# Energy Efficiency Estimator MCP for AI Agents AI Agent Connect > Energy Efficiency Estimator MCP helps you figure out your home's energy performance and pinpoint where you're losing heat. It analyzes your building envelope to give you an A-E rating and a prioritized list of upgrades. It's perfect for anyone looking to cut costs without guessing which renovation will actually move the needle. ## Overview - **Category:** real-estate - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_qshDrJN6VA0FBNtqJKqjNhrcXoVuW45OaWOQkl1E/ai-agent-connect - **Tags:** thermal-efficiency, a-e-rating, envelope-analysis, u-value, shgc ## Description Most people want to lower their monthly utility bills, but they often don't know where to start. You might wonder if you should replace the windows, add insulation to the attic, or switch up the siding. Buying the wrong materials is a huge waste of money. This Connector lets you stop guessing by looking at the actual specs of your building's envelope. You can provide details like wall thickness and window ratings, and the system calculates a performance score for your home. It even accounts for how your house faces, because a south-facing home captures different amounts of heat than a north-facing one. Instead of just telling you that your house is drafty, it gives you a ranked list of what to fix first to get the best results. It turns raw data into a clear plan of action. You can find this tool in the Vinkius catalog, which lets you connect all your different data sources and tools in one place. It makes it easy to move from "I want to save money" to "here is exactly what I need to do." It bridges the gap between raw structural data and actionable home improvement. Instead of sifting through complex thermal physics, you get a straightforward roadmap. Whether you're a homeowner trying to save on heating or a professional looking to assess a property's green potential, this tool provides the clarity needed to make smart investments. ## Tools ### query_orientation_bias Determines how much energy a building gains or loses based on which way it faces. It helps you adjust your score for solar exposure. ### query_improvement_recommendations Provides a prioritized list of upgrades based on your current energy rating and weaknesses. It tells you exactly what to fix first. ### query_structure_thermal_score Calculates the raw thermal index for a residential building based on its components. This gives you a baseline for how well your home holds heat. ## Prompt Examples **Prompt:** ``` 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. ``` **Response:** ``` Based on your wall thickness of 300mm and the South-West orientation, here is your home's thermal profile: | Metric | Value | | :--- | :--- | | **Base Thermal Index** | 68/100 | | **Orientation Bias** | +12% Solar Gain | | **Current Rating** | B | Your home benefits significantly from passive solar gain in the afternoon. To move to an A rating, I recommend focusing on roof insulation next. ``` **Prompt:** ``` My current rating is C (Average). I need to improve the glazing and roof. What should I do? ``` **Response:** ``` Since your current rating is a C, here are the prioritized steps to improve your building envelope: 1. **Roof Insulation Upgrade**: High priority. This is your largest area of thermal loss. 2. **Window Glazing Replacement**: Medium priority. Focus on high-performance SHGC ratings. 3. **Exterior Siding Sealant**: Low priority. Good for draft reduction but lower ROI than the roof. ``` **Prompt:** ``` I live in Europe. My house faces North, but I suspect the U-value for my roof is too high. ``` **Response:** ``` I've analyzed your North-facing exposure and the reported roof U-value. * **Orientation Impact**: Your North-facing position results in a -15% passive solar gain bias. * **Thermal Analysis**: Your roof U-value is indeed significantly higher than the regional average for an efficient home. **Recommendation**: Because you lose heat to the North and have a high-loss roof, replacing the roof insulation should be your absolute first priority to stabilize your internal temperature. ``` ## Capabilities ### Calculate a thermal index Generate a baseline energy performance score for a residential building. ### Adjust for solar orientation Factor in how the building's position affects passive heat gain or loss. ### Get prioritized upgrades Receive a ranked list of specific repairs to improve energy efficiency. ### Classify energy performance Assign a standard A-E rating to a building's thermal efficiency. ### Identify structural weaknesses Pinpoint specific areas like windows or roofs that are losing the most heat. ## Use Cases ### DIY Renovation Planning A homeowner wants to know if new windows will actually lower their bill. They ask the agent to check the roof U-value and get a recommendation list. ### Property Flip Analysis An investor wants to see if a "C" rated house can hit an "A" rating. They use the tool to see the cost-effective path to improvement. ### Climate Orientation Check Someone in a cold climate wants to know if their North-facing house needs extra insulation. They use the orientation tool to see the bias. ### Real Estate Listing Prep A real estate agent wants to provide a quick energy summary for a listing. They use the Connector to generate a performance score based on building specs. ## Benefits - Stop guessing which repairs matter most by using query_improvement_recommendations to see a ranked list of fixes. - Get a clear A-E rating that makes it easy to track progress over time. - Factor in solar gain with query_orientation_bias so you don't overcompensate for a sunny side. - Identify specific issues like high U-values in the roof using query_structure_thermal_score. - Save money on renovations by focusing on the most inefficient parts of the building envelope first. ## How It Works The bottom line is you get a clear, data-driven roadmap for improving your home's energy rating without the guesswork. 1. Provide building specs like wall thickness and window U-values. 2. The Connector calculates the thermal index and adjusts for your home's orientation. 3. You get an A-E rating and a prioritized list of recommended upgrades. ## Frequently Asked Questions **Can the Energy Efficiency Estimator help me figure out which home repairs to do first?** Yes. It takes your building's current specs and gives you a prioritized list of upgrades. This helps you focus your budget on the biggest energy leaks first. **How does the Energy Efficiency Estimator handle my home's orientation?** It uses orientation bias to see how much heat your house gains or loses based on which way it faces. This ensures your energy rating is accurate for your specific lot. **What kind of data do I need to give the Energy Efficiency Estimator?** You'll need things like wall thickness, window ratings, and the overall layout of your home. The more specific you are about the building envelope, the better the A-E rating will be. **Can I use the Energy Efficiency Estimator for a house I'm looking to buy?** That's a great way to use it. You can input the specs of a property to see its energy performance and get a roadmap for what improvements would be needed to make it more efficient. **Will the Energy Efficiency Estimator give me a specific grade for my home?** Yes, it provides a classification from A to E. This gives you a clear benchmark to see where your home stands compared to standard efficiency goals. **What inputs are needed to get the initial score?** 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. **Does my home's direction matter for the score?** Yes. The `query_orientation_bias` tool accounts for passive solar gain and wind loads (e.g., South-East vs. North). This factor modifies the score to give a regionally accurate assessment. **How do I know what to fix after the rating?** After receiving your A-E classification, use the `query_improvement_recommendations` tool. It analyzes component weaknesses and provides a prioritized list of actionable upgrades (e.g., upgrading glazing or improving roof insulation).
