RACUS® ceiling tiles are installed into new or
existing suspended ceiling grids as a like for
like replacement tile that are common place
in old and modern commercial buildings.
Incorporating the latest bio-based phase
change technology, the passive RACUS® tile
gives instant energy savings over HVAC
systems without on going maintenance or
replacement costs.
How Phase Change Materials (PCMs) Work
Phase change materials store energy in a latent form, undergoing an endothermic
process to store heat energy when ambient temperature rises and an exothermic
process to release this energy when the temperature drops. In building applications,
these processes occur within a narrow temperature range close to the human
comfort temperature with large amounts of heat being absorbed and released.

      As the internal room temperature                As the internal room temperature
    increases, the PCM core goes from a                cools, the PCM core goes from a
     solid to liquid state and in doing so            liquid to solid state , releasing the
       absorbs and stores latent heat.                         stored latent heat.


During the transition phases, the core of the microcapsule will melt as the room
temperature reaches the transition temperature and in doing so will absorb latent
heat where it will be stored until such time that the room temperature cools.

RACUS® Ceiling System
The RACUS® ceiling tile is designed to be incorporated into either an existing
suspended grid system as part of a commercial retrofit or new build project. The tiles
can be easily installed over a short period or out of hours so as to reduce the impact
on the building users and provides an instant solution to reduce the energy and
carbon footprint of the building.
As the tiles are not permanent fixtures
within the ceiling grid, the tiles can be
manoeuvred around the building to capture
areas of significant heat gains. This can be
around high glazed areas that suffer from
solar gain, above refrigeration units where
high heat gains are generated from the
motor to cool the unit or localised areas
such as meeting rooms with high
occupancy within offices.

It is often the case that the use of the
building changes, particularly regarding the
number of occupants. The result of which
would place a significant higher demand on
conventional HVAC systems. With the
RACUS® system, additional tiles can be
incorporated into the existing grid or
replaced with tiles with higher heat storage
capacities at a fraction of the cost of
upgrading or replacing HVAC systems

  • Passive system with no energy or long term maintenance and life cycle costs

  • Reduces the carbon footprint of the building through reduced energy costs.

  • High heat storage capacity.

  • Flexible

  • Non invasive to building users or equipment

  • Quick-fit solution
RACUS® Preformed Natural Mineral Tile
The RACUS® Preformed Natural Mineral Tile incorporates bio-based phase change
material to increase the thermal mass and latent heat storage capacity over
traditional mineral fibre tiles.


             The RACUS® Preformed Mineral tile are used either as a replacement
             tile for existing suspended ceilings as part of a retrofit project or as a
             complete system for new build construction.

             In addition to the heat storage capabilities, they have excellent
             hygroscopic characteristics, absorbing the excess humidity in the
             atmosphere, and then gradually restoring the balance in dry and hot
             periods and as such improving the atmospheric microclimate in the
             rooms.

             The tiles are supplied with the option of two latent heat storage
             capacities - 30Wh/m² and 65Wh/m² with a return of investment
             around five years. Also in a choice of surface textures and edge details
             including square or tegular.


             Our bio-based phase change material has been tested to over 45,000
             thermal cycles which is equivalent to a lifetime performance of over
             122 years without loss of performance and biodegradability testing of
             within 12 months compared to over 100 years for alternative paraffin
             wax based PCMs.


               The RACUS® Preformed Tiles
                   are 100% Recyclable
RACUS® Metal Ceiling Tile
Combining the performance of a metal ceiling tile with the ability to reduce the
energy and carbon footprint of a building through the incorporation of the RACUS®
PCM material, the RACUS® Metal Ceiling system is a passive solution that offers a
quality finish to new or existing suspended ceiling systems with a latent heat storage
capacity option of 85Wh/m² or 169Wh/m².

Through testing in thermal chamber testing and live exemplar projects, the RACUS®
metal ceiling tile has achieved up to 97% energy savings over existing HVAC systems
and a reduced room temperature of up to 7°C under zero ventilation conditions.




The RACUS® metal ceiling system is available as either a standard
plain metal ceiling tile or as a perforated tile where there is an
acoustic performance requirement. In both formats there is a choice
of latent heat storage capacities to meet the requirements of the
building.




