depending on project, nbs, biophilic solutions or low tech solutions( indoor & outdoor) and of course passive design elements for buildings are essential to have high energy effeciency short ROI, and massive benefits- you see the impact/ difference immediately without adding energy consumption on top and reliance on its supply - this can be especially interesting for thermal comfort regulation of buildings / aesthetic is not threatened at all,- you just need to design from the beginning with this thinking, for retrofits there are plenty architects that are well skilled in modern, efficient and ecological architecture where the visual design is a cherry on top - useless design is OUT

??Opt for materials that serve dual purposes like insulation that also adds visual texture. Incorporate natural light with well-placed windows and energy-efficient LEDs that come in sleek designs. Add greenery to boost both style and indoor air quality. Prioritize smart solutions that save energy while keeping the look intact.

To balance energy efficiency and aesthetics on a tight budget, focus on multi-functional materials that insulate and look good. Use LED lighting for efficiency and design flexibility. Incorporate plants for natural beauty and air purification. Embrace passive design to reduce energy needs while enhancing space quality. Consider recycled materials for unique aesthetics and sustainability. These strategies can create an appealing, efficient design that's cost-effective in the long run while showcasing your commitment to sustainability.
