Ice Rink Design.pdf

INTERNATIONAL ICE HOCKEY FEDERATIONYou can build an ice rink everywhere Chapter 1 1.1 Introduction of the Manual / IIHF Prototype A covered ice rink is not an impossible dream. How can it be? After all, there are over 2700 rinks in Canada alone! There are rinks in countries and cities, which never have had snow or ice. This manual from the International Ice Hockey Federation intends to show that building an ice rink is possible anywhere in the world. The basic element is enthusiasm and some entrepreneurship. We want to target ice hockey clubs and leisure organisations that have the ambition to take their program to another level and show them how to successfully construct, manage and operate an ice rink. This manual also targets the decision makers, politicians in the communities and municipalities and presents them with ideas how to make building an ice rink financially feasible. The local rink is far from only being a place where you practise and play ice hockey. Special social patterns can develop within the confines of an ice rink, and there are many ”rink rats“ who have spent long hours at the rink without ever lacing a pair of skates. Parents who assist their children, volunteers who sell hot dogs during a weekend junior tournament or take a shift driving the ice resurfacer. By building an ice rink, more than just the game of ice hockey prospers. In many communities, the ice rink has become the centre of social life where many other activities can be performed. An ice rink can also be used for figure skating, fairs, exhibitions, minor conventions and coaching clinics. By covering the ice sheet during off-season the arena can be utilized for other indoor sports such as basketball, indoor soccer, handball and inline hockey. There are several examples where an ice rink has served as a boost for a whole community. This manual wants to be the inspiration to start looking and finding ways and solutions in order to build a community rink. In this manual we will introduce a prototype that is not the cheapest possible solution to build a small ice rink. The prototype is a product of a marketing approach. It is a concept that offers modern comfort to visitors, both active and passive, through modern ice rink construction techniques. The rink should be an appealing place to all potential visitors. It should be safe, comfortable and give visitors the opportunity to enjoy their stay, whether it’s on the ice, in the small but comfortable restaurant, in the stands or in the dressing room. The rink should also be easy to maintain, with low overhead and investment costs. The writers of this manual feel that the prototype reflects all these wishes. The aesthetic design is the icing on the cake. We hope that you will be as fascinated as we are about the concept. 6 You can have an ice sheet in the desert in the United Arab Emirates or, as on this picture, in sunny California. 1.2 Introduction to ice hockey Ice hockey is a product of evolution stemming from existing sports, coupled with geographical and cultural parameters. Further, it is a team sport enjoyed by millions of players worldwide and viewed by millions more. It has been proclaimed the ”fastest team sport in the world“ Prototype of an IIHF rink INTERNATIONAL ICE HOCKEY FEDERATION and the object of the game, simply stated, is to score more goals than your opponent does. The fact that each team uses six players, including the goaltender showcases individual skill within a team concept, which ultimately provides a dynamic sport experience that is unique from game to game. While the exact origins of the game can be debated, it is generally accepted that ice hockey as is played today, took shape on Canada’s East Coast between the mid to late 1800’s. A form of bandy or ”Hurley on ice“ became logical for the settlers to this new land when confronted with the harsh winter conditions. Over time, local rules were implemented and equipment, particularly skates and the stick, were manufactured specifically for ice hockey. As popularity for the game increased over time, the sport began to be exported to other countries, especially as travel itself became easier. Many refinements regarding rules and equipment were instituted around the turn of the century but modifications still continue today as ongoing efforts to improve the game both on and off the ice persist. The first recorded indoor ice hockey game took place at Victoria Skating Rink in Montreal way back in 1875. From those modest beginnings, the game has transformed into a major modern indoor sport. The impact of enclosed arenas to the game is hard to overestimate. Technology has recently afforded the sport of ice hockey substantial opportunities to expand globally. No longer a function of climate, current facility construction allows ice hockey and skating in general to now be accommodated virtually anywhere in the world. It might be significant to note that it has been historically documented that a contained covered rink contributed to a common community spirit. This social type of gathering still plays an important part of today’s society, enabling people with similar interests to get together and cheer on their local ice hockey teams for the purposes of entertainment and civic pride. From an industry perspective, an indoor arena provides a greater potential to generate revenue because games can be played year round, regardless of the weather. Further, top class events can be planned with certainty, providing a guarantee of sorts to sponsors, spectators and even media, including television. With this in mind, it is not surprising that the appeal of the game goes far beyond just the participants. Ice hockey is an extremely popular spectator sport, whether it is viewed in person or via a television broadcast. Either way both men and women of all ages enjoy the fast paced action that is witnessed during a typical ice hockey match. Aside from the general traits required to excel at this sport, such as endurance, strength, balance and good hand-eye coordination, players show- 7 The Victoria Skating Rink in Montreal, Canada. The site of the first ever hockey game, March 3, 1875. INTERNATIONAL ICE HOCKEY FEDERATION 8 case a variety of skills specific to the game itself. This includes not only the ability to skate within the context of the contact sport that hockey is, but also to be able to stickhandle and shoot the puck while in motion. Because of the mass appeal, the game lends itself to be marketable from a number of perspectives. Corporations frequently benefit from their association with this dynamic sport and can brand its product or service via the game. The demographics of ice hockey, despite variations from country to country, reveal that most arena patrons are aware of advertising within the building, and typically have a higher than average income. When mixed with an exciting product on the ice, all parties stand to benefit. Today, corporations go beyond the traditional static advertising as has been evident within the rink and on the equipment of the players themselves. In a sense they exhibit a form of vertical integration, actually taking ownership of the building and/or sport franchise in efforts to generate a greater awareness of the company and ultimately additional revenues. Similarly, in North America, a trend has started with professional ice hockey teams building skating facilities locally as a way to develop and nurture a grassroots core of players who become spectators and purchasers of team merchandise. By entering the rink ownership and operation business, the team and any associated partners strive for long-term growth in their local market. Therefore, where traditionally a skating facility was viewed primarily as part of the community’s infrastructure, not unlike a park or a library, today’s arena projects are examined in economic terms with revenue and expense implications. Naming rights, private boxes, concession, along with innovative advertising opportunities are just a few examples. Chapter 1 Modern professional ice hockey is played in 10 000 plus arenas. The action is fast-paced and the competition fierce. Here, Canada plays Russia in the IIHF World Championship. The public interest in ice hockey. one development will lead to recreational sports as a lifelong athletic pastime. shows. Ice rinks are attractive sports and recreational facilities promoting health and social activity as a key element of “quality of life”. all-weather facilities available during 6-9 months of the year are usually in short supply.

