoCAD software where measurements can be obtained and final design drawings produced.
In addition to these high-end modelling capabilities, we are also able to produce high resolution video or photography in order to record conditions on a slope to allow for assessment of changes that occur over time as part of a geological hazard monitoring program or simply for construction monitoring.
Groundwater & Resource Management
ENGEO provides a comprehensive range of groundwater services to civil, industrial, land development, energy, and agricultural sectors. We have local industry leaders in field investigation and complex analysis tools, backed by a strong practical understanding of the groundwater science and issues in New Zealand.
Our services are focused in three main areas:
- Groundwater supply and management projects;
- Groundwater impact assessments; and
- Regulatory approvals.
Our groundwater services are delivered by professionals with specific local and international experience of numerical groundwater modelling (including FEFLOW and MODFLOW), analytical groundwater analysis, aquifer test pump program design and analysis, detailed groundwater site investigations (including geophysical investigation and interpretation) GIS analysis and policy and regulatory affairs.
Groundwater Resource Management
- Numerical groundwater flow modelling in FEFLOW and MODFLOW;
- Site investigations including aquifer test pump and geophysical program design and analysis;
- Detailed analytical analysis of site investigation data;
- Regulatory approvals for groundwater consents;
- Groundwater resource assessments for site and catchment-scale projects.
Ground Heat Exchange Systems
Ground Source Heat Pump (GSHP) systems are an established technology increasingly used as a major energy efficiency solution for new buildings and as the major components of District Energy Systems (DES) for larger developments.
A GSHP system allows thermal energy to be obtained from the ground beneath a site, using the strata and groundwater as a heat source or heat sink on a seasonal basis. And a well-designed and operated GSHP system provides building heating and / or cooling extremely efficiently, thereby reducing carbon emissions and making significant savings on operational expenditure against conventional heating and cooling technology.
GSHP systems are considered to be low or zero carbon technologies, which reduce reliance on traditional energy sources and form part of a raft of carbon reduction measures that ensure sustainable objectives are achieved. GSHP systems have been successfully developed in the US, Scandinavia and other parts of the world since the 1970s.
ENGEO is capable of undertaking a full range of services for GSHP and District Energy integrated energy efficiency projects, including:
- Feasibility study;
- Site investigation;
- Detailed system design;
- System integration and commissioning, including BMS programming; and
- Long-term maintenance.
In addition to a full range of engineering services, ENGEO is fully capable to supply the following construction management services to our clients.
- Conducting tendering process
