Energy Star certified homes must be at least 30% more energy efficient than national guidelines or 15% more efficient than state guidelines, whichever is stricter. However, the process of certification requires a close co-ordination between the home owner, the builder & the energy rater.
Building science principles to get Energy Certifiedare multi faceted & home owners needs to familiarize themselves with different inter-related concepts including:
Comprehensive Thermal Enclosure System through air sealing, insulation, and high-performance windows
More energy efficient heating and cooling systems through High-efficiency systems that deliver better moisture control & improved indoor air quality
Water Management System to protect roofs, walls and foundations from water damage and reduces risk of indoor air quality problems.
Energy-Efficient Lighting and Appliances such as fans, dishwashers & air conditioning.
The actual steps to get energy certification for your home includes working closely with the builder & the energy rater from inception to completion. These steps include:
Pick a builder who has partnered with the EPA to build Energy Star certified homes
Work with the builder to choose Home Energy rater to certify your home. The home energy rater works with you & our builder to pick the appropriate architecture, appliances & features for the home.
Build constructs home based on discussions with Energy rather who performs inspections & diagnostic steps to verify the energy efficiency.
The rater completes final inspection of the house after its built & determines that all requirements have been met. If the requirements are satisfied & the home is certified, then a label is placed on the circuit breaker box of the home.
Once the home is certified, you still need to stay on top of things to keep your house energy efficient:
Use energy star certified bulbs & lighting
Use a programmable thermostat to manage your heating & cooling
Unplug electronics to reduce “vampire power” (power that is used after electronics are switched off)
Manage your automatic ventilation system
Manage your HVAC efficiency
Check if your water sump is working effectively & remove stones that may make it less efficient
