| 8.1 Energy consumption is periodically monitored. Weight: 1 [ ] yes [ ] no
An electric meter was installed to measure consumption.
Energy consumption is monitored monthly with a meter installed in the generator. Diesel consumption also reflects the amount of generator running time and electrical demand.
(Copy: diesel consumption chart)
Lapa Rios was designed for minimal impact. The determination of whether to add an electrical device depends on the amount of electricity available. The electrical plan demands need over want.
8.2 The hotel maintains a monthly record of energy consumption and the usage is statistically analyzed. Weight: 1 [ ] yes [ ] no
Energy consumption is monitored monthly through the generator’s metering system.
Management oversees the analysis of usage and educates staff how to keep their usage minimal.

8.3 The hotel has an energy usage plan with specific savings goals. Weight: 1 [ ] yes [ ] no
(Copy: energy conservation plan)
(See: signs for energy conservation by guests in the bungalows)
8.4 A person is responsible for managing the ongoing education about energy saving activities for both guests and employees. Weight: 1 [ ] yes [ ] no
Yes, Hans Pfister and Andrea Bonilla
(Copy: staff training)
8.5 The hotel maximizes its use of natural light. Weight: 1 [ ] yes [ ] no
Yes, through design and construction: 3 sides of the cabins use all natural lighting during daylight.
All workstations have large windows or are of open design for natural lighting during the day.
8.6 The hotel has a preventative maintenance program for all electrical equipment and systems. Weight: 2 [ ] yes [ ] no
All department heads have a checking routine of all electrical equipment.
(Copy: monthly maintenance routine)
The refrigeration, electrical generator, diesel trucks, etc. have separate professional maintenance contracts, apart from the Lapa Rios staff.
(See: Sico Refrigeration, Taller Secundino, Font)
8.7 The hotel promotes the turning off of lights whenever they are not needed. Weight: 1 [ ] yes [ ] no
Reception employees explain minimum electrical supply/usage during the guest orientation, encouraging guests to turn off lights and fans when unnecessary.
(Copy: orientation topics)
(See: signs in the rooms and employee areas)
8.8 The hotel uses energy efficient light bulbs in at least 80% of the hotel’s facilities. Weight: 2 [ ] yes [ ] no
The entire hotel is minimally lighted.
The hotel uses no more than 50% energy efficient light bulbs, as generator efficiency must meet a minimum demand, or 1/3-load-capacity. The demand created from 80% energy efficient bulbs is not enough and the low draw would result in a damaged generator:
(Copy: bulb placement charts)
11-watt energy saving bulbs are used in those areas where the bulbs are used continuously for more than 6 hours: kitchen, office, staff common areas and pathway/cabin out-lights. (In the Osa these bulbs have all been painted yellow to cut down on insect attraction.)
The restaurant has been illuminated using only eight 40-watt reflector bulbs. Each table has candle supplementation.
Cabins have some 40-watt bulbs with 11-watt bulbs for general light.
Staff night lighting at the dormitories/ranchito is with 11-watt energy saving bulbs
8.9 Energy efficient electric equipment is used to meet at least 50% of the hotel’s needs. Weight: 2 [ ] yes [ ] no
Refrigerators and freezers have been designed and built especially for Lapa Rios using 4—5-inch foam walls, thereby cutting down the need to run the motor excessively.
the kitchen refrigerator has 4 small doors to minimize cool air loss
motors were placed on the top of the refrigerators allowing the heat from the motor to escape above the unit and out the roof.
(Copy: Sico report)
All fans operate by switch, making it easier for guests and staff to shut off fans and lights at the same time.
The dryers, washer, computers and ice machine have automatic cut off switches when they receive insufficient current from the generator. These cut offs warn the management about the supply problem, minimizing the stress to the small motors.
