More Conscious Travelers, Climate Concerns Impacting Accommodation Design

More Conscious Travelers, Climate Concerns Impacting Accommodation Design

In a race to avert the climate crisis, the tourism industry is evolving. More travelers decide to keep their feet on the ground; the industry responded with flight-free services and itineraries. Concerned with how the climate impacts biodiversity and wilderness areas, many tour operators began actively supporting carbon reduction and rewilding programs. It turns out that where travelers finally lay their heads at the end of a busy day affects the climate, as well.

According to research conducted by the Sustainable Hospitality Alliance, “The hotel industry needs to reduce its carbon emissions by 66 percent per room by 2030 and 90 percent per room by 2050 to ensure that the growth forecast for the industry does not lead to a corresponding increase in carbon emissions.”

Responding to regulatory changes, consumer preferences and proactive climate commitments, hotel chains and independently owned accommodations are making changes — though at varying speeds and to differing degrees. This includes pursuing LEED certification, shifting to renewable energy, and reducing waste and water consumption, among other actions.

“When I designed our first villa, Villa Punto de Vista, that was back in 2007 — just after the release of Al Gore’s An Inconvenient Truth — so I was already in tune with the concept of a warming planet and designed the building with an eco-conscious mindset,” said David Konwiser, co-founder and architect of the Costa Rica property. “However, ten years later and after seeing the devastating storms and worsening drought ravage our planet over that next decade, I designed our second villa (Villa La Isla) with even more emphasis on carbon neutrality.”

From natural fiber ceilings produced by Indigenous Peoples living in Costa Rica’s mountains to the microfiber bedding made from recycled plastic bags, nearly every square inch of the property reflects Konwiser’s climate concerns. “The villas’ materials and finishes had to be of premium quality, ecologically sourced, and surpass the challenging esthetic and safety expectations of the world’s most discerning travelers,” he said.

Villa Punto de Vista certainly isn’t the only property built from the ground up with the climate top of mind. In fact, there’s been a wave of them lately: Svart — a luxury property in Norway expected to open in 2024 — is said to be the first off-grid, energy-positive resort. The recently opened Hotel Marcel in New Haven, Connecticut, is completely powered by solar electricity.

Similarly, Populus — a 265-room hotel currently under construction in Denver, Colorado — is being billed as the first carbon-positive hotel in the US. It features window “lids” that provide shade while improving energy performance and a roof terrace planted with regional vegetation intended to attract local wildlife and insects.

Critics of “sustainable” buildings rightly point out that an eco-friendly, resource-efficient building is one thing; but construction itself has a massive carbon footprint. As noted in a 2022 Bloomberg article, the Marcel may be designated LEED Platinum; but on its way to being the US’s first net-zero-emissions hotel, its calculations failed to include embodied carbon — which includes all the greenhouse gases emitted during renovation, construction, demolition and disposal of a building.

According to Transforming Existing Hotels to Net-Zero Carbon, a guide developed by four companies including IHG Hotels & Resorts, embodied carbon makes up between 30 and 70 percent of a typical building’s total lifecycle emissions. Further, approximately 80 percent of the buildings that will be in use in 2050 are already in existence today.

“Adapting and retrofitting existing buildings to lower GHG emissions is critical and needs to be embraced as part of the hotel sector’s ‘Routemap to Zero Carbon,’ particularly as expectations of hotel investors, owners, staff, and guests shift towards greener, more sustainable models of investment, business operation, and living,” noted Gillian Breen, director of Gleeds at the time of Transforming Existing Hotels’ publication.

The natural solution for most properties, then, is to renovate existing buildings with an eye on sustainability. For example, Hotel Belmar — located in Costa Rica’s Monteverde cloud forest — was built in 1985 with environmental stewardship, cultural appreciation and economic benefits for the local community in mind. Upgrades nearly 30 years later further reduced its environmental footprint.

“The 2012 renovation of Hotel Belmar kept our traditional wooden architecture; but we adapted most rooms, some bathrooms and hallways to have floor-to-ceiling windows, skylights and big sliding glass doors,” said Pedro Belmar, CEO and general manager of the hotel. This increased lighting efficiency and ventilation, and decreased energy consumption. Property owners also invested in solar panels, upgraded water-treatment systems and installed rain-collector systems.

