Washington Iowa City, IA. 52240 Dear Council Members: '-Cl MAY 919 D 77 D ABBIE STOLFUS ?'dli Y CLEM I would like to take this opportunity to express rgy opinion concerning the recent issue of leashing and/or confining cats to their owner's property. Where do these people get off thinking their cats have the right to use neighbors' flower beds as litter boxes and our yards as hunting grounds! Last year my husband and I were witnesses to a very upsetting scene which tool: place in our fenced -in backyard. Our next door neighbor had three cats which she often let out any time of the day or night to roam the neighborhood. while working out in our yard one afternoon, we heard the desperate cry of a robin trying to free one of its ,young from the clenches of a cat. Before we were able to reach the scene, the cat jumped our fence with the baby robin in its mouth and then jumped into an open window of our next door neighbor's house. iiy husband went immediately to inform our neighbor lady of this incident and while giving an account of what took place, he watched the cat devour the young robin on the couch in her living room, ileedless to say, we called the Animal Shelter personnel and they promptly came out and informed this neighbor that she would have to confine her cats to her own back yard by means of leashing or caging. This, however, was never carried out. Instead this neighbor had the audacity to inform us how cruel we were to have reported her to the Animal Shelter. Since the rgysterious disappearance of one of this neighbor's cats last fall, she has chosen to keep her cats indoors. 1!e have another family on our street that bragns to everyone how their cat can survive for days on its own while it is out rnarinn the neinhbnr- hood. !•!e have chased this cat many titres from our hncl:yard and out of the neighbors' flower beds. Are we to report th^sp people to the Animal Shelter or do we take ratters into our own hands? We find it very frustrating to attempt to attract Lirds to our back vard only to have them killed by cats. Consequently, rqy husband and I no longer care whether we remain on good terms or not with thn neighbors who shoe disres9eet f— niir nronerty by allnrinn thnir not(s) to rnam the nei ghborhood.

Washington Iowa City, IA 52240 Dear Mayor Neuhauser: Enclosed you will find a recently completed report from the Iowa Public Interest Research Group, entitled "Energy Waste and Energy Conservation: A Study of Commercial Energy Use in Iowa City." The report summarizes a survey of 29 commercial and public buildings con- ducted in February to determine what energy conservation measures have been adopted in the commercial sector, and to what degree they have been effective. This survey was intended, in part, to supplement an earlier report which was submitted to the City Manager in March. In that report, Iowa Public Interest Research Group indicated that only 31% of 92 potential energy conservation measures had been undertaken by the City of Iowa City. We also suggested that many additional measures could be undertaken at little or no cost which would result in savings of both energy and money in City operations. As the earlier report was based upon a written questionnaire, its conclusions needed to be checked by actual measurements. Thus, the Iowa City Civic Center was included among the buildings surveyed in "Project Wastehunt." Among our findings: 1. Lighting levels of 48 footcandles in non -work areas, 56 footcandles in work areas, and up to 125 footcandles at work stations. (Compare these with recommended levels, Table IV of the report.) 2. Heating levels of 73-74 degrees Fahrenheit. 3. The Civic Center had slightly over 50% of the energy conserving features considered in the survey. In Short, the Civic Center appeared to be over -heated and over -lighted, and reasonable efforts seem to have been made to save energy in the building's operation. However, the energy waste involved in continuing excesses and inefficiency should concern the City Council: it represents a squandering of limited national resources, and an unnecessary cost to the City. 7n response te, the "EncrEy Use :n LDcal Goverrament," tht City of Coralville recently undertook planning to implement all feasible con- servation measures.

