Article
The design of the mode of operation of heating, ventilation and air-conditioning systems in office buildings has become increasingly important in recent years. This is due mainly to their relationship, both with the comfort of their occupants and with energy efficiency. The adaptive thermal comfort theory addresses this problem by linking the indoo...
Article
In recent years, the urgent need to adapt our lifestyles and buildings to deal with a more extreme and a warming climate has become clear, not least through the increasing overheating of buildings. This is reflected in the rising concerns about the discomfort and heat stress to building occupants caused by the increasing indoor temperatures. Europe...

Article
Full-text available
The reasons for the inferior performance of many existing buildings and associated energy systems are diverse, but an important part-cause is insufficient attention to the influence of occupant behaviour. In smart buildings it is necessary to allow for the integration of human behaviour in the HVAC system. In addition, many researchers are limited...

Preface to the Proceedings of the 9th Windsor 2016 at Cumberland Lodge, Windsor For many the costs of providing acceptable indoor temperatures have become prohibitive. Around the world people already have to make stark choices on whether to spend money on heating and cooling or on eating. The science of comfort developed in the 20th century around...
Conference Paper
Full-text available
The awareness of climate change and the increasingly urgent need to reduce carbon emissions in buildings and cities is growing in parallel with concerns with the comfort of occupants due to the rising temperatures. Recent comfort theories have acknowledged the interaction between people and their surrounding environment. BS15251 and TM52 have sugge...
Article
Executing a life cycle carbon analysis on a building has two components to consider: the Embodied Carbon (EC) and In-use Carbon, the sum of these forms ‘the building carbon budget'. The in-use can be obtained through regulatory tools such as the Standard Assessment Procedure (SAP) in the UK. Embodied carbon has a loose framework with little guidanc...

Buildings are responsible for almost 50 per cent of the UK's energy consumption and carbon emissions. Therefore improving the energy efficiency of the built environment is fundamental if the UK is to meet the proposed objectives of reducing energy consumption and the depletion of fossil fuel resources without harming the environment. Thermal energy...
Article
Full-text available
Achieving a pleasant indoor environment with low energy consumption is a major goal of good building design. With high levels of insulation to reduce fabric heat losses, heat loads associated with infiltrations in dwellings in the UK have gone up from one fifth to one third. This has made it imperative to reduce infiltration rates to a minimum cons...

In sunny climates, obstructions impair considerably the access to daylight by reducing the skylight contribution and sometimes blocking the access to sunlight. However, reflected sunlight from the obstructions or the ground can play an important role in the illumination of buildings, particularly in orientations and at times of the day where sunlig...
Article
Full-text available
Daylight calculations are usually based on uniform or overcast skies, but in areas where clear skies are predominant it may underestimate the illuminance levels and might lead to inappropriate urban and window design. In urban canyons reflected sunlight from obstructions and ground is a major contribution to the illumination of buildings in orienta...
Article
Full-text available
Daylight calculations are commonly based on the daylight factor method regardless of prevailing weather conditions. While this method may be used for overcast sky conditions, it can be argued that it is not appropriate for clear skies. Furthermore, reflected sunlight from obstructions and ground is a major contribution to the illumination of buildi...
Article
Full-text available
In northern Europe the average daylight factor may be used to characterise the daylight in a room. The paper discusses calculation techniques and their limitations in practice. It further deals with daylighting in urban canyons in predominantly sunny climates particularly those north facing rooms lit by reflected sunlight.
