air conditioning and climate control Identify and support the parameters that will meet best practice industry environmental and collections care standards, be cost effective, compliant with workplace health and safety, and reduce current operational costs Identify products (and plants) that best meet gallery and museum professional industry requirements, their specifications, availability, lifecycle, installation requirements and cost implications. -

museum and gallery air conditioning and climate control survey
Most are working to similar set points
Most are spending large portions of their budgets doing it
Consensus seems to exist that there can (and must) be a widening of parameters

air conditioning and climate control
environmental parameters - terminology
set point
seasonal adjustment
rate of change

air conditioning and climate control environmental parameters – adjusting the approach

air conditioning and climate control
plant and equipment – the right kit
use the energy hierarchy approach first, then,
chilled water not dx for cooling and dehum
hot water not electric heating
avoid economy cycles
ultrasonic or modulating steam humidifiers rather than spray
quality sensors and recalibrate regularly
consider local support and expertise with chosen equipment
get the right advice

museum and gallery lighting
identify/scope major considerations regarding the phase out of inefficient incandescent lighting
review viable replacement options in light of recent industry developments, trends, issues and timelines

museum and gallery lighting survey 2011
existing lighting infrastructure and light sources
the nature and light sensitivity of the exhibits
criticality of good colour rendition
budgets

relevant lighting codes and standards include Guidance on Conservation Australian Standards Building Code of Australia Minimum Energy Performance Standards (MEPS)

global phase-out of the incandescent light sources

lamp manufacturers phasing out certain lamps

Lamp manufacturers phasing out certain lamps

Impact of lamp phase out on exhibition lighting

Impact of lamp phase out on exhibition lighting Ingo Mauer

Impact of lamp phase out on exhibition lighting most incandescent lamps are highly likely to be phased out in the next 5 years

- bulk stocking - direct replacement alternative lamp technologies - replacement of the luminaires with alternative technologies common strategies to manage the impact of the lamp phase-out

considerations when assessing alternative light sources for museum and gallery lighting
light quality
environmental sustainability
operation
durability and maintainability
budget-ability

Correlated Colour Temperature (CCT)

Colour Rendering Index (CRI) a number between 0 and 100 rating the colour rendering quality of a light source based on the sample colours.

Spectral Composition

Luminous Flux (Lumen) Luminous flux Φ describes the total amount of light emitted by a light source. It is measured in Lumens.

Efficacy Efficacy ( lm/W ) = luminous flux(lm) / power consumption(W) The effectiveness (efficiency) of a lamp in producing light (lumens) relative to the power (watts) required to operate the lamp

Lamp Life usually denoted in hours. e.g. most incandescent sources have 1,000-5,000 hrs lamp life whilst led do have 30,000 - 50,000 hrs.

considerations when assessing the alternative light sources for museum and gallery lighting
light quality
cct, cri, spectrum, luminous output, distribution
environmental sustainability
embedded energy, efficacy, disposal, recycling
operational suitability
flexibility(focus, relocate, readjust etc.), ease of controls, dimmability, instant restrike, tunability
durability and maintainability
lamp life, replacements, futureproofing, access
budget-ability
capital, operational and replacement costs

common alternative sources for exhibition lighting in 2011

steensen varming
3 different occasions in 3 different occasions
A total of 88 participants: curators, artists, conservators, exhibition lighting technicians, facility and building managers, architects and designers…
6 identical displays composed of white surface and various colour samples
6 different light sources (incandescent, metal halide, white son, fluorescent and led)

match the right light source from the given list

steensen varming
identify your favourite light

-maintain the focus on providing a better overall exhibition experience (presentation and preservation) -be open to alternative technologies and their capabilities -rethink the conservation requirements for lighting -consider it as an opportunity: it is a time well-designed and tailored exhibition lighting can provide substantial cost savings in the long term Possible way forward for sustainable exhibition spaces
