Sustainability

At Bardessono we act on our environmental values. We believe that making progress on environmental issues comes, in part, from developing working models that provide examples to follow. Our model demonstrates two things:

• A hotel can provide a fully luxurious guest experience and be green at the same time, and;
• Environmental initiatives can be implemented in a manner that is practical, economic, and aesthetic.

Taking care of our environment is a core value at the Bardessono. We are committed to spreading the word about the importance of taking environmental actions and about our initiatives.

Our choice represents a departure within the hotel community. By minimizing the impacts of construction and design and integrating the most advanced environmental technologies, we charted an aggressive environmental course. Some of the initiatives are not obvious at first glance. An underground geothermal system heats and cools the guest rooms, the spa, and the domestic hot water supply. Almost no offsite energy is used. Hidden on the flat rooftops are 940 solar panels that provide significant amounts of the hotel’s electrical demand. Occupancy sensors in guest rooms automatically decrease energy consumption when guests are not in their rooms.

Gorgeous woods used throughout the hotel are milled from salvaged trees. Non-toxic, non-allergenic materials were used in construction. Environmentally friendly recycling and composting programs are standard. Products in the restaurant and spa are sourced primarily from local organic or sustainable producers. We are not perfect. Knowledge and budgets have limits to heed. But we hope our actions have provided worthy examples for others to try.

Even though much of what we have done remains hidden to the eye, our environmental commitments are reflected everywhere. The hotel has been designed to achieve the Leadership in Energy and Environmental Design’s (LEED) Platinum certification, the highest standard for environmental design, and to be as transparent as possible when it comes to the choices we’ve made and the values we stand by. Our design team created a list of environmental initiatives to address every aspect of Bardessono life, most of which we were able to implement.

Bardessono has an effective recycling and composting program. The goal, naturally, is to put as little material into the waste stream as possible. All planted areas are managed organically; vegetable food waste is composted in a “Terra Pure” tub and reused as organic compost for maintaining landscaped areas. The hotel utilizes organic and locally produced food products wherever and as often as possible. Mere steps from the restaurant kitchen, Lucy’s onsite, certified organic garden yields daily inspiration and ingredients to the Liquid Artists behind the bar at Lucy, utilizing fresh herbs and garnishes to create hand-crafted libations. Fruits, vegetables, and meats for the restaurant are supplied by local organic purveyors. Paper products used at the hotel have a high recycled content. Dispensers for shower products are used to avoid the excessive waste of small plastic bottles provided by most hotels. The bath products are completely organic and handmade. Laundering is done using organic detergents and water saving methods. Housecleaning staff use only organic products. Electric and hybrid vehicles are used by the hotel to minimize air pollution.

All glues, adhesives, finishes, paints, carpets and fabrics used at Bardessono are required to meet low volatile organic compounds (VOC) standards to vastly improve indoor air quality. Prior to putting furniture into the rooms, the rooms were ventilated with fans for several hours to remove residual construction odors. The use of plastic is minimized. Porcelain and concrete tiles are made of natural materials that can be recycled. The glass tiles have a high recycled glass content. The combination of low VOC compound materials, no carpeting and drapes, all organic linens, terry and cleaning supplies, greatly reduces any potential allergens in the rooms.

Indoors, bathroom fixtures with low water flow have been installed, along with dual flush toilets and waterless urinals. Outdoors, native and drought tolerant plants have been chosen for landscaping in order to minimize water demand. In turn, the drip irrigation system is also designed for maximum efficiency, minimizing water waste. All grey and black water is treated and recycled for irrigation use by the Town of Yountville.

