Building owners and property managers that take on the responsibility of limiting energy consumption can be looked at as environmental leaders. While energy management adds extra tasks to everyday lists, the benefits outweigh the time and money spent, which is usually returned in savings.

There are numerous areas to take into consideration when it comes to commercial buildings, and being that commercial buildings are generally large, the impact can be large as well. These areas include the HVAC system, chillers, windows, lighting, electrical equipment, and any other factors that may be contributing to the building’s energy consumption.

While there are various ways to be involved with bettering the environment outside of where you live and work, starting in a place that you occupy everyday has the potential of having long term results if the actions are carried through as often as you’re there.

Consider creating an outlined approach for managing the building’s energy with these areas in mind:

Identify Sustainable Alternatives Where Energy is Being Used:

  • Are there upgraded, energy-efficient versions of the equipment you can be using instead?
  • Could you use different settings on the equipment?

Assess the Purpose of Every Area:

  • Is the lighting being utilized in every room?
  • Is the size of the HVAC system an adequate fit for the building and its purpose?

Evaluate Maintenance Plans:

  • How frequent are the utilities maintained?
  • Do the maintenance technicians practice with energy efficiency in mind?

Look for Possible Areas of Energy Loss:

  • Are the building’s windows sealed properly?
  • Is the equipment too old for efficient functioning?

These are questions you should ask yourself if you’re trying to assess energy consumption and find that alternative route to save not only energy, but money as well.

After addressing these questions, you may find yourself planning to make some changes. Here is the information you should know for doing so:

Energy Efficient Equipment: Whether it’s the HVAC system, the utility lighting or the other various appliances being used in the building, there are energy-efficient options to consider. This includes ones with ENERGY STAR ratings, which match the standards set by the government.

Settings & Thermostats: Just by being knowledgeable about specific settings and the different types of available thermostats, you can be saving a substantial amount of energy. Depending on the type of building and the function(s) of the building, settings can be applied to use less energy in an area that doesn’t need it. The same idea goes for thermostats. Programmable thermostats allow for precise regulation of energy consumption. This means making sure the temperatures aren’t set too high or too low when the building or part of a building isn’t in use. Programmable thermostats keep the location comfortable when needed, but help save energy when it’s not.

Lighting: It’s better to be the building that turns its lights off when it isn’t being used, than a building that keeps them on 24/7. It’s also important to consider energy-saving types, such as LED or solar. With these kinds, you can also invest in timers and dimmers.

HVAC Size: According to ENERGY STAR, “at least 25% of all rooftop HVAC units are oversized, resulting in increased energy costs and equipment wear.” Determining what size HVAC system the building needs is a job for a professional technician, and it’s an important part of the overall building assessment.

Maintenance: Building maintenance is not only important for saving energy and money, it’s important for the building’s health and those occupying it. This includes electrical, HVAC, plumbing, etc. While there are tasks you can manage on your own, there are specific tasks that are recommended for the hands of a professional technician. Whatever the area, it’s important to have maintenance scheduled. Having a definite schedule helps to prevent sudden issues, which prevents sudden energy loss as well.

Technicians: Certain companies know the importance of offering energy-efficient services. This means that they practice in ways that are beneficial for the environment. Research the companies in your area and look for the ways they’re working to save energy and you money. This is an important quality, and more companies are beginning to realize that.

Windows, Replacements & Other Areas of Loss: Other ways to assess energy is by looking into the not so obvious. This includes windows, old systems that don’t show signs of stress until it’s too late, and too many running appliances and pieces of equipment causing heat. If windows aren’t sealed properly, especially in summer and winter, your HVAC system may be working harder than it has to in order to reach the desired temperature. Leaks of hot or cold air will cause this. Another concern are systems that don’t show signs of stress. If the system is old, it’s definitely recommended to have it maintained, even if you think otherwise. The inside has moving parts that may be working very hard to keep it running, and the machine giving out might be the first sign if you wait too long. Lastly, there may be too much heat. Too many heat producing appliances or pieces of equipment may cause the air conditioner to work harder, similar to an open window on a hot summer day.

