Green Energy Policy Failures and Real Sustainability

The one thing that is missing in the whole sustainability area and renewable energy policy is a sound focus on the economics and the finance of green energy. With new buildings this is not a problem, but the greater market is retrofits in older buildings and in that arena by and large people are wasting their money with tinkering in the margin instead of making the most of the opportunity.

If it takes 10 years for a new efficiency standard to work its way through the car fleet, then the picture is much worse with buildings, because they typically last a bit longer than cars. Living in one of the older parts of NYC, I'm surrounded by 50+ year old structures, which still have plenty of life left in them.

Policy Failure #1:
Conflating Energy Efficiency and Renewable Energy

Conflating energy efficiency and renewable energy is an obfuscation which serves only the fossil fuel industry, which is why they eagerly embrace "energy efficiency." This is how they compete against renewable alternatives. Energy efficiency is a marketing strategy and a greenwash of the fossil fuel industry, and it is financially disruptive. In various posts on this website, I have demonstrated how this manifests itself across many programs, and acts as a way to divert investment from green technology, even if it would be financially more advantageous to property owners.

Since this approach benefits the fossil fuel industry, this is a typical policy failure, which achieves the opposite of what is intended, and change is in order.

Policy Failure #2:
Arguing over Clean Fuels is like rearranging the deck chairs on the Titanic

As argued in earlier posts, the whole NYC Clean Heat program is a massive example of policy failure in this area. The whole point is we are in a transition away from fossil fuels, and towards renewable energy, and now that we generally realize how much energy is consumed by buildings, and green energy technologies that are suited for mounting on buildings are proliferating, it is time for policy makers to encourage this development, instead of putting road blocks in the way. Even with all of the best intentions, this is how most programs have worked out so far.

Policy Failure #3:
Not seeing the forest for the trees - misguided incentives

Tremendous amounts of time, effort and money are wasted over what technologies are blessed with the Investment Tax Credit, which is good for sales for the companies that make them. However this puts the focus on individual technologies, and not on the whole project, which can only be judged on the property as a whole. If accountants start specifying the wrong components because of ITC, inferior projects will be developed, never mind how good the individual components are. There is a right place for everything. But having accountants make engineering decisions is counter-productive.

Policy Failure #4:
Disregard for long-term financial planning is encouraged by incentive programs

By various forms of incentives on equipment, such as the ITC, or a requirement to specify Energy Star equipment, regardless if it is the best for the job from an engineering standpoint,  suboptimal projects are being developed. What matters is to reduce the Green House Gas emissions on a building level, so the incentives should address the achievements of the building as a whole. Energy Star is fine for a fridge or a micro wave, which are one-off decisions, but specifying the credits on construction components causes accountants to  mess up the best engineering. More importantly the whole industry has gotten in the bad habit of evaluating financial decisions at the component level, based on payoff of that component in terms of savings, which gets in the way of long-term capital plans, which would reveal very different design strategies.

Policy Failure #5:
Absence of simple objectives, such as reducing Green House Gas emissions

Once the policy focuses on the right issues, namely reducing Green House Gas emissions building by building, better designs will proliferate, and long-term capital budgeting becomes the obvious way to design capital plans. Thirty year cash flow models should be the norm, and ideally should be required by financiers and e.g. PACE bonds. The whole point of PACE bonds was to have a way to raise the upfront capital needed for this transition, which would add to long-term asset values. Instead, a lot of PACE money is being wasted on dubious "energy efficiency" projects, and property owners are frittering away the long-term appreciation of their buildings by investing in renewable infrastructure, and moving energy from the liabilities to assets.

Conclusion:
How to Achieve Sustainability in Spite of Policy Failure

In spite of all policy failures, building owners have a vested interest in sustainability, because it increase asset values, and they should be using 30 year capital budgets for energy retrofits with green energy technology; in other words the various programs and incentives should be ignored and the long-term economics of the building should get priority, before you figure out how to qualify for the incentives.

