3 Scale up your expectations VRV Systems have developed considerably over the past number of years and are now being specified for larger and more diverse buildings. The latest VRV solutions can be designed on a greater scale than ever before to create fully integrated systems for all kinds of buildings, even those over 5,000m 2. The ability to use custom design tools, combined with modular flexibility, total heating and cooling system integration and intelligent controls, means that the system can be adapted to changing tenants and occupant levels. This makes VRV solutions incredibly versatile, enabling them to meet both current and future building requirements.

4 Decisions, decisions, decisions... There are many decisions to make before determining the optimum climate control solution. Building regulations, energy efficiency targets and planning guidelines all represent significant challenges to be overcome before you can choose an efficient solution that minimises plant space and running costs, while meeting your current and future needs. Minimising plant space It has never been so important to maximise lettable floor space. Every square foot counts, so minimising plant space for climate control systems is good economy. Franklin + Andrews, one of the world s leading construction economists, estimates that a two or four pipe fan coil system could take up around 7% of the overall floor area of a building, while a comparable VRV solution would take up about 3 to 5%. So a VRV system takes up 29% less plant space than a chiller system, and in a highly competitive market place, offering the most flexible and efficient use of office space could be a real deal breaker. The modular nature of VRV means the outdoor units can be placed in different locations, either together or spread around the site, avoiding the problem of finding one large area for plant. Suitable for any building size VRV is often perceived as one step up from a split or multi split system and therefore only suitable for small to medium sized buildings. In fact, VRV s modularity makes it incredibly versatile. Multiple units can be combined to create a whole building solution Systems can be designed, built and commissioned floor by floor - ideal for installing a new system or remodelling in phases Piping lengths can be up to 1,000m overall Reducing whole life costs The height difference between indoor and outdoor units can be up to 90m In a tough economy, it s important to look at the whole life cost of a climate control system, not just the initial investment. Franklin + Andrews Little Black Book states running costs of two and four pipe fan coil systems as 8.75/m2 and 10.75/m 2 of gross floor area respectively. By comparison, running costs for VRV heat recovery systems are only 6.25/m 2 of gross floor area 29% to 49% lower. So opting for a heat recovery solution could save many thousands of pounds per year. A well-maintained VRV system can last for many years. VRV III units, introduced in 2006, have now been on the market for eight years and have a minimum nine years of spares provision, giving a potential life of more than 17 years. The new VRV IV modules now being introduced are designed to be compatible with VRV III, which will lead to a potential system life of 24 years. VRV s modular nature means different components can be replaced throughout its life. This allows the latest technology to be incorporated, which can result in lower maintenance costs and higher efficiencies. Outdoor units can be placed together or spread around the site, which can also minimise floor loading and noise. User comfort VRV manages user comfort effectively in a number of ways. For example, fan coils have independently controllable louvres, plus presence and temperature sensors, to direct air flow away from occupants and towards areas where temperature is out of balance. Individual control of units means systems can react quickly to changing loads and comfort requirements. Cold air dumping during defrost is being tackled through innovations such as the phase change material module in the VRV IV unit, which enables off coil temperatures to be maintained during defrost cycles. 3 VRV For Large Scale Buildings

5 Property developers Developing intelligent climates The latest VRV systems can enhance a building s value by using the latest technological developments to lower costs, enhance functionality and increase efficiency. This helps to ensure there is a quick turnaround time between tenancies as well as helping to achieve the highest rent per square foot. Intelligent climate control solutions Many buildings operate separate systems for heating, cooling, refrigeration and hot water, wasting a huge amount of energy. However, intelligent planning can use waste heat generated by air conditioning and refrigeration in other areas of a building. Advanced VRV solutions offer a totally integrated approach to climate control, which deliver a complete solution that maximises energy efficiency by simultaneously heating spaces while cooling others. Maximising rental space VRV solutions are modular in design, giving greater flexibility to create a system that s tailored to your exact building requirements - while taking up around 29% less plant space than a typical chilled water system. The heat pump can be installed: Outside on a roof, wall or at ground level Appealing to cost conscious customers These energy efficient systems are not just more sustainable, they are much cheaper to run too. In a plant room - to minimise impact or external noise In shafts and ceiling voids - as small refrigerant piping takes up less space, thus maximising the commercial lettable area. VRV solutions can dramatically reduce the cost of hot water and heating by recovering heat and reusing it in a precisely controlled way to create the perfect climate conditions. Developers will find buildings with intelligent climate control solutions are much more in demand from customers, who want an efficient environment that promises low running costs, without compromising on comfort. Flexible indoor space VRV systems can be designed, built and commissioned floor by floor. This makes it possible to install new cooling systems within a phased refurbishment programme, or to adapt them for individual needs within a multi tenanted building. Systems can be changed with sections decommissioned or added to as required and indoor units have the flexibility to direct air or restrict air flow if internal spaces are re configured.

