Ground Broken on $146 Million Hospital in New York’s Finger Lake Region

CORNING, N.Y. — The groundbreaking was held April 18 for the new $146 million Guthrie Corning Hospital, with construction on the 232,000-square-foot facility scheduled to begin in late June.

The hospital features 65 private rooms and is designed to be energy efficient and promote green operations. The new hospital will replace the outdated Denison Parkway facility, built in the early 1900s.

“This project truly represents a new era in patient care for the residents of the region,” said Shirley Magana, president of the Hospital.

When open in summer of 2014, patients will benefit from an integrated campus designed for efficient delivery of quality care and increased outpatient services, according to officials.

The Guthrie Cancer Center Corning location will be on the first floor of the new hospital with a separate entrance for patients. The campus will also include an efficient emergency department with 18 treatment areas and an on-site helipad to quickly facilitate trauma patients or transfers.

Gilbane-Welliver is responsible for pre-construction and construction management services for the new hospital.

Hammes Co. will serve as the owner representative for the project with Gould Turner Group serving as the designer. Smith Seckman Reid Inc. (SSR), with Hunt Architecture, engineering and land surveyors, as the civil engineer, are responsible for the MEP engineering.

Lighting Controls Provide Green Benefits

It’s no secret that replacing existing lights with more energy-efficient lighting sources, such as LED, is one of the easiest ways to reduce energy use.

Lighting in commercial buildings can account for up to 40 percent of total energy cost, but what most people don’t realize is that making the lighting source efficient is only half the story — an even greater level of energy reduction can come from improving lighting control.

Lighting control systems, based on a variety of technologies, have been proven to reduce lighting energy consumption in commercial and industrial buildings by up to 70 percent. These solutions can automatically turn off lights when they are not needed, optimize light levels to suit worker needs, reduce overall demand for lighting energy, and provide facility managers with system-wide lighting management.

Although the core concepts behind lighting control aren’t new, a set of advanced wireless technologies are bringing them more mainstream, providing ways to expand capabilities to a wider set of customers.

Advanced Lighting Controls

Today’s advanced lighting control systems create a large-scale lighting network that delivers the correct amount of light, where you want it, when you want it. Lights can automatically switch or dim at set times or under set conditions; facilities managers can make changes to lighting when appropriate or to meet financial incentives; and users can have control over their own lighting levels to provide optimal working conditions.

Customers of lighting control systems often apply a set of lighting control strategies or applications, each of which uses a specific technology and method to control a subset of lighting usage. These strategies include occupancy sensing, daylighting, scheduling, task tuning and more.

Lighting control systems typically include some or all of the following:

• On/off and dimming controls

• Occupancy sensors to detect whether rooms are occupied

• Photosensors to detect the current illumination levels provided by natural and/or artificial light

• Scheduling that turns on, off, and dims luminaires at preset times

• A centralized control system interface (such as a wall panel or computer software) to manage all of the above

• A method of communication between the lighting equipment and control system

• A method of measuring, displaying, and responding to lighting energy usage

Emerging applications

In older lighting designs, each group of luminaires and lighting devices was installed in a closed loop and a facility manager could only access the lighting by physically accessing each room. Some of today’s lighting control systems change this equation by linking together the control of an entire building — and even separate buildings — to remotely manage and control light settings. This way, each light and device within a lighting control system can be individually addressable, creating a truly intelligent lighting network. This vastly improves ongoing management cost and complexity, and provides the capability for facility managers to reduce energy use in ways that were never before possible.

New areas of savings are also being created in advanced lighting control systems by making energy usage data readily available for facility managers. Better data often equals better savings, and as managers gain access to real-time and historical information about the usage of energy by light, room, zone and building, they have the information for more effective decision-making. Also, some lighting control systems can tie into utility demand management programs, allowing buildings to automatically reduce lighting use at peak times in order to gain financial incentives.

Further benefits of advanced applications can include tax incentives, enhanced compliance with LEED and other building codes, and interoperability with an ever-expanding network of in-building smart wireless devices, such as plugloads, blinds, thermostats and more.

Removing the Wires

Within these advanced systems, the introduction of innovative wireless controls is further reducing costs and complexity while easing implementation. Wireless lighting control systems utilize wireless technology (similar to the wireless networks you may use to access the Internet at work or home) to communicate commands between lighting devices — sensors, switches, and the ballasts or LED drivers connected to lights.

