In provinces adopting tiered energy codes, how should homeowners pick U‑factor/ER targets cost‑effectively for 2025–2030?

To get the most value, improve the basic code a bit, focus on the parts that lose the most money, and don’t spend too much on things that won’t give you much back.
For provinces with tiered energy codes, aim for U‑factor ≤0.82 / ER ≥44 by 2030 balances energy savings, comfort, and cost. Consult an energy advisor to pick the most cost-effective windows for your home.
Homeowners should first identify which tier their project realistically fits based on envelope scope and climate zone. Then target U‑factors and ER values that hit the next tier above code but avoid overbuilding
Focus on windows and insulation where cost per kWh saved is lowest. Prioritize high impact elements (roof, walls, glazing) and use incremental upgrades to meet 2025–2030 codes without unnecessary premium materials.
Model the home to meet the lowest tier allowed, then invest in upgrades with best $/saved-energy often windows just above code-min U-factor/ER.
To pick cost-effective U-factor and Energy Rating (ER) targets in provinces with tiered energy codes, homeowners should prioritize energy modelling, understand the long-term benefit cost, and consider the trade-offs between initial investments and long-term savings
