HVAC Systems for an Energy-Positive Building
Too often the natural building world creates a great building with a decent mechanical system. We need to have the tools to get it right every time: every building making more energy than it consumes. In this presentation and discussion, we will review options to help hit that target. We will discuss technologies like pushing passive solar design further, radiant cooling and heating, air-source heat pumps: there are a lot of options here– VRF/mini-split/multi-split– what do those systems mean? How are they different? What are the pros and cons of all these ideas? Let’s get down the nitty-gritty of how to use less energy.
Relevance: Natural Building and low energy go hand in hand. We need to keep pushing for more efficient –and more affordable– HVAC systems. I look forward to sharing experience from designing hundreds of systems with this group.
J. August Hasz P.E., President and Principal Engineer for Resource Engineering Group. August has overall responsibility for the day-to-day operation of the company, oversight of all scopes of work REG provides and detailed engineering including mechanical system design, structural systems, energy auditing, commissioning for new and existing buildings, building simulation, and solar energy analysis. August’s engineering mastery, creative attitude, and an innate sense for completing complex projects on time and budget have allowed him to compile an impressive track record of successful projects at REG over the course of two decades. His project experience includes: two Net Zero Energy affordable housing neighborhoods, a long list of Community Rebuilds projects, passive heating and cooling strategies, active solar thermal and solar electric systems, ground source heat pumps, and radiant cooling systems. His past experience includes fundamental research into glass and ceramic materials, water pump design, and water and wastewater plant operation.
August has presented at the International Strawbale Association conference, Colorado AIA chapter annual meeting, Solar Energy International courses, and Western Colorado University. He has also earned a Bachelor of Science degree in Glass Engineering Science from the New York State College of Ceramics at Alfred University, with honors. He is LEED accredited, NCEES registered, and a member of ASHRAE. He is a licensed Professional Engineer in Colorado, California, Massachusetts, Montana, New York, New Jersey, Texas, Utah, Vermont, and Wyoming.