One of the most pressing environmental needs is to reduce the demand for energy. The goal for the Bardessono project is to reduce the demand for external energy supplies — electricity, gas or oil by at least half of what a typical hotel consumes. Heating and cooling are the main sources of energy demand in a hotel. All the buildings are designed with overhangs to reduce the heat gain from the summer sun yet allow the winter sun’s rays to enter and warm the rooms. Each room has 200 square feet of glass to allow for natural lighting. The rooms have doors and windows opening onto private patios for natural ventilation. The glass used is all low-e which reduces the temperature transfer through the glass. When sensors detect that guests are not in their room, the automatically controlled thermostats allow the temperature to raise or lower a few degrees and reduce excess energy demand. When cooling is required, the first stage of intervention is for motor controlled exterior venetian blinds to lower to reduce the heat gain from the sun. While common in Europe, the United States has yet to adopt this approach; internal shades and drapes do almost nothing to keep out the heat from the sun. (Guests, of course, can over-ride the automatic system to raise and lower the shades as they need). Another method for reducing heat gain in the buildings is the use of reflective materials on the roofs that minimize heat absorption.

When additional heating or cooling in guest rooms is necessary, water is used from 72, 300-foot wells on the property. A ground source heat pump system was developed based on these wells. The temperature of the ground water is approximately 70 degrees in these wells. The water to air heat pumps only needs to change the temperature of this 70-degree water a few degrees to provide air in the guest rooms at the desired temperature. In a typical air to air heat pump, the pump is trying to change the outside air temperature, which in the hotel’s location can vary from 30 to 105-degree Fahrenheit, to the desired in room temperature. This amount of temperature change takes considerable energy. The ground source system also pre-heats domestic water to 120 degrees. The electricity used in this system is only for running the circulation and heat pumps. Building this system required significant capital investment but will pay for itself in lower energy bills.

The large amount of glass used in each building reduces the daytime requirement for electrical lighting. LED, halogen or fluorescent bulbs are used in light fixtures throughout the property. These lights use much less energy, generate less heat and last much longer than incandescent bulbs. Incandescent bulbs are used only when the more energy efficient bulbs are not available or suitable to their function. The amount of exterior up-lighting is minimized to limit light pollution. The same system that senses occupancy and adjusts thermostats in the guest rooms also turns off the lights when the rooms are unoccupied.

Solar energy is becoming part of the solution to excessive and destructive reliance on petroleum. At the hotel, the use of solar energy is maximized by covering roofs with the most efficient solar panels available. This 200-kilowatt solar energy system provides approximately one-half the total electrical energy requirement of the property. The solar panels lie flat on the rooftops, invisible to surrounding properties. While the solar installation was a major investment, with the current and anticipated price of electricity and the subsidies available for solar installations, the payback period is less than six to eight years.

When Steve and Pat Bardessono built their home on the property in the early 1970’s, they incorporated into it an existing stone building meant for wine storage. (An underground wine cellar was not possible due to the high-water table, so in the late 19th century their family built the aboveground stone “cellar”). The building was taken apart stone by stone and saved for reuse on the Bardessono exterior walls. The stone is a local limestone called Tufa. The large blocks of the Tufa stone have been sliced into tiles and used on both the exterior and interior of public spaces.

Salvaged Monterey Cypress has been milled into siding used on the exterior of several buildings. These are trees that otherwise would have been ground up or burned. Walnut trees that were pulled out by farmers at the end of their production life have been milled into the hotel’s flooring, rather than being burned. Veneers of the Walnut grace the entry doors into the guest rooms and to several public rooms. Redwood recycled from wine casks has been used on the ceilings of some of the public spaces within the hotel, and on several public room doors. Salvaged California Bay trees have become cut slabs for the desks in the guest rooms. The large tables in the public areas and dining room tables have all come from salvaged trees. The concrete used on the property has significant recycled fly ash content and the steel has a high recycled content. Many of the materials are sourced from within 500 miles of the project site to reduce the environmental impacts of deliveries. Landscaped features and permanent signage structures are made from rammed earth, celebrating the soils of Napa Valley. Constructing rammed earth structures involves the use of local soil that is then compressed inside plywood forms with water and a small amount of cement. When the forms are removed, the beautiful soil is expressed as a building material. This is an ancient method of construction used around world.

Development is held back from the creek a minimum of 35 feet and the area in between is landscaped with native riparian plants. The goal is to create a healthy vegetative environment for native animals and fish, as well as minimize any silting of the creek through runoff.
