Hot Water and Passive Lighting

I’ve been learning Revit and while a lot of companies products we intend to use use have moved on from AutoCad and Sketchup to providing BIM file, many companies still have yet to provide these files and/or are scared to proved them due potential of IP related theft. I’ve had to get very familiar with building families of the items to the manufacturer size specs and match their items finishes. At this point I’m feeling very confident that I can build out just about any simple Item I can visually see.

This weeks effort was focusing on hot water generation. Hot water and heating are 2/3rds of most traditional houses power consumption. As we cannot use geothermal in our area, we decided to use a system that originated in Japan from Sanden . Its a highly efficient Air to Air heat pump solution that uses up to 70% less power to heat water. We will then tie this system into the hydronic radiant heating system, making the building even more efficient. As per my research and a call with a Rep, we believe the unit will use about 2 KW of power daily on a yearly average to provide all of our heat and hot water needs. Using best practices, Ive located the Heat Pump in the hottest area outside of the house while protecting it slightly from the our normal rain pattern direction. It sits on a concrete pad, raising it up from ground level and will be bolted down as required in California. It was placed just outside the Machine Room with about 5 foot of insulated pipe direct into the 83 gallon stainless steel tank. So what do you think of my to spec REVIT Drawings?

The second one I worked on this week was to get all of the day time passive lighting solutions complete. The system we plan to use for the last part is from Parans and is the SP4L-8 unit. This is a 336w per day system that brings in sunlight at up to 1300 Lumens to 8 different poorly lit areas within the house such as closets, bathrooms and pantry. It uses Fiber Optic cables from the main unit to connect too convex lens spot lights mounted in the rooms. Once again the Revit files where not available, so I just created my own to spec family.