Each generator produces energy efficient 440-watts of power that is distributed in 3 phases and balanced to handle the long run load (project stretches over 1.4-kilometers). Many transformers convert power to 110-watts. When balancing the load to the generator the design was created considering: when and at what time each day each machine is using electricity.
8.10 The hotel uses alternative energy sources for lighting, such as solar panels. Weight: 3 [ ] yes [ ] no
A photovoltaic system illuminates and powers both the Carbonera and Rio Oro schools, electrical projects that Lapa Rios built and donated to the community.
Hydropower was professionally researched and considered both in 1991, 1998 and again in 2003. All studies show that the terrain around the lodge is not suitable for cost-effective hydropower lacking sufficient water throughout the year.
(See: Jason Borner, in Pto. Jiménez)
8.11 The hotel uses alternative energy sources for heating or pumping water, or other energy needs. Weight: 3 [ ] yes [ ] no
There are 6 solar convection panels for heating water.
There are 9 gas ‘on demand’ water heaters supplementing hot water to the cabins. The heaters have no pilot light and ignite with a “D” battery.
8.12 The hot water tanks and/or exposed pipes are covered with insulating materials to avoid heat loss. Weight: 1 [ ] yes [ ] no
Yes.
8.13 The hotel uses natural breezes, shade covering and other alternative air conditioning systems. Weight: 1 [ ] yes [ ] no
The (deforested) building site location was based on most available breeze collection.
Lapa Rios has no air conditioning. Local, traditional cooling technology—woven indigenous palm leaves that allow air to rise and vent—is the most energy efficient roof material in the tropics.
There are few solid walls. To maximize airflow and eliminate the need for air conditioning all sides of every building have screens, open for breezes.
8.14 The hotel uses technologies that increase the efficiency of the refrigeration and air conditioning systems. Weight: 2 [ ] yes [ ] no [ ] n/a
All refrigerators and freezers have been house-designed and built using 4-5” foam walls, thereby cutting power use. Refrigerators have 4 small doors to minimize cooling loss and cut down on energy use. All units have motors on top to permit heat escape above the cooling unit.
A walk in cooler to store fresh produce was created by enclosing an unused poolside bar with 6-inch insulating foam, installing an energy efficient 5,000 BTU air conditioner was placed in an unused patio bar/storeroom to create a walk in cooler for fruits and vegetables and the walls and ceiling were lined with 6-inch insulating foam.
A new energy-efficient air conditioner was purchased for the office in Pto. Jiménez office, decreasing energy consumption from the grid.
A 5 cubic meter ice chest (holding 2 large ice blocks) was designed in-house for the long haul truck. The box walls have 5-inch foam insulation and shelves. The cooler transports 16 huge plastic boxes of fresh produce and perishables over 400 kilometers without any food loss.

8.15 The hotel maintains a strict control on any air or gas leakage in its cooling systems. Weight: 2 [ ] yes [ ] no [ ] n/a
The monthly professional inspection requires checking of seals, motor functionality, gas levels, etc. This inspection is management monitored.
(Copy: monthly maintenance routine)
8.16 Efficient electrical equipment is used for at least 50% of hotel’s needs. Weight: 2 [ ] yes [ ] no
All refrigeration motors are placed above the unit to evacuate the heat above the cooling area.
(Copy: Sico report)
All laundry equipment is labeled highly efficient.
The largest machines (washer and dryer) are wired three-phase, 220-watt electricity, the most efficient use of electricity.
(See: laundry equipment)
The swimming pool pump is over-sized for 30,000 gallons of water, only pumping a few hours each day.
(See: pool pump)
Low watt bulbs are used in all areas where lighting is needed 6 continuous hours.
8.17 The hotel laundry takes advantage of solar heat to dry clothes, sheets and towels. Weight: 2 [ ] yes [ ] no [ ] n/a
Weather permitting sheets and towels are line-dried. Towels are dryer fluffed 5 minutes.
An industrial 50-pound load propane gas dryer serves the hotel, secondary to the sun. |
