About the Book

In an era of rising energy costs and tightening environmental regulations, Retrofitting for Energy Conservation by William H. Clark II, P.E., delivers a comprehensive, field-tested roadmap for transforming existing buildings into high-efficiency facilities. Written for engineers, facility managers, and building trades professionals, this authoritative guide bridges the gap between theory and practice—covering every major building system from HVAC and lighting to the building envelope, electrical distribution, and domestic water.

Clark’s approach is grounded in economic accountability: every conservation measure is evaluated for return on investment and simple payback, making the case that energy efficiency is among the most stable, low-risk investments available. The book’s two-part structure first equips readers with core methodologies, then walks them through real-world project implementation and energy auditing techniques. Rounding out the volume are 284 practical energy-saving tips, a glossary, and an introduction to computer-aided numerical analysis. Whether auditing an existing facility or reviewing plans for new construction, this resource remains an indispensable reference for anyone committed to sustainable, cost-effective building performance.

Target Audience

  • Mechanical and electrical engineers (PE-level and early-career)
  • Facility managers and building operations staff
  • Energy auditors and sustainability consultants
  • Architecture and construction professionals
  • Technical/vocational library collections

Key Themes

  • Engineering pragmatism — low-cost, high-impact solutions executable by tradespeople
  • Economic accountability — ROI and simple payback as the core decision framework
  • System interdependence — understanding how changes in lighting, HVAC, and envelope interact
  • Maintenance as efficiency — a well-maintained facility is an energy-efficient one
  • Regulatory and environmental drivers — ozone depletion (Freon phase-out), IAQ standards, and global energy demand

Detailed Table of Contents

Part 1: The Methods

  • Chapter 1 — The Domestic Water System: Covers leak detection, hot water storage temperature optimization, and pipe insulation to reduce thermal loss.
  • Chapter 2 — Building Envelope: Examines the energy impact of walls, windows, and roofs, including load profiling, shading devices, and vapor barriers.
  • Chapter 3 — Ventilation and Infiltration Control: Explores the stack effect, building pressurization strategies, and balancing energy savings with indoor air quality (CO₂ management).
  • Chapter 4 — Lighting Projects I: Introduces high-efficiency lamp technologies (fluorescent, HID) and the fundamentals of color-corrected lighting selection.
  • Chapter 5 — Lighting Projects II: Extends lighting coverage to automated controls such as photocells, occupancy sensors, and daylight harvesting.
  • Chapter 6 — Heating and Cooling Systems: Reviews fan laws, thermostat management, and the comparative efficiency of self-contained HVAC unit types.
  • Chapter 7 — Central Systems: Addresses central plant operations including chiller staging, boiler blowdown, steam trap maintenance, and cooling tower water treatment.
  • Chapter 8 — Electrical Projects: Focuses on distribution losses, motor efficiency, power factor correction, and harmonic impacts from electronic equipment.
  • Chapter 9 — Architectural Concepts: Examines thermal mass, building orientation, below-grade construction, and landscaping as passive energy-reduction strategies.
  • Chapter 10 — Controls: Covers the transition to centralized Energy Management Systems (EMS), optimized start/stop scheduling, and demand-limiting strategies.
