Mechanical
At DAE, our mechanical engineering services are grounded in precision, coordination, and real-world performance. We design systems that deliver comfort, efficiency, and code compliance—while supporting the architectural intent and project timeline. From high-performance heating and cooling systems to energy modeling and field coordination, we bring deep technical knowledge to every phase of the project, with a clear focus on outcomes that work in practice, not just on paper.
● Heating and cooling system design, including mini-splits, geothermal systems, radiant floors, and snowmelt systems.
● Manual J, S, and D calculations, preliminary HERS/ERI ratings, and energy modeling to support permitting and energy code compliance.
● Air distribution and ventilation system design, including duct layouts, fresh air, exhaust, and filtration systems.
● Mechanical layout and system design coordinated with architectural and structural drawings to ensure clean routing of utilities, equipment placement, and required penetrations.
● Detailed construction documents with specifications and coordination notes for permit applications.
● Construction-phase support including site visits, submittal reviews, and field-driven reengineering when needed.
Electrical
At DAE, our electrical engineering services are rooted in technical accuracy, thoughtful integration, and dependable execution. We design systems that address site-wide power needs, from utility service and backup generation to integrated lighting control, all while supporting architectural intent. From load calculations to solar integration, we bring discipline and precision to every stage of the project, ensuring electrical systems function as intended.
● Electrical load analysis and infrastructure review to determine service size and power distribution needs.
● Design and documentation of core electrical systems, including load letters, single-line diagrams, panel schedules, and equipment specifications to support project requirements and utility coordination.
● System design and equipment selection for generators, battery backup, and solar integration—including systems like Tesla Powerwall.
● Circuit sizing and wiring specifications for outlets, switches, and appliances.
● Coordination of power and controls with lighting design and smart home systems to support both function and aesthetics.
● Electrical plan sets and documentation prepared for municipal permitting and utility coordination.
Plumbing
DAE provides full plumbing engineering services for residential and commercial projects, delivering system designs that meet project demands and comply with local code requirements. We support every phase of the project—from early design through construction—ensuring coordinated solutions for water, waste, and gas systems that integrate seamlessly with the overall building design.
● Gas distribution, water supply and sewage waste plumbing design with an emphasis on both functionality and compliance with all required codes and regulations.
● Specification of specific equipment and recirculation lines to ensure consistent supply of hot water.
● Design of ejection pumps and basement dewatering systems for effective and efficient drainage.
● Plumbing riser diagrams for municipal permitting to streamline the approval process.
● Well water system design and Hunter curve analysis to optimize pressure, flow rate, and system sizing.
● Complete plumbing floor plans coordinated with architectural and structural documents to ensure accurate routing and system integration.
● Permit-ready plumbing engineering calculations and documentation to support local approvals and guide construction.
HERS/REScheck +Testing
We deliver HERS ratings, REScheck reports, and on-site testing to help ensure homes are designed and built to meet required energy standards.
A HERS (Home Energy Rating System) rating—based on the Energy Rating Index (ERI)—is a standardized score used to measure a home’s energy efficiency. It is often required for new construction or major renovations to demonstrate compliance with energy code requirements. REScheck is a separate compliance path that uses project-specific inputs like insulation values, window performance, and mechanical system specs to show that a home meets applicable code standards.
● Preliminary HERS/ERI ratings based on project-specific design and mechanical systems.
● Manual J, S, and D calculations to support energy modeling and permit approval.
● REScheck compliance reports based on architectural plans and local code requirements.
● Field inspections of foundation, insulation, and air sealing to confirm energy code compliance.
● Blower door and duct blaster testing to verify airtightness and ductwork performance.
● Combustion Appliance Zone (CAZ) testing for gas appliances, including carbon monoxide and spillage testing under simulated conditions.
● Certified HERS/ERI rating packages prepared for final permit submission.
Sustainable Design
DAE provides sustainable design services that support energy performance goals, permitting requirements, and long-term system efficiency. Our team evaluates project-specific opportunities for renewable energy and designs mechanical systems to integrate with solutions like geothermal heating and cooling or solar power generation. We also support energy code compliance through tools like HERS, REScheck, and Comcheck, ensuring that the design aligns with both code and performance expectations.
● Evaluation and integration of geothermal and solar energy systems based on project requirements and site conditions.
● Coordination of mechanical design with renewable energy strategies to ensure compatibility and performance.
● HERS ratings and energy modeling to support energy code compliance and system optimization.
● REScheck and Comcheck reports prepared for permit submission.
● Guidance on achieving energy efficiency standards and green building certifications.
Fire Suppression
DAE provides fire protection engineering services to help projects meet code requirements, protect occupants and property, and move smoothly through permitting. We design sprinkler systems that are fully coordinated with architectural and structural plans and meet the pressure, flow, and coverage requirements. Our work includes hydraulic calculations, backflow prevention systems, and submittal-ready documentation.
● Fire suppression design for both residential and commercial buildings to protect occupants and property.
● Design of Reduced Pressure Zone (RPZ) backflow prevention systems—used to protect the public water supply from contamination—along with application packages for local approval.
● Design of commercial kitchen fire suppression systems tailored to the specific hazards of cooking equipment and grease-producing appliances.
● Hydraulic calculations to confirm water pressure, flow rates, and system performance.
● Sprinkler head layout coordinated with ceiling plans and interior design elements.
● Fire pump design when additional pressure or flow is required by the system.
