Green Isn’t Just a Buzzword

Did you know that windows can account for as much as 25 percent of energy loss in your home? That light colored materials on the external walls and roof can reduce cooling requirements by up to 15 percent? That a well-sealed thermal envelope can reduce energy costs by as much as 50 percent? We do. And we bring that knowledge to every home we build. For us, every home is a green home.

But beyond the common knowledge that can make every home greener, we also specialize in several sustainable building techniques that we can use to reduce your energy costs and your environmental footprint.

Some of the techniques we use include:

  • Solar PV
  • Solar thermal
  • Geothermal
  • Thermal envelope
  • SIPs
  • Hers score
  • High performance insulation.

We’ll help you do it right...

You may have concerns that these energy-saving options add complication to your construction job. Or that they cost more to implement than you would reap in savings. That’s not necessarily the case. We’d love to talk to you about some of the more sustainable home-building options—we think you’ll be surprised. We also have extensive experience helping our clients navigate through municipal energy requirements. If you choose to go green, we’ll help you do it right, cost-effectively and with minimal hassle.

SIP Panels

Saving Energy, Cutting Costs

Industry experts agree that ensuring a strong thermal envelope around your house is the number one way to increase energy efficiency in your home. Structural Insulated Panels (or SIPs for short) are a great way to create an effective thermal envelope. SIPs are high-performance building panels used in floors, walls and roofs.

SIPs can be made from a variety of materials, but we prefer polyurethane/closed foam SIPs for their higher R-value* per square inch, higher density for better structural value, and vapor barrier qualities.

We have a lot of experience working with SIPs and often use them to make homes more energy efficient. They are easy to install and require less labor, which saves on both construction time and cost. We work with a variety of SIPs companies in Colorado and can help you figure out which SIPs solution is right for your home.

*R-value—Indicates an insulation’s resistance to heat flow. The higher the R-value, the more effective the material is at insulating.

Boulder County

Boulder County BuildSmart.

Looking to navigate through the building process in Boulder County?

We have built homes for dozens of homeowners in Boulder County and we are extremely familiar with the ins and outs of Boulder County BuildSmart, the county’s residential green building code. These requirements affect all new residential construction and additions in unincorporated Boulder County. We have been through extensive Boulder BuildSmart training and can not only build to code specifications, but also advise clients on what they need to do to comply with BuildSmart regulations.

GEOs

Building Geosolar in Colorado.

Cornerstone Contracting has been the builder on the GEOS development in Arvada since the project’s inception. GEOS is the first sustainable, integrated community in Colorado where energy from the earth and sun replace all fossil fuels. We use a range of architectural materials—including brick, stone, and stucco—to create a variety of single-family homes, town-homes, live-work spaces, condos, and co-housing communities. Our involvement with GEOS reflects our commitment to creating sustainable communities that use zero energy to benefit our humankind and our planet.

Silo

Building Net-Zero.

Cornerstone Contracting has partnered with Cornerstone Homes Development Company to create a new net-zero energy, sustainable, urban neighborhood in Lafayette, Colorado that incorporates green building, green infrastructure, and urban agriculture. This 80 acre development will be made up of over 280 lots with diverse housing options, a centralized community center, and commercial retail space. To preserve the overall rural aesthetic, 47% of the development will consist of an extensive network of parks, pocket parks, open landscape, trail corridors, habitat, agriculture & riparian areas.
