1 Inflector Solar Shades Radiant Heat Barrier

2 Inflector Solar Shades Developed from NASA technology WHAT ARE INFLECTOR SOLAR SHADES? Inflector Solar Shades are a unique, energy saving product that acts as a solar filtering, reflective thermal shade. They stabilise the indoor temperature by reflecting or absorbing solar heat and blocking up to 92% UV while allowing natural light and providing a safer, more comfortable environment. They also significantly reduce your energy bills. VISIBLE LIGHT SOLAR HEAT WINDOWS TRANSFER HEAT Windows are the weakest part of the building envelope and account for heat gain, within a building, in the summer and heat loss in the winter. Heat gain increases cooling costs and heat loss increases heating costs. A single pane clear window is 20 times less energy efficient than the wall area they replace; and double pane Low-E windows are 10 times less energy efficient than the wall area they replace. This means that on average a building can lose more than 30% of its heat or cooled air out through its windows. While the amount of heat loss or heat gain through windows depends on whether the windows are single pane glass, clear double pane, Low-Emission coated, or gas filled, the fact is if you have windows you have heat gain and or heat loss every day of every year. ULTRAVIOLET Inflector works all year by keeping heat in the building during winter and keeping it out during the summer. Thereby permanently reducing your energy bills. Inflector works to save you energy in three ways: Reflectivity - Reflecting solar heat gain back out. Emissivity At most, Inflector only emits 5% of the radiant heat. Absorption - Inflector s dark reverse side absorbs heat from the sun in winter and re-radiates it into your building, resulting in lower heating costs Inflector Solar Shades are uniquely engineered to provide solar filtering and offer a range of installation options to suit each individual building s interior design. The reflective thermal shades aid in stabilising indoor temperatures by allowing natural light in reflecting solar heat and UV to create a safer, more comfortable environment along with lower energy bills. WINDOWS 75 % BUILDING HEAT LOSS/GAIN ROOF 10 % WALLS 6 % INFILTRATION 5 % FLOORS 4 % Inflector Solar Shades are the result of many years of research and development, refined into the product we offer you today. Commercial buildings HVAC loads account for about 63% of all Australia s carbon emissions. 2

3 Innovative Window Insulation Technology A passive solution which addresses more than just the reflectance of solar heat gain. HOW DO WINDOWS TRANSFER HEAT? Windows lose and gain heat through a combination of four factors: Conduction - The direct transfer of heat through the materials of the window. Radiation - Infrared energy transmitted through the glass. Convection - Air gives up its heat to the cooler glass and sinks towards the floor. This sets up air currents that draws warmer air to the glass that is in turn cooled causing a draft. Air Leakage - The passage of heated air through cracks and gaps in the window fitting. Inflector Solar Shades address all of the problems caused by windows in building heat loss and gain. Inflector controls reflectivity, emissivity, absorption, radiant heat gain, solar heat gain, privacy, infiltration, condensation and heat loss in the winter Inflector acts as a passive solar collector, absorbing sunlight and radiating free heat into the building.

They are where you lose heat in winter and gain heat in summer. 3

4 Seasonal Effects on Buildings Heating and cooling systems can account for over 50% of the overall energy consumption in office buildings. Summer In summer windows provide desirable daylight and a view, but also allow in ltration, unwanted glare, heat gain and damaging UV rays to enter buildings. This results in: y increased greenhouse effect y increasing interior temperatures y high cooling/air conditioning costs y decreasing comfort and reduced worker productivity y UV damage to furniture, carpets, etc. Winter While windows allow daylight and solar gain which we want in the winter they also allow the sun s damaging UV rays to enter through the windows. Additionally, heat escapes through the windows when it is colder outside than inside. There is also heat loss due to ex ltration (air leakage).

5 Inflector Solar Shades during Summer months Inflector Solar Shades offer an immediate reduction in energy costs and a return on investment of years. Inflector Solar Shades address all deficiencies of the building envelope pertaining to windows. The shades effectively give beneficial control over reflectivity, emissivity, absorption, radiant heat gain, solar heat gain, privacy, in ltration, and condensation; as well as being a passive solar collector, absorbing sunlight and radiating free heat into the building. Summer Benefits & Value In the summer the Inflector Solar Shades are positioned so that the silver side faces out which: y reflects 72% of radiant heat back out through the window (reducing the greenhouse effect in buildings) y reflects 65% of solar gain back out through the window (reducing overheating in buildings) y reflects 92% of damaging UV rays back out through the windows (reducing fading & sun damage) y reduces cooling requirements saving energy, CO2 and money y controls glare (especially for computers & televisions) y provides daytime privacy (one way vision) y provides cool day lighting with a view y reduces the load, wear, & maintenance on HVAC units In Summer Inflector Solar Shade reflects ultra violet rays and solar heat Window glass Infector Solar Shade Inflector Solar Shade allows daylight to pass through Solar heat reflected from a building due to installing Inflector Window Type Percentage heat coming through the window Without Inflector With Inflector Incoming heat reduction using Inflector Single Pane 85% 17% 80% Double Pane 70% 15% 78.8% Double Pane Low- E 54% 13% 75.9% 5

