 5.7.4 Solar Energy. When indicated by the `Scope," describe and evaluate solar energy
applications for space heating. The purpose of the evaluation is to determine the technical and
economic feasibility of including a solar energy system in the project.
5.7.5 Restriction on the Use of Ozone Depleting Substances (ODS). Do not specify
equipment or design for equipment which utilize Class I ODS. A list of the commonly used
Class I ODS is as follows.
Common Name
Chemical Name
Trichlorofluoromethane
CFC-11
Dichlordifluoromethane
CFC-12
Chlortrifluoromethane
CFC-13
Trichlorotrifluoroethane
CFC-113
Dichlorotetrafluoroethane
CFC-114
Chloropentafluoroethane
CFC-115
CFC-12/HFC-152a Azeotrope
R-500
HCFC-22/CFC-115 Azeotrope
R502
HFC-23/CFC-13 Azeotrope
R-503
1,1,1-Trichloroethane
Methyl Chloroform
Bromochlorodifluoromethane
Halon 1211
Bromotrifluoromethane
Halon 1301
Dibromotetrafluoroethane
Halon 2402
The A-E shall certify that neither equipment utilizing Class I ODS nor Class I ODS have been
specified in either the drawings or the specifications. (A sample form is provided in Appendix
C). If project requirements mandate the use of Class I ODS or equipment utilizing Class I ODS
(i.e., no other feasible alternative exists), the A-E shall provide to the PDE, written justification
requesting approval to use Class I ODS. The PDE will then provide guidance to the A-E
regarding the incorporation of Class I ODS and/or associated equipment in the project.
5.8 ELECTRICAL
5.8.1 Interior Distribution System. Provide the following information.
a. Electrical characteristics (phase, voltage and number of wires) of the proposed
circuits and a breakdown of the estimated connection load.
b. Lighting and convenience outlet loads.
d. Loads for special operating equipment such as compressors, generators, pumps and
for power receptacles being provided to energize special equipment. Apply an
appropriate demand factor to each to compute the total diversified demand load.