Commercial buildings don’t function alone, they need the help of energy, and all building owners and property managers can help conserve it.

If the benefits of a sustainable retrofit are so robust, why isn’t everyone doing one?

PJ PicturePaul L. Jones, CPA, LEED Green Associate, Principle, Emerald Skyline Corporation

A sustainable retrofit includes replacements and upgrades that result in lower energy, operating and maintenance costs as well as improved occupant satisfaction. A sustainable facility will have a small carbon footprint, limited environmental impact and conserves natural resources. They can range from replacing conventional lights to LED bulbs, adding motion-control switches and installing low-flow water fixtures to installing a green roof, replacing the building skin and adding solar panels to all of the above.

When you fully understand the economic benefits of doing a sustainable retrofit which include lower expenses and rent and occupancy premiums resulting in higher NOI as well as reduced cap rates resulting in higher long-term values, you realize how few property owners, managers and tenants have actually made the decision to pursue an upgrade of their building(s), it initially does not compute a United Nations Environmental Program Finance Initiative Investor Briefing entitled “Unlocking the energy efficiency retrofit investment opportunity” reports:

  • Buildings with the Energy Star label had significantly stronger performance than similar unlabeled buildings: 13.5% higher market values, 10% lower utility costs, 5.9% higher Net Operating Income (NOI) per square foot, 4.8% higher rents and 1% higher occupancy rates.
  • A study using Co-star data concluded that LEED-certified buildings and Energy Star rated buildings versus non-rated buildings had 8% higher effective rents (a function of both the rental amount and the occupancy rate) and a 13% sales price premium.

See also my article, “Welcome to Sustainable Benefits – Let’s begin with the benefits of doing a commercial building sustainable retrofit” for additional survey results and case studies that demonstrate the results building owners and managers have realized.

In a 2012 study by The Rockefeller Group and Deutsche Bank Climate Change Advisors, however, reported that approximately $72 billion in capital is needed to be invested in sustainable retrofits to effect profitable energy efficiency in the existing building stock. However, the total spent in 2012 was just $1.5 billion.

Once you understand the relative perspective of the stakeholders in both the investment and the benefits, the resistance to effecting a sustainable retrofit can be understood.   Let’s dissect the framework in which the decision to make sustainable improvements are made and the issues and motivations that cause a property owner not to update and improve their property which are:

  • Short-term investment horizon
  • Incongruous lease structure
  • Capital and operating budget limitations
  • Financing availability, complexity and/or cost
  • Limited knowledge, time and/or motivation to effect energy upgrades

Understanding these investment, operational and financial constraints is the first step in developing solutions that will result in making the sustainability and resiliency of the existing stock of commercial buildings feasible and practical.

Short term investment horizon:

In the era of REITs, CMBS, hedge funds, crowdfunding and private equity, investment hold periods are frequently in the 3 – 7 year range when investors can typically optimize the IRR and other profitability measures or bail on a bad investment and reallocate their capital. As a result, many investors will only consider sustainability measures that have a two-to-three year payback period. Deep energy retrofits with savings of 30% to 50% that result from retrofitting multiple building systems requiring more time and capital to effect are tabled and not done.

Solution: The current and prospective investment environment will continue to reflect hold periods that are relatively short; however, the solution is for investors, owners and managers to realize that a sustainable retrofit enhances the long-term value of the property and will cause investment returns to increase. Including the costs and benefits of upgrading a building is a common way for sponsors to demonstrate the inherent value of a property – especially one that is not fully leased or suffers from functional obsolescence or poor aesthetics and other physical limitations on its marketability to prospective tenants. Many business plans include upgrading a building from one class to a higher class which results in increased rents and lower cap rates. As evidenced by many studies, including sustainability and resilience in the business plan is an increasingly important component in any market-oriented building upgrade. The solution is for sponsors, investors and owners to realize this and to put it into practice.

Future articles will present sustainable ideas many of which can be implemented with no capital investment required.

