# Natural Ventilation Calculator MCP > Natural Ventilation Calculator lets you determine if a building's airflow meets health and safety codes. Input room volume and opening sizes to calculate Air Changes per Hour (ACH) rates. It also checks minimum requirements for specific uses like classrooms or kitchens, instantly verifying compliance against established standards. ## Overview - **Category:** health - **Price:** Free - **Tags:** ventilation, ach, air-quality, compliance, building-standards ## Description Designing a space means more than just making it look right; you've gotta make sure the air is clean enough to breathe. This MCP handles complex airflow math for building safety. You input basic data—like how big an inlet and outlet are, and what the total room volume is—and it calculates your precise Air Changes per Hour rate. Need to know if a lab or a classroom needs more air? It pulls the minimum requirements for that specific use type. Finally, you run a check against current safety codes to see if the space passes muster. Connecting this tool through Vinkius gives your agent access to these critical calculations without needing specialized engineering software. ## Tools ### ventilation Calculate Air Changes per Hour (ACH) ## Prompt Examples **Prompt:** ``` Calculate ACH for a room with 2m² inlet, 1.5m² outlet, and 50m³ volume. ``` **Response:** ``` The `compute_air_exchange_rate` tool would calculate the air change rate based on the most restrictive opening (1.5m²) relative to the volume. ``` **Prompt:** ``` What are the requirements for a kitchen? ``` **Response:** ``` By using `get_usage_requirements` with 'kitchen', you can find the minimum ACH threshold required for high-pollutant environments. ``` **Prompt:** ``` Is an ACH of 2.0 compliant for a classroom? ``` **Response:** ``` The `verify_ventilation_compliance` tool would compare the 2.0 ACH against the specific standard for classrooms to determine if it is safe or critical. ``` ## Capabilities ### Calculate Air Changes per Hour (ACH) Determines the actual air replacement rate by using inlet area, outlet area, and room volume measurements. ### Retrieve Usage Requirements Looks up minimum standard ACH thresholds for specific building functions, such as residential units or industrial kitchens. ### Verify Code Compliance Compares your calculated airflow rate against established safety standards to give a simple pass/fail assessment. ## Use Cases ### Designing a New School Wing The architect needs to know if the proposed classroom layout meets state standards. They ask their agent to use `ventilation.get_requirements` for 'classroom' and then run the calculated ACH through `ventilation.verify_compliance`. This confirms the design is safe before drawing up plans. ### Retrofitting a Commercial Kitchen A facilities manager needs to check if an old kitchen setup still vents correctly after renovation. They use `ventilation.compute_ach` with the new inlet/outlet dimensions and compare the result against the minimum standards found using `ventilation.get_requirements`. This determines required mechanical upgrades. ### Checking Lab Airflow A safety officer wants to verify if a biology lab has adequate air exchange for chemical storage. They feed the room volume and opening sizes into `ventilation.compute_ach`, then use `ventilation.verify_compliance` to ensure the rate exceeds critical thresholds. ### Comparing Ventilation Types An engineer is comparing natural ventilation versus forced HVAC. They calculate both scenarios using `ventilation.compute_ach` for the same room and then use `ventilation.get_requirements` to ensure *both* methods meet regulatory standards. ## Benefits - Avoids guesswork: Instead of estimating air flow, you get a precise ACH rate using the `ventilation.compute_ach` tool by providing inlet area, outlet area, and room volume. - Know the rules instantly: Don't waste time searching code books; use `ventilation.get_requirements` to pull minimum ACH thresholds for any specific environment (e.g., medical office, dining hall). - Pass or fail in seconds: The `ventilation.verify_compliance` tool takes your calculated rate and compares it against the right standards, giving you an immediate compliance answer. - Reduces physical site visits: You can model potential changes on paper and run a full compliance check without having to physically measure everything twice. - Faster design iteration: Engineers can quickly test multiple airflow scenarios using `ventilation.compute_ach` to ensure the initial concept is safe before any materials are ordered. ## How It Works The bottom line is your agent delivers a clear number and an immediate compliance verdict based on physical inputs. 1. First, you tell your agent the room's dimensions: the total volume, and the specific square footage of both the air inlet and outlet. 2. The tool then uses that data to calculate the precise Air Changes per Hour rate for the space. 3. Finally, it checks this calculated rate against known standards or specified usage rules to tell you if the ventilation is safe. ## Frequently Asked Questions **How do I use the ventilation.compute_ach tool?** You provide three numbers: the inlet area, the outlet area, and the room volume. The tool then calculates the resulting Air Changes per Hour rate for you. **What if my room is a classroom? Which tool do I use?** First, use `ventilation.get_requirements` and specify 'classroom' to see the minimum required ACH. Then, run your current airflow through `ventilation.verify_compliance` to check it against that standard. **Does ventilation.compute_ach require me to know code standards?** No. This tool only calculates the rate based on physical measurements (inlet/outlet/volume). You need `ventilation.get_requirements` if you want to know what the target standard is. **Is ventilation.verify_compliance safe for all building types?** It works for many, but you must use it with a specific room type and its corresponding minimum ACH rate—that's where `ventilation.get_requirements` comes in handy. **What happens if I give `ventilation.compute_ach` zero or negative values for the room volume?** The tool immediately throws an error stating that all physical dimensions must be positive numbers. It won't attempt a calculation with impossible geometry, protecting you from invalid outputs. **Does `ventilation.get_requirements` cover pollutant levels other than ACH?** No. This MCP focuses specifically on calculating minimum Air Changes per Hour (ACH). It provides established thresholds for ventilation rates but doesn't track specific chemical pollutants or CO2 concentrations. **Are there rate limits if I run `ventilation.verify_compliance` many times?** Vinkius manages the overall usage, and generally, you can call these tools frequently within standard use parameters. If you hit a limit, your AI client will alert you; check your dashboard for specific quotas. **Do I need to install anything special to use `ventilation.compute_ach`?** No installation is required beyond connecting your agent through an MCP-compatible client like Cursor or VS Code. Once connected, the tool appears in your available functions list. **What is ACH?** ACH stands for Air Changes per Hour, representing how many times the total volume of air in a room is replaced by fresh outdoor air in one hour. Tools available: `ventilation.compute_ach`, `ventilation.get_requirements`, `ventilation.verify_compliance`. **How do I calculate my ventilation rate?** You can use the `compute_air_exchange_rate` tool by providing the inlet area, outlet area, and the total room volume. **Can I check if my room is compliant?** Yes, use the `verify_ventilation_compliance` tool with your calculated ACH and the specific usage type of the room.
