3Energy Legislation
- Federal- 10 CFR 436A (Federal Energy Mngmt)-
Exec. Order 13423 - Delaware State- Title 29, Chapter 69 (Energy
Star and life cycle costing)- Exec. Orders 31
and 82
4New Governor Jack Markell- Quotes
- - We ought to install photovoltaic solar panels
and technologies on the roofs of state buildings,
prisons and the like and generate electricity.
- Offer energy efficiency tax incentives that
reward investments in energy efficiency by
consumers or businesses.such as efficient
heating or air conditioning systems, windows or
insulation, solar electrical and hot water
heating, and geothermal heating and cooling.-
We should explore the possibility of installing
wind turbines on larger state parcels of land and
prisons.- Our state must catch up and upgrade
the state building codes, ensuring that Delaware
architects and builders incorporate higher levels
of energy efficiency into homes and commercial
buildings.- Ensure that construction policies
and requests for proposals for all public
buildings incorporate energy efficiency and
sustainable design.- Delaware state
government should lead by example when it comes
to renewable energy.

6Code for Energy Conservation
- International Energy Conservation Code 2000 for
residential - IECC 2001 supplement for all other buildings
- - ASHRAE/IESNA Standard 90.1- 1999
- Delaware Energy Office- certification of
compliance with 90.1 or COMcheck-EZ
7Purchase of Energy Star Products
- Energy Star products required to be used in all
State procurement - - unless not available competitively
- - not available in reasonable time
- - product doesnt meet performance
- Public Works- A/E must include Energy Star in
specifications - Can have alternate for non-Energy Star to perform
lifecycle costing - Required use of Energy Star equipment unless
agency can demonstrate in writing to OMB why it
cant meet requirement
8Life Cycle Costing (Title 29, Chapter 69 DE State
Code)
- Public works- Project Architect or Engineer
required to use lifecycle cost analysis - - equipment, systems, material, design
- Reduced operating, maintenance, or energy costs
over the useful life - Specifications for equipment with the lowest
total cost of ownership
9Life Cycle Cost Analysis
- Considers all facility costs from owning,
operating, maintaining and disposal - Used to determine most cost-effective alternative
- NOT the same as PAYBACK- payback looks at time
to recoup initial investment - Time value of money
10Life Cycle Costing
- Study Period- usually life of the system
- - DE Capital Projects use 20 year bonds
- Discount future amount to present value
- - Initial costs (construction)
- - Recurring costs (maintenance, energy)
- - Dont worry about residual value
- When? Concept to design development (10 to 30
design)
11Life Cycle Cost elements equipment, systems,
materiel and design elements
- Building envelope (walls, roofs, insulation,
windows, glazing) - Mechanical systems and components (heating,
ventilating, air conditioning, plumbing) - Electrical equipment (lighting controls, motors,
drives, transformers, power distribution)
12Life Cycle Costing
- LCC is a tool to select systems to meet both the
customers needs and save them money over the
buildings lifetime - Compare system components (higher grade
equipment, drives, renewables) to save energy - First cost vs. total cost of ownership
13 Life Cycle Costing- why?
Big Number!
14LCC Example Amoco Bldg
- 14,225 SF, New Castle (1,150 SF Lab space)
- 20 year period, 3 energy cost inflation, maint.
costs flat - Compared 4 replacement options for an existing 10
ton packaged heat pump new wing- Alt. 1
Replacement in kind- Alt. 2 Dx cooling with gas
heat- Alt. 3 Geothermal heat pump- Alt. 4 Dx
cooling, gas heat w/ energy recovery - Used Trane Trace 700 software
- Also studied boiler replacement and cooling
system replacement for entire building
15LCC Example Amoco Bldg
- East wing resultsAlt 2- 1.4 year simple
paybackAlt 3- 42 year Alt 4-
3.5 year - Main building best option LCC dual condensing
boilers and air-cooled chiller (5.6 year simple
payback over replacement in kind)
16Life Cycle Cost Software
- FEMP BLCC version 5.3, PC only, free
- Free excel spreadsheets
- Commercial- Trane Trace 700- McQuay System
Analyzer- HAP (hourly analysis program)
Carrier- ABB Fan Save and Pump Save
