Join us for this Ribbon Cutting to celebrate The Oaks at Rose Villa, Portland’s first Zero-Energy senior housing project!
The Oaks at Rose Villa is designed to significantly minimize environmental impacts through the following measures: 

• The homes incorporate a super-insulated, airtight building envelope for improved comfort that reduces the heating and cooling load by nearly 90 percent. This high-performance envelope allows the units to use low-load and high-performance mini-split HVAC systems for heating and cooling.
• Fresh, filtered air is continuously supplied to bedrooms and living spaces and extracted from bathrooms and kitchens through heat recovery ventilators. 
• State-of-the-art, energy-efficient, transcritical carbon dioxide (CO₂) hot water heat pumps are used to cut energy use by half from the next highest performance options currently on the market.  A transcritical heat pump uses CO₂ as the refrigerant, which also reduces the global warming potential of the system, compared to standard refrigerants.
• LED lighting and ENERGY STAR appliances throughout significantly reduce energy use.
• All buildings have triple-paned, tilt-turn operable windows for improved comfort and performance. They block out sound while allowing for plenty of natural light and fresh air.
• Green Guard and Living Building Challenge Declare-certified materials used throughout dramatically reduce potentially harmful chemicals in each home.
• Hard-surface flooring does not harbor dust mites, mold, household dust and debris, or harmful chemicals that can off-gas into the home over time.
• Advanced framing techniques reduce lumber use by 15 percent and reduce insulation voids, increasing energy efficiency.
• A rain-screen wall system increases the longevity of materials by preventing moisture from entering the wall cavity.
• WaterSense-certified showerheads, faucets and toilets significantly reduce water and energy use.