Regardless of whether properties are renovated or built more sustainably (while accounting for embodied carbon), time is of the essence when it comes to making climate-conscious accommodations an industry standard.

“It is widely acknowledged that this decade needs to be one of climate action,” wrote Simon Gill, hotels and leisure business leader for UKIMEA at Arup, in his forward to Transforming Existing Hotels. “Without taking bold steps now, we will not be able to achieve the net-zero carbon target set for 2050 and avert climate catastrophe.”

Tech and Ingenuity Supercharge a Sustainable Hotel

Tech and Ingenuity Supercharge a Sustainable Hotel

Automation, emissions analysis, upgraded technology, cloud computing, and artificial intelligence – these are just a handful of ways that businesses are promoting sustainability and reducing greenhouse gasses.

Hotel Marcel, based in New Haven. Conn., wants to lead the way when it comes to sustainability in the hospitality sector. With this goal in mind, a team of eco-conscious design, architecture, and technology experts have built the first net-zero hotel in the United States. Hotel Marcel is also one of only 10 LEED (Leadership in Energy and Environmental Design) Platinum-certified hotels in the country. Since its opening in 2022, the hotel has won countless awards related to its sustainability.

Hotel Marcel had a long life before becoming what it is today. It started life as the Armstrong Rubber Company Building in 1968. After a period of vacancy started in the late 1990s, the building was listed on the Connecticut Register of Historical Places in 2020 and then the National Register of Historical Places in 2021. Those designations added challenges for converting the building into an eco-friendly hotel. But with a steadfast vision by lead architect, developer, and owner Bruce Becker, along with partner Sinclair Digital, the hotel is now a model for those that follow.

 

Renovated Hotel Relies on Renewable Energy and Microgrid Technology

The details are impressive. The hotel reused as much of the existing infrastructure as possible during a full renovation. To meet its goal of generating all its power, the hotel relies on renewable solar power onsite to produce electricity for the entire property. Engineers also installed triple-glazed windows for efficient insulation; a heat pump system for hot water, space heating, and cooling; and elevators that generate their own electricity. Even the hotel’s laundry room runs on renewable electricity instead of natural gas.

While some of these measures, like coated windows and renewable building materials, were right in Becker’s wheelhouse, other, more technology-driven features were less so. Early in the process, Becker’s team installed an energy-efficient, DC-powered microgrid for the hotel’s converters, microcontrollers, and batteries. The localized, solar-powered DC microgrid runs independently of the main power grid and is powered by an Ageto ARC controller, which enables grid services and resilience sequencing.

Becker knew from learning about other sustainable hotel endeavors like the Sinclair Hotel of Fort Worth, Texas, that low-voltage Power over Ethernet (Poe) would make a significant difference. Unlike high voltage power, low voltage uses less electrical current and sends power and controls on the same cable, reducing the amount of infrastructure required and resulting in greater energy efficiency. These systems also operate at levels of as low as 24 volts, making them safer and installable without an electrician.

“Our engineers visited the Sinclair Hotel to see how PoE would work in a hotel setting,” Becker said. “We were very keen on using it for lighting and intelligent occupancy sensors and integrating it with mechanical blackout and sheer shades to create quiet, dark, and efficient rooms.”

 

Installing Lantronix Switches

At the same time, the Sinclair organization, now called Sinclair Digital, was expanding from its role as a traditional hotel developer to a consultant that partners with hotel developers to choose and implement PoE and other energy-saving technologies.

To enable PoE throughout Hotel Marcel, Sinclair Digital advised implementing Lantronix’s Smart Managed Gigabit PoE++ switch, which would support direct, high-voltage DC power and the latest PoE standard.

“After we did the Hotel Sinclair, we learned about Lantronix,” explained Sinclair Digital COO Hannah Walker. “We knew that it was increasing the power of its technology to 90 watts as opposed to 60 watts, which meant that if you had a network switch with 24 ports, you can now pass 90 watts per port, which gives you a lot of capacity.”

In keeping with the low-voltage theme, Sinclair also installed VoltServer Digital Electricity to power the Lantronix switches. This enables the switches to safely transport DC power at high wattages over long distances on Class 2 wiring. Digital Electricity is a low-voltage technology but has the power and distance capabilities of AC by splitting energy into packets and transmitting them every second by the hundreds from a transmitter to a receiver unit.

