6. Outside Air Requirements Stnd 62 Well it all starts by determining how much outside air you require. This should be available through your local code authority, or else by referencing your international mechanical code, or ASHRAE. As you can see by the chart, we have been recommending ventilation rates for over 50 years, and rates have moved up and down over time. Currently ASHRAE standard 62 provides guidance for acceptable air quality, as is considered as a minimum recommendation. As you can see back in 1981, there was a significant reduction in outside air requirements, due to the energy crisis we had in the 70�s. In the 80s and early 90�s we built tighter buildings to reduce energy loads, and at the same time, brought less outside air into out buildings � no wonder we have indoor air quality problems today. ASHRAE has proposed changes to the International Code Council's (ICC) International Energy Conservation Code (IECC) and International Mechanical Code (IMC). The proposed changes are scheduled to be evaluated in September 2006 for possible inclusion in the 2007 supplements. Use of ASHRAE Standard 62.1 in IMC Would Provide Lower Costs Use of ASHRAE's new ventilation rate procedure in the International Mechanical Code (IMC) would reduce first costs and energy costs in many buildings. ASHRAE has proposed that the ventilation rate calculation procedures from ANSI/ASHRAE Standard 62.1-2004, Ventilation for Acceptable Indoor Air Quality, be adopted into the IMC. The code establishes minimum regulations for mechanical systems using prescriptive and performance-related provisions. The current ventilation criteria in the IMC are based on ASHRAE Standard 62-1989. Through research and experience, information on indoor air quality and ventilation has evolved. In response, ASHRAE has enhanced its standard to include the new rate procedure. This code change would make the IMC consistent with the standard and the 2006 Uniform Mechanical Code.Well it all starts by determining how much outside air you require.

15. USGBC & LEED � Leadership in Energy & Environmental Design� LEED provides a definition for �green buildings� It is a market-based standard to distinguish and promote sustainability It is a tool to introduce, promote and guide comprehensive and integrated building design The LEED green building rating system is a voluntary, consensus based, market driven, and building rating system based on existing proven technology.

16. Transforming the MarketBetter Buildings = Better Performance

17. LEED� Certification Points Building Rating system is based upon the following points system: Certified 26 to 32 Silver 33 to 38 Gold 39 to 51 Platinum More than 51 There are 69 points available. It is impossible to receive all 69 points on a project as some points work against others. There are overlaps of some points, and other points are influenced by the type of construction, existing building or new construction.

18. LEED� PointsWhere Energy Recovery Helps In Earning Points Point Categories Sustainable Sites 14 Water Efficiency 5 Energy and Atmosphere 17 Materials and Resources 13 Indoor Environmental Quality 15 Innovation & Design Process 5 Points are not simply awarded for purchasing energy recovery equipment. The points that may be awarded can be affected by purchasing energy recovery equipment. Sustainable Sites and Water Efficiency have no points influenced with the addition of energy recovery.

Sustainable Sites and Water Efficiency have no points influenced with the addition of energy recovery.

19. Energy and AtmosphereOptimize Energy Performance After reaching the minimum energy requirements established by ASHRAE Standards 90.1 while achieving ZERO use of CFC-based refrigerants, LEED points may be obtained by reducing the building�s energy consumption.

20. Energy and AtmosphereMeasurement & Verification To obtain points, equipment performance must be verified. Large claims in energy savings must be proven. Example: 50% Energy Savings = 8 LEED Points ARI Certified Products = Proven Performance=Accepted Proof Demand The ARI Standard 1060 Certification Label This credit is not affected directly by the use of energy recovery equipment but is affected by the performance of the equipment. The engineers must have confidence that all equipment will perform as specified For example if the LEED design team is using energy recovery equipment to establish a 50% reduction in energy consumption and thus obtain 8 points, they will want assurance that the equipment will work as predicted. The measurement and verification calls for each peace of equipment to be checked to see that the performance was per the specification. One good way to make sure that the equipment will perform is to only accept equipment that has its performance certified by an outside agency such as ARI. In the case of the energy recovery equipment this would be to only accept ARI 1060 certified equipment or components.

26. Applying ERV technology into your designs How do I select the right technology ? How do I ensure I am getting the energy savings? How can I be confident that I am giving my customer the calculated savings? How can I compare performance with various technologies? How I compare one technology to another?

27. Selecting the Right Technology Consider the application Source control or dilution control? If source control, EATR is important Geographic location Demands for dehumidifying outdoor air in summer? Need for frost control in winter? Conditioned space requirements How is outside air introduced into the system? Humidification in winter? Conditioning space for summer? How am I am managing �free cooling� opportunities What technologies are you comfortable with, or are your customers demanding?
