There do not appear to be any substantial negative impacts

resulting from the utilization of solar energy. The materials of construction exist and are commonly used by the industry at present. These include glass, thermal insulating materials, plumbing materials, working fluids, and thermostatic control systems. Application of these materials to solar energy utilization will not compete with other uses since this will supplement existing heating systems. Legal or Regulatory restrictions do not appear

to exist.

Work proposed under this subprogram should have a slight but favorable effect on employment. However, if solar heating and cooling of buildings were to achieve wide-scale acceptance and application, substantial changes in the equipment and building industries might occur.

Equipment sales of $4.5 billion are projected as possible by the year 2000. An export market may also develop although it can be expected to lag behind the domestic market.

The costs of the first solar heating and cooling systems will be greater than conventional systems but more development and the large scale production will reduce the costs.

The major capital investments necessary for implement of this R&D program are for solar collectors, energy storage, and associated

pumping and control equipment. These are above the cost of conventional HVAC systems. This project will involve buildings already in existence or planned for rehabilitation or which are planned to be built as part of Federal and private construction programs. This subprogram will be carried out on Government property when applicable or on privately owned property with federal funding of the incremental cost of the solar equipment only. No land acquisition is required. Utilization of solar energy for heating and cooling is fully compatible with some existing systems, thus, in many regions of the country hybrid systems, employing

supplementary energy sources, may be used.

With regard to the impact of these systems on the environment, the systems which we envision today cause neither atmospheric nor net thermal pollution. Moreover, no operational or health hazards are foreseen. Early units, not economically or commercially competitive, have been installed by individuals in residential communities and all regulatory requirements have been met. In the long term, the benefits to society are that it will make man almost independent of fossil fuels, thus conserving a vital resource.

The overall objective of this sub-program is demonstrate the feasibility and cost-effectiveness of systems utilizing solar energy for heating, cooling, and for meeting the hot water needs for all times of buildings in all climatic regions of the W.S.; and to make those systems comercially acceptable by F 1979. The sub-nrogram will:

To demonstration projects will be undertaken utilizing these systems in small commities. Approximately 200 structures will be utilize in the demonstration projects. The sub-corsi is essentially limited to develoning, testing and evaluating the systems. Test systems will be installed in existing or planned structures. The pilet pleat and demenstratim plant costs are caly for test and develornt evaluation and equsition and installatim the systems. The sub-program will not construct buildings for the purpose of testing these systems.

The overall objective of this sub-proman is to demonstrate the feasibility and cost-effectiveness of systems utilizing solar energy for heating, cooling, and for mating the hot water may's for all tons of buildings in all climatic regions of the U.S.; and to make these systems amrcially acontable by FY 1979.

Arcximately 25% of the nation's current consumption of energy is used for space heating, cooling, and water heating. It is estimated that by 1985 the cherry consumed by these functions will ment to 17 x 1015 ETUE. This subproman is desimed to provide an altomative am-haistable non-miluting energy sourc to perform these functions. It is estimated that ontinal svetres can provide 40-60% of a home's heating and cooling requirements. AN NOPAUSA solar energy panel, in a report dated December 1972, estimated chat to 30% of the nations's crenty requirements in these areas can be met by solar xwered systems in the year 2000.

o mejor technical barriers exist to prevent the development of practical solar povered steas. In addition, these systems are fullycompatible with some existing systems, thus, A zeny regions, hybrid systems can be used. A major emphasis of this sub-progren vill e to reduce component costs (collectors and cooling systems). Cost per MTU associated 4th these systems very from region to region. These estimates range from $1.60/MTU © $5.78X/BTC depending on the location and assumed costs of the collectors. le sub-progres vill demonstrate the performance and effectiveness of these systems in CO structures located in 15 communities around the country. Typical system costs for . single family swelling is estimated to be $5,000. Such a system will generate 58 30/yr.for en estimated 20 years.
