Energy-efficient HVAC design is a fundamental of green building, for good reason:
The scale of the issue: HVAC is responsible for more than a third of energy use in commercial buildings in the U.S.
The scale of returns: Smart designs can easily save upwards of 40% of that energy, often with strategies that offer instant or short “payback.”
The human impact: Discomfort from spaces that are too hot or too cold, and lack of adequate ventilation, are an epidemic. Good design that fixes these problems supports healthier, more productive occupants.
Don’t make the all-too-common mistake of thinking of HVAC design separately from building envelope design. Over-glazed buildings lead to oversized mechanical systems, increasing costs on both fronts. A tight, well-insulated envelope may cost a bit more but can pay for itself with less mechanical equipment.
For a lot of people, computer modeling is synonymous with energy modeling, and climate data is something you just input to your energy model. Kjell Anderson wants you to do energy modeling for your buildings, and he wants you to do it early—as BuildingGreen has advocated—not just for "keeping score" at the end. In this webcast, Anderson will demonstrate tools that are so easy that they can be used on every project regardless of budget or sustainability objectives, typically taking 3 to 5 hours once you have your system down—and almost no time for projects in a city where you have already done an analysis.
