Pioneer of a sustainable future!
LDL 1 was the first generation of affordable senior housing pioneered by Rob Roy, and Pacific Crest Group. This project was told, "It can't be done." An affordable housing that is absolutely green to the core... Yet it has been done!

LDL 1 was the first generation of affordable senior housing pioneered by Rob Roy, and Pacific Crest Group. This project was told, "It can't be done." An affordable housing that is absolutely green to the core... Yet it has been done!
Building Envelope:
- Passive solar Passive solar design minimizes heating and cooling costs and optimizes the performance of the solar thermal and solar photovoltaic systems.
- ICF exterior walls Structures with Insulated Concrete Form (ICF) walls require 44% less energy to heat and 32% less energy to cool.
- Roof design High heel trusses reduce heat loss and ventilated cold attic reduces the building’s cooling load.
- Windows The Milgard windows exceed Energy Star qualifications by 25% and reduce sound and UV transmission.
- Interior finishes All carpets are recyclable and paints are low VOC (Volatile Organic Compound)
Heating and cooling:
- Geothermal The ground source heat pump system utilizes 16,000 feet of underground tubing and five heat pumps to transfer heat from the ground into the building in the winter, and from the building to the ground in the summer. The system reduces energy use by 110,000 kWh per year compared to PTAC units, and by 273,000 kWh per year compared to electric resistance heaters.
- HRV System The heat recovery ventilation system recovers about 70% – 80% of the heat that is exiting the building air and delivers that energy back into the incoming air.
- Pellet Stove The pellet stove in the community room generates 60,000 BTUs of heat per hour using a variety of wood by-products collected at local sawmills.
Solar:
- Solar Thermal Twelve solar thermal panels on the roof and an 400 gallon storage tank satisfy 65% of all domestic hot water needs of the building; a centralized hot water system with an energy efficient boiler save 14,000kwh per year.
- Solar Photovoltaic The 24 kW rooftop system generates 38,000 kWh per year and satisfies 20% of the building’s electrical needs.
Electrical:
- Lighting High efficiency compact fluorescent and LED lighting significantly reduces electrical energy use; fourteen common area Solatubes provide attractive natural light, further reducing energy use.
- Appliances Energy Star refrigerators and dishwashers save approximately 4,750 kWh per year; Energy Star washers and dryers save approximately 3,000 kWh per year.
Water Conservation:
- Plumbing Fixtures Dual flush toilets save approximately 35,000 gallons of water per year, front-load washing machines save approximately 22,000 gallons per year, and low-flow shower heads and faucets reduce water consumption by 30%.
- Grey Water Little Deschutes Lodge is the first multi-family building in Oregon to be approved for grey water circulation. Grey water comprises 50% – 80% of residential wastewater and can be reused flushing toilets, landscape irrigation, and other purposes.
- Rain Harvesting Rainwater is collected in 12 rain barrels that can store 60 gallons of water each. The water is used to irrigate 12 raised bed gardens in which residents grow edibles and ornamental plants.
- Stormwater Two bioswales capture the storm water runoff from the parking lot, which was designed to minimize the impenetrable surface area, retain as much natural drainage as possible, and reduce the creation of heat islands.
- Landscaping Native plant material was used for the landscaping and will require no irrigation after the first 2 years.
- Living Machine When installed, this natural wastewater treatment system will use living plants and microorganisms to turn wastewater into clean water that is reusable for irrigation, toilet flushing and other purposes. Since up to 95% of water usage goes to applications like these, the Living Machine can make an enormous difference in reducing water consumption.