While traditional lighting control systems utilize a controller that is hard-wired to each device (often with miles of copper wiring), a wireless system uses a controller with an antenna that manages communications between devices. Facility managers and individual users can utilize a software interface to manage the system and change settings, which are then routed through a controller to the individual lights. The result is a flexible, scalable system that is easy to commission, especially in retrofit scenarios where existing building infrastructure often gets in the way of installing a new lighting control system.

Lighting Controls & Green Buildings

Lighting is one of the largest sources of energy use on the planet, and yet only about 7 percent of commercial buildings have installed advanced lighting controls. Although lighting control systems have been shown to provide tremendous benefits, many parts of the commercial building market have been hesitant to utilize these systems in anything but the most basic configurations. This is often due to cost and complexity due to labor, equipment and wiring, and the commissioning, management and upkeep of these systems.

The new generation of systems is eliminating these cost and complexity concerns and increasing system capabilities by removing the dedicated control wiring. Through the use of modern enterprise-class wireless networking technology, system-wide controls strategies can be implemented without significant upgrades or added infrastructure costs.

Concurrently, the smart grid and other building systems have embraced wireless technology and are beginning to reap the rewards. Removing the wires delivers on the promise of lighting control by providing even greater benefits, at a lower cost, and to a much broader set of potential customers.

While net-zero buildings are still a long way off in the United States, intelligent lighting control systems with wireless networking capabilities are readily paving the way in helping companies take simple steps to save money and make our buildings greener.

Sun Control: Daylighting and Efficiency

High-performance window systems are considered by many to be an essential to todays health care facilities. Multiple studies show that patient recovery, occupant morale and staff productivity are positively influenced by improved ventilation, indoor air quality and daylighting.

In addition, window systems can improve energy-savings and safety, reduce maintenance needs and extend the lifecycle of buildings and materials. However, it’s not only hospitals and businesses that are benefitting from these improved windows, many homeowners have already replaced their older windows for new ones. By using local window companies, such as this one dealing with replacement windows austin area, homeowners are able to save on their energy bills, as well as reduce their own condensation inside their homes.

Hospitals are the second largest energy consumer among U.S. buildings, according to the architectural research group at San Francisco-based Anshen+Allen, collaborators on the Green Project Lab, a prototype featured at several national healthcare conferences.

Reviewing and summarizing more than 4,000 reports and surveys, the firm also learned that:

Patients with views and access to nature recover more quickly, experience less pain and require fewer medications than patients with no view to nature.

80 percent of respondents felt that environmentally friendly building materials, energy-conserving light fixtures and increased daylighting are priorities for facilities planning and operations.

90 percent of respondents believe the patient benefits from being able to control their environment including lighting, television and privacy windows.

To helping achieve these benefits, window system components should be part of an integrated design. This design approach not only means working with the owner, occupants, facility manager and architect; but also includes working with the lighting engineer, mechanical engineer and HVAC contractor, landscape architect and interior designer.

As part of these early discussions, specialty contractors and window system manufacturers can provide recommendations to accommodate the project’s unique requirements for successful solar management and natural daylighting. Glass, framing, thermal barriers, and shading devices are essential considerations in high-performance window systems that help control the solar spectrum. Besides, in countries like the UK, homeowners use double and secondary glazing for better window insulation. You can check out online resources like the ones provided by Builder & Engineer to know more about insulated glazing.

Glass Options

The solar spectrum consists of ultraviolet light, visible light, and infrared. UV is invisible to the human eye and long-term exposure damages materials, such as sensitive medical collections. UV also deteriorates plastic, a staple in healthcare facilities, and fades furniture, fixtures and artwork. Visible light also can contribute to fading. Like UV, infrared is invisible to the human eye and has a penetrating heat effect.

Typically, solar reflective glass coatings dramatically reduce unwanted heat gain by reflecting and absorbing high amounts of infrared and visible light. Spectrally selective glass coatings allow color flexibility in reflection and transmission, while blocking a large portion of the solar spectrum.

Unlike static glass with something like 3M Window Film tint on them, electrochromic glass coatings electronically tint to provide dynamic solar control. The Green Patient Lab, version 3.0, uses a high-performance window system with EC glass to demonstrate solar and daylighting control. Strategically positioned within the rooms schematic, the glass reduces glare on the television, while preserving the view to the outdoors.

Healthcare facilities also can strategically optimize glass selection by elevation, using clear substrates and coatings on north-facing faades, and darker glass on south, east and especially west faades. Similarly, darker glass should be considered for large view windows and the use of clearer glass for transom lites. Unless a downward view is important, vision glass below sill height usually can be eliminated, to reduce solar gain that carries no useful daylight.

