I need a complete heat-loss and heat-gain analysis for an office building of under 50,000 sq ft. All modelling must be carried out in IES VE (or software that offers equivalent dynamic thermal simulation accuracy), and the final numbers must be suitable for sizing the HVAC system and satisfying code submissions. Project is in the UK. Scope • Import my Revit model (I will supply the .rvt file and a brief schedule of constructions) and confirm geometry, orientation, and space usage. • Apply realistic envelope, infiltration, internal load and schedule data; flag any information you still need from me. • Run peak heating and cooling load calculations, then provide both whole-building and room-by-room results. • Summarise key assumptions, diversity factors, weather file used and safety margins so the engineering team can trace every figure. Deliverables 1. Native IES (or equivalent) project file. 2. PDF report with: methodology, input summary, hourly load graphs, peak design day tables and recommendations. 3. Spreadsheet export of the final sizing numbers. Acceptance I will review the model inputs and expect total heat gains and losses to balance with envelope and internal load data within ±5 % of manual check figures. Please state your experience with IES or comparable dynamic tools when you respond, along with an indicative timeline to first draft results.

Hello, I’m an HVAC engineer experienced in dynamic thermal modelling and can deliver a full heat-loss and heat-gain analysis using IES VE or equivalent high-accuracy tools. I will import your Revit model, validate geometry/orientation, and apply detailed inputs for envelope, infiltration, internal loads, and schedules aligned with UK standards. The analysis will include peak heating/cooling loads, room-by-room breakdowns, and fully traceable assumptions including weather data, diversity factors, and safety margins. Deliverables will include the native model file, a comprehensive PDF report with graphs and peak tables, and a spreadsheet of sizing results. I have performed similar simulations for office buildings to support HVAC sizing and compliance submissions. Please share the Revit model and construction data so I can begin immediately. Thanks.

Hello, I am a Senior Design Engineer with over 10 years of experience in mechanical modeling and thermal analysis. I specialize in high-precision simulations and have extensive experience working with Revit-to-Thermal models, ensuring seamless geometry and data integrity. My technical approach: 1. Model Integration: I will import your .rvt file into IES VE (or DesignBuilder/EnergyPlus for equivalent dynamic accuracy), verifying orientation, thermal zoning, and construction schedules (U-values, G-values). 2. Internal Load Modeling: Applying realistic occupancy, lighting, and equipment gain schedules, including diversity factors to prevent over-sizing. 3. Dynamic Simulation: Running hourly simulations using local UK weather files (DSY/TRY) to capture peak design days for both heating and cooling. 4. Detailed Documentation: Providing a comprehensive PDF report with hourly load graphs and a spreadsheet export, ensuring every figure is traceable for your engineering team. Acceptance Guarantee: I am committed to the ±5% accuracy threshold compared to manual checks, as I strictly follow ASHRAE and CIBSE calculation methodologies. - I am ready to start immediately. I can provide a quick "Input Verification Summary" after the first 4 hours of reviewing your Revit model free of charge. If the modeling logic meets your standards, you can award the project.