An advantage of the Learn to Skate and Play programs is that during each session. one weekday afternoon session and a Saturday morning or afternoon session should be offered as a minimum. or ”quiet hours“ in a facility. Learn to Skate & Learn to Play Hockey programs The Learn to Skate and Learn to Play Hockey programs are the foundation of a successful facility. Public skating also allows the rink management to introduce customers to other. A public skating session is usually an inexpensive means to introducing customers to your facility. These types of program are very important to keep skaters coming back to the rink. either figure skating or hockey. skate at the rink. they will choose the sport that they will concentrate on.

Sessions are typically either one hour or 90 minutes in length. as many as 8 different classes. Similar programs may be offered during the “quiet hours” that target the adult or senior community. Ice time is reserved and players register individually for each session. Scheduled times can vary depending upon the community. public skating sessions are important in operating a successful ice facility. and could be operated from 4 to 6 PM. Depending on the community.

These classes can be offered during weekday mornings when the older children are in school. Young hockey players arrive for practise. This scheduling will allow the facility to schedule 3 to 4 class sessions during a 2 hour time period. If children can demonstrate a minimum proficiency on the ice.INTERNATIONAL ICE HOCKEY FEDERATION 10 The rink is virtually never closed. and community participation. Saturday sessions provide the opportunity for all family members to participate. Public skating In many areas. it is difficult to accommodate the needs of all the user groups.

Parents are able to skate with their children. This program should be received with open arms by the rink industry. Most public skating sessions average two hours in length. weekend evening sessions on Friday or Saturday nights have become traditional. These are the suggested minimum public skating times. ✔ Weekday mornings. from 3 PM to 5 PM with music that caters to the 10 to 14-year-old crowd. from 6 AM to 9 AM. There are other public sessions that work quite well in some regions. A new figure skating activity. Make these sessions available for school groups.

