Part 1: Problems with the City of Vancouver Zero Emissions Building Plan- 1 of 4

The Baby Get's Thrown Out with the Bathwater

Vancouver endeavors to be the greenest city in the world, and the city is attempting to create a new (theoretically) stricter building policy towards that end. Vancouver recently introduced a new Zero Emissions Building Plan in a 62 page report to council which they hope will become a zero emissions building code. It’s objective is to reduce emissions from new buildings by 90% by 2025 (compared to 2007), and have zero emissions in all new buildings by 2030. We will examine this plan in a 4 part series. 

Part 1- Creating a new plan when the old one seemed to have been working

Part 2- The district energy part of the plan. 

Part 3- The zero emissions  part of the plan. 

Part 4- The Passive House part of the plan. 

Part 1- Creating a new plan when the old one seemed to have been working

According to their own data, from 2007 to 2015 the city reduced their energy usage in buildings (through use of building codes etc) by 30% in new buildings and by 20% overall. In simple math that means if the City kept their current strategy their new buildings emissions will have been reduced by 55%. That's 35% off their new target to be fair but any strategy that is giving you a 2.5% yearly reduction would be a strategy one would build upon rather than abandon. Yet that is what City staff are proposing within the new zero emissions plan. 

The Current Standard

Vancouver’s current sustainable building standard for new buildings (requiring rezoning) is LEED Gold and ASHRAE 90.1-2010 for everything else that isn't a single family home. The LEED Gold requirement requires 22% better than ASHRAE 90.1-2010 which would suggest that if the City simply applied the rezoning policy to non-rezoning projects they might be well on their way to making up their 35% shortfall with their current plan of a 90% reduction by 2025. 

Both the USGBC who administers LEED and their partners at ASHRAE are constantly improving energy code standards as they have a similar goal as the City of Vancouver to have zero emissions buildings. The CaGBC also recently released their Zero Carbon Building Framework. 

Energy Standards Improvements

LEED and ASHRAE have unquestionably been the prevalent choice in the industry thus far with many cities adopting 90.1 and LEED as their standard before the City of Vancouver. LEED has such wide adoption because it is a holistic approach, addressing most issues of sustainable building such as energy efficiency, water usage, materials, transportation and location. On the other hand, Passive House has an astigmatic approach to sustainability, focusing only on energy savings. However energy and carbon savings savings can come in more forms that just your building using energy of one form or another. In a recent article, Tristan Roberts points out that 

The energy content of the gasoline used by the typical office commuter each year is comparable to the energy used by his or her share of the building where he or she works.

Which means that having good bicycle infrastructure in a building can have an greater impact on carbon reduction in the city of Vancouver than many building energy efficiency strategies. 

ASHRAE 90.1 for those who don't know is a building standard that has been around since the 1970's. Our national energy code is modeled on ASHRAE 90.1 and the standard covers a very wide variety of building types from residential, healthcare to super energy consumptive data centers. 

With the new Zero Emissions Building Plan, city staff appear to be pushing for Passive House or other building envelope standard to replace LEED for the city’s building standard by 2018 while simultaneously pushing district energy (or neighbourhood utilities as they call it) in new and existing building areas. 

Preview of Parts 2,3 and 4

The two largest problems with the City of Vancouver plan is that the city is pushing district energy at various levels (less efficient that building level systems) while the cost of natural gas is at an historic low. The one problem makes it technically more difficult to reduce carbon at a city level while the other makes it financially more difficult.

1. District energy makes meeting LEED and Passive House standards more difficult. The main reason is that both rating systems account for the inefficiency of district energy systems (line loss, pumping energy, etc) as they are both focused on more than just building efficiency. LEED accounts for it by making the baseline building cost the same as the proposed new building. City staff currently let people skirt this issue on code compliance models by not forcing them be the same value, thus allowing a design that would not qualify under LEED standards to pass at the city level so as to ensure that district energy is not seen as a penalty to developers who currently also have to pursue LEED Gold. Passive House accounts for the inefficiency of district systems by using source energy as their baseline for their energy intensity target. This means that you must also account for line loss, pump energy, and all the other factors associated with energy that is not produced on site. Should the city move away from LEED (not recommended) to Passive House the same allowance for district energy being used today would also be needed for Passive House buildings to meet their standard.
2. A wood based district energy systems would have to also ignore the embodied carbon associated with the diesel trucks, diesel power chain saws and other gasoline systems that would be used to get the wood to the neighbourhood utilities. Please also note that wood burning systems (because wood doesn’t burn as cleanly as gas) require frequent flush outs (i.e. running gas through the system to burn off wood waste) in order to continue running effectively. Combine this with the current price difference between electricity and gas and it will make it financially difficult to convince stratas and public entities to make the fuel switch that would create the quickest carbon reductions in buildings. The current price of residential electricity is currently around 9 cents kWh while the price of natural gas is only 3 cents a kWh. Should the city enforce a code which is merely GHG based without accounting for other factors, developers will simply switch from more efficient gas heating to less efficient electric heating while also passing off the additional operating costs to home buyers.

