I need a complete HVAC project design, fully compliant with current ASHRAE standards, for a new three-storey building. The primary targets are strong energy efficiency and overall cost-effectiveness—from equipment selection through long-term operation. You will start with accurate heat-gain/heat-loss calculations for every floor, then translate those figures into properly sized equipment and distribution networks. Where multiple system types could meet the brief (split systems, packaged units, geothermal, etc.) please compare options and justify the final pick in terms of my efficiency-and-cost priorities. Deliverables • Load calculations and summary report • Equipment schedules with model numbers and efficiency ratings • Duct and piping layout drawings in CAD (dwg) and PDF • Ventilation and fresh-air strategy to satisfy ASHRAE 62.1/62.2 • Control schematic and brief sequence of operation • Compliance sheet referencing the relevant ASHRAE sections I will supply architectural plans in DWG as soon as the project is awarded. All files must be in English and ready for permit submission.

Hi, This is Maksim. I understand you need a complete HVAC design package for a new three-storey building, fully coordinated to current ASHRAE standards with a strong emphasis on long-term energy efficiency, operational cost savings, and permit-ready technical documentation. The project requires full heating and cooling load analysis, system selection comparisons, properly sized equipment and distribution layouts, and coordinated ventilation strategies compliant with ASHRAE 62.1 and 62.2 requirements. I have 10 years of experience in building systems coordination, HVAC drafting, and mechanical design support for residential and commercial projects, including energy-conscious HVAC planning and permit-oriented documentation workflows. I can provide complete deliverables including load reports, equipment schedules, duct and piping layouts in DWG/PDF format, ventilation calculations, control schematics, sequence-of-operation notes, and ASHRAE compliance references organized for submission and contractor coordination. I focus heavily on efficient zoning, balanced airflow distribution, fresh-air integration, and practical equipment placement to optimize both occupant comfort and operational efficiency. I would be happy to review your architectural DWG files and discuss project size, occupancy type, and climate conditions so we can develop a coordinated HVAC solution that is efficient, code-compliant, and cost-effective. Best Regards

Hi, I went through your requirements and this is exactly the kind of ASHRAE compliant HVAC design work I handle for multi storey buildings. I can develop a complete engineering package including heat gain and heat loss calculations for each level, properly sized equipment selection, and optimized duct and piping layouts focused on efficiency and lifecycle cost. I will also compare system options like split, packaged, and hybrid solutions and justify the final selection based on performance, energy efficiency, and operational cost effectiveness. I’ve handled similar HVAC design documentation for permit stage submissions, I can share relevant samples once we connect on chat. Quick question: are you prioritizing lower upfront installation cost or long term energy savings when both conflict? Best Regards, Muskan

Hi, I’ve reviewed your project and understand you’re looking for a full ASHRAE-compliant HVAC design for a new three-storey building, with a strong focus on both energy efficiency and lifecycle cost. I routinely deliver load calculations, equipment schedules with model numbers/efficiency ratings, and coordinated duct/piping layouts in CAD for permit-ready packages, so your requested deliverables map cleanly to my standard workflow. I’ll begin with detailed room-by-room heat-gain/heat-loss calculations, then size and compare suitable system types (e.g., high-efficiency split systems vs. packaged or geothermal) against your efficiency and cost priorities before locking in final equipment selections. From there, I’ll develop ASHRAE 62.1/62.2-compliant ventilation strategies, control schematics with sequence of operation, and a clear compliance sheet referencing the relevant ASHRAE sections so your submission is straightforward. Once you share the DWG architectural plans, I can move quickly into calculations and CAD layouts, targeting a lean, permit-ready set with minimal back-and-forth. Do you already have any local code or utility requirements (beyond ASHRAE and standard permit needs) that I should factor into the system selection and compliance documentation? Best regards, Atik Greetings
