Traditional HVAC Systems:

As we know traditional standard 4-pipe fan coil systems require domestic cold water, domestic hot water supply, domestic hot water return, heating water supply, heating water return, chilled water supply and chilled water return for a total of seven pipes. 2-pipe fan coil systems require five pipes; domestic cold water, domestic hot water supply and return – space heating water supply and return. In the cooling season, the heating pipes “changeover” to chilled water. Radiant baseboard systems have five pipes. Water source heat pumps have five pipes. Variable refrigerant adds refrigerant piping and controls plus the cost of electrical.

IPS Logic:

The Integrated Piping System (IPS™) adds a single pipe for a total of four (4) pipes; a domestic hot water supply & return, along with a domestic cold water supply & return. IPS^TM is TWO IN ONE domestic water based mechanical system which has ONE Piping Distribution System, ONE Central Heating & Cooling Plant and uses Williams IPS fan coil in the system as HVAC fixture.

IPS Risers:

4 pipe risers can be reduced to 3 pipes or 2 pipes subjected to system temperature requirements. Fan coil can be shipped with or without copper risers.

Domestic hot/cold water distribution to suite plumbing fixtures can be copper or PEX tubing that can embedded in concrete slab connected to main fan coil risers.

IPS Fan Coil:

With IPS"! from Williams, your building’s domestic water service is also used to supply heating and cooling water to fan coil units located in each room, suite or office. Each IPS fan coil unit contains essential features specifically designed to work with IPS and is equipped with an individual thermostat allowing each occupant to have complete control of his/her environment. Also IPS™ fan coil unit is equipped with a circuit board that opens the heating and cooling valve every 24 hours to eliminate stagnation.

IPS Central Plant:

By utilizing the domestic water system - which is already managed to the optimum water temperature for space heating by code - IPS takes full advantage of the “central system” saving thousands of dollars in dedicated space heating piping and equipment such as boilers, pumps and storage tanks. Plus, managing the cold water temperature for space cooling opens up the opportunity for energy efficiency, heat recovery and economizer cooling (Reduce, Recycle & Reuse)..

IPS central heating and cooling system could be efficient chiller, condensing boiler, biomass plant, geothermal system with central water to water heat pumps, air source outdoor heat pumps, solar etc……

IPS Temperature Ranges:

Heating Mode: IPS™ central plant delivers domestic hot water (DHW) at 120oF and return it at 105oF or in some cases supply 140oF water and return it at 120oF. For application where DHW supply temperature is at 140oF, thermostatic mixing valve (TMV) will be provided (by others) either at each fan coil location or discharge side of central DHW tank to prevent scalding at the plumbing fixtures.

Cooling Mode: IPS™ central plant delivers domestic cold water (DCW) at 45oF to 50 oF and return it at 55oF to 60 oF or in some cases supply 40oF water and return it at 55oF.

IPS Controls:

It is important to note that with IPS™ controls are relatively simple, giving a peace of mind to building operator as they can operate the building proficiently without going into excessive system training.

IPS Code Compliance:

Potable water for domestic use & water for heating & cooling with IPS™ remain 100% isolated from non-potable devices as per local plumbing codes. Since IPS™ is a domestic water system, no water treatment is necessary. Fresh water is introduced to the system daily.

The IPS™ fan coil unit is equipped with a circuit board that opens the heating and cooling valve every 24 hours to eliminate stagnation. This means the safety & integrity of the building’s potable water system is never compromised & water is safe enough to drink without creating any health hazard issues.

Moreover, when properly designed, IPS satisfy national and local code requirements.*

* Local code requirements should be consulted and adhered to. ABS & Williams are not responsible for final design approval.

In general, IPS system works on ONE Central Heating & Cooling Plant which uses domestic hot and cold water risers (ONE Piping Distribution System) to provide heating and cooling for space with IPS fan coils as HVAC fixture and the domestic hot/cold water distribution to suite plumbing fixtures via PEX tubing embedded within core slab or concrete layers of a building resulting in complete elimination of central HVAC heating system such as natural gas boilers, pumps, piping, controls etc.; reduces the number of pipes of HVAC cooling system; require relatively smaller mechanical room etc., ultimately reduces the total number of pipes, labor, equipment & space which in the end reduces overall cost of the project.

Established IPS™ system with more than a decade track record of outstanding performance reveals that with IPS™, approximately on an average, $15/sq. ft. installed costs & operating costs of $0.7 to $0.85/sq. ft. are very attainable versus a more traditional HVAC systems. This also means that IPS™ saves upfront capital cost approximately from $3000.00 or MORE per suite on a typical high rise condominium building and it can be 20% to 60% MORE efficient versus traditional HVAC systems.

Is IPS! Right for My Building?

Tight budgets, increasingly strict environmental regulations and an appetite for innovation have created the ideal conditions for a fresh look at cooling & heating systems. If you haven’t yet worked with INTEGRATED PIPING SYSTEM (IPS), there’s a good chance you will in the near future.

IPS concept was introduced in year 1999, since then it has been installed in over 130 projects in the United States & Canada from Salt Lake City, Utah, British Columbia to Edmonton City of Alberta, which is where it started.

Lauded for its energy efficiency, low capital cost and low maintenance post-installation, it’s a technology that more & more builders are considering, including the team that built high profile “THE DOCKSIDE GREEN COMMUNITY” project in Victoria, BC and now QUEENSTON QUARRY team sees value too in IPS technology.

With the success of IPS projects, we expect more engineers, architects & builders will consider HVAC system featuring IPS based designs.