Fully 30% of our energy use is pure waste." John Sawhill, former Administrator Federal Energy Administration New York Times, Oct. 7, 1974 There is an energy shortage and, until alternate means of energy production are developed fully, it is here to stay. Many say the solution to the energy shortage is to take the controls off energy companies so that more energy may be produced (thereby using our already scarce natural resources even faster). But there are many more people who believe the answer is through conservation of energy and its efficient use. It is a fact that the cutback in our wasteful use of energy will change our lifestyle little, if any. Energy used to produce lighting consumed 5% of the nation's energy in 1972, 20% of all the electricity generated. Commercial, public and indus- trial buildings account for about 70% of this amount. Lighting conserva- tion practices could save up to 50% of this energy, or a savings of 2k% of the nation's total energy production. Of the energy consumed in the US, 16% is used to heat and cool commercial and industrial buildings alone. In many cases a drop of 1 degree in the thermostat setting for the heat or a rise of 1 degree in the cooling set- ting can result in energy savings of 3%. A change in the percentage of outside air that is circulated through the building will also make a big change in the amount of energy used for heating and cooling. These simple measures could result in substantial fuel savings. Fur those who don't find energy conservation for Its own sake a big enough incentive the above figures readily indicate that fuel conservation is also economically sensible. With the increasing cost of energy, conservation measures can and so save much money. This is rbc second part of a three pari report un energy conservction and usage practices in the Iowa City/Coralville area. Part one reported on energy use in local government. This second part deals with energy usage in commercial and public buildings. The third part, now underway, concerns itself with energy use in the home. The energy audit staff would like to thank those local officials and merchants who have cooperated in num study. i"cthodoln.r,y '1'be 4datac Ih`nt survey was desiLncd to identify Onerp,y use in commercial and public �uilding:� in the Iowa City-CnralVilie arca. Iowa plltC volunteers conducted the survey during the last two weeks of February to dctcrmi.ne what energy conscrva- ti.on moasures have been adopted in the commercial sector and to what degree Choy have been effective. A total of 29buildings were selected on t1w basis of their size, age, and tuneL'on. In order to provide a wide represontat: ion of buildings, four or five selections were made from each of si:; categories: 1. Shopping Center 2. Downtown Arca 7. Single Building -small area 4. Single Building -large area 5. Schools (pub! -.c primary and secondary) 6. Public Buildings (federal, state, local government) The survey was divided into two parts, a "walk-through" inspection of the designated buildings, and a more detailed questionnaire provided to the building manager or other representative. During the "walk-through" survey, background information about the building was obtained. Volunteers recorded t=perature and light levels to see if they are in compliance with federal standards. A dry bulb thermometer was used to obtain daytime temperature readings. Temperature standards were hosed on President Carter's proposed 65 degree during the day and 55 degrees at ni;;bt, and higher readings were considered to be excessive. Lighting levels were determined by light meter readings, recorded in footcandles, and evaluated in terms of Federal Energy Administration recommendations (see hesults section). Inquiries were made about the use of lighting at night or other times when the building was not in use. Additional inspection was made of heating, cooling, and ventilation practices in the buildings, checking for such features as weather-stripping, thermopane glass and hot water use. The second part of the survey sought more details regarding current energy •,raetices and conservation measures undertaken recently or currently planned. :t consisted of 14 yes or no questions dealing with heating and cooling systems, insulation, lighting practices, and actual fuel use figures. ;;us,nesses were also asked if they have recci.ved any information on energy conservation from the govern.nent. A two-week time limit was set !or completion and return of the surveys. ,tot all of the yuc:aionnui.res (Purl 2) were nice ivcd from establishments rurve.yea; and occasi.uully i.tN:.iS io Pa:� uc conn]oced. Survey results have been tabulated accordingly. Of the 29 public and coav,.crcial buildings visited, eleven are evaluated utiliv.inl; only part 1 of the survey (the wa'.V-tllrou101 report). Purthormore, only those quest:uus in the surly aosw,�r F.d pc'�;•:v, i•, or nU!'atiyely hclvc been used to tabulate the results. Questions notanswerod, considered not appitcaotc, or unrecorded are .excluded. Results With the limitations indicated below, table I shows the per cent of energy conservation measures, listed in Part I and II of the Waste Hunt Survey, adopted by the 29 public and commercial buildings visited. Table I shows that the majority (52%) of the 29 public and commercial buildings surveyed adopted between 26 and 50% of the potential energy conservation measures. Forty-one per cent ( 12 out of 29) adopted between 51 and 75% of these measures, while 7% adopted 0 to 25% of the potential energy savings measures. None of the 29 establishments attained 75 to 100% of the measures.

