Mr. Saxena is an Associate Director at the Heschong Mahone Group.  His work includes building energy research and analysis; energy simulation; design consulting on various aspects of energy efficiency, especially daylighting; codes and standards development; and energy monitoring and field assessment. At HMG, his work has largely impacted national and state level energy codes, energy efficiency programs, daylighting research, as well as energy efficiency in individual buildings. His primary responsibilities are project management and leading research and analysis teams on various projects.

Mr. Saxena currently manages the Daylight Metrics project, and Potential Office Daylighting project funded under the PIER Lighting Program (LRP2). The Daylight Metrics project is an extensive research effort to define a new metric for daylighting in building and the Potential Office Daylighting project is an energy analysis and market research effort to determine the potential savings from daylighting through windows in office buildings. Mr. Saxena is also managing the PG&E’s Emerging Technologies project on Advanced Skylights. The project involves measurement of energy savings on-site for evaluation of the additional benefit due to skylights with advanced optics for better daylighting. The research effort involves on-site energy monitoring, data collection, analysis and daylighting and energy simulation .

Mr. Saxena has headed various projects for code and standards enhancement studies. These studies involved extensive research, analysis and hand-holding support during the code change process. These include various code change proposals exploring energy use and potential savings in domestic hot water usage in multi-family buildings and lighting and daylighting in commercial buildings. Mr. Saxena headed the research team that lead to California's Title 24 2005, 2008 and ASHRAE 90.1 2010 requirements for skylighting. These research efforts involved extensive energy simulations and analysis, along with edits to code language. Mr. Saxena’s extensive experience with daylighting simulation in DOE2 enabled him to lead the analysis in a project funded by EDR (Energy Design Resources) to improve eQuest’s and SkyCalc’s daylighting simulation capabilities. The project was carried out in association with JJ Hirsch and Associates and enhanced daylighting simulation in DOE2.2 and added the capability in eQuest to perform parametric daylighting simulations.

Mr. Saxena was the lead analyst on a landmark project dealing with daylighting and productivity in office buildings funded by PIER (Public Interest Energy Research), which uncovered statistically significant links between people’s productivity at work in offices, and their indoor environment, especially windows and daylight. Mr. Saxena was the project manger for PG&E’s Relocatable Classroom Retrofit Pilot Program which presented a suite of measures to improve energy efficiency, health and productivity in relocatables classrooms. Mr. Saxena was the project manager for a EDR (Energy Design Resources) funded project called the Green Calculator that presents a web-based tool to calculate the energy impacts of measures that are usually employed for benefits other than energy. Mr. Saxena has managed design assistance projects for schools, retail and multi-family projects on improving energy efficiency and has great depth and expertise in whole building energy simulation and analysis.  

Before joining HMG, Mr. Saxena worked as a Research Assistant at Arizona State University under Professor David Tait on a skylight testing project.  This project involved constructing a calorimeter and testing of various types of skylights to determine their solar heat gain coefficient.  Prior to that Mr. Saxena worked as an Assistant Lecturer at the University of Bombay and as as a junior architect at CDCS, a major architectural firm in Mumbai, India. 

Mr. Saxena is an active member of the USGBC Northern California Chapter’s Sacramento Committee. He is also a member of the Society of Building Science Educators. At Arizona State University, Mr. Saxena defended his Masters thesis in “Microclimate Modification: Calculating the Effect of Trees on Air Temperatures in Residential Neighborhoods” in which he has successfully developed a computer based tool for predicting changes to air temperature due to evapotranspiration from trees, and their effect on the energy use of residential buildings. He has presented papers on this and previous works at conferences of ASES (American Solar Energy Society), UIA (Union Internationale d’Architects), and ICHH (International Conference on Humane Habitat). Mr. Saxena holds a M.S. in Building Design with a major in Energy and Climate Responsive Design from Arizona State University. He holds a B.Arch from University of Bombay, India.