The basic technical elements of a well-working facility are: • Insulated walls and ceiling • Efficient refrigeration plant • Mechanical ventilation • Efficient heating system • Air dehumidification 1) Insulated walls and ceiling makes it possible to control the indoor climate regardless of the outdoor climate. decay in wooden structures and indoor air quality problems like fungi and mould growth etc. The heat from the rink is ”sucked“ by the compressor via the rink pipes and the evaporator and then released to the surrounding via the condenser.

The ceiling is cold because of the radiant heat transfer between the ice and the ceiling i. etc. Depending of the surroundings there might also be noise problems with the open-air rink – traffic noise may trouble the training or the slamming of the pucks against the boards may cause noise nuisance to the neighbourhood. Refrigeration plant includes the compressor(s). Ventilation is needed both in the public spaces (dressing rooms. the ice cools down the inner surface of the ceiling.1 General introduction Ice rink facilities share all the same concerns: energy usage. Refrigeration plant is the main energy consumer in the ice rink facility. Air infiltration will increase energy consumption during the warm and humid seasons related to refrigeration and dehumidification and during the cold seasons this is associated with space heating. This leads us to the fourth basic demand: the ice rink facility must be heated. 2) The refrigeration plant is needed to make and maintain ice on the rink. 3) Mechanical ventilation is necessary to be able to control the indoor air quality and thermal as well as humidity conditions inside the ice rink. This will require investment in energysaving technology and in raising energy awareness on the part of ice rink operators. Though there are technical solutions to minimize the indoor rain problem (low emissive coatings) the ceiling only solution is still subjected to weather conditions and high running costs. If you ever have visited a dressing room when the ventilation is off you will realize the necessity of the proper ventilation. rain. Compressors. pumps and fans needed in the refrigeration system are normally run by electricity and their electricity use may cover over 50 % of the total electricity use of an ice rink facility. 15 Chapter 3 . Inadequate ventilation will cause also health problems in the hall. To be energyefficient air renewal must be well controlled. In an open-air rink the operation is conditional on the weather (sun. This means that the ice rink enclosure should be airtight so that there are no uncontrollable air infiltration through openings (doors etc. Energy costs and concern about the environment sets high demands for the technical solutions. Ice rink design and operation are totally unique and differ in many ways from standard buildings. High humidity of indoor air will bring on corroding problems with steel structures. Obviously there are special needs to have technical building services to control the indoor climate and energy use of an ice-rink facility. replacement) costs will increase and short service life time of such a system is expected from the environmental point of view.e. Advanced technology can reduce energy consumption by even 50 % and thus decrease operating costs in existing and proposed ice rink facilities while improving the indoor climate. cafeteria. Potentially a lot of savings can be made if the facilities are got operating as energy-efficiently as possible. Thermal conditions vary from -5 ºC on the ice surface to +10 ºC in the stand and +20 ºC in the public areas like dressing rooms and offices. and rink pipes.) and in the hall. Ceiling only construction helps to handle with sun and rain problems but may bring about maintenance problems in the form of ”indoor rain“: humid air will condensate on the cold inner surface of the ceiling and the dripping starts. Excess moisture in indoor air will cause corrosion of metal structures. The key to the effective utilization of the energy resources in new as well as in retrofit and refurbishment projects is in the consciousness of the energy-sinks and the various parameters affecting the energy consumption. plant system and operation define the energy consumption of an ice rink. ice temperature. plant system and operation define energy consumption of an ice rink. rotting of wooden structures.

The most common surfacing materials is: • Concrete However sand surface is cheapest and fairly energy economical because of the good heat transfer characteristics but the usability is limited to ice sports. walls The outside wall structure of an ice rink is commonly also based on the idea of air tightness and the simplest walling is done by using different metal sheet panels. Typical ice pad construction. in a concrete slab the mounting depth is normally 20–30 mm and the mounting space between the pipes is 75–125 mm. The cooling pipes are mounted quite near the surface. The ice pad consists of ground layers below the pad. Therefore it is recommended to use in a lower partition of outside wall sandwich elements of concrete and replace them over 2.