6 Consultants Freedom to design Daikin VRV systems are based on air source heat pump technology, so they can help to meet renewables targets, while assisting consultants with Part L compliance and achieving higher BREEAM ratings offering a genuinely versatile solution, designed to meet a building s precise renewable requirements. Individually tailored solutions VRV provides greater flexibility to meet current and future client needs. Because the system can be designed and built to meet any building s requirements, it offers solutions to a wide range of spaces, from large open lobbies and reception areas, to individual rooms and offices. VRV can also be combined with water cooled systems connected to geothermal or hydrothermal sources, as well as giving the option of adding water heating, solar collectors or refrigeration into the system. VRV s control options also allow you to tailor the control regime to meet the requirements of each room, floor or tenant as required, to maximise energy efficiency and prevent energy waste. This versatility makes VRV ideal for buildings with multiple tenants, which may have vacant areas and variable periods of high and low use. Achieving a balanced mode of heat recovery within a VRV system can deliver dramatically higher energy efficiencies, achieving COPs of more than 10 and helping to maximise BREEAM credits at design stage. This involves specifying the system so that it is capable of cooling areas of the building with the highest heat gains and transferring reclaimed heat to other areas requiring heating or hot water. Recovered heat can even be diverted to over door air curtains, thus saving up to 67% in running costs, compared with electrically heated models. Flexible configuration options Every building is unique, requiring efficient usage patterns and varying occupancy levels. A fully integrated system can be designed that opimises energy efficiency and opportunities for heat recovery. Balancing heat loads VRV s modular approach also provides greater flexibility to balance heat loads in different parts of the building. The IES modelling tool offers designers the ability to balance heat loads in different parts of the building, allowing them to choose the indoor unit style and capacity to meet requirements. Over 120 different indoor units available Indoor and outdoor units can be 90m distance in height No need to use additional kits and extended piping lengths The VRV outdoor unit can be used for indoor installation with ducting. 5 VRV For Large Scale Buildings

7 Commercial landlords Putting you in control In a harsh economic climate, where many office spaces remain empty for months on end, properties must be marketable to attract the right kind of tenant. Efficient building services, combined with intelligent building controls, promise smart use of energy that forward thinking businesses expect and demand. Heating, air conditioning, hot water and ventilation are all significant areas of energy consumption. But neither the commercial climate, nor the current legislative framework, will tolerate wasted resources. So landlords need to prove a property s energy efficiency credentials to secure the most lucrative tenancy agreements. Precise zone control The VRV system provides precise control of both small and large areas, offering individual control of over 5,000 indoor units using the latest control technologies. Zone by zone control offers lower running costs, because the system can be activated only in rooms that require heating or cooling, and can be shut down entirely in rooms where no air conditioning is required. Smart energy management Smart energy management tools maximise efficiency by reducing running costs and preventing energy waste. From individual systems to the management of multiple buildings, Daikin has a control solution for every application. Multi tenant function If one part of the building is closed or being serviced, VRV s multi tenant function ensures that the entire system doesn t shut down when the mains power supply of an indoor unit is switched off. In contrast, a chiller runs an entire system, which requires an expensive backup unit. So if it fails, the entire system fails. A low maintenance solution If a variable refrigerant system such as VRV has just 10% less refrigerant than the optimal amount, the power consumption to maintain capacity can rise by 40%. The Daikin system: Has automatic refrigerant charging and containment that ensures optimal capacity and efficiency while complying with F-gas regulations Maximises efficiency Minimises maintenance. Reliability you can depend on Of course, ensuring lower running costs depends on system reliability and efficiency over its entire lifetime. So it s reassuring to know that Daikin has an unparalleled reputation for quality and reliability. Our Solutions 6

8 Changing building performance for good Heating and climate control solutions can account for up to 50% of a building s CO 2 emissions. That s why energy efficient climate control solutions have such an important role to play in reducing running costs and carbon emissions from our built environment. Staying current with Building Regulations Changes to Building Regulations propose that CO 2 emissions for new non-domestic buildings should be reduced by either 11% or 20% over 2010 levels. Increased standards will also come into force for existing buildings. A 20% reduction is expected to require the use of integrated renewable energy technologies. This requirement will increase further when zero carbon standards are introduced for new non-domestic buildings from However, it is anticipated that costs incurred by these measures will be offset by fuel bill savings. The carbon challenge The Climate Change Act 2008 set the target of achieving a minimum 80% reduction in legislated greenhouse gas emissions by 2050, compared with 1990 levels. This transformation to a low carbon economy will be a defining challenge over the next generation, driving ever-stricter building regulations and EcoDesign legislation, combined with financial measures, to incentivise improved energy performance. Meeting planning targets Throughout the UK, central planning guidance now requires local planning authorities to adopt tougher planning policies. These are driving ambitious CO 2 reductions and the Merton Rule : a planning policy requiring new commercial buildings of over 1,000m 2 to generate at least 10% of their energy needs using on site renewable energy equipment. In London, the targets are even higher. The London Plan advocates that all major development proposals reduce CO 2 emissions by at least 20% through the use of on site renewable energy generation. So choosing renewable solutions isn t just a nice to have, it s a must have for any significant development scheme. Designing for BREEAM Many organisations now use BREEAM as the mandatory design standard to ensure that construction and refurbishment projects meet exacting requirements for CO 2 emission reductions. Property agents use BREEAM to promote a building s environmental credentials and benefits to potential purchasers and tenants, while developers can use BREEAM as a tool to aid Building Regulation compliance. Heat pump technology can help achieve higher BREEAM ratings, by delivering energy efficient and controllable heating. Specific credits can be given for integrated services and building management systems and further awards for innovation are also possible, based on the system design. Ahead of the efficiency curve The Energy Related Products (ERP) Directive, which came into force in January 2013, has specified new minimum EcoDesign requirements for air conditioning products. These aim to close the significant gap that often occurs between anticipated and actual performance, by measuring the real life energy efficiency of systems over an entire cooling or heating season. While the new ERP Directive only affects air conditioning products with a capacity of less than 12kW, from 2015 it is expected to affect systems suitable for larger buildings too. Daikin has already incorporated many of these EcoDesign requirements into the new VRV range. 7 VRV For Large Scale Buildings
