Plan Review

Constructing a new home can be stressful. From selecting a contractor to picking the finishes. Viridiant can make the process a little easier by providing impartial, third-party recommendations.


The renovation of a home presents a unique opportunity to make energy and water efficiency improvements. Often these improvements can also have a positive impact on the comfort and functionality of the home. Issues like hot/cold rooms, long wait times for hot water, and drafty spaces can be addressed, while also reducing utility bills.

Viridiant will work with you to identify options for improvements that best fit your home and your goals.

HVAC Load Sizing

As homes continue to be insulated and air sealed better, properly sizing HVAC systems becomes increasingly important.

Viridiant can perform Manual Js (HVAC sizing calculations) for new and existing homes, providing you with an accurate, impartial assessment of a home’s heating, cooling, and airflow needs. Additionally, we can perform Manual S (system selection) and Manual D (duct design).
