27、eir personal environment,including bedside control of lighting and window shades, can improve patients psycho-logical outlooks, rates of healing, and quality of stay. According to the American Society of Healthcare Engineers (ASHE), the health ofpatients, staff, and visitors can be profoundly affect
28、ed by the quality of the indoor air. Arecent study2completed by the Lawrence Berkeley National Laboratory (LBNL)reported that improvements to indoor environment could reduce healthcare costs andwork losses from communicable respiratory disease by 9% to 20%. Advanced, energy-efficient heating and coo
29、ling systems can also create cleaner, healthier indoor environ-ments that reduce the threat of infection for both patients and staff. Advanced energy-efficient systems can also be much quieter than previous technol-ogy. This produces quieter, more comfortable, and more productive spaces. This alltra
30、nslates to better patient outcomes, shorter patient stays, reduced sick-days for health-care staff, and lower overall costs.ATTRACT PATIENTS AND BETTER RECRUIT/RETAIN THE BEST DOCTORS AND SKILLED NURSESA growing advantage of energy-efficient, sustainable healthcare facilities is marketdifferentiatio
31、n. More and more hospitals are demonstrating their commitment to theirlocal community and the global environment while enhancing their bottom-line perfor-mance. An enhanced patient experience translates to improved satisfaction survey results.There is no better promotion for a hospital than the reco
32、mmendation of satisfied patientsand families where the facility and service exceeded their expectations. And the abilityto recruit and retain the best and brightest doctors and skilled nurses will be improvedby providing an efficient, comfortable, clean, and healthy place to work and treatpatients.
33、Improving these attributes will help the physicians, nurses, and staff to deliverhigh-quality care.LOWER CONSTRUCTION COSTS/FASTER PAYBACKThoughtfully designed, energy-efficient hospitals can cost less to build than typicalhospitals. For example, optimizing the envelope to match the climate can subs

LBNL Report, Lawrence Berkeley National Laboratory, Berkeley, CA.FOREWORD XVIIwill have lower mechanical costs than the one withoutand will cost less to build. Ingeneral, an energy-efficien
36、t hospital requires less heating, costs less to maintain, has less expensive installation, requires fewer lighting fixtures due to more efficient lighting, allows for downsized heating systems due to better insulation and windows, and allows for downsized cooling systems with a properly designed day
37、lighting systemand a better envelope.Some strategies may cost more up front, but the energy they save means they oftenpay for themselves within a few years. REDUCED OPERATING COSTS According to the most recent Commercial Buildings Energy Consumption Survey(CBECS)1conducted by the Energy Information
38、Administration (EIA), the average hos-pital in North America consumes nearly 250% more energy than the average commercialbuilding. By using energy efficiently and lowering a hospitals energy bills, hundreds ofthousands of dollars can be redirected each year into upgrading existing facilities, care-g
39、ivers salaries, and investing in the latest technology in medical equipment.Strategic up-front investments in energy efficiency provide significant long-termsavings. In the financial performance of the hospital, every dollar saved in energy andoperating costs is equal to generating $20 growth in new
40、 top line revenues. In an average hospital, lighting uses a large portion of the overall energy budget.Therefore the design should include an energy-efficient lighting design and efficientlighting fixtures but also should evaluate opportunities for dimming controls and multi-level switching systems.
41、 In the many areas where the design team brings quality day-light into the space, lighting controls can be used to regulate the output of electric lightsto optimize the quality of the visual environment while saving significant amounts ofenergy. The smart use of a sites climatic resources and more e
42、fficient envelope design arekeys to reducing a buildings overall energy requirements. Efficient equipment andenergy management programs then help meet those requirements more cost-effectively. Because of growing water demand and shrinking aquifers, the price of water isescalating in many areas. Savi
43、ng water can thus save money but also can generally saveenergy. Lower operating costs mean less fluctuation in budgets because of price instabilitiesof energy. Purchasing energy efficiency is buying into energy futures at a known fixedcost. REDUCED GREENHOUSE GAS EMMISSIONS BENEFIT THE COMMUNITY Acc
44、ording to some estimates, buildings are responsible for nearly 40% of all carbondioxide emissions annually in the United States. Carbon dioxide, which is producedwhen fossil fuel is burned, is the primary contributor to greenhouse gas emissions.Healthcare facilities can be a part of the solution whe
45、n they reduce their consumption offossil fuels for heating, cooling, and electricity. The local community, patients, and staffwill appreciate such forward-thinking leadership.1.

46、ineers, Inc., 2007).1The Advanced Energy Design Guide for Small Hospitals and Healthcare Facili-ties (AEDG-SHC; the Guide) is intended to provide a simple approach for contractorsand designers who create small to medium size acute care, outpatient and inpatientbuildings, up to 90,000 ft2. Applicatio
47、n of the recommendations in the Guide shouldresult in small healthcare facilities with 30% energy savings when compared to thosesame facilities designed to the minimum requirements of ANSI/ASHRAE/IESNA Stan-dard 90.1-1999. This document contains recommendations and is not a minimum code orstandard.
48、It is intended to be used in addition to existing codes and standards and is notintended to circumvent them. This Guide represents a way, but not the only way, to buildenergy-efficient small healthcare buildings that use significantly less energy than thosebuilt to minimum code requirements. The rec
49、ommendations in this Guide provide bene-fits for the owner while maintaining quality and functionality of the space.The mission of a healthcare facility is to facilitate the care and treatment of peopleof varying stages of disease or disability. The performance requirements of a buildingintended to serve these needs will be the driving force behind most design decisions forthe building, and the benefits
