Energy Savings

International Solar Solutions Inc. undertook two separate and distinct methodologies to quantify potential energy savings:

1.     Scientific/laboratory testing

2.     In situation (on-the-roof) testing

 

Scientific/Laboratory Testing

The Canadian Centre for Housing Technology (“CCHT”) installed the SPAF units on one of two identical test houses with the other house representing the control sample. The units were left on the houses for two non-consecutive weeks in the summer of 2012; results indicated reduced air conditioner usage in the house with our SPAFs installed. This led to the creation of two formulae that allow calculation of kilowatts ( kW) and kilowatt-hour (kWh) savings as required by the Independent Electricity System Operator of Ontario  (“IESO”) and Ontario (electric) Local Distribution Companies (“LDCs”).  The test was corroborated at the University of Ontario Institute of Technology (“UOIT”) Automotive Centre of Excellence (“ACE”) facility through further experimental testing in the facility’s Large Climate Chamber. The results of the follow-up testing, when plugged into the formulae from the CCHT, yielded an approximate savings of 315 kWh per household per year with two units installed.

 

In Situation (on-the-roof) Testing

The in-situation testing was conducted over a 3 year period.  Data was gathered from 400+ homes across four Ontario LDC service territories – half of the homes had our SPAFs installed and the other half were used as baseline comparison homes and did not have a SPAF installed.   Energy consumption data was gathered by the LDCs themselves and provided to a data analysis and LDC program design firm called KMDR Research; the Principal of which is expert in the field of energy efficiency and has helped the former Ontario Power Authority (“OPA”) design their program evaluation protocols and subsequently conduct conservation program evaluation, measurement and verification.  KMDR research found:

“…a control-adjusted savings of 416 kWh per home was found using a quasi-experimental design, known as a Difference of Differences (DID) approach. By utilizing both methodologies of testing, we were able to identify the opportunity for energy savings and confirm the real-world benefits are actually better than what was initially thought from lab studies.”

Seasonal Effectiveness

Expert roofing professionals such as Ken Gascoigne, Owner/Operator of Empire Roofing Corporation – one of Ontario’s largest roofing companies advised the IESO the need for ventilation in the winter is just as critical as the summer:

"Contrary to the incorrect assumption that attic spaces should be warmer than the cold winter air outside, it is a fact that the attic space temperature should be the same as the outside ambient air temperature.  There should be no temperature differential between the inside attic space and the outside. When an attic space in the winter is warmer than the outside ambient air temperature, damage will occur ranging from mold to active condensation on the underside roof sheathing and structure. This is the single greatest cause of mold in the upper floors of residences.”

Insulation level effect on energy savings

International Solar Solutions contracted Kai Millyard Associates (a highly regarded insulation expert in Ontario) to provide an analysis of Ontario residential insulation levels by vintage to determine if insulation R-value of a house could affect potential savings created by SPAF technology.

The analysis indicates that the average insulation level across all vintages throughout Ontario is R-23. Their report clearly indicates that the SPAF would be beneficial for the vast majority of Ontario homes.

Effect of additional attic ventilation on air pressure in houses

International Solar Solutions contracted Gord Cooke of Building Knowledge Canada Inc., a well respected Ontario firm specializing in home energy and air-quality/air tightness audits, to request that Mr. Cooke opine on these concerns. The “Cooke report” indicates that a solar attic fan in particular would not create sufficient negative pressure to impact the operation of any natural draft combustion appliance nor would it create a an increased infiltration of radon gas. The negative pressure in the home would have to be 2-3 times more powerful than the SPAF to create any ill effects.  He states that this is the case for new and existing homes.

Again, in summary, the Solar Attic Fan system is unlikely to cause a negative pressure of 3-5 Pa in the attic of a home – new or existing. It is even less likely that it could create a negative pressure of 3 Pa. in the interior of a home. Properly constructed venting systems can reliably overcome negative pressures of up to 5 Pa. In new homes, power vented and direct vented combustion appliances can overcome 50 Pa of negative pressure or more.”

Affordability for Utilities (LDCs)

A Total Resource Cost (“TRC”) analysis was performed to identify the benefit/cost ratio that LDCs could expect if they to include the SPAF technology as part of an existing conservation program. The test was performed by Mike Singleton of SeeLine Group Ltd., an Ontario-based firm consisting of energy efficiency and conservation programming experts from various backgrounds including economics, engineering, business, and environmental sciences; SeeLine’s TRC protocol has been vetted and accepted by the Ontario Energy Board (“OEB”). The analysis, based on results achieved through the CCHT and UOIT experiments, concluded that the Solar Attic Fan would provide a benefit/cost ratio of +2.01. This is a successful result as anything above +1.0 is considered acceptable by Ontario LDCs as a cost effective inclusion in conservation programs.

Ontario Conservation First Framework LDC targets

Peter Love of Love Energy Consultants created a report for International Solar Solutions Inc. indicating approximate residential conservation targets by utility and what percentage of said targets could be achieved through inclusion of the SPAF in existing conservation programs. The report indicated that, on average, an LDC could expect to achieve between 8-10% of its residential conservation target through adoption of our SPAF technology. *Peter Love was Ontario’s first OPA Chief Conservation Officer, and is currently a professor of Sustainable Energy and Energy Efficiency Policy at York University, a long-standing advisor to MaRS, a founding board member of Rethink Sustainability and President of the Energy Services Association of Canada.

CoLLABORATIVE RESEARCH STUDY WITH Georgian CollegE

Barrie, ONTario, Canada

International Solar Solutions Inc. reached an agreement with Georgian College to study temperature differences between residential attic spaces with and without the Solar Attic Fan installed during the period of Nov. 2011 – Apr. 2012. The agreement provides for the opportunity to renew into an extended joint research program, which would study the various applications of the Solar Attic Fan and the associated benefits. Initial technical studies will be performed at the Barrie, Ontario campus. Phase two of testing will incorporate ‘test’ homes in/around the Barrie area and will focus on the collection of real world temperature and moisture reduction data. Along with sustainable energy and environmental students, phase three of testing will also include the Building and Design Departments for the construction of International Solar Solutions scale testing facilities. The study project will be partially funded by a grant from the Natural Sciences and Engineering Research Council (“NSERC”) of Canada. In addition to the grant, International Solar Solutions is pleased to provide incremental project funding, as needed, to assist Georgian College in aspiring to the highest possible standards of scientific research and innovation.
