Why do ground loops in moist soils sometimes perform better than expected? What ground loop design tactics can address building system imbalance? Engineers need to take more responsibility for their full GSHP designs, and these questions are a good place to start.
With a little guidance on ground-source heat pump design temperatures and a few rules of thumb for ground loop flow rates, most engineers are pretty comfortable designing the building side of a ground-source heat pump (GSHP) system.
This past May I wrote in the Back2Basics column about the design intent of a small city school system that chose to invest in an annual contract for a temporary air-cooled chiller for special events and emergency crisis shelter center.
Leaning on experience and data from various K-12 cities and projects, the authors pursue some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
When it comes to writing an important research paper, it’s essential to include references. That’s exactly what Tom Mangogna had his district engineering staff do when it came time to research using Daikin for their school district.
Budgets, codes, and technologies are constantly shifting and evolving. These days, even the classrooms are often portable. Staying one step ahead will depend on your knowledge of current design options and how to integrate them into the space.
Whether kids like school or not, attendance is mandatory for many years. Academic performance during this time often influences eventual jobs, income, and life satisfaction. During the formative years, parents mandate adequate sleep and good eating habits to improve their children’s concentration.
School, warehouse, office building … the boiler stories they tell put the focus back on specific circumstances and smart pre-design study to ensure their systems (and budgets) enjoy the best of times for as long as possible.
Boiler Maintenance & Lifecycle Costs; Proper upkeep can seem like a high bar, but it's nothing compared to a drain on the budget, an avoidable full replacement, or an on-site incident, read more in January issue.
