REScheck Form: A Guide to Residential Energy Efficiency

The REScheck form, though not a document you directly fill out yourself, plays a crucial role in ensuring your new home is built with energy efficiency in mind.  Understanding what it is and how it works empowers you to make informed decisions during the construction process.

Unpacking the Basics

The REScheck form is the output generated by REScheck software, a tool developed by the Department of Energy (DOE).  This software helps builders and designers demonstrate a residence meets the International Energy Conservation Code (IECC) or similar local energy codes.  The IECC sets minimum efficiency standards for new homes, aiming to reduce energy consumption and create a more sustainable built environment.

There are two main pathways to compliance with the IECC: prescriptive and performance.  The prescriptive approach outlines specific insulation levels, window specifications, and other building envelope requirements.  The performance path allows for more flexibility, where builders can use different materials and assemblies as long as the overall energy performance of the house meets the code requirements.  The REScheck software performs calculations to determine whether a house designed under either approach complies with the code.

What's Inside a REScheck Form?

While the specific format may vary slightly depending on the REScheck software used, a typical REScheck form will contain several key sections:

  • Project Information: This section identifies the location, size, and type of the building.

  • Climate Zone: The IECC divides the United States into different climate zones with varying heating and cooling requirements.  Knowing the climate zone is crucial for determining the appropriate energy efficiency standards.

  • Building Envelope Characteristics: This section details the insulation levels for walls, ceilings, floors, foundations, and windows.  U-factors (resistance to heat flow) and R-values (thermal resistance) are used to quantify the insulating properties of these elements.

  • HVAC System Characteristics: Information about the heating, ventilation, and air conditioning (HVAC) system is included,  such as its efficiency rating and duct leakage levels.

  • REScheck Rating: This section is the heart of the form.  It displays the calculated overall heat loss (UA) of the building and compares it to the allowable UA established by the code.  If the calculated UA is lower than the allowable UA, the design is considered compliant.

  • Additional Information:  The form may include other details relevant to the energy efficiency analysis, such as appliance assumptions and solar energy considerations.

Who Uses the REScheck Form?

The REScheck form is primarily used by building professionals like architects, builders, and energy raters.  However, homeowners can also benefit from understanding it. Here's why:

  • Informed Decision-Making:  The REScheck form provides insights into the energy efficiency strategies employed in your new home.  This allows you to discuss potential upgrades with your builder, such as improved insulation or high-performance windows, that might lead to greater energy savings and a more comfortable living environment.

  • Long-Term Cost Benefits:  Energy-efficient homes tend to have lower utility bills.  Understanding the energy performance of your house through the REScheck form can help you anticipate these cost savings.

  • Environmental Friendliness:  By promoting energy efficiency, REScheck helps reduce greenhouse gas emissions associated with residential energy use.  Knowing your home is built to these standards can provide peace of mind regarding your environmental impact.

Beyond the Form: Additional Considerations

While the REScheck form is a valuable tool, it's important to remember it's just one aspect of a comprehensive energy-efficient home strategy.  Other factors to consider include:

  • Air Sealing:  Even the most efficient insulation can be compromised by air leaks.  Proper air sealing techniques are crucial to prevent drafts and maximize energy savings.

  • Renewable Energy Integration:  Incorporating solar panels or other renewable energy sources can further reduce your reliance on traditional energy sources.

  • Appliance Efficiency:  Choosing energy-efficient appliances can significantly impact your overall energy consumption.

By working with your builder and understanding the REScheck process, you can ensure your new home is not only beautiful and functional but also built with energy efficiency in mind, leading to a comfortable, cost-effective, and environmentally friendly living space.
