HVAC

The use of high performance HVAC equipment can result in considerable energy, emissions, and cost savings (10%-40%). Whole building design coupled with an “extended comfort zone” can produce much greater savings (40%-70%). Extended comfort includes employing concepts such as providing warmer, but drier air using desiccant dehumidification in summer, or cooler air with warmer windows and warmer walls in winter. In addition, high-performance HVAC can provide increased user thermal comfort, and contribute to improved indoor environmental quality (IEQ).

HeatSpring instructors and courses are geared toward high efficiency systems and written for the leaders the industry.

Radiant Heating Case Studies: Ceiling Panels & Injection Piping

Expert instructor Dave Yates answers student questions with customer anecdotes on the Fundamentals of Radiant Heating discussion board
Student 1: I’ve seen two references in the course to “high temperature” ceiling panels needing to be at least 8 feet above the floor. Is this to prevent children from touching them, or is it to limit the heat in […]

It is a fairly common occurrence for a solar professional to hear from a potential client, “We get tons of sun,” or “Our roof faces due south,” and then […]

3 Ground Source Heat Pump (GSHP) System Design Questions

Expert Instructor Ryan Carda discusses vertical boring systems, horizontal ground loops and Energy Recovery Ventilator ducting on the IGSHPA Certified GeoExchange Designer (CGD Plus) Training discussion board…
Student 1: Would you say that the addition costs associated with vertical boring are greater than the cost of extra piping necessary for a horizontal system?

Ryan Carda: To a point – HDPE pipe itself is […]

HVAC Engineering: Chilled Floors + Humidity

On the Integrated HVAC Engineering discussion board, expert Robert Bean answers questions about chilled floors and humidity considerations and air mixing…
Student 1:  
Chilled floors seems like a great idea, and if you’re going to do a radiant system, you might as well consider cooling and heating.

The humidity, however, seems to be a big concern. Vapor barriers […]
