  6. EML 4601 LECTURE 1 The HVAC Business In 1999 in the US: 181 x 109 sq.ft. residential space 60 x 109 sq. ft. commercial space Total value of building stock is approximately $20 x 1012 (GNP IS 1990’s was $5 x 1012) H. A.. . Ingley PhD,PE

  7. EML 4601 LECTURE 1 The HVAC Business The value of Mechanical, electrical and mechanical systems supporting this stock would be approximately $5 x 1012 H. A.. . Ingley PhD,PE

  8. EML 4601 LECTURE 1 The HVAC Business The value of Mechanical, electrical and mechanical systems supporting this stock would be approximately $5 x 1012 Renovations of this stock amount to approximately 2% per year or $100 x 109 per year H. A.. . Ingley PhD,PE

  9. EML 4601 LECTURE 1 The HVAC Business Renovations of MEP systems of $10 x 1010 per year generate about $8x109 in design fees annually (assumes an average fee of 8% of the construction value). Abbott, Langer & Associates, Inc. Salary and Benefits Survey Reports H. A.. . Ingley PhD,PE

  10. EML 4601 LECTURE 1 The HVAC Business Commercial building stock increases approximately 2.5% per year. This is equivalent to about $15 x 1010 per year in new commercial construction. This work would generate MEP fees of approximately $6.75 x 109 per year. H. A.. . Ingley PhD,PE

  11. EML 4601 LECTURE 1 The HVAC Business A typical MEP firm of approximately 20 – 30 people would bill about $2.5 x 106 per year. The $6.75 x 109 per year in fees would support approximately 2700 firms of this size (or about 50 firms of this size per state if equally distributed) There are 5000 professional engineering firms in Florida. H. A.. . Ingley PhD,PE

  12. EML 4601 LECTURE 1 The HVAC Business HVAC managers in general have a BSME degree and will be making about $115,000 per year on the average. Project managers will be making about $65-70,000 per year. Some owners report making over $1,000,000 per year. H. A.. . Ingley PhD,PE

  13. EML 4601 LECTURE 1 The HVAC Business Another impact of the HVAC industry is related to energy use. U.S. spends 500 billion dollars annually on energy. The annual cost of energy use for most buildings averages about $2.50/sq ft. Building energy use is approximately 38% of all energy use in the US. H. A.. . Ingley PhD,PE

  14. EML 4601 LECTURE 1 Oakland University Annual Energy Report Fiscal Year 2005 Submitted, August 23, 2005 by James Leidel Energy Manager H. A.. . Ingley PhD,PE

  15. EML 4601 LECTURE 1 The HVAC Business Of the total energy use for a building: 17% is for heating 7.2% for cooling 3.8% for refrigeration 3.5% for ventilation. H. A.. . Ingley PhD,PE

  16. EML 4601 LECTURE 1 So what does an HVAC engineer do? Generally in a MEP firm, the mechanical engineer who is working specifically on HVAC (not plumbing or fire protection) is in responsible charge of the design and specification of equipment and systems that heat, cool and ventilate the building. H. A.. . Ingley PhD,PE

  17. EML 4601 LECTURE 1 The HVAC Engineer Some of the commons tasks are: Program development System selection Preparing drawings Preparing specifications Cost estimating Bidding Field investigations H. A.. . Ingley PhD,PE
