🏠 Residential Energy Efficiency Assessment

The cost of maintaining an inefficient home is high, stemming from continuous thermal losses and poor material performance. Before investing in major renovations, understanding the structural weakness points of your building envelope is critical.

The Problem: Standard energy audits are often broad or expensive to execute. Homeowners need a quick, precise assessment that pinpoints why their home loses energy--is it the walls, the windows, or the roof? They require an actionable score and prioritized fix list.

The Mechanism (How It Works): This service analyzes key building envelope properties (like U-values, wall thickness, and window SHGC) to calculate a Thermal Performance Index. Our system uses three specialized tools:

  1. query_structure_thermal_score: Calculates the raw thermal index based on overall component metrics.
  2. query_orientation_bias: Adjusts the score by assessing passive solar gain/loss based on your home's cardinal orientation (e.g., South-facing vs. North-facing).
  3. query_improvement_recommendations: Takes the resulting A-E classification and provides a prioritized list of actionable upgrades, telling you exactly what to fix.

The Advantage: You receive an immediate, quantified energy rating (A-E) and a clear roadmap for improvement--a true blueprint for efficiency that prevents overspending on ineffective fixes. It connects raw structural data directly to measurable savings.

I have a 150 sqM house in the US with South-West exposure. The walls are 300mm thick, and I want to know my base thermal score.

First, run `query_structure_thermal_score` with the provided metrics. Then, use `query_orientation_bias` to factor in the South-West exposure for US climate zones. Finally, pass the resulting score and component data into `query_improvement_recommendations`.

My current rating is C (Average). I need to improve the glazing and roof. What should I do?

Use `query_improvement_recommendations`. You must input your current classification ('C') and a detailed component metrics object, specifically noting the glazing SHGC and insulation levels. The tool will provide prioritized steps.

I live in Europe. My house faces North, but I suspect the U-value for my roof is too high.

Run `query_orientation_bias` specifying 'North' and 'Europe'. Next, use `query_structure_thermal_score`, ensuring the roof U-value is accurately input. This combined data will help determine if your North exposure needs specific compensation.

The core metrics include total heated area, wall thickness, and combined U-values. The `query_structure_thermal_score` tool uses these inputs to generate the raw thermal index.
