Jump ducts are an increasingly popular method for improving the energy efficiency of homes with forced-air heating and cooling systems. They address the critical issues of equalizing air pressure in various parts of the home and of handling return air. Without balanced air pressure, energy efficiency decreases as conditioned air escapes through the building envelope, through unplanned routes such as leaky windows or around electric outlets.
Best Practices Guide for residential HVAC retrofits. This best practices guide for residential HVAC system retrofits is aimed at contractors who want guidance on delivering energy efficient, cost effective and innovative products.
Aerosol sealing is more effective and convenient than conventional methods for sealing ducts, because it requires less time and effort, and seals a larger portion of a leakage area more quickly.

A home energy rating involves an analysis of a home’s construction plans and onsite inspections. The HERS Index is a scoring system established by the Residential Energy Services Network (RESNET). The lower a home’s HERS Index, the more energy efficient it is in comparison to the HERS Reference Home.
REM/Rate Home Energy Rating Tool: The software calculates heating, cooling, hot water, lighting, and appliance energy loads, consumption and costs for new and existing single and multi-family homes.
REM/Design Home Energy Analysis Tool: Developed specifically with the needs of homebuilders, remodelers, energy consultants and designers in mind, REM/Design calculates heating, cooling, hot water, lights and appliance loads, consumption and costs for single and multi-family designs in over 250 North American cities.
REScheck: The REScheckTM materials have been developed to simplify and clarify code compliance with the Model Energy Code (MEC), the International Energy Conservation Code (IECC), and a number of state codes. The REScheckTM residential compliance materials offer two ways to demonstrate compliance: the trade-off approach and the prescriptive packages approach.
REScheckTM: This is a link to a recorded webinar which covered the basics of using REScheckTM and was geared toward the beginning user. The webcast included 60 minutes of instruction and software demonstration.
Blower Door Testing and ACH50: A useful, reliable diagnostic tool is available to quantify air leakiness: the blower door; sometimes called a door fan. Its application is most practical in single-family residential housing.

Resource Efficient Plumbing highlights five technologies that are easy to install, result in efficient and speedy delivery of hot and cold water, and allow for future, simplified retrofit of a greywater reuse system.
Demand (Tankless or Instantaneous) Water Heaters How they work, types and installation considerations.
The quantity and quality of light around us determine how well we see, work, and play. Light affects our health, safety, morale, comfort, and productivity. In your home, you can save energy while still maintaining good light quantity and quality.
Light Fixtures – Energy Star light fixtures
Energy Efficient Indoor Lighting
Proper lighting improves the function, appearance and energy efficiency of a home. It is also important to the occupants’ comfort, health and safety.
Outdoor Lighting Design
When designing outdoor lighting, you need to consider the purpose of the lighting along with the basic methods for achieving energy efficiency.
Energy Star Appliances
When buying an appliance, remember that it has two price tags: what you pay to take it home and what you pay for the energy and water it uses.Â ENERGY STAR qualified appliances incorporate advanced technologies that use 10-50% less energy and water than standard models.

2009 is the year companies are planning to launch wireless energy dashboards that will sit in your home, monitor energy data from your electricity meter and let you know if youâ€™re being an energy hog.
U-factor X area; REScheck performs a simple UA calculation for each building assembly to determine the overall UA of your building. The UA that would result from a building conforming to the code requirements is compared against the UA for your building. If the total heat loss (represented as a UA) through the envelope of your building does not exceed the total heat loss from the same building conforming to the code, then the software declares that you pass. A high-efficiency equipment trade-off can also be performed under certain codes.
