The instructor uses a live example to illustrate: Equivalent levels of occupant thermal comfort and compliance with PMV + elevated air speed analysis from ASHRAE 55-2010.I was wondering why IES is not popular, only because its price I think you can simulate energy consumption and ventilation with the same.Test Example 2: HVAC System for US Federal Office Building.9 3.1. 2.3.This one hour long session covers the steps required in the VE for compliance with Performance Rating Method (PRM) and Energy Cost Budget (ECB) methods of ASHRAE 90.1-2013. IES.Introduction.3 Test Example 1: HVAC System for US Federal Office Building.4 2.1. Which includes metrics for energy, cost, carbon & peak demands.

Option 1: Constant Volume HVAC System. Is at its initial stage and designers may. Slightly time-consuming for only load calculation especially when a design. I personally believe it is. However, 3D model building is its very first step. Initial load calculation all the way to in-depth energy analysis.

LifeCycle is part of the VE/Cost product group and it enables users to undertake Life Cycle Analysis (LCA) studies. Introduction LifeCycle is a module in the IES system. 14Purpose: For this project, the research team will provide the first causal evidence on the efficacy and cost-effectiveness of Virtual Enterprises (VE).References. 9 Option 2: Alternative Energy Saving Design. 8 Option 1: Base Case вЂ“ Conventional Design.

The accuracy of the LifeCycle algorithms is demonstrated. This document serves two functions: 1. In the following pages several LCA calculations published by the US Department of Energy are entered into LifeCycle and the results compared.

In this first example two options are considered. Test Example 1: HVAC System for US Federal Office Building This example is taken from the Life-Cycle Costing Manual published by the US Department of Energy. This should help users better understand the facilities available in LifeCycle.2.

From the current tables provided by the DOE the sum of these annual values over 20 years is 15.13. The electrical discount rate is based upon the electrical price escalation rates projected by the US DOE. Residual Value: $3,500 at the end of the study period (20 years).We then need to decide the best category or вЂtabвЂ™ in LifeCycle to place each of these costs.Description Set the study period to 20 years and the discount rate to 3%. Fan Replacement: $12,000 at the end of Year 12.

Fan replacement of $12,000 in Year 12. Set all other values to zero and LifeCycle will calculate electricity cost of $20,000. Lighting and enter 250,000 kWh with a COSP of 1.0. Use one of the electricity components e.g.

Option 2: Alternative Energy Saving Design The alternative is a constant air volume system with a reciprocal chiller, nighttime setback for heating and air conditioning, and economiser cycle. None.The published LCA results as follows:The differences are insignificant as they are rounding errors created because the discount factors used in the FEMP calculation are from tables rounded to the third significant figure whereas in LifeCycle they are more вЂaccuratelyвЂ™ calculated.2.2. In LCA expenditures are positive and income is negative. This is a negative value as it is an income.

Initial Investment of $110,000. LifeCycle Category Rates Capital EnergyDescription As Case 1 the study period is 20 years, the discount rate is 3% and the electrical discount rate is 2.82%. Residual Value: $3,700 at the end of the study period (20 years).We then need to decide the best category or вЂtabвЂ™ in LifeCycle to place each of these costs. Fan Replacement: $12,500 at the end of Year 12. Operating, Maintenance and Repair: $8,000 Annual cost. Electricity: $13,000 per annum (162,500 kWh at $0.08/kWh).

None.The published LCA results for Option 2 are:The differences due to rounding errors created in the FEMP calculation.2.3. Residual Value of -$3,700 in Year 20. Fan replacement of $12,500 in Year 12. LifeCycle calculated electricity cost of $13,000. All other values were set at zero. The lighting electricity component was given 162,500 kWh with a COSP of 1.0.

However, the problem has been made more complex due to the following changes: п‚·The initial costs of the HVAC system will be phased in over an initial two year period. The basic information is the same as Test Example 1. Test Example 2: HVAC System for US Federal Office Building This example is taken from the Life-Cycle Costing Manual published by the US DOE. Remember this is over and above the 3% rate of return already taken into account through the discount rate.3. In this case, from LifeCycle: п‚· п‚·Option 1 is $516,183 Option 2 is $432,404Hence Option 2 provides a Net Saving of $83,779 over twenty years.

Both systems use electrical and natural gas.3.1. This will result in a higher residual value of $20,000 at the end of the 20-year service period. The replacement cost of the base system after 15 years will be $60,000 to prolong its life to at least 20 years. The useful life of both systems is different: 15 years for the base case and 20 years for the alternative. Two years pre-service followed by a 20 year service period.

Fuel: 1700 GJ at $5.93/GJ per annum. Electricity: 125,000 kWh at $0.08/kWh per annum. The relevant cash flows are as follows: п‚· п‚· п‚· п‚· п‚· п‚· п‚·Initial Investment: $103,000 over two years pre-service.

The electrical discount rate, based upon the electrical price escalation rates projected by the US DOE is normalised in LifeCycle to be 2.82%. Year 22.These costs are then entered into the following LifeCycle categories: LifeCycle Category RatesDescription Set the study period to 22 years and the discount rate to 3%. Residual Value: $20,000 at the end of the study period i.e. Plant Replacement: $60,000 at the end of Year 17 i.e. Fan Replacement: $12,000 at the end of Year 14 of study, i.e.

Therefore to incorporate this information, go to the Fuel option in Energy and enter 5.93 into the rate and 1700 in the Fuel and set the COSP at 1.0 (because these figures are fuel consumption and system efficiency is already incorporated). However, fuel is 1700 GJ at $5.93/GJ per annum. Electricity: 125,000 kWh at $0.08/kWh per annum entered as before. We could also have entered these costs via the вЂOtherвЂ™ category in LifeCycle. The capital costs have now been assigned to вЂRepairвЂ™ costs in Years 1 and 2.

Residual Value of -$20,000 in Year 22. Plant Replacement of $60,000 in Year 17. Fan replacement of $12,000 in Year 14. Second instalment of plant: $51,500 in Year 2.

Fuel: 1180 GJ at $5.93/GJ per annum. Electricity: 100,000 kWh at $0.08/kWh per annum. The relevant cash flows are as follows: п‚· п‚· п‚· п‚· п‚· п‚·Initial Investment: $110,000 over two years pre-service. Option 2: Alternative Energy Saving Design The alternative is similar to Option 2 of Test Example 1. With this option we can define these costs between Year 3 and Year 22.The differences are due to rounding errors in the discount factors used in the FEMP calculation.3.2.

Residual Value: $3,700 at the end of the study period i.e. Fan Replacement: $12,500 at the end of Year 14 of study, i.e.
