The ROI of Occupant Comfort


The investment return on a building retrofit implementation is typically measured by energy savings and the asset’s improved marketability through aesthetic improvements. But there’s a powerful third factor frequently overlooked in the retrofit discussion — occupant comfort.


The investment return on a building retrofit implementation is typically measured by energy savings and the asset’s improved marketability through aesthetic improvements.

But there’s a powerful third factor frequently overlooked in the retrofit discussion — occupant comfort.

No one disputes that a more comfortable building improves working, learning and living conditions. But how do you accurately measure, visualize and quantify occupant comfort? How do you understand the before-and-after comfort effects of a deep retrofit? Perhaps most important, how do you make the “comfort case” to a number crunching property owner or finance board?

Today, Envelope Analysis from Pella EFCO Commercial Solutions is the only deep retrofit decision-support service that measures, visualizes and quantifies occupant comfort with industry-accepted performance metrics. Finally, architects, facility managers and owners have the comprehensive, envelope-based view of pre- and post-retrofit performance they need to move a retrofit decision forward.

Trusted Insight

This next generation Envelope Analysis quantifies comfort through a series of measurements. Those measurements are given a functional value in terms of energy savings, cost and return on investment. The Pella EFCO Commercial Solutions’ Envelope Analysis uses widely-accepted ASHRAE (American Society of Heating, Refrigeration and Air-Conditioning Engineers) Standard 55 specification for the thermal comfort calculation.

Analysis findings may be used to adjust the thermostat settings and maintain the same level of comfort in the retrofit energy modeling. Lowering the set point by even a few degrees can greatly reduce energy use and, in turn, cost.

Results You Can See

Pella EFCO Commercial Solutions’ Envelope Analysis includes thermal modeling of interior surface temperatures before and after a retrofit. Thermal imagery and full-color cutaways visually demonstrate energy savings.

Unmatched Value

A decision to retrofit a building is a complex decision that involves many performance factors, including occupant comfort. The counsel you offer a building owner or finance board requires a thorough understanding of all investment, aesthetic and comfort considerations. Today, the Pella EFCO Commercial Solutions’ Envelope Analysis presents a truly comprehensive evaluation for a fraction of the price of a consulting engineer’s energy audit.
