There must be away of making some basic assumptions to revise/adjust the DD component, unless there is a software calculator that can compute the degree days for just the period of operation. If there is such a calculator, does anyone know where to find it?
Problem: Bldg has toilet room exhaust fans operating 24 hrs per day year round. We will be time clocking the fans to run only 8 hours per day instead of 24 hours per day, and to have the fans run only 5 days per week instead of 7 days per week. What is the energy savings of not having to...
The reason for inquiring about the efficiency of the proposed absorption machine is thatthe existing machine, which it would replace, is a direct fired NG machine. Therefore, although the waste heat is free, there will be a capital expenditure for the purchasing of a new absorption machine that...
We have a 600 kW NG CoGen plant and all heat produced (H2O and exhaust) is wasted. We also run a NG direct fired absorption unit for chilled water. We are looking into the feasibility of retiring the existing unit and installing another absorption unit that can run off of the waste heat. Does...
Does anybody know of a manufacturer of stucco finished metal panels that could be used on the exterior of a self-storage building? These could be either insulated or just a plain panel. Thanks
Is there a code that prevents chillers and boilers from being located in the same mechanical room? if so, does anyone know when this went into effect? Is there any boiler or chiller size that triggers the code? And, why is there such a code, if it exists. Thanks!

I am just starting to investigate the collapse of a distribution center with 30' high tilt-up panels that used K-series OWJ for the roof framing. The collapse oocurred during torrential rains (4"/hr), and the structure was only 4 years old. The roof pitched towards the parapet formed by the...