Chapter 3 . Chapter 3 When estimating the energy economy of the system it is essential to focus on the entire system and not only on one component alone. Needed cooling capacity depends on the temperature of the structures at the beginning of the freezing and the required freezing time (normally 48 hours). The refrigeration capacity is normally sized according to the heat loads during the ice making process. • Cooling the temperature of the flooded water to the freezing temperature (0 ºC) and then freezing the water to form the ice and to cool the temperature of the ice to the operating temperature.Lower energy efficiency than with direct system 26 In most cases the refrigeration plant comprises the refrigerant circuit refrigerates an indirect system i.

For a standard single ice rink approximately 300–350 kW of refrigeration capacity is adequate. the operating temperature of the ice and the required freezing time (48 hours). • Convective heat load between the rink surface and the air. Refrigeration unit and related energy flows. In choosing the refrigerant the country-specific regulations must be taken into account. for example natural substances like ammonia (NH3) and carbon dioxide (CO2) or HFC refrigerants such as R134a. which enables demand-controlled running of the system. The dimensioning cooling load during the freezing period is comprised of the following components: • Cooling the ice pad construction down to the operating temperature in required time. In the compressor the vapour is raised to high pressure and high enough temperature to be above that of the cooling medium so that heat can be rejected in the condenser.

If the ground is frost-susceptible and the frost may cause uneven frost heave of the ice pad. one for the rink area and one for the public areas. The underlying energy-thinking in the heat resistance is. Heat resistance consists of five different parameters: (1) the so-called surface resistance of the ice surface. which has effect on the energy consumption. In the construction of the ice pad the ground frost insulation and in some cases ground heating is necessary (condenser waste-heat can be used for heating). mainly dependent on the ice thickness. high efficiency.1.

The simplest and safe way is to equip the facility with two ventilation units. The air-handling unit(s) provides fresh air to the ice rink and other premises and it is also used for heating purposes and even to dehumidify the ice rink air. The energy-saving factor in ventilation can be found in the demand-controlled fresh-air intake and in optimising the airflow rates according to the needs for minimizing the fan power. the bigger the resistance is the lower the brine and evaporation temperature of the compressor should be in order to produce the same cooling effect as with smaller resistance.

Air is passed over a cooling coil causing a portion of the moisture in the air to condense on the coils' surface and drop out of the airflow. There are two primary ways to remove moisture from the air: cool the air below its dew point to condense the water vapour. High humidity levels cause also indoor air problems by enabling the growth of mould and fungus on the surfaces of the building structures.

Increasing ice thickness brings about higher electricity consumption of the refrigeration unit and makes the maintenance of the ice more difficult. humidity condensing from the air onto the ice. Surface water drains for melted water from ice defrosting is required outside and around the rink. Ceiling radiation is generally the largest single component of the heat loads.INTERNATIONAL ICE HOCKEY FEDERATION 32 Chapter 3 the hot water must be heated at least up to +55 ºC.9. Other ice heat-load components are: the convective heat load of the ice rink air temperature. Instead. which is relative to the luminous efficacy of the lamps. The humidity of the ice rink air tends to condense on the cold ice surface. imposed by the resurfacing of ice with flood water in the range of 30 °C to 60 °C and 0. The convective heat load is relative to the temperature difference between the air temperature and ice-surface temperature and the air velocity above the ice. The thickness of the ice must be controlled weekly in order to maintain the optimal thickness. The most effective way to reduce convective heat load is to keep the ice temperature as high as possible and the air temperature as low as possible. which increases the ceiling radiation as well as the convective heat load of the ice. In new facilities. pipe material and hydraulic sizing of the pipe network and the evaporator.05) of the aluminium foil facing the ice that makes this system so effective.