NYC Clean Heat Destroys Property Values

PlaNYC Heating Oil Regulations are pushing buildings from #6 and #4 oil to #2 oil, natural gas, or biodiesel. Conversions are in full swing. Sadly, many of the buildings are suitable for renewable energy conversions which would produce far better results for the environment and for occupants, as well as better long-term financial results for owners. It says on the website that owners can apply for compliance waivers through NYC DEP. Owners should do this if their buildings are suitable and if they have the financial wherewithal to make that transition to a renewable solution. As long as a credible renewable solution can be found, owners are in fact placing a long-term hedge on their energy costs, and will do far better than they would going along with the conversions which the City is pushing. The typical 30% gains in efficiency are too easily wiped out by the next energy price hike.

Compound investment returns from energy independence through renewables

Not only are these conversions counterproductive as long as there is a renewable energy alternative, owners are being offered subsidized financing to make it easier to make the wrong decision, and destroy the asset value of their buildings. Having said that, there may be some buildings that realistically could not make a transition to renewable energy economically, but in many cases it is well within reach to do in buildings that are 40 units and up. (Size matters because of economies of scale). In the long run, this will produce a steady path to asset appreciation.

Presently we are in PlaNYC 2013, but it started in 2007 as Plan NYC 2030, and since then evolved to PlaNYC 2.0. Clearly this is an extraordinarily important plan, and it puts NYC in a very proactive stance with respect to climate change issues, but in this area of renewable energy, not nearly enough is being done. Most of that shortfall rests on the general confusion in our society that energy efficiency somehow is an additive phenomenon and would result in energy independence. In that context renewable energy is then relegated to a marginal role. If you were to actually do a long-term energy plan for a building, you would see this is not so, unless the building is not capable of a renewable conversion. Most of the buildings that burn #6 could do it.

The first issue is a choice of what energy system do I want? Do I make my energy (renewables) or buy my energy (subscription-based, gas, electric, oil). The two paths are to a large degree mutually exclusive, because of engineering interdependencies. One clear example, if I can go the renewable route and perhaps eventually eliminate gas for cooking, and most heating/cooling, I may be able to eventually do centralized HVAC, and choose very different replacement windows, etc.

Most importantly, the path to energy efficiency of my existing fossil fuel system is an investment in becoming a long-term consumer of gas or oil, or even biodiesel, so it is a customer retention program for the energy industry. In this case it is driven by the well intended reduction of CO2 and particulates emissions of gas versus oil, but as long as a renewable alternative exists, the latter would produce greater benefits in the long run. Successive investments in energy efficiency produce strongly diminishing returns, so a property owner paints himself into a corner financially. Once the transition to a renewable infrastructure can be made, the financial future of that building is assured, because subsequent investments will produce compounding results. The transition to renewable energy practically ensures building preservation, because of superior economic performance over time.

Underwriters risk collateral values by underwriting energy efficiency

If you check the website for NYC's Clean Heat program you will see energy efficiency as the sole qualification for subsidized financing. All the usual culprits are there, CPC, NYSERDA et al, many of whom have energy credentials, for this conversion effort is a subsidy to the energy industry to the detriment of building values. Underwriters should learn to test for the difference between energy independence (renewables) vs. energy efficiency of carbon-based energy systems, simply because of the issue of diminishing returns with the former, and compounding returns with the latter. Energy Efficiency loans are riskier than Energy Independence loans, by far. To lump them all into one category is bad for owners and bad for underwriters. Building values for buildings that are 50% or better energy independent would rise strongly over the life of the mortgage, compared to buildings that invested in energy efficiency alone.

DaBx PlaNYC 2020: the Energy independence plan

Windspeeds over NYC are higher than Chicago

With my consulting company DaBx Demand Side Solutions, we offered an alternative model to Mayor Bloomberg on July 4th 2011, which would achieve better results, and faster than the mere conversion from #6 to natural gas, and, as noted above, better financial outcomes for building owners. The plan is within reach for probably at least 50% of the building stock that is now converting to natural gas. It is more capital-intensive at first, but not much so once you evaluate it against the alternative of the forced gas conversion. The outcomes for air quality and building preservation would be far superior, not to mention public safety and national security. The conversion to gas only seems easier and cheaper in the short run, it is not if you do a 30 year energy plan for a building.