Incongruous Lease structure

Commercial buildings, a/k/a income properties, are leased to tenants pursuant to a variety of lease structures with the four most common being as follows:

  1. Gross Lease, or full service gross, is a lease where the landlord/owner collects a stipulated rent amount and is pays all expenses including real estate taxes, insurance and operating expenses that are comprised of utilities, repairs and maintenance and management. The room rate paid for a night in a hotel and a lease for a self-storage unit are examples of gross leases.
    • Apartment leases are typically considered to be a gross lease as the landlord is usually responsible for all operating expenses including real estate taxes, building insurance, common area maintenance and utilities, and property management while the tenant is responsible for the unit’s electricity (and sometimes water) and interior maintenance.
  2. Modified Gross Lease is a gross lease where the landlord/owner collects a stipulated rent amount plus a reimbursement of real estate taxes, insurance and operating expenses which exceed an agreed upon amount which is typically an estimate of the building expenses for the initial lease or calendar year. Typically, at the end of the year, the actual expenses are reconciled to the estimate and any increase is passed to the tenant based on its pro-rata share. Most multi-tenanted office buildings are leased pursuant to modified gross leases.
  3. Net Lease is a lease where the landlord/owner collects a stipulated rent amount plus building expenses which include real estate taxes (net), taxes and insurance (double net); or taxes, insurance and operating expense (triple net) depending on the terms of the lease. If the building is multi-tenanted, the tenant pays its pro rata share.   Most net leases are currently triple net. Retail properties are typically leased using a triple net lease.

In a standard Full Service lease, there is no split incentive in the lease structure as any and all savings realized from a sustainable retrofit inure to the benefit of the owner; however, the property manager may not be incentivized to promote a retrofit as it would be responsible for supervising and effecting the improvements without any additional management fees. With regard to an apartment complex, the landlord’s incentive to invest in energy efficiency measures is limited to the common areas – or to improve the competitive position and marketability of the units to prospective tenants.

In a standard Modified Gross lease as well as a Net lease, the landlord/building owner is not incentivized to invest the time, money and personnel resources to effect a sustainable retrofit as the landlord receives no direct financial benefit as the tenant pays the operating expenses and receives all of the benefit of lower operating costs.

Solution: Creating a lease structure that equitably aligns the costs and benefits of efficiency, sustainability and/or resiliency between building owners and managers, known as a green lease, aligned lease, high performance lease or energy efficient lease, will create sustainable and substantial benefits, both quantitative and qualitative, for both tenants and owners/landlords.

  • According to Jones Lang LaSalle, “A green lease need not be complicated. Often it merely requires structuring terms and agreements already in place, such as temperature settings and building operating hours, in a fashion that provides sustainable cost savings with negatively impacting building performance.”

To effect a green leasing program that includes both current and prospective tenants, engaging a consultant that understands both commercial lease structures and efficiency and sustainability retrofits to maximize the sustainable benefits to be derived therefrom.

Green leases will be addressed in detail in a future article.

Capital and operating budget limitations

Many properties suffer from a breakdown in communication and financial planning between building managers and building owners.   Building managers typically operate a facility pursuant to a one-year budget which causes them to budget and implement projects with a short term (1- 2 years) payback period. Consequently, capital improvements that have a longer payback period are not often recommended by management, or if recommended, not implemented by ownership due to a combination of knowledge, time or motivation to consider an energy upgrade or a perceived lack of available capital. This short-term horizon again limits the nature and extent of any efficiency or sustainable upgrades and prevents ownership from reaping all of the economic benefits that inure from a building retrofit.

Further, many times neither building ownership nor building management understand the nature and availability of financing options, tax credits, utility and local government rebate programs. Some of the programs, or a combination of programs, can result in building owners not having to come out of pocket to fund the improvements; however, the unique nature of them requires time which is typically focused on achieving the primary business goals of the organization.

Solution: Engage a sustainability consultant with knowledge of property operations and management as well as the nature of the available financing, credits and rebates – and how to source and evaluate alternatives in order to minimize actual investment dollars and the cost of any financing incurred.  Conducting a life-cycle analysis in addition to other financial analyses will provide ownership with the information needed to make the business decision.

Future posts will present investment analysis tools and methodologies with examples of the real economics of sustainable retrofits.

