Our Manual J/S/D HVAC design services are perfect for new construction projects, as well as retrofits and renovations. We take into account all of the relevant factors when designing an HVAC system, including the climate, the building envelope, and the specific needs of the occupants. This allows us to create a custom HVAC solution that is perfectly suited for your building’s energy and occupancy requirements. Our goal is to provide you with an HVAC system that is not only energy-efficient but also comfortable and reliable.

What are Manuals J, S, and D?

Manuals J, S, and D are a set of HVAC standards and protocols developed by the Air Conditioning Contractors of America (ACCA). These standards are used by HVAC designers and contractors to ensure that every component of an HVAC system is sized and installed correctly.

Manual J – Load Calculation

A lot of factors can affect the efficiency of a building, such as the type of insulation, the number of windows, and the orientation of the building itself. Our team at 5 Star Energy takes all of these factors into account when performing a load calculation. This ensures that the HVAC system we design is sized correctly and can meet the heating and cooling needs of the building.

Accurately sizing an HVAC system is essential for achieving optimal energy efficiency. An undersized system will have to work harder to maintain the desired temperature, which will result in higher energy bills. On the other hand, an oversized system will cycle on and off more frequently, which can shorten the lifespan of the system.

Manual S – Equipment Selection

Manual S contains a detailed set of guidelines for selecting the right HVAC equipment for a given application. After we have calculated the heating and cooling loads for your building, we will use Manual S to recommend the appropriate type and size of equipment for your space. We take into account a variety of factors when making our recommendations, including the efficiency of the equipment, noise levels, and installation requirements.

Manual D – Duct Design

Manual D covers the optimal ductwork design for a given HVAC system. After the heating and cooling load has been identified and the equipment has been selected, our team will design a ductwork system with the proper size, shape, and routing to deliver the conditioned air to the desired areas. Our goal is to identify the most efficient and effective way to distribute the air throughout the building while minimizing losses, leakage, and static pressure.

Our In-Depth Approach to Designing HVAC Systems

At 5 Star Energy, we take a comprehensive and individualized approach to HVAC design. We believe that every building is unique, and that’s why we take the time to understand the specific needs of each project. This allows us to create a custom solution that is energy-efficient, comfortable, and reliable.

We use the latest virtual modeling software to create a model of your building, which includes all of its structural components, including doors and windows. Once the virtual building is constructed, all of the relevant design parameters, such as thermal loads, insulation values, appliance loads, and human activity loads are inputted into the model. This allows us to see how the building will perform under different conditions and make necessary adjustments to the design.

Once we have calculated the ideal heating and cooling loads for the space, we’ll recommend the most appropriate type and size of HVAC equipment, and then design the perfect air duct system that will efficiently and effectively distribute the conditioned air throughout the building.