The basic model is based on understanding that in C and D class apartment buildings that are usually only 6 stories high, the old steam boilers usually provide Domestic Hot Water (DHW) through a coil in the boiler, and 30-50% of BTU output of those boilers goes to DHW. In those cases, economically feasible solutions can start from providing DHW with renewable energy, either geothermal or solar thermal. This eliminates 25-50% of CO2 and particulates emissions right away, it also gives the boilers the summer off, so it extends their useful life, and then at the time when the boiler dies from natural causes, the conversion to renewable HVAC can be completed. And yes, the famous split incentive between landlords and tenants needs to be cured.

Energy independence, wind and geothermal energy

Energy independence of buildings means the building stays lit during an outage, even if only partially. The two technologies that have been underappreciated so far are geothermal and wind power. In 2008 the press practically ridiculed Mayor Bloomberg about his advocacy for wind power on buildings, but they did not understand that specific wind turbines for buildings where just starting to come to market, and the Mayor was right on target, perhaps without knowing it. Average wind speeds around NYC are higher than in Chicago, supposedly the windy city. Moreover, around buildings, wind speeds pick up dramatically, offering excellent opportunities for wind power especially in the city.

Geothermal is the most strategic technology of them all, and City Hall is only just now starting to research it. Basically a geothermal system gives you a 400% gain in BTUs, and most importantly it can act as energy storage, besides providing domestic hot water. Here is one place where compounding returns come in, for energy storage is the single biggest problem in renewable energy, but DHW ends up acting as energy storage for your building. Unfortunately most existing geothermal systems in apartment buildings were wrongly designed, as DHW only, and not for energy harvesting. Buildings need 30 year energy plans, not point solutions.

Conclusion:

PlaNYC can be much more successful if the confusion between energy efficiency and energy independence through renewables is eliminated. Better outcomes for building preservation, air quality, and economic competitiveness of the city would result. Energy efficiency of a building with a carbon-based energy system is financially inferior and prolongs the period of CO2 emissions, energy independence through renewables reduces CO2 faster.

Off the grid in four easy lessons #4

Off the grid is a direction not a destination, and the principal instruments to get there are financial analysis and economic modeling, not technology. So never mind the government has no energy policy, just a rag-tag group of programs and incentives that tend to confuse people more than help towards a solution. Never mind that utilities and oil companies do everything they can to seduce real estate owners to remain happy carbon customers till the cows come home with all kinds of energy efficiency solutions. It is up to the property owner to make sense of them, and the principal tool you have is the Capital Asset Pricing Model, aka CAPM and once you start studying it, and looking into the various technology options you may have regardless of what your starting point is, you will be amazed. Research CAPM, study Internet resources, including CAPM Free Questions.

Energy Efficiency and equipment payback - the trap to be avoided

To recap from earlier posts: energy companies (utilities, oil companies, etc.), and vendors of equipment will inevitably try to get the attention of real estate owners with investments in  energy efficiency, which are to the benefits of their shareholders, and NOT of the real estate owners. The nature of energy efficiency is that the first investment always looks very good, and typically offers outsize returns (on the basis of payback), and 99.99999% of owners do not stop to think that they are committing to an investment path that perpetuates their indentured servitude to carbon energy. The vendors capitalize on these insights by selling their "solutions" based on marginal analysis of energy savings, always showing a wonderful payback for their equipment, and waiving around Energy Star labels, tax incentives, or other subsidies. If they are successful, you've invested your money in remaining the customer of your energy company forever. This is voluntary vendor lock-in. Various tax incentives, but also NYSERDA, Energy Star, CPC, PACE, and most mortgage providers will steer you wrong because their programs are useful only if your own CAPM analysis says so. Don't run your financial future based on someone else's say so.