The survey also attempted to assess future energy conservation plans by asking "What, if any, additional conservation measures will you put into effect within the next six months?" Of the respondents only 28% (5 out of 18) were planning additional measures such as insulation of business and storage rooms, additional lowering of lighting levels, and increased use of flourescent lighting. Table II shows the type of response to the questions regarding energy conservation measures that would require no financial expenditure to implement (eg. turning down thermostats, turning off lights inside and out when not needed, unblocking air vents and ducts, etc.). Of the total number of these possible cost-free energy conservation measures, it was found that the mean percentage of measures adopted was 51%, while 49% were not employed by the public and commercial establishments.

Whereas Table II indicates the manner in which energy conservation is achieved at low or no cost, Graph III reveals the potential resources for such information and the underutilizution of these resources. 0 0 Graph III indicates the response of those surveyed when asked if they had received energy conservation information relating to commercial and public buildings from the federal, state or local government after October, 1973. Of all respondents, 72 to 78% stated they received no information from any of the three government sources. Of the small per cent indicating such information was received, only 11% of this information contained spec- ific energy conservation recommendations applicable to commercial and public buildings GRAPH III Government As A Source of Information For Commercial Businesses and Public Facilities 1001 - Percent of Commercial 6 - Public Establishments 50% - Surveyed - 0% Federal State Local No information received Only general information Specific information Table IV shows that of the twenty-nine commercial and public buildings, % or 10%shad room temperature levels at or below the FEA and President Carter's recommended standards of 62-65 degrees Fahrenheit for the day time in work, non -work and specific usage areas and 55 degrees for nightime levels. Twenty-seven per cent (7 out of 27) of those buildings exceeding these expcctstions did, however, have room temperature levels below the FEA day- time temperature level of 68 degrees. The percentage of the excess of room temperature levels among the buildings surveyed was found to be 10.71 for non -work areas, 29% for work areas, and 16% for work stations. Table IV also reveals that illumination levels in the buildings surveyed exceeded the Federal Energy Administration's recommended maximum levels by the wean average of 1611 in work arcus, 200% in non -work, and 80% in work stations. Artifical lighting was uacd in 38% (8 out of 21) of the builu.ngs during periods when natural bur.i.ght .ould have L,,cn su?fI_cient for adrquate illuminati.nn, In 171 (5 out. of 29) of the survoyed buildings supplemnntal lighting such as desk lamps was utilized to reduce unnecessary overhead lighting. Conclusion As a result of our study, it is apparent that the majority of the buildings surveyed have undertaken some type of energy conservation measures. llowever, we feel that further measures could be implemented at little or no cost to the establishment with changes resulting in immediate and future energy savings. These include such practices as closing windows and doors while a heating/air conditioning --ystem is in use, turning off lights when leaving a room, lowering thermostats in non -work areas and keeping the ventilators free of obstructions. The largest energy savings in a building can be achieved through day to day operations. Thirty to fifty percent can be saved in buildings now standing and fifty to eighty percent can be saved in new buildings planned for the future. These include the use of efficient furnaces and air conditioners along with the use of more sophisticatid technologies, such as solar devices, heat pumps and total energy systems. Presently, all incentives are geared towards keeping the initial cost down, but employing those practices with a moderate initial expenditure would lead to a substantial energy savings in the long run. In the areas of heating and lighting, our data indicates a blatant waste of energy. Heating levels exceeded up to 29% in the areas studied, and the illumination levels exceeded FEA levels by up to 200%, in the areas studied. Keeping up with the servicing of heating systems can save up to 10-20 percent of the fuel needed. As heating equipment is oftem inefficient when run at less than full capacity it is often desirable to install standby equipment when the load is less than normal. Insulation standards could save up to 80 percent of the total fuel cost along with redesigning furnaces and all heating system ducts. Lighting uses almost one quarter of all electricity sold in the United States. The current lighting standards according to some studies, as much as two times higher than required for optimal performanee.2 Lighting seldom focuses solely on the work area, resulting in the use of unnecessary energy. Reducing the level in buildings and changing to more efficient bulbs can reduce the need for heating and cooling systems along with the initial cost of installation. According to our survey there have been limited attempts to curb this energy waste. Little use o: supplemental or natural lighting (ie. sunlight, desk lamps) was found in place of artif ical or overhead lighting. The responsibility for energy conservation is often left in the building owners' hands. It was found in our results that between 72-78 percent of the commercial businesses received no information on energy saving from the federal, state or 'Local offices. The managers and other eulplov,ws are even leis aware of what :s needed in regard to euerry consorvution: Lite owner has seemingly not passed on the small amount of information he has received to his workers. In most cases, the building manager did 0 0 In Part II (Questionnaire section) of the survey, several questions concerning fuel cost and usage were included. Eighty-nine per cent of the managers or delegated representatives either did not know or did not have access to these figures. Of the 18 Part II questionnaires returned, 2 or 11% quoted some cost figures or savings. only one of the 29 respondents reported a 1-10% cutback in enerby consumption at any time during the period of January 1976 through January 1977, although the figures regarding fuel usage to support this were not available.