6 Inflector Solar Shades during Winter months Inflector Solar Shades act as a solar collector in Winter, radiating heat into the buildings thereby reducing heating costs. Winter Benefits & Value In the winter the Inflector Solar Shades are reversed so that the silver side (aluminium) is facing inward to reflect the thermal heat back into the building and reduce heat loss through the windows. Windows with direct exposure to the sun become passive solar collectors with the black side of the Inflector absorbing the sun s rays and radiating the heat inward. For example a 1.5m 2 window with an inflector panel in direct sunlight can produce 2,096 BTU s of heat per hour, which is equivalent to a 600 watt electric heater. y damaging UV rays are reflected back outside y the load, wear, & maintenance on HVAC units is reduced y reduces heating requirements saving energy, CO2 and money In Winter Inflector Solar Shade reflects ultraviolet rays Inflector Solar Shade allows daylight to pass through Window glass Infector Solar Shade Inflector Solar Shade reflects interior heat back into the room Inflector Solar Shade allows solar heat to pass Live Trial Dunning Avenue Rosebery, Sydney NSW Australia The attached graph is a representation of a live office trial in Sydney where two identical offices faced due north with the exact same square meterage of glass exposed to direct sunlight. The trial was on the 17th & 18th of February The temperature differential shows a 33% reduction in solar heat gain at the hottest part of each of the days. 6

7 Inflector Application More cost effective & energy efficient than replacing the windows or window treatments. The Inflector Solar Shades will be of particular interest to commercial property owners, property management companies & facilities managers looking to lower energy costs and increase the thermal comfort within their buildings. They offer: y increased occupier comfort and reduced complaints y tenant retention due to more usable space eliminates hot and cold spots y updates building appearance without changing the overall exterior appearance y rapid return on investment shades and the row of style block-out shades above. The block-out shades simply heat- up and radiate the heat into the building adding to HVAC demands and worsening the occupants thermal comfort. Inflector has been installed in a variety of buildings across the Australia including, NSW Police, Narellan Library, Lismore Workers Club, Aeris Environmental & Ballina RSL. Installation Options Inflector can be installed as either a roller blind as in the library opposite, a fitted screen as shown below or as a vertical blind shown overleaf. The internal and external pictures of the window demonstrate how Inflector provides daytime privacy for the occupants within the building without significantly compromising their view. Configured as vertical blinds it provides the easiest switch from silver to black, dependent on the season and offers a very effective retrofit option to any existing standard vertical blind installation. Inflector Solar Shades are a proven alternative to window replacement offering a more cost effective, energy effcient and significantly less disruptive option.

The higher the numer, the more light is transmitted. y Total Solar Energy Rejection of both solar and infrared energy rejection. The total amount of solar energy (heat gain) rejected by the window film when installed. The higher the number the more heat and infrared is being rejected. 9

10 Case Study - Regional Health Care Group Regional Health Care Group has north facing windows that attract solar heat gain all year round. As part of ENSOL Systems proof of concept. Regional Health Care Group allowed ENSOL to monitor two of their upstairs offices. One office was fitted with Inflector while the other had tinted glass. The offices were both the same size and orientation, with identical air conditioning control. A week long trial in March 2016 showed a consistent temperature difference of 5-7 C. The office fitted with Inflector had the lower temperature as shown on the graph below. Temperature Sensor Results Inflector On Glass Tint 10

11 Case Study - Lismore Workers Club The Lismore Workers Club, built in the 1970 s, has a front facade with three stories of glass frontage. This glass created heat load issues for the entrance and reception. On very hot days the heat load created considerable discomfort for the staff and heat problems with the automatic doors. The installation of an additional 30kW air conditioner had negligible effect. ENSOL Systems investigated the problem and then installed reduction of the heat load, UV and glare. Since the Inflector window insulation project has been completed though, the front door area of the Club has a much improved climate for both staff and patrons. The heat transfer barrier has markedly improved working conditions for staff and the ambiance of the welcoming process for patrons. For the first time it feels that the air conditioners for this area are actually doing their job!
