Profile : ENERGY ADVISORY ASSOCIATES
Business SectorBuilding services/energy consultancy
Business descriptionConsultants on the more efficient use of energy in buildings.
Main business activities
- Energy design, new buildings
- Ditto, major refurbishments
- Energy surveys, existing buildings
- Specialist briefing reports for government and others
Company philosophyAs a consultant to lay people, architects and other professionals, a major aim is to dispel a number of widespread myths/misconceptions and to help others to adopt the most effective CO2 reduction strategies.
Energy EfficiencyFor the last 25 years, the only building projects worked on have been those near the top of the UK energy efficiency scale. It is hoped that the three projects listed, which were constructed 13-20 years ago, help to make this point. (More recent projects will be listed as and when this site allows.)
Reducing the environmental footprint of the businessThe aim is to operate the business with lower CO2 emissions year by year, but without relying for such claims on doubtful techniques; e.g., carbon offsetting, green electricity tariffs and biomass combustion. Long-distance travel within the UK is undertaken by train, wherever practicable. Within a few years the business will be operated from an office with no net CO2 emissions.
ENERGY ADVISORY ASSOCIATES : Projects
New mid-terrace infill house, S W LondonProject Date 1990
scope Energy consultant.
aims To go as far as possible with proven technology at the time (1984).
measures Very good insulation for the time, mechanical ventilation and heat recovery, condensing gas boiler, high thermal capacity.
monitoring Since 1990 has used about 60% less energy per m2 than the UK norm (in 2007) for space heating. More information in BRECSU General Information Reports 38 and 39 (1996).
Stays cooler in summer heatwaves than any of the other houses in the neighbourhood. Unexpected result as the house was designed above all for winter thermal comfort. In summer 2003 was said to be the only house in the area which was comfortable without air conditioning.
New detached house, Charlbury, OxonProject Date 1992
scope Energy consultant
aims To go as far as possible at the time with relatively proven, off-the-shelf technology.
measures High levels of insulation (for the time), good airtightness, mechanical vent. & heat recovery, condensing boiler, energy-efficient lighting and appliances.
monitoring Has used about 50 kWh/m2yr gas and 12 kWh/m2yr electricity since measurements began in 1993.
Elizabeth Fry Building. UEA, NorwichProject Date 1994
scope Energy consultant. Worked with the architects in particular to improve the detailing of the building thermal envelope. Had some role also on other decisions which affected energy consumption.
aims Client's brief asked if possible for a building which avoided the need for a normal central heating system. Also wished to improve on another new university building (commissioned a few years earlier) which used over 6 times as much gas as this one and had high maintenance costs for the heating system and for the solar control blinds.
measures High insulation, comparable with Scandinavian levels of the time.
Very high thermal capacity. Very good airtightness (for the UK).
2+1 Swedish windows, U-value 1.35 W/m2K, with solar control blinds mounted in the outer non-sealed airspace and protected from damage.
Swedish Termodeck system - the hollow-core concrete floors are used as part of the building's ventilation and heating systems.
As a result of the low heat loss, a 3500 m2 building can be heated by two domestic wall-mounted gas condensing boilers.