Warm soil under the floor is a minor heat load on the refrigeration. and pump-work of the cooling pipe network. Pump-work is affected by the cooling liquid used (there are several alternatives). Humidity problems are one indication of the possible moisture damage in the structures and thus must be taken seriously. The thickness of the ice tends to increase in use. ice maintenance. The higher the air temperature is. Rising of 1°C of the ice temperature gives 40-60 MWh savings in electricity and 70-90 MWh savings in heating per year in year-round operation. namely the rink melted water drainage and the melting pit of waste-ice. This load. besides the ice rink air temperature.6 Energy consumption optimisation Energy consumption of the refrigeration unit is subjected to the heat loads of the ice. It is the low emissive property (emissive as low as 0.8 m3 of water per one operation. ground heat. lighting. The amount of heat radiated to the ice is controlled by the temperatures of the ceiling and ice surface and by proportionality factor called emissive. Lighting forms a radioactive heat load on the ice. 3. A lower floodwater volume and temperature should be used so reducing the refrigeration electrical use and the cost of heating the water. This phenomenon is mainly dependent on the outdoor air conditions and can be overcome by dehumidification of the ice rink air. Most building materials have an emissive rate near 0. the low-emissive surface reduces heating demand and improves the lighting conditions of the rink. Moreover. humidity problems may occur from a dripping ceiling or as fog above the ice. Recommended ice thickness is about 3 centimetres.4 to 0. which affects the electricity consumption of the compressor and the heating energy consumption is the ice temperature and ice thickness. Waste-heat from the refrigeration plant can be utilized to lower the energy consumption of hot water for example to heat the resurfacing water and to pre-heat the hot water. The most common low-emissive material used in ice rinks is aluminium foil. which can be dealt with sufficient insulation between the soil and the cooling pipes. The system pump-work is a heat load on the refrigeration system due to the friction in the cooling pipes and in the evaporator. The temperature level of the ice rink air has a significant effect on both the electricity consumption of the refrigeration unit and on the heating energy need. the warmer the ceiling is. Ice resurfacing is one of the highest heat loads of the ice after the ceiling radiation and convection. Materials that are perfect radiators of heat would have an emissive of 1. In the sewer system of an ice rink there are two special systems to be taken care of. . Studied ice rink locations: Helsinki (Finland).

In some cases treated water is used for cooling the condensers of the ice refrigeration plant.INTERNATIONAL ICE HOCKEY FEDERATION 36 4. Water consumption rate is the same for all the studied three cases. It is impossible to give exact or general figures of the loads for example because of the variety of energy production profiles in each case.

The idea of this manual is to offer technical and financial guidelines for a ”small“. Ice rinks are special type of buildings and should be treated as such. To have the temperature just above the ice surface on . due to ignoring the humidification issue in the mechanical plant. The operation of these coming facilities is based on earlier experience of the investors. These features are not comparable to common buildings. Public skating and equipment rental are good ways to boost your income. with the right technical features and skilled maintenance personnel will have a considerable effect on the level of operating costs. Advanced technology can reduce energy consumption and operating costs by up to 50 per cent in existing and proposed arena facilities. which is not the most low-priced and simple facility. A modern ice rink needs special tools to control the indoor climate.4 and 3. especially the temperature and humidity factors. The result of this decision is that the technical features are chosen. 38 Chapter 4 4. The IIHF working group has made the decision to design an IIHF ice rink prototype. Like in major multi-purpose arenas. while providing the customer with high-level service and wide range of activities. This element plays a key role in the decision to invest in a new ice rink. Unfortunately. where some hundred ice rinks have been built in last thirty years. the special features of an ice rink must be known. A clever design in combination. In order to have a proper cost and operation structure for a new ice rink project. This means within 2 to 3 years. . it will be rather easy to change the ice surface quickly into a dry-floor facility. Energy costs make it necessary to strive for energy efficiency. there are still plenty of new ice rinks and arenas being developed without the input of specialists. Even in a country like Finland. Technical solutions that are too simple can cause extremely high operational costs. The continuous increasing demand of the public is resulting in a higher requirement for the quality of the ice rink indoor climate. but +18 degrees centigrade only a few meters behind the dasher board on the first seating row are common requirements in many ice rinks and arenas.1 Introduction There are a lot of construction projects for new buildings of any use running all around the world continuously. Too high humidity of the indoor climate can easily cause serious corroding problems in steel structures and decay in wooden structures.3. The technical features are described more detailed in chapters 3. the decisionmaking is rather simple. The IIHF prototype ice rink provides a palette of services for on ice and dry floor possibilities as mentioned in Chapter 2. In these projects. modern ice rink. even if the decision makers are not professionals in the construction business.2 Construction costs The different structural solutions. layout and volume of the facility. This prototype is a customer-based facility that gives operators and investors the opportunity to operate an economically successful facility. Saving costs in the wrong area will lead to serious damage in a short period of time. The later success with respect to the operational costs is made in the design phase. If one does not take these elements into into consideration they might cause remarkable problems in a very short time.4 degrees centigrade. while also improving the indoor climate for the customers. some wood framed ice rinks have major decay damage only 4 years after the completion.INTERNATIONAL ICE HOCKEY FEDERATION Economic profile of the IIHF ice rink prototype Chapter 4 4.