Racks of switches now populate four original electrical closets throughout the property, connected via fiber run between the floors. The switches power lighting and motorized window treatments and are integrated with the HVAC system. Becker said that the hotel’s 55 PoE++ switches have reduced lighting energy use by more than 30%.

 

Emergency Battery Backup System

Next up was comprehensive emergency battery backup for the entire hotel, including emergency lighting, elevators, and stairway pressurization. While emergency battery backup was a fairly new concept, Walker recommended going the extra mile because of its significant energy savings.

“All of the systems we use today in buildings are DC inside, so all renewable energy generates in DC,” Walker explained. “But every time you transport it in AC, you lose 15% of efficiency, and it adds up.”

The team chose a battery developed by Sinclair and LG Electronics. The massive Lithium Ion battery, designed to replace energy-hogging diesel generators, can be recharged with solar panels via a microgrid.

 

Grand Opening

With everything in place, the hotel opened last spring. Five-star ratings populate virtually every hotel booking and review site.

Becker ensured all systems were metered to help the hotel stay on track with its sustainability goals and LEED Platinum requirements. Both the Lantronix and VoltServer equipment have in-line metering capabilities and associated software. Becker and Walker will consider adding an energy monitoring system to better determine energy usage at all points and so guests can see how much energy their rooms save.

With its focus on sustainability practices, it’s unsurprising that Hotel Marcel continues to break barriers. Today, it’s on the cusp of being certified as the only Passive House hotel in the United States. Passive House, which focuses on building energy and efficiency, is a well-established standard in Europe and is gaining popularity in the U.S.

What does it mean for a hotel to be carbon neutral?

What does it mean for a hotel to be carbon neutral?

Renderings of the Six Senses Svart in Norway are straight out of a sci-fi movie. An overwater hotel shaped like a wheel glows at the foot of a glacier – the Svartisen glacier in the Holandsfjorden fjord, to be specific – like a space station floating in orbit.

If all goes according to plan, the otherworldly image will come to life in 2024 as the first carbon-neutral and emission-free resort (Six Senses has not yet broken ground on the project), joining an emerging movement of carbon-conscious hotels.

In Turkey, the Stay Hotels says it is the country’s first carbon-neutral hotel group. In Denver, construction is underway on Populus, a 265-room property that claims it will be the United States’ first “carbon positive” hotel when it opens in late 2023. In New Haven, Connecticut, Hotel Marcel, opened in April, is the first US net-zero hotel.

Hotels contribute about 1% to global carbon emissions, says Claire Whitely, head of environment for the Sustainable Hospitality Alliance charity.

Of the 36.3 billion tonnes of carbon dioxide emitted worldwide last year, that would mean hotels contributed roughly 363 million tonnes – about as much as it takes to power about 45.7 million homes for a year.

There are more than 90,000 hotels in the United States using energy on air conditioning and heating; laundering towels and sheets; lighting rooms and lobbies; and refrigerating the mini bar – not to mention the energy and resources to build and furnish them.

 

Parkroyal on Pickering in Singapore calls itself the world’s first “hotel in a garden”.

 

“We are talking about properties that are operated 24/7 and talking about over a billion hotel nights,” says Peter Templeton, interim president and CEO of the U.S. Green Building Council.

The carbon-neutral and carbon-positive labels sound good on paper, but some experts question if they are more performative than productive. Travel industry experts and climate scientists explained what travellers should know about the new wave of ‘green’ hotels and how to pick one.

 

 

What does it mean to be carbon neutral?

When hotels says they’re carbon neutral, they usually mean they are taking the same amount of carbon dioxide out of the atmosphere as they emit. Christoph Meinrenken, a physicist at the Columbia University Climate School says technically the term should be net carbon neutral, as true carbon neutral would mean having zero carbon emissions – but carbon neutral is more commonly used.

That is often done through carbon offsets, which account for a person, business or government’s carbon emissions by removing carbon from the atmosphere. This can be done in several ways, such as planting enough trees to capture the amount of carbon dioxide the hotel emits, or financing renewable energy projects or reforestation.

Some hotels may not necessarily have “green” operations; they just buy offsets. Other hotels become net carbon neutral by being more energy-efficient, then covering the rest of their emissions through carbon offsetting. For example, at the all-electric Hotel Marcel, 100% of its electricity is produced by solar panels on-site.

