Energy Modelling Leads to Lower Cost and More Efficient Ground Source Energy Systems

Renewable energy technologies are typically more costly to install than conventional ones. Return on Investment (ROI) is a major concern for most clients. Detailed energy simulations will lead to lower energy cost and reduce construction costs. Much of the work currently being done in the geothermal heat pump industry is to find methods and techniques to bring down construction costs, improve efficiency, or both. The following article discusses importance of energy modelling.

Cost is a Key Consideration When Considering Renewable Energy Systems

The timing of activity within a building, as well as many other factors such as building materials, lighting, and ventilation systems must all be considered when designing a ground heat exchanger (GHX); factors that “rule of thumb” designs do not consider. The following article discusses the creativity required to optimize the design of a GHX system to reduce cost.

A District Geothermal System in a “Green” Community

A community north of Vancouver has residents that are truly engaged in their desire to be “green”. A Geothermal District System that links residential, commercial, and institutional buildings together to create a sustainable system into the future is a key contributor to the goal of being “green”. Geo-Xergy has played a key role in the design and development of this district system.

Storage of Waste Energy in a Ground-Coupled Heat Exchanger (GHX) makes that Energy Available When Required

Remote communities need to import energy to sustain life – whether it’s diesel generators or refrigeration plants, excess heat is generated that is not being used or captured when it is available. But what if you could take that energy and store it in the ground for when it is required? Not only will it provide heat to the buildings, but it will also help balance your GHX for long-term viability. The following article talks about situations which have done just that.