Pragmatically, floor plan layout should locate rooms with little use for natural daylight, such as washrooms, server rooms, etc., in non-perimeter areas. Activities within a daylit room should be oriented to minimize glare issues, such as facing medical equipment and computer monitors at right angles with incoming sun.

Sunshades

Exterior sunshades intercept unwanted solar heat gain before it can impact a buildings HVAC system load. They also can make a powerful, aesthetic statement in a buildings design, as well as in its performance.

The University of Colorados new Health Sciences Center research complex emphasized ventilation, lab engineering, building operations and maintenance, and energy conservation in its designs.

To assist in accomplishing these goals, the sunshades are engineered as an integral component of the high-performance window and curtainwall systems. These systems incorporate polyamide nylon thermal barriers and nine different glass types in various silk screens and colors. The window spans drench the facilitys interior with natural light, while managing solar heat gain and remaining condensation-free at sub-zero temperatures. The extruded aluminum sun shades on south-facing exposures further enhance performance, while ornamental exterior trim covers add visual interest.

Architects are exercising their creativity with sunshades with blades, tubes, catwalk grids, solid panels and louvers. Louvered sunshades can add diffusion to direct natural daylight for south, east and west facades. At the same time, exterior shelves are limited in their daylight re-directing effectiveness for the diffuse sun of overcast conditions.

Remember, exterior shelves or shades act as solar shading only for high sun angles. For high latitudes or east/west facing facades, cut-off angles can be very low for occupied hours. Below this cut-off angle, supplemental interior shading must be employed to reduce glare from direct beam sun.

Interior Shading

Window blinds also act as effective solar shading, especially when coupled with exterior brise soleil sunshades. Between-glass blinds offer excellent thermal performance, as well as privacy and light control. It may be beneficial for motorized blinds to be used, which can be found from companies such as https://www.smartblinds.org/products/motorised-blinds, to check and see how they can be implemented.

While reducing overall daylight transmission, between-glass blinds significantly improve daylight distribution through the space. Blind slats can be inverted to direct light upwards, if unconventional aesthetics and light leakage in the closed position are acceptable.

Specified as an integral unit, windows with between-glass blinds contribute to safety and sanitation by minimizing the potential dangers of exposed cords and slats, and reducing the need for cleaning and maintenance.

Large, arched windows with between-glass blinds were chosen for The Villages Regional Hospital in central Florida. Located in a popular retirement community, the hospitals patient-friendly atmosphere and stylish design encourages many to equate the facility to that of a hotel. Patients and staff both enjoy the plentiful, natural light. In patient rooms, the between-glass blinds allow individual control of sunlight and views. This sense of control can be an important factor in a patients healing process.

Patients in brightly lit rooms have a shorter length of stay, according to the Center for Health Design. The Centers research also shows patients experienced less perceived stress and pain medication costs were reduced by 20 percent when patients were exposed to increased intensity of sunlight.

Green Goals and Guide

A complete daylighting system shades from direct sunlight, minimizes glare and heat gain, and redirects visible light for deeper illumination. Lighting accounts for 40 percent of the energy used in a typical commercial building.

When properly executed, daylighting can reduce HVAC peak loads with corresponding reductions in mechanical equipment capacity and carbon footprint.

In April 2009, the U.S. Department of Energy launched the Hospital Energy Alliance to reduce energy consumption and greenhouse gas emissions. Furthermore, the new 2010 ASHRAE 90.1 Energy Standard will require a 20 percent to 30 percent increase in energy savings above the current standard.

Healthcare facilities look to green building guidelines for potential energy savings and improved safety and health. The most successful facilities accomplish their green design goals using a whole building approach, taking into account building envelope, site, orientation, HVAC and lighting systems. The Green Guide for Health Care addresses all of these aspects and was the foundation for the U.S. Green Building Councils LEED for Healthcare.

Currently a pilot program, LEED for Healthcare awards a maximum of four points for views and daylight. Separate requirements are given for diagnostic and treatment areas versus in-patient units. In general, these requirements are consistent with those for LEED for New Construction and Major Renovations Indoor Environmental Quality category.

Checklist for Success

Solar control and daylighting systems are best-suited for healthcare facilities under these conditions:

The building team members are brought together early for an integrated design.

The facility will be constructed on an unobstructed site in mid-latitudes with a clear climate.

Whole-building energy modeling is planned.

The design features expansive north- and south-facing faades.

Atria, courtyards, light wells or high ceilings will be incorporated.

Dimmable artificial lighting controls are available for critical spaces.

Task area illumination will be provided.

Blinds, drapes or shades can be used for glare control.
