This software does not expire and includes free updates. All structures either lose heat in the winter time or gain heat in the summer time. This heat loss or heat gain is caused by the fact that the transfer of heat, even in a super insulated house, cannot be completely stopped. If we know how much heat is being transferred through its walls, ceilings, floors, windows and doors, ducts and through infiltration air leakage on an hourly basis, then we could calculate the precise size heater or air conditioner the house would need to maintain a comfortable temperature.

This calculation is called a load calculation. The obvious reason is to prevent installing a system that is too small to do the job. The real reason for a load calculation is to size the equipment in order to assure comfort, economy, and good indoor air quality. When heating, it is important to size the system as close to the heat loss calculation as possible to prevent 1 drafts, 2 hot and cold spots, and 3 short cycling of equipment.

When a furnace is grossly oversized, the unit will constantly shut off and on. It may satisfy the thermostat but leave other parts of the home either over or under heated thus, leaving the occupants uncomfortable. A correctly sized unit runs longer, resulting in a better distribution of air and reduced short cycling.

Short cycling also leads to higher energy costs. Build extensive libraries, or use our pre-loaded libraries. These libraries contain hundreds of building material types for building surfaces and offers the ability to create unlimited custom material types. This program can also can accommodate custom materials which can either be built as layers of components or entered with pre-engineered numbers and can be saved and reused. Easily assign air handlers as you need them. With our easy-to-use drag and drop multi-zone tree, choose to specify equipment type easily.

Each space may have its own thermostat and can be grouped with other spaces simply by dragging from one piece of equipment to another within the multi-zone tree.