 Passive Product of the Year
            2012
RACUS® ceiling tiles incorporating bio-
based phase change materials, allow
thermal mass to be incorporated into new
build and retrofit projects faster and more
economically compared to alternative
construction methods such as concrete,
both from a project cost and
environmental perspective.
Thermal Mass in Lightweight Structures
A thermal mass is a material that absorbs
heat from a heat source, and then releases
it slowly. In buildings, thermal mass is
provided by the structure of the building,
the level of which is determined by the
material the building is constructed from.
Buildings constructed of lightweight
materials such as steel or timber are not
considered to have good thermal mass
properties compared to concrete, brick and
stone for the reasons that they either have
low thermal conductivity performance
therefore a low ability to absorb heat, or
can absorb large amounts of heat but the
rate of heat release is also high. Concrete,
brick and stone are all materials that are
able to absorb and store heat until the
surface of the material is exposed to cooler
conditions and its temperature begins to
drop. When this happens, the stored heat
transfers to the cooler surface and is
released back into the building.




Stabilising effect of thermal mass on internal temperature – Source: The Concrete Centre
The ability to absorb and release heat in this way enables
buildings with thermal mass to respond naturally to changing
weather conditions, helping to stabilise the internal
temperature and provide a largely self-regulating
environment.

The role of a buildings thermal mass can be of benefit throughout the year. During
the warm weather in summer, heat will be absorbed by the thermal mass in order to
prevent overheating in the building, providing a more comfortable living or working
environment in naturally ventilated building or in air-conditioned building, reduces
the cooling demand on mechanical air-conditioning systems. Allowing cool air to
ventilate the building at night allows heat that has been stored throughout the day
to be removed.
This daily heating and cooling cycle works particularly well in countries such as the
UK where night time temperatures are typically around 10 degrees less than peak
daytime temperatures, making it an effective way of drawing heat from the structure
of the building. The benefits of thermal mass during winter when heating demands
are at their greatest, can help to reduce fuel consumption when used in a passive
solar design. In doing so, solar gains in winter, along with heat produced from
appliances, cooking, people and lighting, uses the thermal mass to absorb gains
which is then slowly released overnight as temperatures fall, helping to keep the
building warm and reducing the need for additional heating.
RACUS® Ceiling Tile Applications

Schools
Adopting an economic approach to the construction of school
buildings often results in the construction of lightweight structures
with very low thermal mass. This approach does not allow any high
heat gains to be absorbed by the thermal mass parameters of the
building.

In comparison to a typical office environment, classrooms have a higher density of
occupation which along with heat output from PCs, contributes to higher heat gain loads.
Thermal Mass can be improved using RACUS® ceiling tiles without the loss of internal floor
space.

Natural Ventilation is becoming increasingly popular in school design as a substitute for
mechanical ventilation systems but this only provides between 30 – 40W/m² . Combining
the RACUS® ceiling tile with natural ventilation system provides additional thermal comfort
of up to 169Wh/m² utilising a passive system



Commercial
The demand for air conditioning in buildings worldwide is growing
rapidly in response to increased building use and demands for
comfort cooling by occupants. As such the energy consumed by air
conditioning systems is expected to double from current levels by
2020 and already accounts for over 30% of a buildings total energy
use.
This increase conflicts with the Governments goals to reduce the UK’s total CO2 emissions
and makes it increasingly difficult for companies to meet its carbon reduction targets under
the Carbon Reduction Commitment.

A typical air conditioned building has double the energy costs and associated CO2 emissions
of a natural ventilated building as well as increased capital and maintenance costs. In the UK
there are relatively few days where the temperatures are very high, however using comfort
cooling for just this short period of time can cost as much as a whole years heating.
Incorporating the RACUS® ceiling tile into commercial buildings not only add thermal mass to
lightweight structures but will reduce the energy demand of existing air conditioning systems
by absorbing excess latent heat gains.
RACUS® Ceiling Tile Projects

Ofcom Head Office
As part of a project for facility management company
MITIE, the RACUS® ceiling tile was installed into one of the
meeting rooms at Ofcom’s London Head Office.

The performance of RACUS® was monitored and compared to an adjacent meeting room that
was both identical in size and layout and that used conventional fan coil units to manage the
room temperature.
In both meeting rooms, MITIE installed room three temperature loggers. One was to monitor
room temperature and two were installed on each of the FCU outlet grilles. These would
monitor when the FCU was providing heating or cooling to the room. The number of
occupants of each room and period of use was also monitored.
Monitoring was carried out over a 45 day period, the results of which concluded a 97%
reduction in the use of the fan coil unit in the room with RACUS®.

