Comfort is found in the coolness of a shadow.
- Louis I. Kahn


We specialize in high performance buildings, providing architectural consulting, design and research with a focus on energy efficiency and sustainability. Our consulting services include: daylighting, shading, lighting design, energy modeling, alternative energy sources, glazing specification, high performance facades, sustainability, and LEED and CHPS certification. Our perspective integrates both architectural and engineering approaches to building design which enables us to work collaboratively with our clients and as part of an integrated process with design teams in an iterative process moving between technical analysis, research, and the generation of designs. 

Loisos + Ubbelohde projects have received 33 AIA awards, three AIA/COTE Top Ten Green Projects, and six LEED platinum certifications. Two completed buildings and four under construction are net-zero energy buildings. 

Our twelve-person firm includes six registered architects, two Building Energy Modeling Professionals (BEMP), three NCQLP Lighting Certified (LC) lighting designers, one National Fire Protection Association (NFPA) certified architect, and eight LEED Accredited Professionals (LEED AP). Our firm and staff are members of the American Institute of Architects (AIA), the US Green Building Council (USGBC), the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE), the Collaborative for High Performance Schools (CHPS), the American Solar Energy Society (ASES) and the Illuminating Engineering Society of North America (IESNA). Four of our firm members also serve as faculty at the University of California, Berkeley, and the California College of the Arts in San Francisco. For over three decades the principals have been at the forefront of university and industry-sponsored research.

We ask a building to create pure air, water and soil, store rainwater and solar energy, produce food, consume its own wastes, maintain itself, provide wildlife habitat, match nature's cycles, moderate local weather and be beautiful. Looking to natural and biological processes, sometimes called "biomimicry," can offer elegant, ecological and sophisticated models for the design and operation of buildings and sites. "Biophilia," or the profound love of the natural world, is another crucial basis for sustainable design. To connect to nature, we design buildings that open to daylight and natural ventilation. We bring the indoors and outdoors into close relationship while providing refuge from extreme conditions, whether they are natural, such as a hot summer afternoon, or social, such as traffic noise and chaos. A building should provide a place to live comfortably and with awareness between the earth and sky. We firmly believe that buildings which are generous in spirit and space and are made with natural materials and quality of workmanship are those which last over time. They most easily accommodate change and reuse and, most importantly, hold the affection and continued investment of the community.

We believe sustainable practice must be an integral part of our work. Our office employs electric lighting on daylight dimming and occupancy sensors, window shades on automatic controls, and increased insulation and ceiling fans to regulate temperature. We are a carbon-neutral firm; the majority of our office commutes by bicycle and all of the firm's air and car travel is offset. As a Bay Area Green Business we use recycled paper products, recycle and compost our waste, use a green cleaning service for the office, and buy organic produce and sustainable products. Sustainability education is also foundational to the mission of Loisos + Ubbelohde: we teach seminars, publish and present our research at symposia around the world, and the office actively supports continuing education for all staff.
