About this building

3-8 Whitehall Place

3 Whitehall Place is a Grade II listed building built by the Ministry of Works in 1951/52 as an extension to 55 Whitehall. The architect was CE Mee. The building is five storeys high with a set-back attic storey. The building was completely renovated in 2003/04 with the original façade retained and restored. The reconstruction also inserted a small central atrium, added new sixth and seventh floors behind the original parapet and placed air-handling plant, chillers and pumps on the roof. The renovation project received the RICS Award for sustainability in 2005.

Display Energy Certificate

Since 9 January 2013 public buildings in the UK over 500m2 have been required to display a Display Energy Certificate (DEC) prominently at all times. Display Energy Certificates were introduced by the Government in response to the EU Energy Performance of Buildings Directive which all EU member states were required to implement by January 2009.

DECs are designed to promote the improvement of the energy performance of buildings. They are based upon the actual energy performance of a building and increase transparency about the energy efficiency of public buildings. DECs use a scale from A to G with A being the most efficient and G the least. The Display Energy Certificate for 3-8 Whitehall Place is available here or by clicking the plaque on the right.

Notes about 3-8 Whitehall Place

Notes about 3-8 Whitehall Place

How do you calculate the CO2e emissions from a unit of energy used?

Energy retailers and the government produce conversion factors that describe the typical carbon impact of different energy sources. These allow us to take the energy uses (in their respective units), and calculate the approximate carbon dioxide emissions, normally measured in kilograms of carbon dioxide equivalents (kgCO2e). Defra's UK conversion factors may be found at Defra's 2018 Guidelines. .

What do the colours on the graph mean?

For buildings, the colours in the graph show approximately how the current level of usage would lead to a given Operational Rating – as set out on a Display Energy Certificate (DEC) – if the performance for a given moment carried on for an entire year. This goes from dark green for ‘A’ to red for ‘G’. We calibrate this using input data used for generating the building’s DEC, together with information relating to 'normal' buildings of its type. If we do not have data for all of the utilities noted in the DEC then the graph will appear in a light-blue colour scale, to indicate that the usage displayed on the graph is not representative of the full energy use of this building. Graphs for communities also show in this blue colour scale.

Why are you using these units and what do they mean?

We provide three different measures of the energy used: the amount of energy, its monetary cost, and the carbon impact of the energy used. Energy use is measured in kilowatt hours (kWh), which are the standard units of a home energy bill (1kWh is the amount of electricity used by ten 100W light bulbs in one hour). For electricity this number represents the amount of energy that flows into a building through the meter, and excludes distribution losses. For gas it is the amount of energy that is theoretically available by burning all the gas in an imaginary ideal burner. For district heating it reflects a flow of temperature into the building over time (after the heat produced by burning the fuel has been transported to the meter, which involves other losses). So each of these numbers, while all being measured in kWh, mean very different things. This is one reason that we prefer to use 'units per hour' when combining them. In some ways it would be more correct not to combine them at all, because combining them implies that the measures are comparable. This is a global challenge though, and conventions have become established around combining kWh. So we'll have to fix that another day. Monetary cost is calculated using the costs per 'unit' for each utility in every building. The figures used are noted below in the Notes section. The carbon impact is measured in kg of CO2e (the e stands for equivalent) which takes other climate-affecting gasses into account in addition to carbon dioxide.

How much does this organisation pay for its energy?

Prices come from the latest energy bills for Department of Energy and Climate Change, which for Gas average out at 4.82p per unit and for district heating average out at 0.2433p per unit and for electricity average out at 0.52462p per unit. The gas volumetric measurement is converted to kWh using the meter correction factors and calorific values supplied by the utility company. These may be subject to change.

Can you show data from the transport emissions of this organisation/ building?

Data of CO2e emissions created by transport used by organisations is very interesting and powerful data to show here. We are working on ways to display and reduce the transport impacts of different organisations, and you will see some of the products of this work on these pages very soon.

Why does this building use energy at night and weekends?

Energy use drops significantly during the night and at weekends as there is no virtually heating or cooling, limited lighting and no or little use being made of laptops, printers and other IT equipment. However, some power is still required to provide some heating (if needed) and hot water for security guards. Also the IT chiller may be operating to keep the server room from getting too hot. Some staff work at the weekends and this is often when any maintenance or other buildings works are carried out.

Is there a policy for heating and cooling this building?

Yes. We aim to keep keep temperatures between 20°C and 26°C between 8am and 6pm, Monday to Friday. Generally this is achieved by turning on heating to a general office floor when the average internal floor temperature falls below 20°C and, cooling when they exceed 24°C. In addition to automatic control by the building management system, we use weather forecasts and monitor temperatures and other environmental conditions on the ground to optimise energy efficiency and working conditions.

Do you ever heat and cool the building at the same time?

No. We have a building management control system that monitors the average temperature on each floor and turns on the heating supply to the whole floor if the temperature falls below 20°C or the cooling if it rises above 24°C. It does this by taking sample readings from six designated temperature sensors on each floor, calculating the average temperature and turning on or off the hot water or chilled water valve for the floor accordingly. The result of this is that no floor will be provided with heating unless the average temperature for that floor is below 20°C or cooling unless it is above 24°C but never at the same time. We do not enable our main building cooling system when the main heating system is running and vice versa. Therefore there is no possibility of conflict between the heating and cooling systems within our buildings.

How do you get this data from the buildings?

Getting this energy data out of some buildings is harder than others, but in general the buildings contain a small low-power computer which takes very frequent readings from the electricity and gas meters and stores the data. Every few seconds, this computer sends the information it has collected to a server. Your browser will then ask this server for the data it needs in order to draw the real-time detailed graphs and website teasers. The energy impact of this process is very low, and it gets lower with each additional site that uses the system.

What services do the electricity consumption figures relate to?

IT equipment, particularly PCs and laptops, cooling and lighting are the main users and running essential services such as ventilation, water supplies and lifts etc.

Can I use the data to break down the gas or electrical consumption in more detail?

No. This real time energy data is collected from the main electricity and gas meters only. However, we have many sub meters which show the power and gas consumed in individual areas of the buildings and that consumed by our central plant and equipment and this data is used internally for energy management.

What are the red spikes that appear through the week?

These red spikes have created a lot of interest. It isn't obvious what they represent unless you know how the building's systems work. The spikes show the gas demand caused by DECC's boilers firing up to heat the hot water for the sinks and showers, etc. There is a heavy load first thing in the morning to get the system up to temperature before occupancy starts to ramp up and then during the course of the day the boilers fire up under lighter load to keep the temperature of the water at the correct level. The visualisation tells us a lot about the way the building works, and how the building is managed. We're not sure yet how widespread this spiky pattern will be among buildings, some may be much smoother. Seeing the graphs for different buildings will tell building managers a lot about the different approaches that are in use, and help to drive efficiency improvements.

What services do the gas consumption figures relate to?

We use gas mainly to heat our hot water and a small amount for cooking as 3WP houses our staff restaurant. Space heating is a relatively small part of our overall gas consumption as the building is inherently warm due to heat from sunshine through the windows (known as ‘solar gain’) and the heat generated by the people and energy-consuming equipment in it.