RACUS® Ceiling Tile Projects

Great Ormond Street Hospital (GOSH)
In August 2010, the RACUS® ceiling tile was installed into
one of Great Ormond Street Hospital’s consultation rooms
due to a serious problem of overheating.
The room, which is located on the lower ground level, is not serviced by any HVAC systems
and relies on only natural ventilation from the window and partial protection from solar gains
by a window canopy. Roller blinds have also been installed. Despite these measures, the
internal room temperatures have been reported between 30°C - 36°C.

                                               Prior to the installation of the RACUS® ceiling tiles, Facilities
                                               Management company MITIE installed room temperature

                                               be installed and also an adjacent and identical size consultation
                                               room, in order to capture baseline temperatures against which
                                               the performance of the RACUS® tiles will be compared.
                                               The existing suspended ceiling within the consultation room
                                               amounted to 64% of the total ceiling area. Of the total area, 32%
                                               of the existing tiles were replaced with RACUS® ceiling tiles.

The 600mm x 600mm, RACUS® ceiling tiles were pre-treated with an anti-microbial finish
and additional suspension hangers were also installed.

RACUS® Ceiling Brochure

  • 1. Passive thermal comfort from the most advanced phase change technology Datum Phase Change
  • 2. REDUCING AIR CONDITIONING UNITS & SYSTEMS RACUS® ceiling tiles are installed into new or existing suspended ceiling grids as a like for like replacement tile that are common place in old and modern commercial buildings. Incorporating the latest bio-based phase change technology, the passive RACUS® tile gives instant energy savings over HVAC systems without on going maintenance or replacement costs.
  • 3. How Phase Change Materials (PCMs) Work Phase change materials store energy in a latent form, undergoing an endothermic process to store heat energy when ambient temperature rises and an exothermic process to release this energy when the temperature drops. In building applications, these processes occur within a narrow temperature range close to the human comfort temperature with large amounts of heat being absorbed and released. Solid Liquid Solid As the internal room temperature As the internal room temperature increases, the PCM core goes from a cools, the PCM core goes from a solid to liquid state and in doing so liquid to solid state , releasing the absorbs and stores latent heat. stored latent heat. During the transition phases, the core of the microcapsule will melt as the room temperature reaches the transition temperature and in doing so will absorb latent heat where it will be stored until such time that the room temperature cools. Phase Change Material encapsulated in RACUS®
  • 4. RACUS® Ceiling System The RACUS® ceiling tile is designed to be incorporated into either an existing suspended grid system as part of a commercial retrofit or new build project. The tiles can be easily installed over a short period or out of hours so as to reduce the impact on the building users and provides an instant solution to reduce the energy and carbon footprint of the building. As the tiles are not permanent fixtures within the ceiling grid, the tiles can be manoeuvred around the building to capture areas of significant heat gains. This can be around high glazed areas that suffer from solar gain, above refrigeration units where high heat gains are generated from the motor to cool the unit or localised areas such as meeting rooms with high occupancy within offices. It is often the case that the use of the building changes, particularly regarding the number of occupants. The result of which would place a significant higher demand on conventional HVAC systems. With the RACUS® system, additional tiles can be incorporated into the existing grid or replaced with tiles with higher heat storage capacities at a fraction of the cost of upgrading or replacing HVAC systems • Passive system with no energy or long term maintenance and life cycle costs • Reduces the carbon footprint of the building through reduced energy costs. • High heat storage capacity. • Flexible • Non invasive to building users or equipment • Quick-fit solution
  • 5. RACUS® Preformed Natural Mineral Tile The RACUS® Preformed Natural Mineral Tile incorporates bio-based phase change material to increase the thermal mass and latent heat storage capacity over traditional mineral fibre tiles. The RACUS® Preformed Mineral tile are used either as a replacement tile for existing suspended ceilings as part of a retrofit project or as a complete system for new build construction. In addition to the heat storage capabilities, they have excellent hygroscopic characteristics, absorbing the excess humidity in the atmosphere, and then gradually restoring the balance in dry and hot periods and as such improving the atmospheric microclimate in the rooms. The tiles are supplied with the option of two latent heat storage capacities - 30Wh/m² and 65Wh/m² with a return of investment around five years. Also in a choice of surface textures and edge details including square or tegular. Our bio-based phase change material has been tested to over 45,000 thermal cycles which is equivalent to a lifetime performance of over 122 years without loss of performance and biodegradability testing of within 12 months compared to over 100 years for alternative paraffin wax based PCMs. The RACUS® Preformed Tiles are 100% Recyclable
  • 6. RACUS® Metal Ceiling Tile Combining the performance of a metal ceiling tile with the ability to reduce the energy and carbon footprint of a building through the incorporation of the RACUS® PCM material, the RACUS® Metal Ceiling system is a passive solution that offers a quality finish to new or existing suspended ceiling systems with a latent heat storage capacity option of 85Wh/m² or 169Wh/m². Through testing in thermal chamber testing and live exemplar projects, the RACUS® metal ceiling tile has achieved up to 97% energy savings over existing HVAC systems and a reduced room temperature of up to 7°C under zero ventilation conditions. The RACUS® metal ceiling system is available as either a standard plain metal ceiling tile or as a perforated tile where there is an acoustic performance requirement. In both formats there is a choice of latent heat storage capacities to meet the requirements of the building. Passive Product of the Year 2012