There is definitely a need for more information and planning if the are to be any major gains in energy conservation in commercial buildings. We have begun to control the waste of energy, but if it is to work, we need a full scale conservation program. At the present time, the United States uses about one third of all energy on heat, cooling and lighting homes and commercial buildings. An ASFPAE ()unerican Society of Heating, Refrigeration and Air/Conditioning Engineers) document, entitled "Energy Conservation in New Building Design", shows that the implementation of ASIME Standards could save 9 to 15 percent on energy bills in residential areas and between 30 to 45 percent savings in commercial buildings. The study also gives standards for construction costs, national energy consumption, building consumption and all their required structural alterations. It is estimated that four percent of the nation's annual consumption can be s9ved by 1980 and up to 12 percent by 1990 if these standards are employed. According to the Waste Hunt survey, there are few plans for any type of energy conservation programs during the next six months. If the commercial sector is to save energy, business and government must be made aware of conservation methods. Federal, state, and local governments must undertake more anpressive educational campaigns. City government should assume leadership in educating all sectors of their communities in energy conservation. The private sector, too, should disseminate information and sponsor workshops to inform businesses. Chambers of Commerce would be appropriate sponsors for community energy conservation campaigns, in cooperation with the US Department of Commerce, the Iowa Energy Policy Council, local governments, and exemplary industries or businesses. The bibliography which follows is intended as a starting point for those businesses and individuals who wish to undertake energy conservation programs.

City Engineer Iowa City Civic Center Iowa City, Iowa 52240 Subject; Iowa City Civic Center Air Conditioning Study Project No. 4476 Dear Gene: Please find attached the report of our study of comparative air conditioning systems that were considered as solutions to the currently inadequate HVAC system for the Civic Center. As has been discussed a number of times we have tried to objectively evaluate a number of alternatives and consider those things that would provide the most appropiate solution to the problems at hand. I realize that there will be a diversity of opinions amongst not only the City Council but of the local citizenry concerning how best the problem at hand may be solved. However, our, study is based upon our experience and the experience of outside con- sultants which we frequently call upon and exchange technical information with and our intent is to provide the most credible information for your use in evaluating the resolution of your present heating -air conditioning problems. As is stated in the report the data presented and the comparisons drawn can at best be considered only that; i.e. comparisons and the use of the data as absolutes for establishing enact operating and owning budgets must be tempered with known "real" conditions that the study (computer analysis) is not sensitive to. We do feel however that the results that we have presented to you are fairly realistic and as credible as we could possibly make them. We have appreciated the opportunity to serve you and apologize for the delay in getting the information correslated and back to you which has been due only to the tremendous work load that we have had over the last two to three months.