Please tune in next week for more detailed discussion of district energy systems as they apply to GHG reduction and the City of Vancouver's Zero Emissions Plan.

Office 365 Groups - How to Add Multiple Email Addresses And/Or Create Office 365 Groups for Secondary Domains

One of the great new collaboration features from Microsoft's productivity cloud offering is Office 365 Groups.  The new "groups" give you a bundle setup option for creating a collaboration space that includes:

• Group Inbox - communication and email in one space
• Group Calendar for scheduling group meetings and events
• Group Sharepoint Library for storing and working on group files and folders
• Group OneNote notebook for taking project and meeting notes
• Planning tool - For managing and assigning tasks

Normally these office 365 groups are created from Outlook, or from the admin portal of O365.  Although, as of this post, there is no way to create a group for a secondary domain... at least with a graphical interface.

So if you have primarycompany.com and you also have secondarycompany.com registered with your office 365 tenant, how do you create these amazing groups for secondarycompany.com?

Powershell of course!

Start by opening up powershell with admin permissions.  You will need your powershell to have your execution policy set to Remotesigned (or less secure).

Set-ExecutionPolicy RemoteSigned

Then you can use the below commands to connect to office 365's powershell session.

$user = get-credential

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $user -Authentication Basic -AllowRedirection

Import-PSSession $Session

Next setup your variables and create the group! 

$displayName = "desired group display name"

$members = @('member1','member2')

$owner = "owner name"

$primarySmtp = "primary@smtp.com"

$alias = "the alias you want"

$emailAddresses = @("email1@company.com","email2@company.com")

New-UnifiedGroup -DisplayName $displayName -Members $members -Owner $owner -PrimarySmtpAddress $primarySmtp -Alias 'Contact' -EmailAddresses $emailAddresses

That's it!  You can add more options if you like or you can run the above and then manage the group from the admin portal.

One day Microsoft will enable domain select from their GUI... one day..

Electric Vehicles Are Not Just The Future, They Are A Great Present

As LEED consultants, energy modelling professionals and sustainability consultants; we need to practice what we preach. Edge has been using a Nissan Leaf for the past 3 years and we’ve all come to love it. Here are our top 10 reasons for loving electric cars.

Charging at Hillcrest Community Centre

Reason 1: The City of Vancouver gives electric cars priority parking throughout Vancouver. There is Hillcrest Community Centre, Granville Island, and Vancouver Aquarium to name a few. These are great perks when the lots are full during busy time. They also give you free electricity

Reason 2: Electricity is cheaper than gas. In BC 1 kWh is roughly 8 cents. Gas is a 1.15 per litre or 12 cents per kWh. That means in an electric car its costs $3.48 to drive 100 miles. Some people even consider it a free car in comparison to the maintenance requirements of a gasoline engine.

Reason 3: As opposed to ‘filling up the tank’, charging our electric car is child’s play. While the city of Vancouver manages 78 charging ports, there are an estimated 175 other ports managed by shopping malls, hotels, parking garages etc. Apps like Chargehub and Plugshare can help you find the nearest charging station. In addition to the growing availability of charging ports throughout the city, charging at home is also a feasible option. Currently, 85% of electric car owners plug in over night at home. Most electric cars come with a charging cable (sometimes called a trickle charger), which plugs into the same outlet you’d use for your TV or vacuum.

Reason 4: Free charging around Vancouver. The majority of stations are free to use, all you have to do is sign up for the service or become a member. Simply swipe your member card, scan your phone app, or in some cases your credit card. The 3 most common charging providers in BC are ChargePoint, VERNetwork, and GreenLots.

Reason 5: BC’s electricity is 96% carbon free. Most of British Columbia’s electricity comes from Hydroelectric Dams (86%) with most of the remainder generated from Wind Farms, natural gas fueled thermal plants, and biomass power plants. BC Hydro offsets the remainder. This makes it a 100% carbon free car!

Reason 6: It can go well over its range of 135 km. We personally took our Leaf on a 170 km tour to Sechelt for a water audit. We were delightfully surprised that our Leaf was able to travel this distance from a full charge.

