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

preliminary findings

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

-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

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 qualitycct, cri, spectrum, luminous output, distribution

-environmental sustainabilityembedded energy, efficacy, disposal, recycling

-operational suitabilityflexibility(focus, relocate, readjust etc.), ease of controls, dimmability, instant restrike, tunability

-durability and maintainabilitylamp life, replacements, futureproofing, access

-budget-abilitycapital, operational and replacement costs

common alternative sources for exhibition lighting in 2011

steensen varming museum and gallery lighting survey 2010

-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)

steensen varming museum and gallery lighting survey 2010

-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