Due to the fact that a single sheet facility may operate for 18 hours a day. In many cases the lower labour cost level is balanced by paying extra on import taxes of technical equipment or by the increasing number of employees because of the lack of machines. it is possible to utilize volunteer staff to cover many of the hours. It is also important to work with the local utility companies to establish favourable agreements for the facility. However one should be aware that volunteer work ethics and expertise might be lacking. The cost estimate shown in the manual is based on the location in the city of Munich. should be looked at on a case-by-case basis. and water. the total number of staff can be adjusted.INTERNATIONAL ICE HOCKEY FEDERATION 40 This is a turn-key cost estimate for IIHF prototype ice rink. It is important to have a staff that understands the ice business and can operate the facility at maximum efficiency and profitability. The Chapter 4 4. the cost to open an ice facility is substantial. . welltrained staff to help the rink succeed. As previously noted. mortgage payments. Germany. The owners cannot simply turn off the electricity to the refrigeration plant when the building is closed.1 Expenses The major utilities required in an ice rink operation are electricity. List of monthly expenses ✔ Financing costs ✔ Utilities – electricity ✔ Utilities – gas ✔ Utilities – water. This calculation merely gives you as an investor. When making the budget for the operational costs one should take into consideration the tasks that could be fulfilled by volunteers.3. There are proven methods to efficiently operate an ice rink. The IIHF working group would like to underline that this cost calculation is not a cost guarantee in any form. a bigger staff will be necessary. Maintaining a sheet of ice is a 24-hour commitment. Also monthly fees related to the external financing (see chapter 5). The tasks could be: • Maintenance of the facility • Cleaning • Ice resurfacer maintenance Also mechanical service contracts have to be included. even when we use the same technical definitions. a good indication of the total cost when you have decided to build a small ice rink.

For a successful operation. 7 days a week. On the other hand it is rather easy to transform this cost estimate into another calculation form. the facility will need related man-hours to cover the operation. The model of the cost calculation is based on the German DIN 276 – form.3 Operational budget 4. The costs of the site and the utilities are not included in the total summary. which could include maintenance of the refrigeration plant and the ice resurfacer. These are also the items of the costs in order to have neutrality in the cost estimate. With larger public sessions or special events. A common way to reduce the fixed costs is to negotiate partner agreements with a local telephone company or a local garbage disposal company or other similar companies. maintain the building and keep it clean. maintain the facility. The assistant rink managers typically take care of the evenings and weekends at the facility. This person would serve. that an ice rink with two ice pads can be operated with the same amount of staff as the single ice surface rinks. A facility should also have one full time. With a plan for staff training and education. can be reduced in comparison with the doubled user capacity of the facility. a marketing director may be hired to promote the facility and the many diverse programs that are offered to the community. They are also responsible for ice maintenance and resurfacing the ice. depending on the type of rink operation and the region. A hockey director would operate in a similar manner to manage the hockey operations at the facility.000 €. In addition to this staff. work evening or weekend shifts. a single sheet facility may have 2 to 3 additional part time operations staff that can drive the ice resurfacer. As the ice rink industry evolves and changes. it is important to keep staff up to date on the latest advancements in the industry. an average annual level of expenses in 2001 in Europe is between 300. The duties of the manager in a single sheet operation include. rink operators will have the opportunity to learn more efficient and cost effective methods to running an ice rink.