The morning after effect comes in when you want to do the next "investment," which is worse but you'll probably still do it. Some day you'll have to realize that diminishing returns mandate that you'll never ever find another investment as good as the first one. The cynic might say these are not investments at all, but operational savings. Even various form of PPAs offered by energy companies tend to suffer the same analytical defects and will benefit the shareholders of the energy companies more than the home owner. Caveat Emptor!

Off the Grid with CAPM

Getting Off the Grid starts with the one and only thing that every property owner should do first, last and in between: make a 30 year financial model of your property, and use it to model your own strategic energy plan, always comparing the base case as the investment in energy efficiency based on the existing infrastructure, with the alternative case using green energy. Again, energy efficiency will never get you off the grid, green energy will, if you figure out the right way of implementation. The first decision is a make or buy decision about energy: should you buy it on a subscription basis, or generate your own. Watch values of net zero properties for reference.

It is never ever what the salesmen will tell you, nor should you let yourself be confused by tax incentives, NYSERDA programs, PACE and/or other energy efficiency finance. They will all steer you wrong, to the detriment of the long-term value of your asset, your property. Study the energy economics of your property first, before you figure out what incentive programs are to your long-term advantage. You will repeatedly find that financing mandates, e.g. of Energy Star equipment, may benefit the energy industry more than it benefits you. Don't buy it unless it actually helps improve the long-term value of your property. Financial sanity starts with CAPM!

OFF the Grid: The basic assumptions about the relevant cash flows

Here is a list of the major cash flows and assumptions you need to document:

1. For starting asset value use Zillow, or a similar service.
2. Identify ALL forms of energy you use - it may be two or three.
3. Make a 12 month model so you start to see seasonality, you will therefore have 360 cash flow periods.
4. Track both consumption and pricing.
5. Notice that in deregulated states it probably makes sense to split the cost of delivery and supply. In many cases, certainly in NYC, delivery is 65% of your utility cost per kWh or per Therm, and rising inexorably ABOVE the rate of inflation. For my gas it is 95%, because I use so little of it.
6. Identify specific inflation rates for all your energy component costs and rates.
7. Track reasonable assumptions for maintenance (i.e. annual costs, but also periodic replacements, such as a boiler or water heater that may last 10 or 15 years).
8. Make a base case (A) based on your existing energy mix, with incremental investments in energy efficiency. You will start to see how these investments will get wiped out by ongoing price hikes, let alone spikes such as have happened from time to time.
9. Make a case B based on renewable energy. Try to identify the rationale for a strategy to eliminate one fuel completely (oil or gas), or as near as you can get to it.

Experiment with such a model until you are comfortable. Until you are, you are not ready to begin shopping for energy solutions.

Off the Grid: Sane assumptions for getting there

As much as possible try to think of projects to coincide with maintenance things you'd have to do anyway. In other words, if in five years you would have to replace your boiler, that may be the timing for switching to geothermal, or solar thermal, or some other combination, and you may only need a very small boiler for backup. Or, if your roof needs to be replaced that may be a time to improve on insulation, and/or solar or wind installations. You do not want to install a set of solar collectors with a 20-30 year life expectancy on a roof that only has 5 years of life left in it.

Avoid tankless water heaters like the plague. Domestic Hot Water storage is a very efficient energy store, you may need it in your design later on.

CAPM: valuation issues

Study the energy independence profile of homes in your area. With net zero homes and buildings growing, energy costs will increasingly become important in valuation. If a few homes in an area are energy independent or close to net zero, that will start to diminish the values of all other properties.

Be prepared to learn a lot. Both good and bad. The renewable energy path is more capital-intensive, but it will increase your property value more. You will find opportunities with compound returns because of synergies. Keep studying what is going on in your market, and never ever listen to a sales rep coming with payback periods, and various incentives. He or she is stealing the value of your home.
