1 Commercial Developments Tivok Energy Thermal Systems

2 RESIDENTIAL/COMMERCIAL DEVELOPMENTS Apartment buildings service many different units separately and hot water usage has to be billed. Large scale commercial heat pumps are ideal for this situation due to efficient use of space and highest performance output of any hot water system available. Figure 1: Example Commercial Split System Layout Another advantage of using Tivok heat pump systems is the ability to service many different hot water requirements using one centralized system. This includes swimming pools and domestic hot water requirements. Along with high efficiency hot water heating, heat pumps also expel cool air as a by-product. This cool air can be ducted to contribute to common area cooling as a free cooling source. This further improves financial performance of a heat pump system

3 DIRECT BENEFITS OF TIVOK TECHNOLOGY Tivok Energy Solar Thermal Systems are able to provide many benefits to both new and old developments. Here are some of the most attractive benefits of using Tivok Energy Thermal Technology for property developers. PROPERTY BENEFITS Tivok products can reduce the strata fees and increase the property value of both new and old developments. According to Strata Community Australia, energy efficiency is the easiest way to reduce the costs of strata and shared strata services are usually the largest consumer of energy in large buildings. REDUCE THE COST OF STRATA FEES WITH TIVOK ENERGY THERMAL TECHNOLOGY DIRECT ENERGY SAVINGS Compared to existing gas and electric technology Tivok Energy Solar Thermal Systems can provide both energy and monetary savings in excess of: 65% FOR GAS 85% FOR ELECTRIC GREEN STAR AND NABERS By utilising energy efficient technology, additional value can be generated for both old and new developments. With the increasing relevancy of energy efficiency to both governments and consumers, maintaining a high Green Star or NABERS rating is an easy way to add proven value to developments. BE RATED AS A WORLD-LEADING FACILITY BY USING TIVOK ENERGY THERMAL TECHNOLOGY RESALE VALUE According to the Department of Environment, there is a statistically significant relationship between property value and energy efficiency. The study found that energy-efficient properties in the ACT gained around 3% additonal value for each additional star in the ACT Government s EER scheme. ADD PERMANENT TANGIBLE VALUE TO DEVELOPMENTS USING TIVOK ENERGY THERMAL TECHNOLOGY 2014.

4 TECHNICAL ADVANTAGES Heat pumps work by absorbing heat from the surrounding air and transferring it into water (Air source heat pump technology). Along with heating water, it also expels cold air as a by-product which can be used for space cooling. The climatic conditions that are humid and hot are ideal for the operation of heat pumps, resulting in very high Coefficient of Performance, ensuring year-long high performance. Typical performance and yields for our heat pump systems are as below: Figure 2: COP Levels for Tivok Heat Pumps based on atmospheric data By combining heat pump technology with solar thermal collectors, the savings are increased even more by using the sun s thermal energy during the day to contribute to hot water requirements. None of this heat is wasted because it is stored in our vented energy banks which contains a 65mm insulation layer, 15mm above industry standard, minimising heat loss. WHAT ARE HEAT PUMPS? Tivok Energy Heat Pumps extract the heat energy from the air and use a high-efficiency heat transfer process in order to maintain constant non-interrupted hot water. The cool air created by the heat transfer process can be used for space cooling purposes. Heat Pumps generally assist Solar Collectors however they are also a capable system on their own

5 TECHNOLOGY COMPARISON Heat pump technology is currently the highest efficiency hot water heating system available. It operates at above 350% efficiency; this is 3 times compared to electric systems and 4 times compared to gas hot water heating systems. 400% 350% 300% 250% 200% 150% 100% 50% 0% Electric Gas Heat Pump Figure 3: Comparitive Efficiency Graph What this means financially is that there is a very attractive payback scenario when compared to using an older technology. Tivok Heat pump systems are designed to be modular and can be sized for a range of hot water capacities and applications without affecting performance and operating efficiency. WHAT ARE SOLAR COLLECTORS AND HEAT PUMPS? Solar Collectors use the heat energy from the sun to directly heat water for use in hot water systems. This is in contrast to Solar PV which uses the heat energy from the sun to generate electricity. Solar Collectors can provide a substantial contribution but due to weather factors a secondary heat source is also required. Tivok Energy Heat Pumps extract the heat energy from the air and use a high-efficiency heat transfer process in order to maintain constant non-interrupted hot water. The cool air created by the heat transfer process can be used for space cooling purposes. Heat Pumps generally assist Solar Collectors however they are also a capable system on their own

