CO Monitoring Systems for Your Underground Garage

Presently, exhaust fans in the underground garage of your building should be running 24 hours a day, seven days a week if you do not have a Carbon Monoxide Monitoring System installed. Contrary to popular belief, it is a violation of the building code for exhaust fans to be cycled or shut down at any time during the course of a day unless there is a CO Monitoring System in place. Section 6 of the Ontario Building Code states that an enclosed storage garage should have a) a mechanical ventilation system to limit the concentration of carbon monoxide to not more than 100 parts per million of air or b) provide, during operating hours, a continuous supply of outdoor air at a rate not less than 3.9L/s for each square metre of the floor area.

If your fans are running 24 hours a day for seven days a week it is possible that the implementation of a CO Monitoring system could generate savings for the corporation. In this case paybacks are generally between 2 to 4 years. The incentive is double that of lighting retrofits - CO Monitoring systems garners an incentive of $0.10kWh.

Building Automation System Take–Overs

Not all Building Automation Systems (also known as Energy Management Systems) are the same. There is a wide range of manufacturers and installers with different control abilities.

As part of our free energy assessment, we often inspect existing Building Automation Systems. Regardless if the Building Automation System was installed during the construction of the building or if the System was installed as a retrofit, there are often areas that are either not controlled or not controlled very well. In many cases, the existing Building Automation System can be upgraded via the implementation of additional Variable Frequency Drives and leak/flood detection.

Provident Energy utilizes a Siemens Apogee Building Automation System that can be remotely accessed via the internet. Most Building Automation Systems are owned by the Condominium Corporation and they are free to choose any Energy Management company to monitor their system. The take-over should not involve a full re-installation of the Building Automation System. For any System, the main control panels can be replaced and in most cases the existing wiring, sensors and conduits can be re-used (the initial wiring is generally the most costly and labour intensive step).

As mentioned earlier, we find many existing Systems leave room for improvement. For example, the Domestic Hot Water System may have a flat temperature set-point for the entire day and night. Or, the make-up air handling units may have VFDs that fluctuate only between 85% and 95%, 24 hours per day – whereas these units could be slowed down during non-peak hours. Provident Energy can implement additional control algorithms for existing Building Automation Systems and we can usually enhance overall energy savings by 4%-7%.

Another important feature of Provident Energy’s Building Automation System is our Monitoring Service. Your building’s system will be monitored 24/7 offsite by Provident Energy’s team of highly skilled technicians for both critical systems alarms and overall system optimization. This ensures that any issues that may arise within the buildings critical components will be diagnosed by technicians and relayed back to the site staff. Early diagnosis of such issues helps to prolong the life of your critical components, and also helps to ensure that the residents comfort isn’t compromised in the process.

What incentive rebates are available for common area retrofit projects?

(Excerpt from Condo Business Magazine Online (part of the REMI network). Click here for the full article.)
 

There are several electrical and natural gas incentives available for energy-saving retrofits. Some of these incentives can provide a condominium with a rebate of up to 50 per cent of the project costs.

If a condominium is interested in electrical savings, the saveONenergy programs are offered through local utilities and are funded through the Ontario Power Authority (OPA). A wide variety of retrofits qualify under saveONenergy, including lighting, carbon dioxide monitoring systems, controls, building envelope, variable frequency drives and building automation systems.

There are three different streams for the saveONenergy retrofits. The prescriptive option allows a condominium to simply select from a list of measures that come with a matching per-unit incentive. Through the engineering and custom tracks, lighting retrofits are generally eligible for $0.05 per kilowatt-hour saved and non-lighting retrofits are eligible for $0.10 per kilowatt-hour saved.

If a condominium is interested in natural gas savings, Enbridge offers incentive rebates for retrofits such as variable frequency drives or building automation systems. Upon the successful implementation of an eligible project, customers may receive an incentive payment based on a rate of $0.10 cubic metres of natural gas saved.

The incentive application process for saveONenergy and Enbridge are similar: the retrofit project must be approved prior to implementation. A condominium’s application and specifications will be reviewed by an incentive program technical advisor to ensure the retrofit meets the program requirements. Once the retrofit project is complete, additional documents and site visits are required.

Understanding all the fine print of the incentive programs can be confusing but most energy efficiency contractors will assist with the incentive application process as part of their scope of work. Make sure to ask the contractor to estimate the anticipated incentive and clarify who is responsible for the applications. Although incentives have been available for years, it is surprising how many condominiums are still not taking advantage of them.

Lighting - Where to Begin?