While it will cost hotels to make green changes, “it’s not going to cost much extra to do now that so many [green] strategies are becoming more and more commonplace,” says Peter Rumsey, founder and CEO of Point Energy Innovations, a building-systems and renewable-energy engineering company.

Rumsey says hotels can become more energy efficient for less money these days with solutions that are readily available, such as LED lighting, induction cooktops and management systems with sensors that make sure energy is being used efficiently.

Whitely agrees. “The technology that we need to decarbonise the hotel industry is here,” she says. “We just need to put it into place.”

 

What about carbon positive and net zero?

Carbon negative, energy positive or climate positive refer to a hotel offsetting more carbon than it emits. The term carbon positive is sometimes used in the same context, although the term is counterintuitive; we want less carbon, not more. “Some people use it in marketing, but technically, it doesn’t make sense,” Meinrenken says.

A property may strive to do this by producing more renewable energy than it needs, or make up for the carbon used in the construction of the hotel, not just daily operations.

Svart’s proposed design is an example. The hotel and its adjacent services, such as boat shuttles and guest activities, plan to be self-sufficient in electricity, water and waste management. It will also create a surplus of renewable energy using solar panels and geothermal wells to offset the carbon associated with the building’s construction.

To make Populus climate positive, Grant McCargo, founder, CEO and chief environmental officer of Urban Villages, says they’re planting trees to offset the carbon cost of the hotel’s construction and operations. They are also using a low-carbon concrete mix and installing windows with “lids” designed to reduce the hotel’s energy needs and require less washing. They also omitted a parking lot to encourage visitors to use public transportation.

Properties claiming to be net-zero mean they are offsetting all of their greenhouse gas emissions – methane, nitrous oxide, among others – not only carbon.

Templeton has seen thousands of projects move toward green building certification such as LEED or Passive House, with some embracing the concepts of zero energy or zero waste. He expects more to come, particularly as new policies incentivize greener choices.

 

Criticism of carbon claims

Critics say pledges such as carbon neutral and net zero don’t always accurately factor the full scope of emissions. Others are wary of their legitimacy.

Then there’s the concern that a hotel may have noble sustainability goals but doesn’t stick to them.

“Once you put the label of green or sustainable on something, many people tend to stop asking questions,” says Robert Krueger, a sustainability expert who created the Environmental & Sustainability Studies program at Worcester Polytechnic Institute.

“The architects and engineers work to create a building on paper that works a certain way. But when you put people into that building, it changes the way it functions,” Krueger says.

Rumsey says buying carbon offsets can be a good thing, but it shouldn’t be considered a final solution to hotel sustainability concerns.

“That’s just sort of a temporary Band-Aid approach,” he says. “At the end of the day, we can’t buy our carbon-way out of climate change through offsets. These hotels and these flights have got to change their emissions in a fundamental way.”

How travellers can do their research

Rumsey doesn’t think it’s up to consumers to fix the problem, but the hotels that travellers choose can influence the industry.

While shopping for a place to stay, Meinrenken says travellers should scrutinise a hotel’s sustainability claims. Consider it a red flag if a hotel claims to be green, eco-friendly or carbon neutral but offers no explanation on how.

“Usually, architects are proud of their designs, and the website will describe whether that hotel is off the grid or whether it uses solar panels on the roof, whether it’s a Passive House design, which would indicate very low intrinsic energy consumption, etc.,” Meinrenken says.

As for digging into what offsets a hotel uses, it may be difficult for a traveller to research whether the claims hold up. “Unless they voluntarily disclose that, it’s probably difficult to find out – too much work for travelers,” Meinrenken says.

Of course, greener hotel choices aren’t the only considerations travellers should be making.

“The most significant emissions associated with travel involve lifting a couple hundred people to 30,000 feet and propelling them to their destination at 500mph,” Michael Wara, director of Stanford University’s Climate and Energy Policy Program, said in an email.

“But making the hotels more sustainable can’t hurt and changing people’s perception of what luxury feels like can be very significant in terms of moving policy,” Wara added.

Ultimately, it’s not just about greenhouse gases. Meinrenken says it is also important to be concerned whether a hotel treats its workers fairly, whether it destroyed an ecosystem where it was built and whether it contributes to the community or just takes its resources.

Krueger recommends supporting social causes as well, and taking steps such as setting your own carbon emissions budget and making compromises to offset your trip (e.g., biking or taking public transportation to work).