Another key to success is to offer programming that will allow your customers to stay with your facility for a lifetime. this has yielded a lower burden on the current budget for facility operation. and the operating costs are less heavily burdened year after year. This kind of financial participation takes a weight off the investment budget. The analyses of demand for such a facility.3 described the main construction and annual costs of the IIHF Prototype Ice Rink with a standard 30 x 60 m ice pad and a program of operational and other ancillary rooms. For the public partner it is important to reach user-friendly agreements early on with the private partner concerning opening hours and socially acceptable pricing. the private side is put in a more profitable position than was possible in the past through the free provision of building land by the local authority (or by the payment of a token fee). The possible but locally divergent initial position there is clearly indicated by the span of the different figures in the expenditure and income positions. If the construction and engineering services are correctly designed and specified. In the meantime. say. and of the required space and rooms are the same as before. The design and tendering procedure require the same care (see above) and the companies for construction and interior finish must be selected according to the same criteria as in the past. In its entirety. this investment money came solely or mainly from tax revenue. Due to low interest and loan repayment instalments. In many places.INTERNATIONAL ICE HOCKEY FEDERATION Financing Chapter 5 5. the construction of ice sports facilities in countries with an ice sports tradition used to be financed by local authority institutions. The expenditure side depends on the structural and technical quality of the facility. the interest and repayment instalments are lower.2 Operational costs Chapter 4. 43 5. many of which fall within the concept of public-private partnership (PPP).1 Construction costs / Investment costs As mentioned in the introduction. These institutions were frequently supported with construction grants from the regional governments or central government. The income side is affected by such factors as the location.g. the private partner will not enter into agreements that put at risk the achievement of a surplus in facility operation. the private sector has emerged as a provider of ice sports. the economic situation of the public sector in most countries has changed dramatically. The preparation of a public-private construction project does not differ qualitatively from earlier forms of project financing and realisation at all. and the various energy. The shifting from governmental financing and operation to commercial organisations changed the management philosophy of sports facilities greatly as will be discussed in 5. by providing either funding or manpower for construction and equipping activities. which is not too lavish but fully meets the needs of a modern facility. water and disposal charges. Of course. Later the role of the government was debated and tasks that were usually appointed to these governments were now put in the hands of private organisations. New ice sports facilities these days make use of entirely different forms of financing. sports clubs can also act as private partners. There are nevertheless limits to the latter. and in some cases also from the surpluses of national or regional sports or other lotteries. The process of privatisation had started. because work performed by the sports club on a building with sophisticated engineering like an ice sports facility is generally only feasible for a small number of construction and technical tasks. Investors have been found as a source of finance whom. e.2. 20 years with an option of renewing the agreement or buying back the property. . In this context. rather than having their profits skimmed off by the tax authorities. If the design and construction of the building is controlled by a commercial operator. Given favourable terms and reliable partners. have enjoyed high tax write-offs (loss allocation). A special form of PPP is the leasing of a property for a period of. It started in the 1970’s due to the industrial decline and the heavy burden of unemployment on society. the level of staff costs. On PPP projects. certain legal obstacles can be evaded. This reduces overall project expenditure. the guidelines (regulations) for State-awarded contracts.2 and 4. a leasing agreement also ensures that the ice sports facility remains in immaculate structural and technical condition throughout the term of the leasing. This is where the public sector and commercial industry search jointly for sources of finance. construction costs can be reduced without any diminution of quality. depending on the tradition of ice sports in that particular region. The successful operation of the facility in the long term can only be ensured if the revenue surplus covers the interest and repayment instalments as well as sufficient upkeep of the building and its installations. instead. This represents an appreciable cut in annually recurring costs. indoor ice rinks with artificial ice should be sited in communities with between 20. initially low reserves should be set aside from the outset. If. A continuous theme is that of the quality of the work performed by the various trades. admission pricing. it is important to highlight the effect that appropriate (not excessive) quality can have on a building’s life cycle. . The population density per square kilometre should be at least 150 within a 12-kilometer radius. Only high capacity utilisation rates can warrant the investment and recurring annual overhead and maintenance costs associated with an adequately staffed. The construction of an ice rink should be considered wherever the following basic prerequisites are met: In moderate climate zones. Usually it can be assumed that 20 % of costs arise by construction and 80 % by operation and maintenance – from the start of construction through disposal. such as Central Europe. state-ofthe-art facility of this type.000 inhabitants.