FINANCIAL PERFORMANCE PRICES Correct system pricing allows for payback below 4 years in metropolitan areas where utility prices are usually lower. Most commercial project managers consider a 4 year payback as quite good. When one considers that traditional fossil based water heating sources can t provide any payback period over energy savings at all, Tivok systems stand out. UTILITY RATES Tivok systems target the current utility rate situation that allows energy efficiency and renewable energy to directly be competitive compared to older technologies. In Australia, we find that since 2012 onwards, with the acceleration of utility cost growth, our technologies have become increasingly attractive. Tivok systems provide a shorter payback period when they replace older electrical heating technology as our technology uses only 20% of the energy of electrical resistance heaters

7 PAYBACK GRAPHS TYPICAL AUSTRALIAN COMMERCIAL RATES Figure 5: Payback Scenario compared to Electricity at various price points for fully installed retrofit systems TYPICAL AUSTRALIAN COMMERCIAL RATES Figure 6: Payback Scenario compared to Natural Gas at various price points for fully installed retrofit systems Worldwide gas prices are continuously rising and this is a good indication that Tivok s water heating technologies will provide targeted or better paybacks. As utility rates keep rising, Tivok s thermal systems become more and more vattractive

8 CASH FLOW AND PAYBACK In our case we find that our technologies consistently offer payback of less than 4 years for commercial installations. This is currently the lowest offer of any hot water heating technology available. Once the payback period is achieved, the cash flow the facility had used for utility cost is either available as added profit, or can be used for other investments. (Gas price of $22/GJ and electricity price of 0.20/kw with a price escalation of 6% pa FINANCING Figure 7: Comparative Cashflow Graph Projects financed over a course of around 5 years will potentially result in a zero to monthly cash flow balance. This results due to the amount of operating cost savings equating to the monthly expenditure on repayments. The business is able to purchase the system without having any upfront costs. Their usual operating costs stay the same, but now this operating cost has a dramatically reduced fuel component and has a repayment component factored in. In this way, the business is shifting costs away from unrecoverable fuel costs and into building an asset (in the form of equipment) that will continue to make savings into the future. Repayment expenser is also tax deductable. The added value of the infrastructure is recoverable when the asset is sold, or can be used for increased borrowing after the system has been fully paid

9 FINANCING OPTIONS With such high returns and short payback periods, the burden of upfront cost is much lower and financing options up to 5 years may not need to be applied. Tivok Energy has multiple sources that lease or finance these systems for commercial users at competitive rates. Tivok Energy receives no compensation from these sources for inclusion of their rate information or if the client uses them to lease or finance their systems.

10 INDUSTRY-LEADING TECHNOLOGY ENERGY BANKS Our proprietary technology allows a singular hot water system for many different requirements while preserving water purity. Using our energy banks, hot water produced during the day by solar thermal collectors can be stored under very high insulation, allowing minimal heat loss to surroundings and maximizing the renewable (free heating) component of the hot water heating system. The technology is non-pressurised by design to allow long system life and eliminate the potential for system failure due to line pressure. Tivok has never had a problem with leaking tanks. Maintenance is minimal, just superficial cleaning of the outside of the tank if dust and dirt accumulate. HEAT PUMPS Tivok offers a range of sizes for both domestic hot water heat pumps and swimming pool heat pumps. Each heat pump is designed to perform with a coefficient of performance above 3.5 (as seen in the diagram below) and is designed for long life and consistent output. Energy Banks Heat Pumps Heat pumps also expel cool air during operation and can be modified to chill water simultaneously with its heating operation. This functionality offers multiple savings from one heat pump unit. Evacuated U-Tube Solar Collectors Figure 2: COP Levels for Tivok Heat Pumps based on atmospheric data EVACUATED U-TUBE SOLAR COLLECTORS Our solar thermal collectors employ the most advanced passive solar thermal technology and warranted for 15 years. Evacuated direct flow U-tube technology is the safest, longest life and highest efficiency solar thermal system available today and unlike competitors, maintains its efficiency throughout its entire lifetime. Unaffected by dusty condition, and self-cleaning, these collectors provide the equivalent of 1.04 kw of water heating power at standard sun conditions

11 TIVOK TECHNOLOGY Tivok Energy has completed or is in the process of completing installations at multiple facilities that provide housing and associated services. These are the same services that mining infrastructure facilities provide. A few relevant current or past installations include a Luxury Resort in Arizona, USA; a mixed-use residential and commercial Government Building in Camperdown, NSW; a large shopping centre in Mt. Druitt, NSW and a short term accommodations facility in Drummoyne, NSW. These systems provide hot water for bathing, commercial kitchens, and laundry use. The installations at the Government facility and the Shopping Centre have Solar PV components that provide electricity as well. The Shopping Centre installation also redirects cooling from the syt supplemental cooling for interior use. The wide geographical location of these services is also a testament of the ability of Tivok to successfully complete remote projects at a distance from our headquarters. These installations show case the flexibility and adaptability of the Tivok Technology. They also demonstrate the deep intellectual property in the Tivok Organisation to design and install systems that are productive for a variety of applications in a wide range of areas.
