Green Building & Remodeling

Green Building

The home building industry coined the phrase green building in the late 1980s, turning a niche movement of resource-efficient homes into a quiet revolution – one that is increasingly becoming a preferred way to build and remodel.

Green building means incorporating environmental considerations and resource efficiency into every step of the home building and land development process to minimize environmental impact. It’s a practical response to a variety of issues that affect all of us – like increasing energy prices, waning water resources, and changing weather patterns. It means making intentional decisions about:

  • Energy efficiency improvements such as high levels of insulation, efficient HVAC systems, high-performance windows and energy-efficient appliances and lighting

  • Water conservation measures such as water-efficient appliances and fixtures, filtration systems, and drought resistant or low-maintenance landscaping

  • Resource conservation using materials and techniques such as engineered wood and wood alternatives, recycled building materials, sustainably harvested lumber, and more durable products

  • Indoor environmental quality considerations such as effective HVAC equipment, formaldehyde-free finishes, low-allergen materials, and products with minimum off-gassing or low volatile organic compounds (VOCs)

  • Site design planning such as minimizing disruption and preserving open space

Green Product Use

Energy-efficient windows
• Energy-efficient appliances
• High-efficiency HVAC systems
• Enhanced insulation package
• Air sealing package to reduce air infiltration
• Energy-efficient lighting
• Low-flow shower heads and faucets
• Low-or no-VOC paints/sealants
• Moisture-management products and methods
• Advanced framing techniques
• Products with recycled contents
• Drought-tolerant landscaping
• Products with low off-gassing of indoor pollutants
• Low-flow toilets

Many of the same techniques and products can be used in a remodel project to increase energy efficiency, conserve water and improve indoor air quality.

HERS Rating

What is a HERS Rating?

The HERS Rating system (Home Energy Rating System Ratings) is a home energy rating and is a requirement for many green building and energy efficient building standards, and is the nation's leading set of guidelines. A HERS Rating assigns a score to the home being evaluated on a scale from 0-150, with lower numbers representing less energy consumption (a HERS score of 0 represents a "zero energy home," which produces at least as much energy as it consumes), and higher numbers representing greater energy consumption. A standard new home would receive a score of around 100, and most existing homes fall somewhere between 100 and 150.

What are the Benefits of a HERS Rating?

Having your home rated can be a great way for builders and realtors to set their homes apart in a crowded real estate market -- a good HERS score is an objective, measured representation of a home's energy efficiency.

When purchasing or building a home an energy rating allows you to compare homes in relation to their energy efficiency.

  • An energy rating is mandatory when qualifying for an energy efficient mortgage (EEM).
  • An energy rating is mandatory for a home to be labeled as ENERGY STAR.
  • Energy ratings can help qualify your home for certain utility rebates.