Reason 7: The Nissan Leaf has amazing torque and traction on icy roads. It has ABS, traction control, and Vehicle Dynamic Control. VDC is unique to Nissan vehicles. The system can help prevent under and over steering by reducing engine speed and applying the brakes individually on specific wheels. This means it can sense your wheels slipping on the road, and then engage to help you maintain control of your car. The Leaf is also on the heavier side, measuring at 3300 pounds. This is a great characteristic to have if you are worried about sliding out, as it has less body roll while turning and a more balanced center of gravity.

Reason 8: It charges as it goes downhill. Coasting and regenerative braking allow for the Leaf to charge itself. For example, if you got to the top of Mount Seymour with only one bar of charge left, on the way back down you could be back up to four and make it home with charge to spare.

Reason 9: No oil changes and almost no maintenance.  Electric cars have fewer moving parts than gas powered cars. This means less can go wrong. The majority of your time spent at the shop will be for battery inspections and software updates, which will happen about once a year. When you think of all the usual parts that need to be fixed/ replaced in gas powered vehicles such as spark plus, alternator, muffler, exhaust pipe, transmission, timing belt, you’ll be laughing all the way to the bank, and enjoying all the extra free time you will have.

The New Nissan E-NV200 Van

Reason 10: The Nissan Leaf will soon have a sibling, the E-NV200 Van. This will be a great addition as now a zero emission option will be available to taxi services, business, delivery, and much more. 

Our world is already starting to steer more toward electric vehicles, and in no time they will be the new normal. Every year their range gets longer and more charging stations appear in great locations. If you have range anxiety about long trips, the Chevy Volt, Tesla Model 3 and it’s rumoured the 2017 Leaf will have greatly extended ranges at an affordable price. Plus the BC government will give you cash back if you buy an affordable electric car. 

By switching to an electric vehicle, you could be saving 45 g/km-70 g/km of CO2 being emitting into the earth's atmosphere. There is really isn’t any need to wait to switch to electric vehicles. We’ve loved the last 3 years of driving one and will continue to follow and blog about our adventures with our Leaf. 

All smiles as we wait for charge at Hillcrest Community Centre

The Importance of Energy Modelling

In a recent article published by our energy expert Eoghan Hayes, he outlines how plug and lighting energy can have a major impact on building energy use.

In high-rise residential or multi-unit residential building, appliance plug and lighting energy account for 20%-25% of total energy use in the building. Eoghan explains that ‘the by-product of their electrical consumption of heat, which helps heat the suite in winter but becomes a hindrance during the summer, when we want to keep the suite cool.’  Over estimating in these energy modelling simulations can reduce heating energy and increase cooling, while underestimating them will do the opposite.

The article compared four different standards of energy modelling, analyzing the impact of underestimating and overestimating plug and lighting load power densities and schedules. ASHRAE 90.1-1-2007, LEED for Homes, Measured Utility Data, and BC Hydro New Construction Program Energy Modelling Guideline were used to compare the different methods and schedules used to simulate plug and lighting loads in residential buildings. While ASHRAE 90.1-2007 is the most common standard for lighting and plug standards, the LEED for Homes rating system is the most comprehensive for residential situations.

The LEED for Homes appliance calculator is used to calculate the annual energy usage per appliance. In the LEED rating system, points are rewarded for energy savings from appliance energy whereas most ratings systems do not. LEED for Homes requires Energy Star ratings for appliances. This usually accounts for upwards of 8% energy improvement from the baseline.

The results from all four standards ranged from 50.97 kWh/m2/year with Measured Utility Data to 56.16 kWh/m2/year with the BC Hydro guideline. The results indicate that 53.5 kWh/m/2year (+/-5%) would be an appropriate specification for lighting and plug power densities and schedules.

The article outlines how municipalities should state the appropriate energy density to ‘ensure consistency among energy models submitted for code and LEED compliance and prevent mistakes from submitted simulations’.

Water Use In Hospitals

Hospitals use a tremendous amount of water. In the U.S hospitals and other health care facilities account for 7% of water usage in commercial and institutional facilities. The EPA Energy Star Portfolio Manager has found that the median hospital uses 350 gallons of water per day per bed. But it doesn't have to be this way. With new incentives and technology emerging, water usage and waste is becoming easier to track and save. 

The Provincial Health Authority of BC commissioned Edge Consulting to conduct a water audit of the St Mary's Hospital in Sechlet, BC. The hospital felt that their water usage was too high and that there was room for improvement. Our report and audit found a number of places to save water as well as places where non-potable water could affordably and safely be used onsite. We also discovered decommissioned meters that were still being charged even though they were not connected to any water source. 

