4 Learning Objectives 1. What is Net Zero? 2. Why are Net Zero Energy Buildings Important? 3. The path to net zero? 1. Building Envelope 2. HVAC 3. Water Heating 4. Electric Loads 5. Renewables

5 What is a Net Zero Energy Building? On an annual basis, is a building producing enough energy from on-site renewables to off-set the amount of energy it uses from the energy grid. According to the DOE, A Common Definition for Zero Energy Buildings, which states that a Zero Energy Building is an energy-efficient building where, on a source energy basis, the actual annual delivered energy is less than or equal to the on-site renewable exported energy.

11 The use of fossil fuel energy to support our every day life, has a direct has a direct impact on the amount of carbon dioxide (CO2) emitted into our environment, which is having a direct effect on global climate change. Buildings are the largest contributor of CO2 emissions into the environment. We have a responsibility to reduce carbon emissions in the built environment and in our own lives. Source:

15 Paving the way to Net Zero Energy Buildings Advocate for and support programs/policy that create a sustainable future. Set a goal of Net Zero Energy on your building project. Hire a Great Team. Collaborate, Iterate, Communicate. Building Performance Modeling, Quality Control Checks, Measure Performance.

Mechanical Systems Heating, Cooling, Ventilation, Energy Recovery Water Heating Electric loads 3. Passive Elements Window shading Roof orientation Thermal Mass 4. Renewable Energy Roof top Ground mount How to get to Net Zero Energy Buildings Reduce Energy Consumption First!

17 Integrated Design Process

18 BUILDING ENVELOPE (Walls, Roof, Slab) 1. Focus on the building enclosure. - Collaborate on details with design and construction team. - Good notes on drawings and specifications. 2. Air-Tight Construction All Walls, Ceilings, Penetrations fully sealed. All materials, details, and techniques understood. Pre-testing and troubleshooting. Blower-Door Test

19 3. Minimize or Eliminate Thermal Bridge s: A building element that bridges temperature from outside to inside by penetrating the building envelope. BUILDING ENVELOPE (Wall, Roof, Slab)

20 MECHANICAL SYSTEMS (HVAC) 1. Properly Sized Mechanical Systems. 2. Continuous and balanced Ventilation with Energy Recovery 3. Installation Quality / Commissioning 4. Smart Controls

21 WATER HEATING

22 Lighting LED Smart Controls (Daylight sensor, Occupancy Sensors) Appliances Energy Star Rated Plug Loads Ability to shut-down. Elevators, Conveyors. Energy saving strategies ELECTRIC LOADS

23 Site orientation and building layout Passive heating and cooling through natural ventilation and solar heat gain. Shading of windows in summer Thermal Mass PASSIVE ELEMENTS Taking advantage of free heating and cooling

24 RENEWABLE ENERGY 1.Reduce Energy Consumption First 2. Prepare for future Renewable Energy Solar Ready Buildings 3. Produce Renewable Energy Onsite (Roof top or ground mounted)
