  1. To help reduce heat loss, always insulate hot water pipes, especially where they run through unheated areas. Never insulate plastic pipes.
  1. Iron clothes and linen all in one go. Do not keep a hot iron which is switched in an upright position for long period since more heat will be lost.
  1. Avoid storing hot / warm food in the refrigerator.
  1. Use of white or light colours for interior walls, ceilings, curtains, drapes and furniture reflects more light within the building and therefore further reduces the cost of lighting.
  1. If your refrigerator is not frost-free, defrost it regularly. Auto defrost refrigerators consume more electricity. The larger the refrigerator, the higher will be the usage of electricity.
  1. Reduce lighting where possible and take advantage of natural daylight.
  1. Clean or vacuum the refrigerator coils at least twice a year.
  1. Install a low-flow showerhead.
  1. Maintain the water heater by draining the sediment at least once a year.
  1. Make sure the door gaskets on freezers and refrigerators fit tightly.
  1. Look for energy efficient appliances when shopping.
  1. Read the manuals for your home appliances. They may offer more specific instructions for saving energy.

Exterior lighting is the integral part of any building type and this is to enable ease assess to all the occupant and also to each and every individual who visit building. The exterior lighting level is well defined by the ASHRAE 90.1, that also include exterior lighting for the variety of buildings. Brief summary is as follows:

Facade lighting :
paving               : 

Landscape         :
For more, please refer section xx of ASHRAE 90.1 - 2010.
1. Stand by equipment consume power  
In general, we are equipped with laptop/palm top/ipad/ipod, mobile/ cell phone and camera charger/ adapter, projector, printer, scanner etc. consume power even in stand-by mode. For efficient use, before we leave workstation, switch-off all such equipment/ devices 

are not plugged to particular device. 

2. Cleaning of FTL and Fluorescent Bulbs
It is very important to clean FTL (Fluorescent Tube Light) and Fluorescent Bulbs regularly. Once dust is get deposited, illuminance level reduces and we try to increase lighting level. So dust them our frequently or with a time frame.

3. Select Energy Efficient Lighting fixtures
when-ever, where-ever possible, energy efficient lighting fixture should be installed. Incandescent lamp to CFL, to LED ones. This would enable reduction in energy and also higher hife of illuminaire. As evident that CFL and FTL converts electricity into light about 5 times more than the bulb.

4. It is also revealed that 90 % of the energy consumption of an incandescent lamp released into heat and 10 % provides light. Later, this heat has to be removed by air-conditioning units. Selection of energy efficient lighting fixture can reduce lighting energy consumpation and also save significant operation cost of air-conditioner.

5. Reducing temperature settings of Electric Geyser or Heater can also reduce significant energy (Lets say - temperature from 55 deg C to 48 Deg C or even less which is very comfortable for bath).

6. Proper insulation for chilled water pipes, Ducts and hot water pipelilnes can reduce loss of cooling and heating.

What is adaptive thermal comfort ?

Image
Overview Field studies of thermal comfort have been conducted intensively at various climatic locations to define the range of acceptable thermal environment for air-conditioned and naturally conditioned buildings that led to the development of Adaptive Thermal Comfort (ATC) model.  Research on adaptive thermal comfort revealed a higher range of acceptable temperatures, which depend on climate, building type, behavioral controls, and other similar factors. Field studies have also revealed the role of thermal adaptation to conserve energy in air-conditioned buildings, and this concept is also useful for building design, and operation of naturally conditioned buildings as per the outdoor conditions.  Higher bandwidth of comfort temperature and energy conservation opportunities encouraged researchers to carry out intensive field studies of thermal comfort to propose robust adaptive thermal comfort model. Definition Adaptive principle states that if a change occur...

ISO 7730 for Thermal Environment Evaluation

ISO 7730 is an International Standard for 'Ergonomics of the Thermal Environment-Analytical Determination and Interpretation of Thermal Comfort Using Calculation of the PMV and PPD and Local Thermal Comfort Criteria’.  ISO 7730 illustrates methods to evaluate the general thermal sensation and the degree of discomfort for occupants exposed to moderate thermal environmental conditions. This Standard grouped the thermal environment into three different categories namely  Category-A,  Category-B and  Category-C  All there  categories  are described with the help of Table given below.  Category-A describes narrow comfort conditions, whereas Category-C prescribes wider comfort bandwidth (-0.7 < PMV < +0.7). The Standard describes the calculation of PMV and PPD indices for thermal comfort and for local discomfort. The Standard also defines the local clothing habits for indoor comfort and but does not provide information for cl...

EN 15251 for Energy and Thermal Environment Evaluation

Comfort standard EN 15251 (version released in 2007) is entitled to ‘Indoor environmental input parameters for design and assessment of energy performance of buildings–addressing indoor air quality, thermal environment, lighting and acoustics.’  The Standard EN 15251 deals with energy performance of buildings as well as indoor environment quality such as thermal environment, indoor air quality, acoustic comfort, and visual comfort conditions to provide more comfortable indoor climate and that is also energy efficient.  Previous research  (Nicol & Wilson conducted study in 2010)   has examined that EN15251 Standard helps building designers to optimise the building energy consumption, considering thermal, air quality, acoustic and visual comfort. Furthermore, studies carried out under SCATs (Smart Controls and Thermal Comfort) research project reveal that this Standard involve  only   European countries for energy and comfort evaluation. SCAT s...