Bingham, P. E. mea IOWA CITY CIVIC CENTER AIR CONDITION ING41TUDY A study has been undertaken to investigate the problems with the existing heating -ventilating -air conditioning (HVAC) system in the Iowa City Civic Center. The building has been analyzed to determine the heat gain and heat loss for the structure and the required air conditioning to adequately serve the occupied spaces. A number of problems with the existing system have been identified and were previously reported in a letter report from Larry R. Moore on August 16, 1976. Briefly, the problems which have been identified are the existing absoption chillers have reached their end -of -life and now are becoming expensive to operate and maintain, as well as being rather inefficient. There is an apparent shortage of nominal refrigeration equipment to adequately air condition the spaces. Furthermore, there are numerous temperature control zones which have conflicting conditioning equipment since fin tube radiation is often heating while the air conditioning system is simultaneously cooling the area, resulting in expensive operation. There are also some zones that are not adequately heated or cooled at various times of the year. The system temperature controls are misapplied because of problems inherent in the basic system design. The results of the study are briefly summarized as follows. There indeed must be something done to correct the existing system as it now exists. The least cost approach to resolving the problem will be to make some extensive changes to the existing system to hopefully alleviate some of the functional problems and correspondingly provide fairly decent comfort conditions in the building. It is estimated that this effort would cost upwards to some $60,000.00. Of the four systems studied it appeared that the replacement of the existing system with a constant volume roof top single zone system would be the least first cost system, costing approximately $65,000.00. The system having the apparently lowest operating cost is system type A4, variable air volume roof top system, when the operating costs are evaluated through a 15 year period. The best investment system when considering initial cost, operating costs, and return on investment is system 04 when only these criteria are considered. The least energy consuming system is system $3, water to air heat pump with solar assist heating, followed by system #1, same as 03 with no solar assistance. When the more subjective and technical - non economical criteria are considered, system 81 appears to be the best all around system for the Civic Center. It is therefore the resultant recommendation that the best corrective effort for the appropriate heating and air conditioning of the Civic Center would be a water to air heat pump system. Solar assist heating can be added at a later date when equipment costs are less if such is desired. (1) 0 0 There are a few items which must be kept in mind as the aforementioned conclusions are considered by the building owner and a final decision is made pertaining to which of the systems studied should'be designed and prepared for installation in the building. These items include the requirement for an increased electrical service to be provided for the building no matter which system is installed, the existing system is extremely uneconomical to operate and provides unsatisfactory L - condition and will continue to be an increasing problem in the building operation, and a variety of special interest influences will undoubtedly be submitted to those reviewing the report and there will be others who may submit their own new conclusions. The aforementioned symptons relate to a number of problems, none of which -are clearly separable -and solvable without affecting..the overall HVAC system. It has been determined through our investi- gation that the existing variable air volume (VAV) boxes are bypass type wherein air is bypassed into the ceiling space whenever the room thermostat is not calling for cooling. Since the ceiling space is a return plenum with return grilles opening directly thereto the bypassed air can, without resistance, fall through return grilles into another space which may not be calling for cooling at a specific time. A second problem is that even though the automatic temperature controls on the main air handling systems are intended to provide 100% outside air ventilation capabilities whenever the outside air temperature is low enough to justify such, the outside air louver is grossly undersized (approximately 90% undersized) and will not permit adequate amounts of outside air to be drawn in to the system whenever there is a call for any quantity greater than minimum outside air. Correspond- ingly, there is no provision in the HVAC system for the ventilation air to be relieved, which results in the fans possibly operating unstably due to the increased positive pressure being developed in the building. A third and obvious problem is that the existing absorption chillers are now in a failing condition and the economics of maintaining them do not exist. Operating economies likewise do not exist at this time. Furthermore, the reliability of the absorption chillers has apparently become rather questionable. The study was extended to investigate solutions to the aforementioned problems, including the investigation of alternative tNAC systems which would address the problem of providing appropriate environ- mental control in the building, in addition to economies in operation and maintemanoe.. 7. ocnnputez progreT. we.' vc+eZ to investigate the comparative economics and energy consumptions of four candidate (2) 0 0 systems for the building. In addition the present system operating costs and comparable economies of retaining the existing system was likewise investigated and compared with the four systems analyzed in the computer study. It should be pointed out that the results of the study are based upon analytical models utilizing the best current technology and information that could be gathered together and may not exactly duplicate real operating conditions but do provide very credible results for comparative purposes. The systems which were studied are as follows: #1. Ceiling and console type water to air heat pump units using natural gas fired boilers to provide makeup heat energy. #2 A single zone constant volume roof top system using natural gas for heat and electric air conditioning for cooling. #3 The same system as that listed in item #1 with the addition of supplemental solar heat to provide makeup heat energy. #4 A roof top variable air volume system using natural gas fired boilers for heat energy and an electrically driven air cooled water chiller to provide cooling. #5 The existing system, which is a problematic VAV system with natural gas fired boilers providing supplemental heat and natural gas absorption air conditioning and some additional electric air conditioning systems providing cooling. In addition to the economics and energy consumption criteria used in drawing conclusions in this study a number of more subjective but technical criteria were incorporated in the considerations of candidate systems. These items are as follows: A. The system should provide individualized room or zone temperature control. B. It is desirable to have the capability to condition individual rooms during off -hour cycles without having to operate the entire system to provide minimal occupation zone comfort. C. The level of expertise or capability required to maintain and service this system is desired to be minimal to eliminate the need for a highly trained technician to be continuously avail- able to service the system. D. The system should have the ability to incorporate alternative energy supply sources to the highest degree posL:.ble.