  • 7. RACUS® ceiling tiles incorporating bio- based phase change materials, allow thermal mass to be incorporated into new build and retrofit projects faster and more economically compared to alternative construction methods such as concrete, both from a project cost and environmental perspective.
  • 8. Thermal Mass in Lightweight Structures A thermal mass is a material that absorbs heat from a heat source, and then releases it slowly. In buildings, thermal mass is provided by the structure of the building, the level of which is determined by the material the building is constructed from. Buildings constructed of lightweight materials such as steel or timber are not considered to have good thermal mass properties compared to concrete, brick and stone for the reasons that they either have low thermal conductivity performance therefore a low ability to absorb heat, or can absorb large amounts of heat but the rate of heat release is also high. Concrete, brick and stone are all materials that are able to absorb and store heat until the surface of the material is exposed to cooler conditions and its temperature begins to drop. When this happens, the stored heat transfers to the cooler surface and is released back into the building. Stabilising effect of thermal mass on internal temperature – Source: The Concrete Centre
  • 9. The ability to absorb and release heat in this way enables buildings with thermal mass to respond naturally to changing weather conditions, helping to stabilise the internal temperature and provide a largely self-regulating environment. The role of a buildings thermal mass can be of benefit throughout the year. During the warm weather in summer, heat will be absorbed by the thermal mass in order to prevent overheating in the building, providing a more comfortable living or working environment in naturally ventilated building or in air-conditioned building, reduces the cooling demand on mechanical air-conditioning systems. Allowing cool air to ventilate the building at night allows heat that has been stored throughout the day to be removed. This daily heating and cooling cycle works particularly well in countries such as the UK where night time temperatures are typically around 10 degrees less than peak daytime temperatures, making it an effective way of drawing heat from the structure of the building. The benefits of thermal mass during winter when heating demands are at their greatest, can help to reduce fuel consumption when used in a passive solar design. In doing so, solar gains in winter, along with heat produced from appliances, cooking, people and lighting, uses the thermal mass to absorb gains which is then slowly released overnight as temperatures fall, helping to keep the building warm and reducing the need for additional heating.
  • 10. RACUS® Ceiling Tile Applications Schools Adopting an economic approach to the construction of school buildings often results in the construction of lightweight structures with very low thermal mass. This approach does not allow any high heat gains to be absorbed by the thermal mass parameters of the building. In comparison to a typical office environment, classrooms have a higher density of occupation which along with heat output from PCs, contributes to higher heat gain loads. Thermal Mass can be improved using RACUS® ceiling tiles without the loss of internal floor space. Natural Ventilation is becoming increasingly popular in school design as a substitute for mechanical ventilation systems but this only provides between 30 – 40W/m² . Combining the RACUS® ceiling tile with natural ventilation system provides additional thermal comfort of up to 169Wh/m² utilising a passive system Commercial The demand for air conditioning in buildings worldwide is growing rapidly in response to increased building use and demands for comfort cooling by occupants. As such the energy consumed by air conditioning systems is expected to double from current levels by 2020 and already accounts for over 30% of a buildings total energy use. This increase conflicts with the Governments goals to reduce the UK’s total CO2 emissions and makes it increasingly difficult for companies to meet its carbon reduction targets under the Carbon Reduction Commitment. A typical air conditioned building has double the energy costs and associated CO2 emissions of a natural ventilated building as well as increased capital and maintenance costs. In the UK there are relatively few days where the temperatures are very high, however using comfort cooling for just this short period of time can cost as much as a whole years heating. Incorporating the RACUS® ceiling tile into commercial buildings not only add thermal mass to lightweight structures but will reduce the energy demand of existing air conditioning systems by absorbing excess latent heat gains.
  • 11. RACUS® Ceiling Tile Projects Ofcom Head Office As part of a project for facility management company MITIE, the RACUS® ceiling tile was installed into one of the meeting rooms at Ofcom’s London Head Office. The performance of RACUS® was monitored and compared to an adjacent meeting room that was both identical in size and layout and that used conventional fan coil units to manage the room temperature. In both meeting rooms, MITIE installed room three temperature loggers. One was to monitor room temperature and two were installed on each of the FCU outlet grilles. These would monitor when the FCU was providing heating or cooling to the room. The number of occupants of each room and period of use was also monitored. Monitoring was carried out over a 45 day period, the results of which concluded a 97% reduction in the use of the fan coil unit in the room with RACUS®. 27 26 25 Temperature (°C) 24 23 22 Temperature 21 Difference of 20 4.33°C 19 Time (hh:mm:ss) Room without Room with RACUS® RACUS®

