HBLC
Powerful software tool for calculating heating and cooling loads for buildings. Allows the user to access complex heat-balance algorithms using a Windows interface. Geometric inputs are entered graphically using intuitive click-and-drag mouse functions and allows the user to visualize the building model as it is developed. HBLC (Heat Balance Loads Calculator) creates an input file for and runs the BLAST (Building Loads Analysis and System Thermodynamics) simulation program. After simulating, HBLC retrieves results from the simulation and can present these results in a graphical presentation. On-line helps provide valuable on-the-spot assistance that will benefit both new and experienced users. HBLC is an excellent tool which will make the process of developing BLAST input files more intuitive and efficient.