As a point of reference the "rates" information used in this study agrees rather favorably with other studies completed by the author for the Corps of Engineers U. S. Air Force medical facilities, publicly owned medical facilities, and numerous similar building types investigated by both Trane Company through their TRACE program and the SEE program as completed by Mr. William S. Flemming who provides the computer analysis service for Singer Company. There is a list of definitions and nomenclature included which delineates the terminology that is incorporated in the tabulated summary of results of the study. The reader is referred to that listing of nomenclature to assist in reviewing the tabulated data. The results of the study provide rather intersting result as can be seen on the summary sheet. The least energy consuming system is system #3 @ 643,927 MBH/year, followed by system #1 @ 748,094 MBH/year. The existing system is the most consuming @ 3,009,573 BMH/ year. The best first cost system, wherein best is equated to lowest cost, is system #2 the single zone roof top system the installed cost for which is estimated to be $65,350.00. It is felt that this system is not a truly viable candidate since the entire building would have to be operated as a single temperature zone which would provide no individual or group room control whatsoever. The system with the best operating cost per year is the VAV system which would be a refinement of the existing system. The major draw- back with the VAV system is that it requires extensive duct work to be located in the building ceiling spaces. This is similar to the presently existing system. The existing limited ceiling spaces definitely influence the adequacy of air distribution throughout the building. This system, generally speaking, would have to be operated continuously to allow any individual room to receive comfort conditioning at any time during the day or night. The best system in terms of total expenditures, both for first cost, operating cost, maintenance cost, etc. is likewise system 04, VAV system. The total expenditure at the ned of the 15 year period for system #4 is $241,376.00 as noted on the data sheet. However, it is pointed out that this system does not lend itslef as well to the adaptation of alternative energy sources for heating purposes as does system $1. The system shall also be equipped with "economizer" cycles to provide the economics stated in the comparative data. The inclusion of such will require some building modifications. The present worth comparisons incorporate system #1, the water to air heat puiW ryrf n, as the basic for corTarison. F.11 numbers in that portion of the data sheet are referenced to system 01. It is pointed out that in the comparative present worth data a negative number indicates (5) 0 0 that the base system; i.e. the water to air heat pump system is the better system. A positive number suggests that the system compared to the base systems i. e. systems #2, #3, #4 or #5 is the better system. system #5 or leaving the existing system as is with no modification at all provides the greatest amount of money saved over system #1 in first year costs at an estimated amount of $73,816.00. As has been previously stated this is not an acceptable solution and correspondingly even though system #2 provides a $15,999.00 advantage over system #1 the lack of room temperature control negates its attractiveness. The system at the end of a 15 year period which provides the greatest dollar saved compared to system #1 is likewise the existing system which assumes that that system must continue to operate at present .,economies". The system which provides the best minimum return on investment as compared to system #1 is system #4 which provides an approximately $1,200.00 return in the 12th year after the system is installed. Year twelve is also the year when major central equipment for this system may need replacement and as a point of interest system #1 has been a better economic investment up to year 12. System #3 appears to, at some longer period of time (greater than 30 years for which the data was tabulated) may have a break even point and return on investment but the time period to reach such as was indicated is greater than 30 years and correspondingly was not considered viable at the current utility rates. A change in utility rates and reduced cost of solar equipment would substantially alter this comparison, however. As a result of the economics comparisons and energy consumption data the leaving of the existing system with no attention at all is the least first cost alternative. System #4 appears to have the least operating cost based upon the present and projected utility rates. The best all around system, based only upon economics, operating and comparative present worth comparisons is system #4 beyond a 12 year period. System #3 is the least energy consuming of those studies. The best system when initial cost, operating costs, maintenance costs, return on investments and flexibility of system operation plus adaptation of alternative energy sources for heating, whether immediately or at some future date, system #1 is the best solution. It is our recommendation that the owner strongly consider the installa- tion of a water to air heat pump system in the Civic Center. It should be pointed out that this