We invest in remote systems to monitor and record electricity consumption in our properties including entire buildings and individual suites.
Our systems enable us to benchmark consumption and quantify savings achieved in quantity and cost. The impact of the installation of energy saving equipment can be analysed and the payback forecast more accurately.
The greatest savings often come from improved premises and workplace management. We work with tenants to analyse consumption and identify where savings are possible. This can be as simple as implementing a "switch off" policy particularly over weekend and holiday periods or identifying particularly inefficient plant or equipment. Where possible we buy green power generated from renewable resources.
ELECTRICITY SAVING INITIATIVES INCLUDE:
- We have installed monitoring equipment at key sites to enable us to record and analyse consumption of oil, gas, water and electricity. Working with one of our tenants to help identify where excess power was being consumed, we achieved a total reduction of 20% and therefore saved overall costs.
- We have installed voltage optimisation in two sites and will be including more soon.
- We reduce lighting loads with the use of high frequency fluorescent and LED (light emitting diode) light sources.
- We install occupancy and solar controlled light switching.
- We purchase only low energy equipment.
- Where electric heating is used we use advanced controls.
Case Study - Kingmead Square, Bath
7.4% reduction in annual electricity use.
Supplies are separately metered enabling us to measure usage in specific areas and make comparisons.
Audit all electrical equipment for energy consumption
Assessed opportunities to reduce load and improve control.
Advanced control for electric space heating system - Dataterm
Project - 27 Gay St, Bath - Lighting Audit
Expected lighting consumption reduced by 70%
The building had undergone a full refurbishment in 1995 and achieved a BREEAM Excellent award at that time.
In 2012 we carried out an upgrade which included updating the lighting installation.
Our intention was to retain as many existing fittings as possible, re-lamping with LED replacements in place of the existing compact fluorescent lamps. All the luminaires in the main rooms were retained. 50W halogen fittings in the stairwell were replaced with LED fittings and in the stairwell and ancillary areas motion and solar detection controls were introduced.
The total consumption of electricity after delivering both reduced load and greater control is expected to be just under 30% of the previous level.
