Energy-efficient HVAC systems design

Although our “product” is construction drawings, our real product is our ability to design highly efficient mechanical solutions. Ideally, architects and contractors involve us early in a project, preferably in the conceptual stage. We provide valuable input on the mechanical systems and make recommendations on materials, methods, and constructability. When making recommendations, we always consider budget and schedule as well as energy efficiency.

Our team can provide as little or as much design assistance as needed. In some cases, we provide project management to guide the architect or general contractor in the integration of the mechanical and plumbing systems. For instance, for a large custom home we might coordinate the design and integration of the radiant floor distribution, domestic hot water, duct distribution and other peripheral systems such as pool/spa heating or wine storage. We can also integrate solar-thermal and heat recovery systems into domestic hot water designs. Design assistance may also include working with the project team to meet requirements for Passive House designs, Net Zero Energy Building Certification and LEED certifications.

Third Party Design Reviews and Installed System Evaluations

In addition to third party plan and peer reviews, we offer consulting services to clients who already have a system installed that is not meeting their expectations. These services may be as simple as trouble-shooting or as extensive as a full on-site system evaluation. We review building loads, construction documents, and control sequences, making site visits as needed to observe the systems in operation.  We then provide the client with a written explanation as to why their system is or is not performing as anticipated making recommendations for improvements or changes.

Narrative / Project Feasibility

If an owner is unsure about the type of HVAC system to install, or if they are unsure if their project is feasible, we can provide a narrative or project feasibility summary. Meline Engineering will conduct a preliminary engineering on your project to prepare a narrative / project feasibility summary to determine if your project is feasible, and may also compare several different HVAC system types to determine what works best for the client’s needs and desires. Considerations include location of project, cost of power, construction budget, project schedule, maintenance and building usage. In preparing the summary, we can also research the availability of utility rebates or tax incentives that might lower the cost of the installation.

Information requested to provide a detailed narrative include:

  • Owner’s project requirements

  • Site and Building Plans

  • Preferred list of HVAC systems to be discussed

  • For existing buildings, history of maintenance costs (if available)

  • Cost of energy or one year of power bills for an existing building

  • Any special considerations different from standard operating conditions
