Energy Efficiency

Design spaces with energy efficiency in mind. Incorporate natural lighting to reduce the need for artificial lighting during the day. Maximize the use of windows and skylights, and consider installing energy-efficient lighting fixtures such as LED bulbs. Specify energy-efficient appliances and equipment, including HVAC systems, that consume less energy and have higher performance ratings.


Lighting accounts for an important portion of a building’s energy consumption. Opt for energy-efficient lighting solutions such as LED (Light Emitting Diode) bulbs, which use significantly less energy and have a longer lifespan than traditional incandescent bulbs. Incorporate natural lighting by maximizing the use of windows, skylights, and light shelves to reduce the need for artificial lighting during daylight hours.

Natural Ventilation

Design spaces to maximize natural ventilation whenever possible. Properly positioned windows, operable skylights, and strategically placed vents can facilitate the movement of fresh air, reducing reliance on mechanical ventilation systems. It saves energy and improves indoor air quality and occupant comfort.


Effective insulation plays a crucial role in reducing heating and cooling demands. Choose insulation materials with high thermal resistance, such as fiberglass, cellulose, or spray foam insulation. Insulate walls, floors, and roofs to prevent heat transfer, keeping spaces comfortable year-round while minimizing reliance on heating and cooling systems.

Water Conservation

Implement water-saving strategies to reduce water consumption. Specify low-flow faucets, showerheads, and toilets to minimize water usage. Incorporate rainwater harvesting systems or graywater recycling systems for irrigation purposes. Design spaces encouraging water-efficient habits, such as incorporating sensor-controlled faucets and dual-flush toilets.

Efficient Plumbing Fixtures

Select plumbing fixtures that are designed to minimize water usage. Install low-flow faucets, showerheads, and toilets that meet or exceed industry standards for water efficiency. These fixtures reduce water consumption without compromising functionality or user experience, helping to conserve water with every use.

Water-Efficient Appliances

Specify water-efficient appliances like dishwashers and washing machines with high water efficiency ratings. Look for appliances with adjustable water levels, eco-friendly wash cycles, and sensors that optimize water usage based on load size. These appliances help minimize water waste while maintaining performance.

Greywater Systems

Consider incorporating greywater systems that capture and reuse water from sinks, showers, and washing machines. Greywater can be treated and recycled for irrigation, toilet flushing, or non-potable water use. Implementing greywater systems reduces the demand for fresh water and helps maximize water efficiency within the built environment.

Indoor Air Quality

Prioritize indoor air quality by selecting low VOC (Volatile Organic Compounds) materials and finishes. VOCs are harmful chemicals that many building materials, furniture, and household products emit. Opt for products tested and certified for low emissions, promoting healthier indoor air quality. Incorporate proper ventilation systems to improve air circulation and reduce the buildup of indoor pollutants.


Proper ventilation is essential for maintaining good IAQ — design spaces to incorporate adequate fresh air intake and efficient air circulation. Consider natural ventilation options that exchange indoor and outdoor air, such as operable windows or skylights. Additionally, mechanical ventilation systems with high-quality filters can help remove pollutants and provide a consistent fresh air supply.

Natural and Sustainable Materials

Incorporate natural and sustainable materials into interior design. Choose materials that have minimal chemical treatments and are free from harmful substances. Consider using natural wood, stone, bamboo, or cork flooring options. Natural materials enhance IAQ and add warmth and beauty to the space.

Proper Moisture Control

Moisture-related issues can lead to mold growth and poor IAQ. When creating interior spaces, it is important to implement moisture control strategies that encompass reliable waterproofing, sufficient ventilation in moisture-prone areas, and moisture-resistant materials. To prevent mold and mildew, promptly monitor and address water leaks or excess moisture.

Sustainable Furniture and Accessories

Choose furniture and accessories that are sustainably produced. Look for items made from recycled or upcycled materials. Consider vintage or antique pieces that give a second life to existing furniture. Support local artisans and craftsmen who prioritize sustainable practices. Avoid products that contribute to deforestation or unethical labor practices.

Material Selection

Choose furniture and accessories made from sustainable and renewable materials. Look for items crafted from responsibly sourced wood, such as FSC-certified (Forest Stewardship Council) or reclaimed wood. Consider alternatives to wood, such as bamboo, rattan, or cork, which are fast-growing and highly sustainable options. Avoid materials derived from endangered species or those that involve harmful extraction practices.

Recycled and Upcycled Pieces

Consider furniture and accessories that are made from recycled or upcycled materials. Look for items created from reclaimed wood, recycled metal, or repurposed materials. Upcycled pieces give new life to old items, reducing the need for new production and minimizing waste.

Non-Toxic Finishes and Adhesives

Choose furniture and accessories finished with non-toxic and low-VOC (Volatile Organic Compounds) coatings or paints. These finishes minimize the off-gassing of harmful chemicals into the air, improving indoor air quality. Additionally, opt for items assembled with non-toxic adhesives and glues.

Recycling and Waste Management

Design spaces with recycling and waste management in mind. Incorporate designated recycling bins and provide clear instructions for sorting recyclable materials. Integrate storage solutions that facilitate waste separation and composting. Specify easily recyclable or biodegradable materials, reducing the environmental impact at the end of their lifecycle.
