It doesn’t matter if you’re constructing your single-family dream house or designing and building a large commercial piece of real estate — there are so many decisions that need to be made. The decisions will have important implications as to the cost, sustainability, life and comfort of the people living or working in the facility. It is vital that you choose wisely. 

The revised software, available online at no charge, adds the ability to compare projected costs and energy usage for all HVAC systems and hot water consumption in any building based on what is known before money is spent on selection of the HVAC and water heating systems, and almost all inputs may be adjusted once the design process begins. 

All of us at Radiant Professionals Alliance hope that you and your family and friends are safe and in good health. With vaccines now available, there is hope that COVID-19 cases are reduced, and things are getting better.