Financing availability, complexity and/or cost

Contrary to popular belief, energy efficiency and sustainability retrofits benefit from a variety of financing alternatives. However, for real property professionals who work with mortgage loans, mezzanine loans, preferred equity and similar forms of financing, retrofit financing options ranging from equipment leases to ESCO (Energy Service Company) contracts and PACE (Property Assessed Clean Energy) liens is a whole new world. When you add in the variety of tax credits, utility rebates and vendor financing, the options become complex.

Further, the sources for financing a retrofit are not usually the same ones that provide mortgage financing so it is a new arena which makes accessing sources and evaluating options time consuming and prohibitive.

Solution: Engaging a professional who is familiar with the types and sources of retrofit financing as well as the typical structures and issues of which owners should be aware is the easiest and most efficient way to determine and evaluate the options based on the financial and non-financial objectives of the owner.

The various retrofit financing options, examples of tax credits and utility and municipal rebates will be described and explained in future posts.

Limited knowledge, time and/or motivation to effect energy upgrades

In today’s competitive commercial real estate environment that is still recovering from the devastatingly harsh Great Recession of 2007, keeping your focus on the primary business of keeping space leased (as hoteliers say – heads in the beds) and watching every penny to the bottom-line is the first priority of owners and managers.

Even though the results of an efficiency, sustainability and/or resiliency retrofit provide a substantial boost to the net operating income (and cash flow) of a property, it does not become a high priority item due to lack of understanding of the process, the capital, management and labor requirements, the extent of the potential disruption to operations and tenants as well as knowledge of the additional value (rent premiums, occupancy premiums, higher quality tenancy, lower cap rate, increased investment value) and business benefits (reputation, image, goodwill) to be derived therefrom.

Also, many times building management staff, who may have the understanding of the sustainability technology will not have the financial literacy to present a compelling case to ownership.

Further, many energy service providers (who are typically considered to be the expert in facilitating a retrofit) do not know or understand the financing options that are available to building owners. Accordingly, these professionals are not able to property advise an owner on energy project financing.  Accordingly, many owners are not aware of, nor understand, the variety of financing mechanisms available to them.

Solution: Learn enough to realize that it is worth the time to learn about the options that are available, hire a sustainability consultant, architect or engineer to analyze the property, benchmark its energy and water usage and understand other maintenance practices, have the systems retro-commissioned to determine how well they are performing and develop an efficiency, sustainability and/or resiliency retrofit plan. Implement the plan and start realizing the benefits.

Is Your Building Conducive to the Installation of a Green Roof?

Any reason for installing green roofs on a building—whether it’s to save money or the environment—is a good reason.

By Richard Heller and Chris Psencik

According to the Green Roofs for Healthy Cities (GRHC) association, the North American green roof industry grew by a remarkable 24 percent in 2012. Part of this growth was spurred on by more cities recognizing the public benefits of green roofs and taking various policy measures to encourage their widespread installation. However, according to GRHC there is still enormous potential for growth of new green roofs on billions of square feet of buildings across North America.

Despite the potential, installing a green roof is not a decision to be taken lightly. There are several structural and site/location considerations to take into account. The most recent news of a probable green roof collapse at a Latvian supermarket should give one pause. Before allocating the time and resources, facility owners and managers should weigh the pros and cons of a green roof and what to keep in mind during the planning stages.

The Mental Checklist

First, you need to consider the load capabilities of the building. The space that is designated for the green roof: Is it able to sustain the weight for the items that will be designed and placed on top of the roof? If the live weight load (after snow, for example) is less than 35 pounds per square foot, it will be harder to establish a green roof.

Second, consider the design intent of the green roof. Is the space going to be an area that individuals will be able to visit and enjoy up close, or is the green roof only to be viewed from a window, door, patio, etc?

Third, take into account the location and climate of the intended green roof. A common misconception about green roofs is that they must always be green and vegetative, but there are several possibilities. However, one needs to consider the climate and the exposure. For example, the west side of a building is going to have a tremendous amount of sun and heat, so plant materials will need to be suited to sustain themselves in this environment. The north side will receive colder northern winds and can be more heavily impacted by freezing temperatures.