If you already have hot and cold water distribution throughout your building, then you’re probably an excellent candidate for IPS"!!

By taking advantage of the existing piping infrastructure and domestic hot/cold water already in the building, the costs associated with establishing this impressive and reliable hydronic heating and cooling system are significantly reduced.

It’s important to remember that with IPS"!, potable water for domestic use and water for heating and cooling always remain 100% isolated from non-potable devices. This means the safety and integrity of the building’s potable water system is never compromised in any way.

IPS Cutting-edge technology work seamlessly with Geothermal, Solar, Biomass District or Central systems to make any project a model of Eco-Friendly Design.

Projects such as limited service, suite and extended stay hotels, lodge, resort, senior care, assisted living centers, condominiums, dormitories, apartments, army barracks, schools and many more…. are most often ideal for an IPS"! application.

Together we can make a difference!

The principles of Eco-friendly Environment, New Urbanism, Smart growth, green building and sustainable community design are all essential elements of our offering to create a dynamic environment where kids, residents, employees, neighbouring businesses and the broader community will interact in a healthy and safe environment.

LEED-friendly energy savings

With the application of terminal unit systems, efficiency drops because terminal units cycle at purchased horsepower and at a higher dollar per ton for equipment. The “lower cost per ton” central plant advantage and heat recovery employed by IPS means operating costs are consistently more attractive, especially when compared to traditional HVAC systems available today.

The benefits of a hydronic system, along with fewer materials, lower heating and higher cooling water design temperatures and heat recovery, make IPS"! one of the most efficient and affordable options available today.

IPS is up to 70% more efficient than packaged terminal units, up to 40% more efficient than 2-pipe hydronic, WSHP or variable DX systems, no compressors or equipment in the occupied space and reduced electrical power.

As a result of the innovative technology utilized in the IPS energy efficient mechanical systems, we can assist developers in qualifying for a significant portion of available LEED Points in the following areas:

• • Water Efficiency


• • Energy & Atmosphere


• • Indoor Environmental Quality


• • Innovation and Design Process


• • Regional Priority

IPSgeo impact 45 LEED points under LEED 2009 for New Construction and Major Renovation.

According to NRCan this neighbourhood development plan is one of the first in the world to achieve LEED Platinum. Many buildings on this project achieved 10 points in Energy & Atmosphere Credit 1 under LEED NC 2004.

LOW LEAD REQUIREMENTS

For suggested building types, when considering installed costs, operating costs, system efficiency and return-on-investment comparisons with competitive systems, the advantage goes to IPS"!. At right are general comparison charts that show how IPS"! stacks up against the competition.

Installation Costs vs. Comfort

While 4-Pipe Hydronic Systems provide a superb level of comfort, installation costs are usually a bit higher than most due to the system’s piping requirements. Water Source Heat Pumps and 2-Pipe Hydronic systems are generally more affordable to install, yet sacrifice optimum comfort. Conversely, Packaged Terminal Air Conditioners are relatively inexpensive to install, however, are noisy and sacrifice comfort. Since IPS"! utilizes the heat transfer efficiency of hydronic space conditioning while capitalizing on the “central system” already in the building, the system is an ideal choice for maximizing installed cost-savings and comfort.

Operating Costs vs. Comfort

With the application of terminal unit systems, efficiency drops because terminal units cycle at purchased horsepower and at a higher dollar per ton for equipment. The “lower cost per ton” central plant advantage and heat recovery employed by IPS"! means operating costs are consistently more attractive, especially when compared to PTACs window unit.

System Efficiency vs. Comfort

The benefits of a hydronic system, along with fewer materials, lower heating and higher cooling water design temperatures and heat recovery, make IPS"! one of the most efficient and affordable options available today.

Return-on-Investment vs. Comfort

When considering the minimal piping and equipment requirement, energy efficiency and central plant advantage, IPS"! delivers an impressive return-on-investment.

For more specific system comparisons, see the document entitled “IPS System Comparisons” indicated on this page.

And the Winner is ...IPS!

The core of IPS! and it’s energy efficiency is the central plant advantage!

Reduced capital costs, impressive energy efficiency and a 12-years record of success make IPS! the right system for qualified applications. With IPS!, $15/sq. ft. installed costs and operating costs of $0.75 to $1/sq. ft. are very attainable.

Luxurious Comfort with IPS at a cost of PTAC system.

By utilizing the hydronic system already present in the building, these capital and operating cost targets are achieved in a variety of areas:

Less pipe required

unlike conventional hydronic systems that require as many as five pipes running throughout the building, IPS"! requires the addition of only one cold water return pipe to satisfy HVAC requirements.

Elimination of heating-specific equipment

By utilizing the domestic water heating-related equipment and distribution system for space heating, the need for surplus, dedicated equipment is eliminated.

Associated equipment reduction

these costs – sometimes referred to as “interface costs” – are all costs associated with the installation of a second set of pipes. They include surplus building space, fittings, valves, chases, insulation, hangers, various treatments along with management and maintenance.

Reduced labor costs

labor costs associated with all the above is either greatly reduced or eliminated altogether.

Central plant advantage

When terminal systems are applied to any application, efficiency drops due to units cycling at purchased horsepower rather than the demand in your building. And all at a higher dollar-per-ton cost for equipment. The fan coil system can be up to 70% more efficient than unitary based systems.

Hydronic transfer means superior efficiency

Since moving BTUs in water is vastly more efficient than moving them in air, experts agree that hydronic heating and cooling is one of the most comfortable and energy-efficient methods for space conditioning.
