Green building is smart building. Not taking the conventional route does add an extra expense, but payback is short . A lot shorter than most people think. And once built, a green building delivers a lifetime of energy savings.

To make the buildings energy efficient there are many market- barriers

1. High Cost: Builders and landlords (and homeowners) can recoup investments in energy efficiency by charging more in rent or by seeking a higher sales price. But in practice, it is difficult to document the value of energy-efficient investments in order to command those higher prices.

2. Lack of knowledge and experts: Information can simultaneously benefit an unlimited number of people, and once it has been supplied, anyone can freely disseminate it to whomever they wish. The manufacturers and early adopters who generate it may realize little private benefit.

3. Low demand in market:

4.Unaffordable for small businesses: Consumers who invest in energy efficiency require higher rates of return when the investments are illiquid and they are unable to diversify away the risk.

Environmental Impact:

Using the five core areas common to comprehensive green building rating systems as a guideline, the following benefits can be observed by building green:

Site

reduced sprawl
preservation of natural spaces, wildlife habitat and native species
minimized reliance on cars from improved access to infrastructure
reduced soil erosion from sustainable landscaping
minimized light pollution from reduced and optimized lighting

Water

reduced water consumption
water reuse and collection

Energy and atmosphere

reduced greenhouse gas emissions
reduced energy consumption

Materials and resources

waste reduction
locally sourced materials and resources
minimized material usage due to durability
renewable resources
natural materials

ROLE OF ENVIRONMENTAL MINISTER: Sandeep Kaur representing the role of environmental minister. Here are important points to be considered as Environmental Minister.

Policy Standards: Policies, such as appliance standards, that require consumers to invest according to lower discount rates, reduce consumers' overall economic wellbeing. Two market failures that illuminate the need for government support of conservation policies are the external costs of energy consumption and production and the lack of aggregate insurance against energy-related risks.

The key steps: Process Efficiency, waste disposal, infrastructure, product design, packaging and transport.

Environmentally Sustainable Design (ESD) Principles There are two levels of compliance when it comes to ESD principles – mandatory and best practice. Page 6 of 7 Mandatory Requirements Construction Waste – to the satisfaction of the relevant local authority. Operational Waste – to the satisfaction of the relevant local authority. Council’s Best Practice Standard Building design should incorporate features that take into account a building’s whole life cycle: • Adopt a recycling target of at least 70% for all demolition and construction waste (by mass). • In addition, adequate facilities must be provided to ensure waste separation and possible on-site reuse is facilitated during the building’s operation.

An ENERGY STAR three-bedroom single-detached home in an average Saskatoon community with a typical 1,200 square foot payback estimate is shown below in comparison to a regular three-bedroom single-detached home in the same location. Despite the wide range of construction prices per square foot, an estimate of $125 per square foot is chosen for this example. Average construction costs

(Standard home) = $125/sq. Ft x 1200 sq. ft. = $150,000

Average construction costs (green home) = $127.50/sq. ft. (2% premium ) x 1200 sq. ft. = $153,000

Bottom of Form

Annual energy costs = $250/month x 12 = $3000

Annual energy savings = $3000 x 0.25 (25% energy savings) = $750

Interest = $3000 x 0.04 (4% 3-year fixed mortgage) = $120 x 3 years (payback period) = $360

Cost differential = $3000 + $360 – $1000 (government rebate for purchase of an ENERGY STAR new home) = $2360

Payback period = $2360 (cost differential) / $750 (annual power savings) = 3.1 years* (without the government rebate, 4.5 years)

* Energy utility rates have been increasing at about the rate of inflation. Any changes to the rate of utilities will affect this payback period. ROI on the $3000 also needs to be accounted for. The average Government of Canada bond rate is about 1 to 1.5% per year.

Additional rebates available in Saskatchewan for purchasing an ENERGY STAR home, according to Resource Efficient Housing Inc., include:

$1,000 rebate for the purchase and installation of a solar domestic hot water heating system that is certified to the CAN/CSA F379 standard and provides a minimum energy contribution of 6 GJ/yr.
$3,500 for the installation of a CAN/CSA-C448 compliant Geothermal System.
$150 for the installation of a drain water heat recovery system, and/or
$100 for the installation of one qualifying natural gas appliance or $250 for two qualifying natural gas appliances. Qualifying natural gas appliances include clothes dryers, barbecues, cooktops, and ranges.
10% mortgage loan insurance premium from CMHC

After the 3.1 years are up the extra cost of building green is accounted for and you’re living in an energy efficient home that will continue to save you (and future homeowners) an average of 25% per year.

Emissions of greenhouse gases in British Columbia

In 2017, the province of British Columbia produced a total of 62.1 megatons (MT) of carbon dioxide equivalent (CO2e) emissions. Since 1990, greenhouse gas emissions have increased by 20%.

Compared to the national average of 19.6 tonnes of CO2e, the emissions per person in British Columbia are 36% lower at 11.6 tonnes of CO2. As a result, the province has one of the lowest carbon dioxide emissions in Canada.

In British Columbia, transportation accounts for 37% of total emissions, followed by oil and natural gas at 22% and heavy industry (which includes smelting, cement production, and chemical production) at 14%.

Figure 1: GHG Emissions by Sector in British Columbia

Oil and gas industry segment. In 2017, the province of British Columbia produced GHG emissions equal to 13.4 million metric tonnes of carbon dioxide (MT CO2e). These two facilities made and sent out 12.7 million metric tonnes (MT) each. The natural gas distribution facility (MT) made and sent out 0.8 million MT.

Almost all of the power generated in British Columbia originates from renewable sources. Some 0.2 million tonnes of carbon dioxide equivalent (MT CO2e) were emitted from British Columbia's power sector last year, which is about 0.2 percent of all of Canada's GHG emissions from electricity generation.

Saskatchewan's GHG emissions

In 2017, the province of Saskatchewan produced 77.9 MT of CO2 equivalent emissions. (CO2e) emissions from Saskatchewan have increased by 75% since 1990, according to government data.

Canada as a whole emits 67.7 tonnes of CO2e per capita, which is 246% more than the national average of 19.6 tonnes.

Energy-intensive industries like oil and gas production account for 33% of Saskatchewan's emissions, with agriculture accounting for 23% and power generation accounting for 20%.

Figure 2: GHG Emissions by Sector in Saskatchewan

In 2017, greenhouse gas emissions from the oil and gas sector in Saskatchewan were 25.3 million tonnes of CO2 equivalent (MT CO2e). 23.7 MT came from production, processing, and transmission; the rest came from petroleum refining and natural gas distribution together, which made up 1.6 MT.

Saskatchewan's energy industry ranks second only to Alberta's in terms of greenhouse gas emissions, owing primarily to the province's heavy reliance on coal-fired electricity generation. This is how it worked: Saskatchewan's 15.5 million metric tonnes of carbon dioxide emissions in 2017 were a small part of Canada's total greenhouse gas emissions from power

Conclusion: Saving energy now reduces the need to construct additional generating capacity in the future. This practice will reduce long-term energy production costs and the social and environmental impacts associated with some new generating projects.

I liked the attempt to do a costing. Not clear what specific policy you are recommending. BC already has a very aggressive building code for new houses that will require net zero by 2030. Maybe you should focus on codes that would require upgrades to existing buildings. Will resend you info on this idea