In many instances the natural environment is not the only factor to consider when designing a green roof environment. Microclimates will also be created from the structure surrounding the space. For instance, radiant heat will increase exponentially when planting next to mirrored glass. Overhangs will create opportunities for shade gardens. Planting soil depths and soil material makeup will determine how quickly or slowly a space will dry out in rainy or dry seasons.

Fourth, consider irrigation and drainage. Drainage is key in making sure that rooftop gardens do not become pools. Rock gardens are commonly used in situations where irrigation cannot be provided and temperatures are determined to be too extreme in a green roof environment. Draining and irrigation issues can be solved with construction, but this will add costs to any budget.

Finally, one must ask if a green roof is the best choice for achieving goals. Many of the functions of a green roof can be achieved through other means. For example, rainwater from roofs can be recycled for irrigation. Heat can be mitigated by shade trees, which are the backbone of the ecology and support far more beneficial insects than most green roofs ever will.

In an urban environment, where there is almost no ecology and nature has been paved over, green roofs can play a vital role. In a suburban environment, however, the functionality of green roofs may become harder to justify when one looks at other alternatives.

Green Roofs Expand Green Spaces

According to the Environmental Health Research Foundation, each day a 50-foot by 50-foot green space releases enough oxygen to support a family of four, and the Center for Disease Control and Prevention (CDC) points to the positive mental health benefits of being exposed to parks and green spaces.

Green roofs offer various opportunities for owners and employees to experience a little bit of nature. For example, the Fairmont Hotel in downtown Dallas developed a vegetable garden green roof, which allows the kitchen to provide fresh, locally grown herbs, spices and seasonal vegetables that go straight from the garden to the plate.

 

At the University of North Texas (UNT) Business Leadership building, a series of outdoor green roof spaces created by Southern Botanical and Lindsey White of Caye Cook and Associates allows students and faculty an opportunity to leave the classroom and office to take a break to reflect and study.

These spaces also help with the conservation of energy for the facility by increasing natural lighting within interior rooms and corridors. In turn, the increased natural light offers an opportunity to save on energy and lighting costs for the facility.

But there are also some concrete reasons for installing a green roof.

Green roofs can protect the roof membrane from elements that can be destructive, such as extreme heat and cold, water, mechanical damage and ultraviolet rays. In some cases, a green roof can double or triple the life of the membrane when properly installed and maintained.

Additionally, there are energy savings since a green roof acts as an insulator. Green roofs can also mitigate the heat island effect, reduce rainwater runoff, and to some extent, replace the flora that was destroyed by the footprint of the building.

For many cities, a compelling reason for green roofs is to offset the underlying, weak urban infrastructure that is overwhelmed by rainwater runoff.

New York City, for example, has an antiquated sewage system which, when overwhelmed by rainwater, forces the city to dump raw sewage into local bodies of water and makes New York beaches unusable for several days thereafter. In this instance, green roofs absorb 80 percent of the water that lands on them, so they can be a strategy to reduce the amount of water that reaches urban infrastructures.

Expecting Positive Growth for Green Roofs

The USGBC and its LEED certification program are spurring on the design and installation of green roofs all over the country. There are some regional variations, but that is often tied to climate. In Texas, for example, extreme temperatures can be somewhat of a limiting factor.

The increase in green roofs is often a matter of education, cost and technology, but signs indicate that they will become more productive and/or habitat-oriented. Green roofs will become popular as a site for food production, a habitat for beneficial insects, a way station for migratory birds and so on. This is a trend that is already happening in some cities and will continue to expand as food prices rise, and natural habitats continue to be reduced by population pressure.

And green roofs will continue to grow as a market segment as they establish track records and are supported by legislation.

For example, New York City gives a tax rebate for green roofs more than a certain square footage because the city recognizes that every square foot of green roof means less money it will have to spend upgrading the sewer and rainwater infrastructure.

In the end, consider function first and make sure your building and location are amenable to a green roof, or be clear on the extent of changes that need to be made and costs that need to be incurred for it to function properly and safely. Then be clear on the “why.” If the “why” is that you want to reap the qualitative benefits for employees and the environment, that is okay, too.
