Before
Refurbishment At
the start of 1900, in Florence, a discussion about the necessity of a new
hospital building began and a suitable area was located on the hills around
Careggi. In 1910, the Hospital of Santa Maria Nuova bought the Careggi
estate, to build a subsidiary hospital. The 1912 works to built Villa
Ognissanti started from the first pavilions to admit tuberculosis patients.
The construction went on during 1920s, to finish in 1936. The
Villa Ognissanti complex consists of several buildings located inside a park
and were not in use before the construction of the new Meyer Hospital. The
three pavilions, East, West, and central wing, are oriented East-West axis
and consist of three-storey buildings.
Objectives
of the refurbishment The
main design purposes are to ensure the best possible integration of the
energy, ecology and sustainability aspects into the architectural
retrofitting design of the proposed office building so as to form an
architectural whole, as well as eliminating conflicting strategies and
facilitate proper operation. Moreover,
the project aims to optimise the integration as well as the efficiency of the
energy, sustainability and ecological systems and techniques in the proposed
building in order to achieve the maximum possible energy conservation as well
as the best possible indoor environmental quality together with the adoption
of the more sustainable options. Refurbishment
strategy Fabric improvements Prior to refurbishment, the building had composite, masonry
external walls made from traditional stonework and tile, with U-value over 3
W/m2 K. After refurbishment, insulation was added to the roof, reducing
the U-value from 5.5 W/m2K to 0.427 W/m2K and to the
walls, reducing the U-value to 2.098 W/m2K. The insulating panels
are made from natural materials that do not contain additives and adhesives.
Windows and doors were weather stripped to reduce infiltration. Solar Gain Control and Glazing All windows were replaced with double glazed panels, with UV
film applied to reduce the glare effect on the work stations. External
Venetian blinds were used to control incoming solar glare whilst preserving
the appearance of the building. Lighting Energy efficient lighting with daylight compensation features
was specified. Heating and cooling A new heating system was installed, consisting of 2 condensation
boilers, 1 high efficiency boiler and 2 electrical chillers for space heating
and cooling, plus 1 electrical chiller to produce domestic hot water. A
greenhouse was constructed in front of the central pavilion, to host the main
reception and some administrative offices. This was designed to reduce energy
consumption for heating during the winter by acting as a buffer space, to
minimize heat losses, and also increases natural ventilation through a stack
effect, reducing cooling demand and energy costs. A HVAC plant equipped with
a heat recovery system was installed.
Meyer Hospital greenhouse Ventilation Ventilation is predominantly through a new mechanical
ventilation system, with fresh air delivered through air treatment units. The
system is set to cool and dehumidify at 22oC, this is dictated by
national standards for ventilation in hospital offices. Trickle vents have been specified on windows to allow
infiltration. External louver shutters provide solar shading. Innovative
technologies
The Completed Building
CO2 impact of Meyer Hospital The Meyer Hospital building now has high user satisfaction. The
occupants identify with the building, and enjoy the fact that they are in a
traditional building (with all the attractive advantages of high thermal
mass, many windows, etc) which has modern features. The improved air quality
seems to have stimulated employee productivity. The greenhouse generates good
PR for visitors arriving at buildings, since it is the first thing they see.
It is also beneficial in providing extra heat for offices facing it. However,
it does reduce daylight to these offices and will be the probable cause of
overheating in some offices during warm weather. The night ventilation system has worked well for this building.
During summer in Florence, there is generally little wind, therefore natural
ventilation would not have been as successful in this environment. The night
ventilation proves an acceptable compromise and reduces the load on the
daytime mechanical ventilation. Papers and Publications The Meyer Hospital team have carried out a wide range of
activities to generate publicity for the project. An extensive list of
articles has been produced on all aspects of the project, these have been
published in technical journals, topical magazines and in the national press.
They have also set up an Italian version of the REVIVAL website which focuses
on the Meyer Hospital works. Meyer Hospital will host a special event on the
future of healthcare architecture, in the refurbished office area, as part of
the 28th International Public Health seminar, to be held in
Florence from 22nd-26th June 2008. · World Renewable Energy Congress IX and Exhibition, Florence