The report's biggest actionable item was the hospital's laundry area, which accounted for 47% of the total water use by the hospital. The amount of water was largely because the facility does healthcare laundry for most of the Sunshine Coast. In comparison, the American Water Works association estimates that laundry facilities in an average hospital only account for 9% of water usage. Edge is currently investigating a water treatment and capture design to use both storm water and grey water in the laundry room to reduce potable water use at the hospital by up to 47%. In addition, the hospital is looking into saving water usage by moving all machines to the most efficient water usage standards. There are often financial incentives such as tax rebates offered for making the switch to more energy and water efficient appliances such as Energy Star or Water Sense. Using these appliances also contributes to LEED for Healthcare points. 

The findings of the St Mary's Hospital water audit are an example of how important these audits are and how the Health Authority is taking a leadership position on water usage. As time goes on, appliances age, infrastructure becomes neglected, and new techniques and technology emerge that allow us to reevaluate water usage, upgrade, and save. Edge recommends water audits take place every few years to ensure that no water is going to waste, water bills are accurate, and new sustainable methods are being utilized to save you water and money.

Perception is Reality in Vancouver

In the eyes of most of the world, Vancouver is a hot bed of green building activity, sustainable living and green energy. In reality, it is a city without water meters, a robust compost plan, an enforced energy code, one that dumps partially or untreated sewage into it’s waters, and a myriad of other not so green practices.

 As a Sustainability Consultant, I’ve seen concerted efforts to showcase renewable energy projects in the urban environment. In places across Ontario, PV is often seen on buildings and the side of the road. In Minnesota I’ve seen urban wind projects in St Paul and Minneapolis. Both wind and PV have popped up on co-ops, animal shelters, homes and parks. In the Middle East, Abu Dhabi just finished the largest PV project in the world, and the Saudi’s are about to embark on their own renewable energy boom using the power of the sun.

 Even energy efficiency has become a requirement in the Middle East. In Saudi Arabia you now can not get an electrical connection until you have a certain amount of insulation. That’s something that is hard to hid or fake (unlike an ASHRAE “compliance” submission). They had no debates over which version of ASHRAE or other standards to adopt, (and then struggle to enforce) they simply are making people insulate their buildings. Contemplation of minimum requirements for equipment efficiency has also begun in earnest.

 While the Middle East isn’t known for green building, common construction practices will often get you all the LEED water credits. Cisterns, non-potable water usage, and onsite treatment is common at projects of all scales (even though water is heavily subsidized). Drip irrigation is the norm across the region and water conservation is a constant topic in design meetings. After all, when they first drilled wells in the 1930’s they were looking for water, not oil.

 In Vancouver you will be lucky to see renewable energy anywhere in the city. With the exception of a few city projects or start up companies, the low utility rates, lack of government incentive and perception that “we are green already” means you will be hard pressed to see renewable energy systems in the city. The cheap (basically amounts to almost free) water supplied to business’ and homes isn’t even worth sending you a separate bill for. In most cases it’s just tied to your property taxes and the city reads your analog meter once every 3 months.

 What you will see in Vancouver is glass condo after glass condo. This is despite the fact that the city has the highest energy standard in North America, and has had the highest energy standard for many decades now. You’ll also see lots of dead “green” walls. A fad that struck some years ago and would be something you would imagine would be easy to keep green in a rain forest like Vancouver. Usually these dead green walls are attached to buildings with an overall R value (insulation value) of about 1.5 (the energy standard is about 15 for reference).

 While Vancouver has one of the best urban plans in North American, and is blessed with relatively cheap and clean hydroelectric energy (thank you 1960’s provincial leaders), it really hasn’t moved past those two inherited elements in the few years it has decided it will be the greenest city in the world.

 It’s really time the City of Vancouver did some of the basics right rather than just continue to market on garbage cans that they want to be green by 2020. Start either enforcing your own building energy standard, or if you can’t figure out how to do that, just do what the Saudis did and just require insulation (a novel concept in Vancouver I’m afraid). Start metering and charging for water. Abottsford and Calgary have water meters and Vancouver doesn’t. How can these pick up truck towns be more water conscience than one wanting to be the greenest in the world?

 While perception often becomes reality (as it has in the case of Vancouver’s green claims), there needs to be more to Vancouver’s efforts than what City hall buys and what cars their fleet uses. Pretty much every city out there is working in that direction. “Greenest” certainly requires much more strategic and real effort than what is being expended to date.