same system can be rather easily extended to other areas of the total Civic Center, including the Police Station and Fire Station, while providing the same economics of operation and maintenance. Likewise, this system can very easily have added to it a water storage basin and solar collecter panels which would provide makeup heat energy in lieu of the gas fired boilers which would initially be incorporated in the system. The VAV system which requires a central air cooled water chiller does not as readily lend itself to the incorporation of an alternative energy source. (6) For your information the water to air heat pump system consists of unitized fan coil units which are located either as console units in the occupied space or as horizontal units located in the ceiling space. All of the units have their own compressors and are interconnected in a common water loop which loop has water continuously circulating throug8 it the temperature of which varies anywhere between 600 F and g0 F. Each unit can operate individually and separately from the other units and the only central plant components which must operate continuously are the circulating pumps. In addition to the individual zone units and the circulating water loop there is a closed circuit evaporative cooling tower through which excess heat energy that cannot be used for heating purposes at some other point in the building by a corresponding heat pump is released from the system. When all units are providing heating and there is not sufficient excess heat energy in the closed water loop makeup energy is provided by some alternative energy source which for the Civic Center would initially be gas fired boilers which are now existing and in the future could be warm water heated by solar panels mounted on the roof of the building. The water as it passes through the closed loop provides heat energy to individual units providing heating to a given space or likewise provides a place for excess heat energy to be dissipated whenever units are providing cooling in an occupied space. Therefore, energy is transported from one portion of the building to another for use as required in individual zones. This operation provides a great deal of diversity in system operation. The systems have been used extensively in many areas of the United States and Canada and have proven to be very attractive in operating economics, as well as attractive in first costs considerations. The systems also provide a great deal of zone flexibility and are rather easily maintained. More recent installations of such systems include the heating -air conditioning system for Plaza Center I located in Iowa City and Cedar Towers located in Cedar Rapids. There are numberous such installations in Minneapolis -St. Paul, Minneasota, Columbus, Ohio, Toronto, Canada. The system used in many of the buildings at Expo '74 in Montreal. There are a number of such systems in office buildings, schools and corrective institutions in the inter- mountain Northwest. (This information is provided not as a sales gimmick but only reference information for the reader of this report.) As a result of the comparisons completed with respect to the pre- viously described criteria the conclusions which have been drawn are presented for consideration by the reader for use in selecting alternatives to the existing heating -air conditioning problems in the Civic Center. /7) IOWAgY CIVIC CENTER AIR CONDITION39STUDY TABULATED UMMARY OF RESULTS OF SYSTEMS CO ARISONS Summary of Economic Data Installed Cost $ 81,500 System 1 System 2 System 3 System 4 System 5 System Data 65,250 97,100 91,776 <66,600 operating Cost -year 1 8,375.54 Tons Cooling (1) 32.95 32.95 32.95 27.24 37.0 Tons(5) 24,830.28 21,747.21 46,567.92 Maint.

The location of a parking ramp will have a critical effect on both new and existing downtown business. The optimal position of a ramp, in our opinion, would be the north-east area of the super block, bordered by Capitol, Burlington and Washington Streets. This location would service new mall businesses as well as existing downtown core businesses and would enjoy the support of both new and existing businesses. As an Iowa City Staff report of December 1973 clearly indicates, parking needs to be "conveniently located approximately 300, to 900' from intended uses". As distance increases, potential users decrease drastically. This report states that, "shoppers are not willing to wal k distances beyond 600, to 8001". A Donald Zuchelli report of April 8, indicates that we can anticipate removal of 760 parking spaces from the downtown core area. A new parking ramp must substitute for these lost spaces. Considering the intense use of the present Washington Street lot, it is obvious that parking in this area is crucial. Frgarding of flip ramp, it is pssr- sial to minimize the amount of time from beginning construction to completion. A ramp similar to the Carver Pavillion can be assembled quickly and economically. r1 Y1 1 i5)) AME STOLFUS CITY CLERK e 1031 In summary, we are happy to see some results about to take place in a long and frustrating urban renewal struggle. We stress the importance of parking location as an integral part of the overall urban renewal and, in fact, Iowa City scheme. Let's continue to work together to make Iowa City an even finer place in which to live and work. Thank you.
