Konstructa Energy-Saver Plus site offices provide a significant 76% reduction in energy usage and carbon emissions and an 87% saving on running costs compared to traditional site cabins.
Benefit from 87% reduced running costs
A host of energy efficient features result in a running cost of just £2.06 per week and can deliver cost savings of over £13 per week (or £702 per year) compared to a standard site cabin.
Reduce emissions to meet targets
In line with the targets of the Strategic Forum for Construction and the Carbon Trust, cutting carbon emissions is more important than ever and the new Konstructa Energy-Saver Plus building can help you to reduce your carbon footprint and save energy.
The huge energy savings are achieved through:
- Upgraded under-floor insulation - for improved heat transmission values (U-values)
- Additional improved insulation of the walls and roof - to further reduce heat loss
- Further insulation savings achieved due to a thicker door and a new double-glazed window design
- Improved heating system, using an innovative split heat pump which uses energy from the air outside - producing approximately 4.5kW of heating for every 1kW of electricity consumed
- High frequency lighting - an efficient type of illumination that uses less energy
- Passive Infrared (PIR) motion detection sensors - mean lights are off when they aren't needed, reducing lost energy by around 7%
- Time clocks on heaters - to prevent wastage
- CFC-free ozone friendly foam insulation - which performs 42% better than the rock wool alternative and delivers exceptional insulation. It also has an ozone depleting potential of zero and a thermal conductivity of 0.025W/mK.
- 56% reduction in electrical capacity - meaning less energy consumption is required on site
A Konstructa Energy-Saver Plus site office produces carbon emissions of just 1,136kg C02 per year, which is exceptionally low compared to traditional site cabins.
All our buildings achieve ISO 14001 accreditation for control of environmental impact, and they can help you to:
- Achieve Considerate Constructors Scheme certification
- Gain an excellent BREEAM rating
- Alleviate the impact of the CRC Energy Efficiency Scheme
It's easy to save money and enhance your corporate reputation!

2 The Energy Performance Certificate (EPC) for the typical site cabin is based on similar assumptions to the EPC that has been officially lodged for the Konstructa Energy-Saver Plus building.
Notes:
- The energy-use and carbon-emission figures quoted are based on grid supplied electricity and include an allowance for small power loads at 11.5 W/m2 but not Domestic Hot Water (DHW) loads However, the Energy Performance Certificate (EPC) rating quoted does not include the small power loads but includes for DHW loads.
- Since this building does not include any ablution facilities the following DHW system has been assumed for EPC calculation purposes and would be practical and achievable for this type of building;
- Direct electric storage heater located close to the ablution facilities and designed such that NO secondary circulation
and pumping is required i.e. it is main pressure/gravity fed. - 20 litres storage allocated to this building with a cylinder heat loss of 0.0133 kWh/litre.day.
- 98% delivery efficiency which means insulated hot water distribution pipework to minimise losses from dead legs.
- The A-rated Energy Performance Certificate (EPC) for the Konstructa Energy-Saver Plus building is based on the National Calculation Methodology (NCM) Office type profile, located in Manchester and having an air permeability of 3m3/hr/m2@50Pa (see certificate no 0551-0439-5179-5001-3002 - formally lodged by an Energy Assessor meeting English EPC Standards). The other EPC ratings and the figures quoted are estimates only however they are based on similar assumptions to the Konstructa Energy-Saver Plus building.
