The buildings we hold today have to stand for the next generation

We don't build to sell. We build to steward, owning assets long enough that today’s decisions still matter decades from now. Sustainability is not a separate initiative layered onto the work. It is embedded in how we think about ownership, operations, responsibility, and long-term value.

Why long-term ownership changes the math

Most developers build with a short exit horizon in mind. That model often rewards cutting costs on the systems that matter most over time, building envelopes, mechanical infrastructure, energy performance, and operational efficiency. KIC operates on a different timeline.

When you plan to own and operate buildings for decades, every design and infrastructure decision carries long-term consequences. Better systems are not just environmentally responsible, they are operationally smarter investments.

That perspective shapes how we build, renovate, and manage our portfolio. Sustainability at KIC is not a marketing layer. It is a direct outcome of long-term stewardship.

“A lot of companies talk about green building. KIC has consistently invested in it and executed on it. It’s a core part of how we think about long-term ownership.”
JOE BIRD, SVP REAL ESTATE & CAPITAL MARKETS

How we build, renovate, and operate

Thoughtful development

New construction designed for long-term performance.

Every new project begins with a commitment to minimize environmental impact through responsible design, durable materials, and high-performance building systems. We pursue LEED Gold certification as a baseline and have helped pioneer Passive House and Cross-Laminated Timber construction within our markets.

Key practices: geothermal and solar energy systems · Cross-Laminated Timber (CLT) construction · smart HVAC controls and high-efficiency mechanical systems · triple-pane glazing and superinsulation · sustainably sourced and reclaimed materials

Responsible renovation

Extending the life of existing buildings through thoughtful reinvestment.

Many of our properties are older buildings with decades of useful life ahead of them. Rather than demolish and rebuild, we invest in deep retrofits that modernize infrastructure, improve efficiency, and reduce long-term environmental impact while preserving the integrity of the original asset.

Key practices: high-efficiency condensing boiler conversions · full LED lighting upgrades with occupancy sensors · water-saving plumbing fixture replacements · rooftop solar installations · smart digital control systems for heating and cooling.

Intentional operations

Sustainability extends beyond construction into the daily operation of our properties.

Sustainability doesn't end at construction. Across our residential and commercial portfolio, we maintain operational standards designed to reduce waste, improve efficiency, and support healthier environments for residents, tenants, and teams.

Key practices: single-stream and specialty recycling programs · Green Seal-certified cleaning products · paperless resident communication · smoke-free buildings across residential and common areas · EV charging stations and bicycle storage · environmentally responsible consumables.

Improvement: Upgrading all Heat Tape sensors​

Working with Powder Watt to install updated cameras and sensors to help only run the heat tape when necessary. This will be done in 2026 or the summer of 2027. This upgrade could cut power costs by 20-30%, even more during mild winters. Rocky Mountain Power covers 50% of the cost.

1. Retention of Embodied Carbon​

In new construction, a massive amount of energy is expended to extract, manufacture, and transport materials like concrete, steel, and glass. This is known as embodied carbon.​ By reusing an existing shell, you bypass the carbon-heavy process of demolition and new structural construction.​ It is estimated that it can take between 10 to 80 years for a new, energy-efficient building to overcome the carbon debt created during its construction.

2. Waste Reduction​

Demolition and construction debris account for a significant portion of landfill waste globally. Adaptive reuse keeps high-volume materials—such as brick, stone, and heavy timber—out of the waste stream.​

Divert Waste: Millions of tons of debris are avoided by maintaining the "bones" of a structure.​

Circular Economy: It promotes the idea of buildings as "material banks" where resources are kept in use for as long as possible.

3. Energy Performance Upgrades​

While older buildings are often perceived as "leaky" or inefficient, adaptive reuse provides an opportunity to perform deep energy retrofits.​

Thermal Mass: Many older buildings feature thick masonry walls that provide excellent thermal mass, naturally regulating internal temperatures better than thin-walled modern glass towers.​

Modern Systems: During the transition, developers can install high-efficiency HVAC, LED lighting, and smart building sensors, marrying the durability of old materials with the efficiency of modern tech

"Help save the Earth we share."
ALAN E. Lewis, FOUNDER
This phrase has been part of how the Lewis family talks about its work for forty years. It still shapes how we develop, how we renovate, how we manage every square foot under our care. The buildings we put up today will outlast all of us. We'd like them to be worth inheriting.