Many Condominium Corporations think of lighting as the easiest way to attain savings on a large scale. The obvious reason being the fact that the majority of the lights in a Condominium must remain on at all times, or do they? This question and several others will be addressed in this article.

Energy Conservation Through Building Automation Systems

(excerpt from Condo Business Magazine's Green Issue, April 2012)

With a growing demand for energy conservation and a reduction in operating costs, condominiums are always searching for energy saving methods. Energy efficiency in high-rise multi-residential buildings can be achieved through a variety of retrofits including lighting, variable frequency drives, carbon monoxide monitoring systems, and occupancy sensors. However, one method that is often overlooked is the use of an Energy Management System (EMS) or Building Automation System (BAS) – these are systems that can improve energy efficiency within the building’s mechanical plant.

What is a building automation system?

A mechanical plant is a complex system of boilers, chillers, pumps, valves, and fans that provides heating, cooling, ventilation, and water throughout the building. When the building systems are functioning properly, residents won’t notice them, but when they're not, they can cause a lot of complaints – just imagine the last time there was no hot water in the building.

A building automation system allows for control and integration of the building plant. By scheduling, adjusting, and monitoring the major mechanical plant equipment, the system will become more efficient, reduce energy consumption, and reduce operating costs all without sacrificing resident comfort. The mechanical systems are generally set to meet the highest demand expected for a given season and not necessarily the actual demand at a given time. Essentially, the different elements of mechanical equipment are designed to run at full speed and power at all times which can result in wasted energy consumption. Although most building automation systems are designed primarily for HVAC (heating, ventilation, air condition) control, many systems can also incorporate additional functions, such as lighting control, computerized maintenance scheduling, life-safety functions, and security access control.

The biggest benefit of a building automation system is energy savings. Most engineering sources estimate that the total energy savings to between 5-15% of the building’s annual energy consumption. This means thousands of dollars in annual savings.

Make Up Air Units and Variable Frequency Drives

Corridor Fresh Air Units or Make-Up Air Units (MUA) are found in virtually all High Rise Multi-Residential Buildings. Older buildings, including rental properties, often have these units with no heating or air conditioning of the air introduced into the building. In newer buildings and in virtually all condominiums, these units do provide heating and cooling of the fresh air.

The purpose of the MUA units is threefold. First, the units slightly pressurize the building in order to prevent infiltration of outdoor air through the building envelope. Second, the units provide, as the name implies, ‘make up air’, to replace air that has been exhausted from the building by in suite exhaust fans. The third purpose is to provide for ‘air changes’, or fresh air for comfort and respiration.

The Canadian Mortgage and Housing Corporation (CMHC) have done numerous studies on make up air units, and have found some very interesting results. One of the things that were found was that this air often leaks through the building envelope in unintended ways.Air can leak through door openings, envelope penetrations, elevator shafts, stairwells, and other places where the air can find its way directly to the outside. The result is that Fresh Air Units can be tremendous energy ‘wasters’. When fans are sized during the construction phase, they are often sized using the assumption that a certain number of exhaust fans will be running at the same time. This is referred to as the diversity factor. Clearly, at night and at other off-peak times, the actual use of exhaust fans will be well below the diversity factor used to size the fans.

One excellent solution is the use of Variable Frequency Drives (VFD). The fan can be operated on a time of day schedule, speeding up and slowing down as needed. Variable Frequency Drives today are much more reliable than they have been in the past and their increased use has driven installation costs down. Provident Energy has supplied and installed hundreds of VFDs and we highly recommend their use in a wide range of applications.

For more information regarding VFD applications for your building or to arrange a free energy assessment, please contact the sales department at Provident Energy at 416-736-0630, extension 5.

Incentives Paying You to Save Energy

The number one ongoing cost for any condominium corporation, is the cost incurred through the consumption of energy. The OPA (Ontario Power Authority) is providing the funding for local utilities to provide a new set of incentives to help multi-unit residential dwellings facilitate energy efficient retrofits. This incentive program will be available from March 2011 through to 2014. The new Save ON Energy program follows many of the same guidelines of previous incentive programs, except for a few key differences. Instead of providing $0.07 per kWh or $400/kW in demand reduction for lighting retrofits they will be providing the greater of either $0.05 per kWh or $400/kW with a maximum of 50% of the retrofit cost being covered by the incentive, which is up from the previous cap of 40% (for custom and engineered track). For non-lighting retrofits an incentive of either, $800/kW or $0.10/kWh of first year electricity savings to a maximum of 50% of project costs.
