A recast of a presentation done for the Fairfax Chapter of Association of Energy Engineers in November of 2013. Presentation focuses on the the Advanced Energy Design Guides published by ASHRAE with association of AIA, USGBC, and IES with funding and technical support from DOE, NREL, and PNNL. In addition, the DOE Advanced Retrofit Guides are also discussed. Both sets of guides are available for download from this resource database.
This guide covers each major step in procuring a solar photovoltaic (PV) system:
- Conducting technical and financial studies
- Financing a PV system
- Project execution
- Operations and maintenance
- Assessing benefits
The guide provides information on the basic steps, key considerations, and where to go for more information. It is intended to provide an overview and some level of detail, with pointers to highly detailed information and resources.
In the cold climate of the upper Midwest, air-source VRF systems have difficulty meeting heating loads when the outdoor temperatures drop below -5ºF. Because of this difficulty during common cold spells, they are either oversized (adding to system cost) or supplemental heat is added (adding to operating cost). Cold temperatures can also cause frost issues around outdoor units, as well as compressor failure. A VRF system served by a water loop—in place of air—does not have these issues, making the technology more practical and effective in cold climates such as the upper Midwest. A water-source VRF system can be connected to a boiler and cooling tower or, for even higher performance, a ground heat exchanger.