RACUS® Ceiling Tile Projects Department of Energy & Climate Change The RACUS® ceiling tile was installed into the Department of Energy & Climate Change (DECC) building as part of the TSB Energy Efficient Whitehall initiative. From a Dynamic Computer Simulated Model of the building which was completed by the Institute of Energy and Sustainable Development at De Montfort University, projected energy and carbon savings of over 55% were calculated. Zone Annual Normalised Zone Annual Normalised Cooling Annual Cooling Carbon Carbon Ceiling Type Energy Energy Emissions Emissions (kWh) (kWh/m2) (kgCO2) (kgCO2/m2) Conventional Tile 3177 128.6 1706 69.1 RACUS® 1441 58.4 774 32.35 Carbon Savings 932 37.7 Percentage 55% Saving Scaled across the total floor area of the building this would equate to an electrical energy saving of over 811,000kWh and carbon saving of 256 tonnes per annum. These figures are based using Defra 2008 CO2 conversion factor of 0.537kgCO2 per kWh of electricity and show a carbon saving (visual 14) of 37kgCO2 per m2.
  • 14. RACUS® Ceiling Tile Projects Great Ormond Street Hospital (GOSH) In August 2010, the RACUS® ceiling tile was installed into one of Great Ormond Street Hospital’s consultation rooms due to a serious problem of overheating. The room, which is located on the lower ground level, is not serviced by any HVAC systems and relies on only natural ventilation from the window and partial protection from solar gains by a window canopy. Roller blinds have also been installed. Despite these measures, the internal room temperatures have been reported between 30°C - 36°C. Prior to the installation of the RACUS® ceiling tiles, Facilities Management company MITIE installed room temperature monitors in both the consultation room in which RACUS® was to be installed and also an adjacent and identical size consultation room, in order to capture baseline temperatures against which the performance of the RACUS® tiles will be compared. The existing suspended ceiling within the consultation room amounted to 64% of the total ceiling area. Of the total area, 32% of the existing tiles were replaced with RACUS® ceiling tiles. The 600mm x 600mm, RACUS® ceiling tiles were pre-treated with an anti-microbial finish and additional suspension hangers were also installed. 30 28 26 Temperature (°C) 24 22 20 3.67°C 18 Difference 16 14 Time (hh:mm:ss) Room A Room B Outside (without RACUS®) (with RACUS®) Temperature
  • 15. RACUS® Ceiling Tile Projects BRE (Building Research Establishment) Victorian Terrace Located within Building Research Establishment’s (BRE) site Project in Watford, a disused Victorian terrace has been refurbished into three energy efficient spaces to fit 21st century living. The project aims to inform and provide guidance to the industry on how to contribute to the Government’s target to reduce CO2 emissions. Part of the development incorporates an information and training centre where visitors can learn best practice for refurbishment and about new and innovative materials. Within the presentation theatre, the RACUS® ceiling tile has been installed along with acoustic mineral tiles. “BRE recognise the significant impact that Phase Change Materials will have on the future design of our homes, both of new build and refurbishment. The use of the RACUS® product in our Victorian Terrace exemplar project here at BRE, will allow us to monitor the benefits in passive cooling, and the advantages of building thermal mass into existing structures to address climate change and reduced energy use.” John O’Brien, Principal Consultant, Refurbishment & Regeneration, BRE
