77 percent of Survey participants have energy programs to improve the portfolio’s efficiency. Some of the elements included in these programs focus on relatively low-cost activities, such as system commissioning (68 percent), building energy management systems (54 percent), and lighting programs (42 percent). These measures are often included in standard operational maintenance plans, indicating that most participants’ programs already identify efficient and cost-effective improvement measures. However, a large number of participants also include more extensive elements in energy efficiency programs, such as wall/ roof insulation (78 percent), window replacements (72 percent), and HVAC upgrades (58 percent). Interestingly, smart grid/smart building technologies are becoming more prevalent among property companies and funds, with 50 percent of benchmark participants including these technologies in building efficiency programs. In addition to energy and water conservation programs, 64 percent of participants also undertake indoor air quality (IAQ) assessments, with 19 percent using external assessments. Indoor environment quality is increasingly being recognized for the value that it brings, e.g. the ability to attract and retain tenants, thereby improving returns for the building owner. Elements included in IAQ assessments are, for example, HVAC inspection (60 percent), air sampling (49 percent) and legionella risk assessments (48 percent).
